Garza: It will be among the largest battery plants in Southeastern Europe

In a market characterized by significant 15-minute price fluctuations and an increasing number of prosumers, the facility will enhance flexibility, reduce system costs and support the efficient integration of renewable generation, the company underscored.

According to José Garza, Premier Energy Group CEO, the project aligns naturally with its strategy of building a more flexible, integrated electricity platform in Romania.

“Its scale places it among the largest battery plants in Southeastern Europe, and it will support the market by helping to alleviate intraday price volatility, improve grid stability and complement our renewable production and supply activities,” he added.
