Dear Editor:
RE: ‘Not willing’ hosts, Dec. 5.
This raised concerns regarding a proposed 210 MW battery energy storage system (BESS) in Centre Wellington.
Energy storage systems, specifically utility-scale BESS facilities, are proposed in several Ontario municipalities as part of an ongoing procurement by the province’s Independent Electricity System Operator. The procurement aims to meet the predicted 75% increase in electricity demand expected by 2050. Meeting the increased demand will require development at a scale not seen in Ontario in a generation and will need a range of storage technologies, including BESS installations.
Energy storage resources are optimizers, ensuring all generation assets in the system are used as efficiently as possible. Storage can take inexpensive energy from the system when it isn’t needed and gives it back to the system at low cost when demand is high, increasing reliability and affordability of electricity for ratepayers. Additionally, BESS specifically can be rapidly deployed, easily scaled, and respond quickly to an electricity grid’s variable needs throughout the system’s expansion.
Regarding the safety concerns expressed in the initial letter, none of the extensive testing or incident data recorded to date has indicated the release of toxic gas or any public safety risks. The application of water on site is not considered best practice, preserving water supply and the water table. In addition, energy storage resources have a smaller geographical footprint than many low-carbon or renewable resources, and often a less permanent one. BESS can be installed on skids or other movable infrastructure, enabling the land to be returned to its previous state and use at the end of the asset’s lifecycle.
Like all electricity grid assets, BESS is a highly regulated resource, subject to meeting the requirements of Canada’s electrical code and applicable provincial codes. Manufacturers adhere to internationally recognized standards developed by the Underwriters Laboratory, which are the basis for Canada’s code standards.
In addition, project developers work closely with local emergency responders to develop a site-specific emergency response plan tailored to the responders and needs of the local community. Developers often offer specialized training or resources to local emergency responders, in line with best practice and guidelines provided Ontario’s Association of Fire Chiefs.
At Energy Storage Canada, we understand BESS, and energy storage broadly, are new to Ontario’s electricity grid and its communities, meaning transparent conversations between developers, municipalities and residents is critical in their implementation.
We’re always happy to join the conversation about energy storage and the role it can play in Canada’s future grids, so please don’t hesitate to reach out if you’d like to talk more about BESS or any other storage-related topics.
