To be clear, no matter fuel portfolio of the plan you choose, your electricity’s make-up will be identical to your neighbors’. Depending on where you live, that could a mix of renewable and fossil fuels. Certificates offset your electricity use by putting an equal amount of clean energy into the electricity grid. If a plan is 100% renewable, that means it’s 100% offset with certificates.
With the exception of Hillsboro, the incorporated towns in Loudoun County provide water and sewer service to residents of the towns and some outlying areas.  Rates vary between towns and between in-town and out-of-town service areas.  It is best to check rates before the first water bill arrives.  Town residents with questions or problems regarding these services should contact their town government.
Customers can find deals in competitive electricity markets if they take the time and effort to look at web sites such as powertochoose.org, the official comparison shopping site of the Public Utility Commission. The study cited a PUC survey of retail electricity offerings in Houston that showed nine deals in March that were lower than the regulated price of electricity in San Antonio.
As an Exelon company, Constellation Energy is part of one of the biggest — and historically most polluting — corporations in North America. Given Exelon’s vast production energy, ranking on the PERI Toxic 100 list is perhaps not that surprising. The good news is that Exelon is upfront about its room for eco-friendly improvement and make it easy for Constellation customers to go green, too.
Not all areas of Loudoun County have access to all providers.  Some areas, particularly in the rural parts of western Loudoun, must rely on wireless and/or satellite for their Internet and television services.  And, depending upon the topography, even these may be spotty or completely unavailable.  Other communities, such as Broadlands and Lansdowne, may be tied to a particular provider. The individual service providers can confirm whether or not they provide service to a particular address.

Prepaid electricity plans are yet another option available to Texas customers. Prepaid plans let you avoid credit checks and deposits by pre-paying for your electricity. Prepaid electricity plans typically do not have a fixed duration and operate on a pay-as-you-go basis. Shopping for prepaid electricity can often yield relatively cheap electricity with no deposit. See Prepaid Electricity: Is It Right For Me? for more.
Variable rate plans are always month-to-month, save for three-month intro specials in which your rate stays the same for those early months. Fixed rate plans, on the other hand, are available for periods ranging from six to 36 months. The contract lengths, and how that length influences the price per kWh rate, varies enormously from company to company. Some companies offer lower rates when you enroll for longer periods. Others raise the rate slightly. The competing rationale: You will be paying them for longer so you get a break, or you have that price locked in when energy rates inevitably rise. One rule of thumb — the longer the contract, the higher the cancellation fee.

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.


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.
