How does the IRP contemplate unit retirements?

The Company completes a 20-year cash flow analysis, under market conditions, focused on coal-fired, biomass-fired, and large CC generation facilities. As directed by the SCC, the Company included unit-specific data in PLEXOS to allow the model to optimize the timing of unit retirements.  

While the VCEA mandates the retirement of carbon-emitting generation by 2045, the Company can petition the SCC for a reliability exception should a given retirement threaten the reliability and security of electric service to customers.
