Page 4 of 8
conditions, acts of God, acts of the public enemy, riot, war, unavailability of equipment or supplies, or supply
chain delays caused by any of the foregoing , then Energy Services Contractor shall provide written notice to
the Town of the existence, extent of, and reason for such delays, and an equitable adjustment in the Time
of the Contract shall be made as a result. If a delay is attributable to failure by Town to perform its obligations
under the Contract or failure to cooperate with Energy Services Contractor in the timely completion of the Work,
an equitable adjustment to Time and Price shall be made as a result.
14. Certificate of Substantial Completion. Upon Substantial Completion of any Phase of the Work, Town

completion, and failure by Town timely to execute a certificate of substantial completion shall not operate to
extend the date of Substantial Completion.
15. Town Use. Upon substantial completion or start of beneficial use, whichever occurs first, Town is
responsible for use, operation, and maintenance of all aspects of the Work and Services. Energy Services
Contractor shall not be responsible for improper use, operation, or maintenance of any aspect of the Work or
Services by Town or others at any time.
16. Warranty. Energy Services Contractor warrants that the Work will be of good quality and new; that the
Work will be free from defects not inherent in the quality required or permitted; and that the Work will conform
to this Contract. Energy Services Contractor warrants that the Work shall be free from defects in material and
workmanship arising from normal usage for a period of one ( 1 ) year from the date of substantial
completion, or start of beneficial use by Town, whichever is earlier. This warranty does not cover any improper
use, operation, or maintenance of any aspect of the Work, or if the Work has been abused, altered, or repaired by
the Town or third parties without supervision by or prior written approval from Energy Services Contractor, or if
serial numbers or warranty date decals have been removed or altered. Town must report any warranty claims to
Energy Services Contractor in writing, and such claims must be presented immediately upon having reason to
know that a warranty issue exists. Failure by Town to notify Energy Services Contractor of the need for
warranty service within ten days of discovery of a warranty claim will void this warranty. Additionally, Town
shall not hire or direct others to repair any warranty item without Energy Services Contractor’s written consent.
Town’s repair of any warranty item without the written consent of Energy Services Contractor shall void this
warranty with respect to such item, and the cost of such repair shall not be reimbursable to Town by Energy
Services Contractor. Energy Services Contractor makes no warranty whatsoever regarding materials or products
provided by third parties that are incorporated into the Work. THE WARRANTIES CONTAINED IN THIS
CONTRACT ARE EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES, WHETHER EXPRESS,

Town Council meeting. This BESS project includes a Delta Power System 125kW power
conditioning system, 310 kWh duration of Samsung CRD and UL9540 compliant batteries. The
resilience BESS system will be controlled by the Ageto ARC controller.
Project includes a utility service upgrade which will be located at the new equipment pad
adjacent to the existing generator as shown in the presentation from October 21, 2021. The AC
distribution cables for both the existing PV solar and generator will be routed to the new
switchgear. The existing service will become an 800 AMP subpanel fed from the new switchgear.
Existing utility conduits are assumed to become abandoned and are assumed to be utilized in
feeding the existing switchgear from the new main switchgear.
As a part of the new service upgrade, it is assumed all existing utility conduits (3) will be used to
route utility distribution to the new switchgear. One (1) additional conduit is assumed to be
required to power the new switchgear. It is assumed there is room on the same side of the
underground vault to core through and add the additionally required conduit. The application
for the service upgrade is assumed to be completed by the Town’s electrical engineer, Pieter.

