demand side management
This presentation discusses demand side management (DSM) in the Indian power sector. It notes that while India has significantly increased its power generation capacity, demand continues to outpace supply, leading to energy deficits and load shedding. DSM aims to balance supply and demand through strategies like controlling energy usage during peak times and load levelling. Examples provided include interruptible loads and incentivizing off-peak usage. Barriers to DSM include a lack of public information and support mechanisms. The presentation outlines a DSM planning process and concludes that widespread adoption of DSM through energy efficiency, new technologies, and load management could help reduce load shedding issues caused by current energy and peak power shortages.

- 19. What consumers doduring load shedding • They suffer, silently and helplessly • Some have invested in diesel generators • Many have purchased inverters • This is expensive for the middle class and out of reach for the poorer section of society • They cater to a part of the lighting load only • Difficult to run refrigerators, water pumps ,AC • Inverters are energy guzzlers – Consume nearly twice the energy to charge their batteries after they have been used – Further increases the loss due to harmonics 19
- 20. Load management usingload rationing is actually an effective way forward for Demand Side Management It will be a far more effective and a sure way to manage peak demand at the time of shortages as compared to influencing consumer behavior using TOD tariffs It will help in conserving energy The energy consumed by the batteries of the innumerable inverters will also be saved. 20

Editor's Notes
- #4 Future of demand
- #9 avoid waste and cost - associated with dialling down electricity generation beyond critical points
- #10 Annual effects – metricDirect load control – control of individual appliances (AC)Interruptible load – contractual agreements allow for disruption of certain customer’s service during peak loads by direct controlOther Load Management – time-of-use rates, load limiting devices, water heating storage systems, cool storageEnergy efficiency – aimed at reducing specific end-use devices and systems, without affecting services. Usually does not explicitly pay attention to time-of-use. Technology
