EU installs 27.1 GWh of battery storage in 2025 as utility scale leads
The European Union added 27.1 GWh of battery energy storage capacity in 2025, with utility-scale systems accounting for the majority of new installations as residential storage declined amid lower electricity prices and reduced support schemes, according to a new report from SolarPower Europe.
Netherlands’ 2025 solar additions estimated at 2.08 GW
Provisional estimates from Dutch New Energy Research indicate the Netherlands added 0.54 GW of residential solar and 1.54 GW of C&I and large-scale solar last year, taking the country’s cumulative capacity to just shy of 30 GW.
China adds 315 GW of solar in 2025
China installed a record 315 GW of new solar capacity in 2025, lifting cumulative installed PV capacity to 1.2 TW and pushing non-fossil power sources past thermal generation for the first time.
India curtails 2.3 TWh of solar between May and December 2025
A report by energy think tank Ember finds India’s system operator regularly had to curtail solar generation as an emergency measure to maintain grid security, as other resources were already flexing to their maximum capabilities.
