Community Solar: Case Studies

Solar Energy Development Informational Report to the Kankakee County Board   

       D. Skimerhorn and E. Blair (2017)

 “Since the [Future Energy Jobs] Act was passed, Kankakee County’s planning staff has seen a flurry of activity from solar developers looking for sites in the county. As a result of this activity, planning staff developed a solar farm ordinance which was adopted by the County Board in May of 2017 as an amendment to its Zoning Ordinance. On a side note, this ordinance was one of the first to be developed in the State of Illinois and is being used as a model ordinance by many counties and municipalities.”

Insights from the Colorado Energy Office Low-Income Community Solar Demonstration Project

Colorado Energy Office, Dec. 2017

This report describes and evaluates eight Colorado Low-Income Community Solar Demonstration Projects.

"[The Colorado Energy Office (CEO)] recognized the potential for community solar to reduce low-income energy burden and initiated the Low-Income Community Solar Demonstration Project (Demonstration Project). CEO awarded GRID Alternatives -- a non-profit focused on providing solar power to low-income families -- a $1.2 million grant to implement the development of eight demonstration models throughout Colorado with non-regulated utilities. The Demonstration Project was designed to help reduce energy burden for over 300 low-income households and better understand how utility and project structures affect the ability to make low-income community solar beneficial for both utilities and low-income subscribers. CEO’s Demonstration Project shows the feasibility of building a low-income community solar model that can be repeated throughout the United States, reducing the energy burden for all low-income households....

"Each project was designed differently to help identify optimal utility project structures and to identify opportunities for implementation in investor-owned utility territories. While each project provided a distinct set of lessons learned and policy recommendations, one item remained consistent -- each subscriber greatly benefited from the program and saved 15 to 50 percent on his or her electricity bills. These savings equated to, on average, $382 per subscriber. It is expected that the project will reduce electricity costs for the 380 subscribers by over $145,160 in the first year and more than $3 million over the lifetime of the project."

Selling Out 1.55 MW of Community Solar in 7 Weeks: Inside the City of Fremont, Nebraska's Community Solar Program

Smart Electric Power Alliance, Dec. 2017

"Overwhelmingly, the more than 500 people who attended the meetings wanted 'community' to be central to the project. They wanted the electricity from the project to be sold only to those in the Fremont community. They also wanted it built by local developers, financed by local money and under community control. Additionally, some folks were looking to take advantage of the 30-percent federal investment tax credit for solar, while others were looking to fix their energy costs without a big upfront investment."

 

Financing Community-Based Solar Projects: Case Studies from the Field” (May 2018)

 Six case studies, with focus on strategies for funding community solar projects

National Rural Electric Cooperative Association

144 electric utility cooperatives in 30 states offer community solar programs.

1. Boone County 2. Champaign County
   
   

- March 27, 2018: Zoning Board of Appeals considered documents in connection with proposed solar ordinance and special-use permits, including study on property value appraisals; study on health and safety impacts of solar PVs; decommissioning estimate; information from Farm Bureau; and solar ordinances from McHenry, Iroquois, Kankakee, and DeKalb Counties

- July 5, 2018: County Board Environment and Land Use Committee approved for 30-day review period a proposal to amend zoning ordinances for solar farms; no solar farm would be allowed within any contiguous urban growth area or within a half-mile of any zoned municipality, except as may be necessary to connect to an existing electrical substation; protections to existing drainage district tiles; if decommissioned, land must be reclaimed for agricultural use; seven solar farm applications pending

- On August 23, 2018, the Champaign County Board approved an amendment to the county zoning ordinance to allow solar farms on certain agricultural properties.  Seven applications to build solar farms were previously submitted to the county and will require special use permits.

- Among other provisions, the solar zoning ordinance  states that:

  • The applicant shall file a decommissioning and site reclamation plan with an irrevocable letter of credit in the amount of 150 percent of an independent engineer’s cost estimate to complete the work.
  • Subject to exceptions, the solar farm must be located at least 1.5 miles from an incorporated municipality that has a zoning ordinance.
  • The applicant shall apply for consultation with the Endangered Species Program and the State Historic Preservation Officer of the Illinois Department of Natural Resources.
  • The solar farm “shall be located, designed, constructed, and operated so as to avoid and if necessary mitigate the impacts to wildlife to a sustainable level of mortality”.
  • Cabling must protect agricultural drainage tile, with minimum depth of 5 feet below grade.
  • Topsoil must be retained and a vegetative ground cover must be established in the solar farm.

- On December 10, 2018, Urbana's City Council voted in favor of "A Resolution Approving an Option to Lease and a Ground Lease of Urbana Landfill Complex" covering 41 acres in a closed landfill.

3. Cook County 4. Danville

City of Chicago, et al. – 2017

Cook County joined the Solar Market Pathways project and received $1.2 million in federal funding to help bring community shared solar power to the area. The goal is to develop five to seven community solar demonstration sites within the county. The grant provides design, solar assessment and technical, and financial feasibility analysis.  On financial returns: 

Our fifteen case studies show that community solar projects can be financially viable in many typical settings within Cook County: with commercial, nonprofit, or government host sites, from 2 megawatt (the maximum allowed by law) down to as small as 100 kilowatt, and on settings as varied as open land, schools, churches, and even landfills.

Cook County's Community Solar website provides various documents of analysis reports, case tools, value proportions, and work plans. The analyses will address the barriers, solutions, and next steps for community solar in Cook County.

Decommissioning plan required when applying for a use permit, bond must be posted, and decommissioning must be completed within 6 months after operations cease

Ordinance

Plans were announced on February 8, 2018 to develop a project with about 7,000 solar panels on private farmland.  The landowners sent a request for approval of the project to the Knox County Zoning Board of Appeals.  However, neighbors objected at a community open house on February 19, 2018, and the landowners rescinded the request for the project.