Introduction
SES has prepared the following report to evaluate microgrid options for the proposed
installation of a battery storage system at the Los Altos Hills Town Hall in Los Altos Hills,
CA. This resilience project is intended to provide backup power to the facility in the
event of grid outage as well as utility bill savings through Time-of-Use (TOU) shifting
when the grid is live.
The below analysis used assumptive inputs for the evaluation and makes assumptions
and estimates from the actual but limited site information. Actual outcomes may vary.
System Load Analysis
When the utility meter is the only device measuring the total facility power load and
the corresponding interval PV production data is not available, it is impossible to
calculate the exact load. This was the challenge at the town hall and one that often
arises with determining a proper power consumption profile for facilities with existing PV
when the PV is tied into the utility meter. The original PV Data Acquisition System from
the 2007 solar installation used password protected hardware, proprietary software,
and a remote database which has been abandoned for a number of years. The
actual historical interval PV production data was inaccessible. However, the town’s
third-party IT company captured screenshots of the annual production summaries from
a local kiosk for nearly a decade. This annual production summary was used in our
analysis. Due to this challenge, multiple methods of creating an accurate profile were
considered and attempted.
A synthetic PV profile was used based on the size, design and location of the existing
PV arrays, annual production and annual production summaries and adding that back
to the PG&E utility meter data. Because it is difficult to perfectly align 15-minute PV
production data with the actual production close enough to consistently arrive at the
actual total facility, there were enough obvious inaccuracies to make this method
inviable. Instead, a generic load profile was generated for a similar in small office
building located 8 miles from the town hall. This was scaled to meet the estimated daily
consumption of 345 kWh/day. The average daily energy consumption was calculated
with confidence by adding the known total yearly PV production and total yearly
energy consumption for 2019, then calculating the daily average. This generic profile
scaled to meet the true daily consumption is the load profile used for the modeling for
this report.
The following load profiles are DMaps (DataMaps) from our microgrid analysis tool
Page | 3
representing a year of power consumption. Time of day is located on the y-axis from 0
to 24, with noon in the center at 12. The x-axis shows the day of the year from 1 to 365,
starting with January on the left. Each 15-minute interval out of the year is represented
by a rectangle which is colored according to the data value for that hour. The power
scale in kW is located on the right. The DMap format often allows one to see daily and
seasonal patterns more easily than with a simple time series plot.
The below profile was generated using a combination of 15-minute 2019 utility data
pulled from the town hall’s PG&E utility meter #1009484321 (to which solar is tied in)
and a synthetic solar production profile from NREL (National Renewable Energy
Laboratory) added back in. This method likely provides a reasonable estimate of the
facility load, but contains some unavoidable inaccuracies, such as zero load in the
middle of the day (shown in black). Due to this, this profile was not used for modeling,
but to get insights into what it may have looked like.
Figure 1: Yearly Electrical Load from 2019
In the graph above there are instances when the load plus the solar are negative are
inaccurate (total facility consumption cannot be negative) and were given a value of
zero which are colored black. This graph is a result of not having actual PV data and
attempting to fold a PV model. It is an unreasonable assumption that the total load of
the facility was zero at any point, especially in the middle of the day. This model
cannot be used as days with “zero load” would have an effect on the battery sizing
and economic calculations. This load profile has an average energy usage of 304.5
kWh/day, an average power consumption of 12.69 kW, and a peak power load of
55.79 kW.
Page | 4
Figure 2: Scaled Generic Load Profile for a Small Office
Instead, a generic load profile for a small office building, pictured above, was used to
complete the analysis in this report. This load has an average energy usage of 350
kWh/day, an average power consumption of 14.58 kW, and a peak power load of
41.39 kW. 350 kWh was chosen based on the known total yearly consumption for 2019,
plus a cushion to be generally conservative. This profile provides a reasonable estimate
for the facilities consumption and aligns well with what can be interpolated from the
actual consumption data if the 15-minute PV data was available. The daily and yearly
energy consumption averages fall slightly higher for the scaled generic to compensate
for the “zero load” intervals in the production data profile.
The scaled generic load profile was used for the following analysis.
Microgrid Systems Analysis
The facility has existing solar arrays both on the roof and on the ground totaling 39
kWAC in capacity as well as a 65-kW emergency backup generator from 1993. The
generator is a dual fired generator with a natural gas line and propane tank. The
propane tank holds 500 gallons of stored fuel and if natural gas supply is not available
it will support the peak load for approximately 40 hours. In the current configuration
when an outage occurs the generator must work alone while the PV sits idle until the
utility power returns.
Page | 5
The scope of analysis includes the integration of battery energy storage solution and
microgrid control capabilities. The addition of storage will be utilized for power
resilience in the event of a grid outage and for electrical savings through TOU shifting
when the grid is live. The goal of this analysis is to demonstrate the ability of the
microgrid to sustain through a 72 hr., three-day Public Safety Power Shut-off (PSPS)
event running off renewables only, and energy bill savings when not in PSPS event. In
an emergency situation or prolonged outage, the solar and storage could operate in
tandem with the generator, if upgraded to allow for more advanced control
capabilities. The generator could operate indefinitely with an uninterrupted supply of
natural gas. If the gas line were severed in an emergency situation the facility could
run off of the generator's 500-gallon propane supply as long as it lasted. In the event
the gas line is cut, the generator alone could likely supply the facility with power for
over a month running off the stored propane. With aggressive energy conservation or
load shedding, the facility could sustain even longer.
In microgrids where grid services are performed, while resilience is still a priority, it is
advantageous to reserve a portion of the battery for unforeseen outages. This analysis
assumes that half of the available battery capacity will be reserved for outages. This
reserved portion can be easily adjusted at any time in the built system through the
microgrid controller. The portion reserved can be increased by the system operator
within the control user interface to be more conservative in case of an outage or
decreased to be more aggressive on grid services and utility bill savings. A “resilience
mode” can also be activated within the microgrid controller by the system operator at
any time to ignore grid services in order to prioritize charging the batteries with any
forewarning of an outage. Energy storage can be utilized to store excess energy
during the peak PV production hours which can then be discharged to offset peak
hours effectively meeting the goal of reduced cost of energy during the TOU periods.
Several different microgrid system configurations were modeled considering the current
use case of utility, solar and generator as well as the addition of two to four
Samsung/BYD battery racks at 170 kWh each and the addition of solar. The base case
to which the economics of other configurations were compared to is the current use
case of utility and solar.
Utility Tariff
The facility is on the PG&E’s B-6 Net Meter rate. The tariff does not include a base line
customer charge or demand charges. The rate does include TOU charges including a
summer peak, winter peak, off-peaks and a super off peak in the spring.
Page | 6
Below is a graphic visually displaying the energy consumption charges varying
throughout the year. The most expensive energy period is in the summer from 4 to 9 pm
when energy is $0.269/kWh.
Figure 3: Time-of-Use Energy Charges
Incentives/ Grants
No major tax incentives were modeled in this analysis under the assumption this project
will not be viable as this facility is a public (Town) building. The below table represents
grants and incentives the town currently and will possess in addition to the capital
match the two has made.

