MARI - mFRR Platform Design - First Consultation - Call for Input

Closed 20 Dec 2017

Opened 21 Nov 2017


This consultation deals with the design aspects defined by the MARI (Manually Activated Reserves Initiative) project which aims at setting the common European manual frequency restoration reserves (mFRR) platform following the Guideline on Electricity Balancing (GLEB), approved by EU Member States on March 16th 2017 and expected to enter into force in winter 2017/2018.

The involved TSOs (19 members, 10 observers) see the task of the creation of one European wide mFRR platform as crucial for the establishment of an efficient and liquid European balancing market. Furthermore, the MARI project was designated as the European implementation project for the mFRR platform by ENTSO-E.

Why your views matter

TSOs involved in the MARI project are presenting in this consultation different design options for the mFRR platform and are seeking input from stakeholders and market participants on those design aspects relevant for them. Your feedback on the design options will be highly welcome and will help TSOs to prepare the proposal for the final design of the mFRR platform.

The MARI members are initiating this voluntary open online consultation for a period of 1 month (21 November 2017 – 20 December 2017).

What happens next

The feedback from this online consultation will be carefully analyzed and considered while creating the design of the mFRR platform.

In a second step, the selected options  concerning the mFRR platform design will be presented and consulted according to the GLEB approx. in summer 2018.
