• A Council Resolution to reinstate the Balfour Road Aquatic Complex (as
part of the 2001-2006 Capital Improvement Program) approved by City Council
on January 8, 2002 as CIP number 522-5202.
• A Professional Services Agreement with Water and Energy Management to
perform a Cost Feasibility Analysis, and design this project, was approved
by the City Council and was executed on February 26, 2002.
• City Council Approval of the purchase of the Tecogen 60 KW Co-Generator on
February 11, 2003.
This project is one component of the Aquatics Complex Capital Improvement
Program, CIP Project No. 522-5202.
A cost/benefit study was performed by Water and Energy Management to
quantify the economic, technical, and environmental aspects of co-generation
at the Aquatics Facility. He produced a report last March that recommended
this would be a very good means of lowering the annual utility costs
associated with the operation of the Brentwood Family Aquatics Complex. In
his report he estimated that the project could save an estimated $41,875
annually (at current energy costs). This translates to a simple payback of
2.9 years for our investment in this project.
Co-generation is the simultaneous production of electricity and thermal
energy (hot water) from a single energy source (natural gas). The study
focused on how to lower the electrical and pool heating, costs by installing
a 60 KW co-generation system to generate electricity while concurrently
making hot water that is used to heat the pools. This would reduce the
operation of the existing pool heaters and supply electricity for the pumps
and other electrical needs of the Aquatics Facility. The natural gas
purchased for running the co-generator is also half of the cost of our
current rate due to the fact that the PUC is encouraging the use of such
The current progress of this project:
• Cost Feasibility Report completed March 8, 2002.
• PG&E Generating Facility Interconnection Application filed and site visit
completed in June 2002.
• Public Notice from the Bay Area Air Quality Management District sent to
parents of the neighboring school site (Brentwood Elementary School). Public
Notice period was complete, with no comments from the public, and our
“Permit to Operate” was approved in January 2003.
• PG&E Self-Generation Incentive Program Grant applied for, and
conditionally approved (April 2003), for a minimum amount of $60,000.
• The design for the pool equipment plumbing modifications was complete in
May of 2003.
• The City has purchased, and has available to install (since August of
2003), the co-generator unit.
• The initial co-generator design, with current PG & E requested
modifications to the original design, was completed in October of 2003.

Therma Mechanical Contractors Late with bid (but was higher than above)
Rissi Mechanical No bid submitted
The lowest, responsible bid was received from Comfort Dynamics, Inc. in the
amount of $137,540.
Since this bid falls within the project construction budget of $144,032,
staff recommends authorizing the City Manager to execute the contract with
Comfort Dynamics, Inc., Inc. in the amount of $137,540.00. Including a 4%
construction contingency of $5,500, this brings the total project
construction cost to $143,040.
This project has a 30 calendar day construction period.
• A reduction of annual utility costs of $41,875 (this includes the purchase
of co-generator fuel and an outside maintenance agreement).
• There is $84,032 left in this CIP fund Project. Finance will loan this
project the additional money needed ($60,000) until the guaranteed minimum
PG & E grant ($60,000) is awarded to the City of Brentwood.
