Illinois Shopping Growth Again Spikes as Aggregations Begin Flow

Illinois saw the number of residential electric shoppers grow by 150,000 accounts from January 31 to February 28 as more opt-out aggregations from the November ballot began billing customers on competitive supply.

The Plug-In Illinois site has been updated with the number of residential accounts migrated to (and billed on) competitive supply as of February 28, 2013. As has been noted previously, the ICC migration statistics discussed in this story reflect 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.

Specifically, the growth in the number of residential electric accounts on competitive supply was as follows from January 31, 2013 to February 28, 2013:

ComEd:                         34,326
Rate Zone I, AmerenCIPS:       35,131
Rate Zone II, AmerenCILCO:      7,829
Rate Zone III, AmerenIP:       68,885

The ComEd growth was in line with the January growth, but the growth at Ameren, especially Rate Zones I & III, was significantly higher, indicating aggregation customers which completed their first billing cycle on competitive supply.

The total number of residential customers on competitive supply at each utility as of February 28 was:

ComEd:                      1,468,000
Rate Zone I, AmerenCIPS:      108,000
Rate Zone II, AmerenCILCO:    136,000
Rate Zone III, AmerenIP:      227,000
