Project Overview

Coggon Solar is proposing a 100 MW solar project in north Linn County, Iowa, which will bring jobs, economic growth, and affordable clean energy to the area.

Coggon Solar will be non-permanent, and fully removed and remediated after 35 years. Its undergrowth will be planted as “native prairie,” providing habitat for wildlife and pollinators.

Coggon Solar will generate reliable and affordable electricity for CIPCO’s members for 20 years, serving nearly 20,000 local customers, including those in Linn REC.

The project will support CIPCO’s energy supply, and replace a portion of the retiring Duane Arnold Energy Center.

Coggon Solar will be constructed on private land adjacent to the existing CIPCO Coggon Substation. By utilizing the available capacity at this location, Coggon Solar will provide long-term affordable power to CIPCO’s members.

 FAQs

 
  • No. Coggon Solar will not be detrimental to Existing Agricultural Uses and will likely provide benefits to surrounding owners.

    Prior to construction, the site will be planted with a cover crop like when fields are rested on crop rotations. Post construction, Coggon Solar will be planted as “native prairie” and will be actively monitored and managed throughout the project life to ensure the health and condition. As described in the vegetation management plan, the project will be managed using little to no herbicides. Further, the project will include wildlife friendly fencing that is gapped at the bottom. This will allow small mammalian and avian species to use the site as habitat and protection, increasing the prey base that supports the entire local ecosystem.

  • No, Coggon Solar’s temporary use of the site will remove 0.2% of all agricultural land in Linn County, which was described by a member of the Linn County Planning & Zoning Commission as a “drop in the bucket”.

    Coggon Solar is replacing one energy feedstock with another, swapping corn and tractors for sun rays and solar panels. 100% of the energy produced by Coggon Solar will be consumed in Iowa for a minimum of twenty years, providing clean affordable power without variable fuel costs.

  • No, the solar panels used for the Coggon Solar project do not contain any hazardous materials. Coggon Solar will employ Tier I UL rated solar modules. The primary components are monocrystalline silicon wafers, copper based electric wiring and substrates, and tempered glass. The Bill of Materials used to manufacture the modules selected for the Coggon Solar project has been provided to Linn County Staff. A Verification Report of the modules states that levels of hazardous chemicals that may occur in the modules comply with the limits as set by RoHS Directive (EU) 2015/863 amending Annex II to Directive 2011/65/EU. RoHS standards are more stringent than U.S. RCRA standards for hazardous chemicals.

  • 325,000 solar modules will be installed. Approximately 38,000 piers will be installed. Each pier has a surface area of 100 sq/In. The total surface area of all the piers is approximately 26,389 sq/ft or 0.61 acres which equates to less than 0.5% of the Project site. The piers will be machine driven and will not require concrete foundations.

  • In the unanticipated event that solar modules were blown onto adjacent properties in a high wind event, Coggon Solar would be responsible for their removal and clean up, and would present a plan to do so to Linn County 72 hours after the storm event.

  • Coggon Solar will repair or reroute any tiles that are damaged during the construction or operation of the project facility. In the Agricultural Mitigation Plan (AMP) submitted to the County as part of its Renewable Energy Overlay zoning application, Coggon Solar outlined a comprehensive plan to address the presence and treatment of drain tile before, during, and after construction.

  • 100% of Coggon Solar’s energy generation is being purchased by Central Iowa Power Cooperative (CIPCO) for the first 20 years of operation. CIPCO is a 501(c)(12) not for profit entity that purchases power on behalf of 13 rural electric cooperatives in Central Iowa, including Linn County REC, which serves more than 30,000 customers. The project will generate enough electricity annually to power 18,000 typical Iowa homes.

    After 20 years, it is anticipated that the project would continue to sell power to CIPCO or another utility via the Midcontinent Independent System Operator (MISO) marketplace.

  • The Coggon Solar site is adjacent to the CIPCO Coggon Substation which was identified as having no network upgrades to inject 100MW of new capacity. This fact minimizes the costs paid by CIPCO’s members and enables CIPCO to lock in a local low-cost energy source for 20 years. The Coggon Substation is near CIPCO’s load in Cedar Rapids, which reduces energy losses on the transmission system and increases reliability – both of which further benefit consumers.

    Coggon Solar was also able to identify and enter into an agreement with enough contiguous landowners to build a 100MW project immediately adjacent to the Coggon Substation. This element further diminishes project costs as it does not require a costly generation tie-line.

