Abstract
More homes across the United States have air conditioning than ever before. The
saturation of residential AC has risen dramatically over the last several
years, from 56% in 1978 to over 75% in 2001.
In this report, we examine this trend and address a number of key questions:
How is increasing AC saturation affecting typical residential load shapes and
system load shapes? How do those altered load shapes in turn affect
distribution facilities, load forecasting, and cost allocation and pricing?
Finally, we look at ways that utilities are or could be dealing with the
situation, including promoting demand response programs, technology changes,
and efficiency standards.
