Yes, the rate is effective from Jan 1, 2009 but AEP has until the end of the year to collect the difference so I don't think it will affect bills too much? This is from our internal web page: For the average Columbus Southern Power residential customer, implementation of the plan will result in a percentage increase in a customer’s total bill capped at 7 percent in 2009 (approximately $6.97 monthly), and 6 percent each year for 2010 ($6.39 monthly) and 2011 ($6.77 monthly). For the average Ohio Power residential customer, the plan will result in a percentage increase in a customer’s total bill capped at 8 percent in 2009 (approximately $6.55 monthly), 7 percent in 2010 ($6.19 monthly) and 8 percent in 2011 ($7.57 monthly). The 2009 rates are retroactive to Jan. 1. Customers will see the rate increase reflected in their April bill. The company will collect the 2009 revenues in the remaining nine months of the year; consequently, the percentage increase on a customer’s monthly bill will be slightly higher than if the recovery began in January. With the ESP order, the company’s rates continue to be the lowest in the state among investor-owned electric utilities.
