The Imtech Group


Our Parent Companies

EDF is helping Britain achieve Net Zero by leading the transition to a cleaner, low emission electric future and tackling climate change. EDF is Britain’s biggest generator of zero carbon electricity, meeting around one-fifth of the country’s demand and supplying millions of customers with electricity and gas.

EDF generates low carbon electricity from eight nuclear power stations, more than 30 onshore wind farms and two offshore wind farms and operates one of Britain’s biggest battery storage units, one gas and one coal power station, thousands of EV charge-points and combined heat and power plants. Wind, nuclear and solar all produce electricity that is zero carbon at the point of generation and have similar emissions over the build, run and retire lifecycles.

EDF is the world’s biggest electricity generator. In the UK it employs around 13,000 people.

Dalkia Group, a subsidiary of the EDF Group, is one of the leading providers of energy services in France. Dalkia offers its clients tailor-made solutions scaled to fit each building, city, municipality, region and industrial site.

Dalkia rises to the challenge of the energy transition and provides its clients with expertise covering the entire energy chain, from energy supply to optimisation of their energy consumption, as well as operation and maintenance of installations.

All Dalkia’s solutions are paired with energy efficiency commitments and long-term performance guarantees.
