At our 2,000-acre site at Wilton International on Teesside, we supply electricity via the UK’s largest private wire network and specialist services to energy-intensive industrial businesses.

We own the majority of available development land at Wilton International and offer pre-consented industrial development plots with ready-to-use power, utilities and infrastructure. This helps our customers reduce investment project costs, risk, and timeframes.

We are committed to reducing emissions associated with the power we supply to our customers. We do this by adopting low-carbon solutions and actively attracting those working in fields supporting sustainable supply chains, including battery energy storage systems, hydrogen and sustainable aviation fuel areas.


Teesside, home to Wilton International, is a prime location for future decarbonised power, encouraging investment and supporting regional growth.
