A process that allows the grids to “Acquire”demand-side resources at par with the supply-side resourcesAllows monetizing demand and energy benefits specific to feeder (choke points)Define program goals that are technology-neutral but that reflect the end-use load profiles and efficiency gainsPayments to implementing partners (Energy Service Providers) paid based on monitored kW and kWh savings

DSM Acquisition Options
Feeder-basedCompetitive Bidding
Standard Offer
• Utility issues RFP to acquire kW and KWh savings
• Selection done though evaluation of technology, proposed M&V and Rs/kW and Rs/kWh rate structure
• Payment terms usually linked to verified savings
• Implementers may get different Rs/kW and Rs/kWh rates
• Utility pre-determines price that is affordable to pay implementers (Rs/kW and Rs/kWh)
• Provides standardized M&Vprotocols for certain classes of programs
• Payment terms usually linked to verified savings
• Implementing organizations get same Rs/KW and Rs/KWh rates

Easier to implement, measure and monitorBenefits for certain feeders may be greater than othersCan involve local consumer groupsCan allow for implementation of distributed resourcesHelps integrate DSM into distribution planningFacilitates program scale up

1. Feeder identification
2. Data generation
3. Data analysis
-- Tri-vector metered-- Higher loading-- Load-shape –peak-demand
-- Consumer indexing-- Feeder revenue generation (cost-of-service)-- Seasonal demand and energy consumption
-- Current cost of service (Rs/KWh and Rs./KW)-- End-use efficiency, vintage, mkt availability
Presented by: Mahesh Patankar, PhD; ERGON 801/14/2010
6. Monitoring & verification
5. Tendering &implementation
4. DSM benefit-cost
analysis
-- Three levels –consumers, suppliers/providers and utility-- Simple pay-back, IRR calculations
-- Evaluation protocol to select private sector and NGOs/consumer groups-- Bid value for Rs/kW and Rs/kWh-- Timeline and benefits-- Options for utility, consumers and vendor involvement
-- Pre-determine feeder benefits Rs/kW, Rs/kWh-- Linked payment terms for savings

Consumers - benefits– Reduced electricity bills- New appliance/equipment stock- Multiple technologiesConsumer - costs- Monthly installments- Bidder payments
Utility - benefits– Reduced demand-charges to generators- Capacity offset- Reduced outages- Higher revenuesUtility - costs- Bidders payment- Upfront costs
Bidder - benefits– Increased market share- Assured payment with utility pass-throughBidder - costs- Implementation costs- O&M cost

Energy service provider activities have been limited to:◦ Single facility energy efficiency/demand savings
opportunities◦ Benefits sharing with facility owners alone .. leaving
utility markets outside the “benefits” equationDSM bidding would scale-up homogenous and heterogeneous feeders in a single bid:◦ Homogenous – multiple users on a Commercial or
Agriculture feeder◦ Heterogeneous – small-commercial, residential and
public sector end-uses
Presented by: Mahesh Patankar, PhD; ERGON 1101/14/2010
Residential feeders:◦ Mumbai – Reliance Infrastructure (solicitation still
open)Commercial feeders:◦ Commercial hubs in Mumbai – BKC .. consolidation
of HVAC load management related to a load of 50 MVa◦ Bangalore electronics cityAgriculture feeder◦ Karnataka – rural DSM◦ Maharashtra – concept-stage
