This workshop will cover the components of cogeneration in an attempt to answer the question of the feasibility of cogeneration. There will be an overview of the costs associated with procuring, operating, and maintaining a cogeneration facility through its lifecycle.

Included in the analysis will be a list of benefits and revenue streams that can be generated to cover some or all of the costs associated with running such a facility. Alternatives to cogeneration will be discussed as well.

The workshop will include a discussion of costs, revenues, and benefits for plant managers and decision makers to help determine if co-generation is right for your facility.

Learning Objectives: Factors and means that go into the decision of whether to implement cogeneration at your facility.

Who Should Attend? Plant staff, plant managers, municipal decision makers.

Organized by Joel Borchers POM Committee (Clean Water Services) and Christina Davenport (Resource Recovery Commitee (City of Bend) Moderated by Susan Hildreth, Residuals & Biosolids Committee (King County) and Christina Davenport.

Agenda and Presentations

9:00 – 9:15 Introduction

9:15 – 9:45 Turn up the Heat - Anthony Tartaglione, Black and Veatch "This presentation will benefit utility managers and operational staff by providing guidance on how to improve project efficiency. Alternatives considered to increase the hot water supply and performance are discussed along with capital and life cycle costs for each. The approach described in this paper capitalizes upon operational staff knowledge to potentially utilize and integrate existing systems in the design increasing efficiencies."

9:45 – 10:15 Lessons learned from Planning, Designing, Constructing and Commissioning Biogas-Fueled Cogeneration Systems – David L. Parry, Jacobs "Insights from different phases of the projects are given with regards to selection of cogeneration units, biogas treatment process, hydronic system design, and electrical interconnection."

10:15 – 10:30 break

10:30 – 11:00 Conversion of WWTP Digester Gas into Compressed Natural Gas Vehicle Fuel Jessica Bernardini, Cornerstone Environmental Group, A Tetra Tech Company Digester biogas upgrade to renewable natural gas, case studies

11:00 – 12:00 Cost of Operating and Maintaining a Cogeneration SystemPatrick Orr, Clean Water Services "A fully functioning cogeneration facility consists of many systems. Operating and maintaining each of the systems will have a cost associated with it. These costs will typically include labor, material or parts, and consumables. Developing a plan for operating and maintaining each system will allow for budgeting and labor requirements associated with a successful cogeneration facility."

12:00 – 1:00 lunch break

1:00 – 2:00 Valuing Carbon -Incentives for Beneficial Use of Digester Gas and Other Sustainable Projects - Steve Krugel, Brown and Caldwell "The presentation will discuss ways communities are adding value to carbon and other sustainable benefits into their traditional cost evaluations and how this may incentivize project development. Topics covered : carbon valuation approaches, including those based on cap and trade markets, the social cost of carbon and adopted values based strictly on community environmental ethic, and addition available direct monetary incentives for some uses such as Renewable Identification Number (RIN) credits."

2:00 – 3:00 A Presentation on the Cogen Project at Central Kitsap WWTP Peter Zemke, Brown and Caldwell "Central Kitsap WWTP provides an example of how cogeneration can be feasible for smaller municipalities. This presentation describes the performance and features of the plant’s 250-kW cogeneration system."

3:00 – 3:15 Break

3:15 - 4:15 Cogeneration feasibility study for Bend, Oregon - Jeremy Keller, Ameresco "A presentation on reducing the biogas monetization options to consider for your digester with an early focus on return on investment and risk transfer.”

4:15 - 4:30 Q&A and Wrap up

Brief Biography and/or Qualifications
Ms. Jessica Bernardini
Jessica is a Senior Project Manager with 12 years of experience in a range of solid waste and biogas utilization projects. Her most recent projects focus on the utilization of digester and landfill gas for renewable energy and natural gas in California and the Pacific Northwest. Jessica has provided engineering and permitting assistance to biogas utilization projects, prepared feasibility studies for initial analysis of project alternatives, and prepared and managed Federal and State grants and funding opportunities. Ms. Bernardini is a certified professional engineer in Oregon, Washington, California, and Alaska.

Anthony Tartaglione, P.E., BCEE
Anthony has contributed in the planning, execution, and successful completion of numerous projects through the creation of clear and attainable project objectives, developing project requirements, and managing the triple constraint - cost, schedule and quality over his 18-year career. As a process engineer, his experience includes alternative energy, thermal oxidation and thermal desorption systems, anaerobic digestion, sludge dewatering and thickening processes, pumping station design, applying mass and energy balance principles to optimize plant operations and assess future capacity needs, and executed hydraulic capacity and modeling studies.

From both engineering and management perspectives, Anthony has leveraged experience working with industry technology leaders to develop technical expertise and competency in project pre-planning, design, and constructability. He has learned the importance of effective communication in all forms and has embraced this tenet in everything he does. These qualities and experiences are reflected in his leadership skills, relationship building, and commitment to excellence and enthusiasm to create opportunities from challenges including nutrient removal and recognition of “wastewater” as “resource-water”.

Patrick Orr
Patrick is a Senior Engineer at Clean Water Services in Hillsboro OR where is has been since 2013. From 2009 to 2013 he was at Environmental Engineering Services. He received his Bachelor of Science (BS) in Mechanical Engineering from SUNY Buffalo.

Dave Parry
Dr. Parry is Senior Fellow Technologist at Jacobs Engineering. He has over 35 years of experience in the planning, design, and construction management of wastewater treatment, solids processing, and energy projects. He is actively involved on several wastewater, biosolids, and energy projects throughout the world. He earned his Ph.D. in mechanical engineering from the University of Illinois at Urbana-Champaign. He earned his Bachelor and Master’s degrees in mechanical engineering from Brigham Young University. He is a registered mechanical and civil engineer in several states and provinces in North America. Dave is a Board Certified Environmental Engineer (BCEE) with the American Academy of Environmental Engineers.

Peter Zemke
Peter received his Ph.D. from Utah State University in 2010, and is a Mechanical engineer at Brown and Caldwell, specializing in biogas conditioning and end uses, plant heating systems, blowers and aeration systems, microalgal cultivation, and energy systems.

Jeremy Keller
Jeremy Keller received his B.S. in Mechanical Engineering from the University of Washington in 2005 and his M.B.A form Oregon State University in 2007. He is a Project Developer for Ameresco where his responsibilities include (1) Initial field audits and identification of potential conservation measures, including supporting sales staff in initial client meetings; (2) Investment grade energy and resource conservation audits including project life financial forecasts. Includes logging equipment performance, analyzing trends, energy models, calculating baseline energy use and proposed retrofit scope/energy use; (3) Define IPMVP scope for post project measurement and verification of energy savings; (4) Manage small teams to package audits into construction projects including sub-contractors, and the customers staff.

He works with project managers to construct projects developed during the audit and holds the ultimate responsibility for the financial performance of multiple simultaneous multi-million dollar projects which pay for themselves with energy savings. The typical project includes lighting and water retrofits, HVAC upgrades/replacements, building controls modifications/replacements, envelope improvements and demand management. Typical customers: colleges, office buildings, warehouses, fire stations, K-12 schools, waste water treatment plants, and industrial sites. He is also responsible for building and implementing the NW region local tracking of projects, financial forecasting for integration with corporate systems and facilitated work load balancing between staff.
