Those hours when the demand for the service (e.g. electricity, gas) is at the highest and full rates are charged. Such as the sale of electricity during the peak hours. Opposite of off-peak hours
This term does not refer to the amount of energy available when supply is at peak. Instead it refers to the party who supplies energy used to meet peak demand requirements. In other words, a peak supply is a supply of energy which will be used to augment existing energy sources during periods of peak demand
Special tariff offered to consumers who are willing to sign up to a peak shifting / rolling peak scheme, according to which they agree to be cut off from electricity grid during those hours when not enough electricity generation is available – namely during peak hours – in return for a lower electricity tariff during the rest of the year. In Israel the incentive is a 10-15% reduction on the electricity tariff during the remainder of the consumption hours
Natural gas from storage to supplement deliveries during times of peak periods. LNG peak shaving facilities have a regasification unit attached, but may or may not have a liquefaction unit. Facilities without a liquefaction unit depend upon tank trucks to bring LNG from nearby sources.
During peak electricity consumption utilities need to operate more expensive power stations that use more expensive fuels than those used for base load and thus the electricity tariff increases. Peak shaving schemes enables the consumer to cut down his consumption from the grid during these peak times
Using sources of energy, such as natural gas from storage, to supplement the normal amounts delivered to customers during peak-use periods. Using these supplemental sources prevents pipelines from having to expand their delivery facilities just to accommodate short periods of extremely high demand
The accepted defined conditions in the photovoltaic cell industry to define the peak power of a solar sell under Standard test conditions. STC is radiation of 1,000 watt per square meter, a cell temperature of 25 degrees Celsius and air ratio mass of 1.5
A power station operated only during peak demand times. Such stations use more costly fuels and thus the electricity generated from them can be considerably higher than baseload stations
Periods of relatively high energy demand. These periods often occur in daily, weekly, and seasonal patterns; these on-peak periods differ for each individual utility
