FCFS Capacity - How To Book FCFS Capacity?

Modified on:: Tue, 9 Mar, 2021 at 10:15 AM



On PRISMA, you can also book certain capacities on a first-come-first-served basis. The platform acts, therefore, as an intermediary between shipper and TSO with regard to all booking information (e.g. request, confirmation of availability).


  1. Capacity is sold at the regulated tariff;
  2. The user requests a certain amount and the TSO checks whether the requested amount is available;
  3. If the requested capacity is not available, the TSO may send alternatives, which will be automatically generated on the platform.

NOTENot all TSOs offer FCFS capacity.


To find the FCFS Booking page, do as follows:

  1. Click on "Transport" at the top blue menu;
  2. Then, click on "FCFS Booking" in the white menu just below.

Step 1: Select the network point: select the network at which you would like to book capacity. Begin typing and click on the right suggestion in the pop-up menu.

NOTE: You do not have to be logged in order to check whether any capacity is available, but to confirm a booking you will be asked to log in.

Step 2: Specify Booking: After choosing a network point, you must specify the details of the capacity you would like to book. You must specify:

  1. The capacity category;
  2. The amount of capacity;
  3. The runtime.

Step 3: Confirm: If the requested capacity is available the process continues and you can confirm your booking. Any trade proposals that match your request will also be displayed. You will be able to select these as alternatives.

  1. If the specified capacity is not available, the TSO may suggest alternative capacities that partially cover your request.
  2. If no alternative capacity is available, you will not be able to continue and if you still wish to book capacity via FCFS you must start a new booking with different specifications.
