FIN I NAME: Turbine Waste Heat Recovery
very
FIJI DESCRIPTION:
This improvement measure will result in the ren vationlinstallation of two existing 1000 hp Foots aeration
blowers that will be powered by steam turbines. Stearn will be generated by the Heat Recovery Stearn Generator
HFS that is powered by combustion turbine exhaust as conditioned by a duct burner fueled with digester and/or
landfill gas.
GOALS:
0 Reduce the number of electrical blowers required to run the aeration system
0 Optimize combustion gas turbine waste heat recovery
• Provide an energy conversion source for two new steam blowers
• Improve overall efficiency of combustion gas turbine
• Eliminate or reduce flaring of beneficial digester and landfill gas
• Electrical power savings through reduction of total electrical blower horsepower
ASSUMPTIONS:
• The waste heat recovery improvement measure was developed with the premise that all electrical power
generated by the combustion turbines would be used on site to prevent exporting of power, This is consistent
with the current operating procedures.
• From October 2007 to September 2008, the plant purchased 43.0 million k Wh of electricity, During that same
time, the plant generated 36.7 million kWh of electricity, resulting in a total plant electrical load of 79.7 million
kWh. If a second D T were operated at the plant, after energy conservation is implemented, the T's would
typically generate more electricity than is required to operate the facility.
9 Engineering analysis performed to assess the additional volume of digester gas that will be produced by the
implementation of Anaerobic Do-Digestion (FIM #3A) and Digester Mixing upgrades (FIM #313) estimates a
0% increase in digester gas production. This increase in digester gas production, or an increase in landfill
gas, is required to operate both steam driven blowers and achieve full cost benefits of this FIM1.
• The site contains two 2 Roots Model H-30 aeration blowers, each rated at 31,000 scfm at 7.5 psig discharge.
To achieve this performance, the blower would need a driver rated at 1,144 horsepower and turning 5}600 rpm.
Refitting these blowers with turbine drivers and placing them online will supplement the aeration blower
capacity at the pillage Creek ' 1fIfI~P.
Landfill gas will continue to be supplied to the pillage Creek V' 1fIfI~P.
All construction work will be accomplished in stages to accommodate operation of existing facilities during
construction period.
Only one of two existing CGT's will be out of service at any given time.
FINAL ENGINEERING:
INN:
• Development of construction drawings and equipment submittals.
• Finalize equipment performance requirements.

The tank structure shall conform to the design requirements of AIJA standard for Welded Steel Tanks for
Water Storage,A WA Standard D 100-96.
• Concrete roadway and curbs.
• Concrete tank foundations and walls for partial containment of spills,
Grinder.
• Recirculation/transfer chopper pump 1 with appurtenances} piping, valves and heat exchangers for each
batch tangy (2). This pump will be used to circulate and mix the contents in each of the two batch tanks. By
manually switching the discharge valves, the pump will transfer the contents of its tank to the suction line of the
mix tank recirculation pumps. There will be a transfer line between the suction of the two pumps so that either
could be used to pump out the contents of the opposite tank if necessary. This pump will operate only in
manual on off mode, with low-level shutoff from the appropriate tank's ultrasonic level sensor (interlocked with
the pump in use for that tangy . A simple heat exchanger on the discharge of each pump will be controlled by a
temperature sensor in the discharge line. If the recirculation pump is operating and the wastewater is below the
operator-specified setpoint, the controller will open the solenoid valve in the hot water supply to the heat
exchanger and turn on the hot water booster pump. Once the temperature exceeds the setpoint, the controller
will close the solenoid valve and turn off the pump unless the other heat exchanger or the room heater is calling
for it to be running. In the event of a high amp draw, the recirculation pumps will shut down on their own and
an alarm will sound.
• Recirculation chopper pumps 2 with appurtenances, piping, valves, and Rota-Mix nozzles for mix tank. These
pumps (one duty, one standby) will be used to circulate and mix the contents of the large mix tank, discharging
into the l otamix distribution nozzles. These pumps will operate only in manual on/off mode: with low-level
shutoff from the mix tank's ultrasonic level sensor.
0 Feed chopper pumps 2r piping, valves, and flow meter to transfer mix tank contents to digester manifold.
These pumps (one duty, one standby) will be used to transfer the contents of the mix tank to digesters 9-14.
These pumps will alternate operating in 10-minutes cycles as follows:
The motor-operated feed valve for digester#9 will open, feed pump A will turn on and pump an operator-
specified volume of wastewater to the digester, taking several minutes. When the pumped volume,
measured by the manifold flowmeter and totalizer, reaches the setpoint, the pump will shut off and the
digester feed valve will close.
The motor-operated feed valve for digester#10 will open, feed pump B will turn on and pump an operator-
specified volume of wastewater to the digester, taping several minutes. When the pumped volume,
measured by the manifold flowmeter and totalizer, reaches the setpoint, the pump will shut off and the
digester feed valve will close.
The cycles will continue from digester to digester, making a complete circuit in one hour.
Operation will alternate between pump A and pump B.
In case a pump turns on and a digester feed valve fails to open, a high pressure sensor will alarm. If the
pressure continues to rise after the high pressure alarm has sounded: then a pressure relief valve in the
feed line will open and dump wastewater back to the mix tank.
• Hot water supply/return piping and booster pump to provide hot water to batch tank heat exchangers and room
heater.
• Installation of approximately 750-feet of -inch PVC scum transfer line and in-line grinder. The enact routing of
the scum line has not yet been determined. There is a possibility that and unused pipe using could be utilized
during the installation of this line.
0 Installation of approximately 200-feet of -inch PVC thickened WAS line. The enact routing of this WAS line has
not yet been determined. It appears that the pipe gallery will not be able to be used.
0 The installation of all electrical equipment shall be done in conformance with latest national electrical code.
Equipment shall be sized and installed per manufacturers' recommendations. The project includes modification
to MCC bucket, feeder conduit and conductors. Also, a 480V distribution panel, combination motor starter

