UK-Iceland cable on the Global Infrastructure 100 List

A global panel of independent industry experts has identified a subsea electric cable between Iceland and the United Kingdom (UK) as one of the hundred most inspirational and innovative infrastructure projects in the world – many of which are expected to transform the way the world’s populations interact with their cities, governments and environment. This is the first time that an infrastructure project in Iceland is on this list, which is published by KPMG (download the report as pdf here).

KPMG-Global-Infrastructure-100-2014-coverKPMG International’s ‘Infrastructure 100: World Markets Report highlights key trends driving infrastructure investment around the world. In the report, a global panel of industry experts identifies 100 of the world’s most innovative, impactful infrastructure projects. Furthermore, the panel demonstrates how governments are coming together with the private sector to overcome funding constraints in order to finance and build projects that can improve quality of life – both solving immediate needs and planning for future societal demands.

The 2014 report focuses on key trends driving infrastructure investment in four key markets, one of the categories being smaller established markets, which are strong domestic markets open to private finance in infrastructure.

The subsea electric cable between Iceland and the UK is one of 25 projects falling under this market-category. The report describes the project, called IceLink, as an ambitious attempt to connect the power grids of Iceland and the UK. Iceland produces all of its electrical power by the means of renewable energy, such as hydro, geothermal and wind, and has potential well beyond local consumption.

According to KPMG, the total investment in the cable and related production and grid infrastructure in Iceland has been assessed in the range of USD 5 billion. When completed, this clean-tech venture would be the world’s longest subsea power cable, delivering as much as 5 TWh a year of renewable electricity to the UK – at a cost lower than offshore wind in UK territories. KPMG says that UK-based ventures have shown interest in funding the interconnector, while Icelandic power companies will build the power-generating facilities and onshore infrastructure in Iceland

KPMG-Global-Infrastructure-100-2014-enregy-and-resources-list-smallOf all the 100 projects listed in the 2014 KPMG-report, 27 projects are in the sector of energy and natural resources. Besides the IceLink, these projects are for example the Alaska LNG Project, the UK Hinkley Point C Nuclear Power Station, and Russia-China Gas Pipeline.

A total of 25 projects are classified as being in smaller established markets. The IceLink is one of these projects – other projects in this category are for example the Facebook Rapid Deployment Data Center in Luleå in Sweden, the Scandinavian 8 Million City High Speed Rail Link between the capitals of Norway, Sweden and Denmark, and the Rail Baltica, linking Finland, Estonia, Latvia and Lithuania with 960 km of railway track. Although many of the projects in this category face challenges regarding scale and investment, KPMG believes there are good possibilities to realize all the projects with increased access of private investment. With IceLink in mind, a perfect and realistic business model might be a private ownership of the cable, while the Icelandic TSO and the main Icelandic power firms would probably be in majority governmental ownership, possibly with private investors as co-owners.

IceLink offers high increase in social and economic welfare

ENTSOE-HVDC-Iceland-2014-coverThe European Network of Transmission System Operators for Electricity (ENTSO-E)  has submitted the final draft of the community-wide Ten-Year Network Development Plan (TYNDP) to the Agency for the Cooperation of the Energy Regulators; ACER. Following reception of the ACER opinion, the final TYNDP 2014 will be published by end of December 2014.

The TYNDP 2014 explores the evolution of the electricity system until 2030 in order to identify potential system development issues and to be able to address these proactively. The objectives of the TYNDP are to ensure transparency regarding the electricity transmission network and to support decision-making processes at the regional and European level.

IceLink would result in highly increased social and economic welfare

The report from ENTSO-E includes analysis and evaluation of numerous possibilities for new electric cables interconnecting different electricity markets in Europe. One of the possible cables is a submarine HVDC cable (High Voltage Direct Current) between Iceland and the United Kingdom (UK); sometimes referred to as IceLink. The cable is expected to have a capacity somewhere between 800-1,200 MW, and be close to 1,000 km long.

ENTSOE-HVDC-Iceland-2014-mapAccording to ENTSO-E the IceLink could offer an increase in social economic welfare of up to 470 million EUR annually. This is higher SEW than most other of the interconnectors evaluated by ENTSOE-E in the new report. The social and economic welfare (SEW) is characterized by the ability of a power system to reduce congestion and thus provide an adequate transmission capacity so that electricity markets can trade power in an economically efficient manner. In addition, the IceLink offers much more flexibility or steerability than for example the numerous large scale wind power projects, evaluated in the report.

ENTSO-E presents four different scenarios

The 2014 version of the TYNDP covers four scenarios, known as the 2030 Visions. The visions were developed by ENTSO-E in collaboration with stakeholders through the Long-Term Network Development Stakeholder Group, multiple workshops and public consultations. The four visions are contrasted in order to cover every possible development foreseen by stakeholders. The visions are less forecasts of the future than selected possible extremes of the future so that the pathway realized in the future falls with a high level of certainty in the range described by the visions. The span of the four visions is large and meets the various expectations of stakeholders. The four visions for IceLink have a span of 290-470 million EUR annually in increased social and economic welfare.

Top-down, open and constantly improving process

The first Ten-Year Network Development Plan was published by ENTSO-E on a voluntary basis in 2010. The 2012 release built on this experience and the feedback received from stakeholders, proposing the first draft of a systematic cost benefit analysis. In the last two years, ENTSO-E has organized exchanges with stakeholders to ensure transparency as much as possible.

ENTSOE-HVDC-Iceland-2014-1For the 2014 release, ENTSO-E launched a large project, where the expertise of the members of ENTSO-E; the Transmission System Operators (TSO’s). This included the Icelandic TSO; Landsnet. Having regard to the high SEW of IceLink and its highly flexible power production, it can be expected that the project will attract strong political interest and positive financing.

