Restoration Services

Restoration (formerly known as Black Start) is the process used to restore power in the event of a total or partial shutdown of the national electricity transmission system. 

Please note we have now published the Commercial Assessment Methodology used for the ESR Tenders found here and below

We contract for restoration services throughout the year.

We assess each potential provider’s capability, while also attempting to minimise distortion to the energy market.

This includes making an assessment of:

  • the potential to provide the required availability (i.e. maintain warm state) without exporting megawatts on to the network;
  • the ability to provide capability across zones and contribute to restoration timescales in neighbouring zones; and
  • the ability to start generating units independently if more than one is contracted at a physical location.
