TRI-STATE GENERATION AND TRANSMISSION ASSOCIATION, INC.

RENEWABLE ENERGY

Tri-State forecasts in 2016 that 25 percent of the energy delivered by the association and our member systems to consumers will come from renewable resources.

A strong advocate for the development of renewable energy projects of all sizes and technologies, Tri-State has added nearly 400 megawatts (MW) of renewable resources to its power portfolio since 2008. Another 200 MW of new utility scale and distributed generation projects are expected to be completed in 2016 and 2017.

WIND & SOLAR PROJECTS As wind and solar programs have become more cost-effective, Tri-State has partnered with developers to purchase the output from several large renewable projects located throughout its service territory. These projects include the following facilities:

COLORADO HIGHLANDS WIND91 MW, northeastern Colorado

KIT CARSON WINDPOWER51 MW, east-central Colorado

CIMARRON SOLAR30 MW, northeastern New Mexico

CAROUSEL WIND FARM150 MW, east-central Colorado,expected completion date of 2016

SAN ISABEL SOLAR30 MW, south-central Colorado,expected completion date of 2016

ALTA LUNA SOLAR25 MW, southern New Mexico,expected completion date of 2016

TWIN BUTTES II WIND76 MW, southeast Colorado,expected completion date of 2017

HYDROPOWER PROJECTS Clean, renewable hydropower has played a central role at Tri-State since the association’s founding. Tri-State today is one of the largest purchasers of federal hydropower in the West, and also buys the output from several small hydroelectric generation facilities located in and near our members’ service territories.

TRI-COUNTY WATER HYDROPOWER PROJECT8 MW, Ridgway, Colorado

VALLECITO HYDROELECTRIC PROJECT5.6 MW, near Durango, Colorado

BOULDER CANYON HYDROELECTRIC PROJECT 5 MW, Boulder, Colorado

WILLIAMS FORK HYDRO PLANT 3.6 MW, near Parshall, Colorado

GARLAND CANAL HYDROELECTRIC PROJECT 2.9 MW, near Powell, Wyoming

MANCOS HYDRO PROJECT ON JACKSON GULCH RESERVOIR 260 kW, Mancos, Colorado

MEMBER SYSTEM PROJECTS Tri-State works with its members to develop local, community-based renewable energy and distributed generation projects. In addition, our members have retail net metering programs for their member consumers. Tri-State helps to facilitate projects such as these in member systems’ service territories.

These renewable project policies support Tri-State members in developing local resources that diversify the power base while helping to meet renewable energy requirements in their home state. Sixteen of Tri-State’s members have developed or plan to develop over 82 MW of renewable and distributed generation projects as of April 30, 2016. A complete list of these projects can be found on the back page of this brochure.

TRI-STATE IS INCORPORATING RENEWABLE SOURCES OF ENERGY INTO ITS GENERATION PORTFOLIO TO BRING FURTHER VALUE TO THE MEMBER SYSTEMS ACROSS THE FOUR STATES IT SERVES.

VOLUNTARY RENEWABLE RESOURCE PROGRAM In addition to contracting for renewable resources to the benefit of the association’s own generating resource portfolio, Tri-State has provided the opportunity for consumers of its member systems to participate in the Voluntary Renewable Resource Program since 1998.

Through this program, Tri-State purchases Renewable Energy Credits (RECs) for member systems’ retail consumers who participate in the voluntary subscription program. The RECs that Tri-State obtains for the program are generated from wind, solar, geothermal, small hydroelectric and biomass resources.

RESOURCE PLANNING Tri-State considers renewable energy projects and programs in the context of a larger Integrated Resource Planning (IRP) process by which the association evaluates new generation and demand-side alternatives to ensure it can continue serving its members with affordable and reliable power.

Tri-State updates this process annually and undertakes a complete analysis (both open to the public) every four years.
