SPG Grid Suspension

This process is used to suspend the service providing group (SPG) temporarily.

The suspension is valid for the following combination:

• service providing group- the SPG that is suspended.
• impacted system operator- the one that suspends.

All procuring system operators will be affected by the suspension as the SPG will no longer be approved to deliver services. Procuring system operators and impacted system operators will receive notification of the suspension.

Suspension is a powerful tool, and might not be the right way to limit the use of a SPG. A SPG grid suspension will effectively prevent the SPG from delivering any services to any PSO. The ISO must consider using softer tools such as temporary limits.

Reasons for suspension:

Reason	Description
breach_of_conditions	The SPG grid prequalification status is conditionally_approved and SPG repeatedly breaches the conditions.
significant_group_change	In cases where the SPG is altered significantly and ISO needs time to consider if they need to do a new grid prequalification or use other tools.
other	Should generally not be used, but can in cases where ISO has a valid reason for suspension that is outside the other defined reasons.

The process also includes reinstatement of the service providing group grid prequalification, i.e. removing the suspension.

Prerequisites

• The issue that triggers the suspension is temporary.
