San Francisco, CA, January 29, 2026 – Power Factors, the leading renewable energy management suite (REMS) provider, has been named the #1 Energy Management System (EMS) and Monitoring & Control (M&C) provider in the utility-scale energy storage industry by Guidehouse Research in its latest Leaderboard: Renewables and Energy Storage Systems Monitoring & Control report.
The achievement recognizes Power Factors’ leadership in vendor-agnostic EMS technology, comprehensive monitoring and control capabilities, and strong market presence in utility-scale renewables and energy storage. Guidehouse Research ranked Power Factors first overall based on its differentiated technology, market share, geographic reach, and go-to-market execution.
Core technology differentiators for Power Factors identified in the report include vendor-agnostic integration, advanced AI- and machine-learning–driven forecasting, and purpose-built analytics for battery energy storage systems (BESS) and hybrid assets. The report notes that “Power Factors continues to advance its monitoring and control and EMS offerings with highly interoperable solutions, scalable cloud architecture, and embedded intelligence,” highlighting the company’s ability to support increasingly complex hybrid renewable portfolios at scale.
Power Factors’ market leadership is reflected in real-world deployment at scale. The company provides monitoring and control for more than 20 GW / 40 GWh of battery storage capacity, alongside more than 75 GW of total SCADA and EMS projects globally. With over 340 GW of renewable energy assets managed across 70+ countries and 600+ utility-scale customers, Power Factors demonstrates one of the broadest geographic footprints in the monitoring and control market.
Guidehouse Research also recognized that Power Factors’ monitoring and control leadership is grounded in a strong strategic foresight and an integrated platform approach. The report notes that “Power Factors has a well-conceived vision for its place in the monitoring and control market, as well as a strong go-to-market strategy score because of its comprehensive, integrated Unity platform that is scalable by portfolio size.”
The Unity Renewable Energy Management Suite (REMS) brings together SCADA, EMS, PPC, asset performance management, operations and maintenance, and commercial asset management in a single, scalable platform designed to support portfolios as they grow in size and operational scope. This integration allows asset owners and operators to standardize operations, reduce integration complexity, and confidently scale hybrid and storage-heavy portfolios.
“Being named the number one EMS and M&C vendor by Guidehouse Research is a clear validation of the work our expert team and market-leading customers have done together,” said Julieann Esper Rainville, CEO of Power Factors. “We’ve built these solutions to operate across markets, technologies, and grid requirements, without locking customers into proprietary hardware or closed ecosystems. Our customers trust us to operate some of the world’s most complex renewable and storage assets, and this recognition is a reflection of those capabilities.”
As utility-scale solar, wind, and energy storage continue to converge, operators face mounting complexity in managing hybrid portfolios across diverse markets.
