Electricity Balancing Implementation

​​​​​​​​​​​​Projects for the early implementation of the European target for IN, aFRR, mFRR and RR

ENTSO-E has started work to set up the way forward to implement the European Platforms in line with the EB GL. Here you can find further information on:

Balancing and Ancillary Services Markets

Balancing refers to the situation after markets have closed (gate closure) in which a TSO acts to ensure that demand is equal to supply, in and near real time.

Efficient balancing markets ensure the security of supply at the least cost and can deliver environmental benefits by reducing the need for back-up generation. There is a desire to increase harmonisation of the rules for balancing and for using ancillary services in order to extend effective pan-European competition to these markets and increase efficiency. ACER has published Framework Guidelines on Electricity Balancing, which have served as a basis for ENTSO-E to develop the Network Code on Electricity Balancing.

An important aspect of balancing is the approach to procuring ancillary services. ‘Ancillary services’ refers to a range of functions which TSOs contract so that they can guarantee system security. These include black start capability (the ability to restart a grid following a blackout); frequency response (to maintain system frequency with automatic and very fast responses); fast reserve (which can provide additional energy when needed); the provision of reactive power and various other services.

Access to a broad range of services from a wide range of providers, including generators but also demand response (which involves customers changing their operating patterns to aid system balancing) gives TSOs flexible options, which allow them to make efficient decisions.

ENTSO-E’s Working Group Ancillary Services is working towards creating a harmonised approach to ancillary services provision by starting several early implementation Projects of the Electricity Balancing Network Code / Guideline:

CBA ISP

ENTSO-E conducted a Cost-Benefit-Analysis, in order to create a basis for a decision on the Imbalance Settlement Period(s) for Europe. Find more information and the CBA ISP in the final report.

Standard products for aFRR, mFRR and RR

ENTSO-E conducted a study on aFRR to – among others - find out possible implications of a shift from pro-rata to merit order activation. Find the study and its appendix here.

Standard Products Survey

The latest version of the standard products document was​ circulated to stakeholders in December 2016.

As announced in the BSG meeting in March, ENTSO-E suggests to conduct a survey based on this standard products document. This survey is targeted to European stakeholder associations and their members in order to refine the proposal for the list of standard products for balancing energy.

Stakeholders input would be appreciated​.

The answers, one per entity (for example one for each European stakeholder association and then one for each member), are expected before 12:00 on the 31st May (Central European Time). Company names are requested in order to avoid double counting but they will remain confidential.

Thank you for your participation!

Imbalance Settlement

Work to develop a proposal for harmonisation of the main features of imbalance settlement has been started.

Cross Border Electricity Balancing Pilot Projects

Pilot Projects have been defined to gain early experience in cross border electricity balancing cooperation. Regular updates are given here.