    Coggon Solar conducted extensive site due diligence on the subject parcels prior to submitting its REO zoning application and determined the project would have little to no impact on environmental or cultural resources and would only be immediately visible to approximately eight non-affiliated residences.

  • Unfortunately, no. Coggon is the only viable location for a CIPCO solar project in Linn County without a higher financial burden on the rate payers of Linn County.

  • Yes, Coggon Solar is committed to hiring locally and being an economic engine locally during both construction and operations. To target local workers, Coggon Solar and its contractors are committed to the following:

    · All contracts for construction, operations, goods and services will be advertised within Linn County

    · Project labor will be recruited from Linn County to the maximum extent feasible, including the placement and wording of advertisements and competitive bidding opportunities with applicable local trade organizations and other labor contractors

    · All other factors being equal, opportunities for local contractors, firms, and individuals whose primary place of business is located within or residing in Linn County will be given

    Coggon Solar conducted a third-party Economic Impact Analysis that concluded the following:

    · Over 139 new local jobs during construction

    · 247 new local jobs during construction for the state of Iowa

    · Over 5.7 new local long-term jobs for Linn County

    · Over $16.9 million in new local output during construction for Linn County

    · Over $30 million in new local output during construction for the State of Iowa

    · Over $750,000 in new local long-term output for Linn County

    · Over $3.7 million in property taxes in total for all taxing districts over the life of the project

    · Over $2 million in total school district revenue over the life of the project

    Most of the local spending during construction occurs at local businesses such as hardware stores, hotels, gas stations, restaurants, rental agencies, etc. that greatly benefit the immediate community.

  • Yes, Coggon Solar is committed and contractually obligated in its leases to fully restore the Project Site to its pre-project condition. Coggon Solar has hired a third-party engineer to estimate the cost of decommissioning. Coggon Solar will put a $1 million security in place upon completion of construction to provide financial assurance of decommissioning. The engineer determined that the value of the system would outweigh the decommissioning cost until approximately year 23 of operation. The decommissioning plan submitted to the county details how the cost and value estimates of the plant and decommissioning will be periodically updated to ensure appropriate financial assurance is in place to cover the cost of decommissioning.

  • Clēnera was founded by Jason Ellsworth and Adam Pishl in Boise, Idaho in 2013. In August 2021, a 90% interest in Clēnera was purchased by Enlight Renewable Energy LTD, a publicly traded company based in Tel Aviv, Israel. Clēnera continues to be managed by Jason Ellsworth and Adam Pishl from its Idaho headquarters.

    The Clēnera acquisition by Enlight, including the acquisition of the Coggon Solar project, was reviewed and approved by the Committee on Foreign Investment in the United States (CIFIUS).

    The project will be financed through a combination of equity and debt. While the specific sources of funding are still being finalized, it is important that Clēnera maintains strong relationships with multiple financial institutions including US Bank, M&T Bank and Wells Fargo. To date, Clēnera has financed 1.3 GW of solar projects across the U.S.

  • Coggon Solar will not have an adverse impact on property values. Coggon Solar commissioned a third-party adjacent property value impact report conducted by a team of certified appraisers that looked at a growing body of research, including 26 studies in 15 states that demonstrated empirical evidence that solar installations have no impact on property values.

    The study interviewed over 40 county and township Assessors in midwestern states all of whom have at least one installation in their jurisdiction, and all determined that solar installations have not negatively affected adjacent property values.

  • No. There is an emerging body of focused research on the subject that strongly suggests that the “lake effect hypothesis” is incorrect and has no correlation to waterfowl attraction or mortality.

    Clēnera also conducts avian monitoring programs at two of its operating projects, the 80MW Sweetwater Solar project in Wyoming and the 200MW Wright Solar Park in central valley California. Sweetwater Solar had avian monitoring from 2018 through 2021 when no waterfowl were identified at the site and only one avian mortality was reported during that time. Interestingly, the population of sage grouse in the vicinity of the project flourished as the grouse were using the arrays as protection from predatory species. Wright Solar has been under avian monitoring since 2019, and to date, only one avian fatality can be attributed to the installation that spans 1,600 acres. Despite an approximate [1,000] acre reservoir being less than a mile south of the project, and a [5,000] acre reservoir 6 miles north, no waterfowl have ever been identified at the Wright Solar project. Documentation can be provided upon request.

[Wapello Solar] is an important source of energy for our member-owners. With our mission of providing wholesale power and services in a safe, reliable, and cost-effective manner, the completion of this project helps meet member expectations.
