Directional Boring for Solar Energy Projects in Oklahoma

Oklahoma’s solar energy sector is growing rapidly. Utility-scale solar farms, community solar installations, commercial rooftop solar with underground interconnect, and distributed solar generation are all creating significant demand for underground conduit boring services. Solar energy projects require underground conduit for DC collection circuits between arrays and inverters, AC interconnect conduit from inverters to the point of interconnection, communications conduit for SCADA and monitoring systems, and equipment power for site lighting and security. Directional boring installs these conduit systems beneath roads, drainage features, and natural obstacles that would otherwise require costly open-cut crossings.

Trinity Boring Solutions provides directional boring for solar energy developers, EPC contractors, and electrical contractors working on solar projects across Oklahoma. We bore conduit crossings under public roads for utility-scale solar farms, install interconnect conduit beneath state highways for solar project transmission connections, and perform all the boring work that solar projects require to connect their underground infrastructure.

Oklahoma has excellent solar resources, with high solar irradiance particularly in the western half of the state. Utility-scale solar development has accelerated in Oklahoma, with projects in counties including Caddo, Comanche, Grady, Jackson, Kiowa, Roger Mills, Washita, and others. Rural county roads and state highways that cross solar farm sites require boring permits and professional HDD installation to install the collection conduit that aggregates solar power from distributed arrays to central inverter stations.

ODOT encroachment permits are required for conduit crossings under state highways. County road crossings require permits from county road departments. Trinity Boring Solutions handles the permit application process for solar project road crossings, working with the project engineer and the utility company to obtain all required permits for the project schedule.

Solar project boring work is often performed in agricultural settings with expansive rural Oklahoma landscapes. Access to bore sites across solar farms may require coordinating with landowners and agricultural operations. Our crews are experienced working in agricultural and rural environments and understand the considerations for minimizing land disturbance during boring operations on working farm properties.

Solar Project Boring Services

DC Collection Conduit

Underground conduit for DC collection circuits between solar panel arrays and string inverters or central inverter stations. HDPE conduit in sizes appropriate for the cable conductors and fill ratios specified by the electrical engineer.

Road Crossing Bores

ODOT and county road encroachment permit bores for conduit crossings under public roads bisecting solar project areas. We install conduit bundles sized to carry all collection circuits in a single bore where road crossings are required.

Interconnect Conduit

Conduit for AC interconnect cables from inverters to the project substation or point of interconnection. Boring under highway right-of-way for interconnect conduit avoids costly highway shoulder trenching and pavement restoration.

SCADA and Fiber

Fiber optic conduit for solar project SCADA, monitoring, and communications systems. Boring fiber conduit under roads and drainage features on the solar site connects the data collection network without aerial cable runs.

Drainage Crossings

Conduit boring under drainage ditches, creeks, and swales within solar project boundaries. Boring avoids the permitting and erosion control requirements of open-cut drainage crossings.

Substation Connections

Underground conduit from solar project collection systems to the project substation. Substation connection bores may be large diameter to accommodate the number and size of circuits connecting to transformer and switchgear equipment.

Solar Boring Process

  1. Project Plan Review: We review solar project electrical one-lines, civil plans, and road crossing schedules to identify all bore locations and conduit requirements. Working with the EPC and electrical contractor, we develop a bore sequence that aligns with the project construction schedule.
  2. Road Crossing Permits: For each public road crossing, we prepare and submit encroachment permit applications to ODOT or the applicable county road authority. Permit processing times vary, and we initiate permit applications as early as possible in the project schedule.
  3. OK 811 Locates: We contact OK 811 for utility locates at all bore locations. Rural road crossings on solar project sites often have fewer underground utilities than urban locations, but agricultural irrigation lines, existing electric service, and telecommunications lines may be present and must be located before boring.
  4. Bore Execution: Road crossing bores are performed with appropriate rig size for the conduit bundle diameter and crossing length. Solar collection conduit bores range from simple single-conduit crossings to large multi-conduit bundles that require larger bore diameters and significant pullback force.
  5. Conduit Bundle Installation: Conduit bundles are pre-assembled with appropriate spacers and end caps and pulled through the bore in a single pass where possible. This approach minimizes the number of bores required at each road crossing location.
  6. Documentation: As-built bore locations and depths are documented for the project engineer and for ODOT or county road authority as-built requirements on road crossing permits.

