UPDATE – U.S. extends generator repair date at 558-MW Bonneville Second

The Corps of Engineers has extended the deadline for bids to repair a generator in the 558-MW Second Powerhouse of 1,076.6-MW Bonneville Dam, on the Columbia River in Oregon.

The Corps said the response date was extended to July 30, 2009, “solely for the purpose of keeping the announcement active.” It said another solicitation would be issued soon with a response date of 30 days after issuance.

The agency previously said bids were due July 8, extending a tentative due date of May 8 in a previous notice. (HydroWorld 5/26/09)

Work is to involve Unit 11, a 70-megavolt-ampere, 18.8-kilovolt, 69.23-rpm generator with a rotor diameter of about 37 feet and a rotor height of 56 inches. The unit is one of 20 generators at the Bonneville Dam hydroelectric project.

The contractor is to move the generator stator so that it is round, plumb, and properly aligned to the turbine shaft; test and repair stator laminations; shrink the rotor rim onto rotor spider arms; and inspect and repair the unit’s upper guide bearing and associated vapor ring.

The Corps says it intends to award a firm fixed-price contract. It estimates the value of the work will range from $500,000 to $1 million.
