PCS is headquartered in Rothschild, Wisconsin, and specializes in controllers and excitation systems for power plants. A key focus is the North American hydropower industry. According to the company, the division’s installed base comprises more than 1,200 hydropower generators. Its customers include major energy utilities in the U.S. and Canada. In fiscal year 2025, PCS generated net operating revenue of $9.6 million.

With this acquisition, WEG aims to strengthen its position in the North American power generation market while expanding the activities of REIVAX North America. The company is part of the WEG Group and specializes in excitation systems and controllers for power generation.

The strategic focus is on complementing existing technologies. While REIVAX contributes its expertise in excitation systems, PCS offers open-architecture controllers. By combining both portfolios, WEG aims to create a broader offering for the modernization of hydroelectric power plants. This will provide customers with more comprehensive solutions for the control and regulation of their plants.

Manfred Peter Johann, Vice President of Automation & Systems at WEG, views the acquisition as part of the Group’s sustainable growth strategy. The combination of REIVAX and PCS technologies is intended to expand the range of solutions and strengthen competitiveness in the North American market.

The transaction thus complements WEG’s existing business with established control technology and an extensive installed base in the hydropower sector. At the same time, the Group is expanding its presence in modernization projects in the U.S. and Canada.
