Notice re. Status of Genesee Re-Powering Project and Genesee Units 1 (GN1) and 2 (GN2)
Pursuant to Section 4 of the Fair, Efficient and Open Competition Regulation, Capital Power has notified the AESO of several outages related to the re-powering of Genesee Unit 1 (GN1) and Unit 2 (GN2) as combined cycle facilities (GNR1 and GNR2).
- The maximum capability for GN2 will increase from 400 MW to 420 MW on October 1, 2022.
- On October 15, 2023, Capital Power plans to connect a new gas turbine as asset ID GNR1. The maximum capability (MC) of GNR1 will initially be 411 MW.
- On November 15, 2023, Capital Power plans to permanently retire asset GN1.
- On February 12, 2024, Capital Power plans to begin an outage of GNR1 to tie-in the former GN1 steam turbine asset.
- On February 27, 2024, GNR1 will return to service for commissioning as a combined cycle unit. The steam turbine formerly operating as GN1 will become part of the GNR1 asset. The MC of GNR1 will become 466 MW. (See note)
The re-powering of Genesee Unit 2 will approximately reflect the re-powering of Unit 1, but delayed by one month:
- On November 15, 2023, Capital Power plans to connect a new gas turbine as asset ID GNR2. The MC of GNR2 will initially be 411 MW.
- On December 15, 2023, Capital Power plans to permanently retire asset GN2.
- On March 12, 2024, Capital Power plans to begin an outage of GNR2 to tie-in the former GN2 steam turbine asset.
- On March 26, 2024, GNR2 will return to service for commissioning as a combined cycle unit. The steam turbine formerly operating as GN2 will become part of the GNR2 asset. The MC of GNR2 will become 466 MW. (See note)
The outage timeline is based on Capital Power’s best estimates at the time of publishing this notice. Dates may change depending on the progress of construction. When necessary, this notice will be updated with revised dates and times provided by Capital Power, as GNR1 and GNR2 will not appear in the AESO’s outage reports until they are connected to the system.
Note: The Maximum Authorized Real Power (MARP) of GNR1 and GNR2 is 466 MW, respectively. This reflects the functional specification approved by the AESO on November 26, 2021, which capped the MC of each asset at 466 MW to reflect the current Most Severe Single Contingency (MSSC) limitation. The MC of these assets may be subject to change, pending the outcome of ongoing consultation on the MSSC.
