You’ll also see a flat rate and a price per kWh rate for TDU or TDSP (which stand for Transmission and Distribution Utility or Transportation Distribution Service Provider). These are costs that your utility charges for delivering electricity and maintaining power lines. The costs are unique to your local utility and have nothing to do with your electricity provider.
Most of Direct Energy’s plans allow you to earn Plenti points — you get 1,000 as soon as you sign up. That initial windfall is about as good as it gets. You keep accumulating rewards with every payment, but just one point for every dollar you spend on supply charges (what you pay to Direct Energy vs. your EDC — so about two-thirds of your total bill). A Plenti point equates to about one cent, so that 1,000 point bonus works out to $10 when you cash it in with a Plenti merchant (Rite Aid, Macy’s, etc.) You’d have to spend a further $1,000 in supply charges before making off with another $10.00 in Plenti points.
Since the 1990s, many regions have opened up the generation and distribution of electric power to provide a more competitive electricity market. While such markets can be abusively manipulated with consequent adverse price and reliability impact to consumers, generally competitive production of electrical energy leads to worthwhile improvements in efficiency. However, transmission and distribution are harder problems since returns on investment are not as easy to find.
