The Omaha Public Power District (OPPD) board has voted to authorize repairs, estimated at $1.7m, to Unit 4B at the gas-fired Sarpy County power station in Bellevue, Nebraska.
The Sarpy County power plant is fueled by natural gas and the unit in question was commissioned in 2000 and has a nameplate capacity of 59 MW, according to GenerationHub data.
OPPD staff wants to have repairs made to the 4B engine prior to the 2017 peak power season to avoid lost revenues. Internal damage was discovered at the facility during a mid-September inspection.
Only the original equipment manufacturer, PW Power Systems, is known to have the tooling, parts and expertise to perform the necessary repairs, according to a staff memo to the OPPD board.
“Deterioration and liberation of J-Seal segments is leading to internal damage in the 4B engine,” according background material. Unit 4 can only run at half capacity until the engine in question is repaired.
