Today’s renewable energy news includes announcements on ContourGlobal, Amazon, battery energy storage in Germany, among others.
ContourGlobal Commissions 202-MW Battery at Bulgarian Thermal Power Site
ContourGlobal has inaugurated a 202-MW battery energy storage system (BESS) at the Maritsa East 2 thermal power plant site in Bulgaria, marking one of the country’s largest operational battery projects. The grid-scale facility is designed to enhance system flexibility, provide fast-response balancing services, and support the integration of renewable energy as coal-fired generation is phased down. Installed at an existing power generation location, the battery leverages grid infrastructure already in place, helping reduce development timelines and costs. The project plays a strategic role in strengthening Bulgaria’s power system stability, improving frequency regulation, and enabling a smoother transition toward a cleaner and more resilient energy mix in Southeast Europe.
Amazon Targets Pine Gate’s GW-Scale Solar and Storage Project in Oregon
Amazon is exploring a power offtake from a gigawatt-scale solar and battery storage project being developed by Pine Gate Renewables in Oregon, reinforcing its commitment to sourcing 100 percent renewable energy. The proposed project will combine large-scale solar PV with battery energy storage, enabling reliable, round-the-clock clean power and supporting grid stability in the Pacific Northwest. If secured, the project would rank among Amazon’s largest renewable energy initiatives in the US, helping decarbonise its data centres, logistics operations, and corporate facilities. The development reflects Amazon’s strategy of backing hybrid renewable projects that pair generation with storage to manage intermittency, reduce peak power costs, and accelerate the transition to a low-carbon energy system while driving long-term clean energy investment.
Germany’s Stationary Battery Additions Reach Record 6.6 GWh in 2025
Germany installed a record 6.6 GWh of new stationary battery energy storage capacity in 2025, highlighting the rapid acceleration of energy storage deployment alongside renewable energy growth. The expansion was driven primarily by residential and commercial battery systems paired with rooftop solar, as well as a rising number of large-scale grid batteries supporting system flexibility. Strong policy support, falling battery costs, and increased power price volatility encouraged households, businesses, and utilities to invest in storage solutions. Grid-scale batteries are playing a growing role in balancing intermittent wind and solar generation, reducing curtailment, and enhancing grid stability. The milestone underlines Germany’s position as a leading European market for battery storage and its broader strategy to strengthen energy security while advancing decarbonisation.
