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]
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.
There’s some smart money placing big bets on a rebound for oil. Blackstone Group LP BX, +0.75%  President Hamilton “Tony” James said last month that the company was “scrambling” to invest up to $10 billion in energy companies, according to Bloomberg. Blackstone CEO Stephen Schwarzman said during the company’s earnings call on Jan. 29 that the majority of Blackstone’s energy investments were “oil-price agnostic, including energy-transportation infrastructure where we have off-take agreements, merchant power, renewables and other types of energy-oriented investing.”
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.
