The world's first public electricity supply was provided in late 1881, when the streets of the Surrey town of Godalming in the UK were lit with electric light. This system was powered from a water wheel on the River Wey, which drove a Siemens alternator that supplied a number of arc lamps within the town. This supply scheme also provided electricity to a number of shops and premises to light 34 incandescent Swan light bulbs.
The consumer has the choice between buying from their local utility (Local Distribution Company - LDC) or from one of the deregulated suppliers. There is a large range of contract options from a variable price to 1,3 or 5 year fixed prices. Electricity provider switching is difficult once the consumer is in one of these contracts, unless they are close to the end of a fixed price contract. However, as of January 2010 there is a maximum termination penalty allowed.[2]
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.

With moderate fluctuations taken into account, the variable plans is still cheaper. Our bill is approximately $10 more in the winter, but we’d still save $138 over the course of a year. It’s more a question of whether you can roll with the punches of an unpredictable rate, or would sleep easier knowing your bill is going to look the same month after month.

In deregulated states, electricity providers simply can't do business like that because consumers like you are demanding energy from renewable sources. Threats of global warming are too terrible to be irresponsible with our energy sources anymore. As a result, each electric company is pushing forward to find renewable energy sources that are cheaper, cleaner, and more reliable than older forms of energy.

In some states, utilities can also generate and sell electricity, but customers aren’t forced to buy the electricity from the utility company. They may choose from either the utility or available electricity providers. Before signing up for electricity service, we recommend checking the local utility’s electricity supply rate by checking their rates online or contacting them directly.

Twenty-nine states have deregulated electricity, natural gas or both. That allows you to shop for the supply portion of your bill from alternative providers who may offer rates lower than the default supplier – usually a utility. Delivery services and billing will remain the responsibility of the local utility as they own the power lines and wires that keep the lights on.
Where should you shop for electricity? Houstonians have the power to choose from an overwhelming variety of energy suppliers, plans, and options. If you live in the Houston metro area and your local electric utility is CenterPoint, over 50 different retail electricity providers currently offer electricity plans in your area. Each of these electricity providers offer sites, tools, and information on how to switch plans and providers. However, their information is often filled with electricity rates that are difficult to compare because of things like introductory rates, bill credits, narrow usage levels, unexpected fees, and legalese buried in the EFLs. Fortunately, Houston homes and businesses have electricity shopping options that make the process much simpler.

Of course, choosing a new electricity supplier or natural gas supplier does not mean you are replacing your utility. Your utility will still deliver whatever energy supply you choose, safely and reliably. Since your utility company depends on where you live, you don't have to worry about choosing a utility company. In general, utilities are responsible for maintaining the energy infrastructure. If you experience a power outage or see a downed power line, call your utility company. These are listed in the Utility Companies column below.
