WindCharger Battery Storage

The WindCharger battery storage facility is located in the Municipal District of Pincher Creek. Alberta.

The facility was Alberta’s first utility-scale lithium-ion battery storage facility. TransAlta has been investigating the viability of battery storage at our various wind farm locations over the past number of years. Our Summerview 2 wind facility location was selected for its many desirable features, which are conducive to sitting a battery storage facility of this nature.

The facility utilizes TESLA battery technology with a nameplate capacity of 10 MW with total storage capacity of 20 megawatt-hours. The Project is situated next to the Summerview 2 substation on previously disturbed lands.

The Project qualified for co-funding from Emissions Reduction Alberta (ERA). ERA works with government, industry, and innovators on projects that reduce greenhouse gas emissions, attract investment, create jobs, and secure Alberta and Canada’ s success in a lower carbon economy.

On November 7, 2019, the Alberta Utilities Commission (AUC) approved TransAlta’ s application to construct and operate the WindCharger battery storage facility at the Summerview substation. The AUC approval was granted under decision 24454-D01-2019.

Construction of the WindCharger battery storage facility began on March 31, 2020 and reached commercial operations on October 15, 2020.
