Ameren Zone II territory dominates
Illinois retail power growth
October 2, 2012

Retail 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 titled "Illinois retail power shopping, August 2012."

          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 territories with shopping in the state (MidAmerican Energy and Mt Carmel are 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 points.

          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.

          One could argue the hottest market in a state is the one with the highest number of new shoppers -- or the one with the highest relative growth in shopping, meaning the one where the largest percentage of eligible shoppers took the plunge and chose a retail supplier.  While sometimes the latter can be misleading, we look at both.


                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 growth.

          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.


                And the winner was?


            The 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 above.

          That gave retailers a 61.51% share of the territory, by far the largest owned by retailers in any territory in the state, and up 592.27% or a staggering 52.628 percentage points.  That was by far the largest relative growth in market share in the period.

          The newness of residential shopping in the state was seen in some astronomical percentages of growth in the year-over-year numbers for several of the territories, such as a 508082.61% growth in shopping in the residential class at Ameren Rate Zone II from the end of August 2011 through the end of August 2012.
