Today’s renewable energy news includes announcements on DTEK and Octopus Energy, Britain’s Battery Storage Capacity, among others.
DTEK and Octopus Energy Launch €100 Million Solar and Storage Initiative for Ukraine
DTEK and Octopus Energy Group have partnered to establish a joint initiative aimed at raising €100 million to deploy 100 rooftop solar and battery storage projects across Ukraine over the next three years. The program, known as RISE (Resilient Independent Solar Energy), is designed to strengthen Ukraine’s energy resilience and accelerate the transition toward a decentralized renewable energy system. A key innovation of the project is the integration of Octopus Energy’s AI-powered Kraken platform with DTEK’s local energy expertise. The system will enable businesses and public institutions to optimize energy consumption in real time, shift loads during peak demand, store excess solar energy, and sell surplus electricity back to the grid. The initiative comes at a critical time, as around 70 percent of Ukraine’s thermal power generation capacity has been damaged, destroyed, or seized since the full-scale invasion. By promoting distributed solar and battery storage, the project will improve energy security, reduce electricity costs, protect customers from outages, and support long-term decarbonization. The program also demonstrates growing international investment and confidence in Ukraine’s sustainable energy future and economic recovery.
Argentina Receives Strong Interest in 700-MW Battery Storage Tender
Argentina has received a strong response from developers and investors in its 700-MW battery energy storage system (BESS) tender, highlighting growing confidence in the country’s energy storage market. The tender is part of Argentina’s broader strategy to strengthen grid reliability, improve energy security, and support the integration of renewable energy sources into the national electricity network. The large-scale BESS initiative is designed to address grid constraints, enhance system flexibility, and ensure a more stable power supply during periods of peak demand. A key innovation of the program is the deployment of utility-scale battery storage capable of storing excess electricity and delivering it when needed, helping balance supply and demand more efficiently.
Britain’s Battery Storage Capacity Nears 7 GW, Surpassing Nuclear Fleet
Britain’s installed battery energy storage system (BESS) capacity has expanded to nearly 7 GW, exceeding the capacity of the country’s nuclear fleet for the first time, according to the latest Drax Electric Insights report. The milestone highlights the rapid growth of energy storage as a critical component of the UK’s evolving electricity system. Wind power remained the country’s largest source of electricity during the first quarter of 2026, accounting for 38.8 percent of generation, supported by record wind output driven by strong weather conditions. A key innovation behind this growth is the increasing deployment of grid-scale battery storage, which enables renewable energy to be stored and dispatched when demand is highest. Batteries are playing an essential role in balancing the grid, improving flexibility, and supporting the integration of growing volumes of wind and solar power. The expansion delivers significant benefits for consumers and businesses by enhancing energy security, improving grid resilience, and supporting the UK’s net-zero ambitions. With electricity demand expected to rise due to AI-driven data centres and electrification, battery storage is becoming a vital technology for ensuring a reliable, affordable, and sustainable energy future.
