Solar energy storage and backup system integration

Overview

The integration of energy storage and backup systems is increasingly viewed as a critical component for the viability and efficiency of solar power adoption. Initially, the focus is on residential applications where home backup batteries are presented as an essential step for achieving energy independence. This trend extends to large-scale applications, such as in Romania, where energy storage is becoming vital for photovoltaic projects. By August 2026, Romania’s installed battery energy storage systems (BESS) capacity approached 1,000 MW, helping to narrow the country’s electricity import deficit. In mid-October 2026, HELLENiQ ENERGY announced plans to increase its Romanian energy storage investments, targeting a capacity of at least 500 MW by 2029. Through HELLENiQ Renewables Romania, the group is developing hybrid solar and wind projects and evaluating the addition of battery storage to existing photovoltaic parks, with a potential capacity of 170 MW / 680 MWh. Mihai Darie, Director of HELLENiQ Renewables Romania, noted that hybrid solutions have assisted in obtaining more favorable grid connection conditions regarding costs and timelines. Simultaneously, Turkish investors are expanding their footprint in the Romanian sector. Mesut Güler, Chairman of Enexus Holding and BESCA, reported that approximately 200 MW of solar capacity has been commissioned, with 400 MW under construction. Güler anticipates Turkish investors could eventually control a 40% market share, with projected battery storage investments reaching roughly 4 GW. Related developments include LONGi providing a 50 MWh liquid-cooled battery system for projects in the Titu region, and Beta Enerji securing a contract to supply a 250 MVA transformer for a BESS project. Recent developments in Romania show continued expansion through diverse partnerships. The Renovatio Group and Greenvolt Group are developing the 918 MWh Borzești Energy Storage facility in Bacău county in cooperation with CATL.
