Illinois Posts Electric Migration Stats for March

Illinois has posted electric migration statistics for the month of March 2011.

As first reported by Matters last month (5/19), residential migration at Commonwealth Edison as of March 2011 was only 1,862 accounts.

Since the end of March, residential migration at ComEd has surpassed 25,000, as Matters exclusively reported last month when ComEd reported in a discovery response that 26,517 residential customers were served under utility consolidated billing with POR. This total does not include migrated residential customers on dual billing, and a date was not included in the data response excerpted in testimony from Dominion Retail (see 5/24).

Residential migration of 26,517 equals about 0.7% of total distribution accounts.
