List of Power Plants
The Cogeneration Plant (Cogen)is a state-of-the-art facility located at the Petro Star Valdez Refinery on Dayville Road. The plant was commissioned in the spring of 2000 as a joint effort between CVEA and Petro Star. It is a 5.2-megawatt Solar Taurus 60 turbine that utilizes Light Straight Run (LSR), a less refined naptha type fuel, as the fuel source supplied by the refinery. The exhaust heat from the turbine is diverted to a crude heater through a six foot diameter insulated pipe, for Petro Star use in the refining process. The Cogen is the primary plant utilized during the winter months. The Cogen provides additional benefit to CVEA members as 90 percent of the heat sales back to Petro Star are credited directly to members as a heat credit on the power bill.
The Glennallen Diesel Plant (GDP) is the oldest of CVEA's power plants. The original portion of the plant was constructed in the mid 1950's and expanded in the 1970's to meet our customers' needs. The available generation capacity of the plant is 11-megawatts. The GDP houses a total of seven diesel engines; three Fairbanks Morse 38D8 1/8 opposed piston units, two Enterprise DSR46 units, one Caterpillar 3516B, and one EMD 16-710, which is our newest unit installed in 2009.
Directly across Dayville Road from the Solomon Gulch Plant is the Valdez Fisheries Development Association's (VFDA) Valdez Hatchery. Fresh water is supplied from the Solomon Gulch power plant for the fish raring process at the hatchery through various piping routed between the two facilities.
CVEA operates its dispatch center from this facility. The plant is manned 24 hours a day, seven days a week. Plant operators are responsible for the monitoring and control of up to five generation plants, all six substations, and transmission and distribution assets at one time via remote control operations (SCADA). The SCADA system at Solomon Gulch was updated over a four year period of time and commissioned in 2017.
Allison Creek is the newest of CVEA's generation plants. After many years of studies, and permitting, construction began in May 2014 and the project was commissioned on October 5, 2016. The plant is located at the end of Dayville road next to the Alyeska Alaska Marine Terminal. Allison Creek is a run of the river project which backs up a small amount of water in the creek with a diversion structure, at elevation 1,310 feet above sea level, and routes the water through a 42-inch, 7,000-foot long penstock to the power house. Power is then generated with a 6.5-megawatt, Canyon Hydro Pelton style turbine.
Allison Creek and Solomon Gulch combined are estimated to produce nearly 70-percent of CVEA's energy requirements.
CVEA's service areas are tied together with a 106-mile, 138-kilovolt transmission line that is owned and operated by CVEA. The transmission line provides the link to all five generating plants. Power can flow from any of the generating plants to the end consumers. Historically, power flows from Valdez to the Copper Basin in the summer months, as nearly all of the power requirements are met with our two hydroelectric plants. The transmission line traverses severe terrain between the two districts and parts of it, in the Thompson Pass area, which is known for being one of the snowiest places in North America. In 2014 nearly four-miles of the transmission line through Thompson Pass was relocated to minimize the risk of avalanche danger and to mitigate the risk to CVEA's Linemen that would have to work on getting the line back together if it were struck by an avalanche, as it was on many occasions in the past.
On May 11, 1996, the substation connected to the VDP was dedicated to Don Raymond Smith, a 20-year CVEA Lineman who passed away. The substation was renamed to the Don Smith Substation, a sign, plaque, and Don's climbing hooks and hardhat were bronzed and mounted to the plaque in memory of Don.
On September 16, 2013, the hiking trail to the Solomon Gulch Dam was dedicated to John Hunter, a 38-year dedicated employee with CVEA who passed away. The hiking trail was renamed to the John Hunter Memorial Trail, with a plaque at the trailhead. John started with CVEA as an Operator at the Valdez Diesel Plant, then became the first Chief Plant Operator at Solomon Gulch, and retired as the Production Manger in May 2012.
