CMP implementation

(Contractual) congestion

For BBL Company the guidelines on CMP apply in the event that BBLC has sold all its technical capacity and of contractual congestion. The guidelines on CMP introduce four mechanisms aimed at resolving events of (contractual) congestion by bringing unused capacity back to the market. The mechanisms are laid down in Exhibit G of the General Terms and Conditions Forward and Reverse Flow.

Actual CMP data is published on ENTSOG.

Oversubscription Capacity (OSC)

BBL Company will determine on a continuous basis for all Forward and Reverse Flow capacity products with a duration of one gas day or longer, whether additional capacity is available that can be sold. If additional capacity can be made available it will be added to the Firm Forward and Reverse Flow capacity available for auction on PRISMA.

Buy-back

BBL Company will apply a buy-back process if nominations exceed or are predicted to exceed physical capability and capacity on their side of the Interconnection Point. The buy-back mechanism will be an auction to buy-back capacity usage rights (nomination rights) via PRISMA. 

Surrender of Capacity (SoC)

A shipper can offer to surrender a standard capacity product via PRISMA in accordance with individual CMP rules on each side of the Interconnection Point. Following closure of an auction, PRISMA will inform BBLC how much capacity has been sold in each of their systems. BBLC will apply the priority rules to determine which surrendered capacity has been reallocated.

Long-term Use-It-Or-Lose-It (LTUIOLI)

The principles of LTUIOLI are that ACM and Ofgem require BBLC to partially or fully withdraw systematically underutilized contracted capacity on the Interconnection Point by a shipper when that shipper has not sold or offered its unused capacity and where other shippers request Firm Forward or Reverse capacity which cannot be honored because BBLC is sold out.
