I’m wrapping up my visit to Houston for the Texas Electricity Professionals Association‘s fall conference, and thought I’d share some more information on the state of electricity competition/deregulation. According to Taff Tschamler, executive director at utility consultancy KEMA, the take-up of competitive power offerings has been far greater in the commercial and industrial sectors, which has grown to about 50 percent this year from about 25 percent in 2003. That makes sense, since C&I customers have a lot more incentive to get intimately involved with their power supplies. But only about one-quarter of residential customers now buy power from competitive suppliers Tschamler said — up from about 10 percent in 2003, but still pretty low. Technology that helps homeowners view, price and manage their power consumption in a more real-time way could help open up that market. Texas, with its big push into residential smart metering and a Web portal to bring the data they collect to customers and power sellers alike, will be a good place to test the business propositions behind those home energy management offerings.
