Stem Inc and Sunverge, best known for providing battery and solar-plus-storage solutions for businesses and homes respectively, are partnering with companies in the electric vehicle (EV) sector. 

India’s biggest grid-scale battery storage system to date received a visit from Delhi government minister Satyendar Jain, who emphasised the urgent need for energy storage to stabilise the grid and incorporate higher shares of renewable energy sources. 

This edition of news in brief from around the world in energy storage focuses on small-scale but potentially significant deployments. 

Wärtsilä will deploy a 5.2MW / 5.2MWh energy storage system (ESS) to help support Taiwan’s grid, joining the frequency regulation market launched this year by state-owned utility Taiwan Power Company (Taipower). 

Updated 27 July 2021: An RWE spokesperson told Energy-Storage.news that the combined capacity of the BESS installations will be 128MWh across the two sites. It was also confirmed that the project will be commercially-oriented, rather than a demonstration of the technology or potential business models.

The Solar Energy Corporation of India (SECI) has said that it will launch a tender for 2,000MWh of standalone energy storage systems (ESS).

The acquisition of a 60.5% stake in ENGIE EPS by Taiwan Cement Corporation (TCC) was finalised and completed earlier this week.

Powin Energy has installed battery energy storage systems (BESS) in Israel and Taiwan which, while small by comparison to some of the company’s recent US projects, mark entry into new territories for the Oregon-headquartered system integrator.

A group of eight transmission system operators (TSOs) across Europe have launched a joint initiative to highlight and develop the role that the grid plays in enabling decarbonisation targets to be met.

By the end of 2022, the volume of installed batteries in the UK is set to outstrip the demand from frequency services, marking a key tipping point for Dynamic Containment (DC).
