A single wind project, a 70 MW plant proposed by Zond Systems Inc, has been shortlisted by Texas utility Southwestern Public Service Co (SPS) in a renewables category announced on March 1. The utility, based in Amarillo, had issued a request for proposals for 300 MW of capacity in September. The tender shortlist contains 12 proposals totalling 604 MW, divided into the following resource categories: supply-side generation, off-system power purchases, demand-side management alternatives, and interruptible load. The utility's Bill Crenshaw says a final decision will be issued this summer. State regulators required SPS to make the solicitation to address alternatives to cogeneration and combustion turbine plants that it was looking at to meet its needs in 1998 and 1999. Sixteen proposals in all were submitted. Those short-listed must now issue final and best offers.
