THE SMART GRID USES TEHNOLOGIES OF OWER ELETRIITY, INFORMATION AND TELEOMMUNIATION TO OTIMISE GENERATION, DISTRIBUTION AND ONSUMTION. Its objective is to optimise all the connections of the electricity network, from the producers to the consumers, in order to improve the energy efficiency of the system. / /

3 Enedis, European leader of Distribution Systems Operator Enedis, as the new name of ERDF since June 06, manages 95% of distribution network in continental France. Enedis was created on January st 008, in the wake of the liberalisation of the energy sector. Enedis is a state company with around,000 sites located across France. As part of its remit, the company frequently performs work on the grid, including the set-up of connections, commissioning, repairs and supplier switching, 4 hours a day. Enedis is independent from the electricity suppliers which are in charge of selling and managing the power supply contract. Its 9,000 employees control, maintain and develop some. million kilometers of power lines, serving 5 million customers. This makes Enedis the European leading electricity distributor. The grid is owned by the local authorities (municipalities or joint municipalities), which award concessions to the company and entrust it with the grid s management through delegation of public service. million interventions are made every year. More than billion are invested each year by Enedis throughout France. As the organisation in charge of managing the public distribution network, Enedis is responsible for ensuring that access to the power grid meets the expectations of stakeholders. Now that the market is open to competition the service continuity of the country s electricity distribution network lies at the heart of a system that requires Enedis to liaise with the government, the Energy Regulation ommission, local councils, the authorities that grant concessions and the grid users (customers, suppliers and producers). The medium-voltage grid already «smart» Each day, Enedis develops, maintains and controls more than. million kilometers of power lines, including km of LV (low-voltage) and km of MV (medium-voltage) lines, serving 5 million customers. Sensors and remotely controlled devices have already improved the reliability of power grids over the last twenty years. At the end of the 980s, French customers suffered an average of 400 minutes of power cuts per year. In 05, this figure dropped to 6 minutes (average power outage per year per customer, irrespective of the cause). This highlights Enedis successful investments to equip medium-voltage grid with sensors and numeric devices in order to strengthen its inner connections. THE MEDIUM-VOLTAGE (MV) GRID VIEW REMOTE ATION Today, when an incident occurs on the medium-voltage grid, automated software (DEMS/OMS) are able to restore power in few minutes to 70% of the customers affected, without human intervention. These advanced management processes, known as self-healing functions, allow electricity to be restored automatically and remotely. These terms vividly describe the new qualities of power grids that are able to reconfigure themselves in record time, sometimes without customers even noticing it, with the aim of maintaining the quality of electricity distribution. THE LOW-VOLTAGE (LV) GRID UBLI SERVIE ROLES Operate and modernise the grid onnect customers to the grid Support the projects of local councils Manage and control the grid remotely 4/7 REAL-TIME MONITORING OF THE MEDIUM-VOLTAGE GRID Regional ontrol entres Enedis «control towers» 500 specialists one could call them the air-traffic controllers of the electricity world are posted in the 0 Regional ontrol entres. Effectively, these are Enedis s control towers, i.e., the entities responsible for managing the power grids. Enedis has modernised around 600,000 km of power lines, which are now equipped with more than 05,000 remote-control systems supervised and operated by these 0 centres. The role of the latter is to monitor the state of the medium-voltage network in real-time, 4/7, and to resolve incidents in just a few minutes. These functions allow incidents to be located automatically and therefore very quickly, before isolating the faulty section of the network and reconfiguring the grid so as to minimise power outages for customers.,5 source substations in France 05,000 remote-control systems on the Enedis network Over the last 0 years, Enedis has automated the medium-voltage grids extensively. The automation of these grids helped restore power to 9% of customers less than day after Atlantic Storm Quentin, whereas it took 0 days to achieve the same result in distribution substations rovide electricity metering services to energy suppliers erform repairs 4/7 whatever the weather The challenge Enedis is now keen to take is to upgrade the low-voltage (LV) grid so as to cater for the advent of solar power and electric vehicle. Enedis continually ensures the grid balance and the power supply quality. 4/ 5/

4 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 005, more than 40,000 solar power producers are now connected to the local low-voltage grid. Objectives of the European Union: 0% of renewable energy in the EU s energy consumption by 00 (meaning % for France: % in heat-producing, 7% in electricity and 0,5% in transports). Objectives of the French energy transition law for the green growth: Reducing by 50% the energy consumption from 0 until 050 Reducing by 50% the nuclear share in the energy mix by 05 Reducing by 0% the consumption of fossil fuel from 0 until 00 Reaching % of renewable energy in the energy consumption by 00 and % by 00 Reducing by 40% the greenhouse gas emission from 990 until 00. ower stations Smart grids must also allow the development of new electrical applications, including electric vehicles. In the wake of the energy transition, the volume of power and number of generation sites of intermittent renewable energy will keep up growing intensely. Furthermore, new uses of electricity such as the electric vehicle will involve an upgrade of the distribution network to incorporate recharging stations.

