Test advanced clean energy technologies and integrated control strategies such as:

Coconut Island offers a unique opportunity

for technology and material testing:

• Scale: ~0.5 MW grid connected microgrid

• UH owned/controlled island facility

• High penetration of distributed renewable

energy resources (particularly rooftop PV)

• Marine research laboratory with critical loads

and high energy reliability needs

• Persistent coastal winds result in a highly

corrosive marine environment yielding a

micro-climate representative of harsh island

conditions

• DC distribution, motors, & lighting

• Photovoltaic systems

• Small-scale wind turbines

• Energy storage systems

• Fuel cells

• Alternative fuel vehicles (EV car/boat)

• Building controls & energy efficiency

• Load management

• Advanced communications and

microgrid control

• And more ….

Background

• University of Hawaii Institute of Marine Biology utilizes the island to

conduct marine research with life support equipment for the marine

organisms under study and other critical energy needs

• Average schedule G & J electricity rates for 2014 were $0.35/kWh and

$0.31/kWh respectively

• Service interruptions result in significant efforts to get systems running

again and poses risks to active research

• Coconut Island’s peak system demand is approximately 500 kW

• 200 kW of PV installed on rooftops at present (per PPA with Solar

City)

• Two diesel generators (200 kW and 240 kW) on island for emergency

back-up power to select load centers5

Project Objectives

• Reduce electricity costs

• Understand and address power quality issues

• Implementation of renewable energy technologies

• Provide reliable service to select critical loads in the event

of loss of grid power while minimizing diesel fuel use

• Demonstrate the use and value of DC distribution systems

• Demonstrate the use and value of a microgrid control

system

• Fuel cell test – PV, water source (fresh / salt), O2 usage

• Assess salt laden coastal environment impacts on

microgrid equipment

advances in energy ….

On November 16, 1886 -- Kalakaua's birthday --

’Iolani Palace became the world's first royal

residence to be lit by electricity.
