Institutionalization of Training and development.
Challenges in Power Sector 5/10/2012 6
Peak Demand GW Demand Response - Market Potential India Market DR Potential Business-as-Usual (No DR) (Achievable) 5% Reduction in peak demand through DR (Achievable) 10% Reduction in peak demand through DR Maximum Achievable In 2011-12 Peak Demand - 152.746 GW 5% reduction - 8 GW 10% reduction - 16 GW 5/10/2012 7
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) 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. Facilities Utility Aggregator Facilities 5/10/2012 10
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 Demand Response (DR) 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 5/10/2012 11

Smart Metering for ADR 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
Current Metering Scenario at TPDDL Consumer Segment Xpress Consumer Key Consumer Profile DJB, DMRC, Malls etc. LIP, Hospitals, Institution Sanctioned Load > 499 KW > 99 KW % of TPDDL Consumer(Nos) 208 (0.02%) 1649 (0.14%) Meter Type HT Meter HT Meter Reading Type AMR AMR HRB Consumer SIP,Towers, Street light etc. 11 KW to 99 KW 34087 (2.88%) CT Meter AMR HCB Consumer Household, Shops & Agriculture 1 KW to 10 KW 1018545 (85.98%) Single Phase HHD G & I Consumer Government & Institutional Consumers All Load 9361 (0.79 %) HT/CT/Prepa id Meters AMR HHD (Prepaid only) SCG Consumer JJ Clusters 2 KW 120779 (10.20%) Single Phase Group Meter Spot Billing 5/10/2012 14
Automatic Meter Reading at TPDDL Existing set up: 48000 meters are on AMR which serves 3% of the total consumers generating 60 % of total revenue GSM based CSD technology Challenges: Communication reliability Scalability (Capex, Opex, technical) Real time monitoring 1 way communication system 5/10/2012 15
AMI Meter Operation Real time meter reading Remote meter reading Remote connect & disconnect Interval metering Automated & timely billing Data storage Pre-payment metering Load Management/Outage handling 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 Customer Information for utility Comprehensive life sheet of consumer consumption Faster complaint redressal Remote notification & escalation Timely bill & payment alerts Meter Maintenance Remote meter health check Tamper proof Remote firmware upgrade
Smart metering solution framework Smart meters along with AMI Modems or the Meters having capability to communicate data over a media A Communication media that carries Data from Smart meter to designated Server (or a Data Centre) and An Enterprise Application Suite (like Data Acquisition Software, Meter Data Acquisition, SAP FICO /MM etc.) that helps process the data for billing /invoicing and other organization control & integration process
