European grid operator TenneT and Mitsubishi Corp. have signed a letter of intent (LOI) to partner on two more offshore grid connections.
The grid connections, HelWin2 and DolWin2, are both located in the German North Sea and are critically important to the integration of renewable energy – especially offshore wind power – onto the German onshore grid, TenneT says.
Helwin2 and Dolwin2 connect a number of offshore wind farms in the German North Sea to the onshore electricity grid and have a combined total capacity of 1.59 GW. They involve an aggregate investment of approximately 1.7 billion euros and an expected third-party equity stake of around 340 million euros.
According to TenneT, the connections bring enough energy onshore to supply 1.5 million households with renewable energy and are both due to be completed by 2015.