MEASURED SPECIFIC PERFORMANCE E UARANT (NIBP ) PROJECT BENEFITS
In a Measured Specific Performance Guarantee IISP , the determination of Project Benefits is based upon the
differences between Pre-Retrofit and Post-Retrofit equipment and/or operation. The Ivey performance factors that
impact the performance of pre-retrofit and post-retrofit equipment and/or operation are defined relative to each
measure and are shown in this Exhibit. Certain key performance factors require a physical inspection and/or
measurement prior to and after project completion. The pre-retrofit factors and those requiring post-retrofit
inspection and/or measurement are identified as such in this Exhibit. These factors, the method of determination of
post-retrofit factors, and the equations necessary to determine Project Benefits is mutually agreed upon by
approval of this Performance Contract.
o uti n B
Retrofit Isolation
Measured Project Benefits are determined by field measurement of the energy use of the systems to which an
Improvement Measure was applied separate from the energy use of the rest of the facility. Short-term, long-term or
continuous measurements are taken throughout the pre-retrofit and post-retrofit periods. Engineering calculations
which include the pre-retrofit and post-retrofit measurements are used to calculate the Measured Project Benefits
for the duration of the Guarantee Term,

Baseline Model
The City of Fort forth did not begin recording the amount of power consumed by the aeration blowers (using the
E Genius power monitoring system) until the end of 2008. Since the baseline period is October 2007 to
September 2008: there was no record with which to establish a measured baseline for aeration blower energy.
With the agreement of the City, a Baseline Model was developed and used to determine the baseline power
consumption for the aeration blowers. Plant drawings, O&M manuals, actual monthly plant operating records(base
year) and measurements were utilized to develop the Excel-based computer model. The Baseline Model was also
used to calculate annual energy savings for I~lMs #2.5 and #5.5. Figure 1 provides a logic fiow diagram for the
structure of the Baseline Model.

If any basins that were not in service during the Performance Contract base years (such as Basins 12S and 13N
are put back into service in the future, monthly operating data and the Baseline Model will be utilized to calculate
baseline adjustments.
FIM#3A.5—Anaerobic Co-Digestion
FIM#3B.5—Digester Mixing Upgrades
The savings will FINS #3A.5 and 38.5 will be realized from an increase in generated kWh from the two existing
combustion gas turbines. These improvement measures will increase digester gas production and allow the plant
staff to operate one of the two combustion gas turbines at full output capacity year round. Also, FIM #3A.5 and
38.5 rust be implemented to achieve full cost savings for FINS#2.5.
Pre-Retrofit:
• Annual baseline turbine-generated kWh was measured by the existing turbine sub-meters.
Post-Retrofit:
• Annual post-retrofit turbine-generated kWh will be measured using the same existing turbine sub-meters for the
duration of the Guarantee term.
• New equipment associated with these improvement measures will impact the total energy savings. The
parasitic kWh savings of the new equipment will be stipulated. Refer to Exhibit 4 of this schedule for detailed
calculations of the parasitic kWh h savings.
For all improvement measures, other baseline adjustments may be necessary due to future plant upgrades, permit
requirements and reprised plant operation procedures.
There must be mutual agreement between the City and JI before baseline adjustments are determined to be
conclusive.

