The simplest model for day ahead forecasting is to ask each generation source to bid on blocks of generation and choose the cheapest bids. If not enough bids are submitted, the price is increased. If too many bids are submitted the price can reach zero or become negative. The offer price includes the generation cost as well as the transmission cost, along with any profit. Power can be sold or purchased from adjoining power pools.[112][113][114]
Because prices from energy companies in Maryland rise and fall depending on the wholesale price of energy, residents may want a more stable rate for a longer period. A fixed-rate energy plan offers you just that, with a consistent rate for the duration of your agreement at current energy prices – regardless of fluctuations in the energy market. This could mean protection from rate spikes and savings for electric utility customers.
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?
Texas deregulated most of the state's electricity markets in 2002, a move aimed at lowering electricity costs by letting consumers choose their own electric power providers and their own plans. Some parts of Texas continued to be regulated, including those whose power is proved by municipally-owned utilities, electric cooperatives and investor-owned utilities that operate outside the state's primary power grid.
 1.     Contracts:  Before, there were no contracts.  You signed up or you didn’t.  When it’s the only game in town, you have to play by their rules.  Nowadays, you’ll see these ultra-fabulous rates bandied about but it’s only by carefully scrutinizing the fine print that you’ll discover those wonderful rates come with a one-year lock-down or other catches.
As a residential or commercial customer, you’ll enjoy competitive rates, flexible contracts, and personalized plans that give you the power to choose what’s best for you. And we offer no-deposit electricity for well-qualified customers and deposit payment plans for those with less than desirable credit so that switching retail electric providers won’t break the bank.‡ When you switch to Amigo Energy today, you’ll switch on the power of convenience and affordability.
Excessive Total Harmonic Distortions (THD) and not unity Power Factor (PF) is costly at every level of the electricity market. Cost of PF and THD impact is difficult to estimate, but both can potentially cause heat, vibrations, malfunctioning and even meltdowns. Power factor is the ratio of real to apparent power in a power system. Drawing more current results in a lower power factor. Larger currents require costlier infrastructure to minimize power loss, so consumers with low power factors get charged a higher electricity rate by their utility.[130] True power factor is made of displacement power factor and THD. Power quality is typically monitored at the transmission level. A spectrum of compensation devices[131] mitigate bad outcomes, but improvements can be achieved only with real-time correction devices (old style switching type,[132] modern low-speed DSP driven[133] and near real-time[134]). Most modern devices reduce problems, while maintaining return on investment and significant reduction of ground currents. Power quality problems can cause erroneous responses from many kinds of analog and digital equipment, where the response could be unpredictable.

Consumers in Houston, Dallas, Fort Worth and Corpus Christi were promised bargains on electricity when the Texas Legislature deregulated the electricity market. But 16 years later they're still paying more for electricity than their counterparts in cities Texas lawmakers exempted from deregulation such as Austin and San Antonio, according to the Texas Coalition for Affordable Power which analyzed federal electricity pricing data.
