Innovative Solution: Bulk Net

What is Demand Side Management?

Actions taken on the customer’s side of the meter to change: 1. Amount of energy consumption 2. Timing of use

Technology Innovation

Time-based pricing occurs in a variety of ways to influence our day to day decisions

Thousands of years of tradition of women not venturing out after sunset was broken, when STD tariff was slashed to 1/4th after 9 PM.

Pricing - most potent economic tool to change habits.

Why not electricity?

Agenda

Background



USA Case Study


Dynamic pricing has yielded positive results in 70 pilots around the world

International experience in Load Management/ Demand Response Programs

Dynamic pricing can take various forms

TOU is time-of-usePTR is peak-time rebateCPP is critical peakRTP is real-time

Technology boosts price responsiveness

Enabling technologies facilitate much greater demand response participation

Customer demand response can reduce U.S peak demand by 20%

Agenda

Background



USA Case Study


• Long Island Power Authority (LIPA) edge program is the largest residential/small commercial direct load control program using two-way communication in the United States

• Thermostats are centrally controlled in air-conditioning to achieve peak load reductions

• Two-way communication allows LIPA to monitor capability and response; it also enables customers to control their individual thermostats via the internet, a benefit that motivates participation

• About 20,400 residential and 3,000 commercial and small industrial customers are enrolled in the LIPAedge program, delivering about 25 MW of peak load reduction

5% reduction in peak demand = Rs.11,400 Cr

Conclusion

Bulk net would achieve DSM resulting in:

1. Reduced Capex2. Optimizing Energy cost3. Savings of diesel oil
