Hawaii’s 100% Renewable Energy Goals: Status and Issues
Although the Hawaiian Islands are blessed with an abundance of renewable energy sources including excellent solar and wind resources, and have the nation’s most aggressive renewable energy standards, the state still rely heavily on fossil fuels for electricity generation. With isolated (unconnected) island grids and sparse systems on some islands, integration of the intermittent renewable generation systems has been challenging. The Hawaii Natural Energy Institute (HNEI) at the University of Hawaii has initiated an integrated effort involving modeling, testing, and demonstration to identify and validate pathways to higher renewable integration. In this talk, I will discuss the analysis being used to identify strategic paths forward and will describe several projects currently underway including the Maui Smart Grid Demonstration Project, the Smart Grid Inverter Project and several grid-scale battery energy storage projects.
DR YUICHI KADO
The JUMP Smart Maui project implemented from 2011 to 2016, which Hitachi led as the key technology provider together with several industrial stakeholders in Japan and Hawaii, was engaged in the development and demonstration of Vehicle to Grid integration in Maui.
The objective of the project is to install and operate infrastructure to help the island transition to clean energy to transportation and also to help electrical grid introduce more renewables by utilizing distributed energy resources especially electric vehicles (EVs).
The project integrates 13 stations / 44 ports of DCFC charging stations and also 200 home chargers for V1G and 80 home chargers for V2G. The number of EVs in Maui was around 80 on starting the project in 2011. At the end of the project, the number of EVs went up around 780 in 2016. The number of DCFCs is still more than 300 users in 2018.
Regarding the contents of technology demonstration, V1G demonstration includes tests of home charging behavior in peak period of grid demands and managed charging based on utility’s and the participants’ needs with 200 houses participants. V2G demonstration includes tests of managed charging and discharging with 80 Hitachi bi-directional chargers.
With the depth and breadth of experiences above, after this demonstration in 2016, Hitachi and our partners are expanding V2X capabilities, which includes assessment demonstration of estimated capacity of aggregated EV batteries with bi-directional chargers and frequency control with Hawaiian utility company.
As the result of experiences in Maui demonstration, Hitachi has established technology confidence in V1G and V2G functions. Key device, EV power conditioning system, is also developed with our partner “IKS” and upgraded as “Hybrid PCS” with bi-directional charging functions integrating EV, PV and battery with CE and UL certifications. Hybrid PCS has been used by our customers in Japan U.S.A. and Europe since 2018.
These movement tightly related to DC (Direct Current) technologies and telecommunication technology expansions, to show the future direction of DC technology, Hitachi also introduces new partner in this area. Dr. Yuichi Kado will introduce the latest tecknology, Triple-Active-Bridge Converter and the demonstration utilizing those converters experimented on distributed network.
We believe that these various potentialities of EV are getting bigger very quickly and these unique aspects will be commonly used as a part of distributed energy resources and lead a key device of compact city in the future.

EXECUTIVE DIRECTOR, PACIFIC POWER ASSOCIATION
The PPA is an inter-governmental agency and member of the Council of Regional Organisations in the Pacific (CROP) to promote the direct cooperation of the Pacific island power utilities in technical training, exchange of information, sharing of senior management and engineering expertise and other activities of benefit to the members.
The PPA’s objective is to improve the quality of power in the region through a cooperative effort among the utilities, private sector and regional aid donors. The PPA’s members pool their resources and expertise for their common benefit, gain international representation and improve access to international power sector assistance programmes.

CHIEF OPERATING OFFICER, ENERNET GLOBAL
Simon is chief operating office and Asia pacific managing director for Enernet Global. Simon was formely with Hydro Tasmania including roles as Manager, Hybrid Off-Grid Solutions and Project Director for the King island Renewable Energy Integration Project (KIREIP). Simon was awarded a 2010 Fulbright Academic Exchange Scholarship, having previously been acknowledged under the Australia Korea Foundation: Next Generation Leaders Program.
HYBRID MICROGRID DEPLOYMENT IN THE COMMERCIAL AND INDUSTRIAL SECTOR
Enernet Global implements microgrids in the traditional off-grid sectors, such as remote communities and the mining sector. In recent months the deployment of microgrid technology to grid connected clients in the commercial and industrial sectors is becoming more prevalent, as behind the meter solutions are offering cost effective solutions to traditional retailed energy services.
Commercial microgrids also offer enhanced energy services with increased levels of energy security and reliability and the prospect for seamless islanding where grids offer less than acceptable reliability.
Enernet will outline how the economics of solar PV and energy storage, and the integration of these systems into on-site load and demand management is driving a whole new class of renewable microgrids.
RAY MASSIE
MANAGER OFF-GRID HYBRID SOLUTIONS, HYDRO TASMANIA
Hydro Tasmania are Australia’s largest renewable generator, and have a comprehensive track record in assisting remote island communities switch to reliable clean energy systems.
The Flinders Island development involves integration of wind and solar generation with the existing diesel power station and the installation of enabling technology, such as a control system, flywheel, dynamic resistor and battery energy storage. Hydro Tasmania has worked with Tasmanian manufacturers to develop a series of modular units to house and ship the enabling technologies essential to the energy solution.
Equipment was fabricated and tested off-site, ensuring a speedy rollout at the final location, reducing the risk, cost and duration of construction. The modular units provide a lower cost and scalable solution that will allow easy and rapid transport and installation for renewable energy projects and can also serve temporary generation, such as in disaster relief or in the mining industry.
Since commissioning in late 2016 the Flinders Island hybrid energy hub has run 100% renewable for half of the time.
JAMES HAMILTON
UNIVERSITY OF TASMANIA
Australian utilities are at the fore of innovative diesel based enablers, able to substantially reduce the cost and complexity of high penetration renewable integration. The technology progression can be traced back to 2003, with low load diesel units commissioned within the Denham wind diesel system. More recently the application has been validated across a range of utility application including Rottnest Island and King Isand. King Island has set a number of records including a sustained and stable diesel off capability, in addition to hosting Australia’s largest battery energy storage system. This presentation also covers the development of variable speed diesel platforms, a natural extension to low load application, providing for efficiency improvements of 40% at low load. The technology provides a pathway to renewable integration without a requirement for battery storage, significantly reducing the cost and compexity of system hybridisation.
