Power cables to link UK and Germany to Norway

German renewable energy sources will be linked to Norwegian storage plants via a new sea cable to be completed by 2018, grid operators said on Thursday, while plans for a similar UK cable were also announced.

The high-voltage, direct current cable will form part of a new electricity highway – designed to carry excess wind or solar energy from Germany to Norwegian pump-storage plants.

Germany can only realise ambitious goals for increasing its renewable energy production if electricity can be stored on windy or sunny days for use on cloudy, still days.

But although Germany has impressive wind and solar photovoltaic generation capacity, it has no way of storing excess electricity.

Norway, on the other hand has a large number of pump-storage plants, where excess electricity is used to pump water uphill into high-altitude storage tanks. When energy is needed, the water is released, turning hydroelectric turbines and generating electricity on the way downhill.

The new connection could also be used to bring electricity back to Germany to meet shortfalls in supply, said grid operator firm Tennet.

The Dutch-German operator said the project details – which would see two direct current cables laid between the countries – would be agreed and signed by September.

"The first [cable] should be ready by 2018, as long as all the necessary permits are granted over the coming year and that material and manufacturing capacities are sufficient," said a Tennet spokesman. The second cable should be in operation by 2028.

German Economics Minister Philipp Rösler – who met the Norwegian Minister for Oil and Energy Ola Borten Moe in Berlin before Thursday’s announcement – said he expected the planned energy exchange with Norway to "strengthen the security of supply in Germany and reduce the price of electricity for consumers and businesses."

The connection would also play an important role in Germany's transition from nuclear to renewable energy, said Minister Rösler, helping to "integrate renewable energy" and stabilize the grid.

German state-owned bank KfW will put up 25-30 percent of the costs for the new connection, which will play a vital role in storing Germany's excess energy from renewable sources for a rainy day. The first cable alone will require investments of up to €2 billion.

Tennet has been in discussions with Norwegian grid operator Statnett over the project for more than two years. The Norwegian company, which will be responsible for half of the construction work, also announced plans for a future cable linking Norway to the UK, slated for completion in 2020. 

"Together, the two cables will strengthen the North European electricity grid and the supply security in Norway," Norway's energy department said in a statement.

"The cables will be used for profitable trading of power, meaning electricity will flow to Norway when prices in Germany and the UK are lower than here. In the same way, we will export when prices are high abroad."

Norwegian PM ‘sceptical’ on gas price cap

Norway, which has replaced Russia as Europe's leading supplier of natural gas, said Monday it was 'sceptical' about a gas price cap proposed by a majority of EU members.

Norwegian PM 'sceptical' on gas price cap

“We approach discussions in an open spirit, but we are sceptical of a maximum gas price”, Prime Minister Jonas Gahr Store said in a statement following a phone call with European Commission President Ursula von der Leyen.

“A maximum price does not change the fundamental issue that there is a gas shortage in Europe”, he said.

European energy ministers who met Friday in Brussels said they were in favour of a series of measures aimed at combatting soaring gas and electricity prices, with some calling for a cap on the price of gas imports in the EU.

While the European Commission has proposed a price ceiling on gas imported from Russia, several member states, including Italy, called for a price ceiling on all gas bought by EU states, including liquified natural gas (LNG).

Non-EU member Norway, which has benefitted from soaring prices following Russia’s invasion of Ukraine, has until now kept a low profile on the issue, preferring instead to leave it up to oil and gas companies to negotiate their own contracts.

The Scandinavian country recently replaced Russia as Europe’s leading gas supplier, due to plunging Russian deliveries and an eight percent increase of its own deliveries.

Last week, Norwegian Prime Minister Jonas Gahr Støre told the Financial Times that the country would potentially be open to a price cap and long-term gas agreement to help its European partners.

“I fully understand that Europe now has a profound debate about how energy markets work, how they can secure more affordable prices for citizens, families, industries, and how this shortfall of gas after Putin’s aggression can be handled,” Prime Minister of Norway, Jonas Gahr Støre, told the newspaper.

“Norway is not closing doors to any such discussion,” he added.

However, this weekend he reiterated that it is not the Norwegian government that can directly offer Europe a capped price on gas. He has also moved to clarify that he is open to assessing all the solutions that the EU puts forward, not just price caps and price agreements.

“I tell my European colleagues that it is not me who sells the gas. Licenses are given to companies that pay a high tax, and then they are the ones who sell it,” he told Norwegian newspaper VG this weekend.
