In early April, Holy Cross Energy (HCE) announced that it was partnering with Colorado Mountain College (CMC) to develop a large photovoltaic solar array near Glenwood Springs. The installation, which will be built on CMC-owned land near its Spring Valley campus, will have a generating capacity of 4.5 megawatts (MW). It will also include a battery storage component of 5 MW, or 15 megawatt-hours (MWh). Construction, operation and maintenance of the facility will be undertaken by Massachusetts-based Ameresco, Inc., a leading developer of renewable-energy resources. Under a Power Purchase Agreement with HCE, Ameresco will then provide renewable power to the utility.
