Ameren Zone II territory dominates
Illinois retail power growth
power shopping grew 7.82% from April, the last month we reported, to August, the
latest month the ICC published results for. That percentage represented a shopper
tally that grew by 44,636 to end at 615,235 out of 5,088,685 utility customers
eligible to shop for power.
That result gave retailers a 12.09% share of the market statewide, up
8.01% or 0.896 percentage points from April. These results were published by the ICC
and presented with retailer market share and change analysis including
year-over-year results on the Restructuring Today website on a page

Shopping grew 9.83% in the residential class statewide, adding 40,453 to
end at 451,850 eligible utility customers.
That gave retailers a 9.90% share of the class across the six utility

reported by the ICC among the six but have no shoppers).
Retailer share of the residential class was up 10.04% or 0.904 percentage
The C&I class saw shopping grow 2.63%, adding 4,183 to reach 163,385
out of 525,804 eligible shoppers.
That gave retailers a 31.07% share of the class statewide, up 2.64% or
0.8 percentage points.

Which one added most?
The utility territory that saw the most new shoppers was Commonwealth
Edison's with 373,645 in the four months being reported. That was not the highest relative growth
but represented 338,422 new residential and 35,223 new C&I accounts that
migrated to retailers from the incumbent utilities.
The utility had by far the most eligible shoppers with 3,759,349
territory-wide, but the size of the market does not necessarily predict
Ameren Rate Zone II added 112,073 new shoppers -- it had 212,967 eligible
to shop, and Ameren Rate Zone III with over double the eligible accounts at
613,013 added only 87,972. Ameren
Rate Zone I added 36,908 and had 383,156 eligible to shop.
That takes us to the leaders in relative growth.

territory with the highest relative growth in shopping was Ameren Rate Zone II,
up 592.01% by adding the 112,073 new shoppers reported above to the previous
18,931 to reach 131,004 shoppers out of those 212,967 eligible reported
That gave retailers a 61.51% share of the territory, by far the largest