System Analysis
The analysis goal was to deliver resilience to the town hall within budget for a duration
of 72 hours by integrating multiple configurations of varying battery sizes with the existing
solar and generator. Two to four Delta Power Systems battery racks at 170 kWh each
paired with a 125 kW inverter were initially modeled. We then added an additional 20
Page | 7
or 40 kWAC of solar to the equation for consideration.
The below table demonstrates a few different options analyzed, each in conjunction
with the utility. The levelized cost of energy (LCOE) is a measure of the average net
present cost of electricity generation for a generating plant over its lifetime) was
considered which was found by dividing the total annualized cost of the system by the
total electric load served per year. Note, operating costs include the yearly amount
paid to the utility. A negative operating cost demonstrates more energy was sold to
the utility than consumed. These calculations are based on a 20-year life of the system.
The calculations are intended to represent the entire costs of design, engineering,
procurement, and construction of the system. It is assumed during normal daily usage
50% of the battery capacity will be reserved for outages.

The primary value of this solar plus energy storage renewable energy microgrid will be
derived from the power resilience it provides the Town. Additional value will be provided
through small savings on the monthly electric bill through Time-of-Use energy shifting.
There are no demand charges on this rate tariff, utility bill meaning all savings will be
derived from Time-of-Use shifting only. The largest swing of consumption charge is during
the summer peak which varies by only $0.10.

