Loss of load probability and de-rated margin (LOLPDRM)

The loss of load probability and de-rated margin data is received half-hourly from NGESO.

Loss of load probability (LoLP) is a measure of system reliability, calculated by NGESO for each settlement period, using the methodology set out in the Loss of Load Probability Calculation Statement.

De-rated margin is a forecast of the excess supply on the system, which has been adjusted to take account of the likely availability of electricity generators.
