1 Ohio Energy Workshop Q Maximizing Plant Efficiency with Waste Energy Recovery Options Tuesday, February 16, :15 p.m. to 4:30 p.m.

2 Biographical Information Lucas Dixon, CEM, Project Manager, Plug Smart 990 W. 3rd Ave., Columbus, OH Mr. Dixon is Chief of Strategy and a Project Manager for Plug Smart, an industry leading Energy Efficiency Company based in Columbus, Ohio. Mr. Dixon is proud to serve on the board of directors of Green Energy Ohio (GEO) and the American Solar Energy Society (ASES). Mr. Dixon enjoys creatively serving clients through rigorous engineering and creative financing solution. Mr. Dixon embodies Plug Smarts mentality of Running to Problems and the love of saving energy/money. Jarret Kelley, CEM, Senior Energy Engineer, Plug Smart 990 W. 3rd Ave., Columbus, OH jarret.kelley@plugsmart.com Mr. Kelley is Plug Smart s lead Energy Engineer. As a graduate of the Renewable and Clean Energy Master s program at the University of Dayton, Mr. Kelley has a broad background in renewable technologies and clean, efficient, and cost-effective energy solutions. His knowledge in energy efficient buildings and manufacturing has proven valuable in helping companies reduce their energy consumption and their bottom line. At University of Dayton, Mr. Kelley was a graduate assistant for the Department of Energy. In this position he helped develop a software design tool for use in heating and cooling dominated buildings. He also helped to identify appropriate and field-validated mathematical simulation models for energy components. Mr. Kelley is also proficient in the following software programs; AutoCAD, Inventor, Fortran, MatLab, ProEngineer, EES, RETScreen, equest, esim, TRNSYS, and TRNSED. Mr. Kelley has conducted extensive research in the geothermal energy field, especially with respect to hybrid solar-geothermal systems. He has experience in detailed simulation and optimization of these systems in both heating and cooling dominated climates. With this knowledge he has developed a design tool for optimizing hybrid and non-hybrid geothermal systems through funding from the Department of Energy. Mr. Kelley also has experience as a consultant in geothermal design as well as optimizing geothermal systems currently in place. A partial list of recent energy services clients include University of Cincinnati, University of Toledo, Wittenberg University, Ohio Northern University, Great Oaks Career Campus, Findlay City Schools, General Electric, Village of Granville, North Olmsted City Schools, Carrollton Exempted Village School District, City of Toledo, Columbus Metropolitan Library, Columbus Zoo, Ricart Automotive, Morton Salt, Crown Battery, and Naples Community Hospital. Mr. Kelley s energy services expertise includes geothermal systems, renewable energy, lighting systems/controls, building automation systems, air/water cooled heat pumps, cogeneration systems, boiler systems, chilled water systems, energy auditing, energy policy, HVAC, rebate administration, air quality and ventilation, heat recovery concepts, and retro-commissioning. Mr. Kelley holds his B.S. in Mechanical Engineering and a M.S. in Renewable and Clean Energy from The University of Dayton.

6 Gas/Steam Turbine Generators Divided Up Into 3 Large Categories Waste Heat Recovery Waste Heat or Fuel Source exists Co Generation Need for a consistent heat source and power pricing works. Process Augmentation/Improvement Specialty circumstance where a STG can replace current process and yield better results. Example PRV Valve Replacement with backpressure turbine. 4

7 Waste Energy Recovery Aka Bottom Cycle Opportunity requires alignment of the stars: High enough quality fuel or heat sources Consistent availability of source Need for power and/or steam. Stable time horizon, to recoup investment. 5

8 Waste Energy Recovery 6

9 Aka Topping Cycle Co-Generation Opportunity Requires, need for consistent amount of heat, year round. Absorption chiller, cooling need Process heat need Re heat/dehumidification need Water heating need Consistent demand for electricity 7

10 Co-Generation 8

11 Process Augmentation Opportunity Requires, close process collaboration and alignment. Opportunity often exists when a process change or addition occurs. Replace one operation with something that yields more. 1 for 1 needs to yield >1. Example: Extraction steam turbine reduces pressure for other need, generates electricity, and improves steam conditions in plant. Requires buy in from all affected parties. 9

12 Project Development What s the process to understand my potential? 1. Feasibility Study 1. Technical 2. Economics 3. Contracting 2. Financing 3. Contracting/Permitting 1. Air permit or no air permit 4. Construction 1. Used equipment or new 5. Maintenance/M&V 10

13 PRV Replacement Project Overview Previous PRV from 400psi to 165 psi Steam vented to atmosphere. Post Project MW nameplate Backpressure STG $413,910/yr in electricity generation $1.4 Million in rider exemption dollars. Less than 1 year simple payback. Higher temperature 165 psi steam for process use. 11

14 PRV Replacement Turbine Everything good starts with a strong foundation! 12

15 PRV Replacement Turbine Arrived safe and sound! 13

16 PRV Replacement Turbine She s a big baby! 14

17 PRV Replacement Turbine Sometimes the Oxy Acetylene is the correct tool for the job! 15
