Western Hub is PJM's regional central location. It is the basis for ALL regional nodes. Each nodal price is a differential measured against the Western Hub PJM Locational Marginal Prices (LMP) were calculated for nodes, as: Ridgeline Market – Cloverdale Coastal Plains Market – Delaware Power and Light, Old Dominion Electric Cooperative (DPL-ODEC) Bay Market – Calvert Cliffs Ocean Market - Fentress 9PJM Power Prices (Cents/kWh) - Jan 01 2007 – Mar 24, 2011: PJM Power Prices (Cents/kWh) - Jan 01 2007 – Mar 24, 2011 10Slide 11: Price data covers Jan 01, 2007 – Mar 24, 2011. Seasons are defined as: Fall: Sept-Nov, Winter Dec-Feb, Spring Mar-May, and Sumer June-Aug. On-Peak vs Off-Peak Hours, are defined by PJM, on a wholesale basis, as: Mon-Fri: 0:00 hour through 7:00 hour as off-peak (12 midnight through 7:59 am); Sat-Sun and holidays are off-peak. Mon-Fri: 8:00 hour through 23:00 hour as on-peak (8:00 am through 11:59 pm); Holidays are: New Year's Day - Jan 1*; Memorial Day - last Mon, May; Independence - July 4*; Labor Day - first Mon, Sept; Thanksgiving - fourth Thurs, Nov; Christmas - Dec 25*. * = if this holiday date is Sunday, then take Monday.

RPS can be met thru vast indigenous offshore wind resources in DE, MD, NC & VA: 100 GW in state waters + 148 GW in federal waters [compared to 67 GW installed capacity in the 4 states]. Keeps construction, engineering and maintenance jobs and tax revenues in-State. Unlimited economies of scale benefit offshore - where transport limits land-based turbine size and weight. [ Could 5-10 MW turbines located in large near-shore plants have lower COE than ridgeline plants? ] Revenue to the state from lease of state bottomlands – this revenue could be dedicated to restoring the bays. Complement variable wind resource with low cost natural gas fired electric generating units. Avoid wasted energy and cost associated with lengthy transmission to east coast load centers and support upgrade of local grid systems. 19STATE/FEDERAL POLICIES OVERLOOK COASTAL WIND POWER: STATE/FEDERAL POLICIES OVERLOOK COASTAL WIND POWER Executive and legislative efforts to mandate purchase of wind power are focused on offshore ocean applications (DE, MD, NJ, NC & VA). Large allocation of DOE, DOE and State funding. Renewable Portfolio Standards and Goals (RPS/RPG) allow compliance by purchase of RECs from distant states and by the purchase of Tier II RECs. Consider limiting a portion in-State. Multiple REC allotments limited to offshore wind power ( DE & MD). Allowing a 3x multiplier effectively reduces a 20 percent RPS to 7 percent. Specific Renewable Energy Certificates (REC) requirement (“carve outs”) limited to solar power (MD, others). Federal and state sponsored environmental studies focus on offshore applications; New J ersey has completed baseline environmental studies and MD has data base. Adding this cost to projects is major burden and conflict of interest. Federal sponsored wind resource assessments and economic studies have focused on mid-West and on small scale wind plants. 20Conclusions: Conclusions Wind resource potential and economic value of wind power is being recognized and incentives embodied in some States State regulators need to recognize and monetize total economic and environmental costs of mountain-top coal mining and power plants and long-term value of wind Wind could meet the demand growth and replace output of over-lifetime coal unit retirements (with some natural gas turbine backup) Coastal site wind resources need validation with measurements on tall towers Vast offshore wind resources are available – need to accelerate initial projects Shallow sheltered water deployments can help to reduce cost/risk of offshore wind power 21 You do not have the permission to view this presentation.
