Alstom wins LADWP hydro rehabilitation contract

Alstom has been awarded a hydro rehabilitation contract worth approximately $30 million by the Los Angeles Department of Water and Power (LADWP).

Under the terms of the contract, Alstom will design, install and commission a new Alstom-patented Hooped Pelton runner, which is an impulse turbine with buckets supported by two separate hoops, a new generator and new governor, as well as provide an exciter and controls for unit 7 of the Castaic hydropower plant. The 1,250 MW hydropower plant is in Castaic, Calif, approximately 35 miles north of Los Angeles. Commissioning is expected in 2014.

Six of the seven units in the plant are pumped-storage units, while unit 7 is a conventional 55 MW Pelton unit. Alstom has already supplied LADWP with heat recovery steam generators, steam turbines and conventional steam boilers, and continues to provide the utility with aftermarket steam turbine, generator and boiler service in the form of parts supply and field service assistance.
