Outage Planning Reporting

Planned loss of supply and reduced security outages

This report provides a forward view of planned transmission outages that could involve a planned a loss of supply or n-security to our connected customers. We are providing this in addition to our usual outage communications and notifications. For up-to-date outage information, please use POCP (Planned Outage Co-ordination Process) https://pocp.redspider.co.nz/ which is updated every hour.
