A growing number of Tri-State member systems are taking advantage of Tri-State board policies that provide them with incentives to develop their own local renewable projects in their service territories. As of April 23 a total of 18 projects were in place or were pending board approval under policy 115.
The projects to date under this program range from a proposed geothermal project in New Mexico, at least six solar projects in New Mexico and Colorado, two landfill methane recovery ventures and a half-dozen existing and planned small hydro plants.
The largest member-supplied solar project slated to begin construction this fall on a 40-acre site near Norwood, Colo., is a 2-megawatt capacity PV plant that will be developed and operated by SunEdison Corp. Tri-State member, San Miguel Power Association (Nucla, Colo.) will purchase its output.
A new addition to the member renewable portfolio will be two landfill methane recovery projects that are planned by Poudre Valley REA (Ft. Collins, Colo.) and United Power (Brighton, Colo.). Poudre Valley’s 1.5-megawatt project is scheduled for completion by early 2011 and the larger United Power 4.5-megawatt Erie Landfill site is still in the preliminary planning stage.
Another renewable resource that has seen substantial development throughout the member service territory in the past few years is small hydro projects. Empire Electric (Empire, Colo.) is currently testing its new Cortez Hydro project, according to Susan Hunter, Tri-State’s long-term origination specialist. The 240-kilowatt unit is expected to begin commercial operation later this spring. San Luis Valley (Monte Vista, Colo.) will be bring on its 42-kilowatt Roaring Fork hydroplant this summer and San Miguel also has plans later this year for its third small hydroelectric plant, the 800-kilowatt Bridal Veil project.
To date, the largest distributed generation projects that are in operation are the 5.8- megawatt Williams Four Corners waste gas plant located in La Plata Electric’s (Durango, Colo.) service territory and the 4-megawatt Trailblazer waste heat recovery plant sited in Highline Electric’s (Holyoke, Colo.) service area. If all planned projects are completed as scheduled, Tri-State’s members will be producing a total of 25 megawatts of local renewable generation by next year.