Why Choose Trinity Boring Solutions for Solar Projects

Solar EPC contractors and developers choose Trinity Boring Solutions for Oklahoma solar project boring because of our experience with road crossing permit coordination, our equipment capacity for large conduit bundle bores, and our ability to work efficiently in rural agricultural environments where solar projects are typically located.

We understand solar project schedules and the milestone-driven nature of EPC solar construction. Road crossing bores are often on the critical path for solar farm energization, and we work with the project team to execute bores on the schedule that the project requires.

Frequently Asked Questions

Do solar road crossings require ODOT permits even on rural county roads?

State highway crossings always require ODOT encroachment permits. County road crossings are governed by the county road authority, typically the county engineer. Most Oklahoma counties require a permit or at minimum notification for underground utility crossings of county roads. We determine the applicable permitting authority for each road crossing on the solar project and obtain required permits.

How many conduits can you pull through a single bore at a road crossing?

Multi-conduit bundles of 4 to 12 or more conduits can often be installed in a single bore pass using spacer-assembled bundles. The conduit bundle size must be compatible with the bore diameter, and the bore diameter must be sized for the total bundle OD with a reasonable reaming allowance. We design conduit bundle bore specifications in coordination with the project electrical engineer.

Can you bore under irrigation canals and drainage ditches on solar farm sites?

Yes. Boring under irrigation canals, drainage ditches, and natural waterways on solar farm sites avoids the environmental permitting and erosion control requirements of open-cut crossings. These crossings also avoid potential damage to irrigation infrastructure that open-cut crossing excavation would create.

What conduit material do you install for solar collection systems?

HDPE (high-density polyethylene) conduit is the most common material for solar collection system conduit installed by boring, due to its long service life, resistance to soil corrosion, and compatibility with directional boring installation. Schedule 40 PVC is also used in some applications. Conduit material and size are specified by the project electrical engineer.

How do you handle frac-out prevention near solar project irrigation areas?

Frac-out (escape of drilling fluid from the bore path) is managed by controlling drilling fluid pressure and flow rate relative to soil conditions. In areas near irrigation infrastructure, we use conservative drilling fluid pressure settings and monitor the bore closely for any fluid loss indicators. We have contingency response measures for frac-out events including immediate pumping stoppage and surface containment.

Can you bore for solar projects in western Oklahoma caliche soils?

Yes. Caliche and hardpan soils common in western Oklahoma present greater drilling difficulty than sandy or clay soils. We use appropriate rock-capable tooling and drilling fluids for caliche conditions. Bore progress may be slower in caliche formations, which we factor into our project scheduling for western Oklahoma solar bores.

Do you coordinate with the utility interconnect team on substation bores?

Yes. Substation connection bores require coordination with the utility company’s interconnect team, the substation contractor, and the project EPC. We work with all stakeholders to ensure bore locations, conduit specifications, and installation timing are aligned with the utility company’s interconnect requirements and the project energization schedule.

Can you mobilize quickly for solar projects in remote western Oklahoma counties?

Yes. We mobilize statewide including to remote western Oklahoma locations. Our crew and equipment are based in Yukon and we have performed projects across the state including in western Oklahoma counties. Travel time to remote locations is factored into our project pricing and scheduling.

What boring rigs do you use for solar conduit bundle installations?

We match the rig to the conduit bundle size and bore length required for each solar road crossing. Smaller conduit bores may use mid-size HDD equipment, while large multi-conduit bundle crossings under major state highways require larger bore machines. Our fleet of 10 or more rigs includes equipment appropriate for the range of bore sizes encountered on solar projects.
