Short-Term Adequacy

The Short-Term Adequacy (STA) process assesses the power system’s ability to reliably meet the electricity demand, considering the real-time nature of electricity generation and the limited capacity for energy storage. Baltic RCC evaluates the sufficiency of available generation and potential constraints in electricity transmission. If a shortfall is detected, measures are implemented to prevent an adequacy issue.

Ensuring adequacy requires that available generation capacity always exceeds expected demand, even in the event of sudden outages of generation or transmission assets. This continuous balance is critical for maintaining system security and operational stability under all conditions. To achieve this, TSOs rely on detailed forecasts and thorough assessments of generation availability and potential transmission constraints, which are essential for safeguarding system security and stability.

Regional STA is run in case of an adequacy issue detected during the pan-European process in the Baltic region. The process ensures detailed analyses of adequacy issues to be investigated by Baltic RCC and Baltic TSOs. Baltic RCC provides regular reports on the Baltic power system adequacy status to the Baltic TSOs.
