Arc flash mitigation bidding extended again at U.S. 25.5-MW Minidoka, 176.5-MW Palisades U.S. hydro projects

The bidding deadline has been extended again for arc flash mitigation at the 25.5-MW Minidoka and 176.564-MW Palisades hydroelectric projects in Idaho. Bids now are due Oct. 1.

The Bureau of Reclamation previously called for bids by Aug. 26, July 9, July 2 and June 25.

Reclamation awarded a contract in May to Alstom Power Inc. to overhaul two turbines at the Allen E. Inman power plant of the Minidoka complex. It celebrated completion of a new spillway at Minidoka on May 27. The agency awarded a contract to D.H. Ortega Construction LLC in 2012 to repair stilling basin concrete and replace an oil containment system at Palisades.

Reclamation now seeks bids for arc flash mitigation at the two projects. The work is valued at $1 million to $5 million.

Work at Minidoka includes replacement of low-voltage circuit breakers and fuses and replacement of medium-voltage fused disconnect switches with medium-voltage power circuit breakers. Work at Palisades requires replacement of low-voltage circuit breakers, medium-voltage switchgear with power circuit breakers, transformer overcurrent relays and associated current transformers.

Work at both sites includes installation of multi-function relays to provide differential and overcurrent protection to station service transformers and breaker failure protection to new power circuit breakers.
