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.
Unlike with long-term plans, monthly, variable rate (no-contract) plans have no cancellation fees. You won’t have to pay a penalty if you decide to take your business elsewhere because you found a better deal. Plus, you won’t be left paying more than you should if the market rate for energy trends down. However, if the market prices rise, you’ll have to pay more than those who are in-contract.
In summary, fixed-rate plans provide a level of certainty and stability in your energy charge since the price will not fluctuate over the life of your contract. If prices suddenly spike, you are protected because your rate is locked in. The flip side is that if rates drop over the life of your contract, you’ll be stuck paying the higher rate. You can incur steep cancellation fees if you change electricity plans or providers before the end of your contract term.
Electricity pricing (sometimes referred to as electricity tariff or the price of electricity) varies widely from country to country and may vary significantly from locality to locality within a particular country. Many factors go into determining an electricity tariff, such as the price of power generation, government subsidies, local weather patterns, transmission and distribution infrastructure, and industry regulation. “Electricity prices generally reflect the cost to build, finance, maintain, and operate power plants and the electricity grid.” Some utilities are for-profit, and their prices will also include a financial return for shareholders and owners. Electricity tariffs vary by type of customer, typically by residential, commercial, and industrial connections. Electricity price forecasting is the method by which a generator, utility company, or large industrial consumer can predict the wholesale prices of electricity with reasonable accuracy. The cost to supply electricity varies minute by minute.
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.
