PowerGEM Secures Strategic Growth Investment from General Atlantic and Announces Acquisition of Telos Energy
PowerGEM, LLC has announced a major milestone in its growth strategy after securing a strategic investment from General Atlantic through the firm’s climate-focused BeyondNetZero fund. Alongside the investment, the company also revealed the acquisition of Telos Energy, a specialized engineering consulting firm known for its expertise in power system analysis, integrated resource planning, and energy market forecasting. The twin developments position PowerGEM to accelerate its role in helping modernize the North American power grid at a time of historic transformation across the energy sector.
General Atlantic’s BeyondNetZero platform, which focuses on businesses advancing the global energy transition, will join existing investor TA Associates in supporting PowerGEM’s long-term expansion plans. TA Associates first invested in the company in 2024 and has since backed several strategic initiatives designed to broaden PowerGEM’s capabilities and market presence.
The announcement comes at a pivotal moment for the electricity industry. Utilities, grid operators, renewable developers, and policymakers are facing mounting pressure to modernize aging infrastructure, integrate increasing volumes of renewable generation, and maintain grid reliability amid rapidly growing electricity demand. The combination of advanced analytics, market intelligence, and engineering expertise is becoming increasingly essential as stakeholders navigate this evolving landscape.
For more than 25 years, PowerGEM has served as a critical technology and services provider to the North American power industry. The company supplies advanced simulation software and technical advisory solutions that are widely used across the energy ecosystem. Its customer base includes every U.S. power system operator, major electric utilities, power producers, renewable energy developers, energy traders, and engineering consultants.
PowerGEM’s software tools help organizations make mission-critical operational and planning decisions. These include short-term market operations, transmission planning, generation forecasting, grid reliability assessments, and long-term infrastructure investment strategies. As the energy transition accelerates, the demand for sophisticated modeling and simulation capabilities has increased significantly.
The company has also been expanding the use of artificial intelligence within its product suite. By leveraging AI-enabled technologies, PowerGEM aims to improve forecasting precision, strengthen scenario and risk analysis capabilities, and simplify how engineers and analysts interpret complex energy data. These capabilities are becoming increasingly important as energy systems grow more decentralized and dynamic.
Joe DeMatteo, Chief Executive Officer of PowerGEM, said the investment and acquisition represent a major step forward for the company as it enters its 26th year in business.
According to DeMatteo, the power sector is experiencing unprecedented change driven by grid modernization initiatives, growing electrification trends, and the integration of new energy resources. He emphasized that PowerGEM is scaling its platform to help customers navigate this increasingly complex operating environment.
He noted that General Atlantic’s addition as a strategic partner will support the development of a more integrated platform that combines grid reliability analysis with market economics. This unified approach is intended to provide customers with clearer and more actionable insights when making high-stakes investment and operational decisions.
DeMatteo also highlighted the company’s broader mission to support the modernization of the electric grid while accelerating the deployment of cleaner and more resilient energy systems. He praised PowerGEM’s employees for their role in advancing technologies that can help improve energy reliability, efficiency, and system flexibility.
The investment arrives at a time when electric utilities and developers are facing mounting infrastructure challenges. Aging transmission networks, rising electricity demand from data centers and electrification, and the rapid growth of renewable generation are creating new operational complexities for grid operators.
At the same time, interconnection queues across the United States have expanded dramatically as developers seek to connect solar, wind, battery storage, and other clean energy projects to the grid. These dynamics have increased the need for more advanced planning tools capable of evaluating system reliability, market impacts, and infrastructure constraints simultaneously.
PowerGEM’s integrated platform is designed to address these challenges by combining transmission and generation planning with sophisticated market analysis. The company believes this approach can help customers bring new energy capacity online faster and more cost effectively without compromising reliability standards.
With support from General Atlantic and TA Associates, PowerGEM plans to accelerate product integration efforts, expand the use of AI-enabled analytics across its offerings, and pursue additional acquisitions that strengthen its capabilities across the energy value chain.
Wilson Bowen, Managing Director at General Atlantic, said the firm sees PowerGEM as an important player within the evolving energy ecosystem.
Bowen stated that PowerGEM’s technologies are deeply embedded throughout the U.S. power sector and that the company has developed a strong reputation for its expertise in grid engineering and market operations. He noted that the company’s simulation tools, technical advisory services, and long-standing customer relationships provide a strong foundation for future growth.
He also emphasized that General Atlantic believes PowerGEM’s platform can play a critical role in helping modernize grid infrastructure and improve operational decision-making as the industry transitions toward cleaner and more distributed energy resources.
TA Associates also reaffirmed its commitment to PowerGEM’s long-term strategy. Charles Ha, Director at TA, said the energy industry is undergoing a once-in-a-generation transformation and that PowerGEM is well positioned to help customers manage the associated challenges.
Ha noted that the company’s products and services are increasingly valuable as utilities and developers navigate the transition toward a more complex and decarbonized electricity system. He added that TA looks forward to collaborating with General Atlantic to support PowerGEM’s continued expansion and innovation efforts.
Since TA’s initial investment in 2024, PowerGEM has pursued an aggressive growth strategy centered on product innovation and strategic acquisitions. The company has completed four acquisitions aimed at expanding its expertise across different segments of the energy sector.
The acquisition of Telos Energy represents the latest step in that strategy. Founded in 2019, Telos specializes in engineering consulting services focused on clean energy deployment, power system planning, and regulatory analysis. The company works closely with clients to evaluate how emerging technologies, market structures, and policy developments will affect future grid operations and investment decisions.
Telos has built a reputation for helping utilities, developers, and policymakers better understand the technical and economic implications of energy transition strategies. Its expertise in integrated resource planning and market forecasting complements PowerGEM’s software and analytics capabilities.
As part of the transaction, Telos co-founders Matthew Richwine and Derek Stenclik will join PowerGEM’s leadership team. Their addition is expected to strengthen the company’s consulting and strategic advisory capabilities while helping integrate Telos’ analytical expertise into PowerGEM’s broader platform.
Richwine said joining PowerGEM provides Telos with a stronger connection to the software tools that are shaping the future of the energy industry. He explained that combining consulting expertise with advanced analytical platforms will create additional value for customers navigating an increasingly complicated power market environment.
Stenclik added that the combination of PowerGEM’s technology platform and Telos’ advisory services will help clients better manage the operational and strategic challenges associated with a rapidly evolving electricity grid.
The financial terms of both the General Atlantic investment and the Telos acquisition were not disclosed.
Several advisory firms supported the transactions. Lazard acted as financial advisor to PowerGEM and TA Associates. Goodwin Procter LLP provided legal counsel to PowerGEM and TA, while Paul, Weiss, Rifkind, Wharton & Garrison LLP served as legal advisor to General Atlantic.
