The Opus Group designs the path that connects generation to the grid — utility-scale solar and storage, the substations that step them up and interconnect, and the transmission that delivers. One firm, one engineering language, from the array to the point of interconnection and beyond.
Utility-scale PV and battery storage plant design: buildable area, layout, electrical, energy yield (P50/P90/P95), and a bankable financial model. Headless engine, traceable to formula and datasheet.
Solar + BESS →Step-up and switching stations to the point of interconnection: single-line, general arrangement by clearances, grounding to IEEE 80, bus and conductor sizing, civil and structural. Protection studies by the utility.
Substations →The line that delivers: route and structure engineering, conductor and clearance, interconnection support.
Transmission →A power plant doesn't end at the array — it ends at the grid. Most projects hand generation, the substation, and transmission to three different engineering teams: three interfaces, three sets of assumptions, three places for the design to drift. The Opus Group holds the whole path — the same engineering language from the first table to the last span of line. Fewer interfaces. One source of truth.
Every number traces to a formula or a datasheet. Our solar practice runs on an in-house headless engine that takes a site boundary to a bankable design package — buildable area, layout, electrical, P50/P90/P95 energy, and a financed pro forma — with the workings retained and auditable. Engineering you can check, not a black box.
