Document Description
YCWA owns and operates Narrows 2 Powerhouse (powerhouse) located 400 feet downstream of Englebright Dam. The powerhouse receives the water to drive its turbine from Englebright Reservoir. The powerhouse has one 55,000 kVA Toshiba Generator with an existing oil filled generator step up transformer (GSU transformer). YCWA is purchasing a replacement GSU transformer for the powerhouse since the existing GSU transformer is 1969 vintage design. The Proposed Project will construct a permanent location to house the existing (back-up) GSU transformer. Once the new transformer is installed at the powerhouse the back-up GSU transformer would be placed on the newly constructed concrete pad located ~1/2 mile from the powerhouse. The back-up GSU transformer would be used if the primary transformer needs replacement or repairs that necessitates it being taken to an off-site location. Construction would also include installation of two new power poles and electrical infrastructure needed to periodically test fans and pumps on the back-up GSU transformer.
