  1. Combined Heat & Power Workshop Columbus, OH -- June 20, 2012

  2. Who we are…… • Largest independent producer of metallurgical coke in the Americas. • Five facilities in United States • Vansant, VA (Jewell) • Indiana Harbor, IN • Haverhill, OH • Granite City, IL • Middletown, OH • One Facility in Brazil • Vitoria, Santos Espirito • Over 5 million tons/year of coke capacity • We also mine coal via multiple mines in VA.

  3. Our Facilities Domestic Operations International Operations SunCoke Energy Headquarters Lisle, IL Indiana Harbor268 Ovens Capacity: 1,220kt Steam: 1,000klbs/hr Middletown (2011)100 Ovens Capacity: 550kt Power: net 48 MW Haverhill (2005, 2008) 200 OvensCapacity: 1,100kt Steam: 450klb/hr Power: net 46 MW Brazil Granite City (2009)120 Ovens Capacity: 650kt Steam: 450klbs/hr Jewell Coke142 Ovens Capacity: 720kt Vitória(1) (2007) 320 Ovens Capacity: 1,700kt Power: 150 MW (1) SunCoke holds a preferred interest in Vitória and is the operator.

  4. SunCoke Energy Process

  5. What is Coke? • Metallurgical coke is an integral part in the manufacture of steel. • Coke has four important jobs within a blast furnace: • Provide support (Layers of iron ore, limestone, coke, etc.) • Provide heat (Coke combusts within the furnace) • Provide carbon (reactions for making of the steel) • Provide Permeability (to allow air flow and liquid flow) • Manufacture of steel has always looked for these properties. • Back in the early 1800’s, charcoal provided these needs • As furnaces grew in capacity (and size) charcoal was not adequate so the industry turned to coke.

  6. What is Coke? (cont.) • Metallurgical-grade coal is mined, washed and sent to coke facilities. • Coal is further crushed to very small particle sizes (1/8” or less) in preparation for charging into a hot coke oven. • Coal is charged into a hot oven to be converted to coke. Sometimes termed as carbonization. • Coal over a period of time within the hot confines of a coke oven goes through several transformations as the thermal temperature wave moves through the bed: • Forms a plastic layer that serves to agglomerate the small particles. • Evolves tars and hydrocarbons (Volatile Matter) • The plastic agglomerated mass solidifies into large pieces • Stabilization of the coke into the solid product

  7. Coke Making • Has been made for centuries • Originally just mounds of coal, sometimes with dirt over the mounds to hold in heat (much like some manufacture of charcoal) • Utilized beehive ovens (so named due to internal shape) which were crude heat recovery. • Were the predominate type for decades in Pennsylvania, West Virginia, Alabama, Tennessee. Several thousands of these ovens were built and operated. • Recovered heat for the coking process, but the waste heat, along with pollutants was sent directly to atmosphere. • Slot ovens for byproduct recovery. Still the way the majority of coke is made worldwide. • Heat Recovery with waste heat utilization (SunCoke).

  19. Haverhill Operations HH1 (2005) HH2 (2008) HRSG Units (5) STG Building FGD System

  20. Haverhill 2 Interconnection - PJM • Studies – Total 3 • Feasibility Study • System Impact Study (SIS) • Facility Study • Process Length before construction • Approximately 30 months • Cost for project studied at 67 MW • Total Interconnection Study Cost: $213K (plus Letter Of Credit of $12M) • Revenue Potential • Energy and Capacity Resource

  21. Middletown Operations STG Building FGD System HRSG Units (5)

  22. Middletown Interconnection - MISO Studies – total 3 Feasibility Study System Impact Study (SIS) Definitive Planning Phase (DPP) Process Length before construction Approximately 24 months Cost for project studied at 67 MW Total Interconnection Study Cost: $280K (plus Letter Of Credit of $500K) Revenue Potential Energy Resource only

  23. Haverhill/Middletown Comparisions • Both utilize the same STG system. • Middletown’s economizer units are more advanced resulting in ability to capture more power. • Middletown is capped at 50MW maximum. • Haverhill transmits all of its generated power to AEP. Internal power is brought in on a separate feeder line. • Middletown consumes generated power for internal use and send the rest to Duke Energy.

  24. SunCoke Energy & PJM • All control room operators are educated and certified with PJM. • Initial Briefing Seminar • Generation 101 (& Test) • Generation 201 (& Test) • Generation 301 (& Test) • Operations 101 (& Test) • Closed book final exam • Middletown with the migration from MISO to PJM is deep into the certification process. • December 2012 completion • Each site has a lead for PJM. Normally the STG Area Manager. • Corporate contacts for PJM.

  25. Relationship Comparisons • PJM • Excellent relationship • Helpful during all phases • Follow up after project completion • Provide very detailed studies • MISO • Somewhat less involved with customer • Studies not as in depth • No longer involved since Duke has migrated to PJM

  26. Regulatory Filing and Reporting • Certification with Power Siting Commission of applicable state considers issues such as noise, visual impact, traffic, economic impacts and effects of the proposed facility on electric grid. • FERC (Federal Energy Regulatory Commission) • Certification as a “Qualifying Facility” provides the right to sell energy or capacity to a utility, the right to purchase certain services from utilities, and relief from certain regulatory burdens. • Market-Based Rate Authority gives permission to sale energy, capacity, and ancillary services in the market. • Electric Quarterly Reports summarize the sales contracts executed using your market-based rate authority and the transactions under those contracts. • Department of Energy (with The Energy Information Administration) • EIA-860 survey represents the status of plants and associated equipment at year end. • EIA-923 survey reports generation, fuel receipts, consumption, quality and cost.

  27. Questions?.........Thanks…. • Questions? • Thanks to: • Andrew Conway of PUCO • Dr. John Quanci, VP of Technology, SunCoke • LawanderBradley-Bey, Business Development, SunCoke • For more information on SunCoke Energy, please go to www.SunCoke.com
