is electricity cheaper at night?
The answer is yes, for some people, depending on the electirc company or coop they purchase from. Often companies that acquire their power from hydro electric sources offer a discounted rate (expecially in rural areas) for use of electricity during off peak hours.\n\nHydro electric power is much less flexible than other sources (such as opposed to coal or oil fired) when it comes to output.  You can't simply shut the dam off.  This means a consistant production of electricity every hour of the day...  Unfortunately this results in the need to produce more power during peak times, and an excess of power during off hours.  More power is supplied by burning fossil fuels to produce energy, however any excess power that is produced is lost, as we have no efficient way to store electricity, expecially in large amounts.  So by offering discounted rates for usage in non peak times, Electric companies spend less on fossil fuels during peak hours, and make money on electricity that would normally go to waste during off hours...\n\nFor an example of a company that offers such services check out Utah Power.... here is the link to "Tim of Day" rate plan for their service area in Idaho... http://www.utahpower.net/Article/Article51343.html
