Submit a Question
Can a pre-bid letter of credit from the Energy RFP be used for the Capacity RFP as well?
No. The forms of pre-bid letter of credit are different for each procurement, therefore each procurement requires a separate pre-bid letter of credit.

What time can binding bids be submitted on Wednesday, May 11, 2011?
The bidding window will be open for submission of binding bids from 10:00 am CPT to 12:00 noon CPT on Wednesday, May 11, 2011.

Please clarify the Performance Assurance requirements as they relate to the Pre-Bid Letter of Credit.
Because delivery will be completed shortly after contract execution for this year's procurement, the Pre-Bid Letter of Credit will serve as Performance Assurance for the Capacity RFP, therefore the Expiration Date is extended to June 14, 2011, which is three business days after the final Receipt Deadline (June 9, 2011), which is ten business days after the final Delivery deadline (May 25, 2011). In the event that a bidder is not selected as a winning supplier, the Pre-Bid Letter of Credit can be returned following the ICC ruling on the procurement results.

Which Capacity RFP is indicated by checking the Capacity box in the Applicable Products of the Pre-Qualification Application?
The Pre-Qualification Application is only applicable to the Phase 2 Capacity RFP for July 2011 through May 2012. The Phase 1 Capacity RFP for June 2011 was completed on April 13, 2011.
(Posted 4/19/11)
Will any fees be charged for the Phase 1 and Phase 2 Capacity RFPs?
Neither Bid Participation nor Supplier Fees will be charged for the Phase 1 (June 2011) Capacity RFP. Final details for the Phase 2 (July 2011 - May 2012) are not yet available, but it is expected that both a Bid Participation Fee and Supplier Fee will be in effect.
(Posted 4/12/11)
Please clarify the units for capacity bidding.
The units for the capacity procurements are Planning Resource Credits (PRCs). One PRC equals one MW-month. The $/PRC-month construct shown on the bid form is simply to emphasize that PRCs are monthly products.

Will there be a seperate bidder pre-qualification and registration form for the phase two July '11 - May '12 capacity auction? Or do you need to fill out the bidder pre-qualification and registration form for phase one to qualify for both phases of the capacity auction?
Bidder Pre-Qualification and Registration for Phase 2 of the Capacity RFP (July 2011 to May 2012) will be handled separately from the June 2011 RFP process. Forms for the Phase 2 process will be issued with the Phase 2 Capacity RFP. Bidders only need to complete the June 2011 Bidder Pre-Qualification and Registration Form if they plan to participate in June 2011 bidding on 4/13/11.