Norway’s positive experience from interconnectors and open electricity market

Earlier this month, Mr. Ola Borten Moe, former energy- and petroleum minister of Norway, was in Iceland, discussing the development of the Norwegian electricity market.

In a presentation, at the Harpa Conference Hall in Reykjavík, Mr. Borten Moe gave a comprehensive insight on the matter. This open meeting took place on September 9th (2014) and was hosted by VÍB. The meeting was very well attended; in addition to the crowd at the hall at Harpa close to two thousand people watched the event live on the web (where a video recording is now available).

Iceland-Energy-Harpa-September-2014_Norway-Borten-Moe_Ragnheidur-Elin-Arnadottir_Hordur-Arnarson_Ketill-Sigurjonsson-1After the keynote speach by Mr. Borten Moe, there were panel discussion with three more participants; Ms. Ragnheiður Elín Árnadóttir, Icelandic Minister for Energy and Industries, Mr. Hörður Arnarson, CEO of Landsvirkjun Power Company, and Mr. Ketill Sigurjónsson, Managing Director of Askja Energy Partners. In his presentation Mr Borten Moe especially focused on two main issues; .Norway’s experience from the liberalization of the electricity market and Norway’s experience from the interconnectors (electric HVDC cables) between Norway and outher countries. Here we will highligt some parts of Mr. Borten Moe’s presentation. For reference, we will quote a transcript from the meeting, now accessible at the website of Landsvirkjun.

Positive economic and environmental effects

Mr. Borten Moe explained how the Norwegian deregulation of the elctricity market, which happened in the 1990’s, became a model for similar changes in Europe a decade later. He also described how interconnectors (electric cables) between Norway and other countries have benefitted both the Norwegian people and the domestic energy industry in Norway.

According to Mr. Borten Moe, the market deregulation and the interconnectors have been very positve for the Norwegian society. It has lead to more efficiency in the Norwegian hydropower industry, wich is mostly in public ownership. Also Mr. Borten Moe stated, that the interconnectors have resulted in a better access to electricity supply, which has especially been important for Norway in dry periods (as Norway’s electricity generation is almost 100% based on hydropower). Even more, the result of the more competitive electricity market has not only been the financial benefit, but also a better stewardship of the natural resources. In Borten Moe’s own words:

Iceland-Energy-Harpa-September-2014_Norway-Borten-Moe-1“We [Norwegians] experienced a huge efficiency gain in the power production industry. And not did they only turn around all the heads in all of the industry, but […] also turned around the head to everyone owning the industry. Meaning that thousands of people could be liberated or do something else and more productive for society.”

“From the mid-1990s and outwards, the [electricity generating] industry produced huge surpluses, and these are values that are put back into work for the Norwegian society through the fact that there are municipalities, counties, and the government owning it. So we build roads, we build schools, we build health care systems for the values created in our power industry.”

“I foresee Norway being willing to take a bigger place when it comes to capacity regulating systems, using our hydropower system more to regulate for necessary regulations of the European power markets being more dependent on renewables […] and also maybe even selling electricity, being a net exporter. That is basically what we do with oil and gas.“

“So far in Norway, this has been the story that I told you. It has been more well functioned markets, increased efficiency, more values created, more security of supply and now lower electricity prices because we have introduced more production capacity into the market.”

Efficiency in the electricity industry serves as natural protection

The Norwegian electricity market was tightly regulated up until the 1990’s. This meant very limited competition. Low returns were a normal condition in the electricity production and this lead to over-investment in the hydropower sector. One of the effects of the deregulation was more access to economical supply outside of the former small highly regulated markets in Norway. Thus, the deregulation served as an incentive to not utilize some of the less economic hydropower sources. Or as Mr. Borten Moe explained:

Iceland-Energy-Harpa-September-2014_Borten-Moe_Ragnheidur-Elin-Arnadottir_Hordur-Arnarson_Ketill-Sigurjonsson-panel“[My] predecessor, Eivind Reiten, who is the father of the new energy system, when he presented the new energy bill to Parliament in 1990, deregulating the whole sector as one of the first countries in the world, he said that this bill would save more Norwegian nature and water and waterfalls than any gang in chains would ever do. And he was right. So the deregulation and the market system in Norway has also been one of the biggest reforms to save Norwegian nature.”

“Norwegians strongly believe that access to electricity should be cheap, it should be unlimited, and it should be safe. And it should not disturb the nature, which basically means that you have a lot of wishes and demands and it’s not always very easy to fulfill all those wishes at once.”

“I think it is a fact that you need to consume nature to produce electricity and power but basically I would say that if you are to do it at least you need to produce a lot of money, a lot of values for society doing it.”

Competitiveness of Norwegian industries is still strong

The deregulation of the Norwegian electricity market and increased interconnectors have had fairly limited impact on industries in Norway; even energy-intensive industries. Electricity prices have indeed risen, but the competitiveness of the industry relies much more on the global market conditions rather than the electricity price in Norway.

Iceland-Energy-Harpa-September-2014_Borten-Moe_Ragnheidur-Elin-Arnadottir_Hordur-Arnarson_Ketill-SigurjonssonThe interconnectors and increased efficiency in the Norwegian electricity sector has been a success in increasing profits in the industry. One of the results is increased tax-revenues. This has created more possibilities for the Norwegian government to set up incentive schemes to positively increase investment of industries in Norway. When valuating the financial effects of the deregulation and more interconnected electricity market, the wholistic economic result in Norway has been very positive. As Mr. Borten Moe explained:

“What we have seen when it comes to our industries during the last 25 years, both through the deregulation and now with the more Nordic and European electricity market, is not that they have fled the country.”

“The world markets are far more important for the development of our power intensive industries than the electricity prices, and the electricity prices have not gone all that much up.”

“We see a new interest in reinvesting in Norway, Norwegian power intensive industries. Norwegian, our Norsk Hydro, which is our huge aluminum smelter company, is probably going to build a huge new smelter up in Karmøy [in Southwestern Norway].

