Output at Colorado Highlands Wind increased by 36 percent

The expansion of Colorado's newest renewable energy facility is complete, with the Colorado Highlands Wind project now capable of generating 91 megawatts of electricity for Tri-State Generation and Transmission Association.

The facility originally came on-line in December of 2012, with 42 1.6-megawatt GE turbines able to produce 67 megawatts of power. The expansion – which was announced in April and began construction in July – consists of an additional 14 1.7-megawatt GE turbines, increasing the facility's total current capacity by 36 percent.

Tri-State has a 20-year power purchase agreement to receive all the electricity and environmental attributes from the wind farm, which is jointly owned by Alliance Power, Inc. of Littleton, Colo., and GE Energy Financial Services of Stamford, Conn. It is located on 6,640 acres in northeast Colorado's Logan County – in the service territory of Tri-State member co-op Highline Electric Association.

"Colorado Highlands Wind has been performing extremely well since being brought on-line late last year," said Tri-State senior vice president Brad Nebergall. "Since it was originally designed to accommodate 91 megawatts on the existing transmission system – and since Tri-State is always proactively pursuing projects that make sense for us and our member electric co-ops – the expansion of Colorado Highlands Wind was an opportunity we quickly embraced."

Jim Michael, managing member of Colorado Highlands Wind, said, "We are pleased to be able to increase the long-term cost-effective renewable energy that our project is generating for Tri-State and its members, while providing other significant benefits to the community."

Colorado Highlands Wind is currently one of three utility-scale renewable energy facilities from which Tri-State receives all of the electrical output and renewable energy credits.

In 2010 the wholesale power supplier began purchasing the electricity generated at the 51-megawatt Kit Carson Windpower Project in eastern Colorado as well as the 30-megawatt Cimarron Solar Facility in northeastern New Mexico. Combined with Tri-State's renewable hydropower resources, renewable energy generation makes up approximately 18 percent of the energy the association provides to its member co-ops.

In addition, Tri-State's member co-ops have another 49 megawatts of local, community-based renewable and distributed generation projects in operation or scheduled to be operational in the near future.

In 2013, Tri-State adopted a new wholesale rate, along with demand management and energy shaping product offerings that, among other benefits, will assist the association to better integrate intermittent renewable resources into its power supply.

Based in the Denver suburb of Westminster, Tri-State Generation and Transmission Association is a not-for-profit wholesale power supplier to 44 electric cooperatives and public power districts serving approximately 1.5 million consumers throughout a 200,000 square-mile service territory across Colorado, Nebraska, New Mexico and Wyoming.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
