Frequently Asked Questions
Roundhouse Renewable Energy is a proposed 150-megawatt (MW) wind energy facility. The wind turbines will be located on 30,000 acres of private and state land southwest of Cheyenne in Laramie County, Wyoming. A new transmission line, which is needed to deliver additional renewable energy to Platte River Power Authority’s owner communities (Estes Park, Fort Collins, Longmont and Loveland), will be located in Larimer County and potentially Weld County, Colorado.
The facility is expected to begin commercial operations at the end of 2020. Enyo Renewable Energy, the developer of the Roundhouse Project, is an independent solar and wind energy company that specializes in developing utility-scale renewable energy projects in Wyoming and across the Intermountain West. Roundhouse Renewable Energy is currently working with local, state and federal regulatory agencies in Colorado and Wyoming to obtain the necessary approvals to permit and construct the facility. The principals of Enyo developed the Pioneer Wind Project in Converse County, Wyoming, the first wind project built in the State of Wyoming since 2011.
Platte River has committed to purchasing power from Roundhouse Renewable Energy through a power purchase agreement (PPA). Platte River is a not-for-profit utility that generates and delivers safe, reliable, environmentally responsible, and competitively priced energy and services to its owner communities. Platte River will use the power generated by Roundhouse Renewable Energy to meet the needs of customers within its service area.
As currently planned, Roundhouse Renewable Energy will have 150 MW of capacity. In 2017, wind power comprised about 11 percent of the electricity Platte River sent to its four owner-municipalities. Roundhouse would nearly triple Platte River’s wind capacity.
Roundhouse Renewable Energy will use approximately 75 turbines. The size and manufacturer will be determined later in 2018.
By the end of 2018, Platte River has the option to add up to 75 MW of additional wind capacity.
The turbines will be connected to each other and to an on-site substation via underground collector lines. From the project substation in Wyoming, an above-ground 230-kilovolt (kV) transmission line would carry the project’s power output approximately 19 miles south to Platte River’s Rawhide Energy Station in Larimer County, Colorado. Approximately 7 miles of the transmission line would be located in Wyoming, and approximately 12 miles is proposed to be located in Colorado, mostly on the City of Fort Collins’ Meadow Springs Ranch.
The transmission line would consist of either wood H-frame or steel monopoles (galvanized or rust colored Corten) as determined through the planning process. Structures would range in height from 80 feet to 100 feet, depending on the length of span. The typical span length between transmission structures is 700 feet, with longer spans of 1,200 feet to avoid sensitive environmental resources. Renderings of the proposed line will be made available later in 2018.
The Roundhouse area currently consists of ranching land leased primarily from Duck Creek Grazing Association (DCGA). DCGA is an association of families who share in the ownership of the ranch and jointly manage their permitted livestock and the range resources. The proposed transmission line would be largely sited on City of Fort Collins’ Meadow Springs Ranch in Colorado.
The Roundhouse leases allow landowners to maintain control of their land and continue to raise cattle within the project area. Following construction, the footprint for each turbine and transmission line structure will be small. Areas disturbed during construction will be re-seeded with native vegetation and pasture grasses at the request of the landowners. Thus, the properties will continue to be used for ranching during operation of the Roundhouse Renewable Energy Project.
Over the course of a year, the project will generate an amount of electricity equivalent to the annual energy needs of approximately 70,500 homes. This carbon free electricity could fuel:
- 100% of all of the homes in Fort Collins (65,518) plus Estes Park (3,140) based on the 2015 American Community Survey; OR
- 100% of all of the homes in Loveland (30,269) and Longmont (35,538); OR
Enough carbon free electricity for half of all of the homes in these four cities.
Cheyenne and Laramie County, Wyoming: Roundhouse will generate millions of dollars in tax revenue for Laramie County to support local services like schools, roads, police, fire protection, and other essential government services. The project will pay the Wyoming wind generation tax, which will be split between Laramie County and the State of Wyoming. Landowners within the project area will benefit from the revenue generated by wind turbines on their land. It is currently anticipated that the Project will bring 250 jobs during construction and 10 permanent, full-time operations and maintenance jobs after completion. Local labor and materials will be used where possible.
Estes Park, Fort Collins, Longmont and Loveland, Colorado: Completion of the Roundhouse Renewable Energy project will become a significant step toward achieving renewable energy goals for all Platte River owner communities, including the Fort Collins Climate Action Plan and Longmont’s renewable energy standard. Local governments will further benefit from payments for the transmission line easement and from property taxes.
Enyo Renewable Energy is currently studying wildlife use in the wind farm and transmission line route to evaluate potential impacts to wildlife associated with construction and operation of the project. Although we do not yet have site-specific migration data for Roundhouse, the site is not thought to be located in a major raptor or big game migration corridor. Raptor migration is more likely to be concentrated along the higher elevation ridgelines over 10 miles west of the project.
Based on bird surveys completed to date, there appears to be limited use of the project site by eagles. The most commonly observed raptors at the site include the red-tailed hawk, rough-legged hawk, northern harrier, and American kestrel. Common songbirds observed on the site include horned larks and western meadowlarks.
Site-specific impact analyses for birds and other wildlife have not yet been conducted but the following link provides general information on the impacts of wind energy facilities on wildlife. This and additional information on the effects of wind energy on wildlife can be found at: https://awwi.org/wp-content/uploads/2017/07/AWWI-Wind-Wildlife-Interactions-Summary-June-2017.pdf
The project is being developed with landowners and Federal and state agencies to minimize impacts to natural resources, including wildlife. For example, the project’s transmission line will be designed according to Avian Power Line Interaction Committee (APLIC) standards, thereby avoiding or minimizing the potential for avian electrocutions. Roundhouse is preparing a Bird and Bat Conservation Strategy in consultation with Federal and state agencies to identify effective measures, such as curtailing (stopping) blade rotation at low wind speeds which has been found to substantially reduce bat fatalities at other wind farms.
Roundhouse will be working with landowners, Platte River, Larimer County and City of Fort Collins Utility and Natural Areas staff, and their respective citizen boards throughout this process.
- Elected officials and Planning Commission at Larimer County will review the project and hold public hearings following submittal of the 1041 permit application. A siting study to establish the transmission line route commenced in March 2018 and the proposed transmission line route is expected to be determined in July 2018. Biological, visual and cultural resource surveys and other supporting environmental analysis will be completed the Summer of 2018
- If the transmission line crosses into Weld County, a second land use permit will be required as well, following a similar process of public hearings.
- A transmission line easement will be purchased from willing landowners.
