Relevant questions and responses related to the WFEC 2023 RFP for SPP Power Supply Resources will be posted on this page.
Yes, as long as they are relevant to the RFP.
Responses to questions will be provided as soon as practical. Response times will vary depending upon the complexity of the question.
Please submit separate forms for each individual project and each design.
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.
This RFP is for wholesale power supply needs.
In the evaluation of the Proposal, WFEC will evaluate the merits of the project on both a Deliverable and Firm SPP Capacity basis.
In the evaluation of the Proposal, WFEC will evaluate the merits of the project on both a Deliverable and Firm SPP Capacity basis.
All bids must have their components delivered to a point within SPP.
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.
Preference will be given to proposals that provide WFEC with the greatest economic, reliability, or strategic benefits.
Not at this time. Delivery preferences are stated in the RFP.
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.
Not at this time. Delivery preferences are stated in the RFP.
Projects located within the systems of WFEC’s Members will be evaluated provided they meet the criteria specified in the RFP. WFEC Member’s control and govern their own systems which may add an additional considerations in evaluations.
The 300MW maximum is generally the maximum amount of accredited capacity. In this example, the 200MW wind and 200MW PV hybrid project would be acceptable.
WFEC will consider projects in Oklahoma and in the SPP region. Preference will be given to proposals that provide WFEC with the greatest economic, reliability, or strategic benefits.
Projects connected to a distribution system will be evaluated provided they meet the criteria specified in the RFP. This may add an additional considerations in evaluations.
Yes. Additional battery duration could be favorable. 4 hour min.
Yes. 50 MW is the minimum.
The “Min Capacity Guarantee” is the “floor quantity” that the bidder will guarantee the offer provides in MWs of capacity throughout the term of the offer.
It is a percentage of a theoretical resource providing full output for every hour of the year. E.g. 100 MW unit x 8,760 hours in year = 876,000 MWh. A 90% availability guarantee would guarantee the resoruce was available to produce 788,400 MWh (90%).
A bid fee is not required to participate in the RFP.
The scoring criteria for this RFP is confidential. The evaluation material can be found in section 3.2 of the RFP document.
Bidders can provide information on interconnection plans, there is not a specific threshold requirement.
No, preference will be given to proposals that provide WFEC with the greatest economic, reliability, or strategic benefits.
Any storage component (MW) of an offer can be made, but 4 hour storage components are preferred. The optimal storage to be co-located will depend on items like the expected output of the main resource, and the overall economic, reliability, or strategic benefits. Include your reasoning for your choice of size of co-located storage.
Preference will be given to proposals that provide WFEC with the greatest economic, reliability, or strategic benefits. The RFP includes specific preferred and minimum terms for specific power supply resource types.
Grid charging is acceptable and expected when it presents the optimal opportunity for WFEC. Storage resources should not include any costs of charging energy or revenue from discharging energy in their offer.
This would be discussed in contract negotiations with shortlisted bidders. WFEC prefers terms that provide the most protection for WFEC.
There is no template other than what is provided in the RFP and the appendices. During the Execution of Power Supply Agreements phase of this RFP a Non-Disclosure Agreement and a Draft Purchase Power Agreement and other agreements may be discussed.
Yes. Please submit separate forms for each individual project and each design. Indicate if projects are mutually exclusive with other offers.
Evaluation criteria will be based on the greatest economic, reliability, or strategic benefits. Any additional evaluation criteria will be confidential.