Ola-Borten-Moe-Presenting-in-Norway-2011“And it is also a fact that in Norway, the power companies, the production companies, when they negotiate long term contracts, they know that they need the power intensive industries, after all, it’s their biggest clients. They use around 40 out of 120 terawatt hours, and if they go away, you would completely take the floor out of the Norwegian electricity market and the prices of the whole portfolio would go to the bottom. And they would lose a lot of money.“

“In Norway at least, I am convinced that we are not going to produce aluminum because we have cheaper prices than anywhere in the world or because we have lower regulations on the environment. On the contrary I think that we should have good prices on energy, meaning also [the aluminum smelters] should pay enough for the energy to make them wish every day they wake up to get a little better and a little bit more efficient and a little bit more competitive and it should be the same when it comes to environmental regulations.“

Stable and secure energy supply

According to Mr. Borten Moe, increased interconnection has contributed to strengthening the electricity supply for Norwegian consumers. Norway’s electricity production is close to 100% based on hydropower. In dry periods, less water in rivers and reservoirs can result in temporarily very high electricity prices and even problems in supplying enough electricity to meet the demand. The possibility of importing electricity through subsea cables and other interconnectors, makes it much easier for the generating industry to offer stable and secure supply of electricity.

Karahnjukar_Hydropower_spillwayThe interconnectors also offer the possibility to export electricity when prices at the other end of the cable (such as in the Netherlands) are high. This means that interconnectors improve yield and profitability of the utilization of hydropower resources in Norway.

With this in mind, it is interesting that on average approx. 10% of the water in the Icelandic hydro reservoirs flows through spillways. If Iceland would be connected with another electricity market (preferably fairly large market, such as the British or German markets) it could be very economic and efficient to add more turbines and utilize the spillwater to generate electricity and sell it through such a subsea cable (interconnector). With regard to this, it is interesting to consider Norway’s experience as described by Mr. Mr. Borten Moe:

“In 2003, I think we had a summation, a mind gobbling situation, because the prices of electricity peaked, and the population asked serious questions about is Norway really able to secure the amount of energy that we need when we need it, and at a price that is affordable. At that time, I would say that this was a fair question. And if you look at […] 2002, 2003 in this form, you’d also see that production was fairly low and that it was a combination of little rain, low temperature, and lack of import capacity that brought us into this situation.“

Norway-Electricity-Balance_2009-2013_SSB-table“In 99% of the cases we manage to get the electricity out on the market, use more of it but as you said, if we had been an island, well then we, the electricity that we [sold to] Sweden, Denmark, Finland, Russia, the Netherlands would have been water going over the dams.”

“The question of interconnectors in Norway is not only a question about selling electricity, or selling energy. It’s also a question about buying electricity, and it is a question about security of supply, even when the weather is dry and the weather is cold.“

Modest electricity prices for Norwegian households

In his presentation, Mr. Ola Borten Moe stated that despite increased interconnection of electricity markets the electricity price in Norway is generally less than for example on the European mainland. In the opinion of Borten Moe, the impact the interconnectiors have on the electricity price is limited in comparison with the effects of the relative supply and demand within each of the connected electricity markets. As Norway is currently increasing domestic investment in electricity generation, Mr. Borten Moe expects price reductions. In addition, Norwegians have used the revenue from the international connections to lower the electricity bill of Norwegian consumers.

Norway-Electricity-Prices_1998-2013“It is basically the balance in the market, or the lack of balance in the market, that is the most important factor for price. If we have good security of supply, a good balance in market, and slightly more production and consumption, prices will be fairly low.“

“In Norway we are interconnected, but not a part of a perfect market with the European electricity markets. There are still differences in price, between our price and the European price, and it will probably continue to be so.”

“The surplus from these interconnectors goes to lowering the electricity bills to all Norwegian consumers, including industry. So as long as they produce a surplus, it’s a direct benefit to the Norwegian household and the Norwegian industry.“

Issues to consider

The conclusion is that Norway’s experience from the increased interconnection of electricity markets has been positive. Mr. Ola Borten Moe stated that despite this fact, there are nonetheless several issues that Iceland must consider before it is possible to decide on the possible construction of a subsea cable between Iceland and Europe.

Iceland-Energy-Harpa-September-2014_Norway-Borten-Moe_Ragnheidur-Elin-Arnadottir_Hordur-Arnarson_Ketill-Sigurjonsson-HarpaBorten Moe expressed that the Norwegians emphasize the importance of utilizing their infrastructure in a sound economical manner and that further disturbance of the environment must be based on guaranteed profitability. He also mentioned that although subsea electric cables would generally have the effect that electricity prices at the markets at each ends of the cable have the tendency to be similar, at least to some extent, nevertheless it is the supply and demand in each market that is dominating in deciding the prices in each of the markets. As Borten Moe said:

“We like to have control over this kind of infrastructure, we need to know how much goes in, how much goes out. We need to keep control about how the values flow and who gets the benefits.“

Iceland-Energy-Harpa-September-2014_Borten-Moe_Ragnheidur-Elin-Arnadottir_Hordur-Arnarson_Ketill-Sigurjonsson-panel-questions

“It is possible to foresee a future when we use subsidies to get new electricity into the market, taxpayers’ money, new production capacity, and we sell this production capacity with a loss to the European markets and we lose both money and Norwegian nature. And that, of course, would be a whole different story.”

“If you have two markets and you make an interconnector, you will basically have a price that are more of the same. That’s the law of nature and the whole ratio for building such an interconnector. But it’s also fair to say that it’s also a question of what kind of capacity you introduce. In a perfect market, you would have the same price, but these are not perfect markets.”

