The energy transition: an industrial and societal challenge
Integrate renewable energy and new uses of electricity in the most efficient way, are Enedis everyday challenges.
Enedis deals with technical issues of:
- Intermittent and unpredictable production
- Variable power demand, geographically spread linked to the recharging of electric vehicle.
Injecting electricity directly into the distribution grid at multiple points tends to disrupt voltage levels, which in turn can place the electrical equipment of customers at risk. Facing these new constraints, Enedis is experimenting solutions that contribute permanently to the local balance between supply and demand of electricity, with the will to maintain the best quality of supply.
95% of renewable energy sources are connected to the distribution grid managed by Enedis
Today there are a vast number of producers of renewable energy, solar in particular: while there were practically none in 2005, more than 350,000 solar power producers are now connected to the local low-voltage grid.
Objectives of the European Union:
20% of renewable energy in the EU’s energy consumption by 2020 (meaning 23% for France: 33% in heat-producing, 27% in electricity and 10,5% in transports).
Objectives of the French energy transition law for the green growth:
- Reducing by 50% the energy consumption from 2012 until 2050
- Reducing by 50% the nuclear share in the energy mix by 2025
- Reducing by 30% the consumption of fossil fuel from 2012 until 2030
- Reaching 23% of renewable energy in the energy consumption by 2020 and 32% by 2030
- Reducing by 40% the greenhouse gas emission from 1990 until 2030.
A new paradigm for the grid
Today’s grid was initially designed to transmit electricity in just one direction, from power stations to consumers.
A smart grid must allow electricity to flow in both directions to cater for the electricity produced using renewable energy sources.
Smart grids must also allow the development of new electrical applications, including electric vehicles.
