Wilson Power Solutions India Factory inauguration

Wilson Power Solutions Group, a multi-award-winning power and distribution transformer manufacturer, celebrated the grand opening and inauguration of a new state-of-the-art transformer manufacturing facility in Chennai, India, marking a significant milestone in the company’s growth and its 80th anniversary year. The new £23 million investment increases the company’s production capacity and strengthens its position as a crucial supply chain partner for electrical infrastructure projects in India, the UK and international markets.

The project was delivered in a record timeframe; it took under 14 months between laying the foundations and starting the trial run. The 14-acre site enables a sixfold increase in manufacturing capacity, resulting in an annual production capacity of up to 20,000MVA. Employing over 650, the new facility comprises:

Three fully equipped, climate-controlled manufacturing bays
Dedicated ISO Class 8 cleanroom winding bay
Office building with a central atrium to reduce air conditioning load

Employee Building with an on-site hospital, crèche room, 150-cover canteen, recreational space and training centre
Ancillary buildings such as a fire pump room, energy centre, security building, chillers and oil storage facilities

The site will be powered by solar PV with 1.8MW to be installed in Phase 1. The architectural design prioritises energy efficiency and provides a modern working environment and utmost comfort to the staff.

Grand Opening on 28 October 2026

Selvi Keerthana Sampath, Minister for Industries, Investment Promotion and Commerce, Government of Tamil Nadu, was the chief guest at the inauguration, accompanied by other guests of honour:

S. Vijayakumar, Member of the Legislative Assembly (MLA), Gummidipoondi
Ms. Mia Lupoli, First Secretary, Trade, Energy and Infrastructure, British High Commission
Ms. Pallavi Verma IAS, Executive Director, Guidance Tamil Nadu

The opening celebration brought together over 250 guests, including customers who develop renewable energy and battery energy storage projects across India, the UK and Europe. Wilson Power Solutions was delighted to welcome some of our longstanding customers from the UK who have been with us on this growth journey for decades. Material suppliers and plant suppliers who supported the factory design, build, and fit-out, and other strategic partners such as bankers and auditors, marked this special occasion with Wilson Power Solutions.

The grand opening began with the lamp lighting, a traditional Indian ceremony performed at auspicious occasions to move from darkness to light. Then honourable guests and the Wilson leadership team delivered speeches on the significance of this manufacturing plant to the supply chain of electrification and decarbonisation projects. The chief guest and other guests of honour proceeded to a ribbon-cutting. This was followed by a site tour where our guests had the chance to visit the multiple production facilities and supporting buildings. In the evening, Wilson celebrated its 80^th anniversary with customers and staff at ITC Grand Chola.

In her welcome speech, Erika Wilson, Managing Director, described the company's challenging but rewarding journey over the past 80 years. The story began with Erika’s grandfather, Richard Wilson, who set up a small workshop in Leeds, UK, in 1946, and whose determination and business mind led to expansion and to leaving the company to his sons, Colin and Dennis, who started selling refurbished distribution transformers. Pursuing their own transformer supply took them eventually to India. To have better control of the quality, the business decided to build its own manufacturing plant in India. One of the Leeds employees, Srinivasan Sudharsanam, moved back to India to build and lead the project back in 2006. To meet the growing demand for transformers, the Wilson Group decided to build a second factory in India and invest in new production facilities in the UK. Erika spoke about the importance of employing young engineers with an average of 28 years old and 15% female staff, further supported by an annual graduate program.

The chief guest, Selvi Keerthana, delivered a speech on the importance of investments in Chennai industries to employ the local workforce and improve the economy. Srinivasan’s story touched the minister, who thought he was a role model for all Indians who should go back and build their country. The speech was followed up by Mia Lupoli from the British High Commission, who talked about the support provided by the commission.

A follow-up presentation from Hari Malepati, the Group Technical Director, illustrated India's investment and growth, describing the features of the new factory, Unit 2.

The 14-acre facility is a major investment of £23M in Wilson Power Solutions India’s manufacturing capabilities, providing the infrastructure to support growing demand for reliable, efficient power distribution equipment. Designed to manufacture transformers rated up to 80MVA and 132kV, the site will enable the business to serve increasingly complex power infrastructure requirements across India and international markets. Wilson Power Solutions India is committed to a further 300 crore investment to further increase its product offering and manufacturing capacities.

As part of the expansion, Wilson Power Solutions has repurposed its existing 5,000-square-metre Chennai site (Unit 1) into a dedicated transformer tank fabrication factory. The vertically integrated factory will enable the company to design and manufacture more tanks in-house, strengthening quality control, increasing customisation options and securing its supply chain.

80^th Anniversary Celebration in India

Following a series of celebration events in the UK, Wilson Power Solutions celebrated its 80^th anniversary at ITC Grand Chola with customers and employees from both the UK and India. The guests enjoyed The Colours of India dance featuring dancers and artists from across India. British and Indians were brought together over their love for cricket with a quiz that found everyone in the room engaged. The evening concluded with great Indian music that made everyone dance.
