Check out this 5-minute video about the 伊娃溪风 Farm explaining what went into constructing the 伊娃溪风 Farm.
The first power from 伊娃溪风 came into the grid at 9 a.m. 2012年10月24日. On January 7, 2013, all 12 turbines were fully tested, commissioned and generating power.
At just under 25 megawatts, Eva Creek is the largest wind project in Alaska and the first by any Railbelt utility. It is located 14 miles from Healy at the top of the 10-mile Ferry mining road.
The 伊娃溪风 project is visible from the Parks Highway. As you’re headed north out of Healy, look to the right in the vicinity of Milepost 263.
The addition of 伊娃溪风 is exciting for Golden Valley Electric Association (GVEA) and the Interior as a whole. The project integrates well into GVEA’s system and enables the cooperative to meet its 可再生能源 Pledge ahead of schedule. 伊娃溪风 also helps reduce the Interior’s dependence on oil for power generation.
快速的事实
- 容量:24.6兆瓦

项目时间表
2009年以前
- Installed first meteorological wind monitoring towers (2003)
- Began wind-integration studies to make sure the wind power will work on GVEA’s system (2007)
2009
- Installed 2 80-meter MET towers at Eva Creek site and 1 50-meter MET tower on Walker Dome for further wind testing
2010
- Wetland survey and avian migration studies conducted for permitting process
- Geotechnical investigation done for road and site improvements
- Met with Alaska Railroad Corporation regarding rail access issues
2011
- Began infrastructure design (road, intertie, tower foundation and communications)
- Contracts awarded; Michels Wind 能源 is the general contractor
- Conducted cultural resources surveys and wetlands field surveys
- Road improvements began
- Acquired permit from U.S. Army Corps of Engineers, 阿拉斯加州, Division of Natural Resources; began public and agency review process for land lease, 材料网站, 销售合同, communication sites, 道路改善, 和调整, 等.
- Selected REpower as turbine manufacturer
2012
- 阿拉斯加州, Division of Natural Resources, executed Early Entry Authorization for the construction, 操作,
- maintenance and use of the wind farm
- Construction and turbine erection
- First wind power hit the grid (October 24)
- Commissioning and testing
- All 12 turbines commissioned (December 31)
2013 to 2014
- Full commercial output (January 7, 2013)
- Post-construction avian mortality studies to be conducted for the spring and fall migrations as a part of GVEA’s United
- 州鱼 & Wildlife Avian Protection Plan (2013 and 2014)
2016
- In August and September, all 12 turbines were fitted with sensing devices
- This was so that if any bearings fail, they will be detected instantly and the turbines will automatically shut down, pending visual inspection
2017 to 2019
- Continued full commercial output with no issues
2020
- 在2月份, Senvion (the original equipment manufacturer) declared bankruptcy and was purchased by Siemens Gamesa of Germany
- They faulted on their contract to perform the 操作s and maintenance on the facility
- GVEA took over the 操作s and maintenance of 伊娃溪风 Farm in March 2020
- Reliable wind energy continues to be provided
