1 Monthly Electrical Energy Overview 218

2 Monthly Electrical Energy Overview 218 Moderate domestic demand and a good level of hydraulic generation enabled France to reach its highest export balance since July 214. French electricity demand fell by 3.4% compared with 217. Corrected for climate factors, the decrease was 1.3%. Hydraulic generation, benefiting from high rainfall in, reached its highest monthly level since 213. Renewable generation (excluding hydraulic) was also up by 8.4%. Wind generation and solar generation increased by 7.4% and 4.8% respectively compared to 217. Electricity consumption in was impacted by several factors, including public holidays, long weekends and temperatures slightly warmer than normal. Market prices were up overall compared to the previous month in Europe. The French monthly price increased a little to 34.42/MWh. The monthly balance for French exchanges remained in favour of exports to all border countries. 8 installations went into service in 218. Monthly Overview

3 Monthly Electrical Energy Overview 218 DEMAND 218 had slightly warmer temperatures than normal (+.2 C). Corrected for climate factors, demand reached 33,274, representing a decrease of 426 compared to 217. GENERATION Generation in was 42,637. Hydraulic generation continued to grow, reaching 7,649, a new high since 213. Renewable generation excluding hydraulic was up by 8.4% to 3,583. Nuclear generation increased slightly by 1.5% compared to 217. This led to a sharp decrease in fossil fuel thermal generation of more than 65%, the lowest level since June 215. WIND AND SOLAR Wind generation was up by 7.4% compared to 217 and reached 1,611. Solar generation, up by 4.8%, reached 1,147. TERRITORIES AND REGIONS Monthly demand of heavy industry customers is down since April, 2.9% in April (compared to April 217) and 3.2% in (comparedto 217), whichcorrespondsto adecreaseof 176for themonthof. Thisdecrease can be explained by the number of holidays and long weekends in. ELECTRICITY MARKETS The French prices remained stable and moderate due to relatively limited consumption and high hydraulic generation. On the other hand, neighbouring countries are experiencing contrasting trends with high prices in Spain and negative prices in Germany and Switzerland. INTERNATIONAL TRADE In, the export balance of trade was 7,852 with 9,347 of exports and 1,495 of imports. This is a record balance since July 214. It reached a maximum value of 15.9 GW on 16. This constituted an export balance across all borders. NEW INSTALLATIONS The works commissioned in 218 aim to secure the power supply to the Châteauneuf-du-Rhône area, strengthen the power supply to the Castellet area, partially renew conductors, to connect an SNCF substation and receive electricity generation from renewable sources.

7 Aperçu Monthly mensuel electrical sur l'énergie energy électrique overview Septembre Distribution of regional generation Distribution of regional consumption Variation in electricity consumption in Electricity demand in 218 was impacted by several factors with public holidays, long weekends and temperatures slightly higher than normal.thedailydemandgraphforthe weekfrom7to 13, dueto publicholidays,has3troughs in demand and 3 peaks in demand. Depending on the region, the energy consumed during this week was between 85 to 94%ofthatconsumedduringtheweekfrom14to 2,alsodueto highertemperaturesduringtheweekfrom7to 13. Monthly demand of heavy industry customers is down since April, 2.9% in April (compared to April 217) and 3.2% in (compared to 217), which corresponds to adecrease of176 for the month of. This decrease can be explained by the number of holidays and long weekends in. Due to the configuration of public holidays and long weekends in April and, the electricity demand from large industry customers has more consumption dips in the curve. The social movements that have taken place since March 22 highlight this phenomenon March Daily demande of heavy industry April 1 mars 3 mars 5 mars 7 mars 9 mars 11 mars 13 mars 15 mars 17 mars 19 mars 21 mars 23 mars 25 mars 27 mars 29 mars 31 mars 2 avril 4 avril 6 avril 8 avril 1 avril 12 avril 14 avril 16 avril 18 avril 2 avril 22 avril 24 avril 26 avril 28 avril 3 avril 2 mai 4 mai 6 mai 8 mai 1 mai 12 mai 14 mai 16 mai 18 mai 2 mai 22 mai 24 mai 26 mai 28 mai 3 mai soutirage 218 : public holiday excluding weekend : Strike day excluding weekends : sunday Monthly Overview

Spread : Price differential between two price areas (here between each price area and France). Price area: Geographic area inside which the electricity price is identical and where exchanges are done with no allocation of capacity.
