XCEL/SPS - RFP for Deliverable Capacity_1

Southwestern Public Service Company (SPS), an operating company subsidiary of Xcel Energy Inc., is issuing this Request for Proposals (RFP) in solicitation of Deliverable Capacity. The RFP seeks capacity covering the 2027 and 2028 Summer seasons (June through September) and the 2027/28 Winter season (December through March). SPS is focused on seasonal products but will evaluate offers covering longer periods. Proposals should be for a minimum of 25 MW and a maximum of 100 MW, and offered quantities must reflect accredited Deliverable Capacity available to SPS for Planning Reserve Margin compliance, not nameplate or installed capacity.

Bidders may submit one or multiple proposals, but must indicate if proposals are mutually exclusive. Each proposal should specify a fixed monthly charge in $/kW-month for the term. SPS expects to execute any transaction under a WSPP, EEI, or similar agreement; if no existing enabling agreement is in place, a long-form contract will be drafted and subject to agreement by both parties. The seller represents that the offered capacity is not committed to another entity for resource adequacy compliance during the applicable delivery periods. The seller's obligation to deliver the contracted quantity is firm, although the seller may utilize alternative qualifying resources within the Southwest Power Pool (SPP) to satisfy such obligation.

Key dates include the RFP posting date of June 25, 2026. The full RFP document is available for download as a PDF. No other specific deadlines (e.g., proposal due date, Q&A sessions, pre-bid meetings) are provided in the summary. Interested parties are directed to access the full RFP document for complete terms, conditions, and submission instructions.

This procurement is managed through the North American Energy Markets Association (NAEMA), which posted the RFP on behalf of its member Xcel Energy. The RFP is focused on deliverable capacity to meet SPS's resource adequacy requirements within the SPP region.
