Dutch energy storage developer Lion Storage has announced financial close on a battery energy storage system (BESS) it has described as the largest BESS in the Netherlands.

The €350 million ($367 million), 350 MW/1.4 GWh Project Mufasa, at the coastal city of Vlissingen in the southwest Netherlands, will feature 372 of Tesla’s MegaPack 2 XL battery systems, with the US-based company also providing EPC services for the site.

Due to be operational in the first half of 2027, developer Lion said Project Mufasa will operate entirely on a merchant basis, without a fixed electricity offtake contract. The project will, the developer stated, “rely solely on revenues from the various Dutch power markets and the skills and expertise of the project’s leadership team.”
