Typical SunCoke Energy Battery • Coal specifications – Typical volatile matter is 21% to 28%, campaign 19% to 32% – Average reflectance range of 1.00 to 1.65 • Can generate steam or power – Approximately 9 MW / 100 kmt annual Run of Oven coke production – Annual power production of 788 kW-h / mt coke • No wastewater treatment plant required • Can be constructed on a new site or existing site (brownfield) • 48 hour cycle / 43.2 metric tons (48 short tons) coal • 1540C max temperature • Plant designed for 30 year run life • Approximately 2 – 4% Yield Loss • 2 – 5 CSR increase over By-product plant using same coals – Improved Strength attributed to slower heating rate, higher temperatures and longer soak time resulting in consistent crystal growth September 2011 SunCoke Energy 19
