Econergy Commissions 70 MW/141 MWh Merchant BESS
Romania has officially surpassed the 1 GW milestone for utility-scale battery energy storage capacity, marking a significant boom in the country's flexibility market. Leading this charge, renewable developer Econergy has placed a fully merchant 70 MW/141 MWh battery into commercial operation alongside its Părău 1 solar plant in Brașov county. The €85 million investment brings the combined site capacity to 162 MW, complementing the existing 92 MW solar array.
Strategic Grid Utilization and Merchant Arbitrage
The Părău project highlights a growing trend in Romania where developers optimize existing grid connections by integrating batteries into operational solar sites. This strategy maximizes the commercial value of the grid asset and allows generators to shift output away from crowded midday hours. Operating on a merchant basis, the BESS features dedicated grid-import capacity, enabling it to charge during low or negative-price periods and capture clipped solar generation.
"Econergy reported €21.34 million in costs for the Părău 1 BESS project, expecting €9.74 million in revenue from storage and a return on capital outlay investment of just over three years based on Funds From Operations."
Broader Market Expansion and Public Funding
Econergy's domestic battery pipeline in Romania now totals 521 MW and over 1 GWh, including proposed capacity at Rătești, Oradea, and Ovidiu. Furthermore, the company secured €229 million in EBRD-backed financing for the Părău 2 project, pairing a 342 MW solar plant with a 150 MW battery system. This private momentum is matched by robust public support; the Romanian government is launching two funding programs totaling €650 million from the EU Modernization Fund for solar PV and battery storage at public institutions, mandating 2 to 4 hours of storage for new installations.
