The Ministry of Power (MoP) has issued a draft proposal on day ahead operation of security constrained economic despatch (SCED).
The draft proposes to enlarge the scope of SCED to include more plants and to run the SCED on day ahead basis. As per the draft, the generating station shall submit their declared capability along with ramp rate and minimum turndown level for the next day on D-1 by 6am. Regional load despatch centres (RLDCs) would prepare the entitlements and declare the share of each beneficiary by 7 am. The energy charge rate/compensation charge to be considered for SCED shall be submitted by the generating stations on a monthly basis. The day ahead market (DAM) shall be cleared by 1pm and power exchanges would convey DAM results to national load despatch centre after clearing of market. The ministry has sought comments and suggestions on the draft by February 22, 2023.
