Notice re. Status of Genesee Re-Powering Project and Genesee Units 1 (GN1) and 2 (GN2)

Updated June 29, 2023

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).

• On December 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.
• GN1 will take a planned outage, the timing of which will be communicated on the monthly and daily outage page per normal course of business. The GN1 asset ID will be retired shortly thereafter.
• On April 3, 2024, Capital Power plans to begin an outage of GNR1 to tie-in the refurbished GN1 steam turbine asset.
• On April 17, 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. (See note)

The re-powering of Genesee Unit 2 will approximately reflect the re-powering of Unit 1:

• On March 15, 2024, Capital Power plans to connect a new gas turbine as asset ID GNR2. The MC of GNR2 will initially be 411 MW.
• GN2 will take a planned outage, the timing of which will be communicated on the monthly and daily outage page per normal course of business. The GN2 asset ID will be retired shortly thereafter.
• On June 2, 2024, Capital Power plans to begin an outage of GNR2 to tie-in the refurbished GN2 steam turbine asset.
• On June 16, 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. (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 current functional specification for GNR1 and GNR2, approved by the AESO on May 27, 2022, 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 revised in the future.
