NEW YORK--(BUSINESS WIRE)--Dec 10, 2025--

MacLean Power Systems (“MPS”) and Power Grid Components (“PGC”), two leading manufacturers of engineered components and solutions for electrical transmission, distribution, substation and communication infrastructure, announced today the signing of definitive agreements to merge and recapitalize MPS. Pursuant to the transaction, PGC’s existing financial sponsor, funds affiliated with Blackstone Energy Transition Partners and Blackstone’s flagship private equity strategy (“Blackstone”), will become the majority owner of the combined company, acquiring ownership interests in MPS currently held by Centerbridge Partners (“Centerbridge”). The combined MPS / PGC will create a unique platform serving U.S. utilities in an era of unprecedented demand due to growing power consumption, electrification, aging infrastructure, grid hardening trends, and an evolving power supply.

Founded in 1986, MacLean Power Systems is a leading provider of customer-driven, highly engineered solutions for the construction, maintenance, repair, and upgrade of critical electrical transmission and distribution and communications infrastructure. MPS offers a comprehensive portfolio of industry-leading products―switches, pole line hardware, insulators, arresters, connectors, anchors, crossarms, and related components―delivered with superior lead times. From emergency restoration to full-scale electrical grid buildouts, MPS is a trusted partner for utility and telecom operators. MPS delivers innovative, easy-to-install products that help reduce grid operating costs and drive long-term reliability.

PGC was formed in 2017 to grow leading businesses that supply products used in the North American electrical power grid and adjacent industries. PGC’s current portfolio includes high-voltage disconnect switchgear (Royal); high-quality porcelain, composite, and glass insulators (Newell and Meister); instrument transformers (ITEC); outside plant hardware (Allied Bolt); controlled switching devices (Vizimax); pad-mounted power distribution products (Elliott); and fixed-load transformers (Mid-Central Electric). PGC’s customers include many of the nation’s largest utilities, original equipment manufacturers, telecommunications companies, packagers, and distributors.

The combined MPS / PGC will be one of the largest suppliers of highly-engineered utility equipment in North America, offering customers a comprehensive portfolio of critical solutions for transmission, distribution, substation, and communication infrastructure. Management at both MPS and PGC are planning to remain in place post-closing to drive the next phase of growth together.

Steve Scharnhorst, CEO of MacLean Power Systems, said: “I’d like to thank Centerbridge for their partnership and our customers and employees who have helped us grow over the last three years. We are excited to partner with PGC and Blackstone to accelerate the growth of this industry-leading platform.”

Mike Plaster, CEO of PGC, said: “MacLean Power Systems is a premier brand in our industry, built on decades of providing reliable, high-quality, essential components for the power grid and adjacent industries. MPS’s comprehensive product portfolio is highly complementary to PGC’s solutions offerings, and MPS’s customer service-driven culture and values are consistent with those of PGC. Together, we will be able to serve our customers better in all segments of the electrical grid.”

JP Munfa, Senior Managing Director, and Mark Zhu, Managing Director, at Blackstone said: “MacLean Power Systems plays a vital role in supporting the safety, efficiency, and resiliency of the grid. We are excited to partner with a business and management team of this caliber at such an exciting time for the sector. Together with PGC, we look forward to accelerating MPS’s continued growth as an innovative and trusted platform supporting rapidly growing global electrical infrastructure needs.”

David Foley, Global Head of Blackstone Energy Transition Partners, added: “As a leading energy investor focused on investment opportunities benefiting from increasing electrification and the energy transition, we proactively seek out companies with strong management and work with them to fully capitalize on growth opportunities. MacLean Power Systems is one of the leaders in the industry, which together with PGC is well positioned to benefit from growing need for critical equipment that improves the safety, reliability, and efficiency of America’s electrical network.”

Conor Tochilin, Senior Managing Director at Centerbridge, said: “Our investment in MacLean Power Systems highlights our longstanding thematic focus on electric grid modernization and approach to value creation in partnership with great management. We congratulate Steve and the entire MPS team for delivering exceptional growth over the last three years, and we are excited for the combination of MPS and PGC, which will unlock potential for both companies in a sector with strong secular tailwinds.”
