Base Rates | Trackers | Sales Taxes


Vectren’s electric utility serves six southwestern Indiana counties. Its residential electric rates rank highest among the electric utilities the IURC regulates as of July 1, 2016.

Major components in a typical electric bill include base rates, trackers, and sales taxes.

Base Rates

Base rates cover most of a utility’s operating and maintenance costs. They make up nearly 98 percent of a typical Vectren residential electric bill.

Vectren’s electric base rates were approved in April 2011. The OUCC’s news release outlines the order’s consumer protections.

In addition to base rates, Vectren and other electric utilities recover and credit separate, specific costs through rate adjustment mechanisms known as "trackers." The OUCC reviews all tracker rate adjustments in IURC cases on a regular basis.

Vectren is authorized to use 5 electric trackers. They make up about 2 percent of a residential customer’s typical bill.
