Tesla ‘WindCharger’, the first grid-wide battery storage in the Canadian province of Alberta, goes live


Energy Storage10 MW / 20 MWh of Tesla megapacks used for Alberta’s first-ever large-scale battery energy storage system kicked into action as TransAlta Renewables announced the project had entered commercial operation.

Called WindCharger, the project’s batteries recharge in about two hours from TransAlta’s 66 MW Summerview II wind farm in the Canadian province. Energy-Storage.news last reported on the project in August when it looked set to go into service that month, TransAlta yesterday said it was successful.

“We would like to thank Tesla for working with us on this exciting project,” said TransAlta Renewables President John Kousinioris.

“Completion of the WindCharger project is an important milestone as we move towards our goal of providing clean, reliable and inexpensive energy solutions to our customers,” said Kousinioris, adding that the technology had “great commercial potential”.

Wind, solar and hydroelectric company TransAlta Renewables purchased the project from electricity generation and distribution company TransAlta Corporation, its majority shareholder. TransAlta will pay a fixed monthly charge for the right to operate and ship the battery to the Alberta market.

A large majority of activity in the Canadian energy storage market has been concentrated in the province of Ontario, although the Alberta Utilities Commission recently approved a solar storage project plus comprising 13, 5 MW of solar PV energy and 8 MW / 8 MWh of battery storage. The commission felt that the project was in the public interest to get started.

A C $ 10 billion (US $ 7.53 billion) infrastructure investment plan unveiled by the National Government of Canada a few weeks ago was warmly welcomed by the Energy Storage Canada trade association for its recognition. explicit support for renewable energy and energy storage projects.
