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]
July 2018 data, the latest available, show that the average U.S. price – 13.12 cents per kilowatt hour (kWh) – was down 0.7% compared with a year ago. If you live in Louisiana, you pay the lowest average residential electricity rates of any state in the country – 9.37 cents per kWh. The next lowest rate is in Washington, where residents pay an average of 9.79 cents per kWh.
3.     Customer service:  When the only utility available has lousy customer service, nobody is surprised.  They don’t even pretend to care – they know they have you over a barrel.  With all these new players in town, however, it’s a slap in the face to be treated like royalty until you’ve signed on the dotted line and now they won’t even return your calls or the person on the phone can’t string three English words together or if he does speak English, he’s brand new and panicking trying to pull up your account information.
Prices for any single class of electricity customer can vary by time-of-day called TOU or time of use or by the capacity or nature of the supply circuit (e.g., 5 kW, 12 kW, 18 kW, 24 kW are typical in some of the large developed countries); for industrial customers, single-phase vs. 3-phase, etc. Prices are usually highest for commercial and residential consumers because of the additional costs associated with stepping down their distribution voltage. The price of power for industrial customers is relatively the same as the wholesale price of electricity, because they consume more power at higher voltages. Supplying electricity at transmission-level high voltages is more efficient, and therefore less expensive.
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 that get power from municipal utilities, electric cooperatives and investor-owned utilities that operate outside the state's primary power grid.

There are over 60 different energy suppliers competing for your business on any given day in Texas. Many of these electric companies have websites that are confusing and nearly impossible to navigate, their rates and fees hidden by dense industry jargon and misleading advertising. Who has the spare the time to sort through the choices spread out over all these different sites and companies?
