Energy Storage

Solar Energy Corp. of India (SECI) has started accepting proposals to set up 1 GW/2 GWh of standalone battery energy storage systems (BESS) connected to India’s interstate transmission system (ISTS). Bidding closes on Aug. 5.

The Bulgarian Ministry of Energy is readying to launch a tender on September 2 and provide Capex support for the construction and commissioning of 3 GWh of standalone energy storage facilities. The public call is for projects equal to or greater than 10 MW with at least two hours of storage capacity, which will be primarily used in the frequency regulation markets.

The Generali Group company has signed an agreement to acquire a minority share of Enel Libra Flexsys, which aims to roll out 1.7 GW of battery energy storage projects in Italy. “Revenues are fully contracted for 15 years through capacity agreements with Enel as well as capacity payments from Enel that are backed by Terna, Italy’s transmission system operator,” Sosteneo says.

Chinese battery manufacturer CATL is expanding its presence in the Middle East and Europe via a 4 GWh long-term supply agreement with Israeli integrator BLEnergy.

The Happurg pumped storage plant was shut down in 2011 for safety reasons after the base of the upper reservoir was damaged. Uniper has carried out feasibility studies on the site, with a view to reconnecting it to the grid in 2028. The facility can store approximately 850 MWh of electricity in the form of pumped water.

At Intersolar Europe 2024, ESS News spoke with George Hilton, research and analysis manager at S&P Global, about the state of play in the battery energy storage supply chain and falling prices. According to Hilton, the overcapacity at every level of the supply chain has led to prices that are no longer sustainable for many market players. Meanwhile, technological innovation has led to an unprecedented variety of battery storage technologies on offer, and for a great number of markets the right time to jump in is now.

The Chinese company says its new product has a storage capacity of 2,240 Wh and an expected lifespan of 6,000 cycles.

Dutch developer Lion Storage has secured an irrevocable building permit for its 364 MW/1457 MWh battery energy storage project located in the Vlissingen port, in the southwestern Netherlands.

Rolls-Royce has started developing a hydrogen combustion engine for combined heat and power (CHP) systems in Germany, while Lhyfe has installed a 1 MW electrolyzer for Deutsche Bahn.

A new report by SolarPower Europe finds that more renewables, electrification and flexibility can boost European competitiveness, slashing average day-ahead energy prices by a quarter in the next six years and a third by 2040.
