Security of Supply Policies

We use several policies to manage the Security of Supply process.

Security of Supply Forecasting and Information Policy

The Emergency Management Policy (EMP) sets out the steps that we will take, as a reasonable and prudent operator, during an extended emergency.

We have prepared and published a Rolling Outage Plan and provided links to all approved participant plans.
