Weg Closes Deal to Buy Indian Sanelec Excitation Systems, Founded in 1998 in Bangalore, with 40 Employees, Revenue of US$ 2.3 Million in 2024 and Ebitda Margin of 29, Strengthening Reivax and the Global Dispute for Power Generation Control, Focusing on Electric Voltage Regulators.
On Thursday, December 11, 2025, Weg announced the purchase of Sanelec Excitation Systems for US$ 5.2 million, in a transaction whose value will be paid after the completion of the deal, subject to usual price adjustments. The Brazilian company informed the Securities and Exchange Commission that the acquisition aims to strengthen Reivax and expand international presence in power generation control solutions.
Founded in 1998 in the city of Bangalore, in the state of Karnataka, Sanelec is today the exclusive partner of Reivax in India and operates in the design and manufacturing of voltage regulators for synchronous generators and electric motors, as well as excitation control systems for power generation. In 2024, the company reported a net operating revenue of US$ 2.3 million and Ebitda margin, a measure of profitability before interest, taxes, depreciation, and amortization, of 29%, indicators that reinforce the potential for integration into Weg’s global portfolio.
Acquisition Strengthens Reivax’s International Presence
According to a statement from Weg, the purchase of Sanelec aims to directly expand Reivax’s presence in the international market, supporting current customer service and creating opportunities for expansion into new generation projects.

Brazilian city gains industrial hub for 85 companies that is equivalent to 55 football fields.
The company sees in the installed base of its Indian partner a way to gain scale in emerging markets and increase share in power generation control solutions outside Brazil.
Reivax, which is already part of the Weg Group, gains with the transaction a production structure positioned in one of India’s main technology hubs.
The strategy is to bring development, manufacturing, and technical support closer to major power generation projects in the region, shortening response times and making offerings more competitive against global rivals.
Who is Sanelec Excitation Systems
Sanelec Excitation Systems was founded in 1998 in Bangalore and specializes in the niche of automatic voltage regulators and excitation systems for synchronous generators and motors.
With approximately 40 employees, the company has built its operation on custom engineering solutions for power generation plants and large industrial installations.
In 2024, the company recorded net operating revenue of US$ 2.3 million, with an Ebitda margin of 29%.
These numbers indicate a lean business focused on technology and capable of generating cash, facilitating integration into Weg’s management model.
For the Brazilian group, incorporating a profitable player in a key market reduces risks and accelerates the capture of commercial and operational synergies.
Focus on Power Generation Control Solutions
In the market announcement, Weg emphasizes that the acquisition plays a central role in the growth strategy for power generation control solutions, a segment in which the company has been increasing investments in recent years.
Sanelec brings to the group not only the product portfolio but also relationships with local customers and regulatory knowledge of India.
With the operation, Weg now has a greater capacity to offer voltage regulators and excitation systems integrated with Reivax’s solutions, enabling more comprehensive projects in hydroelectric, thermal plants, and other generation sources.
The combination of Brazilian engineering and production presence in Bangalore is likely to strengthen Weg’s competitiveness in international bids and contracts.
Transaction Conditions and Next Steps
Weg reported that the amount of US$ 5.2 million will be paid after the completion of the transaction, subject to the fulfillment of usual precedent conditions for this type of operation.
Among these requirements are regulatory and contractual steps that must be fulfilled before the definitive transfer of control of Sanelec to the Brazilian group.
Meanwhile, the company reinforces that it will continue to support the current portfolio of Reivax and Sanelec clients, seeking to maintain service continuity and customer trust.
And you, do you believe Weg is making the right move by betting on India to strengthen Reivax and grow in power generation control solutions abroad?
