Stem PowerTrack™ Scales Norbut Solar Farms’ Community Solar Development and EPC Growth

Technology standardization drives Norbut EPC expansion while streamlining operations across 50 MW portfolio

HOUSTON--(BUSINESS WIRE)-- Stem (NYSE: STEM), a global leader in AI-enabled clean energy software and services, today announced that Norbut Solar Farms (NSF), a leading community solar developer in the New York ISO (NYISO) power market, will standardize on Stem’s PowerTrack™ software to scale and manage its growing portfolio of solar projects. The collaboration will enable NSF to accelerate its Engineering, Procurement, and Construction (EPC) strategy, bringing more clean energy projects online while enhancing operational efficiency and streamlining critical reporting processes.

NSF has deployed more than 525 MW of community solar and 30 MW of energy storage across New York State, and is expanding with 17 new projects planned over the next three years. To help advance this strategy, NSF is standardizing on Stem’s PowerTrack™ software totaling 50 MW over a five-year term. The transition is expected to empower NSF with a more scalable, data-driven approach to commissioning and managing its assets, ensuring rapid project execution and seamless integration across its operations. PowerTrack™ is enabling NSF’s stated long-term vision to execute its own EPC work on projects, ensuring seamless integration from origination through construction.

“As we continue to scale, the move towards standardizing on PowerTrack™ has helped us simplify our development approach and accelerate project deployment,” said Rick Allen, President, Norbut Solar Farms EPC. “Stem’s technology provides real-time insights, custom reporting, and automation that enable us to efficiently manage multiple projects while supporting our long-term EPC growth. Their ongoing energy expertise from project inception to ongoing operation has been invaluable.”

NSF strategically structured its projects into four co-located arrays forming a complete site. This approach ensures that each array operates independently while keeping total system capacity under 5 MW AC, allowing for more efficient deployment and streamlined integration into the grid. In addition to commissioning, monitoring, and controlling solar and storage assets, PowerTrack™ provides real-time fault detection, long-term trend analysis, and tailored compliance reporting to regulatory bodies such as New York State Energy Research and Development Authority (NYSERDA) for incentive or Solar Renewable Energy Credit (SREC) reporting, as well as seamless integration with data agents that support these reporting processes. These capabilities allow NSF to track and optimize system performance while promoting compliance with evolving market requirements.

“Norbut Solar Farms is leading the transformation of New York’s community solar and storage landscape through innovative EPC solutions,” said Matt Tappin, President of Software, Stem. “Our collaboration demonstrates how advanced software can amplify the impact of visionary developers like NSF. By streamlining their EPC execution and providing unprecedented portfolio visibility, we're helping NSF deliver clean energy solutions more efficiently while advancing their commitment to community-focused sustainability. This work exemplifies Stem's mission to accelerate the clean energy transition through technology-enabled partnerships.”