In a resilience configuration utilizing battery energy storage systems the financial
payback is realized over an extended period. The electric bill saving is due to the
specific rate structure of the utility tariff. The capital cost associated with the additional
battery capacity needed for resilience events is realized over the assumed extended
life of the battery serving demand reduction and TOU shifting. The value is in the reserve
capacity the battery storage possesses to support utility outages thereby allowing the
facility to continue to operate as if the utility had not dropped out. Serving the public, its
constituents as a COVID testing center, cooling center, and charging center during
these events is priceless. Therefore, there is an avoided cost of operational down time
as well as now being able to utilize the PV as an asset that would not otherwise be able
to be used with a generator. Additional solar would improves the overall payback of
the system providing more support to the charging of the stationery or future mobile
batteries during resilience events and for Net Energy Meter benefits.
The true value for batteries will be in power resilience. In the event of a grid outage such
as a Public Safety Power Shutoff (PSPS) event, the system will disconnect from the utility
and operate in islanded mode running off of solar and storage as conditions allow.
Solar inverters require a signal to grid follow. When the utility has an outage the utility
grid forming falls out. When in an islanded mode during an outage or a PSPS event the
ARC (Ageto) Microgrid Controller will command the battery energy storage to form the
grid allowing the PV solar to function as if the utility was forming the electrical grid. Solar
will both satisfy the building load and charge the batteries depending upon the time of
Page | 9
year, and daily weather. The battery will discharge to support the load as the sun goes
down and the solar production is reduced. When the battery storage charge is
reduced to a configured state of charge, the ARC (Ageto) Microgrid Controller will
open a contactor or mechanical breaker after calling for the generator to start which
will run until the system is able to operate on renewables again the following day.
The below tables show how long each configuration will be able to power the facility
on solar and storage alone, without the aid of the generator. The following was
calculated by simulating three outages of the specified length occurring randomly
throughout the year. The X represents the configuration’s ability to back up the entirety
of the building's loads for the duration specified on the left with a prior warning of the
outage such as a PSPS event. This is the estimated minimum duration. It is likely each
system could last longer in optimal conditions, such as multiple sunny days in a row in
the summer or with aggressive energy conservation.

If half of the battery is reserved for outages, configurations 3 and 4 will be able to last for
three days on renewables only if resiliency mode is enabled to proactively charge the
battery prior to the PSPS event. With additional solar, each configuration can last for at
least 4 days. Longer renewable only outage durations could be sustained by load
shedding non-critical loads. The ARC microgrid controller can automatically detect a
grid failure and open load-drop contactors as needed, either at the start of an outage
or when the battery reaches a predetermined low SOC.
The above analysis is intended to provide insight into the renewable only
(solar+storage) operation of the system. This site also has a generator which will allow
the site to sustain the full load potentially indefinitely.
The following images show the performance of the system during an outage in late
September.

The above comparison demonstrates the benefit of additional solar in lasting through
an outage. Additional solar means the batteries are more likely to be able to research
a high state of charge during an outage while supporting the loads.
The above represents sustaining the entire load though an outage through solar and
storage alone.
Microgrid Design
Syserco Energy Solutions, Inc. is proposing an AC-coupled microgrid design that would
maximize flexibility in the system. Delta Power Systems batteries and Delta PCS 125
inverter will be added to the existing solar and dual fired generator. An upgrade of the
PV inverters will be considered.
Under normal grid operations, the solar and storage will offset the load of the building,
providing TOU shifting as needed. Once they have reached the maximum state of
charge (SOC), excess solar will be exported back to the grid. A portion of the batteries
will be reserved at all times for outage events.
To island the system in the event of a grid outage, the SEL-751, a utility grade
protective relay, is being suggested. When an outage occurs, the SEL-75 will detect the
grid failure and open the contactor isolating the facility within less than a second. The

Ageto ARC controller will command the Delta PCS 125 to switch to grid-forming and
blackstart the microgrid. The solar inverters will then reconnect to the microgrid after a
specified timed delay. The integration of the generator can then operate one of two
ways depending on the upgrade of the generator controls.
The first scenario is if the genset controls are not upgraded, the generator will sit behind
an Automatic Transfer Switch (ATS). Once ARC determines the batteries to be at a low
SOC and the solar production too low to meet the needs of the facility, ARC will open
up a load-drop contractor essentially blacking out the Renewable side of the ATS. The
ATS logic will then take over and call for the generator to start. ARC will try to charge
the batteries from solar until the SOC is sufficiently high and once achieved, will close
the load contactor, and return the load to the renewable side of the ATS. Cycle
charging of the batteries by the generator will not be possible in this microgrid design
as the generator and renewables will operate on different sides of an ATS, and not be
able to operate in parallel.
The second scenario is if the generator is upgraded to allow for more advanced
control. The generator will then be able to run in parallel with the energy storage
allowing for cycle charging of the batteries and less generator run time.
Once grid health returns, the SEL-751 will automatically reconnect to the grid after
matching frequency and voltage. In all scenarios ARC will monitor and protect the
health of the assets including battery SOC limits, generator minimum loading and
runtime, etc.
Below is a one-line example of the system without the generator upgrade.

