Peak Demand and Electricity Consumption

The analysis covers all of the Smart Grid Investment Grant (SGIG) projects that deployed advanced metering infrastructure (AMI), direct load control programs, time-based rate programs, and consumer information and control technologies, such as in-home displays, web portals, and programmable communicating thermostats to affect the timing and magnitude of the consumption of electricity by customers.

The key analysis question concerned how, and to what extent, these devices and programs resulted in reductions and/or shifts in peak demand and reductions in overall levels of electricity consumption? Analysis objectives included:

  • Evaluating how smart meters, time-based rates, information and education offering such as web-based portals, and customer devices such as programmable controllable thermostats, in-home displays, and direct load control devices:
    • Reduced the level peak demand
    • Shifted peak demand to off-peak periods;
    • Resulted in lower levels of overall electricity consumption.
  • Quantifying how changes in electricity usage patterns and pricing affected customer electricity bills, fuel mixes for electricity generation, and power plant emissions.
