    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa Title: Waste Heat Utilisation Speaker: G C Datta Roy 1
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa DESL-Contributing EE & RE Development Globally Enabled energy saving of approx 200 MW in commercial buildings, industr ies and municipal facilities Designed and Engineered over 500 MW of biomass based power plants and cogeneration Designed and engineered 22 MW solid waste to energy plant Due Diligence & Project development for 250 MW of hydropower 400,000 LPD solar water heating in industrial processes 2
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa Talking Points in Brief • Context • Glimpses-global policy development • Few DESL case illustration • Drivers & barriers • Innovative barrier strategy 3
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa The Context Furnace video.mp4 “Although it can be tricky and expensive to harness, waste heat is getting increased focus as a source of power in both the U.S. and China, mostly because of the quantities of heat out there. A study conducted by Lawrence Berkeley National Labs estimated in 2005 that the U.S. alone has 100 gigawatts of untapped electrical capacity in the form of waste heat that annually could produce 742 terawatt hours of power. That's bigger than the solar fleet, which gets measured in megawatts.” Will waste heat be bigger than solar-Michael Kanellos-Greentechsolar; Jan 24, 2009 4
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa Japan “The Japanese Ministry of Economy, Trade, and Infrastructure (METI) has released its budget plan for the 2013 fiscal year. In it, METI outlines a 10.5 trillion yen, or over $124 million budget proposal to partially subsidize the purchase and installation of low-temperature waste heat recovery systems at various industrial plants around the country. Affected plants will be those that can reduce their energy consumption by at least 15 kiloliters of oil-equivalent. The amount of subsidy received will be dependent on the temperature of the waste heat recovered and be entirely dependent on interested plants and businesses completing the installations of such systems by the end of September 2013”.

    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa USA 6
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa Policy Interventions-Illustrative Examples Country Policies* Canada Depreciation of WHRPG accelerated by 50% Program ERSOP in Ontario: feed-in tariff of 70 €/MWh for the electricity produced from waste heat, for projects selected through calls for tenders USA Project to amend the federal law in order to allow 30% tax credit on WHRPG projects A dozen States have acknowledged that waste heat is a renewable energy source California (2011): investment aid of 0,8€/W, up to 3 MW (DSM) Japan Accelerated depreciation and soft loans Investment aid up to 50% Italy Extension of the scope of White certificates to include WHRPG, with a new scale in 2011: one certificate is now worth 60 €/MWhe ) Norway Investment aid up to 20% and tax exemption on the electricity produced and self used. *Panorama of public policies supporting power generation from industrial waste heat-ADEME, Oct, 2012 7
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa India Scenario-DESL Case Studies 8
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa Kiln-Sponge Iron Key financial ratios (Feasibility study) Investment-Rs 20 Crs Project tenure-10 years Power sale rate-Rs 3.34 to 3.51/kWh Project IRR -26.12% Equity IRR -37.79% Average Debt Service Coverage Ratio-2.09 9
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa Forging Furnace-MSME SME Steel Furnace (under implementation) Savings of PNG-24800 SCM/Year Financial savings-Rs 9.6 Lacs/Year Investment-Rs 2.0 lacs Simple payback-2.5 months 10
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa Industrial Boilers Boiler FG WHU recovery Brief summary of the project is as follows. Boiler capacity-5.6 TPH Steam pressure-16 Kg/cm2 g Exit flue gas temperature-210oC Various design modifications such as replacement with a higher sized economiser, installation of APH, installation of low pressure water heater were studied. As per recommendation, the unit implemented the economiser solution and derived the following benefits established by carrying out a performance test. Exit flue gas temperature reduced from 210oC to 132oC Gain in overall boiler thermal efficiency-8% Coal saving-1270 TPY Financial saving-Rs 45.7 lacks per year Cost of additional economiser-Rs 25 lacs Payback-< 6 months 11
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa India Scenario-High Potential-Very Low Penetration (DESL database-2012) Sector Application Penetration Cement Preheating High WHR STG system Low Integrated steel GTG One demo project Hot gas recuperators High Sponge iron Preheating Low WHR STG system Low Steel furnaces Recuperation Low Other metal furnaces Low Glass furnaces Recuperator Low WHR STG system One CDM project VAM Low Paper Hood PV system Medium Sugar/Biomass power Bagasse/Fuel drying Low Refineries FCCU recuperator High WHR STG system Not known Boilers Economisers/APH High (Partial gain) Low Temperature Low 12
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa India Scenario-WHRPG System About 70 projects overall against 900 in China* India yet to promote specific policy for WHU-PAT is likely to be a potential driver *ADEME report 13
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa Drivers & Barriers-(Recent Analysis) Drivers • Economics (Energy prices, Energy cost indices, Energy availability & quality) • OE (for MSME)/Peer (Large scale) pressure • Compliance Barriers • Low awareness-quantification of opportunities (market overall & individual units) • Technology-real & perceived risks • Lack of warranty services- Sustaining initial gain • Market uncertainty-impact on return • Regulatory Unlike in such cases, successful demos/pilots do not seem to have made desired impact 14
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa Barrier Strategy • Assessment of the market opportunities – Grades (High, medium & low temperatures) – Sectors – Technologies (Process, Power, VAM, ORC) • Common strategy – Awareness & promotion – Policy development & deployment – Demo projects • Need for strategy innovation 15
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa Proposed Strategy Innovation • WHR Alliance (Cluster, Sectoral, National) Units /Clusters/ Sectors Vendors BEE/SDAs Banks/FIs Service providers Technical Institutes OEM (MSME) 16
    • The 14th Regulators & Policymakers Retreat 1st – 4th August, 2013, Goa Marriott Resort & Spa, Goa Conclusion • WHU-Next big thing in the EE domain • Overall market potential high but not yet quantified-need for market assessment study • Penetration very low even in the relatively better identified markets • Need for innovative strategy-WHRA proposed under the USAID sponsored PACE-D project (Capturing the learning from the successful development of ‘Appliance Standard’ &‘Green Building’ markets in India) • Process initiated in one of the MSME Furnace cluster • Successful implementation can catalyse faster development of the WHU market 17
