Overview
To book capacity on PRISMA, you need at least one assignment to an operator: a Transmission System Operator (TSO), a Storage System Operator (SSO) or a Liquefied Natural Gas System Operator (LSO). After your organisation registers on PRISMA, the shipper admin requests assignments to the operators your organisation wants to book capacity from.
Each assignment has two parts. The organisation assignment covers your company, and the user assignment covers you as an individual user. You need both to book capacity with that operator.
Operators do not approve assignments automatically. Each operator sets its own registration requirements, which you can check on the Market Participants page.
For further information on requesting an assignment, please consult: How to Request Assignments to Operators?
Viewing Your Assignments
To view your assignments, do as follows:
- Log into PRISMA.
- In the left sidebar, click Operators, then Assignments.
PRISMA shows a table of your assignments, with one row for each operator and user.
The Assignments page under Operators, listing each assignment with its Organisation Assignment Status and User Assignment Status.
The table has the following columns:
| Column | What it shows |
|---|---|
| Operator | The operator the assignment is with. |
| Organisation Assignment Status | The status of your company's assignment with the operator, and whether it covers the Primary Market, the Secondary Market, or both. |
| User Name | The user the row refers to, with their email address. |
| User Assignment Status | The status of that user's assignment with the operator. |
| Actions | The Details button, which opens the assignment details page. |
To narrow down the list, click All, All Active or Own Active above the table, or click the filter icon at the right of the Active Filter bar. To export the list, click XLSX below the table.