FIM#3A.5-Anaerobic -Digestion O&M Cost Avoidance
There will be a reduction in the volume of solids produced and a resulting reduction in the cost of solids disposal.
Additionally, the current operation of the scum incinerator will be eliminated, If the City chooses to operate the
scum incinerator, it will not void this Agreement, however, it will reduce the realized O&M savings for the City.
There will also be a new facility O&M expense resulting from the operation of the codigestion drop-off station.
The total expected O&M savings for implementation of Co-Digestion is 3,7 5/yr.
Solids Dig al Savings
Village Creels Wastewater Treatment plant currently disposes 25,378,052 lbs of volatile solids per gear. This
represents a volatile solid reduction rate 41.04% in the digesters. It is estimated that the good mixing resulting from
Filly 3B.5 will improve the volatile solid reduction rate to 44.3%. When codige tion is added to the process, the
volatile solid reduction rate is expected to reach 45.3%. This additional reduction will provide a reduction of 212
tons of volatile solids produced.
Scum Incinerator Savings
Currently, each of the two incinerators mast be relined, and the burner nozzles replaced once every five gears at a
cost of$130,000 per incinerator. This cost can be a nnuali ed to a cost of 52,00 O/yr in incinerator maintenance.

If the Power Factor of Retail Customer's load is found to be less than % lagging as measured at the Meter,
Company may require Retail Customer to arrange for the installation of appropriate equipment on Retail
Customer's side of the Meter necessary to correct Retail Customer's Power Factor between unity and %
lagging as measured at Meter, or, if Retail Customer fails to correct its Power Factor consistent with this
standard, the demand associated with Retail Customer°s use of Delivery Service, as determined in the
appropriate Rate Schedules in Section 6.1 RATE SCHEDULES, may be increased according to the following
formulas:

POST-RETROFIT CONDITIONS
It is understood that the City will make decisions regarding operation of the plant to meet the conditions of the
discharge permit and that the City seeks to modify certain nodes of operation to improve wastewater treatment and
energy efficiency.
POST-RETROFIT OFIT TU BINE WASTE MEAT RECOVERY,t ANAEROBIC Do-DIGESTION & DIGESTER MIXING
OPERATING REQUIREMENTS
Post-Retrofit Anaerobic Co-Digestion Process o eratin
The feeding of the anaerobic digesters will be maintained in the current configuration. The feed to Digesters
through 14 will be maintained with a feed of thickened primary and activated sludges to maintain the same volatile
solids loading to the digester as a unit (not volumetric loading). It is anticipated that additional volume will be
gained by the cleaning of the digesters, providing longer detention time, more complete breakdown of volatile
solids, and improved gas production. It is recommended that Digesters 9 through 14 remain in operation year-
around and no more than one 1 of these digesters be removed from operation at any given time.
Volume and quantity of wastewater feed sludge processed in digesters 9 through 14 shall remain at current levels.
Post-Retrofit fit Hlah Strength waste Receiving Station operation
The City shall maintain a program of receiving high strength waste and feeding it to Digesters 9 through 14. The
City will identify potential industrial sources, and work with the owners, to make arrangements to receive high
strength wastes in sufficient quantities to provide the volume of gas production needed to generate sufficient steam
to maintain operation of the two proposed steam turbines.
The city shall provide minimum Co-Digestion loading of 125,000 lb/day of (COD) chemical oxygen demand.
Required actual volume of waste material shall Crary depending on strength of waste material.
All wastewater treatment plant scum shall be diverted to new co-digestion waste receiving station.
A small side stream of Thickened Waste Activated Sludge TI AS shall be diverted to the codigestion process.
The TWAS will be used to resolve possible quaternary ammonium saniti r quats toxicity in the dissolved air
flotation (DAF) float received from food processing industries. (note; as opposed to the dissolved air flotation
thickeners that are part of the wastewater treatment plant process),
If a proposed source of high strength waste is no longer available, the City will seek a new source of material so as
to maintain the level of organic loading to anaerobic digesters g through 14.
City personnel will operate the high strength waste receiving station, coordinating deliveries and assuring that the
material is suitable for co-digestion. City personnel will control the blending and feed operations to maintain the
desired level of organic loading. City will be responsible for maintaining the facilities in good wording condition.
Post-Retrofit Digester Mixinq operation
It is recommended that LMM's serving Digesters 9 through 14 remain in operation year-around and that no more
than one 1 of the LIMM's be removed from operation at any given tire,
Post-Retrofit Combustion Turbine Ogeration
The existing combustion turbines and associated generators will be operated so as to maximize the generation of
power from the single unit that is in operation. Maximum operating capacity of the turbines is to be maintained at
the levels described in Table 5 of Exhibit 6 relative to inlet air temperature. City is to continue use of the current
inlet air evaporative doling system in order to keep turbine inlet temperatures as low as possible.
Minimum uptime of 98% for one of the two existing combustion turbines shall be maintained year-around.

