This interim evaluation report summarizes results from the first year of Lakeland Electric’s two-year 3-Period Time of Use (TOU) program called “Shift-to-Save” (STS). Lakeland Electric has undertaken this study as part of a full system-wide deployment of advanced metering infrastructure funded in part by a grant from the Department of Energy’s Smart Grid Investment Grant (SGIG) Program.
The study objectives are focused on five primary areas:
- Promoting efficiency and reduce electric consumption during peak times;
- Educating customers on pricing options, usage patterns, and peak times to enable them to make changes in consumption behavior;
- Measuring customer satisfaction with different pricing options;
- Determining the value and usefulness of the various pricing plans; and
- Comparing Elect-in and Elect-out enrollment approaches.
Data analysis was conducted to develop 12 different load impact metrics, broken out by the two groups (assigned and voluntary) of participating customers. The study aims to estimate the amount of peak demand savings, the amount of load shifting from on peak or shoulder periods to off peak periods, and the amount of net overall electric usage savings to customers. Other objectives include assessing customer acceptance and retention, customer volunteer rates compared to assigned rates, and customer dropout rates.
