Monthly Electrical Energy

Overview

May 2018

Moderate domestic demand and a good level of hydraulic generation enabled

France to reach its highest export balance since July 2014.

French electricity demand fell by 3% compared with May 2017. Corrected for

climate factors, the decrease was 1%.

Hydraulic generation, benefiting from high rainfall in May, reached its

highest monthly level since 2013. 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 May 2017.

The monthly balance for French exchanges remained in favour of exports to

all border countries.

8 installations went into service in May 2018.

2Monthly Overview - May 2018

Monthly Electrical Energy Overview

May 2018

Electricity consumption in May 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.

GENERATIONGeneration in May was 42,637 GWh. Hydraulic generation continued to grow, reaching 7,649 GWh, a new high since 2013.

Renewable generation excluding hydraulic was up by 8.4% to 3,583 GWh. Nuclear generation increased slightly by 1.5%

compared to 2017. This led to a sharp decrease in fossil fuel thermal generation of more than 65%, the lowest level since

June 2015.

WIND AND SOLARWind generation was up by 7.4% compared to May 2017 and reached 1,611 GWh. Solar generation, up by 4.8%, reached

1,147 GWh.

INTERNATIONAL TRADEIn May, the export balance of trade was 7, 852 GWh with 9,347 GWh of exports and 1,495 GWh of imports. This is a

record balance since July 2014. It reached a maximum value of 15.9 GW on 16 May. This constituted an export balance

across all borders.


Monthly Electrical Energy Overview

May 2018

NEW INSTALLATIONSThe works commissioned in May 2018 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.

DEMANDMay 2018 had slightly warmer temperatures than normal (+0.2 °C). Corrected for climate factors, demand reached 33,274

GWh, representing a decrease of 350 GWh compared to 2017.

TERRITORIES AND REGIONSMonthly demand of heavy industry customers is down since April, 2.9% in April (compared to April 2017) and 3.2% in

May (compared to May 2017), which corresponds to a decrease of 176 GWh for the month of May. This decrease can be

explained by the number of holidays and long weekends in May.

ELECTRICITY MARKETSThe 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.

Electricity demand in May 2018 was impacted by several factors with public holidays, long weekends and temperatures

slightly higher than normal. The daily demand graph for the week from 7 to 13 May, due to public holidays, has 3 troughs

in demand and 3 peaks in demand. Depending on the region, the energy consumed during this week was between 85 to

94% of that consumed during the week from 14 to 20 May, also due to higher temperatures during the week from 7 to 13

May.

Daily demande of heavy industry

soutirage 2018 : public holiday excluding weekend : Strike day excluding weekends: sunday

April MayMarchGWh

Monthly demand of heavy industry customers is down since April, 2.9% in April (compared to April 2017) and 3.2% in

May (compared to May 2017), which corresponds to a decrease of 176 GWh for the month of May. This decrease can be

explained by the number of holidays and long weekends in May. Due to the configuration of public holidays and long

weekends in April and May, 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.

Negative prices were observed in several European

countries (Germany, Switzerland, France, Belgium,

Slovenia) on public holidays and weekends where

renewable production was significant (wind and

solar in Germany, hydraulic in Switzerland).

There were a lot of them in Germany, but also in

Switzerland, where 22 negative hourly prices were

recorded during the month. In this country, the

price reached a historical minimum daily average of

€5.8/MWh on 1 May.

Glossary

Prices in EuropeMonthly average of spot prices in the different price zones of the coupled area. France is always represented in white, the other areas are coloured based on the difference in

price compared with France (blue: lower price, red: higher price, the deeper the colour, the greater the difference).

Daily spot price changes

Change of the spot price in France and in the coupled neighbouring

regions, over a month in daily average, (NB: for Italy the price of

the northern area is shown, for Nordic countries the average of the

areas displayed on the map is shown).

Spot price: Wholesale price of electricity, determined by the power exchanges the day

before for delivery the following day, for each hour of the day.

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. A price area may combine several

countries (for example: Germany, Austria, Luxembourg) and a country may be subdivided

into more than one price area (for example: Italy, Norway).

Daily extrema :

Extrema of the half hour mean power value of the global international

commercial exchanges, observed daily.

Nature of work

Why can the data displayed in real time be different from that published in the Monthly Overview ?The data published by RTE changes several times before becoming “final”. It is, in fact, refined according to the information that RTE receives at several moments:

1- At the time of real-time publication, the data is taken from telemetry carried out continuously by RTE. It is this data that can be viewed in éCO2mix and communicated during peak demand.

2- In the following month, this data is “consolidated”, i.e. refined using metering data from the various electricity distribution networks. This consolidated data is published in the Monthly

Overview and updated in éCO2mix.

3- During the first half of the following year, it becomes “final” by being refined with the latest metering data from the distribution networks.
