Residential Battery Storage Nears Grid Parity in Germany

It’s very close, according to the German government and some industry observers.


>”It is now generally recognized that rooftop solar has reached “socket parity” — meaning that it is comparable to or cheaper than grid prices — in many countries over the last few years. The big question for consumers and utilities is when socket parity will arrive for solar and battery storage.

[…] Electricity prices are rising and solar PV prices are falling, which means that if battery storage falls to around €0.20 per kilowatt-hour (U.S. $0.27), parity will be achieved.

Australian investment firm Morgans, in an assessment of Brisbane-based battery storage developer Redflow, suggests that that company’s zinc-bromine flow battery may already be commercially economic in Germany, the country that leads the world in terms of household adoption and government support for renewables.

Morgans notes that in Germany, the cost of household grid power is around €0.30 per kilowatt-hour (U.S. $0.40) and that the government is now subsidizing residential energy storage systems that are connected to solar systems.

“Given Germany’s substantial adoption of solar PV…costs for solar power range from €0.10 to €0.15 per kilowatt-hour (half the grid price), so when energy storage costs reach €0.15 to €0.20, this will mean renewable energy costs will be at parity with grid prices,” Morgans concludes.  […]”<
