Richard Rocheleau (PhD, Chemical Engineering, University of DE), has over 35 years of experience in renewable energy, with an emphasis in the areas of photovoltaics, hydrogen fuel cells, and energy systems. Dr. Rocheleau joined the faculty of the Hawaii Natural Energy Institute at the University of Hawaii in 1988 and was appointed Director in 2000. Under his direction, the Institute is leading the development of public‐private partnerships focused on the development, testing and integration of alternative energy technologies into the electrical grid. HNEI has major funding from the US Department of Energy and the Office of Naval Research. Dr. Rocheleau was also successful in positioning the Institute to receive a portion of the ‘barrel tax’, established by the Hawaii State Legislature supporting studies for integration of renewable energy technologies into the grid intended to assist the state to meet its aggressive renewable energy portfolio goals.
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.
Executive Director, Pacific Power Association
Andrew Daka is currently Executive Director of the Pacific Power Association (PPA) an inter-governmental agency and member of the Council of Regional Organizations in the Pacific (CROP) to promote the direct cooperation of the Pacific island power utilities in engineering expertise, technical training, exchange of information, sharing of senior management and 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 provides direct links between the private sector and member utilities to improve private sector services and thus make their presence in the region more productive.

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.
King Island Renewable Energy Integration Project
King Island Renewable Energy Integration Project delivers the worlds most advanced MW scale remate area power system. Located on the remote Bass Strait island, the initiative has transformed the power system from one 100 per cent reliant on diesel power, to one able to run diesel off. The system has amassed over 5000hrs diesel off operation, showcasing a number of renewable and enabling technologies.
The King Island experience has a waelth of insight to share, with the system providing technology guidence to a number of subsequent developments, including Flinders Island and Rottnest Island.
Manager Off-Grid Hybrid Solutions, Hydro Tasmania
Flinders Island Hybrid Energy Hub
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 is a researcher at the University of Tasmania, leading implementation of the King Island low load diesel research and Rottnest Isand variable speed diesel programs. He is currently a director with Renewable Ready and has formerly held roles as director of Joule Logic, a specialist renewable energy IPP and consultancy who develop, deliver and own embedded wind power systems across Australia (including Flinders Island), and as Senior Commercial Engineer with Windlab Systems. James has worked within the renewable sector for over a decade, across roles in Australia, Indian, China and South Africa.
Australian Low Load & Variable Speed Technology Case Studies
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.

Variable Speed Diesel and Natural Gas Generation for 100% Renewables Integration
Today’s sophisticated microgrids are challenged by operating with 125-year-old synchronous generation technology. Complex systems, controls, and storage are required to maintain grid stability when integrating high penetration renewables. Using power electronics to enable Variable Speed Generation (VSG) optimizes efficiency by allowing the generator’s engine to operate at optimal speeds for any load and maintains microgrid stability at any renewable penetration by producing power through a back to back converter platform.
This presentation discusses technology advances that eliminate the need for storage to provide grid stability for high penetration renewables, therefore significantly lowering the levelized cost of energy.
We will discuss the results of the Waterloo Institute for Sustainable Energy report, “Feasibility of Variable Speed Generators for Canadian Arctic Communities”. The report demonstrates how the use of converter-based generation significantly lowers emissions, fuel consumption and provides the lowest LCOE for remote northern community renewable integration.
We will also review the results from a recent installation of a 590kW VSG installation in the community of Aklavik Northwest Territories Canada.
