A 100MW battery energy storage system just announced in the UK by battery storage developer, owner and operator Zenobe Energy is the first such system to win a long-term contract from the country’s transmission system operator to directly absorb reactive power from the transmission network.

The dynamics of balancing electricity supply and demand on the grid have been deeply affected by the coronavirus pandemic, but it’s certainly not the only reason why the UK’s electricity system operator is introducing a new service called Dynamic Containment. What is it and why is the UK already replacing its firm frequency response (FFR) and other ancillary services?

Microgrid projects on three different continents that include multiple megawatts of battery storage alongside renewable energy have been announced in the past few days from well-known industry players.

The world’s largest vehicle-to-grid (V2G) project has been launched at a north London bus garage.

Large wind turbines have blades that need to be angled correctly to capture the optimum generation opportunity, and ultracapacitor maker Skeleton Technologies believes it has developed the answer.

TERNA, operator of Italy’s electricity transmission system, is set to open up a pilot scheme in which up to 230MW of aggregated nominal capacity including energy storage could supply frequency and voltage services to the grid.

Plans by ScottishPower Renewables to build a 50MW battery next to its Whitelee onshore wind farm have been approved by the Scottish government, with the developer hailing it as a “significant step” towards renewable energy providing the baseload for the grid.

Minnesota electric cooperative Connexus Energy has confirmed recent press reports that it is building 15MW / 30MWh of battery energy storage, while another not-for-profit, Vermont Electric Cooperative, will build a 1.9MW / 5.3MWh system in its service area.

A US state-backed organisation is partnering with the government of Singapore to build and test up to three energy storage systems using a variety of technologies on the island state.

The North American subsidiary of international investor-owned energy supplier E.ON has begun construction on its first energy storage project.
