Using regulation capacity

This page details the history of the ancillary services used to maintain balance in Elia’s control area, as well as the activated strategic reserve used to ensure adequacy in the Elia’s control area.

GDV= the gross Downward regulation Volume, i.e. the sum of all downward regulation actions requested by Elia in a given quarter-hour;
GUV= the gross Upward regulation Volume, i.e. the sum of all upward regulation actions requested by Elia in a given quarter-hour;
NRV= the net Regulation Volume in a given quarter-hour, equal to the difference between the gross upward regulation volume and the gross downward regulation volume.

MIP = the highest price of all upward activated products for the quarter-hour in question;
MDP= the lowest price of all downward activated products for the quarter-hour in question;
NRV= the net regulation volume in a given quarter-hour, equal to the difference between the gross upward regulation volume and the gross downward regulation volume:

  • If this is positive, the MIP is applied in the tariff for balancing energy.
  • If this is negative, the MDP is applied in the tariff for balancing energy.


Important disclaimer: When the strategic reserve volume that is activated is bigger than 0 MW, in the prices table the columns MIP, IGCC+, R2+, Bids+, R3+, MDP, IGCC-, R2- and Bids- will not be used for the calculation of the imbalance prices, when a activation of strategic reserve is on-going. The imbalance price will be in the column with the SR. To understand how those imbalances prices are calculated during a SR activation, please consult § 6.7.2 of the Functioning Rules.

Balancing

Both the quarter-hourly price and the quarter-hourly volume are given for each product category (if the product was actually used). Only regulation-related measures requested by Elia with a view to offsetting imbalances in the control area are included.

Prices

The prices given on this page are:

  • the highest price Elia paid during the quarter-hour in question in the case of upward regulation;
  • the lowest price Elia received during the quarter-hour in question in the case of downward regulation

A new method for calculating the tariff for balancing energy has been used since 1 January 2012.

Product categories

IGCC -         exports to neighbouring Transmission system operators in case of positive imbalances
IGCC + imports from neighbouring Transmission system operators in case of negative imbalances

R2-

secondary reserves activated downwards

R2+

secondary reserves activated upwards

Bids-

non-contracted regulation reserves activated downwards

Bids+

non-contracted regulation reserves activated upwards

R3-

tertiary reserves activated downwards (emergency contracts with neighbouring transmission system operators)

R3+

tertiary reserves activated upwards (tertiary reserves for generation and offtake, and emergency contracts with neighbouring transmission system operators)

SR

Strategic Reserve activated, for more information see the submenu “Strategic Reserve”
