SECI launches tender for 1.2 GW of solar with 600 MW/3,600 MWh of storage
Solar Energy Corp. of India (SECI) has launched a tender for 1.2 GW of solar projects connected to India’s interstate transmission system (ISTS), integrated with 600 MW/3,600 MWh of energy storage systems on a build-own-operate (BOO) basis. Bidding closes Aug. 20.
ZGR battery system kept one Spanish village powered during major Iberian blackout
A 160 kW / 250 kWh standalone battery system installed by Spanish manufacturer Zigor Corporación ensured uninterrupted power for the village of San Vicente del Monte during a major blackout that affected the Iberian Peninsula on 28 April 2025. The system, connected to the low-voltage (400 V) grid, supplied electricity to the entire village for more than five hours.
Canada invests in Indigenous-led 2.85 MW solar project
The Sādę Solar Initiative will connect a solar array and battery energy storage to an existing microgrid located within the asserted traditional territory of the Liard First Nation.
UGT Renewables to build 3 GW of solar in Iraq
UGT Renewables, a US-based developer, says it will build a 3 GW solar project in Iraq under a deal with the federal government that includes 500 MWh of storage and 1,000 km of high-voltage direct current (HVDC) lines.
Comparing thermal runaway behavior of sodium-ion, lithium-ion batteries
Scientists in Germany have analyzed the thermal runaway behavior of sodium-ion batteries and lithium-ion batteries inside a 10-L reaction vessel. They have thermally abused 30 samples, each under a different state of charge level, and have found that both types suffered from runaway when the charge is at least 50%.
Daikin launches new single-zone heat pumps for residential use
The new Oterra 115V heat pumps use difluoromethane (R32) as the refrigerant and have a heating capacity of 9,000 BTU/h to 12,000 BTU/h.
Hungary’s largest battery storage facility comes online
MET Group has switched on Hungary’s largest battery, a 40 MW/80 MWh system, at the site of a power station near Budapest.
Hungary’s solar capacity nears 8 GW
Data from transmission system operator MAVIR shows that solar energy production in Hungary reached a new peak on June 13, producing enough energy to serve the country’s domestic electricity requirements entirely from renewables.
The Hydrogen Stream: Mitsubishi Power completes hydrogen blending project
Georgia Power and Mitsubishi Power have completed a 50% hydrogen fuel blend trial on an advanced-class gas turbine at Plant McDonough-Atkinson in the US state of Georgia, while Proteus Energy and Symbio France have developed a modular 75 kW hydrogen fuel cell system for hybrid and harbor vessels.
