Blackstone Takes Majority Control of Newly Merged MacLean-PGC Utility Infrastructure Platform

Founded in 1986, MacLean Power Systems has a long-standing reputation for delivering high-quality, reliable components to the power grid and adjacent industries. Power Grid Components, established in 2017, complements this with specialist businesses focused on high-voltage switchgear, insulators, transformers, controlled switching devices, and distribution products. Together, MacLean-PGC will provide a sector-leading range of products that address the growing demands of grid resilience and electrification.

Market Context and Investment Themes

Blackstone’s investment aligns with its high-conviction themes around electrification, rising power demand, and the imperative for long-term grid resilience. David Foley, Global Head of Blackstone Energy Transition Partners, emphasized that the merged platform is well-positioned to capitalize on the increasing need for critical equipment that enhances the safety, reliability, and efficiency of America’s electrical network.

This acquisition underscores Blackstone’s broader strategy to expand its footprint in energy transition infrastructure, following recent investments in power equipment, grid services, and energy technology sectors. The deal reflects private equity’s growing role in modernizing the U.S. electric grid, a sector experiencing accelerated investment due to regulatory support and the push for decarbonization.

Leadership and Cultural Synergies

PGC CEO Mike Plaster highlighted the cultural and operational synergies between the two companies, noting their shared customer-focused approach and complementary product lines. This cultural alignment is expected to facilitate integration and drive innovation within the combined platform, enhancing service delivery to utility customers nationwide.
