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.
Customers can find deals in competitive electricity markets if they take the time and effort to look at web sites such as powertochoose.org, the official comparison shopping site of the Public Utility Commission. The study cited a PUC survey of retail electricity offerings in Houston that showed nine deals in March that were lower than the regulated price of electricity in San Antonio.
Every single energy supplier in the UK is regulated by Ofgem, the industry regulator. This means that the smaller, lesser-known companies have to follow exactly the same rules as the bigger, more established ones. If a company goes bust, you’ll be covered by Ofgem – they’ll ensure your supply isn’t cut off, and they’ll appoint a new supplier to take over your tariff.
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]

No. When you’ve chosen a new deal, your new supplier will handle the switching process. They’ll contact you to let you know what date you’ll be transferred over, and they’ll contact you around the switching date to ask for a meter reading. They’ll pass this on to your old supplier so they can send you a final bill. You don’t need to contact your old supplier, as the new supplier will handle everything for you.
A feed-in tariff (FIT) is an energy-supply policy that supports the development of renewable power generation. FITs give financial benefits to renewable power producers. In the United States, FIT policies guarantee that eligible renewable generators will have their electricity purchased by their utility.[2] The FIT contract contains a guaranteed period of time (usually 15–20 years) that payments in dollars per kilowatt hour ($/kWh) will be made for the full output of the system.
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 rates for companies vary greatly by industry and function. Although homes come in all shapes and sizes, businesses have larger variations with diverse needs – from industrial buildings to mom-and-pop businesses. In July, for example, the average business in Oregon paid 9.41 cents per kWh. With this number, we can deduce that on average companies in the state paid about $591 that month for electricity.    
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.
