Day-ahead auction with delivery on the French TSO zone
Size
The minimum volume increment is 1 MW.
Tick
The minimum price increment is EUR 0.01 per MWh.
Underlying
Electricity traded for delivery the following day in 24 hour intervals.
Special case: the switch to and from daylight saving time is transparent for the members as the trading system automatically doubles the quantities for hour 03 (i.e. 3.00 am) when the clocks are reset to daylight saving time and deletes the exceeding quantities when they are switched back to winter hours.
Place of Delivery
Deliveries are made within the French transmission system managed by RTE.
Auction hours:
The daily auction takes place at 11.00 am, 7 days a week, year-round, including statutory holidays.
Publication time
The auction results are published as soon as they are available and in every instance, before 11:45.
Type of orders
Individual hours
Orders contain up to 256 price/quantity combinations for each hour of the following day. Prices must be between 0.01 €/MWh and 3000 €/MWh. The 254 prices are not necessarily the same for each hour. A volume – whether positive, negative or nil – must be entered at the price limits. A price-inelastic order is sent by putting the same quantity at the price limits.
Blocks
Block orders are used to link several hours on an all-or-none basis, which means that either the bid is matched on all of the hours or it is entirely rejected. Block orders have a lower priority compared with single hourly orders. The quantity must be the same on all applicable hours.
Standard block orders:
- Block Baseload covering hours 1 to 24
- Block Peakload covering hours 9 to 20
- Block Night covering hours 1 to 6
- Block Morning covering hours 7 to 10
