In general, ES capacity value is determined by the plant''s ability to support demand under outage conditions – in this case, single and double network faults. It follows that a key factor in determining ES contribution is the duration of outages; the longer the outage duration, the more energy is required from ES.
For example, at the peak time, the benefit is £205.2/MW/yr for the 30MWh case at load level 20 MW, which increases almost 7 times to £1191.7/MW/yr at load level 60 MW. In terms of reinforcement deferral, the 20MWh case can defer 5.6 years while with the case of 30MWh it can defer 6.3 years. Table 2.
