Complete civil packages for utility solar across Missouri: clearing, mass grading, access roads, collection trenching, SWPPP, fencing, and substation civil.
Backwell is a civil site work general contractor serving utility solar EPCs building in Missouri. We contract complete civil packages: clearing, mass grading, access roads, trenching and underground utilities, erosion control and SWPPP, fencing, and substation civil, all under one contract with Backwell field leadership on site.
Missouri utility-scale solar is scaling quickly from a small base, and Ameren Missouri is the primary driver. The 300 MW Split Rail Solar project in Warren County, acquired from Invenergy, carries a 2026 in service date, and the 50 MW Bowling Green Renewable Energy Center in Pike County was approved in the same 2024 order. In May 2026 the Missouri Public Service Commission approved the 250 MW Reform Renewable Energy Center in Callaway County, which Ameren expects to complete by 2028, and later that month Ameren filed case EA-2026-0183 seeking additional solar and battery capacity including 175 MW next to Huck Finn in Audrain and Ralls counties and 225 MW in Stoddard County. On the western side of the state, Evergy Missouri West began construction of the 107 MW Foxtrot Solar Energy project in Jasper County in late 2025 with completion scheduled for 2027. Arevon's 430 MWdc Kelso Solar Project in Scott County reached operations in March 2026, and Arevon stated it nearly doubled the state's solar capacity.
Solar EPCs and developers usually search by the county or the nearest town to the site. These are the Missouri markets we cover:
We price the package as one scope under one contract, so the EPC has a single point of responsibility for the civil critical path instead of managing separate clearing, earthwork, and utility subcontracts.
Backwell superintendents, project managers, and lead operators run every site. We mobilize company equipment for the core scope and scale each project with leased production fleets, qualified regional subcontractors, and agency-placed field staff, all under Backwell supervision and a single contract.
Contractor licensing. Missouri has no statewide general contractor license and no state commercial building license, so there is no single state card to pull for civil sitework. Licensing and registration are handled at the city and county level, and the requirements vary: larger jurisdictions such as Kansas City, the City of St. Louis, St. Louis County, and Springfield require local contractor registration or a business license, while many rural counties that host solar sites have no contractor licensing at all. What rural solar counties do require is land use approval, typically a conditional use permit or special use permit from the county commission or planning and zoning body, plus a road use or haul route agreement with the county highway department. Practical qualification for a solar EPC in Missouri therefore turns on insurance limits, experience modification rate, equipment fleet, and prequalification packets rather than a state license number.
Construction stormwater. Construction stormwater in Missouri is permitted by the Missouri Department of Natural Resources, Water Protection Program, through a Missouri State Operating Permit for land disturbance issued under the Construction or Land Disturbance Master General Stormwater Permit, permit number MORA00000. Coverage is required for any construction activity disturbing one acre or more, or disturbing less than one acre when it is part of a larger common plan of development or sale that will cumulatively disturb one acre or more. The core requirement is a Stormwater Pollution Prevention Plan, or SWPPP, with site specific best management practices to limit soil exposure, erosion, and pollutant discharge. Note that the MO-R100000 area wide land disturbance general permit is a different instrument, available only to a city, county, state or federal agency, or other governmental jurisdiction, and is not the permit a private solar project or its contractor uses. Source: https://dnr.mo.gov/water/construction-or-land-disturbance-master-general-stormwater-permit-mora00000 Backwell carries the SWPPP scope, installs and maintains the controls, keeps the inspection log, and closes the permit out with final stabilization.
Prevailing wage. Federal Davis-Bacon prevailing wage rates apply on their own terms through the Inflation Reduction Act: solar projects with a maximum net output of 1 MW AC or greater must pay Davis-Bacon prevailing wages to laborers and mechanics and meet apprenticeship labor hour and ratio requirements in order to claim the full value investment or production tax credit. Essentially every project on this list clears that 1 MW threshold, so certified payroll and apprenticeship tracking should be assumed on all of them. On top of the federal requirement, Missouri has its own state prevailing wage law under Chapter 290 of the Revised Statutes of Missouri, administered by the Missouri Department of Labor and Industrial Relations, Division of Labor Standards, which issues annual wage orders by county and occupational title. The state law reaches public works construction for a public body, so privately owned developer solar is generally outside it, but work for a municipal utility, a public power district, or any publicly owned or publicly funded portion of a project can trigger state prevailing wage and state certified payroll on top of the federal obligation. For projects claiming the full ITC or PTC, Backwell produces Davis-Bacon certified payroll, pays the applicable wage determination, and supports apprenticeship labor-hour compliance.
