MacLean Power Systems announced that it has completed its merger with Power Grid Components, bringing together two manufacturers of engineered equipment used across electrical transmission, distribution, substation, and communications infrastructure.
The combined company will operate under the MacLean Power Systems name and aims to expand its capabilities to support the construction, maintenance, repair, and modernization of critical grid infrastructure.
Funds affiliated with Blackstone Energy Transition Partners and Blackstone’s flagship private equity strategy have become the majority owner of the combined company. As part of the transaction, an affiliate of Centerbridge Partners is making a new investment into the platform. Financial terms of the merger were not disclosed.
The combined business will integrate Power Grid Components’ product portfolio into MacLean Power Systems’ operations. This includes brands such as Allied Bolt, Elliott, ITEC, Meister, Mid-Central, Newell, Royal Switchgear, and Vizimax. The resulting platform is positioned as one of the largest suppliers of highly engineered utility equipment in North America, serving utilities, OEMs, distributors, and other stakeholders across the electrical grid ecosystem.
Alongside the merger, the company announced leadership updates. Steve Scharnhorst will continue as CEO of the combined MacLean Power Systems organization. Mike Plaster, formerly CEO of Power Grid Components, will become president of MacLean Power Systems and oversee commercial and operational activities across the platform.
MacLean Power Systems manufactures engineered products used in the maintenance, repair, upgrade, and construction of electrical transmission, distribution, and substation infrastructure. The company focuses on supplying components and solutions designed to support the reliability and performance of power systems as global energy demand and grid modernization efforts continue to grow.
Power Grid Components has built its business around providing equipment designed to strengthen the resilience and safety of the electrical grid. Through partnerships with utilities and equipment manufacturers, the company has focused on delivering components that help ensure the reliability and capacity of power infrastructure.
Backed by investment from Blackstone and Centerbridge, the newly combined MacLean Power Systems platform intends to scale its capabilities and product offerings as utilities and infrastructure operators continue investing in grid expansion, modernization, and resilience.
