• Established in 1974 by the Hawaii State Legislature to coordinate and
develop natural energy sources for Hawaii.
• 2007 ACT 253, expanded this mandate to coordinate with state and federal
agencies; and to demonstrate and deploy efficient end use technologies,
including those that address peak electric demand issues.

Making of the Maui Smart Grid
• Maui Smart Grid Project (2009) ~$12 M
– US DOE funded, HNEI led project to integrate smart grid technology to
achieve reduced peak load on a distribution circuit and better
management of intermittent renewable energy
• Smart Grid-Enabled PV Inverters (2012) ~$11 M
– US DOE/ONR funded, HNEI led project to develop and demonstrate
advanced PV inverter functionality in a smart grid environment
• JUMP Smart Maui (2011) ~$35 M
– NEDO funded, Hitachi led project to integrate high levels of PV, wind
energy, and EV into an island wide smart grid environment
• Great Maui Project (2013) ~$20 M
– NEDO funded, Hitachi led phase 2 of JUMP Smart Maui project, to
demonstrate EV vehicle-grid and Virtual Power Plant integration
All projects have partners in common and
propose to share hardware, results, and
lessons learned6
• Funded by US DOE with cost share from partners
• Implement advanced communications and control
technologies to improve grid performance
• Demonstrate new “Smart Grid” technologies to:
– Reduce peak demand by 15%
– Better integrate wind and solar power
– Improve grid reliability
– Inform consumer demand decisions
