Utility-Scale Solar & Battery Storage Engineering
From utility-scale PV design and BESS integration through construction drawing sets, interconnection packages, and financial modeling — TekMinds provides the full-spectrum engineering, project, and analytics support that Solar Developers, EPC Contractors, and Storage teams need to move fast and build right.
Solar developers and IPPs need engineering partners who move at development speed. TekMinds embeds directly into your project team to deliver PV design packages, energy models, interconnection application support, and investor-ready financial models — on schedule and within development budgets.
Full MISO interconnection application package including generation facility study inputs, site control documentation, site plan, SLD, and technical data sheets for inverters and transformers. Submitted within 8 business days of NTP.
Full 25-year project pro forma with LCOE calculation, equity/debt return analysis, PPA sensitivity scenarios, and a dynamic assumptions dashboard with scenario manager for three interconnection cost cases.
P50/P90 energy yield models for a 4-project, 100 MW portfolio using PVSyst with site-specific irradiance data, soiling loss analysis, bifacial gain modeling, and a consolidated lender-ready summary report.
EPC contractors need engineering output that field crews can actually build from and AHJs will approve on the first submission. TekMinds provides construction drawing sets, submittal packages, scheduling support, and estimation services calibrated to tight bid windows and tighter construction schedules.
Full construction drawing set including SLD, 3-line diagrams, DC collection layout, AC underground routing, grounding & bonding, site civil grading plan, and O&M building electrical plans. Delivered in 3 weeks across a team of 4 engineers.
Detailed material and labor cost estimate covering DC/AC balance of system, civil earthwork, electrical equipment, and labor productivity assumptions — delivered 4 days before bid deadline with alternates and exclusions formatted for owner submission.
Primavera P6 baseline construction schedule with activity-level detail for civil, electrical, mechanical, and commissioning phases, plus a 3-week rolling look-ahead updated weekly for the project management team and owner's engineer.
Battery energy storage projects require specialized electrical, structural, and grid-integration expertise that most engineering firms don't have on staff. TekMinds provides BESS electrical design, protection and relay coordination, structural design, and grid interconnection support for standalone and co-located solar+storage projects of all scales.
Full electrical design package including SLD, 3-line diagram, protection relay coordination study, SCADA communication architecture, and grounding design. Coordinated directly with the PCS and BMS vendors for interface documentation.
Electrical integration design for a co-located PV and BESS project in CAISO, including combined SLD, common coupling point design, interconnection equipment sizing, and coordination of BESS charge/discharge profiles with solar generation modeling.
Revenue stacking model combining ancillary services (ECRS, RRS), energy arbitrage, and capacity payments, with battery degradation curves, a 20-year cash flow model, and sensitivity analysis across three market price scenarios.
Development timelines are compressed. Interconnection queues are moving. Construction windows don't flex. Here's how TekMinds fits into that reality.
We can embed a 2–6 person team on your project within days of NTP — no lengthy onboarding, no procurement delays, no bench-warming.
Our engineers have delivered PV design, BESS integration, interconnection packages, and construction drawing sets across utility-scale, C&I, and distributed generation projects.
From PV layout and structural to project finance and compliance documentation — one team, one engagement, all the disciplines your project needs.
Resource-based and project-based engagement models let you scale TekMinds support up or down as your development pipeline demands.
Whether you need PV design support next week, a construction drawing set in 3 weeks, or a BESS integration team for a complex storage project — TekMinds can mobilize fast and deliver work your team can build from.
