Allison Creek Hydroelectric Project
Construction Update-October 2015
The Allison Creek Hydroelectric Project will soon finish its second construction season and the project remains on track for a 2016 start. This year's construction focused around the diversion structure, the penstock and the inside work at the power house. This year, the diversion structure took shape and received over 1000 cubic yards of concrete. We completed the installation of all penstock pieces, except about 20 that will be installed in 2016. Remember each piece of pipe is approximately 40 feet in length and will ultimately be made up of 171 pieces and will be 1 and 1/4 miles long. The power house started this season as an empty building. It now houses a bridge crane, main shutoff valve, the bifurcation valve, the turbine housing, the pelton wheel, the generator stator and rotar, and other equipment. In addition, the dispatch office and restroom have been built and the heating and ventilation ducting have been installed. It has also been wired for lighting, production of power, communications, controls, cameras, transformers, and much more.

Milestones for the 2015 season will include completion of the penstock, construction of the diversion structure, and installation of the powerhouse equipment. CVEA is still on target to begin producing commercial hydropower from the project in 2016 when the creek allows a full commissioning of the power plant.
Construction Update-November 2014
The first construction season of the Allison Creek Hydroelectric Project ended mid-November. Every goal of the project was met or exceeded during the first construction season including ground clearing and building of the lower and upper access roads, blasting and building of the tunnel, building of the powerhouse structure, laying the first stretch of the penstock, and installation of the feeder line.
The high cost of fuel continues to plague CVEA members. We cannot control the cost of fuel. We can, however, work to lessen our reliance on fuel for power generation, and it is with this goal in mind that CVEA continues to work toward its vision to reduce or eliminate our dependence on fossil fuel and to stabilize the Cooperative's cost of generation with regional, sustainable resources.
CVEA believes hydropower is the most viable and cost-effective renewable resource and has continued to aggressively move the Allison Creek Hydroelectric Project forward since efforts began in 2008.
Allison Creek promises several renewable energy benefits:
It will displace 725,000 gallons of fuel annually when it is commissioned in 2016
It will eliminate 12,000 tons of carbon dioxide annually
It will reduce annual fuel costs by $2.415 million every year
It will generate 15 million kWhs to increase CVEA's renewable energy portfolio from 50 to 64 percent of total generation requirements
It will save members over $800,000 in the first year
