Napanee Battery Energy Storage System Phase 2
Atura Power, a subsidiary of Ontario Power Generation (OPG), is planning to construct the Napanee Battery Energy Storage System Phase 2 (also known as Napanee BESS Phase 2), an electricity storage facility in the Town of Greater Napanee, Ont., located north of the Lake Ontario shoreline.
The Napanee BESS Phase 2 is part of the proposed Napanee BESS facility that is being developed in two phases. The Napanee BESS Phase 2 project will be located on the same property and directly adjacent to the Napanee BESS Phase 1 project, east of the existing Napanee Generating Station (NGS) in an area previously used for laydown and parking. The Napanee BESS Phase 2 project will be able to store and output up to 265 megawatts (MW) of electricity for up to four hours to Ontario's electricity grid. Phase 1 and Phase 2 will provide up to 500 MW combined.
The Napanee BESS Phase 1 project was previously approved by the Ontario Independent Electricity System Operator (IESO) and an Environmental Assessment is underway for the entire Napanee BESS facility. For more information as well as how to get involved in the Environmental Assessment, please click here.
Atura Power is also planning to expand the electricity generation of its Napanee Generating Station. More information about that project is available here.
Building capacity for Ontario’s electricity grid
After more than a decade of strong supply, Ontario is entering a period of emerging electricity system needs, driven by increasing demand, the refurbishment of existing generating assets, as well as expiring contracts for other electricity-producing facilities.
To prepare for future electricity demands and support a reliable grid for Ontarians, the IESO has initiated a Long-Term Request for Proposals (LT1 RFP) to secure new electricity resources that could be in service by 2027, including energy storage facilities.
The proposed Napanee BESS Phase 2 will increase Ontario’s electricity storage, support grid reliability, and help advance Ontario’s path to a net-zero future.
Environmental permits and approvals, including an Environmental Assessment, will be required to construct this potential project.
Project name: Napanee BESS Phase 2
Location: Town of Greater Napanee, Ont.
Generating technology: Lithium-ion Battery Energy Storage
Nameplate capacity: Up to 265 MW
Public & Indigenous Community Engagement
Atura Power is committed to engaging Indigenous communities, municipalities, and the public, as well as other potentially interested stakeholders throughout this project. The Napanee BESS Phase 2 Public & Indigenous Community Engagement Plan describes the engagement activities that Atura Power will undertake during the LT1 RFP process in accordance with IESO requirement.
Since preparing the engagement plan, we decided to host a second public meeting to provide an additional opportunity to learn about the proposed project. Details are provided below.
We want to hear from you
We invite you to attend our upcoming virtual public community meeting to learn more about the project. This will be the second public meeting for the project, and the materials will be similar as those presented at the first public meeting held on October 18, 2023.
Please access the Contact Us form if you have any questions or accommodation needs. Meeting materials will be available on this webpage following the meeting.
- Napanee BESS Phase 2
If awarded an LT1 contract by the IESO, Atura Power will obtain the necessary permits and approvals prior to construction, including the completion of the Environmental Assessment that commenced in June 2023. Indigenous and stakeholder engagement activities remain a priority and will continue during the next phase of the project.
Project documents will be posted here as they became available. Please let us know if you require an alternate format for any documents posted through the Contact us form below.