IceLink offers flexibility rather than base-load power

In a recent publication, Getting Interconnected – How can interconnectors compete to help lower bills and cut carbon?, the British think tank Policy Exchange encourages the government of the United Kingdom (UK) to use subsidies to open up new electricity capacity market to power stations outside of UK. The electricity would then supply the British market via subsea high voltage direct current (HVDC) power cables, often referred to as interconnectors.

Policy Exchange sees Icelandic hydro- and geothermal power as base-load power source for UK

On its website, Policy Exchange is described as “an independent, non-partisan educational charity seeking free market and localist solutions to public policy questions”. Furthermore, Policy Exchange is said to be “an educational charity with the mission to develop and promote new policy ideas, which deliver better public services, a stronger society and a more dynamic economy”. Its research is supposed to be “evidence-based and strictly empirical”.

HVDC-Interconnectors-Report-Policy-Exchange-UK-2014-1

Unfortunately, it seems that the think tank has somewhat misunderstood the facts, advantages and possibilities of the Icelandic energy resources. In its report mentioned above, Policy Exchange claims that an “interconnector to Iceland would […] be an import-only connection, which would bring base-load Icelandic hydro and geothermal power to the GB market.” According to the report, such an “interconnector, like that to Iceland, which is expected to provide zero-carbon base-load power supply in one direction (i.e. from Iceland to the UK) is most directly in competition with other base-load power sources, such as nuclear power.”

This assumption by Policy Exchange is somewhat inaccurate. It ignores the fact that Iceland’s main source of electricity is hydropower, based on large reservoirs. Although it is true that Iceland’s geothermal- and hydropower resources can be good options for base-load energy, hydropower offers much more valuable characteristics. Here we will explain why an interconnector between UK and Iceland would have considerable better economical (and political) foundations if it is utilized as access to highly flexible renewable power source, rather than base-load energy.

The think tank is not realizing the main advantages of an interconnector to Iceland

The best opportunity offered by a HVDC cable connecting Iceland and UK, is to harness the Icelandic hydropower resources (and reservoirs) for high demand peak load power in the UK – and as energy storage during low power demand in the UK. Icelandic reservoirs are like natural energy batteries, where Icelandic electricity firms can “store” the energy to the exact period when it is most needed. This makes it possible to manage the electricity generation very accurately – and thereby increase or decrease the production with a very short notice in line with changes in the electricity demand. Therefore, hydropower with large reservoirs are excellent system stabilizers. This flexibility or steerability of hydropower also offers possibilities for maximizing the profitability of the electricity production. The result is that utilizing the flexibility of Iceland’s hydro power would be a great benefit to both the UK and Iceland.

HVDC-Interconnectors-Report-Policy-Exchange-UK-2014-3

Steerable hydropower is tremendously important and valuable. The reliable and controllable renewable power source of hydropower from reservoirs is by far the best choice to meet increased (or decreased) electricity demand and balancing the system. This positive feature of hydropower is reflected by the well known concept of pumped hydropower storage, where it makes economical sense to spend electricity on pumping water up to reservoirs. In a nutshell, hydropower plants with large reservoirs can serve as energy storage when electricity demand is low, and when the demand rises it only takes a few moments for the hydropower plant to increase production. This is obviously a very positive feature, such as at peak load times (normally occurring during the day rather than night). It also means that the operator of a hydropower plant can maximize the profitability of the plant by utilizing the flexibility of the plant – by running the plant at full capacity when electricity prices are highest. Therefore, hydropower can be substantially more profitable than other electricity sources.

Having this feature of hydropower in mind, it is quite surprising to see Policy Exchange suggesting to market Icelandic hydropower as base-load energy source. By doing so, Policy Exchange is ignoring the fact that the Icelandic hydropower could create much more value if the business model would focus on peak demand rather than base-load power supply. And this would not only benefit Iceland, but also the UK.

Icelandic hydropower would be an important system stabilizer for the the UK

In its report, Policy Exchange recommended that the interconnector between Iceland and UK should be one way export of electricity from Iceland and be directly in competition with other base-load power sources, such as nuclear power. This suggestion ignores how the flexibility of hydropower stations with large reservoirs (like in Iceland) makes hydropower quite unique and very different from nuclear power (only gas powered generators have the possibility to respond as quickly to changing system conditions as hydroelectric generators). In fact, nuclear power plants must be run at close to full output all of the time – and they actually need capacity liked pumped hydro storage for excess power at times of low demand. Therefore, it is quite obvious that the main advantage for the UK, by the construction of an interconnector between UK and Iceland, is the access to peak load renewable power from Iceland, rather than base-load.

Iceland-Europe-submarine-hvdc-cable_routesThe interconnector between Iceland and the UK should also be in the role of bringing electricity from the UK to Iceland at periods of low demand in the UK. This would maximize the flexibility and steerability of the Icelandic reservoirs, and at the same time increase the opportunities for the UK to stabilize the British electric system. In this case, the Icelandic reservoirs would act as valuable energy storage for the British electricity market. This is especially important as more and more wind power is harnessed in the UK. More wind power will mean increased fluctuation in the electricity system and call for increased access to reliable flexible power source – like Icelandic hydropower.

It will not only be important to export electricity from Iceland to UK. Exporting electricity from UK to Iceland will also benefit both nations. During periods of low power demand in the UK (such as at nighttime), electricity generated by power plants in the UK could be used to fulfill electricity demand in Iceland. At the same time, water flowing from the Icelandic highlands and mountainous areas would be saved in the Icelandic reservoirs. When electricity demand in UK rises in the morning and during the day, the water in the Icelandic reservoirs would be utilized for generating electricity at high capacity to meet the increased demand. The result is that an interconnector between UK and Iceland offers access to valuable and renewable energy storage, ready for peak load demand – at relatively low price. It is even possible that electricity from the UK might be used for pumping water up to the Icelandic reservoirs from downriver during the periods of low electricity demand in the UK – this pumped water would then be available as a increased power source when demand in the UK rises during the day.

