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.
Every state that is deregulated requires their electricity providers to be licensed or certified by the state in order to sell electricity. Your state’s public utility commission website keeps an up to date list of these electricity providers so that you can be certain that you are purchasing electricity from an authorized electricity provider. All of the electricity providers represented on ElectricityPlans.com are authorized electricity providers in the respective states where they do business.
