Our energy production

Modern life requires more energy than ever before. To meet this demand, we use reliable production methods like hydro power and nuclear power. But at the same time, we aim to accelerate the transition to a clean energy future by investing heavily in solar and wind power.

Making progress

Adding biomass to the fuel mix for Combined Heat and Power (CHP) reduces CO₂ emissions.

Meeting demand

Nuclear and hydro power plants give us the stability and flexibility to meet increasing energy demand.

Ready for the future

CO₂-free, renewable energy is the way forward and we’re leading the change for a cleaner world.
