Nuclear New Build which is tasked with the delivery of the new generation of nuclear plants in line with EDF’s global programme of producing safe, affordable, reliable, low-carbon production of electricity in the UK.

Energy Sourcing and Customer Supply runs power stations and wind farms, buys and sells power to meet future generation and customer needs and deals with all our energy customers.

Our history

EDF Energy as we know it today was born in 2003

But our history actually began during the years leading up to 2002, when three energy companies ─ SEEBoard, London Energy and SWEB ─ were brought together.

Since then, we've grown steadily, integrating and streamlining our operations to become more responsive and effective in a fast-changing marketplace.

The combination of EDF Energy and British Energy in 2009 forms one of the UK’s largest energy companies. The combined business is the UK’s largest producer of electricity.

We’re now involved in some of the UK’s most important projects and developments. Growing to become one of the country’s largest energy companies in such a short time is an impressive achievement.
