A bold vision took shape in the late 1970s, one that would power communities for generations
and reflect the foresight of Platte River Power Authority and its partners. On Sept. 27, 1979, the
Yampa Project’s first generating unit was dedicated at Craig Station, marking the beginning of a
new era in regional energy production. With over 1,000 guests in attendance, the dedication
ceremony featured bronze plaques from the four project owners, guided tours of the facility and
a western-style barbecue—a fitting celebration for Colorado’s newest and largest electric
generating station.
Platte River’s 18% ownership in Craig Units 1 and 2 provided a significant boost to its
generating capacity. By 1981, both units were operating commercially, increasing Platte River’s
resources from 100 MW to 254 MW including our hydro allocations and delivering nearly
990,000 MWh annually. Despite minor outages, the units achieved a combined load factor of
99.3% in March 1981, demonstrating their reliability and importance to Platte River’s system.
But the story of Craig Station is not just about generation, it’s also about innovation in fuel
supply. Originally, coal was sourced from the adjacent Trapper Mine, owned by Utah
International. In 1984, the Yampa participants made a strategic decision to acquire the mine
through a jointly owned corporation. This move provided a stable, cost-effective fuel supply and
eliminated the need for repeated price negotiations. By 1987, Trapper Mine was expected to
meet 100% of Craig Station’s coal requirements, with recoverable reserves of approximately
264 million tons, enough to support the station’s full economic life.
Trapper Mine’s ownership structure, with Platte River holding a 27.14% share, allowed for direct
management of production levels and costs. This mitigated fuel price volatility and contributed to
Craig Station becoming Platte River’s second-lowest operating cost resource. The mine’s
proximity to the station further enhanced efficiency and reliability.
Over the decades, Craig Station has undergone environmental upgrades to reduce sulfur and
particulate emissions, maintaining compliance with evolving regulations. Yet, as the energy
landscape shifts, so too must legacy resources. Craig Unit 1 will be retired at the end of 2025,
followed by Unit 2 in 2028. Until then, Trapper Mine will continue supplying coal to Unit 2. After
its closure, the mine will begin its reclamation phase. These steps reflect Platte River’s ongoing
commitment to a noncarbon future.
The legacy of Craig Station and Trapper Mine is one of strategic planning, technological
advancement and collaborative ownership. These resources powered our communities through
decades of growth and change. As we transition to cleaner energy sources, we honor the
innovation and foresight that built the foundation we stand on today.
