Cimarron Solar Facility


Tri-State worked with First Solar and Southern Company to develop a 30 megawatt (MW) solar farm in northeastern New Mexico, within the service territory of Tri-State member system Springer Electric Cooperative.  The Cimarron Solar Facility is the largest solar PV project by an electric cooperative and one of the largest facilities of its kind.

First Solar is a leading manufacturer of thin-film PV solar modules and developed the industry's first pre-funded module collection and recycling program.  It is the first company in the world to bring the PV panel manufacturing cost below $1 per watt.


Locally sourced materials were used to the greatest extent possible at Cimarron.  There is no use of water during normal operation and the plant is virtually silent.