To prepare and support this major technical shift, Enedis is investing in numerous demonstrators in France and Europe. Their aim is to design tomorrow s «smart grids», solutions combining electricity and NIT. The Linky smart metering system is a core element of this new system. The integration of new technologies will allow these grids to feedback information. It will make it possible to analyse the actions of the electrical system s various stakeholders so as to guarantee the efficiency, reliability and security of electricity distribution. With all these technologies that come with Smart Grids, it is possible to manage the network balance in real time, by adapting consumption to production. The adjustment in the future will shift towards the demand side, making the consumer an active player. Enedis is contributing to the development and the smooth running of the whole system. Smart Grids development relies on real condition experiments (equipment, software tools, telecommunications ) Smart Grids are the combination of advanced power network solutions and information and telecommunication technologies. The following solutions are currently tested by Enedis on its pilot projects (see next page demonstrators map): Implementation of smart meters / sensors that give precise information about the network state and consumption profiles. Implementation of data exchange system with decentralised generation sites. Development of tools to forecast local consumption and production, and tools to simulate possible constraints on the local scale (8 days to one hour ahead power-flow forecasts). Implementation of advanced digitised equipment in primary substation (transformation system from TSO to DSO, HV to MV) and secondary substation (transformation system from MV to LV): digitised controls, voltage regulation Development of advanced software (incidents location, self-healing, voltage control ). Solutions for active downstream meter management (demand and storage management). 6/ 7/

InterFlex project brings together 5 European distribution system operators to improve the performance and the reliability of a local electric system by testing new uses of local flexibilities and new solutions of system automation. 8/ age 9

6 Linky, not only a smart meter but also a communication infrastructure arry on with distribution network modernisation on the low-voltage grid Thanks to the Linky smart meter roll-out, Enedis is modernising the low-voltage electricity network making grid monitoring and data processing easier and more efficient. Linky is the first step on the path to smart electricity grids. It is replacing the former meter in residential and professional blocks (with a contract power <6kVA). Its installation contributes to making the network smart by creating a constant interaction between monitoring centres and the grid. Towards the digitissed electricity network The experiments of new technologies led by Enedis should be used to identify the best solutions in terms of choice and roll-out for the local authority. Even if most experiments will draw their conclusion in 06 or 07 only, Enedis is already on its way to prepare actively the roll-out of industrialised solutions. From the maturity and value analysis, for the grid and the community, of the different «smart» solutions currently tested, Enedis has written its technical roadmap to implement smart solution by 08. Linky makes it possible to: Know better the network condition; Detect incidents and reduce in this way the intervention delays (power supply quality); Make the incorporation of renewable energy sources and electric vehicle easier on the network; rovide precise consumption data to the consumers. And offers new services to consumers: Remote intervention and reduced delays (4 hours instead of 5 days); Easier access to consumption data to control it better; Bills based on actual consumption and not on estimates; Diversified range of pricing offers. As its mission of DSO, Enedis manages a fleet of 5 million meters (power < 6 kva). These meters are part of the concession s contract and belong to the local authorities. Every year, Enedis installs new meters and replaces old meters, which means million new meters a year. The industrialisation of smart solutions by 08 will be decided on a technical platform tested and validated by Enedis teams. This base will be used to develop new customers or local authority offers. The Enedis roadmap is structured around the three main field of technical activities: the remote monitoring of the grid; the management and the maintenance of the grid; Enedis has prepared a roll-out plan to allow all the consumers on the territory to have the new Linky smart meter. Linky s industrialization started on December, st 05 A roll-out plan based on three criteria: rovide Linky s feature as soon as possible to the greatest number of consumers. Support the territories development projects in a collaborative way. Observe an economic and technical optimum. How is the roll-out plan developed? In order to guarantee the economic and operational performances of the project, but also to provide visibility to the corporate partners of Enedis. In a progressive and fair manner, in all the regions. With the assurance to start the roll-out in all the departments within years, to secure the deadlines and to handle the costs. By working with the local employment market. A roll-out on the whole territory: For Enedis, national public service operator, the challenge of the deployment is to progress as quickly as possible on the whole territory. Enedis will rely on its territorial grid to offer a strong support to local stakeholders. Since the end of 05, a support process will be established for the customers: ersonal letters for customers, posters in Town Hall, phone support, web site. Stakeholders (elected members, associations, lessor ) will be associated to this process creation and will sustain it. the development, connection, database and mapping. Examples of mature solutions for the distribution network for 08: Smart rimary substation: transformation system from HV to MV, equipped with numerous advanced sensors (digitised remote control) and communication tools interacting with other parts of the network (regional control centres, smart MV/LV substation, sensors, etc) Smart MV/LV substation: transformation system from MV to LV equipped with sensors (electronic and environmental measures) and communication tools towards control centres The Linky smart meters roll-out will be initiated: - in all administrative regions in 06; - in all regional metropolis before the end of 07; 5 million smart meters will be deployed during 6 years and will replace French people meters Million de meters 4 millions DISTRIBUTION 5 M Medium-voltage (MV) producer equipped with smart objects: located in the connection to the grid, solutions delivering grid state information and level of production information towards control centres and that allow remote intervention ommunicating tools that measure in real-time the state of the network (voltage, current, etc). - in all departments before the end of 08. // Roll-out by semesters NB: in Bretagne and ôte d Azur that have the characteristic of electricity peninsula, the roll-out will be carried out in 5 years. 0/ /
