First Solar just announced that it will work with Tri-State Generation and Transmission Association to build a 30-MW solar power plant in Colfax County in northeastern New Mexico. The 5,000 solar modules will produce enough energy to power approximately 9,000 houses, and the plant is expected to be online by the end of next year. Tri-State Generation and Transmission Association has entered a 25-year purchase agreement for power to be produced at the plant, which will be called the Cimarron I Solar Project. The companies did not release any information about the financial terms of the deal.
