examples of prior coordination with municipal utilities.
Project 1: Stebbins, Alaska, 720 kW / 864 kWh
Client: Daylight Energy Services
Completion Date: October 2023
Kronus designed, assembled, and commissioned with
AVEC a 720 kW/864 kWh BESS in Stebbins. The system
provides microgrid support, stabilization, Toad shifting,
and generator -off operation. The customized battery
control system allows the village to integrate the BESS
into their existing microgrid controller that manages
generators and wind turbines. The BESS is in a rugged
and durable container containing Pylontech batteries and Oztek RS40 inverters for their robust
nature and capacity.
The BESS, wind turbines, and generators work in parallel to optimize usage and the operating
costs of the village. The Stebbins -St Michaels microgrid has reduced diesel fuel consumption by
36% in the first year by allowing the wind and diesel generation to seamless integrate in diesel -
off or low -load scenarios.
To reach this desired outcome, Kronus provided system design & customization, temperature
calculations, system assembly, complete system testing, onsite installation, and commissioning
in Stebbins. We coordinated with representatives to arrange housing logistics at the local
elementary school.
Project 2: Manley Hot Springs, Alaska 240 kW/287 kWh

KronusEngineering.com I info@kronusengineerine.com 15490 Western Ave, Boulder, CO 80301
V; Kronus Engineering
The Battery
of the BESS is to enable the shutdown of one of the three diesel generators, resulting in
significant diesel fuel savings —potentially hundreds of thousands of dollars annually. In addition
to serving as a spinning reserve for the remaining generators, the BESS is also intended to
provide backup for future renewable energy sources, including wind turbines and solar PV.

3. Description of warranty and O&M management for the lifetime of the equipment
Kronus shall guarantee all the work completed against any defects
resulting from Kronus' performance and/or Kronus furnished
materials for the period of one year after final inspection and
acceptance of the work. During the guarantee period, any defects
found attributed to Kronus' responsibilities shall be corrected by
Kronus accordingly at no additional cost. Unless otherwise
stipulated herein, Kronus shall guarantee Kronus' workmanship of
the work completed for a one-year period from the date of the COS'
acceptance of the work completion. During the warranty period, Kronus shall correct and/or
repair, at no cost, any damage and/or deficiencies that may be attributed to the materials and
workmanship provided by Kronus. Kronus shall provide all labor, materials, equipment, at their
own expense, to perform the repair and/or correction. Kronus shall pass on all OEM product
warranties to COS.
Kronus Engineering recommends the BESS system should undergo regularly scheduled
maintenance (monthly, semi-annually, and annually) to ensure proposer system function and
longevity. Please ensure that access to the BESS is limited to authorized, trained, and qualified
personnel. Prior to the commissioning of the system an O&M manual and plan will be agreed
upon with COS specific to COS's needs.
4. Description of proposer's battery augmentation approach
Kronus Engineering's approach is to consistently collaborate with our customers over the first
year to improve performance. By analyzing usage patterns, load profiles, and operational goals,
we develop tailored solutions to maximize the efficiency and longevity of the BESS. This includes
optimizing charge and discharge cycles, implementing software updates, and enhancing
operational practices. Through this customer -centric approach, we ensure sustainable
performance without requiring significant system replacements.
5. Description of site acceptance testing
Commissioning — Our standard process is to work with the customer to create test and
commissioning plans in the design stage. Typically (2) test plans are put together: a system test
plan for Factory Acceptance Testing (FAT) and an on -site test plan for Site Acceptance Testing
(SAT).
1. The system functional test plan is performed to demonstrate that the BESS functions as
required prior to leaving our facility. Clients have the choice to visit the site for this test,
take part remotely, or for Kronus to provide test reports once completed. This process
usually takes between a few hours to a few days depending upon the agreed test plan. It
can also involve renting additional equipment to speed up testing. For example, if the
KronusEngineering.com I info@kronusengineering.com 15490 Western Ave, Boulder, CO 80301
011; Kronus Engineering m-
e BatteiyExperts
client wants to see a full discharge from full to empty, a 1.5 MWh load bank could be
utilized to discharge in 1 hour or a 15-kWh load bank could make the test run 100 hours.
2. A second set of testing is done on site and usually involves a full test of the key tasks and
functions the client would like to see demonstrated. Installation and commissioning
usually take 1-2 weeks and involves members from our team onsite until the system is
properly commissioned.
6. Onsite Training
Kronus Engineering will put together a complete operational manual that details the system and
provides maintenance and other operation information. Our engineers onsite will complete a
thorough system walkthrough with selected local operators to ensure they have a good
understanding of the system enough to provide basic troubleshooting.

f. Fire mitigation system.
Saft's fire mitigation system is composed of mainly two components:
1. Fire and Gas Detection System
2. Explosion control
Detection is conducted through an industrial fire control panel with the following main
characteristics:
• SIL 2 System: Control panel and detectors
• ATEX Flammable Gas Detector
• Autonomous System: Each container has its own control panel, preinstalled at Saft's
manufacturing site
• Detection Capabilities: Fire, flammable gas, and thermal runaway detection
• Remote Control and Monitoring: For all BESS units
• UL and CE Certified Solution
• NFPA Compliant: NFPA 72
• Autonomy: 24 hours in standby and 2 hours in alarm
The risk of explosion in the BESS container is mitigated using two independent systems: a
passive (exhaust circuit connected to each module's venting valve) and an active system (two
ATEX exhaust fans — compliant with NFPA 855 and 69). The objective of these systems is to
maintain the concentration of flammable gas below 25% of the Lower Flammable Limit (LFL)
withing the container's free volume.

6. Expected monthly consumption and peak power of auxiliary loads. Operating losses
will be evaluated at COS' cost per kW-hr
The auxiliary load consumption is extremely temperature and Toad dependent. For worst case
high temperature sites, we see up to 40kWh per clay but can be as low as 5kwh per day in
cooler temperature climates where the system heats itself. The fuel source for heat can also
change the auxiliary loads.
7. Control system specifications including interface data requirements, network
parameters, and required communication protocols.
The main requirement to have remote capabilities is internet connection. Communication
parameters are dependent on the system we are connecting to. Modbus is the most common
way to integrate, but we can integrate with any common industry SCADA system protocol.
8. Low and high voltage ride through capabilities, inverter protection
EPC inverters have configurable low and high voltage ride through capabilities in their
configurable settings. These settings will be set in the design phase based on project
pa ra meters.
9. Decommissioning strategy and cost assumptions for battery disposal and equipment
removal
The end of life for Lithium -Ion Batteries is a shifting target that many energy storage systems
need to evaluate as they embark on energy storage projects. Stationary Storage batteries
usually have EOL state of health where they may not be appropriate for stationary storage
applications anymore, but other downstream applications such as forklifts or bicycles may be
able to utilize the technology for an additional 10 years. Kronus is committed to helping find a
second life application, preferably locally, for batteries when they reach their End of Life for this
project.
10. Description of proposer's ability to support islanding and black start scenarios
Kronus has delivered multiple BESS systems capable of grid -following to allow for continued
power in the event of a generator tripping offline and grid -forming operations to restore full
power in "black start." Many of our systems deployed work seamlessly with generators and
renewable power to ensure that the village is not lost without power.
