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.
In deregulated markets such as Texas and Maryland, the state government may require the incumbent utility energy provider to allow for unlimited competition within the marketplace, where the consumer is free to choose any electricity provider. Electricity provider switching is only practical if a customer is either buying from a utility or is at the end of a fixed-price contract with a provider.
Residents and businesses that pay directly for their electricity (ratepayers) can use Energy Choice DC to learn more about their purchasing options and the companies that provide electricity aggregation services in the District. Ratepayers connect with a broker who will collect necessary information from them and use that information to seek competitive pricing on electricity, including options for conventional electricity and electricity generated from renewable sources. The broker then presents the negotiated rate to ratepayers, who sign a contract with the selected third-party supplier, for a term of one to three years, and pay a monthly electricity bill based on a consistent rate during that period.
Know that Green Mountain’s cheapest advertised plans are all variable rate plans. “Pollution Free,” “Pollution Free Try 3,” or “SolarSPARC 10 Try 3” all advertise a great initial rate — a full cent below Pennsylvania’s 8.49 cent “price to compare” — but its variable rates means the company can raise them at any time. The two “Try 3” plans just lock in the low introductory rate for three months instead of one. The flipside of fixed rate: Should prices fall, you’ll be locked into a contract with a constant, elevated rate for two more months.
An additional bill was passed in 1999 that helped further establish a competitive electricity market by creating a price floor to prevent established energy providers from underselling emerging providers. In 2002, Texas finalized deregulation when the Public Utility Commission gave ERCOT the responsibility of managing and monitoring the Texas electricity market. The market opened up to around 6 million Texas power customers.
That means that customers in Houston paid an average of $5,500 more for electricity over a 14-year time span beginning in 2002, according to the group that buys electricity on behalf of municipal governments in Texas. The calculation, which uses data from the U.S. Energy Information Administration, assumes monthly electricity use of 1,300 kilowatt hours.
Green Mountain has been behind massive green power projects like supplying the Empire State Building with renewably-offset power, and its nonprofit organization Sun Club provides grants for environmental projects, like Urban REAP (Urban Renewable Energy and Agriculture Project), an innovative community greenhouse that uses solar power, aquaponics, and composting.
