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:
• When we use electricity
• How we use electricity
• When we make electricity
• How we make electricity
“County of Kauai will achieve
an 80% emissions reduction in
County Operations by 2023”

Our Goals Align!

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.

Looks
simple,
right?

LED Street Light Retrofit

5. LED Street Light Retrofit
Benefits:
• Reduced energy consumption
Reduced maintenance
• Reduced burn time/dimming
• Better illumination and control
Challenges:
• Getting the standards right
• Getting the RFP right
• Getting the price right
• Getting the tariff right
…or close enough
Current cost of County
Street Lights to Island
residents
$1m/year
HCEI December 6 2013 County of Kauai Update 5
Possible CapX:
• Fixtures at $200-$400 ea.
• Controls at $100-$300 ea.
• Install costs?
• At $500/fixture = 2800 x $500 = $1.4m
• At $700/fixture = $1.96m
• At $900/fixture = $2.52m
Possible Annual Savings:
• Reduce kWh 50% = ($390k)
• Reduce maint. = ($150k)

6. Electric Vehicles & Fleet Efficiency
Moving forward with EV’s
• Using LEAF’s in ‘Green Motor Pool’ Pilot
• Working with KIUC on charging network
• Support an ‘EV charging rate’ from KIUC
Planning an expanded motor pool:
• Reduce # of vehicles in fleet
• Increase usage of each vehicle
• Increase average vehicle efficiency
• 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. • EV Rental Mandate – Should we consider a rental car policy
that requires employees of State and County to rent EV’s
when they are available ? (provides a backstop for rental car
companies to promote EV adoption in rental fleets)
– Reduces fuel costs
– Possibly reduces parking costs (short term only)
– Increases EV adoption
– Assures early market for vehicles
– 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
• Electric utility data fully
uploaded summer of ’13
• Data is in monthly intervals lags
by 2 months + (billing data)
• Energy use ‘creeps’ up every
year without intervention
• Departmental energy planning
in early stages
• Important to provide tools to
allow broader engagement at
Department level
• Planning for continuous
improvement in tools and data
quality
• Implementing this (imperfect)
system was important 1st step

9. Energy & Utility Data – What’s 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?