Win-win situation

Although Policy Exchange is somewhat inaccurate when it sees Icelandic electricity as basload power, the think tank is correct in its conclusions, when it states that “interconnectors appear to be an attractive option for the British electricity sector”. Policy Exchange is also correct when saying that “British consumers would benefit from importing overseas-generated power which is cheaper than domestic alternatives”. Electricity generated by hydropower (and geothermal power) in Iceland would be less costly for consumers in UK than electricity from for example new wind parks or new nuclear plants. And it is true that an interconnector between UK and Iceland would be “one way of achieving the oft-sought goal in energy policy of diversification of supply” – as Policy Exchange mentions in its report . And such a project would indeed provide both technical and geographic diversification, as the report says.

UK-Policy-Exchange-_Interconnectors-HVDC-Report-Cover-2014In its report, Policy Exchange expresses, that the UK wants more electricity from overseas and that there is no good reason to stand in the way of new interconnectors (“we want their electricity; they want our money”) . This argument is e.g. based on the fact that Icelandic renewable electricity would be available to the Brits for less money than the electricity would cost if it was generated at home (in UK). In addition, an Interconnector between UK and Iceland would offer British consumers access to much more reliable energy sources than for example British wind energy can ever be.

Economically and politically it is highly unlikely that the project will ever be realized if the business model is a one-way base-load interconnector. To create a win-win situation for both UK and Iceland the electricity must be able to flow in both directions, where the cable would have the purpose to meet peak load demand and also offer the possibility to utilize Iceland’s flexible hydrpower system as energy storage. Finally, it is worth mentioning that according to the latest news from ABB the technology for an interconnector between Iceland and UK is available.

Iceland and Greenland as strategic energy storage for peak load demand

In 2004, the engineering giant ABB marked the 50th anniversary of its pioneering of high voltage direct current technology (HVDC). In the decade that has passed since then, we have experienced numerous new world records regarding the HVDC technology. An electric cable between Europe and America is probably becoming a question of when, not if.

Strong HVDC technology advancement

The first submarine HVDC cable was commissioned in 1954. The cable connected the island of Gotland (in the Baltic Sea) with the mainland of Sweden. This was a 100 kV subsea cable with a capacity of 20 MW and the length was 90 km.

HVDC-Europe-Subsea-2014As earlier mentioned, this first HVDC subsea cable was constructed by ABB in 1954. Fifty years later, in 2004, ABB proudly looked back to its HVDC achievements. Which included the highest voltage cable in the world (600 kV cable in Brazil), the longest HVDC line and highest converter power rate (in China), and the world’s longest underground cable (Murray Link in Australia).

Another of ABB’s achievements in its 50 year history of HVDC technology, was the world’s longest submarine electric cable; the 260 km long Baltic Cable between Sweden and Germany, which began operation in 1994. Now, a decade later, ABB still holds the world record of the longest submarine HVDC cable. It was in 2006 that construction started of the 580 km Norned cable between Norway and Netherlands. ABB supplied the main part of the NorNed cable as well as the converter stations at both ends. With 450 kV DC, the NorNed now has the highest voltage rating of all submarine HVDC cables (on pair with two other cables in the Baltic).

The next world-record-length for a submarine HVDC cable will probably be a cable that will connect Norway and the UK. The cable length will be close to or a little more than 700 km. The planned capacity is 1,400 MW (double the capacity of NorNed) and the voltage 500 kV. Yet, this new cable between Norway and UK will not have the highest voltage of all submarine HVDC cables. Currently, Prysmian and Siemens are constructing the first HVDC subsea cable link in the world with a voltage of 600 kV. This project is the the 420 km UK Western Link between Scotland and Wales.

This high voltage of 600 kV helps increase line capacity by 20% and reduces transmission losses by nearly a third. The Western Link will also set a new world record for capacity of subsea HVDC cables, as it will have a transmission capacity of 2,200 MW. It is Siemens that will be delivering the HVDC converter stations, and Prysmian, which will deliver the cable.

Electric cable(s) between Europe and America

The longest electric HVDC cables on land today are 2,000-2,500 km long. (cables in Brazil and China). It is unclear when submarine electric cables will be as long. But it is evident that we will soon experience subsea cables that will be more than 700 km long and operate at more than 600 kV. Predicting further into the future, it seems realistic that the development of the subsea cable technology will reflect what has been happening on land.

HVDC-Europe-America_Hydro-Power_Askja-Energy-Partners-Map-2It is probably just a matter of time until the first electrical cable will be laid across the Atlantic. Cables from Greenland to North America and/ or Europe would be 2,000-3,500 km long. A submarine HVDC cable between Greenland and Iceland could be as short as 800 km. This is a very interesting fact, as Greenland has enormous hydropower resources, that could be utilized as a a peak power source for areas in Europe (where electricity prices are among the highest in the world).

The idea of an electric subsea cable between Europe and America may sound like a fantasy. And it is quite possible that the combined length and depth will stand in the way for such a project. However, as 700 km subsea HVDC cables at 600 kV are becoming a reality, and the deepest subsea electric cables today are already working well at a depth in the range of 1500-1700 m, it seems that cables between Europe and Iceland, Iceland and Greenland, and Greenland and Canada (North America) are all becoming technically possible within a decade or few decades from now.

Renewable-Energy-Integration_Practical-Management-of-Variability-Uncertainty-and-Flexibility-in-Power-Grids_2014Therefore, it is no surprise that it is becoming increasingly more common to see for example articles in international academic journals focusing on the potential of electric cables between Europe and North America. However, in the literature the focus is surprisingly often primarily on the potential of harnessing the wind power (in both Greenland and Iceland). The best opportunity offered by HVDC cables connecting Greenland and/ or Iceland with Canada and/ or Europe, is definitely to utilize the great hydropower resources (and reservoirs) for high demand peak load power. The hydropower is not only a less costly process to generate electricity than wind power; hydropower is also much more reliable and controllable power source than wind. Therefore, the hydropwer has great possibilities for maximizing the profitability of energy production, by producing and selling electricity only at day time when electricity prices are highest and receive more water in the reservoirs at night time.

