Context • Electric Vehicles • CT Electric Generation • Peak Rates and Systems • Solar Rates • Strategy – Solar, Bio or Combination • Profit Potential • Timing of Adoption – 98.8% of New by 2031 or 2050 • Modeling • Possible Impacts
Electric Vehicles • 8 Hours to Fully Charge • Distance Exceeds Daily Average of over 75% of U.S. Drivers • All Electric Drive • Gasoline Backup Generator • Can Remember Time Charged • Into Production 2010 • Emerging Competitors May Be Betteri.e. Go Further
CT Electricity Generation Current # in MW • 2 Nuclear 2,035 • 2 Coal-Fired 553 • 26 Oil-Fired 2,487 • 14 Natural Gas 1,463 • 26 Hydro 149 • Solid Waste Fac. 184 • Urgently Need to: • Supply Locally to Meet Peak Demands or • Curtail Peak Demands • Avoid Electric Vehicles Compounding Problems PROBLEM: IF ALL AIRCONDITINERS RUN THEY DEMAND 3+ GW. SUMMER INTERRUPTIBLE POWER PENALTIES COST $700 MILLION IN 2007 ENVIRONMENTAL DIFFUCULTIES IN EXPANDING TRANSMISSION
Peak Rates FERC Finds Elasticities are Small but: • Response Improves with the size of the Spreads Between Peak and Off-Peak Rates • Programmed Cuts in Consumption
Solar Rates Highest cost CT Generator at $1.17/kWh is Deployed Sparingly Any Generation at Lower Cost Is Better
Solar Systems Suitable for Rooftops Now 5 X Sun Experimental @ 10 X Sun
Strategy • Produce at Peak to Reduce Interruptible Charges • Pay Above Peak Rates for Solar • Entice Vehicle Owners to Charge Off-Peak • Get Vehicle Dealers to Invest and Locally Feed the Grid • Consider Rebating Electricity Used to Charge EVs • Maximize Value of Hot Water • Track CO2eq Credits
Making It Pay Without Subsidy • Dealers who Produce Solar Will Be Paid Back within Three years if: • Solar Rates Exceed California’s 41.7 kWh • Solar Rates Exceed Ontario’s 47 kWh and • Environmental TCs are $50/tonne of CO2eq and Dealers Rebate their Customers
Timing of Adoptions • Rapid Adoption: • Growth of 0.02% in year one followed by +20% of previous year’s growth rate. • 98.8% of new vehicles are plug-ins by 2031 and thereafter. • Cumulative vehicle gasoline savings of 29.9 billion gallons. • Cumulative fuel taxes foregone $7.5 billion gross. • CO2eqreductions of 226.7 million tonnes. Slow Adoption: • Growth of 0.02% in year one, 2009, followed by +10% of previous year’s growth rate. • 98.8% of new vehicles are plug-ins by 2050. • Cumulative vehicle gasoline savings of 9.5 billion gallons. • Cumulative fuel taxes foregone $2.4 billion gross. • CO2eq reductions of 72.4 million tonnes
All Scenarios Generate Sufficient to Cover Lost Fuel Tax Revenues
Years to Payout to Equity Holders from Electricity Revenues Only
Conclusions • CT can build on its TOU smart metering to accelerate adoption of electric vehicles • CT can overcome charges for interruptible power and strongly encourage electric vehicle owners to recharge their vehicles at off-peak • Impacts to be positive in employment, labor force, population, personal income • Over-reliance on bio-fuels could erode labor productivity, albeit that issue could be redressed with improved technologies • Increases in personal income taxes under all scenarios were sufficient to offset gasoline sales taxes foregone • Impacts on labor productivity are mixed depending on the relative weights of solar or bio-fuels
Conclusions (Continued) Potential benefits are likely to exceed those modeled since no account has been taken of both erstwhile interruptible power charges and the reduced emissions of CO2eq and particulate matter and the consequential improvements in the quality of life and longevity. CO2eqreductions are 72.4 million tonnes in the slow adoption cases and 226.7 million tonnes in the rapid adoption cases out to 2050.
