Complete civil packages for utility solar across New Mexico: 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 New Mexico. 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.
New Mexico utility-scale solar work in the 2026 to 2028 window is concentrated in two clusters: the Four Corners area of San Juan County, where solar and storage is being built on and around the retired San Juan Generating Station site and tied into PNM's grid, and the southern border corridor in Doña Ana and Luna counties, where El Paso Electric has contracted a series of solar plus storage facilities. Data center load is a direct driver: the Four Mile Mesa project in San Juan County is contracted through PNM to serve Meta's operations, and the TAG Solar project in Sandoval County was built to serve Meta's Los Lunas campus. PNM's June 2026 resource filing seeks roughly 1,650 MW of new renewable and storage capacity, including a utility-owned solar and storage project in the Four Corners region and two 150 MW battery projects in Bernalillo County targeted for late 2027 and early 2028. The SunZia 500 kV transmission line, which originates at a substation in Torrance County and is now in service, plus the proposed RioSol line, are the transmission backbone that additional central and southern New Mexico generation is expected to follow. Most of the near-term buildout pairs solar with four-hour battery storage, which means the civil scope typically includes both a PV array pad and a separate BESS pad, access roads, and collection trenching.
Solar EPCs and developers usually search by the county or the nearest town to the site. These are the New Mexico 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. Yes. New Mexico requires a contractor license issued by the Regulation and Licensing Department, Construction Industries Division (CID), for work meeting the statutory definition of a contractor. Commercial civil sitework is generally carried out under the GB-98 general building classification for commercial and residential building work, or under the GA series for heavy and highway type work, where GA-98 covers asphalt, bitumen and concrete construction and carries the authority of the GA-1 through GA-5 classifications. A qualifying party must sit for the applicable trade and business and law exams, and a contractor bond, currently 10,000 dollars, is required before CID will issue the license. An out of state contractor should confirm the exact classification match for its scope, earthwork, grading, trenching, roads and foundations, directly with CID before bidding, since the classification map is scope specific.
Construction stormwater. New Mexico is not an authorized NPDES state. The U.S. Environmental Protection Agency, Region 6 in Dallas, is the NPDES permitting authority for all facilities in New Mexico, so construction sites disturbing one acre or more are covered under the federal EPA Construction General Permit (CGP), with a SWPPP prepared and a Notice of Intent filed through EPA's electronic NOI (eNOI) system. The New Mexico Environment Department Surface Water Quality Bureau, Point Source Regulation Section, performs compliance inspections on behalf of EPA and handles Clean Water Act Section 401 certification, and reports go back to EPA Region 6. New Mexico legislation has given NMED statutory authority to move toward a state administered NPDES equivalent program, so contractors should confirm at bid time whether the federal CGP or a newly effective state permit governs the specific site. 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 and apprenticeship requirements apply through the Inflation Reduction Act to projects above 1 MW that claim the increased ITC or PTC rate, which covers essentially every utility-scale solar project in this list, so certified payroll and registered apprentice ratios should be assumed on the civil scope. On top of that, New Mexico has its own state prevailing wage law, the Public Works Minimum Wage Act, administered by the New Mexico Department of Workforce Solutions, Labor Relations Division, which sets wage decisions for public works contracts above the statutory threshold. Privately owned utility-scale solar is generally not a public work under that Act, but it can be pulled in where a public entity, state or local funding, or a public land or municipal utility element is part of the deal, for example projects contracted to a county or municipal offtaker. Confirm with the owner at bid time which wage determination governs, and expect certified payroll reporting either way. 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.
