International Power Supply (IPS) has officially opened its new battery energy storage system (BESS) manufacturing facility near Sofia, Bulgaria – a site recognized by the European Commission as a Strategic Project under the Net-Zero Industry Act. . The manufacturing facility has launched with 3 GWh annual capacity, set to expand to 5 GWh by Q2 2026. It is the first gigafactory in Bulgaria for battery energy storage systems (BESS). The plant will deliver 8. 2 MWh X-BESS modules using over 70% European components. International Power Supply (IPS) has officially. . WARSAW (ICIS)–To address rapidly growing demand for energy storage, International Power Supply (IPS) is set to officially open a new automated manufacturing facility of industrial and utility scale batteries in Bulgaria in September, Mariyana Yaneva, CEO at IPS, told ICIS in an exclusive interview. This initiative aims to meet the rising demand for turnkey. .

Energy storage mitigates renewable energy curtailment by absorbing excess electricity generated during periods of high renewable output and low demand or grid constraints, then releasing it when demand is higher or grid capacity is available. . As the penetration of variable renewable energy increases, curtailment of solar PV generation will only increase. Since curtailment will almost always be cheaper than investing in new transmission capacity or new grid-scale storage, curtailed energy should be rewarded, so that PV investment. . curtailment is emerging as a common challenge facing a growing number of power systems. At its core, curtailment is a symptom of an insuficiently flexible power system. This reduces the need to limit renewable generation. .
