388 TWh delivered
new connections
11 million technical interventions
61 minutes SAIDI
9,3 GW of wind capacity connected
5,4 GW PV capacity connected
employees
€ 3,2 billion investments

3. Electricity distribution is at the heart of the main challenges impacting the electricity sector
Energy transition and new regulations
Application of energy policy on a local scale
Innovative context including many new digital technologies
Electricity consumption stagnation at national level with great discrepancy on local scale
French residential electricity bill
Renewable and social taxes
Enedis operates in a regulated context, which implies financing our assignments with a very competitive tariff
Network
Taxes
Generation and Supply

4. Linky : a major industrial project
Smart meters are key to achieve the goals of energy transition
They enable consumers to become pro’sumers
Better knowledge of energy consumption and energy savings
Development of demand-response
Development of self-consumption
They constitute the first brick towards generalized smart grids
35 million smart meters will be deployed between 2015 and 2021 for an estimated investment of 5 bn€

5. The Data revolution Thanks to smart meters, DSOs become data operators
They will provide data to :
Empower consumers
Help suppliers, businesses, start-ups, etc. develop new services
Help local authorities become fully actors of their local energy policy
DSOs will play a key role in demand side management schemes
Enedis has developed a digital agenda with several dimensions
Digitalization of clients interfaces
A big data initiative for a better performance such as predictive maintenance
An open data website
250 billions data per year
Thanks to smart meters, the number of consumption data will expand 4000-fold from current levels

6. The new roles of local authorities in France
Energy transition consolidates the role of local authorities to develop :
Renewable resources facilities
Energy savings programs
Low carbon mobility programs
Smart grids & micro-grids experiments
DSOs are natural partners of local authorities
Cities own the distribution network operated by DSOs
DSOs provide data to help local authorities develop their energy policies
DSOs are in charge of connecting RES and charging infrastructures

7. Distribution networks connect 95 % of RES
The French Energy Transition Law set a target of 23% renewable energy by 2020
In France, 95 % of renewable energy sources are connected to the distribution networks : they become collection networks.
15 GW of RES over 10 years, i.e. almost 10 nuclear reactors
It implies :
Significant investment to reinforce the grid
New technological innovations
Better coordination with all the players
“In a rapidly changing energy landscape, electricity grids will play a key role”
EU Commissioner Maros Sefcovic

8. The emergence of smart grids
Enedis is contributing to the emergence of smart grids with 20 pilot projects in France and Europe Smart grids will enable better integration of RES thanks to local flexibilities Electric vehicles could be essential for the future of smart grids…

9. Several residential blocks
Electric vehicles roll-out is a key challenge for distribution networks
Charging points
(March 2016)
Over charging points are connected to the French distribution network, for a total power of 557 MVA
The French Energy Transition Law has set a target of 7 million charging points by 2030
Charging method and location will have a strong impact on the infrastructure cost

By 2030, the associated impact with regards to energy will be limited…
… However, it will be significant in terms of power
Charging power, location and management schemes are crucial challenges for the distribution network

10. Enedis acts as an enabler to speed up public charging point roll-out
In France, four major companies have gained national operators status
27 stations
200 stations
8 000 stations
40 stations
Enedis has optimized its new connection process
Enedis is developing new tools to minimize connection and grid reinforcement costs
Illustration of the « ORME » tool used in Chambéry, France
Estimation of the level of constraint
New secondary substation needed
Adaptation of a secondary substation needed
Reinforcement of low voltage (LV) network
Creation of a dedicated LV line
Connection to an existing LV line more than 36 meters away (customized connection with an extension)
Connection to an existing LV way less than 36 meters away (i.e. standard connection)

11. Enedis has set ambitious goal to electrify its fleet and currently tests active load management
With over electric vehicles, Enedis’ fleet ranks 2nd in France
Enedis is currently testing load management schemes on a large scale, with 40 vehicle involved

Enedis also plans to assess vehicle-to-grid technologies as well as distributed energy resources & electric vehicle charging synchronization, with new innovative projects

12. Map out European corridors for innovative mobility
In order to foster electric vehicles use, well thought deployment of charging points is key :
To reassure drivers regarding their mileage range
Because of the impact of public charging infrastructure on the grid
Creation of European corridors for innovative mobility would give a strong signal and would allow for better grid planning.
Among the existing initiatives is the joint declaration between France, Spain and Portugal on November 23rd 2015 to deploy charging stations on their respective highways systems.
