Germany has welcomed the “milestone” installation of the country’s 100,000th grid-connected residential battery energy storage system.
Solar-battery storage projects will become “increasingly important” in pushing ahead with Germany’s energy transition (energiewende) policy, the German Solar Association (BSW) quoted parliamentary state secretary to the federal economic and energy minister, Thomas Barei, as saying.
The latest solar-battery system was installed at a home just outside Berlin.
“Since 2013, battery storage costs have dropped by more than 50%, helping to make the energy transition more affordable,” Barei said. “In addition, storage extends the flexibility options for intelligent load management.”
BSW managing director Carsten Körnig said: “More than half of the photovoltaic system purchasers order a battery storage right away, because they want to achieve a high level of independence and to make a contribution to the energy transition. With this momentum, we will reach the next milestone, 200,000 solar batteries, in just two years.”
Analysis by the Mannheim-based Centre for European Economic Research (ZEW), reported by BEST Battery Briefing last month, showed battery storage systems in Germany would scale new heights over the next decade as renewable energy developers become increasingly reliant on the technology.
