WHEREAS Battery Electric Storage System (BESS) facilities are an important and growing aspect of clean and efficient energy grids; and
WHEREAS ensuring regulatory clarity will help provide confidence to residents and proponents alike that these facilities are being fairly and properly reviewed; and
WHEREAS according to a 2023 report from the Ontario Energy Board (OEB), a typical electricity customer in Ontario uses roughly 25 kWh of electricity per day; and
WHEREAS based on the size to mega-watt hour (mWh) storage of other modern BESS facilities, a 1 hectare facility could provide 50mWh of storage which could provide power to roughly 2000 typical customers for one day; and
WHEREAS based on the current staff report, there are circumstances in which such a capacity and footprint could be considered an Accessory Use despite the intent of an Accessory Use being that these facilities be intended to provide the power needs of a site and are limited by the supply of the building’s energy loads; and
WHEREAS the proper notification about proposed large scale or principal use BESS facilities to local representatives is an important way to ensure that social license for these facilities can be secured.
THEREFORE BE IT RESOLVED that Document 2 Details of Recommended Zoning By-law Amendment to report ACS2025-PDB-PS-0016 regarding Official Plan and Zoning By-law Amendments for Battery Energy Storage Systems (BESS) be revised by adding the underlined text below to the proposed new Section 91-A entitled “Accessory Battery Energy Storage System (BESS)”, sub-section 1(c)(i):
