Customers - Drax


We are a leading supplier of renewable energy solutions to industrial and business customers. As the energy market transforms, we are working closely with our customers, offering them services to help them adapt to a world of flexible low-carbon and decentralised energy.

Our customers

We provide a flexible and reliable service to more than 396,000 customer meters, from large industrial and commercial companies to thousands of small and medium-sized enterprises (SMEs).

Haven Power supplies large industrial and commercial customers, as well as SMEs, with renewable and reliable biomass electricity. Opus Energy offers thousands of SME customers low-cost, reliable and renewable energy and buys back renewable electricity from a network of generators and developers across the UK.

Customer service excellence

Our aim is to provide customers with the best possible service. Both Haven Power and Opus Energy have strict standards for treating customers fairly, protecting customer data and privacy and have a clear complaints procedure if things go wrong.

Haven Power was shortlisted for “Supplier of the Year” at the Energy Awards 2018.

Enabling our customers

Smart and digital enablement

Smart meters are key to supporting customers with greater insight and opportunities to optimise their energy use. We are leading the way in rolling out smart meters to UK businesses and are investing in our digital platform to provide commercial opportunities, reduced cost to service and an enhanced customer experience.

In 2018 we upgraded the Haven Power and Opus Energy websites onto a single content management system, making it faster and easier for our teams to react to the market and deliver a smoother customer experience. We also created new functionality, making it simpler for UK businesses to get an accurate quote and switch to us online.

Facilitating prosumers’ route to market

Opus Energy buys energy from generators and developers of solar, anaerobic digestion, hydro and wind power across the UK. In 2018 this amounted to 1,103 GWh of renewable energy generated from 2,176 generators.



During the year, Opus Energy worked in partnership with Home Farm near Daventry in Northamptonshire to trial an innovative solar power and battery storage system. The farm’s 50 kW solar panels generate more power than the farm consumes. The surplus electricity is exported to the National Grid and Home Farm is paid for it by Opus Energy through a power purchase agreement.
