5 Clean, renewable electricity Reduces greenhouse gas emissions Safe, reliable waste disposal Recover metal, preserves land and Ground water EfW Technology Dependence on fossil fuels Climate change Population growth Resource management Metal: 50 lbs Power: 550 kWh Ash: 10% of original volume Inert - no methane generation Municipal Solid Waste (MSW): 2000 lbs EfW is a specially designed energy generation facility that uses household waste as fuel and helps solve some of societys big challenges
6 Industry Overview of Energy from Waste US EPA -- EFW disposes of 13% of the nations waste 89 facilities 29 million tons per year 36 million people served 27 states Generation capacity in excess of 2,700 MW 16 million MWhrs of renewable power generated annually
7 Proven, Utility Grade Technology Exclusive North American licensee for Martin GmbH Reverse Acting Stoker Grate technology – successfully processed more refuse worldwide than any other system available,
8 Floridas Renewable Generation Capacity is Quite Low *Includes 1080.7 MW Renewable Energy Generation Source: FL PSC Current FL generation Capacity 51,569 MW Current FL renewable generation Capacity 1,081 MW or 2% of the states capacity
9 The Power of EFW in Florida One ton of MSW Has the energy equivalent of One barrel of fossil fuel oil or 10 MCF of natural gas! EFW is a proven source of Florida renewable energy Annually Floridians generate 31.2 million tons of MSW which is the energy equivalent of 31.2 million barrels of oil. Currently 6.5 million tons (17,900 tons per day) of MSW can be processed annually by Floridas 12 EFW Facilities. This eliminates the need for 6.5 million barrels of oil or 65 million MCF of natural gas. 506 MW of renewable electrical energy is generated on a daily basis by Floridas EFW Facilities Saving annually over 8,125 acre feet of precious landfill space through volume reduction.
10 The Environmental Benefits of EFW Produces renewable electricity with less environmental impact than almost any other source of electricity US EPA April 14, 2003 Provides a net reduction in Green House Gas Emissions (GHG) Displaces CO2 (GHG eqv 1) that would otherwise be generated as a result of producing electricity from other fossil fuels sources Eliminates the release of uncollectible Methane (GHG eqv 21) from raw Municipal Solid Waste Landfills Recycling of the Ferrous and Non-ferrous metals recovered following the EFW process avoids the GHG emissions that would be associated with the smelting of virgin ores
11 More EFW is Being Done… By 2010, Renewable Energy from Florida EFW is planned to increase by 85 MW: Lee County20 MW Hillsborough County17 MW Palm Beach County 28 MW Pasco County20 MW Bringing to 591 MW the EFW Renewable Energy made available while processing less than 25% of the Florida MSW being generated.
12 More EFW Can Still Be Done… Over 18 million tons of raw MSW is still being landfilled every year in Florida. EFW Technology can convert this waste into approximately 1130 MW of new Renewable Energy A significant number of highly developed areas of the State still heavily dependent on land filling raw MSW as their primary method of solid waste management. Orange County 1,820,638 TPY Duval County1,483,456 TPY Brevard County 704,476 TPY Volusia County 499,242 TPY Collier County 477,095 TPY Manatee County 343,095 TPY Seminole County 303,015 TPY Sarasota County 297,421 TPY Developing new EFW capacity to manage the nearly 6 million tons of MSW available from these areas alone would increase the States Renewable Energy generation by approximately 372 MW while increasing our energy independence by the equivalent of approximately 6 million barrels of oil each year. This will only be possible with the right incentives
13 Encouraging Florida Renewables Current Situation 63% of Floridas electrical generation is fueled by oil and gas Low energy payment rates and contracting structures that have been offered since the early 1990s for new EFW capacity inhibited further development Florida has no functional wholesale electricity markets to support EFW or other renewable energy development; local utilities are the only buyers
14 Encouraging Florida Renewables The Future 81% of Florida capacity additions are currently proposed to be fueled by oil and natural gas Renewables including EFW must be a part of changing this future Executive Order 07-127 signed by Governor Crist at the Climate Change Conference limits allowable GHG for electric utilities Executive Order 07-127 requires utilities to produce substantial additional amounts of electricity from renewable sources
