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]
Retirement Plans
In June 2022, Golden Valley announced intentions to retire the plant by the end of 2024. The company planned to pursue the development of a large wind farm in its place. In addition, they would retrofit the smaller, 28 MW Unit 1 with pollution control equipment.[6]
In February 2024, Golden Valley Electric Association’s board of directors approved changes to the utility’s 2022 Strategic Generation Plan. Instead of retiring Unit 2 in 2024 as previously planned, Golden Valley would “[c]ontinue operating Healy Unit 2 until such time as alternative sources of reliable, lower cost energy are available.”[7]
Construction Financing for Healy 2
The construction of Healy 2 was financed by the Department Of Energy ($120 million), Alaska Legislature ($25 million), Alaska Industrial Development and Export Authority (AIDEA) ($150 million), and Golden Valley Electric Association (GVEA) & Usibelli Coal Mine ($10 million plus in-kind contributions).[8]
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.[9]
