The bidladder, a closer look
In essence, the BidLadder is a platform operated by Elia gathering different (kinds of) bids for balancing energy. In its ultimate form it will provide control engineers with an overall ranking for balancing energy, in particular all R3-related products, whether reserved or non-reserved. Opening market access to balancing service providers will give Elia greater liquidity in the balancing energy market, which is also positive for the community and in terms of integrating RES into the Belgian grid.
The BidLadder, combined with a transfer of energy (ToE) solution, enables BSPs like independent aggregators or grid users to offer Elia flexibility for balancing purposes, whereas today this option is only open to large generating facilities (such as CIPUs).A transfer of energy for the market of tertiary non-reserved control power is foreseen in April 2018.
This transfer of energy solution will ensure that market parties (i.e. BSPs), that are not necessarily suppliers or balancing responsible parties, can participate in the balancing mechanism by offering their flexibility to Elia
