List of Power Plants

View Cogeneration Project Slideshow

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.

View Glennallen Diesel Plant Slideshow

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.


View Valdez Diesel Plant Slideshow

The Valdez Diesel Plant (VDP) was constructed after the 1964 Good Friday Earthquake that caused the City of Valdez to relocate to its present location. The available capacity of the plant is 9-megawatts. The plant houses; three Enterprise DSR46 units and two Caterpillar 3516B units. The two Caterpillar units were installed in 2016 and commissioned in 2017. These two units replaced a total of four aging, failing, inefficient 1960 and 1970 vintage units in order to provide more efficient, cost effective, reliable power to CVEA consumers.



View Solomon Gulch Hydroelectric Facility Slideshow

Solomon Gulch power plant began providing power to CVEA customers in 1982. The 12-megawatt Solomon Gulch hydroelectric facility is located on Dayville Road in Valdez. Solomon Lake is impounded by a 115 foot tall by 386 foot long earth fill concrete and asphalt faced dam. The water is routed to the power house through two 48-inch, 3,800 foot long, steel penstocks. Power is generated by two Fuji Francis style turbines. The first complete unit overhauls were performed in 2010 and 2012 after nearly 30 years and over 100,000 hours of operation on the units. Solomon Gulch produces a majority of CVEA's energy needs.


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.

View Allison Creek Hydroelectric Facility Slideshow

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.

For detailed information on the Allison Creek Hydroelectric Project, visit the Allison creek website.

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.

Dedication of Dan Smith SubstationOn 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.