15 Encouraging Florida Renewables The Future (Continued) Recent Supreme Court Ruling United Haulers Association Inc. vs. Oneida-Herkimer affecting the landmark 1994 flow- control decision in C&A Carbone vs Clarkstown New (and renewed) EFW contracted energy generation must be valued based on avoiding the most expensive fossil fuels Development of a functional and liquid wholesale electricity and renewable credit trading markets will stimulate growth Long-Term fairly priced energy contracts will encourage new project financing Encourage/require Renewable Portfolio Standard (RPS) to encourage the development of new renewable energy generation in the state
16 Renewables Portfolio Standards State Goal PA: 18%¹ by 2020 NJ: 22.5% by 2021 CT: 23% by 2020 MA: 4% by 2009 + 1% annual increase WI: requirement varies by utility; 10% by 2015 goal IA: 105 MW MN: 25% by 2025 (Xcel: 30% by 2020) TX: 5,880 MW by 2015 *NM: 20% by 2020 (IOUs) 10% by 2020 (co-ops) AZ: 15% by 2025 CA: 20% by 2010 NV: 20% by 2015 ME: 30% by 2000 10% by 2017 goal - new RE State RPS Minimum solar or customer-sited RE requirement * Increased credit for solar or customer-sited RE ¹PA: 8% Tier I / 10% Tier II (includes non-renewables); SWH is a Tier II resource HI: 20% by 2020 RI: 15% by 2020 CO: 20% by 2020 (IOUs) *10% by 2020 (co-ops & large munis ) DC: 11% by 2022 DSIRE: www.dsireusa.org June 2007 NY: 24% by 2013 MT: 15% by 2015 *DE: 10% by 2019 IL: 8% by 2013 VT: RE meets load growth by 2012 Solar water heating (SWH) eligible *WA: 15% by 2020 MD: 9.5% in 2022 NH: 23.8% in 2025 OR: 25% by 2025 (large utilities) 5% - 10% by 2025 for smaller utilities *VA: 12% by 2022 MO: 11% by 2020
17 EFW: A Proven Component of Floridas Renewable Energy Future Florida (+ 22 other states and Washington DC) define EFW as Renewable Energy To date 12 states and Washington DC define EFW as eligible for Renewable Portfolio Standards Efficiently recovers/exports over 550 KWhrs/per ton of MSW processed EFW is clean - Exceeds requirements of the Clean Air Act – US EPA Most advanced pollution controls of any energy generation source Reduces landfill requirements in excess of 90% Eliminates the release of toxic emissions and GHGs (especially methane) from raw waste landfills EFW and recycling are compatible: Recycling rate of EFW communities exceeds the national average by over 5%
18 Key Elements of a Successful Renewable Portfolio Standard Establishes clear annual targets that must be met by any load serving entity selling electricity to end-users in the state (private, public, munis, etc.) Ensures aggressive targets to foster renewable energy innovation and development Clearly defines qualifying technologies/fuels Allows markets to foster technology development without favoring specific technologies or fuels Allows Renewable Energy Certificate (REC) trading as separate product from traditional capacity, energy, and ancillary service produced by a generator Establishes independently operated entity to operate trading markets and monitor/verify REC generation, use, and load serving entity compliance Contains compliance, enforcement, and penalty provisions Defines Alternative Compliance Payment (ACP) in the $50 to $80/MWh range to be paid by any load serving entity that does not meet the RPS annual target Uses the funds generated by the ACP to support renewable generation R&D and energy efficiency programs
19 Florida has a beautiful precious environment that needs to be protected. This should be our issue Gov. Charlie Crist
21 Covanta Energy Corporation The 32 EFW facilities Covanta operates: Dispose of nearly 5% of nations waste Process about 15 million tons Produce about 1,200 megawatts of clean, renewable energy. Generate nearly 10% of the Nations Non-Hydro Renewable Energy In Florida, Covanta operates: 4 EFW facilities: Pasco County, FL Hillsborough County, FL Lee County, FL Lake County, FL These facilities: Process over 1.25 million tons per year of MSW Generate about 114.5 megawatts per hour
22 EFW Energy is Renewable Energy Municipal Solid Waste (MSW) is a sustainable resource for local power MSW is biomass. EFW efficiently converts energy value of MSW to electricity and/or steam EFW contributes to fuel diversity EFW facilities are located near power users, increasing cost efficiency. EFW avoids vehicle fuel consumption/emissions associated with increasingly distant transportation to landfills. EFW avoids landfill greenhouse gases and toxic emissions
23 EFW: A Success Story Upgrading of the emissions control systems of large combustors to exceed the requirements of the Clean Air Act Section 129 standards is an impressive accomplishment. The completion of retrofits of the large combustion units enables us to continue to rely on municipal solid waste as a clean, reliable, renewable source of energy. With the capacity to handle approximately 15 percent of the waste generated in the US, these plants produce 2,800 megawatts of electricity with less environmental impact than almost any other source of electricity. -- letter to IWSA from Assistant Administrators Jeff Holmstead and Marianne Horinko, US EPA February 2003
