Public consultation on the design proposal for the pilot project BidLadder


In case of residual imbalance in the Belgian control zone via the balancing market Elia calls upon both reserved (like contracts for R3 Production, R3 DP and ICH) and non-reserved power (so-called “free bids”). Today such free bids can only be provided by remaining flexibility on large production units (so-called “CIPU-units”).

Elia’s ambition is to also create the possibility for offering free bids on the balancing market from flexibility coming from grid users, aggregators and smaller production units. 

To realise this Elia created the pilot project BidLadder aiming to provide all market parties with a bidding platform by 30 June 2017, in a first stage for the delivery of flexibility to the balancing market from delivery points in the Elia grid, and later potentially – after deliberation with the DSOs - from delivery points connected to the distribution grid.

In a design note Elia describes the pilot project BidLadder, including a concrete solution for arranging the so-called Transfer of Energy. This solution, which builds on the conclusions on the Transfer of Energy mechanism made by CREG in its study 1459, makes it possible that grid users, via a so-called Flexibility Service Provider, can easily bring their flexibility to the market without requiring preceding arrangements with their supplier or without needing to become themselves Balance Responsible Party for their access/delivery point.

This note (NL / FR) is now subject to public consultation until 8 September 2016. The final version of the note will be submitted to CREG together with the consultation report.

Practical details for participating to the public consultation can be found on the Elia website.
