The Central Electricity Regulatory Commission (CERC) has issued a discussion paper proposing to reduce the scheduling timeline in the real-time market (RTM).
The objective is to better match demand and supply, reduce forecasting errors and minimise renewable energy curtailment. The paper proposed reducing the RTM bidding window from 15 minutes to 5 minutes. It also proposed reducing the 45-minute gap between RTM clearing and the commencement of power delivery by 15 minutes. As a result, the total timeline between the end of revision of schedule and actual delivery is proposed to be reduced from the existing 75 minutes to 50 minutes. This is expected to improve scheduling of intermittent renewable sources and help discoms avoid deviation settlement mechanism charges.
