Super SEL

Super SEL is utilised to directly decrease the sum of the minimum MW level or Stable Export Limit (SEL) of generators synchronized to the system by lowering the minimum generating level at a generator synchronised.

Interested Super SEL providers should contact [email protected] and outline their capability to provide the footroom service including but not limited to:

  • technical description of the assets

  • SEL reduction volumes which can be achieved where applicable including different operating mode configurations

  • date from which SEL reduction option is valid

  • minimum notice period required to achieve SEL reduction, noting we have set a maximum period of 6 hours

  • maximum period reduced SEL can be sustained

  • impact on ancillary services

  • Impact on reactive power range, inertia and response capability of the machine between ‘normal’ SEL and new lower SEL
