TPDDL Profile

• Joint Venture of Tata Power Company and Govt. of NCT of Delhi (51: 49)

Licensed for distribution of power in North and North

West Delhi

3 5/10/2012

• The Tata Power Company Ltd. and

Govt. of Delhi JV (51:49)

• License Area : N. Delhi- 510 sq. km

• Consumer Base : 1.25 Mln ; serving

population of 5 Mln

• Peak Load Served : ~ 1400 MW

•Tata Power Delhi Distribution : ISO 9001,

14001, 27001 ; SA 8000 Certified

TPDDL’s journey so far ….

At the time of inception

• AT&C Losses at a level of 53%

• Unreliable Power Situation - transformer failure rate of 11%, only 48% streetlights functional, power cuts of 8-10 hrs/day with 10-12 hrs in summer

• No Concept of Consumer Service

• Erroneous consumer and asset database

• Lack of Performance orientation

• No Computerization / Automation / Tracking and Monitoring

Current Scenario

• AT&C Loss level : 13.5% -- unprecedented reduction of 75% from opening loss levels

• Power Reliability improved manifolds – transformer failure rate 1%, 99% streetlights functional, power cuts negligent despite continuous load growth

• One Stop solution for consumers- State of Art Call Center and Consumer Care

• GIS implemented – 100% Assets and consumers mapped

• Performance Orientation through • Change Management • & Balanced Scorecard Approach

• Integrated CRM introduced, Automation roadmap implemented (SCADA, OMS, DMS, DA implemented)

(Achievable) 5% Reduction in peak demand through DR

(Achievable) 10% Reduction in peak

In 2011-12

• Peak Demand - 152.746 GW

• 5% reduction - 8 GW

• 10% reduction - 16 GW

Demand Response (DR)

Demand Response (DR) is Peak Electrical Load Reduction, an historical perspective and business model for load control

Demand Response explicitly refers to all those activities that involve utility action in the marketplace to modify the consumer's load profile through Consumer participation. Demand Response is a potent tool to address the peak energy and power deficit in India which stands at 12.1% and 10.6% respectively.

5/10/2012 8

Why Demand Response??

A. Gap between Demand side and supply side may be met by:- 1. Increasing the Generation Growth 2. Reducing the Load Demand

B. Time, Resource and Capital Requirement issue can be addressed easily- crucial for Developing nations.

C. Operational Concern addressed – Virtual Peaking Generator D. Aligned with the Climate Concern

5/10/2012 9

Automatic Demand Response (ADR) is an integrated system with energy management control systems to initiate customer approved actions to curtail loads automatically during requirement of Grid. An Auto-DR event can be triggered by either real-time prices or system reliability triggers. The communication is based on open standards like Internet protocols – Open ADR protocol.

Utility

Facilities

Facilities Aggregator

Automatic Demand Response (ADR)

Infrastructure Model

• Utility will have direct customer relationship, contract and pay incentives

• Utility will design, develop, market and program manage the DR program

• Utility will engage DR infrastructure provider to provide multiple services like Auto DR infrastructure, Facility Commissioning and Shed strategy, BMS programming and management, customer training and problem resolution

DR Aggregator Model

• Utility will not have direct customer relationship

• Utility will engage service provider to provide Turnkey DR services like Auto DR infrastructure, BMS programming and management, customer training and problem resolution, design and development of DR program, incentive payment, DR program marketing and management, customer web portal, delivery of peak demand reduction

Smart Metering is one of the cornerstones of Smart Grid Vision as it:

Allows customers to make informed decisions by providing highly detailed information

Provides customers with greater control over their electricity use when coupled with time-based rates, potentially saving money on their monthly electric bill.

Allows for faster outage detection and restoration of service , reduce call centre cost

Increases privacy because electricity usage information can be relayed automatically to the utility for billing purposes without on-site visits

handling

Customer Information for utility • Comprehensive life sheet of • consumer consumption • Faster complaint redressal • Remote notification &

escalation • Timely bill & payment alerts

Information for utility/customer

• Overall power‐usage information (meter reads)

• Power‐usage pattern information

•Granular information about power usage by

devices inside the home

• Meter consumption reports

• Load profiling & history of usage

• Dynamic pricing peak/non-peak

Meter Maintenance • Remote meter health

check • Tamper proof • Remote firmware

upgrade

•Smart‐meters along with AMI Modems or the Meters having capability to

communicate data over a media
