Short Term Adequacy (STA)

Short Term Adequacy (STA)

Supply and demand of electricity must be continuously maintained. Consequently, adequate capacity must be ensured at all times, in order to cover for demand requirements, including the need for reliably responding to abrupt outages of generation and/or transmission equipment. To this end, the capacity of readily available resources must always be greater than the consumption that is to be served.

Further to the above, potential constraints of transmission capacity may limit the ability to transport the generated electricity to consumption points. Therefore, TSOs need relevant forecasts/assessments on the availability of generation resources and of situations where transmission congestion(s) may arise due to the regional distribution of generation capacity and consumption.

SEleNe-CC, as the RSC for the SEE CCR, performs adequacy assessments on the basis of the information provided by SEE TSOs, with the aim of detecting situations where a lack of adequacy is expected in any of the control areas or at regional level, taking into account possible cross-border exchanges and operational security limits, as per Regulation 2017/1485. These SMTA forecasts are effectively based on information regarding the generation availability, consumption levels and expected state of transmission corridors with weekly forecast horizons.
