Background

The initial plant was 28 MW and began operating in 1967. A second 50 MW unit of $300 million was built in 1997. The new unit - known as Healy Unit 2 or the Healy Clean Coal Project - was part of a U.S. Department of Energy program to advance experimental coal-burning technology, but was plagued by safety and reliability problems during two years of sporadic use (1998-99). Golden Valley Electric Association (GVEA) received permission from the Environmental Protection Agency in 2012 to restart the plant, and the utility acquired Healy Unit 2 the following year from the Alaska Industrial Development and Export Authority for about $44 million.[2] Healy Unit 2 began operating in May 2015, for the first time since 1999.[3]

Only two days after passing its commissioning test in March 2016, a “mill puff explosion” shut the plant down. As work crews began ramping the plant up to go online once more, a second mill puff explosion shut the plant down again in November 2016. The plant was determined to be in need of US$20 million in modifications. The plant is planned to be operational again in July 2018.[4] It returned to operation in September 2018.[5]

Opposition to Healy Plant

In March 2010 anti-coal groups targeted Golden Valley Electric Association's plan to restart an inactive Healy Power Plant but would have to go into debt as a result. The GVEA Ratepayers Alliance stated in response that the "black hole" for energy customers' money and opposed the plant's reopening.[6]
