Wind Energy
Enabling low-cost and grid-supporting wind energy by joining forces with DOE, industry, and interagency and state partners to advance scientific knowledge and technological innovation.
Research Challenge • Validate multiple wind technologies at scale to achieve an integrated energy system
that can meet the complex energy challenges of the future.
• Develop taller wind turbines with larger rotors to capture greater wind resources at higher elevations and lower the levelized cost of wind energy.
• Develop innovations for offshore wind such as floating platforms, scaling solutions for larger offshore designs, advanced turbine controls, and lightweight drivetrains.
• Optimize total power output across the entirety of a wind plant instead of at the individual-turbine level.
• Enable sustainable manufacturing through new materials and new manufacturing processes. NREL | 8
Project summary
Project objectives
NREL will use the most up-to-date floating offshore wind (OSW) technology information, cost model input assumptions for the unique Hawaiian market, and the Offshore Regional Cost Analyzer (ORCA) model to evaluate floating OSW costs in Hawai’i on a levelized cost of energy (LCOE) basis. NREL will produce visualization materials to convey the current state of floating OSW technology. The OSW cost and visualization information will be integrated into the Engage (heretofore HEVI) / Cambium (heretofore HAVEN) visualization tool.
NREL | 10
Overall project scope
This project will:
• Evaluate the costs of floating offshore wind in the region surrounding O’ahu
• Identify likely technologies, ports, grid connections, and logistics that may be used to build projects
• Produce visualization materials to convey what a floating wind project may look like
• Solicit feedback and information from key Hawaiian stakeholders, and use this information to inform cost modeling where possible
• Provide offshore wind cost information to HECO to assist with IGP planning
This project will not:
• Propose or develop a specific project
• Identify specific areas in which a project will be built
• Conduct detailed environmental, social, cultural, or workforce development studies
• Identify preferred vendors, suppliers, operators, or labor for potential offshore wind projects
• Estimate the impact of offshore wind on ratepayers relative to the current price of electricity
NREL | 11
Today’s goal
• Summarize key project tasks
• Discuss proposed modeling approach
• Solicit feedback, data, and comments on modeling approach
• Next steps:
– Transcribe notes and send to attendees for review and edits
– Incorporate results into cost modeling work as appropriate
– Summarize comments and feedback in final (public) report • Opportunity for some IGP Stakeholder Council members to act
as peer reviewers NREL | 12

Levelized Cost of Energy
where:
LCOE = levelized cost of energy ($/MWh) FCR = fixed charge rate (%/year) CapEx = capital expenditures ($/kW) OpEx = average annual operational expenditures ($/kW/year) AEPnet = net average annual energy production (MWh/year)
LCOE is helpful to compare projects/technologies with different cash flow profiles and over time LCOE does not capture the locational and time value of the generated energy and other services
NREL | 13
Location
Wind speed, water depth, wave height, distance to port and grid infrastructure Technology limitations (e.g., water depth limits)
Cost Modeling Approach
LCOE is calculated as a function of:
Floating technology and plant characteristics
Turbine and substructure characteristics (e.g., turbine rating, power curve) Plant size and turbine spacing
Time
Anticipated learning in supply chain, growth in turbine rating and technology innovation
NREL | 14
Cost Modeling Approach
LCOE is calculated using NREL’s Offshore Regional Cost Analyzer (ORCA) o Deterministic cost model that estimates the LCOE (and its constituent cost and
performance components) of a commercial-scale offshore wind power plant o Used in prior regional cost analyses (e.g., for the U.S. Department of Energy and BOEM)

Hurricane upgrades – background information
• Hawai’i is potentially at risk of hurricanes, which may require hurricane resilient offshore wind systems
– Turbines, platforms, moorings, anchors
• It is not clear if the frequency of major storms is sufficient to justify hurricane-class turbines

Hurricane upgrades – proposed approach
1. Consult with climatologists at NOAA to characterize the risk of major storms in Hawai’i
2. Consult with turbine manufacturers to determine if the storm risk requires a hurricane-class turbine
3. If appropriate, assign cost premiums for relevant components – Determine cost premiums
through industry outreach and rough order of magnitude analysis
Source: National Hurricane Center NREL | 45
Hurricane upgrades – impact on results
• Turbine costs make up 17.2% of LCOE
• Hurricane resilient designs will likely increase turbine cost and LCOE
