Abstract

This study estimated residential-customer demand response to time-of-use (TOU) rates at Kansas City Power & Light (KCP&L) as part of its Smart Grid Demonstration. The rate was offered to customers in the Green Impact Zone of Kansas City, a geographic area that was the focus of the demonstration. All Green Impact Zone customers were eligible to and able to join TOU because smart meters capable of recording hourly usage were installed prior to 2012.

The TOU rate was constructed to have a rather large difference between peak and off-peak prices compared to other residential TOU rates KCP&L had implemented (and compared to what was used in most other TOU rate pilots), with a peak price of 37.84 cents/kWh and an off-peak price of 6.31 cents/kWh (a six to one price ratio).

Residential customer response to the TOU rates was estimated using a variety of methods. These included an examination of TOU customer load profiles and a formal analytical method in which the effect of TOU rates on customers' usage patterns was quantified as an elasticity of substitution (EOS, which is the percentage of change in the off-peak to peak price ratio).

Method descriptions and a summary of results are presented in this case study.
