Get involved with FES 2021

While FES is an ESO publication, our analysis considers the whole energy system. This makes sure we’re taking into account the implications for, and interactions across, electricity, gas, heat and transport. Our scenarios reflect the year-round feedback we receive from all of our stakeholders across the energy landscape and beyond. Please continue to share your views with us.