The total hydropower resources in Greenland are believed to be equivalent to 800 TWh annually. By harnessing only approximately 1-2% of that would be enough supply more than two HVDC cables. Iceland already has a large hydropower sector, based on large reservoirs and modern generating stations, where it is possible to add capacity (turbines) at very low-cost. Thus, Greenland and Iceland could develop a perfect strategic partnership in supplying Europe with peak load energy.

Icelandic hydropower offers great possibilities for the UK

FT-Electricity-2014-1The Financial Times (FT) recently published an interesting story about how electricity suppliers in the UK “struggle to quench business thirst for power”. This article in the FT is an excellent reminder about how important and valuable it is to have access to reliable on-demand power whenever necessary.

Here, we will explain how the flexibility of the Icelandic water reservoirs can be utilized as a source for peak load electricity demand in Europe, and at the same time substantially increase revenues and profits in the Icelandic energy sector. Such a value creation could be a great business opportunity for the steerable Icelandic hydropower.

Access to flexible electricity is extremely important

In most European countries demand for electricity can fluctuate significantly between day and night. The electricity consumption within the day can also fluctuate – sometimes with a very short notice.

As an example, electricity consumption can change suddenly at commercial brakes within popular television broadcasting shows – when tens of thousands of families suddenly put the kettle on and/or the microwave. Such fluctuations in electricity demand are often unforeseen. That’s why most European nations need to have good access to energy sources that offer highly flexible and controllable production.

But not all energy sources offer good possibilities to increase or decrease electricity-production rapidly. It is actually only natural gas-fired stations and hydropower stations with reservoirs that are flexible enough to fulfill the need of stability in the electricity system.

Hydropower and natural gas are the best options for stabilizing the system

Yes – It is a well known fact that when demand for electricity changes significantly and abruptly, it is natural gas fried power plants and hydroelectric power plants (with reservoirs) that have the best capabilities to meet such changes. This both applies to the need of increased or decreased production.

UK-Electricity-typical-weekly-demand_University-of-Glasgow-presentation-2012Response time of coal power plants is much slower. And nuclear power stations offer base load power and must be run at close to full output all of the time (therefore storage capacity is needed for excess power generated by nuclear plants at times of low demand).

Wind power and solar power plants are almost useless in the regard of flexibility. Because they are subject to the present natural forces (the wind and the sun). In fact, increased use of wind and solar energy in Europe has made it even more difficult to control the balance in the electricity system. Hence, the need for flexible and controllable power production has become ever greater as the use of wind and solar energy increases.

Steerable renewable electricity is tremendously valuable

Because of the flexibility of hydropower- and natural gas plants – these are the best energy sources to take advantage of price volatility on the power market. The water reservoirs make it possible to manage the production very accurately – and thereby increase or decrease the electricity production with very short notice in line with changes in the electricity demand. Thus, hydropower plants have excellent possibilities to maximize their revenues and profits with regard to price fluctuations in the electricity market.

This feature makes hydropower quite unique and makes it the energy source that can deliver the highest return on investment. Moreover, hydropower has the advantage over natural gas being a renewable source of energy. Thus, hydropower can be described as the jewel in the electricity sector – at least if the hydropower station has access to a traditional power market where the demand for electricity fluctuates substantially.

Pumped storage is an excellent example of the great value of hydropower

To have a better access to flexible electricity, there are examples of water being pumped up to reservoirs (pumped storage). This same water is utilized for electricity production later, when demand is high. Pumped storage also serves as important factor in load balancing. This kind of electricity production is e.g. well known in Austria and Switzerland, as well as in the United Kingdom.

Obviously substantial amount of energy is needed for the pumping. But as the pumping primarily takes place during night (when electricity demand is minimum and electricity prices are low) and the water from the upper reservoir is used for electricity production when the demand is high (and prices also), this is a viable option.

Countries with extensive hydro resources are in a key position as system stabilizers

Pumped storage is a good example of how hydropower with water reservoirs offers the best opportunity to be in the role of flexible electricity supply. However, possibilities for pumped storage are limited. Thus, large electricity markets can gain tremendously from being connected to even faraway hydropower sources – like if the UK had a connector to Iceland.

LV-Autumn-Meeting-2013-slide-11This is also an interesting option for Iceland. Areas that enjoy substantial opportunities for developing hydropower stations beyond their local market need can take advantage of sudden price changes on fluctuating electricity markets. It is precisely such given flexibility with water reservoirs, that has greatly increased the value of the Norwegian hydropower. The worlds’ longest subsea electric cable today is the NorNed cable between Norway and the Netherlands. And now a cable between Norway and the UK is being planned and also another cable between Norway and continental Europe.

All this is an indicative of how profitable it is for countries with steerable hydropower to have access to electricity markets where electricity demand fluctuates substantially. In this context electricity from hydropower can be described as the most prestigious product in the energy market.

Iceland has one of the worlds’ most flexible power system

Overseas Iceland is quite well known for its geothermal energy. However, geothermal is the source for only 25 per cent of Iceland’s electricity production. It is hydropower that is Iceland’s most important energy source. The country’s mountainous areas and high precipitation create perfect conditions for utilizing hydropower. Large and small reservoirs are like natural energy batteries, where Icelandic electricity firms can “store” the energy to the exact period it is most needed and sold at the highest prices.

LV-Autumn-Meeting-2013-slide-26Iceland is the largest hydroelectric producer in the world per capita (Norway comes in second place). But Iceland has not yet taken advantage of the flexibility of its hydropower. In most other European countries the reservoirs would normally be in the role of highly profitable flexible energy sources. In Iceland, however, the main role of the reservoirs has been to serve as energy reserves available for aluminum smelters, which require access to cheap and highly reliable energy source.

