The State of Qatar has begun a pilot project to store grid-scale power using a 1MW/4MWh lithium-ion energy storage system— a first for the state that relies completely on power from gas and oil.
[pdf] Battery storage prices have gone down a lot since 2010. In 2025, they are about $200–$400 per kWh. This is because of new lithium battery chemistries. Different places have different energy storage costs. China’s average is $101 per kWh. The US average is $236 per kWh.
[pdf] This new World Bank project will finance the necessary grid investment and Botswana’s first 50MW utility-scale battery energy storage system to enable the first wave of renewable energy generation to be smoothly integrated and managed in the grid.
[pdf] Transnistria's storage systems combine lithium-ion batteries with something you wouldn't expect - repurposed electric vehicle (EV) batteries from Western Europe. Wait, no. actually, they're using new LiFePO4 (lithium iron phosphate) cells specifically designed for stationary storage.
[pdf] In order to promote the rapid development of pumped storage, meet the needs of new power system construction and large-scale and high proportion of new energy development, and help achieve the goal of carbon peak and carbon neutrality, the National Energy Administration recently issued the "Pumped Storage Medium and Long Term Development Plan (2021-2035)" (hereinafter referred to as the Plan).
[pdf] • • • • China has completed the Fengning Pumped Storage Power Station in Hebei province, now the largest facility of its kind globally. The plant, which has a total installed capacity of 3.6GW, is operated by the State Grid Corporation of China (SGCC).
