farming operations; 113 out of 147 applications (27 states) have been
funded; and
- Federal wind production tax credit extension included in pending Energy
Bill - (likely to be heard by Congress in January or March 2004).
2. Dennis Elliott provided an overview of NREL's state mapping and validation
project.
D. Elliott's presentation (choose one):
Key points included:
- D. Elliott provided an overview of wind mapping approach, validation
process, land factors and exclusion criteria, and project schedule;
- NREL is in the process of validating state high resolution wind resource
maps;
- As part of the validation, NREL is trying to identify the nature of
anomalies;
- D. Elliot indicated to the HWWG that comments on the maps should be
received as soon as possible and not after completion of the validation;
- Maps developed by TrueWind Solutions, the leader in wind mapping development;
- Numeric weather simulation model will provide wind maps with a grid
resolution of about 200 meters;
- Good wind sites - Class 4 or higher (Class 5 or higher preferred);
- NREL currently using State GAP data to determine available windy areas
and electric potential (NREL assumes about 5 MW/sq. km);
- NREL not considering transmission & distribution limitations (e.g.,
distance to T&D lines);
- D. Elliott does not anticipate significant changes to the preliminary
maps after validation;
- NREL not validating offshore wind data; only near-shore results will
be validated;
- Validation consultants are under contract (NREL, GEC, John Wade, and
Rich Simon) for Hawaii wind maps; and
- Validation of Hawaii maps expected to be completed by 4/15/04, with
final maps completed by 5/15/04 and the calculation of Hawaii's wind
electric potential completed by 6/1/04.
3. D. Ishimura provided an overview of the preliminary high-resolution
wind maps for Oahu, Maui, Molokai, and Lanai.
- Effort jointly funded by NREL, HECO, and DBEDT;
- Maps show wind power densities (W/sq. meter) at 50 meters and wind
speeds (m/s and mph) at 30, 50, 70, and 100 meters;
- Grid resolution is 200 meters;
- Accuracy is ~7% or ~¾ of a wind class;
- Maps used to identify general locations of wind resource -- cannot
secure financing for wind farms using wind map data (still need micro-siting
and met data collection);
- Islands dominated by northeasterly trades (statewide map shown);
- Trades affected by mountain ranges of islands --> result in channeling/accelerating
of winds between islands;
- Channeling/acceleration can also be observed on an island (between
mountain ranges);
- Oahu map shown:
- Kahuku, Kaena Point, and Kahe -- Wind Class 4-6
- High wind power density in Kahe area likely due to the acceleration
between Waianae and Koolau mountain ranges (also low pressure area
behind southern edge of Waianae range)
- Maui, Molokai, and Lanai wind map shown:
- Pauwela Point, Maui -- Wind Class 4-6;
- Kaheawa area of Maui -- Wind Class 7 (likely caused by acceleration
between mountain ranges);
- North, northwest, and central leeward side of Molokai -- Wind
Class 4-6
- Northwest and west side of Lanai -- Wind Class 4-6.
4. M. Tome provided an overview of the preliminary high-resolution wind
maps for the Big Island and Kauai;
- Big Island map shown: North Kohala, Lalamilo area, Puna, and South
Point -- Wind Class 4-7
- Kauai map shown: Northern area -- Class 4-7; Port Allen/Kalaheo --
Class 4-5; Southern area near Poipu -- Class 4
5. Roundtable discussions and updates of wind projects were conducted.
Key points covered included:
- D. Ishimura reported that HECO created a non-regulated subsidiary
in Dec. 2002 called Renewable Hawaii:
- Purpose of Renewable Hawaii is to invest in renewable energy projects
in the State to stimulate the renewables market and to bring renewable
energy generation on-line as quickly as possible;
- Projects must use commercial/proven technologies and be 1 MW or
greater (no RD&D);
- Renewable Hawaii expects a financial return on its investment;
- Released Renewable Energy Request for Project Proposals (RE RFPP)
for Oahu on May 22, 2003; closed on August 22, 2003:
- 8 proposals received; 3 passed screening and are currently
in detailed evaluation phase;
- Released RE RFPP for Maui County on Sept. 4, 2003; closed on Dec.
