Moku o Lo’e DC Microgrid(Coconut Island)
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

Hawai’i has a long tradition of pioneering
advances in energy ….
On November 16, 1886 -- Kalakaua's birthday --
’Iolani Palace became the world's first royal
residence to be lit by electricity.
