Ultimately, any question about the
value of an electricity service
must consider…
“value to whom”?

Annual Use of Supply
Regulatory Assistance Project (RAP)®
• Emissions data – annual, seasonal, hourly
• Comparison to demand data
• Identification of most important days, month, hours
• Identification of which loads can be shifted and
how

Rate design should make the choices the customer makes to minimize their own bill
consistent with the choices they would make to minimize system costs.

Regulatory Assistance Project (RAP)®
• Program design
• Program evaluation
• Ensuring environmental impacts are valued
• Cross-agency collaboration to achieve goals

Conclusion
Regulatory Assistance Project (RAP)®
• Marginal emission info key to maximizing benefits
of flexible load
• State policy, program and regulatory design
influences costs, emissions and who benefits
• Costs and emissions both minimized with right
incentives

Level 2 EV Charging is a Lot Like…
20
An Electric Water Heater!
Regulatory Assistance Project (RAP)®
Water Heater
• 4.4 – 5.5 kW
• 2,000 – 4,000
kWh/year
• Can avoid morning and
early evening peak
charging
• Tank usually covers a
full day’s supply
21
Electric Vehicle
• 3.3 – 6.6 kW
• 2,000 – 4,000
kWh/year
• Can avoid morning
and early evening
peak charging
• Batteries likely equal
a full day’s supply
Really!
