The 1986 Chernobyl accident was caused by a combination of human error and design flaws, resulting from a safety test gone wrong at the Chernobyl Nuclear Power Plant in Ukraine. The disaster had a profound impact on people's health, with thousands affected and many more killed by radiation exposure. The incident led to a significant shift towards global nuclear safety culture, influencing plans for new nuclear capacity worldwide.

Bobwhite Energy Storage has signed a long-term ESA with the Tennessee Valley Authority for a 225MW/900MWh battery energy storage system (BESS) project in East Tennessee. The project aims to provide renewable energy storage capacity of 900MWh. The project will be developed and operated by Tenaska, an independent power producer affiliate of Bobwhite Energy Storage.

Peru's energy ministry has proposed market-based reforms for complementary electricity services to improve grid stability amid rising solar and wind generation, shifting from an administrative to a competitive model. The reforms aim to provide clear economic signals and allow different technologies to compete for these services. The new regulations would also open participation to new providers, including energy storage systems, and assign charges based on causality.

Botswana has launched a 500 MW solar-plus-storage project in Maun, northeastern Botswana, which will be one of the largest projects of its kind in southern Africa. The project, developed by Okavango Solar under an independent power producer model, will provide 500 MWh of battery energy storage to deploy during peak demand periods. A 30-year power purchase agreement has been signed with the state-owned Botswana Power Corporation.

A U.S. Interregional Transmission Overlay (ITO) could address aging grid infrastructure, surging demand, and renewable integration challenges by using high-capacity technologies like HVDC and 765 kV EHVAC to bridge regional seams and integrate renewable generation across the country. The ITO would face major challenges, including cross-state planning coordination, investment barriers, energy market harmonization, supply chain limitations, and political uncertainties. Implementing an ITO could reduce electric system costs by hundreds of billions of dollars by 2050 through strategic corridor identification, multi-stakeholder oversight, and coordinated regional studies.

A regulator in Ireland has cut grid fees for energy storage units, a move seen as progress toward eliminating dual grid fees and supporting the country's growing energy storage industry. This development is being viewed as positive news for the sector, indicating increased support from regulatory bodies. The change aims to make it more cost-effective for energy storage units to operate on the Irish grid.

Zambia's president, Hakainde Hichilema, launched the country's largest hybrid solar-plus-storage project. The project is the largest in African scale for a hybrid renewable energy system. Zambia has become home to this pioneering initiative.

US battery storage developer Key Capture Energy may be up for sale due to the consideration of "various strategic options" to raise financing. The company's owner is exploring ways to bring in a financial partner, potentially leading to a change in ownership. This move could impact Key Capture Energy's operations and future projects.

Expo ER+ 2026 in Guadalajara highlighted Mexico's accelerating photovoltaic and energy storage market, with over 86 companies participating to showcase the latest developments in international photovoltaic and energy storage industries. Energy storage has become a critical link in the global electricity value chain, and industry experts emphasize that future growth will depend on storage and transmission expansion. The sector is entering a phase of technological maturation and strategic redefinition, driven by digitalization and the need for advanced management systems to meet grid reliability requirements.

Utility companies are seeking a five-year moratorium from FERC to protect themselves from competing in building large transmission projects, despite the fact that this request is not about ensuring affordable electricity for consumers. The proposed moratorium would increase transmission costs by approximately 34% and be passed on to unsuspecting ratepayers. This move is seen as a brazen attempt to avoid competition and potential loss of future profits, rather than addressing the real issue of affordability.
