The energy transition arm of Italy’s Enel Group has started construction on a 20MW/40MWh behind-the-meter battery energy storage system at Imperial Oil’s petrochemical complex in Sarnia, Ontario, which it claims will be the largest in North America.

Behind-the-meter battery storage projects announced last week in California and Ontario will cut electricity costs and carbon emissions for a variety of commercial and industrial (C&I) businesses. 

Between CA$1.5 billion (US$1.12 billion) and $4 billion in electricity system cost savings could be achieved by Ontario’s Independent Electricity System Operator (IESO) by installing 1,000MW of energy storage by 2030, according to a new study commissioned by Energy Storage Canada.

Developer NRStor and technology provider Hydrostor have completed work on a multi-megawatt, commercial, advanced compressed air energy storage (A-CAES) system in Canada.

Ontario’s Independent Electricity System Operator (IESO) is set to launch a demonstration of how solar panels, energy storage and customer-sited demand side response (DSR) can be used to drive down costs of the IESO’s network.

US-based energy storage technology provider Powin Energy has claimed it has a pipeline close to 500MWh of projects under contract, including recent awards totalling 70MWh for customers in North and Central America and in Italy.

Enel X, the innovation and digitalisation arm of European utility Enel, is following up an initial 1MWh commercial and industrial (C&I) energy storage project in Ontario, Canada, with a significantly scaled-up second project.

Leading energy storage provider Powin Energy will be building and installing six energy storage projects at two sites in Ontario, Canada with a total capacity of 12.8MW/52.8MWh.

Lithium-ion energy storage manufacturer Leclanché saw revenue of around CHF28 million (US$28.89 million) through H1 2016, up 65% year-on-year, according to the firm’s interim results for the half year ending 30 June 2016.

Ontario’s Independent Electricity System Operator (IESO) has selected five companies to deliver nine energy storage projects with a total capacity of 16.75MW.
