2. But how will we do it?
1. Reduce fleet fossil use use by 50%
2. Reduce Electricity Consumption by 30%
3. Collaborate with KIUC to transform our energy
use and production:
โข When we use electricity
โข How we use electricity
โข When we make electricity
โข How we make electricity
โCounty of Kauai will achieve
an 80% emissions reduction in
County Operations by 2023โ

3. County - KIUC Collaboration
Executed Aug 15 2013
WHEREAS, because KIUC and the County share similar goals in reducing the use of fossil
fuels, reducing carbon based emissions, and lowering the overall cost of energy for the
citizens of Kauai, an opportunity exists for the parties hereto to explore alternative rate
structures, collaborate on transactions, and share technical and engineering resources in
order to maximize benefits for the shared constituencies of both parties.

4.Shared PV & Battery Storage Installation at Kauai Police Dept./Civil Defense
5. Waimea Wastewater PV/TOU Rate Pilot
6.Water Dept. PV/TOU Pilot
7.Electric Vehicle Market Development
8.Energy Savings Performance Contracts
9. Partnership at Kekaha Landfill for optimal development of landfill methane
10.Shared Gas Storage at Kapaia
11.Integration of County gen sets for KIUC Emergency Dispatch
Possible projects
5. LED Street Light Retrofit
Benefits:
โข Reduced energy consumption
Reduced maintenance
โข Reduced burn time/dimming
โข Better illumination and control
Challenges:
โข Getting the standards right
โข Getting the RFP right
โข Getting the price right
โข Getting the tariff right
โฆor close enough
Current cost of County
Street Lights to Island

$1m/year
HCEI December 6 2013 County of Kauai Update 5
Possible CapX:
โข Fixtures at $200-$400 ea.
โข Controls at $100-$300 ea.
โข Install costs?
โข At $500/fixture = 2800 x $500 = $1.4m
โข At $700/fixture = $1.96m
โข At $900/fixture = $2.52m
Possible Annual Savings:
โข Reduce kWh 50% = ($390k)
โข Reduce maint. = ($150k)
6. Electric Vehicles & Fleet Efficiency
Moving forward with EVโs
โข Using LEAFโs in โGreen Motor Poolโ Pilot
โข Working with KIUC on charging network
โข Support an โEV charging rateโ from KIUC
Planning an expanded motor pool:
โข Reduce # of vehicles in fleet
โข Increase usage of each vehicle
โข Increase average vehicle efficiency
โข Specific targets & details TBD
Electric Vehicles are an important long term piece of a much
bigger effort to transform the transportation sector. They are also
important to provide load growth for our utility cooperative.

7. โข EV Rental Mandate โ Should we consider a rental car policy
that requires employees of State and County to rent EVโs
when they are available ? (provides a backstop for rental car
companies to promote EV adoption in rental fleets)
โ Reduces fuel costs
โ Possibly reduces parking costs (short term only)
โ Increases EV adoption
โ Assures early market for vehicles
โ Exposes potential EV buyers to product
HCEI December 6 2013 County of Kauai Update 7
One little idea to advocate for
8. Energy & Utility Data
โข Electric utility data fully
uploaded summer of โ13
โข Data is in monthly intervals lags
by 2 months + (billing data)
โข Energy use โcreepsโ up every
year without intervention
โข Departmental energy planning
in early stages
โข Important to provide tools to
allow broader engagement at
Department level
โข Planning for continuous
improvement in tools and data
quality
โข Implementing this (imperfect)
system was important 1st step

9. Energy & Utility Data โ Whatโs Next?
HCEI December 6 2013 County of Kauai Update 9
10. What we have:
1. A lot of methane (more than 2x what
we currently use in our fleet)
2. A lot of trucks and busses
3. A large annual vehicle fuel bill
4. An expectation that our fleet fuel
demand will grown significantly
What we need:
1. A backup supply of gas!
2. More trucks and busses using CNG now
3. A CNG fueling station
Kekaha Landfill Gas Utilization
Is renewable gas in heavy vehicles an important part of our
HCEI transportation goals?
