LONDON, June 23 (Reuters) – Independent energy firm NatPower and Tesla said on Tuesday ​they had reached a deal ‌to build 25 gigawatt hours of battery storage in Italy and Britain, the first phase of a project worth up to $5 billion.

Countries ‌across ​Europe are ramping up ⁠battery storage projects ⁠to help balance the rollout of intermittent renewable power capacity.

Under the multiyear agreement, NatPower will use Tesla’s Megapack battery ​storage system.

NatPower will also use Tesla’s trading technology,  which manages when to ⁠buy and sell electricity.

Five ⁠initial projects will be built, ​the first phase of a programme that ​ultimately aims to exceed 100 GWh ‌of storage capacity, at a construction cost of $4 billion to $5 billion, the companies said. They added that revenue will ⁠potentially exceed $15 billion over 20 years.

“The sector has access to technology and capital but still ⁠struggles to ‌deliver infrastructure consistently and within ⁠the required timelines. What we ​have ‌built with Tesla is an ​ecosystem that ⁠enables alignment between capital and execution, and that can be replicated across multiple markets,” said Fabrizio Zago, CEO of NatPower.
