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.[121] 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.
Electric bills for customers in the Houston area can more than double in summer months, mainly because air conditioning. Not coincidentally, electric rates also rise in the summer months because of this increase in demand. The most dramatic rate increases occur in month-to-month plans, but electric rates do increase across the board for all fixed-rate contract lengths.
Snowpack, streamflows, seasonality, salmon, etc. all affect the amount of water that can flow through a dam at any given time. Forecasting these variables predicts the available potential energy for a dam for a given period.[124] Some regions such as the Egypt, China and the Pacific Northwest get significant generation from hydroelectric dams. In 2015, SAIDI and SAIFI more than doubled from the previous year in Zambia due to low water reserves in their hydroelectric dams caused by insufficient rainfall.[125]

Power generation projects, which have to sell their power to these bankrupt utilities, require creative financing structures to get around these problems. In a bid to reduce their risk when financing these projects, bankers employ financial tools like put call options agreement or World Bank partial risk guarantees. The problem is these tools add complexity and cost which end up being passed on to the end-user or worsen the financial state of the power utility.
While there is a very strong argument for providing cheap, subsidized power for the poorest in society, this should be done in a way that limits subsidies to the really deserving and the system as a whole needs to be able to charge tariffs that on average cover all costs. If this doesn’t happen then all manner of bad things will follow. As you might guess prices have been set too low by African governments. These subsidies have also been made too widely available, benefitting the elite and middle classes more than the poor (who, not having good access to the grid in the first place, don’t have ready access to these subsidies).

The average home in the U.S. consumes 897 kilowatt hours (kWh) of electricity per month. Bills vary by state and region, as cost per kWh differs. To estimate average energy bills, multiply the average home’s electricity usage (897 kWh) by the cost per kWh in your state for that month. For example, the average cost per kWh in July for Colorado homes was 12.67 cents, which amounts to an average bill of about $113.65 (12.67 cents x 897 kWh) that month.
Electricity cannot be stored as easily as gas, it is produced at the exact moment of demand. All of the factors of supply and demand will therefore have an immediate impact on the price of electricity on the spot market. In addition to production costs, electricity prices are set by supply and demand.[120] However, some fundamental drivers are the most likely to be considered.

On the other hand, month-to-month variable rate (no-contract) plans don’t have cancellation fees. You won’t be penalized if you find a better deal elsewhere and want to make another switch.  And, you won’t be stuck paying more than you should be if the market rate for electricity trends down.  But, if it goes up, you’ll be paying more than your in-contract neighbors, and you’ll likely want to shop around again for a better deal.
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]
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.
