First round bids for Sempra Generation and Carlyle/Riverstone Holdings' 632 MW coal-fired Coleto Creek Power Station have been pushed to Friday. Bids were expected to be submitted Feb. 10 but the sellers have opted to give prospective investors more time, say watchers.

Calls to Art Larson, spokesman at Sempra in San Diego and Michael Hoffman, managing director at Carlyle/Riverstone in New York were not returned. A call to Pete Labbat, managing director at Goldman Sachs in New York, which is running the sales process, also did not return a call for comment.

Sempra is auctioning the plant, which is held in the Topaz Power Group joint venture along with Riverstone, late last year (PFR, 12/19). The remaining plants in Topaz are also up for sale but details on that process, being handled by boutique firm Greenhill & Co., could not be learned.
