Atura Power is proposing to build battery energy storage units adjacent to our Napanee Generating Station and Ontario Power Generation’s Lennox Generating Station.
Need for new electricity resources
Ontario’s electricity system requires at least 4,000 megawatts (MW) of new electricity resources by the end of the decade to maintain reliability for the future. These resources must reliably operate as needed during times of peak system demand. The need is driven by the ongoing refurbishment of Ontario’s nuclear fleet and a growing demand for electricity.
The Independent Electricity System Operator (IESO) is running three procurement processes to secure a total of 4,000 MW of new electricity resources that could be in service by 2027. Atura Power has qualified in IESO’s Expedited Long-Term 1 procurement process and will be submitting a proposal for ~up to 500 MW of battery energy storage to be located at our Napanee Generating Station in Bath, Ontario.
How does battery energy storage work?
Battery energy storage safely stores electrical energy, that is released during periods of high electricity grid demand. The battery is re-charged during periods of low grid demand, often from low emitting renewables (like hydroelectric, wind and solar), that would otherwise be surplus. This ensures that the electricity grid can continue to operate reliably and makes the best use of Ontario’s investments in renewable generation.
Battery energy storage will also help increase local system reliability by providing peak system capacity while reducing CO2 emissions.
The project will include containerized battery and inverter systems, transformers, support buildings, and transmission connection facilities. The proposed battery energy storage units will be located adjacent to Atura Power’s Napanee Generating Station and Ontario Power Generation’s Lennox Generating Station.
Atura Power engaged with Napanee stakeholders on Jan. 12, 2023, and shared information about our battery energy storage plans and sought input.
