2. Climate Change @ TPDDL …Carbon footprint mapping and abatement strategy • Carbon footprint mapping for TPDDL done • Abatement levers identified- focus on procurement of Power from low emission factor Plants • TPDDL Climate Change Policy rolled out • Combat Climate Change team formed to oversee risks and opportunities and implement initiatives • CC Initiatives introduced as part of the BSC and cascaded to functional score cards …Tata approach, aspirations and internal stance • 7 Climate Change Champions trained, 31 Officers exposed to National seminars + 4 Climate Change Assessors • Over 2000 TPDDL employees touched in last one year • Participated in CII exhibition on Climate Change • Climate change newsletter started, carbon calculator on TPDDL website. • Energy booklet for Schools & Consumers. State level Climate Change Quiz & Debate organized. …Capability building and communications

3. Climate Change Initiatives • Under its Climate Change policy, TPDDL is committed to introduce energy efficient and greener technologies and identification of the mitigation & offset opportunities in a cost effective manner. • Various Initiatives taken under Combat Climate Change :- • Formation of DSM & EE(Demand Side Management & Energy Efficiency) Cell in 2009 • Energy Club for school students • Tree Plantation • Use of Battery operated vehicles • Solar Power (Installed capacity: 1.272 MW) • E Bill to consumers • Water Harvesting

4. DSM & EE-Journey So Far

5. Energy Efficiency Initiatives-Completed Projects Load Research • Load research carried out for residential consumers (10,000) in 2010 • Objective: To understand the end energy use & penetration of various brands, appliances among consumers • Based on the findings, identified following DSM program :- • Policy advocacy of Gas water Heaters • Appliance Replacement Program for Refrigerators & Air Conditioners • Awareness on star rated appliances

6. Energy Efficiency Initiatives-Completed Projects DJB Peak Shifting • First of its kind peak shifting project in consortium with water utility of Delhi, Delhi Jal Board (DJB). • After load profiling of TPDDL & DJB, suggested DJB to shift its morning operating hours (water pumping stations) by 1.5 hours, to minimize coincidence with TPDDL peak • Shift in the operation time was initiated from Aug ’09. • Continuous monitoring & verification in progress. • Key Benefits: • Shift of 2 MW load from TPDDL peak

7. Energy Efficiency Initiatives-Completed Projects LED for Advertising Hoardings • Metal halide Lamps (150 W) replaced with LED fixtures (40 W) at 10 TPDDL locations • Key Findings • 75% reduction achieved in energy load

8. Energy Efficiency Initiatives-Completed Projects Policy Advocacy Bank ATMs • Energy saving potential identified at Banks ATMs -ACs running 24 hours at 16-17°C throughout summer • Dialogues held with Ministry of Environment & Forest (MoEF) ;resulted in MOEF issuing guidelines to all the major banks in Delhi to ensure the optimal temperature setting of the ACs of their ATMs • Observed savings of 0.16 MUs during summer • Regular Monitoring &Verification in progress

9. Energy Efficiency Initiatives-Completed Projects LED Streetlights • 250 W HPSV lamps replaced with 100 W LED lamps for 18 street light fixtures on pilot basis. • Key Findings • Load reduction to the tune of 65% • In Discussion with Govt. Agencies to extend the initiative pan Delhi

10. Energy Efficiency Initiatives-Completed Projects LEDs-Indoor Applications • T12& T8 tube lights replaced with LED Tube lights (Number: 351) at corporate office • Key Findings • Load Reduction to the tune of 65%

11. Energy Efficiency Initiatives-Completed Projects Promotion of Star Rated Appliances • Appliance Replacement Program launched in association with LG, Voltas & Godrej • Offered Exchange Scheme, under which existing old Refrigerators and Air Conditioners can be replaced with new Energy Efficient BEE Star Rated Refrigerators & ACs • Consumers benefit-Reduction in energy bills, special discounts on market prices, good salvage value for old appliance • Scheme was available from 1st Aug, 2011 to 31st Oct, 2011 • Over 4000 star rated Appliances sold under the scheme

12. Energy Efficiency Initiatives-Ongoing Projects Bachat Lamp Yojana • Bachat Lamp Yojana (BLY) : CDM based scheme developed by BEE • Aims at large scale replacement of incandescent bulbs in households by CFLs • Under BLY, CFLs offered at Rs. 15 in exchange of working ICL bulbs (for residential consumers) • Tripartite agreement signed with BEE & C-Quest Capital to implement scheme in TPDDL area • Scheme launched in October,2011. Distribution completed at Motinagar & Mongolpuri Districts and commenced at Shalimar Bagh & Model Town on 16-01-2012. • CFL distribution under progress (over 4.5 lakh CFLs distributed so far)

13. Energy Efficiency Initiatives-Ongoing Projects DFID supported Appliance Replacement Program • TPDDL in association with BEE and ICF (consultant) developed an Appliance Replacement program for Refrigerators and Air conditioners • DFID (A UK grant agency) agreed to fund the expenses for Market Research, Stakeholder Workshops and Final report, for replication across India. • Expected to be launched in March ‘12. • Under the scheme, star rated refrigerators and ACs would be offered at the discounted rates (against the prevailing Market Operating Prices) & existing appliances would be bought back for the safe disposal • Target: 10,000 Refrigerators and 5,000 ACs
