Green Flexibility to develop 80 MWh battery for German grid project
Grid companies LEW Verteilnetz and Bayernwerk have launched a pilot project to feed renewable energy into the electricity network in a more grid-friendly manner. One of the energy storage sites to be used in the project will come from Green Flexibility.
Ukraine’s ‘twin cities’ project funds solar for community energy resilience
The Ukrainian government is launching a €2 million ($2.3 million) pilot project with the municipality of Grafenwörth, Austria, to expand solar infrastructure and enhance local energy resilience.
UK government mandates solar panels for new homes in England
Future Homes Standard to include solar panel mandate for new homes, UK government confirms. New building regulations are expected to make PV a requirement for almost all homes, with only “rare exceptions” where impact would be negligible, according to UK Energy Secretary Ed Miliband.
Sungrow unveils PowerTitan 3.0 BESS with 684 Ah cell, silicon carbide PCS
Sungrow has launched the PowerTitan 3.0 battery energy storage system (BESS), built around a 684 Ah cell and a fully liquid-cooled silicon carbide power conversion system.
Rooftop PV may ‘unintentionally’ exacerbate urban heat
New research from Hong Kong confirms that rooftop PV systems significantly contribute raise daytime temperatures in urban environments. The scientists explained that, although their findings highlight important urban resilience considerations, they should not detract from the broader benefits of PV systems for energy sustainability and carbon reduction.
Deakin University launches virtual energy network trial for solar trading
Researchers at Deakin University have launched a first-of-its-kind project exploring how Australian households and small businesses with solar and or battery systems can sell their excess clean energy to others without the technology.
Tata Power hits 4 GW of solar module production capacity
Tata Power’s PV module subsidiary, TP Solar, has produced more than 4 GW of solar panels and 1.4 GW of cells at its factory in Tamil Nadu, India.
Liquid insulation for sustainable transformers
Liquid insulation is one of the ways of ensuring transformers – which convert electric power from high voltages to lower voltages – remain safe. Mineral oil, however, has been the main insulating liquid in industrial power systems to date and sustanaible alternatives are strongly needed.
Cyprus curtails more than half of renewables, including residential solar
Cyprus curtailed more than half of its potential renewable power in early 2025, including record residential solar cuts, as grid limits and a lack of storage strain its energy transition. Without swift investment in flexibility, analysts warn the country risks eroding public trust and delaying decarbonization.
