Roles and liabilities

Producers

• required to dispatch their units in order to provide the energy volume sold to their counterparts

• required to provide margins to handle the outages on their units

• required to offer on the BM the total of the remaining power technically available on each unit (French law)

Suppliers

• required to satisfy the contracts of electricity delivery with their customers

• required to be covered against the risk on the level of consumption of their customers

TSO

• required to provide a non discriminatory network access to all users

• operational responsibility to maintain load-generation balance and system security by calling for the reserves submitted by the market participants on the BM, according to their merit order

• Balancing electricity generation with consumption at all times

(Electricity cannot be stored!)

• Guaranteeing the secure operation of the power system (carrying

electricity 24 hours a day, 7 days a week)

• Maintaining and developing the network to allow generators, distribution

networks and consumers to be connected, as well as interconnection

with neighbouring countries

• Guaranteeing non-discriminatory access to the transmission network,

whilst ensuring that commercially sensitive information remains

confidential

• Integrating transmission installations into the environment and ensuring

the security of people and property

… all at the most economical cost possible

Different time scales for forecasting

Long-term : investment Mid-term : few months to few years maintenance program Short-term : few days to day-ahead prepare dispatch program Intraday and real-time : market + balancing mechanism

Weather influence on the balance

Electricity demand France : ~2400MW/Celsius Degree in winter Consumption for cooling in summer is increasing Accurate temperature forecasting is required

(deterministic/probabilistic)

Other variables : cloud-cover, possibly wind

Improve predictabiliy :

• Generation : monitor, forecast

• Flows : coordination of operation

Promote flexibility :

• DSM

• Storage

Develop and reinforce grid infrastructures (hardware)

Develop new mechanisms for a more intelligent power system (software)

Keys to enable an anergy transition