4, 2003:
- 5 proposals received and are currently being screening/evaluated;
- RE RFPP for Big Island targeted for release in next few months.
- D. Ishimura reported that HECO is teaming with a private company to
develop a commercial device installed between wind farm and utility
grid (referred to as Electronic Shock Absorber):
- Device helps utility ride through short duration power fluctuations
(frequency, voltage, etc.) from wind farm caused by gusty winds;
- Consists of power electronics and storage technology (does not
address off-peak generation issue);
- HECO has filed patent application and study done to identify available
technologies; and
- Plans are to build prototype unit by end of 2004 - uses proven
off-the-shelf components in a unique package (not building new components);
- Ultimate goal is to allow more wind on the utility system.
- D. Ishimura reported that HECO and HELCO are partnering with DBEDT,
County of Hawaii, and State Dept. of Agriculture to conduct a study
to identify potential for in-line hydro and pumped storage hydro in
existing County, State, and private water systems:
- Funded by DBEDT and HECO;
- Explore the use of wind energy to address curtailment issue; and
- Use wind during off-peak hours to pump water to higher elevation
and generate power through in-line hydro units during on-peak hours.
- G. Chung reported on activities involving native Hawaiians and wind
energy:
- G. Chung working with the Office of Hawaiian Affairs (OHA);
- A proposal for renewable energy-based projects is being drafted
for Kamehameha Schools;
- Native Hawaiians are interested in rural power projects;
- G. Chung inquired if the HWWG is considering off-grid renewable
energy projects (i.e., self-powered applications) on native lands;
- A series of workshops are being coordinated for March 2004; and
- Any members interested in upcoming workshops are to contact G.
Chung via e-mail, at gcchung@makani-o-kau.com
- S. Ishikawa reported on a Utility Wind Interest Group (UWIG) project
to develop assessment tools related to grid quality:
- Purpose is to determine voltage fluctuations caused by wind farms
on distribution feeder lines;
- Software is being beta tested by HECO;
- Software calculates voltage fluctuation and voltage flicker;
- Beta testing is utilizing the proposed Hawi wind farm because
it was an ideal candidate (i.e. relatively small wind farm compared
to mainland standards on a radial line); and
- Results expected to be made available to UWIG members.
- S. Ishikawa reported on the Intermittent Generation Assessment Protocol
(IGAP) project:
- HECO collaborating with EPRI and utilizing Eletrotek Concepts,
Inc. as the consultant conducting the analysis;
- Project to assess: how utility will have to compensate for variations
(e.g., voltage, flicker, frequency fluctuations, etc.) caused by
intermittent generators, determine ancilliary services requirements
and costs for these services.
- D. Koyle reported on the hydraulic oil powered energy (HOPE) wind
technology being developed by Hawaii Pacific Wind:
- First prototype expected by December 2004; and
- Generator and oil pumps located at the base of the HOPE wind turbine.
- C. Framel indicated that $10,000 is available for the HWWG (non-competitive).
- M. Tome reported on the anemometer loan program and 2004 funding:
- Maui Community College may take lead on coordinating and implementing
anemometer loan program; and
- For 2004, some of the $10k could be used to send the anemometer
loan program person(s) for training at WEATS and to fund travel
to the AWEA conference.
- W. Bollmeier inquired on the status of the draft strategic plan and
the HREA-proposed objective of using the HWWG to develop and implement
appropriate policies, rules, and practices to support wind energy in
Hawaii (draft text of Objective #5 distributed to members):
- " Objective #5: using the Energy Efficiency Policy Task Force
as a model, encourage the development and implementation of appropriate
policies, rules and practices to support the increased use of wind
energy in Hawaii.
- Action item #1: provide a forum for discussion fo current
and proposed utility and PUC policies, rules and practices with
respect tot he implementation and operation of existing and
proposed new wind energy facilties.
- Action Item #2: provide a forum for discussion of current
and proposed state policy initiatives to support increased use
of wind energy in Hawaii.
- Action Item #3: seek consensus on policies, rules and practices
and support policy recommendations to the utilities, the PUC,
the counties, and the legislature, as appropriate. "
6. With no additional questions or input, the meeting was adjourned.