Generator Considerations
The upgrade of a generator would allow for the solar and storage to operate in
tandem with the generator during outages. Typically, a generator is installed to be at
minimum twice the peak load. Utilizing the power capacity of the energy storage
system can reduce the need to oversize the generator.
Replacing a generator would bring the advances in generators that have been seen
in the past 20 years including slight increases in efficiency and decrease in emissions.
The addition of a new generator would also bring the ability to function in conjunction
with the rest of the microgrid.
Below is a one-line example for a system installing a new paralleling and synchronizing
generator. The below design with the anticipated service upgrade would also work
with adding more stationary or mobile storage.

Solar Considerations
While the existing solar is 15 years old, the lifetime of most panels is between 20 and 30
years. The panels themselves likely do not need to be replaced, however additional
upgrades to the PV system may increase the efficiency and production of the system
while further reducing the annual cost of electricity.
Adding power optimizers and a new solar inverter could increase the power output of
the existing system, especially if some panels are shaded, which appear to be via
google. This would also bring the system to NEC 2020 code compliance and allow for
panel level rapid shutdown increasing the overall safety of the PV system required
today for a roof mounted PV Systems. Both power the optimizers and inverter can be
sourced as needed. Strong consideration should be made to choosing an Inverter that
will work with the ARC microgrid controller.
Additional solar panels can also be added to increase the total production capacity
of the array on several of the roofs including repowering the existing solar trees. We
have contacted the original manufacturer who has indicated newer and larger
modules could in fact be placed on the existing racking. The system would be
constructed with newer more efficient modules and inverters increasing the system
with a similar footprint.

Ageto Renewable Controller
A key component to the overall system functionality for solar+storage is the
technology choice we made to use the Ageto Renewable Controller (ARC),
which provides real-time optimization and control of the power system and is
the primary User Interface. ARC is currently the most flexible and most
advanced behind the meter controller for integrating into hybrid systems
possessing the ability to monitor energy usage and dispatch the energy
resources to provide reliable power at the lowest cost of energy in a
connected or islanded event. ARC will provide a web-hosted dashboard, so
the power system is able to be remotely monitored or displayed in the front
office to engage with customers and employees.
Figure 9: Ageto’s Web-Hosted Dashboard
The ARC microgrid controller will automatically monitor and control the energy
resources in the system to meet the desired goals and operations of the
system. It will operate locally for the lifetime of the system to bring additional
value and savings out of the assets.
In preparation of the recent New Orleans, LA. hurricane a preparatory
resilience mode was integrated into the ARC. This feature, when enabled, will
inform the controller an island event is coming. It stops the discharge of the
battery for demand and TOU shifting maximizing the amount of time the
system has to fully charge the battery energy system thus providing the longest

possible renewable power source during the island event. This is a perfect
solution to California Utility PSPS notifications of upcoming events.
Results Summary
The addition of battery storage will meet the goal of the project adding an
additional layer of power resilience to the Los Altos Hills Town Hall and allow
the facility to operate on renewables only during outages for a period of
time.
The major drivers for choosing the battery sizing for this system is the available
budget and the desired length of renewable only operation in the event of a
grid outage, 72 hours.
The upgrade of other aspects of the existing system may be desired to
improve the overall performance of the system including the duration of
renewable resilience and ability of the entire solution to work in harmony.
With the proposed solution, the project will be able to operate in island mode
regardless of the upgrade of the generator or PV inverters. However, the
upgrade would allow for cycle charging, the low power generation from the
generator to strategically charge batteries at certain times and or states of
battery charge or both. Additionally, upgrades to the PV system could
increase the overall power output. Additional solar could be added to
increase the production and charge a larger energy storage system faster in
a grid outage.

Final Thoughts
We believe the proposed resilience project that includes 125kW / 340 kWh of
BESS utilizing the Ageto Energy ARC microgrid controller meets the Town’s
original project goals and budget. This project coupled with the service
upgrade of 1200AMPs provides the Town the necessary infrastructure for
today and future electrification, integration of additional energy storage and
additional PV Solar.
