TheDailyBeast review of regulatory filings found at least 16 utilities covering 6.1 million customers are seeking rate hikes of 5 percent or more. Almost half of those want increases of 10 percent or more. And several more utilities already have received approval for large increases. For instance, close to three million customers in parts of Virginia, Kentucky, Ohio, and West Virginia that get their electricity from American Electric Power have seen their rates increase between 48 and 88 percent over the last few years. Those rates are expected to rise an additional 10 to 35 percent in the next three years. The reason? AEP officials are quick to blame environmental regulations that they say are going to cost the company $8 billion in compliance and upgrades.
