PSCO - RFP for Firm Capacity and Energy Supply

Public Service Company of Colorado (PSCo) is soliciting proposals for firm capacity and energy supply to meet resource adequacy needs during the summer 2027 period. The RFP, posted on October 8, 2026, seeks supply covering July 1, 2027 through September 30, 2027, though shorter or longer periods (minimum one calendar month) will be considered. Proposals must be for a minimum of 25 MW and a maximum of 200 MW, and PSCo will accept multiple proposals from a single bidder, provided mutually exclusive proposals are identified as such.

Preferred delivery points include Craig, Ault, Ft. Lupton (FLUP), Midway, or Four Corners, with consideration of alternative points. Bidders must specify whether the offered supply relies on firm, conditional firm, or non-firm transmission arrangements, with separate bids requested for non-firm transmission. The seller is responsible for all transmission and ancillary services costs up to the delivery point, while PSCo covers costs at and beyond. Bidders must identify known transmission limitations or curtailment risks that could materially impact delivery.

PSCo expects to execute transactions under the WSPP Firm Schedule C or similar agreement. Successful bidders may be required to provide documentation regarding transmission arrangements and deliverability for resource adequacy purposes, including WRAP. Bidders must specify any fixed monthly charge in $/kW-month. The deadline for proposal submission is not specified in the posted summary; interested parties are directed to the full RFP document linked for complete details.
