Utility Scale Storage

The Minnesota Public Utilities Commission (PUC) has approved Form Energy’s 10 MW/1 GWh iron-air long-duration storage facility for Xcel Energy.

Germany’s VoltStorage says its containerized 50 kWh vanadium redox flow battery solution can be scaled up to 500 kWh.

Each developer can bid for pumped storage capacities from 200 MW to 2 GW. Projects can be developed at multiple locations, with a minimum project size of 200 MW. The minimum storage cycle is six hours. Bidding closes on August 16.

To increase the share of renewable energy, India needs to introduce demand-side measures like time-of-use tariffs, develop a well-connected national grid, deploy various energy storage options for grid balancing services, and convert its fossil-fuel-powered fleet to operate flexibly.

The Chilean authorities want to contract 5,400 GWh of power from renewable energy, while also including battery storage. The selected developers will secure 20-year power purchase agreements (PPAs).

Serentica Renewables has contracted 1.5 GWh of dedicated six-hour energy storage capacity to provide round-the-clock green energy to its industrial customers.

Australian renewables developer Genex Power has signed agreements with Japanese utility J-Power for a multimillion-dollar funding package that will support the delivery of its 2 GWh pumped hydro project in Queensland Australia, and the development of the 2 GW Bulli Creek solar and battery project.

Africa50 and International Solar Alliance (ISA) will leverage each other’s networks to mobilize funding and raise awareness of African solar projects in European and Indian markets.

China’s Sinopec has switched on the world’s largest solar-to-hydrogen project in Xinjiang, while India has unveiled a new plan to incentivize green hydrogen and electrolyzer production.

Australian renewable energy startup Green Gravity has teamed with underground mining contractor RUC to accelerate the commercialisation of its gravitational energy storage technology which rests on moving weighted objects through disused mine shafts.
