Speaking with Energy-Storage.news in March, Dr. Kai-Philipp Kairies, CEO and co-founder of ACCURE said of the demand for data analytics solutions, “I think the energy storage industry is in this really interesting phase of growing maturity. We’ve got real money flooding in. Funds have their first couple of years of experience with limited portfolios, and now everyone’s scaling up. As you scale up in a maturing industry, operational excellence becomes so much more important.”
He continued, “On the first couple of assets, market conditions were really good, and so you didn’t even have to capture all of the potential value to have a really successful year. In those early years, even if you just caught 90% of that, you were doing well. But now, as more and more players flood the market, margins are compressed, and portfolios grow larger, small changes in your efficiency can yield tens of millions of dollars across these portfolios. These are numbers that are worth looking into.”
In September 2025, BESS developer-operator Terra One raised €150 million (US$177 million) in mezannine financing from Aviva. Law firm Ashurst, which advised Aviva on its investment, said that the deal would enable Terra One to deploy 500MW of BESS in Germany, scheduled to be commissioned by 2028.
