Rocky Mountain Power & Rio Tinto Kennecott Agreement will reduce emissions along Wasatch Front

Utah Regulators Approve Deal to Shut Down 3 Coal Burning Units

South Jordan, Utah (Oct. 27, 2016) – The Utah Public Service Commission today approved a multi-year contract between Rio Tinto Kennecott and Rocky Mountain Power to provide savings and stability for the mining company and energy provider’s customers. As part of the agreement, Rio Tinto Kennecott will shut down three of its coal burning power units more than one year ahead of schedule after negotiating a contract to continue receiving electricity from Rocky Mountain Power.

“This is an important step in the state’s mission to continue improving air quality along the Wasatch Front,” said Colin Nexhip, Rio Tinto Kennecott interim managing director. “Shutting down our coal units will eliminate more than 3,500 tons of particulate and precursor emissions emitted annually from these facilities.”

“This agreement helps to provide rate stability for our customers and improves the air we breathe,” said Cindy A. Crane, Rocky Mountain Power president and CEO. “This agreement benefits our customers and helps keep Utah’s economy growing.”

The contract took years of negotiations and substantial support was provided by Governor Gary Herbert and Senator Stuart Adams to lay the groundwork for a beneficial agreement that met the needs of both companies while benefitting Utah.
