Coordinated Capacity Calculation

Within the Coordinated Capacity Calculation (CCC) task, Baltic RCC determines available cross-border transmission capacities between bidding zones in the Baltic region. These calculations consider system security and previously allocated capacities across various electricity markets.

The process uses the Common Grid Model (CGM), built from Individual Grid Models (IGMs) provided by TSOs. In coordination with TSOs, RCCs perform daily data quality checks, merge inputs, and determine net transfer capacities and available transfer capacities. Baltic RCC performs the CCC task across six timeframes: intraday, day-ahead, week-ahead, month-ahead, quarter-ahead, and year-ahead.

CCC is a key component of the European interconnected electricity system. It ensures reliable capacity calculations and delivers optimised results to market platforms, enabling secure and efficient cross-border electricity trading.
