BOUNTIFUL -- City officials have agreed to upgrade one of two small turbines at the city's power generating plant.

The city council voted unanimously this week to spend $77,554 to replace faulty injectors on the city's Taurus generator at the Bountiful City Light & Power facility along 200 West. The Taurus is the smallest of four generation units at the plant and has a five megawatt capacity compared to two new 13.5-megawatt units installed in 2012 and a 6.8 internal combustion unit also located at the plant.

Three faulty injectors were found during annual inspections of the power operating units conducted in February, according to Allen Johnson, director of BCPL. He said due to changes from the manufacturer, it is necessary to replace 12 injectors at the same time.

The new injectors require an additional piece of equipment, which will monitor the combustion and protect the generation unit from damaging vibration if the air/-fuel mix is not correct, according to Johnson.

The Taurus unit has more than 14,500 hours of operation and Johnson estimates it has another 15,000 to 25,000 hours of operation before it will need engine replacement.

He said the unit is part of the utility's plan to save money during peak periods of power use.

City officials spent almost $25 million to upgrade the power facility in 2012, which included replacing five old engines with the new natural-gas powered turbines, which are expected to cut emissions significantly at the plant.

Bountiful is one of 44 communities in Utah to own its own utility. All expenses over $10,000 incurred by the utility are subject to approval by the city council.
