May 10, 2013 PTC Wind Bid Reduced Pricing Request

On May 10, 2013 Public Service Company notified the Commission that it is allowing PTC Wind Bidders that submitted bids on April 30, 2013 the opportunity to offer the Company reduced PTC Wind Bid pricing.  This opportunity to provide reduce pricing and the process for doing so were developed in consultation with the Independent Evaluator (“IE”).

All PTC Wind Bidders have been notified via email concerning the procedures to be followed to submit their reduced bid prices.  Reduced PTC Wind Bid prices are due no later than 4:00 PM MDT on May 17, 2013.   The PTC Wind Bidders have been directed to send their reduced PTC Wind Bid via email to the IE.   This re-pricing process will not delay the schedule for completing the evaluation of PTC Wind Bids and filing the results of that evaluation with the Commission on May 30, 2013.

PTC Wind Bids

Because of the significant impact of the Production Tax Credit (PTC) on the cost of wind energy and the opportunity created by the extension of the PTC, Public Service is considering PTC Wind Bids on an expedited schedule from the other bids in this All Source Solicitation. Bidders who intend to submit a bid for a PTC wind resource should take note of the expedited schedule for PTC wind bids as enumerated in the 2013 Renewable Resources RFP and in the Bid Schedule below.  Additional information regarding PTC Wind Bids can be found in Section 6.0 of the 2013 Renewable Resources RFP.

Submittal of Bids:  Respondents that intend to submit a bid are encouraged to submit a non-binding Form A: Notice of Intent to Respond (NOIR).  Submit the completed NOIR by email no later than 4:00 P.M.
