SMUD's 2011-2012 Residential Summer Solutions Study investigated the effects of real-time energy data and TOU-CPP rates in the presence of utility or customer controlled thermostat automation. Of the four rate and automation options offered, the TOU-CPP rate + customer-controlled automation provided the greatest savings, with 4% energy savings, daily weekday peak savings of more than 30%, and an average event peak load shed of nearly 60%. Effects of real-time information on these impacts were modest (1-7%), but in many cases statistically significant. On average, customers who signed up for the dynamic TOU-CPP rate saved an average of $145 per summer, while those who chose to remain on the standard tiered rate saved just $40 per summer.