Post-Retrofit Heat Recovery Steam Generator and Duct Burner Overation
Under normal operating conditions, all exhaust gasses from the combustion turbine will be directed to the proposed
heat recovery steam generator (HR SG). Sufficient supplemental gas shall be supplied to the duct burner to
generate the steam required to operate two steam turbine driven aeration blowers at full capacity. Digesters will be
required to generate the minimum monthly gas amounts shown in the following Table 1,

DISCUSSION:
On September 2, 2003, (M&C C-19739)the City Council authorized an Energy Savings Performance
Contract, Phase i with.Johnson Controls, Inc. Subsequently, ESPC Phases fl, Ill and IV were approved
respectively by Amendment kilos. 1, 2, and 3.
On September 23, 2008, (M&C C-23046) the City Council authorized a contract with Johnson Controls,
Inc.,, ,JCI to conduct a detailed energy study of the Village Creek Wastewater Treatment Plant WWTP
as Phase V of the successful Energy Savings Performance Contract ESPC Project. The study is
complete and the product of this study, the Utility Assessment Report(UAR),, dated November 2009, has
been reviewed and approved by City staff. Kinsman and Associates Engineering Consultants retained by
the City as an independent third-party reviewer IIC C-23788), has reviewed the report and verified that
the project oasts, guaranteed savings, and measurement&verification rnedi ds are appropriate.
On February 02, 201 Os (M&C C-24070)the City Council authorized Amendment Igo. 4 to the City's ESPC

an agreement to Implement the ESPC Phase V, Section 2 project at the Village Creek WWrP.
The proposed ESPC Phase V, Section 2 scope of work includes energy-and operations-related
conservation measures and treatment process facility improvement measures to be installed at the Village
Creak WTP. The recommended measures include Turbine Waste-Heat Recovery,r, Anaerobic Co-
Digestion, Digester dicing Upgrades and Aeration Anoxic Zones.
The total ,JCI contract amount for Phase V, Section 2 is 1 7,889,397.00. This amount includes
$2,600,000.00 for Final Engineering and Construction Management, which will be funded through existing
Sewer Capital Projects Fund appropnations. Auer implementation of the Improvements included in Section
2. the first-year electricity savings are estimated to be $1,528,971.00. Including other cost avoidance, the
simple payback period is about 11 years. While more than the 1 -year payment tenet desired, City staff
and its third-party reviewer deem it reasonable and appropriate for the scope of work included, and well
within the 0-gear limit set in the applicable Texas state law.
In accordance with the City's a isOng ESPC and as allowed by Texas Local Government Code Chapter
302, .JCI published a Request for Bid fbr a Municipal Equipment lease-Purchase (Municipal Lease)

the recommended Municipal lease financing agreement with ,JCI will utilize this financier resulting in a
total principal and interest cost to the City of$19,782,691.16 to fund the project construction including a
$76,000.00 underwriting fee. The annual appropriation for the Lease-Purchase payments will be included
in the operating budget requests for Water& Sewer and will be offset by electricity savings at the Village
Creek WWTP.
The recommended Escrow Agreement with ,JCI is a necessary attachment to the Municipal Lease,
allowing for progress payments to be made to,JCI during the construction phase of the recommended
project. The escrow bank associated with All American Investment Group, LLC AAIG is Deutsche Bank
National Trust Company. JCI will submit progress pay requests to the City for approval of contracted work
complete. City approved pay requests will then be submitted for payment directly from the escrow account
with Deutsche Bank rational Trust Company to JCI for the completed work.
As part of the recommended contract and in accordance with Chapter 302, ,JCI will guarantee projected
savings to the City and will perform on-going measurement and Verification services under an annually-
renewable Assured Performance Guarantee(APG) service agreement. As with all project costs, the cost
of the APGis included as an avoided cost to the City. ,JCI will also manage appropriate applications for
