4 II. CMP: Common methodology of OSBB for the Region. II.2 Strategy in the Region Regulators welcome the improvements of the OSBB methodology. Some additional aspects should be analyzed: 1.Restriction of renominations when the BB is launched. This measure introduces rigidity, taking into account counterflows and a cap to the price TSOs pay for buying back capacity. It is important to study how this measure affects users which acquired yearly, quarterly and monthly products. 2.It is not clear how the pro-rata mechanism would apply when the BB procedure cannot provide the reduction of nominations required by TSOs, as well as which users are affected. 3.The most efficient BB mechanism must be chosen by the TSOs (call for offers versus reverse auctions). The mechanism must be as simple and efficient as possible to guarantee that a OSBB mechanism is correctly designed to lead a low use of the BB procedure.

5 II. CMP: Common methodology of OSBB for the Region. II.2 Strategy in the Region Some additional remarks from ACER: General: OSBB mechanism is proposed for short term (DA). Possible to extend for longer periods (months, quarters)? Restricting nominations: Limit of the use of capacity? Possible cases of shippers’ gaming? What rules of BAL NC could not be respected? Pro-rata mechanisms: A fair solution could be: 1.First TSO buys form the BB market. 2.If quantity is not enough pro-rata to all shippers based on the net quantity after the BB market allocation. Clearing prices: why not pay-as-bid instead of marginal price?
