The two most common distinctions between customer classes are load size and usage profile. In many cases, time-of-use (TOU) and load factor are more significant factors than load size. Contribution to peak-load is an extremely important factor in determining customer rate class. Consumer loads may be characterized as peak, off-peak, baseload, and seasonal. Utilities rate each load differently, because each has different implications for a power system.
Wind and solar power are non-dispatchable. Such power is normally sold before any other bids, at a pre-determined rate for each supplier. Any excess is sold to another grid operator, or stored, using pumped-storage hydroelectricity, or in the worst case, curtailed.[116] Curtailment could potentially significantly impact solar power’s economic and environmental benefits at greater PV penetration levels.[117] Allocation is done by bidding.[118]
Net metering is another billing mechanism that supports the development of renewable power generation, specifically, solar power. The mechanism credits solar energy system owners for the electricity their system adds to the grid. Residential customers with rooftop PV system will typically generate more electricity than their home consumes during daylight hours, so net metering is particularly advantageous. During this time where generation is greater than consumption, the home’s electricity meter will run backwards to provide a credit on the homeowner’s electricity bill.[3]
To skirt the late summer electricity rate hikes, a little bit of planning can really pay off. Try to avoid signing new long-term electricity contracts in late summer. While it may be impossible to escape signing a new electricity contract if you’re moving during that time, just know that a short-term plan may make more sense until the rates go back down in the fall.  That way you’re not stuck paying a premium rate for an entire year or more.

Keeping on top:  With deregulation, a whole host of electric resellers jumped into the market because there’s a whole lot of electricity to sell:  if Texas were a country, it’d be the 11th largest electricity consumer in the world!  Just by itself, it uses as much electricity as Spain or Great Britain!  That means there’s a whole lot of information you have to find, absorb, and process to make sure you’re getting the best rate for your needs.

Utilities, or energy companies, in Maryland offer customers information to know how much they are spending on electric supply each month. Baltimore Gas & Electric Co., for example, provides a tool known as the Standard Offer Service, which shows customers how much they can expect to pay for energy supply each month. Current supply rates show that BGE customers will pay 8.225 cents per kilowatt hour (kWh)., as of mid-May, offers a 36-month plan that could save 13 percent on that rate now.
If you live in the greater Houston area, there are over 60 different energy suppliers competing for your business. Many of these providers have websites that are confusing and difficult to navigate, their rates buried in misleading advertising and dense jargon. Who has the time to sort through and keep track of options across all these different sites?
Fixed-rate, long-term (contract) plans provide stability in electricity rates. If market energy costs suddenly trend upward where you live, you can rest assured that you won’t have to pay more out of pocket. However, if you want to switch to a different, lower-cost plan before the end of the contract term, you’ll likely have to pay a cancellation or early termination fee.