On September 26, 2018, the County Board granted conditional use permits for four community solar projects, each of 2 MW on 15 to 20 acres.  Each project would generate about $20,000 annually in property taxes.  The estimated cost of decommissioning was $25,000 per MW.

In February 2018, the LaSalle County Board approved petitions for special use permits for two solar farms on privately owned farmland. 

The conditions for the special use permits include: providing a cost estimate of decommissioning and a sufficient surety bond; submitting a report on existing subsurface agricultural drain tiles and repairing all field tiles damaged in constructing the solar farm; maintaining the site, including annually submitting a report to the Environmental Services and Land Use Department an equipment maintenance and controlling noxious weeds and drainage; providing area residents with a phone number to call with project related questions and/or issues, and promptly responding to and resolving issues; and contacting the applicable township road commissioner regarding site access plans, road use, and need to secure an entrance permit.
15. Lee County 16. Madison County

- December 19, 2017: Adopted Solar Farm Ordinance with setbacks of 50 feet in an agricultural district and 300 feet from a residence, and liability insurance naming the County as an additional insured (limits at least $2 million per occurrence and $5 million in aggregate)

- May 4, 2018: Zoning Board approved a 2 MW solar farm on about 10 acres in Marion Township

On January 3, 2019, the Madison County Government Planning and Development Committee approved with conditions a special use permit for a 2 MW solar project on 17 acres zoned Agriculture District in Worden.  The Staff recommended approval, noting: “The impacts of the proposed special use permit should be minimal considering the density of development within the immediate area, and the use will not conflict with surrounding agricultural and commercial land uses. The proposal will provide Madison County residents the opportunity to purchase an affordable source of solar energy without installing individual panels on their property, which is not an option for many property owners.”  However, the Committee denied petitions for special use permits for 2 MW solar projects in Hamel (with one member noting the close proximity to the village and homes) and St. Jacob (with the mayor stating that community solar projects do not fit in the village’s Comprehensive Plan).

17. Marshall County 18.  McHenry County

County Board zoning approval on March 8, 2018, for two community solar projects on "dry corners" of non-irrigated farmland.

On 22 acres of one farm, a 2 megawatt project.  On a second farm, a 1.6 megawatt project on 12 acres and a separate 1 megawatt project on 8 acres. 

Construction scheduled for 2019.

County approved solar energy ordinance on April 13, 2017.  See especially Section 4.24 of the Zoning Ordinance, including provisions for a decommissioning plan and financial assurance of adequately performing decommissioning.

July 19, 2018: Zoning Board of Appeals approved special use permits for solar farms in Lacon and Sparland areas, and expansion of a permitted site outside Henry; developer of site near airport will commission a glare study

June 15, 2018: at least ten solar farm proposals submitted for approval, including a plan for a 2 MW project leasing 16 acres of farmland for a 20-year term with options to renew and paying about $1,300 per acre annually.  Staff report for June 21, 2018 hearing on one proposed project:

STAFF ASSESSMENT The 2030 Comprehensive Plan and the 2030 and Beyond update to the plan both support the development of solar farms. After construction, there is very little to no traffic generated by the use. There is no noise, lighting, or any other nuisances anticipated from this use. The proposed use is compatible with adjacent agricultural uses. While not required, screening the facility would limit any potential visual impacts to the adjoining residences to the north and east. The property in question does not contain any FEMA floodplains, floods of record…. The petitioner has indicated that there will not be any grading of the site and new impervious surfaces will be at a minimum. It is recommended that the woodland acres be excluded from the conditional use area to ensure that this remnant oak woodland is protected. All construction will be required to meet all applicable codes and ordinance for fire protection, commercial building and electrical construction, and stormwater management. Staff recommends adding conditions regarding low-growth native vegetation and noxious weed control to benefit natural pollinators and provide for a more aesthetically pleasing site. Staff also recommends adding conditions regarding decommissioning and bonds to ensure the land can be returned to agricultural operations.

19.  McLean County 20. Mercer County

County board approved three projects in February 2018.   Each solar project will have capacity of 2 megawatts, be located on about 20 acres, and require a total investment of $3.9 million.

23.  Piatt County 24.  Rock Island County

In November 2018, the Piatt County board voted down applications for two permits for solar farms.  One proposed project for 2 MW on 37 acres would have been near ten homes.  The other project would have been for 4 MW on 47 acres; residents raised issues including drainage and saving farmland. 

The developer seeking the 4 MW project re-applied for a permit in December 2018, proposing a location further from a residence and with about 3,500 to 4,000 feet of upgraded and new drainage tile that would help neighboring farms.

In January 2019, the Piatt County board approved special use permits for three solar projects – 3.2 MW on 30 acres, 4 MW on 47 acres, and 4 MW on 37 acres.

July 27, 2018: County Zoning Board of Appeals approved special-use permit for 30 acre solar project on farmland
25.  Saint Clair County 26.  Sangamon County

July 27, 2018: Zoning Board gave preliminary approval for four solar projects on farms, with other proposals pending

29.  Woodford County  

A developer seeking a permit to construct a 2 MW solar farm in Eureka received a favorable recommendation from the Woodford County Zoning Board twice.  However, some residents asserted that solar project would not be aesthetically pleasing and would reduce property values; the mayor stated that the project would be in the fastest growing neighborhood of Eureka.  The Woodford County Board rejected the application twice

The developer filed a lawsuit claiming that its applications complied with all county requirements.  On January 17, 2019, the county circuit court ruled in favor of the developer’s request for a special zoning exception to construct the solar project on 25 acres.
