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 System – Patrick 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
