TDU Delivery Charge: TDU stands for transmission and delivery utility — in other words, the utility company in your area that is actually piping the energy from the power generation companies into your home. (Remember, REPs in Texas are just the middleman.) The TDU delivery charge is set by the utility and is consistent from plan to plan and provider to provider within its service areas. For example, AEP , the TDU for Corpus Christi, charges the same delivery fee for all TXU, Direct Energy, and Reliant plans. You don't typically get a choice in utility company, and therefore, these fees are pretty much unavoidable, non-negotiable, and won't factor into choosing an electricity plan or provider.
According to a typical economic theory, prices are optimally determined in a fair and transparent market, and not by a political or academic body. In deregulation of electricity markets, one immediate concern with pricing is that incumbent electricity providers would undercut the prices of new entrants, preventing competition and perpetuating the existing monopoly of providers. Thus, the SB7 bill introduced a phase-in period during which a price floor would be established (for incumbent electricity companies) to prevent this predatory practice, allowing new market entrants to become established. New market entrants could charge a price below the price to beat, but incumbents could not. This period was to last from 2002 to January 1, 2007. As of 2007 Texas investor owned utility affiliates no longer have price to beat tariffs.
For example, shoppers for Texas electricity plans in the 77494 ZIP code in Katy, TX, could find 12-month plans for 6.8 cents/kWh in February; by June, electricity rates had increased 27 percent to 9.3 cents/kWh. As of early September, 12-month plans were up again, to 9.9 cents/kWh – a 6.5 percent hike from June and a 46 percent increase just since February.
Since the Texas electricity market opened to competition in 2002, many Texas residents have had the opportunity to choose their own electricity provider. Instead of relying on their local utility to provide them with electricity, most Texans can choose from a variety of competitive providers, allowing them to shop around for the perfect electricity plan for their homes and lifestyles.
One of the benchmarks of a successful free market is the range of choice provided to customers. Choice can be viewed both in terms of the number of firms active in the market as well as the variety of products those firms offer to consumers. In the first decade of retail electric deregulation in Texas, the market experienced dramatic changes in both metrics. In 2002, residential customers in the Dallas-Fort area could choose between 10 retail electric providers offers a total of 11 price plans. By the end of 2012, there were 45 retail electric providers offering 258 different price plans to residential customers in that market. Similar increases in the number of retail electric providers and available plans have been realized in other deregulated electricity market areas with the state.
Utility companies are responsible for transmission and delivery of electricity even in energy deregulated parts of Texas and should be contacted in the event of a power outage. Your retail energy supplier may provide you competitive electric rates or exceptional customer service, but they cannot repair power lines or restore your service.
