1.    Simple Orders

Simple Orders are composed of step segments, separately for each MTU of Delivery Day D. The specified curve is increasing for Sell Orders and decreasing for Buy Orders. A Simple Order consists of at least two and not more than 50 Price quantity pairs, where a “Price Quantity Pair” (“PQ pair”) specifies a price and a quantity of electricity for sale or purchase in a specified MTU. PQ pairs in a Simple Order are to represent a step-wise function of price and quantity of energy for sale or purchase in the specified MTU, with either an incremental or decremental quantity of energy specified at each price step.


Priority Price‐Taking Sell Orders are Simple Orders priced at the minimum accepted price in the Day-Ahead Market, i.e. at the Minimum Price of Day-Ahead Market. Priority Price‐Taking Buy Orders are Simple Orders priced at the maximum acceptance price in the Day-Ahead Market, i.e. at the Maximum Price of Day-Ahead Market

(a) a fixed price limit (minimum price for Sell Block Orders and maximum price for Buy Block Orders),
(b) an energy quantity for each of the MTUs included in the Block Order, and
