  2. Who/What • R. Rocheleau – Setting the stage • A. Seki – Utility perspective • B. Parks - Why this is important on a national level • R. Rocheleau – HNEI programs • T. Surles – Hawaii Energy Resource Technologies for Energy Security

  3. Hawaii’s Renewable Energy Sources • Wind (commercially viable on all islands - siting and integration) • Solar PV and hot water (commercial - PV cost) • Geothermal (30MW, permit for 60MW - utility need) • Biomass (transportation and electricity use - land use, crop selection and conversion technology) • Municipal Solid Waste (commercial but limited) • Run-of-river hydro (commercial - very limited resource) • Pumped hydro storage (good potential - siting) • Ocean thermal (excellent resource - technology and cost) • Wave (excellent resource - technology and cost) • Current (via tides, limited potential)

  4. Renewable Resource Mix and Energy Issues Provides Unique Opportunities for Hawaii • Varied and substantial mix of renewable resources • Unusually high dependence on petroleum for electricity – over 80% • Very high cost of electricity – over $0.30/kwh ( some islands) • Highest in nation gasoline costs – over $ 2.70 per gallon • Substantive transmission and distribution issues – mountainous terrain, sparse system. • Unique and substantive difference between peak load vs. base load requirements - available renewable energy taken off line • Changing housing requirements leading to need for linking solar/efficiency • State government focused on contributing to energy solutions • Hawaiian different from mainland utilities

  5. Special Considerations for UsingRenewable Energy in Hawaii • Hawaiian utilities are different from mainland utilities • Relatively small utility systems • No grid interconnections • Reliability is critical • Many renewables not continuously available (solar, wind, hydroelectric) • Still need generation we can dispatch on demand

  6. Partnerships are Needed • Research, development & demonstration projects with the Federal and State government, universities • MOD-OA and MOD-5B Wind turbines at Kahuku, Oahu • HGP-A geothermal power plant in Puna, Hawaii • OTEC study at Kahe power plant, Oahu • Biomass feasibility studies on Maui and Hawaii • Hawaii deep water cable program • Pumped storage hydroelectric studies

  7. Renewable Energy Challenges • As-available and firm power • Wind penetration limits • Curtailment during the off-peak • Technology costs are high • Various stage of technical development or maturity • Site specific or land intensive issues • Environmental impacts

  8. Why is Grid Modernization Important? Outages and Power Quality Disturbances Cost the U.S. $79B Annually LBNL Base-Case Estimate of the Cost of Power Interruptions by Types of Interruption Frequency of Outages and Disturbances $26 Billion $52Billion * *Interruptions lasting five minutes or less are considered momentary interruptions.

Source: NERC Systems Disturbance Reports, 1992-2003. Public Interest at Risk • Reliable electric service • Costs of manufactured goods • Productivity of businesses and industry • Costs to states and local governments

  9. Distributed Energy Resources Interconnection Technologies Electric Power Systems Fuel Cell Utility Grid Inverter Microgrids • Functions • Power Conversion • Power Conditioning (PQ) • Protection • DER and Load Control • Ancillary Services • Communications • Metering Wind Microturbine Energy Storage Loads Generator PV Local Loads Load Simulators Switchgear, Relays, & Controls Systems Integration

  10. Microgrids • Definition • A microgrid is an integrated energy system consisting of interconnected loads and distributed energy resources which as an integrated system can operate in parallel with the grid or in an intentional island mode • Significance • Microgrids can deliver several value propositions including reduced cost, increased reliability & security, green power, service differentiation, and power system optimization.

  11. Hawaii Natural Energy Institute • Established by the Hawaii Legislature in 1974 to assist the state in developing Hawaii’s renewable energy resources; • Research unit in the University of Hawaii’s School of Ocean and Earth Science and Technology; • Staff includes permanent faculty, scientific staff, post-doctoral fellows, graduate students, and administrative support (about 60 total); • Research programs: • Hydrogen – renewable hydrogen production; • Fuel Cells– testing, modeling, and development; • Ocean resources – seabed methane hydrates; • Photovoltaics – thin film solar cells; deployment and testing • Biomass and biotechnology – gaseous, liquid and solid fuels; • Renewable & distributed energy systems - deployment, demonstration, and integration

  12. Hawaii –New Mexico Partnership Builds upon Existing Partnerships • 2000 – Hawaii Hydrogen Feasibility Study: id’d need for partnering • 2000 – HI Act 283: $250K to establish H2 Partnerships • 2001 – Hawaii Energy and Environmental Technology Initiative: ONR funding for fuel cells and methane hydrates • 2001 – Hawaii Gateway Energy Center focus put on distributed energy systems • 2002 – Hawaii Hydrogen Power Park: significant commercial cost-share • 2004 – Hawaii Hydrogen Center for Development and Deployment of Distributed Energy Technologies: expansion of partnerships beyond H2 and Fuel Cells • *2006 – Hawaii – New Mexico Sustainable Partnership for Energy Security: addresses grid issues • *2006 – Supplemental Funding for Section 355 EPAct 2005
