    7. Wind Generation Profile * Kitty Hawk NC Challenge: Moving Wind Benefit to coincide with Dominion’s Peak Load

    8. Solar Generation Challenge: Moving Solar Peak to coincide with economic benefit (PJM LMP Peak)

    9. Solar / Battery Peak ShiftingOptimize Batteries for Peak Benefit Challenge: Moving Solar Peak to coincide with economic benefit (PJM LMP Peak) • Charge battery during off-peak w Solar • Discharge battery during peak • Solar Economic Volume • ≈$30/day Solar only • ≈ $90/day Solar & Battery

    10. Solar Firming/Intermediacy Purpose: To flatten out the solar production throughout the day due to cloud cover by allowing the batteries to fill gaps during short periods of solar production intermediacy. Fast acting relays and controls allows for solar firming

    11. Dominion North Carolina PowerKitty Hawk Microgrid Project • Kitty Hawk Microgrid Research Project details • Located at DNCP district office in Kitty Hawk, North Carolina • Installed “behind-the-meter” • Consists of: • Four microwind turbines (17 kW rated capacity): 3 vertical axis, 1 horizontal axis • Ground-mounted solar PV (6 kW rated capacity) • Lithium-ion battery system (25 kW power/75 kWh capacity) • Existing on-site diesel generator (100 kW) • Sophisticated proprietary control system • Research topics include: • Islanding capability • Intermittency improvement • Wind production vs. solar production in coastal environment • Outage load reduction on existing back-up generator • Peak shaving and peak shifting • Battery storage and degradation • Effect of salt spray on equipment

    12. Dominion Virginia Commonwealth University Microgrid • Partnership between VCU School of Engineering and Dominion • VCU Microgrid details • Located at School of Engineering building • Installed “behind-the-meter” • Consists of: • Small solar PV system • 230 Greenlet Technologies portable voltage monitors • Power Tagging Technologies’ Grid Location Aware • Dominion Voltage Inc.’s EDGE (conservation voltage reduction) • Research topics include: • Collection and analysis of end-use voltage and consumption data • Ability to make real-time energy adjustments to building via voltage optimization and peak demand reduction • Verification of energy/demand savings • Microgrid expected to reduce energy costs by 4%

    13. Other Potential Renewable BenefitsEnabled by technology • T&D Deferral: • Advanced metering has allowed utilities to locate high growth areas where renewable could defer future capital expenditures • Improved Air quality • Take advantage of renewables zero emissions when available • Target non-attainment areas • Future rate increases • Lock in fuel rates, zero fuel cost, non-dispatchable • Islanding capability / Micro-Grid • Outage load reduction on existing diesel back-up generator • Lowers emissions from backup generators • EV / PHEV Charging • Charge vehicles during off peak periods & renewables only • V2G • CPP, TOU, RTP Rates • Interact with smart meters & load in real-time