Moreover, the isolated and closed Icelandic electricity market sometimes results in water flowing from full reservoirs by spillway and into sea without creating any value. Such waste of hydropower is like throwing away the most luxurious goods in the energy market.

If Iceland had access to a more normal electricity market (the aluminum industry uses about 75% of all electricity generated in Iceland) it could present Iceland with an unparalleled business opportunity. At the same time, the overseas market linked with Iceland by an interconnector would have substantially increased access to highly reliable flexible renewable energy source. This can truly been described as a win-win situation.

Interconnector between Iceland and Europe may be within reach

Subsea electric cables are steadily becoming longer and going through more depths. A cable between Iceland and Europe (UK) would probably be close to 1,200 m in length and the greatest depth would be close to 1,000 m. Today the longest cable of this kind is close to 600 km and it is likely we will soon see cables extending 700-800 km (a cable between Norway and the UK may become the next record length). And there are already examples of such subsea cables where the sea is more than 1,600 m deep.

LV-Autumn-Meeting-2013-slide-28It seems becoming both technically and financially possible to have an interconnector between Iceland and Europe and at modest cost. The advantages are obvious; both for Iceland and the European country at the other end of the cable. Due to the distance, the UK seems to be the best option. And actually the energy policy of the UK is also very positive for such a project. Thus, an interconnector between Iceland and the UK may be within reach.

In the earlier mentioned article in the FT, it is described how manufacturing companies in the UK are finding it hard to access electricity for their production: “[A]ccording to research by Edison Group, a consultancy, one in four UK midsized companies are planning for power shortages over the next few winters.” This situation is obviously very worrying for the UK and calls for immediate measures to ensure future access to more (stored) power.

This alarming issue for the UK was the subject of an editorial in the FT on last June 10th (2014). We will conclude this article about how the Icelandic hydropower offers great opportunities – for both Iceland and the UK – by quoting this FT editorial:

FT-Electricity-2014-2

Britain’s supply of electricity is dangerously close to resurgent demand. The safety margin of capacity has been shrinking and now stands well below the 20 per cent necessary to insure against shocks. When demand rises in winter there is a risk that the margin will disappear altogether.

To avert this grim possibility, Britain’s National Grid has just announced measures intended to stave off the risk of looming winter blackouts. The regulated utility plans to pay large users of power to be cut off should demand risk outpacing supply. It also intends to recommission about a dozen mothballed gas-fired power plants to establish a capacity reserve. […] The immediate need is to keep the lights burning. National Grid should do whatever it takes to achieve this until new capacity can be commissioned. This will mean higher bills. But house insurance is never cheap when smoke is pouring from one’s windows.

The importance of diversifying Europe’s energy sources

Economist-Euorope-Energy-Security-april-2014-3The Economist recently wrote about how Europe is highly vulnerable to Russian control over gas supplies – and how Europe can reduce its reliance on Russia by changing generating technology. In the article, it states that “better electricity interconnectors could reduce that need for gas by making it easier to export electricity from renewables-rich markets like Germany on sunny or windy days and to import it on dark or still ones.“ This brings attention to the great importance of strengthening the electric grid in Europe and construct new electric cables, such as to Norway and to Iceland.

The Economist correctly points out that interconnectors can help substitute one type of renewable energy for another. Hydropower (like gas-fired power stations) can easily be turned on – when the wind in Germany or United Kingdom  falters. But hydropower is not evenly spread. As stated in the article, “Sweden and, particularly, Norway have a lot of it, Germany and Benelux not so much.” Iceland is a country with abundant hydropower, that by far exceeds the country’s own electricity needs. In addition, Iceland also has extensive geothermal resources, that offer stable electricity generation for domestic use and for exports via submarine electric cable(s). Thus, Icelandic energy can be an excellent option for diversifying Europe’s energy sources.

Icelink-Bloomberg-HVDC-2“Forging such links requires a pan-European push”, the Economist-article continues. To make it work on a large scale will require new pricing strategies to recompense the owners of fossil-fuel plants pushed off the grid when renewable energy from other countries flows in. According to the Economist, Norway could generate much more hydropower, given a market. The Economist states that there are currently plans for up to five new interconnectors from Norway to the EU to be built by 2020, with a capacity of up to 5GW. An inteconnector to Iceland would easily offer 1 GW more.

In last March (2014) the EU’s Heads of Government told the EU Commission to produce a plan for reducing energy dependence. The plan is to be finalized by June, and some of the key elements of the strategy are to include an in-depth study of EU energy security and plan for the diversification of supply. That is likely to give a push to storage capacity and both more and larger interconnectors. Iceland is the world’s number one electricity generator per capita and still has substantial unharnessed hydro- and geothermal resources. Thus, the development and implementation of such an action plan may offer very interesting possibilities for the Icelandic energy sector.

Feasibility of IceLink (Iceland-UK interconnector)

The Icelandic Energy Portal is cooperating with the University of Iceland and Reykjavik University, as scientific and educational partners. Thus, we sometimes introduce research by university scholars and students. Today, we will focus on the findings in a recent thesis towards MSc in Sustainable Energy at Reykjavik University, by Mr. Randall Morgan Greene.

HR-RU-WelcomeThe title of the thesis is “Iceland-UK Interconnector: Strategy for Macroeconomic and Legal Feasibility”. According to the thesis, the UK must undertake drastic changes in their energy system if they are to achieve energy policy goals of competitive electricity prices, ensuring security of supply, and decarbonization of generation. Interconnection with Iceland, which is dominated by renewable energy, could offer an enticing, cost-competitive alternative to building new low-carbon generation in the UK and carries the potential for positive economic and technical benefits for both countries.

