Peak demand times are between 07:30-09:00 and 17:30-19:00 - those are the times people are either getting ready for, or coming home from work.
The Peak District National Park is in England in the United Kingdom
Ben Nivis is the highest peak in the UK
peak is when the demand of electric power is very high, and off peak is when the demand is low
The Lake District

Peak shaving is a process from the electricity business: You shift demand from "peak times" (eg. noon) to times with lower demand (e.g. night) and thus "shave" the peak. You can do that e.g. with devices that do not need to run immediately like washing machines etc...
Demand response is defined as a strategy by energy companies to reduce electricity demands during peak hours. A couple different strategies employed to help this is offering an incentive payment or having lower prices for use during times of non peak use.
Electricity is usually off peak when less people are using it so there is less demand on the power grid. This is typically the middle of the night, and in some cases the middle of the day. As long as you don't mind using your electricity at these times then off-peak electricity is fine, but most people prefer to use electricity in the afternoon, evening, and in the morning, so it tends to be more expensive then. its not an offence to touch a dog.
better prices for off peak purchases takes some of the demand load off the peak times and spreads it out so resources are not overwhelmed.
Too encourage people to use power during of peak periods so as not to overload the system during Peak periods. A good example is of peak hot water. Many people come home from work and have a shower at the same time diner is being prepared and all kinds of apliances get used all at the same time. of peak hot water however gets heated during times when there is not such a heavy load being drawn from the grid. It is also because some of the generation systems used operate continually; it is impractical to shut down a nuclear power station overnight. To make use of the continual power, the power companies try to encourage people to use electricity overnight (usually for storage heating). Supplying in-peak electricity is costly, thus prices are set to incite consumers to shift their load outside peak hours, making off-peak power cheaper. Keep in mind that electricity cannot be stored on a large scale: it must be produced and brought to consumers at the very time it is needed. Here are some of the main reasons for the high cost of in-peak electricity: Transmission bottlenecks: most generating plants are far from cities; if the peak demand is larger than the capacity of transmission lines bringing electricity to cities, suppliers must use closer power generators during peak hours - most often very expensive gas-fired plants. Transmission equipment cost: power lines are very expensive and must be large enough to sustain the maximum peak demand; shifting demand to off-peak hours delays installation of new transmission equipment by electricity suppliers and reduce their operating costs. Off-peak electricity may also be cheaper because some types of generators, like nuclear plants, must produce maximum power 24 hours a day during their entire lifespan; lots of electricity thus gets produced off-peak and must be sold, even at lower prices.
n India the demand of electricity per head is more than generation of electricity.Moreover till December 2011, over 300 million Indian citizens had no access to electricity. With the growing population the demand also increasing. However, generation of electricity is not increasing at that pace. In the picture it is showing a good sign as shortage of power in peak is reducing year by year.
Currently, Iraq's power generation output averages less than 6,000 MW, while the demand is typically more than 10,000 MW.[1] For 2006, the average peak electricity supply was 4,280 MW exceeding demand averaged 8,180 MW by about 3,950 MW. According to U.S. agency officials, demand for electricity has been stimulated by a growing economy and a surge in consumer purchases of appliances and electronics. In addition, electricity is subsidized in Iraq, which leads to increased demand. If the Ministry of Electricity's master plan for 2006 to 2015 to rehabilitate and expand the national grid is implemented, the ministry estimates that Iraq will be able to meet its projected demand for electricity in 2009 [2] http://en.wikipedia.org/wiki/Electricity_in_Iraq
