1 Technologies Waste to Energy JP Hoffman Siemens

2 Proprietary Information Of Energy 2013 – Why WtE? – Before Putting Into Service – Challenges – Opportunities – Risks – Rewards – Lessons Learned Agenda Waste Material Utilization: Reuse, Recycle, Energy Recovery tml

3 Proprietary Information Of Energy 2013 Why Waste-to-Energy? Benefits Reduce U.S. dependence on fossil fuels Increase energy security Reduce GHG emissions Meet future policy emissions controls

4 Proprietary Information Of Energy 2013 Reduction of GHG Avoided methane emissions from landfills Avoided CO2 emissions from fossil fuel combustion Avoided CO2 emissions from metals production Water Use Discharges Environmental Aspects 1 1 –

5 Proprietary Information Of Energy 2013 Solid Waste Generation MSW Waste-to-Energy generation creates a solid waste called ASH Depending on state and local restrictions, non-hazardous ash may be disposed of in a MSW landfill or recycled for use in roads, parking lots, or daily covering for sanitary landfills Environmental Aspects

6 Proprietary Information Of Energy 2013 Before Putting into Service Applicable Concept and Design Feedstock management Design/Build/Operate/Maintain Agreement Environmental Considerations Air Emissions Permit Water Use/Discharge Permit Environmental Impact Requirement Regulatory Conformance Preliminary Requirements 1 1 –

7 Proprietary Information Of Energy 2013 Before Putting into Service Siting Permits Waste Availability/Supply Commitments Ash Disposal (landfill) Capacity Financing Options Contract Vehicles / PPA / EUL Incentives & Guarantees Exploration Expense Tax Credits Preliminary Requirements 1 1 –

8 Proprietary Information Of Energy 2013 Public Opposition Environmental groups often form opposition against new WtE plants regardless of technology used Need to understand the impact this may have on permitting process, utility process and financing options Understand timeline for public notification Technical and Performance Issues System must meet performance criteria to remain economically viable Newer, more experimental systems are risky because they have no demonstrated performance records Facing Challenges

9 Proprietary Information Of Energy 2013 Cost Challenges Exploration New Infrastructure New Generation Plant Waste Stream Supply Issues Lack of supply could void any third party guarantee Funding and Financial Issues Changes in government contract vehicles and/or restrictions Lack of seed money for start-up projec ts Facing Challenges

10 Proprietary Information Of Energy 2013 Scale Issues Long term growth must be considered when determining applicable size of plant Smaller scale projects have higher levelized costs of production Lack of Support for Decision Making Lack of defined, documented economic, environmental, and technology performance metrics to inform the decision-making process and states’ varying definitions of municipal solid waste, biomass, and WTE Facing Challenges

11 Proprietary Information Of Energy 2013 ACHIEVE ENERGY MANDATES Energy security and availability Promotes long-term affordable energy prices Reduces waste stream direct and indirect costs Tipping fees of disposal New landfill cell opening fees Transportation costs Labor costs New Opportunities Provides base-load power Augment on-site intermittent renewable energy generation technologies Solar and Wind Unconsumed/overproduced electricity could be sold to the utility Valuable by-products for use in other areas Bottom ash Biogas Bio-char Bio-oil

12 Proprietary Information Of Energy 2013 Under-trained staff performing incorrect operation and maintenance procedures Improper O&M can cause low production or failure of systems Energy price escalation Evolving energy landscape leads to difficulty forecasting energy prices Utility energy pricing fluctuation based on market conditions Waste Stream Supply Intended use of buildings may change over time Conservation methods may change volume or type of waste stream produced Understanding Risks

13 Proprietary Information Of Energy 2013 Changing Emissions Standards/Environmental Legislation Increasingly stringent emission standards may create future costs to comply if goals are not aggressive enough in design Plant Equity Useful life is considered to be 20+ years – Current market estimate at 20+ years Understanding Risks

14 Proprietary Information Of Energy 2013 Contract Clarification Risk Responsibility Matrix Understanding of scope of supply, limits of liability, liquidated damages, defects liability, periods, intellectual property, interface agreements and financial projections/guarantees prior to signing contracts Funding High capital costs for Waste-to-Energy plant Construction costs based on specific time period, if completion is delayed, damages may accumulate Understanding Risks

15 Proprietary Information Of Energy 2013 Increased energy security and energy savings May allow installation to increase and change mission objectives, diverting energy spend for other uses Prestige associated with achievement of energy goals Plants are eligible for REC credits that may be sold to other energy users to offset carbon footprint and provide additional funding for the installation As technologies are used and refined, the next generation becomes less expensive and more efficient Earning Rewards

16 Proprietary Information Of Energy 2013 Market Look for projects with financial incentives, skilled workforces, adequate transmission and abundant input source Project Team Create a team with decision makers, compliance officers, financial experts and appropriate engineering staff Find common goals and determine generation misconceptions early to prevent unnecessary roadblocks during negotiations Lessons Learned

17 Proprietary Information Of Energy 2013 Project Schedule Projects that are shovel ready can better adapt to changing conditions Understand the environmental regulations required prior to committing to a schedule, certain studies can only be performed during specific intervals within the year Site Considerations Clearly defining the level of priority for project development and creating master site and energy plans can help resolve any land-use conflicts existing at potential sites Lessons Learned

18 Proprietary Information Of Energy 2013 Utility Regulations as Barriers Interconnection, net-metering O&M is Key for Success Improper maintenance reduces system efficiency and threatens the useful life of equipment. Training Required interval training and proper documentation Feedstock management Lessons Learned

19 Proprietary Information Of Energy 2013 Questions?
