10 The development of the CMM power project is being undertaken in three distinct sequential phases Feasibility Assessment Plant Design, Permitting and Interconnect Study Construction and Commissioning Understand mine power requirements and profile Assess gas availability, quality and volumes Determine potential technology solutions and applicability Estimate plant size and design based on gas availability, electricity demand and technology options Analyze the financial case for the power plant and determine success criteria Develop project structure and financing options Finalize plant design and operational characteristics Determine plant emissions profile and initiate permitting applications Undertake grid interconnect study to understand implications of introducing power to the grid Determine stand- by power requirements Negotiate off- take or tolling agreements Construct and commission plant according to finalized design specifications Ongoing operation and maintenance of the plant to meet availability and efficiency targets Expansion of the plant depending on the mine electricity needs and modularity of the technology solution 2010 CAR Workshop Morgantown, WV Unlocking Carbon Value. 10

11 Understanding the sources and sinks of energy was critical in conceptualizing the power plant Gas Supply Potential Generating Plant Capabilities Mine Power Demand Profile Analysis of mine methane in- situ reserves Determine drainage potential and CMM & CBM delineations based on mining plan and projections Build a gas supply profile with projections on volume and composition of supply Assess drilling and infrastructure requirements for gas supply e.g. compressions, gas treatment, piping Pre- technology selection Define plant generating characteristics based on gas supply and power demand analysis Post- technology selection Determine plant production characterizes and determine the potential for excess power sales to the grid or the need for supplemental grid power and backup/contingency provision Assess the need and implications of grid interconnect Identify power sources and sinks at mine facilities Build a mine power demand profile based on historic use and projections Assess possibility for shaping demand profile to better suit power generating plant capabilities or to avoid peak costs Daily power demand profile ILLUSTRATIVE Gas Composition Analysis ILLUSTRATIVE ILLUSTRATIVE Gas Production Volume Analysis ILLUSTRATIVE Equipment and Process Load Curves ILLUSTRATIVE 2010 CAR Workshop Morgantown, WV Unlocking Carbon Value. 11
