WFEC will consider both PPA and BTA structures. Preference will be given to proposals that provide WFEC with the greatest economic, reliability, or strategic benefits. 

Please provide nameplate capacity, ELCC calculation, and output profile (8760 or 12×24). Also, please indicate whether volume is firm or will vary with ELCC changes.

There is no preference, but optimal storage capacity will be calculated depending on the expected hourly output of the renewable generation.

In the evaluation of the Proposal, WFEC will evaluate the merits of the project on both a Deliverable and Firm SPP Capacity basis.

WFEC sees resources located in New Mexico as being better able to meet the State’s current Renewable Portfolio Standard and possible future changes to that standard.

A.) SPP would need to provide that accreditation. The Bidder is expected to include details in their bid on how it proposes to get accreditation.

B.) While WFEC will consider all bids, any “fully registered and transactable” resources are more in keeping with concepts in this RFP.  VPP turnkey system bids should include details such as maintenance of equipment and maintenance of capacity/energy.

The preference is for SPP Firm Capacity proposals which start on June 1, 2025. In the absence of acceptable proposals, WFEC may elect to evaluate SPP Firm Capacity proposals with contract start dates other than June 1, 2025.
