Black Start

Black Start is the procedure we use to restore power in the event of a total or partial shutdown of the national electricity transmission system.

04.02.20 Please note we have published our Black Start Strategy and Procurement Methodology for consultation until 4th March 2020. Please review the Methodologies content below.

We contract for black start services throughout the year.

We assess each potential provider’s contribution to black start 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 black start 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.
