Power Chronicle - EAL Newsletter - Volume 02 Issue 01

SCED framework, rolled out on 1st April 2019 on a pilot basis, is expected to enhance the spirit of competition and efficiency, as enshrined in the Electricity Act 2003, with measurable gains in terms of savings due to optimisation of power procurement portfolio for ISGS plants. EAL estimates daily savings to range between Rs. 0.5 to 10.5 crores for the two weeks analysed for this newsletter. EAL's analysis of the increment and decrement pattern across ISGS plants highlights the outcome of optimisation in terms of increment/decrement in schedule for plants with lower/higher variable cost.Based on higher cost savings using a multi-period optimisation model developed by EAL, we recommend that POSOCO can also adopt a similar framework wherein the SCED model is run prior to each time block while also considering the latest available schedule for rest of the time blocks in an identified rolling window. EAL is also developing a web-based tool to share the outcome of its SCED model through its portal. The current SCED framework captures room for optimisation within the ISGS generation schedule provided by the beneficiary discoms. Expansion of the list of eligible generators would take us a step closer towards a nationwide wholesale market providing for nationwide optimisation of power procurement cost. Learnings from SCED would help achieve that goal. EAL has been providing power system and power market snapshot and analysis to the stakeholders. We invite your suggestions to strengthen and empower decision making in the Indian Power Sector
