Corre Energy has signed an agreement for offtake, co-development and co-investment with Eneco for Corre Energy’s first compressed air energy storage (CAES) project in Ahaus, Germany.
The agreement will see Eneco acquire a 50 per cent interest in the project, at a consideration to be agreed that will comprise both development capital and construction equity. The transaction also means Eneco will secure the entire storage capacity under a long-term offtake agreement for the first phase project.
The co-development, financing and operating of the Ahaus project will be undertaken by LichtBlick, Eneco’s German subsidiary and one of Germany’s largest green energy suppliers, alongside Corre Energy’s subsidiary, Corre Energy Germany GmbH.
Phase one of the Ahaus project will use the first two of the site’s four existing salt caverns to deploy Corre Energy’s multiday CAES solution to deliver 220MW of compression capacity and 320MW of generation capacity. The first cavern is due to be handed over to Corre Energy in early 2027 and construction of all four caverns is already well underway. “The project benefits from accessing caverns which already have permits in place for construction, greatly de-risking overall project development,” a Corre Energy statement said. “The project is expected to use equipment by Siemens Energy following the launch of a global collaboration with Corre Energy in November 2023.”
Corre Energy secured the Ahaus site following a land and cavern option agreement with Solvay, a multinational chemical company, in June 2023. Located in North Rhine-Westphalia, Germany, the CAES site in Ahaus is well located between increasing offshore wind power production in the north and the significant power consumption regions to the south. It is close to the future national hydrogen backbone grid (H2-Startnetz) and will complement the regional establishment of an industrial scale renewables-based green hydrogen value chain.
Keith McGrane, CEO of Corre Energy, said: “This landmark agreement combines offtake, development and co-investment arrangements to propel our first German project while showcasing the latest demand for our CAES solution. It comes just six months after securing the site in Germany and underscores the ongoing success of our growth strategy. To sign a second deal with Eneco just 12 months on from our first agreement in the Netherlands is a testament to the relationship we’ve forged. By locking in long-term investment partnerships such as in Germany, we are accelerating the commercial development of our portfolio underpinned by long-term offtake arrangements. These arrangements are repeatable across the portfolio and for each project can capture around €1bn of net revenue over the duration of a 15-year offtake agreement.”
Kees-Jan Rameau, COO Integrated Energy of Eneco, added: “Energy storage is essential for the sustainable energy system of the future. It helps us use clean power even when there’s no wind or sun available and we can also help ease congestion on the power grid. We see a bright future for these storage solutions and this second project with Corre Energy helps us get closer to the goals in our One Planet Plan: to be climate neutral in 2035, together with our customers.”
