“This acquisition contributes to an evolving resource portfolio that will continue to provide reliable, affordable and sustainable energy for our customers for many years to come,” said David G. Hutchens, TEP’s President and Chief Executive Officer.
Gila River Power Block 3, completed in 2003, features combined cycle technology that improves fuel efficiency by capturing waste heat and using it to help generate additional electricity.
TEP is planning to significantly reduce its coal-fired generation capacity in coming years:
- At the end of this year, the expiration of a lease for a unit at the Springerville Generating Station in eastern Arizona will remove approximately 200 MW of coal-fired capacity from the companyÂ’s portfolio.
- By the end of 2017, TEP will begin using natural gas exclusively as a fuel source for Unit 4 at the H. Wilson Sundt Generating Station in Tucson, removing another 120 MW of coal-fired capacity.
- The company also is planning for the 2017 shutdown of Unit 2 at the San Juan Generating Station in New Mexico TEP owns 170 MW of that coal-fired unit.
This portfolio diversification strategy will reduce TEP’s overall coal capacity by approximately 490 MW, or about 32 percent, by 2018. “Our resource plan will result in a 25 percent reduction in carbon dioxide emissions by 2020 without compromising the affordability, safety, or reliability of our service,” Hutchens said.
Acquiring Gila River Power Block 3 is one of several steps TEP is taking to replace that coal power and diversify its generation portfolio. The company continues to be a leader in its industry by expanding its renewable resource portfolio, with a 35-MW solar array near Green Valley and a nearly 18-MW system at Fort Huachuca in Sierra Vista scheduled to come online this month.
By the end of 2014, TEP expects to have more than 340 MW of total renewable generating capacity, enough to meet the electric needs of more than 71,000 homes. TEPÂ’s successful track record of solar energy development has earned the company repeated recognition among the Solar Electric Power AssociationÂ’s Top 10 Utility Solar Rankings as well as the honor of being named the groupÂ’s 2012 Investor-Owned Utility of the Year.
In addition to the continued expansion of its renewable solar and wind resources, TEP will be relying on cost-effective energy efficiency programs and will evaluate new storage technologies to help manage the intermittent output of renewable resources.
