• 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
