Illinois Residential Electric Shoppers Exceed 1 Million

The number of residential electric customers in Illinois who have completed at least one billing cycle on competitive supply topped 1 million for the first time in August, according to a snapshot of statistics posted by the Illinois Commerce Commission.

The Plug-In Illinois site has been updated with the number of residential accounts migrated to (and billed on) competitive supply as of August 31. More detailed statistics (such as % of customers switched and load data), and statistics for non-residential classes, has not yet been posted as of press time.

As previously noted, the ICC migration statistics discussed below show customers who have switched to a competitive supplier and have completed at least one billing cycle on competitive supply. Accordingly, the data lags completed enrollments.

According to the Plug-In Illinois report, nearly 713,000 ComEd residential customers had completed at least one billing cycle on competitive supply as of August 31, 2012, compared with 527,000 as of July 31; 437,000 as of June 30, 2012; and 406,000 as of May 31, 2012.
