UTILITY BOARD APPROVES OVERHAUL & CORRECTIVE MAINTENANCE OF GENERATION UNITS

10/25/2007 ~ The Utility Board recently approved the overhaul and corrective maintenance of two generation units at there regular meeting on Wednesday, October 24th.

Combustion Turbine* (CT) Two is scheduled to go offline in early December through February 2008 to undergo a major overhaul that is required every 10 years. The overhaul will enhance operational efficiency of the unit.

CT One is also scheduled to go offline briefly during the same timeframe to undergo corrective maintenance.

GE Energy Services was awarded the $1,368,411 bid for the overhaul of CT Two and the installation of a torque converter on CT One. KEYS will also perform additional corrective maintenance on CT One when the unit is down for repairs.

CT One and Two account for 18 and 14 megawatts** (MW), respectively, of the 111.5 MW of local generation available to KEYS. As a result of the overhaul of CT Two, four additional MW are expected to be available when the project is complete, bringing local generation to 115.5 MW.

Local generation is the result of the Utility Board’s 60-percent on-island, back-up generation policy to ensure power reliability. Because KEYS is dependant on a transmission line (TIELINE) to input power from the mainland, the Board feels it is necessary to have local generation capabilities. Should the TIELINE become compromised, KEYS can utilize local generation that will supply up to 60-percent of the service areas peak power requirements. If KEYS customers exercise conservation measures, local generation can supply the power demand.

The regular meeting of the Utility Board took place at 5:00 p.m., Wednesday, October 24th, in the Louis Carbonell Board Room of the William Arnold Service Building, 1001 James Street, Key West.

*Combustion Turbine – Works much like a jet engine; outside air is compressed into a combustion chamber where fuel is burned. The hot gases from the burning fuel-air mixture drive the turbine, which in turn rotates a generator that produces electricity.

**Megawatt (MW) – A unit of electric real power equal to 1,000 kilowatts or 1,000,000 watts.
