Special Assistant for Compliance Assurance J.R. Cannon, P.E. Chief of Procurement Don Corrado, Chief of Information Services Ted Hennifer, P.E., General Manager Bruce Husselbee, P.E., Director of Engineering Jennifer Heilman, Commission Secretary David Waltrip, P.E., Director of Operations Jay Bernas, P.E., Chief of Planning and Analysis By Phone: Dr. Jim Pyne, P.E., Chief of Small Communities Nancy Munnyikhuysen, Chief of Public Information From VCERC: Jonathan Miles James Madison University Rick Thomas Timmons Group George Hagerman Virginia Tech Advanced Research Institute Meeting Purpose and Background The meeting purpose was to continue dialogue between the Virginia Coastal Energy Research Consortium (VCERC) and the Hampton Roads Sanitation District (HRSD) about developing a wind turbine test site in the vicinity of the Nansemond Wastewater Treatment Plant. This was a follow-up to previous meetings and discussions regarding the feasibility of HRSD hosting wind turbines at other plant locations, including the Boat Harbor plant in Newport News and the Atlantic plant in south Virginia Beach. Previous interactions also included a site visit to the Nansemond Treatment Plant ( ), transfer of HRSD wind data collected at the Nansemond plant, and coordination associated with logistics of erecting a 50-meter met tower on HRSD Property for additional wind data collection at an elevation closer to turbine hub height. The met tower loan agreement between JMU and HRSD is already in review and details are being finalized. Meeting Discussion and Outcomes 1. After the introduction of the meeting participants, George Hagerman provided background information including the project origin, significant State and Federal milestones along the timeline of development of the offshore wind industry in the Mid-Atlantic, and the identified need for an advanced technology demonstration related to compatibility with operating radar installations. 2. A copy of the VCERC presentation at this meeting is included as an attachment to these minutes. This presentation serves as the Introductory Briefing to the HRSD Quality Steering Team (QST) regarding the project purpose, including information on the wind energy/wastewater treatment plant combination in Atlantic City, NJ, a summary of the current wind resource characterization work in the project vicinity, preliminary estimates of annual energy production, and discussion of next steps.

2 3. HRSD indicated that they have initiated their first alternative energy project, which is a Digester Gas Combined Heat and Power System, at the Atlantic plant. HRSD indicated that they would like the lessons learned during development of the Digester Gas Combined Heat and Power project to be applied to VCERC s analysis of a possible wind turbine at the Nansemond plant, including the following issues: a. Integration and optimal use of the variable wind turbine output with the current energy load profile of the Nansemond treatment plant; b. Projections and uncertainty in wind turbine availability and maintenance costs; and c. HRSD s projected future wholesale cost of power purchased from the utility grid. 4. HRSD wants to continue discussions with VCERC and others in developing a partnership to realize this project, and is considering an internal proposal to include necessary funding into their Capital Improvement Plan Budget to further develop the concept plan, and evaluate the project feasibility. Next Steps 1. JMU will complete the wind resource mapping and validation, covering the area depicted on Slide 13 of the attached presentation and will incorporate the refined data into the economic analysis and estimation of annual energy production by large-rotor turbines suitable for the site. 2. HRSD will provide VCERC with the economic analysis used to evaluate the Atlantic plant Digester Gas Combined Heat and Power System, anticipating that VCERC would use a similar analysis to evaluate wind turbine economic feasibility and payback analysis at the Nansemond plant. 3. HRSD and JMU legal counsel will finalize the 50-meter met tower loan agreement. FINAL Page 2 9 Jan 2012

4 Presentation Overview Meeting Purpose: To explore a partnership between VCERC, HRSD and potentially others including Tidewater Community College and a turbine manufacturer to develop a wind turbine site in the vicinity of the Nansemond WWTP Presentation Outline: - Turbine requirements for large rotor diameter that is suited to relatively low-speed wind resource and evaluation of radar interactions - Jersey Atlantic Wind Farm in Atlantic City, NJ as example of wind energy project at wastewater treatment plant - Wind resource characterization - Preliminary estimates of annual energy production and cost - Q&A, discussion of next steps

5 Technology Demonstration Need for Wind Energy Radar Impact Mitigation Offshore wind power represents the single largest renewable energy resource available to DoD facilities on the U.S. eastern seaboard Can make a substantial contribution towards DOD goal of 20% renewable energy by 2025 and Navy goal of 50% renewable energy by 2020 Need to qualify wind turbines for use in VACAPES Operating Area, and full-scale turbine demonstration in state waters would be a key first step Hampton Roads location would provide potential exposure to a variety of radars (ARSR, Doppler weather, aerial and marine navigation) Full-scale RCS and Doppler measurements to feed into numerical simulations of large offshore project radar signatures to demonstrate signal-processing measures that account for turbine clutter Demonstrate mitigation technologies (coatings, shaping of tower top and nacelle shell structures) Such qualification would have NWS, FAA, DHS, and DOD-wide (not just Navy) implications

10 Jersey Atlantic Wind Farm Operating Facts - Commissioned in Five 1.5 MW General Electric turbines Total project capacity of 7.5 MW at rated wind speed of mph - Total project cost: $12.5 million ($1,670 per kw) - Hub Height: 262 ft Rotor Diameter: 240 ft Total Height: 382 ft - On average, the turbines generate 2.5 MW, and average WWTP usage is 2.3 MW. Under optimal conditions, the turbines generate nearly 5 MW that is sold back to the Grid

11 Jersey Atlantic Wind Farm Business Arrangement - Power purchase agreement: ACUA purchases electricity from a private project developer (Community Energy) at a fixed rate of $ per kilowatt-hour for 20 years - Development and financing: The Jersey-Atlantic Wind Farm is owned by Jersey-Atlantic Wind, LLC a partner with original developer Community Energy, Inc. Just over 20% of the total project cost of $12.5 million was subsidized as follows: Community Energy received a $1.7 million grant from the New Jersey Board of Public Utilities, and a $1.92 million customer supply grant from Atlantic City Electric Co. Private equity investment and debt financing funded the remaining cost. - Savings: ACUA estimates that the energy produced by the wind farm will save the energy equivalent of 11,964 barrels of crude oil per year. The wind farm has also saved ACUA about $2 million in its first four years of operations.

14 Wind Resource Characterization: Measurement Driven Simulation Methodology WAsP (Wind Applications Program) is a simulation modeling program for predicting wind climates, wind resources, and energy production from wind turbines and wind farms. WAsP predictions are driven by actual wind data measured at stations in the same region. WAsP spatially extrapolates measured data across the model domain using a terrain flow model, a roughness change model, and a model for sheltering obstacles.

18 Discussion of Possible Next Steps Questions from HRSD? Our question to HRSD: What does HRSD hope to accomplish with this project what benefits would you like to see realized? Possible next steps: - Step 1: JMU team to complete WAsP wind resource mapping, evaluation of larger-rotor turbines, and economic analysis - Step 2: Develop plans for 50 m met tower installation - Step 3: Develop partnering agreement suitable to all parties - Step 4: Others?