However, the author points out that the structure of EU and UK electricity systems and legislation places some blockades in this project attaining legal and macroeconomic feasibility. While there is some regulatory uncertainty associated with it, there is a potential that the status quo merchant interconnection investment model could be applied to the Iceland-UK in order to attain the aforementioned feasibility – especially if there is a potential for the application of the emerging legal precedent and business model framework in the Imera/ElecLink merchant interconnection exemption request (at this stage the concept of ElecLink seem to be advancing faster).

LV-HVDC-Iceland-UK-London-august-2012-1The macroeconomic feasibility of this framework could potentially be strengthened if there is a possibility to apply the UKs new Feed-in-Tariffs with Contract-for-Difference (FiT CfD) to generators in Iceland. The Imera/ElecLink framework adequately covers investor concerns over stable, long term returns while satisfactorily addressing regulator concerns over competition and third-party access rules for transmission assets. When combined with the FiT CfD program, there is a strong potential that this project can attain macroeconomic feasibility while still being feasible under EU energy legislation.

However, due to the ElecLink exemption not being due till spring 2014 and there being no clear precedent concerning the application of the UKs FiT CfD program to non-UK generators, this potential still requires more in-depth investigation.

UK is looking to Iceland for electricity

In last March (2014), UK’s National Grid published a new paper exploring the potential benefits of greater electricity interconnection. According to the paper, new interconnectors will have positive economic and environmental effects. The benefits include lower energy prices for consumers, enhanced energy security, a cleaner environment and wider macro-economic effects. National Grid believes that a full understanding of the benefits of greater interconnection is important to inform the debate on an appropriate ambition to meet the country’s need, and the timeframe within which it should be achieved

UK_National-Grid-Interconnectors-fig4-march-2014The debate on how the United Kingdom (UK) can best meet its energy needs has intensified over recent months. There is broad agreement that energy should be affordable, greenhouse gas emissions need to be reduced, and energy supplies need to be reliable for businesses and consumers to facilitate the UK’s economic recovery. Despite these benefits, Britain’s 4 GW of existing interconnector capacity is relatively small; representing around 5%of total installed electricity generating capacity. This compares with the benchmark highlighted by the European Commission in January 2014 for all EU Member States to have a level of electricity interconnection equivalent to at least 10% of theirinstalled production capacity to realize the full benefits of the Internal Energy Market.

In order to reach this benchmark Britain would need to double its existing interconnector capacity.Britain is therefore poised to complete the final design elements of the new regulatory regime, enabling developers to secure the considerable capital required to deliver these complex and technically challenging projects. Through continuing to work together, the above stakeholders are now well placed to build on the successful momentum developed to date, to secure the necessary regulatory and investment decisions for a 4-5 GW portfolio of new links in 2014/2015 and unlock the benefits including a GBP 1 billion wholesale electricity price reduction per year by 2020.

UK_National-Grid-Interconnectors-fig3-march-2014As renewable electricity forms an increasing part of the energy mix, interconnection is becoming an important tool in managing the intermittent power flows associated with these sources. Based on the consumer, energy security, environmental and economic benefits which could be accessed, greater GB electricity interconnection is considered a ‘no regrets’ investment by a wide range of informed stakeholders within the UK and beyond. This consensus includes the UK Government, the regulator, consumer organizations, green groups, think tanks, academics and the main European Union institutions.

An interconnector between UK and Iceland (sometimes referred to as the IceLink) could become an important part of the additional interconnection. UK already has four interconnectors to France, Holland, Ireland, and Northern Ireland. These links, with a total capacity of 4 GW, represent around 5% of the existing electricity generation capacity in the UK. However, this level remains low compared to the 10% benchmark proposed by the EU Commission and there is strong consensus that this gap should be filled.

While GB remains a net importer of power, economic benefits are available through greater disposable income from lower domestic electricity prices, and enhanced competitiveness for businesses benefitting from reduced energy input costs. Were a portfolio of new projects to be commissioned, the economy would also benefit from new jobs created in activities such as planning, construction and maintenance. They could also catalyse new domestic manufacturing industries in areas such as sub-sea cabling.

Electric interconnectors allow low carbon electricity to flow between European countries more easily and could enable carbon and renewables targets to be met more cost effectively. Significant volumes of low carbon electricity could, for instance, be imported into UK from hydropower in Norway, wind power in Ireland and Denmark, nuclear in France and hydropower / geothermal energy in Iceland.

New electric interconnector: Sweden-Germany

On March 27th 2014, plans for one more electric cable connecting the European mainland with the Nordic countries were revealed. The plans involve a new high voltage interconnector between Sweden and Germany. The interconnector is called Hansa PowerBridge.

Svenska-kraftnat-logoThis took place at the Annual Stakeholder Meeting of the Swedish National Grid (Svenska kraftnät) in Stockholm. The day after (March 28th 2014), Mr. Mikael Odenberg, CEO of Svenska kraftnät, and Mr. Boris Schucht, CEO the German Transmission System Operator 50Hertz, signed a Memorandum of Understanding (MOU) at the German Embassy in Stockholm. The signing was made in the presence of Mr. Rainer Baake, German State Secretary at the Ministry for Economics and Energy and Mr. Christian Pegel, Minister for Energy in Mecklenburg-Vorpommern.

50hertz-logoAccording to a press release from 50Hertz and Svenska kraftnät, the main objective under the MOU is to examine the feasibility for such a new link between Sweden and Germany. In a joint statement from the companies, such an interconnector is said to be another step towards a better integrated European grid and will allow for increased electricity trade between Germany and Sweden and contribute to the security of supply.

Such a new interconnector between Germany and Sweden is believed to make sense both from a commercial and from an environmental point of view. It links directly the huge storage potentials in Sweden to the wind electricity production centres in Northeastern Germany, thus creating value for both partners. The new interconnector is intended to be put into operation within the next decade. This is one more interesting project to have in mind, regarding the possible interconnector between Iceland and Europe.
