Independent power producer (IPP) Energix Renewables has brought its 152MW Border Basin solar project online in Hancock County, Ohio, with the facility now delivering power to the PJM Interconnection market.
The commissioning of the PV plant pushes Energix Renewables’ total US portfolio past 1GW within the PJM market, according to Zvi Tvizer, country manager and COO at Energix Renewables. The company has a further pipeline of 800MW currently under construction.

AI-enabled clean energy software and services firm Stem provided support to the project from conceptual design to factory preparation through commissioning and operator handoff. According to Stem, the project is run with its PowerTrack platform, which provides power plant control, data acquisition and monitoring for the utility-scale PV plant.
Stem’s involvement spanned the project’s conceptual design through to factory testing, with the company’s scope also covering PJM network integration and power plant control systems.
With the PJM Interconnection market continuing to see strong demand for new generation capacity, projects like Border Basin highlight the operational and technical considerations that underpin successful utility-scale solar deployment, from grid integration requirements to long-term asset monitoring and control systems.
Deployment of solar PV in Ohio has been declining since peaking in 2024 at more than 2.5GW. According to data from the trade body Solar Energy Industries Association (SEIA), the state has so far seen more than 500MW installed in 2026. The trade body forecasts 8.1GW of new solar PV in Ohio over the next five years, more than doubling its current installed capacity of 7GW as of September 2026.
“For utility-scale developers like Energix, bringing a project online is only part of the equation. Long-term success depends on reliable operations, clear visibility into asset performance, and the right technical support,” said Matt Tappin, president of software at Stem.
The commissioning of the Border Basin project follows a module supply agreement Energix signed with Chinese leading module manufacturer Trinasolar last month. Under the agreement, the Chinese manufacturer will supply 580MW of solar modules and mounting systems for Energix projects in Europe. That deal covers Trinasolar’s Vertex N G3 dual-glass TOPCon modules alongside its FixOrigin fixed-tilt mounting systems.
