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.
2. Fraud: Too many people have been victimized by glib sales reps with promises of cheap electricity flowing in an unending stream only to discover that, as is so often true, “it ain’t necessarily so”. They’ve been locked into unwanted term contracts or there’s a catch – some utilities will give you the great rate only if you meet a usage minimum; basically, the “rate” is, in actuality, a “bulk purchase” discounted fee – or they paid a deposit never to hear from the rep again.
OPEC nations, along with Russia and Mexico, have refused to cut production, which is their traditional tool to prop up oil prices, out of fear of losing market share to the U.S., which has transformed the international oil market by greatly expanding hydraulic fracturing over the past decade. And U.S. producers might not lower production as quickly as some investors expect because of the significant improvement in the efficiency of horizontal fracturing wells.
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. Curtailment could potentially significantly impact solar power’s economic and environmental benefits at greater PV penetration levels. Allocation is done by bidding.
There was a time when electricity was electricity. Like so many other places around America, in Houston, electricity didn’t mean “cheap electricity”. But you moved into your home and you called the utility and they turned on the power and the bill came in and you paid it every month. Oh, sure, you might grumble at the amount but then you’d go around and yell at the kids for leaving the lights on and the TV blaring with nobody in the room or maybe you’d look into buying more energy-efficient appliances. When it came down to it, the Bill was the Bill. Either you paid the bill or you ate dry packet meals, had cold showers, and watched TV by peering through the neighbor’s window after dark (preferably once they’d turned the TV on). What’s that? You want cheap electricity? Sure thing: call 1-800-WHO-CARES any time during regular business hours of 2:17am to 3:04am Sundays only.
Short-term prices are impacted the most by weather. Demand due to heating in the winter and cooling in the summer are the main drivers for seasonal price spikes. In 2017, the United States is scheduled to add 13 GW of natural-gas fired generation to its capacity. Additional natural-gas fired capacity is driving down the price of electricity, and increasing demand.
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.
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.
