On the maximum day, the hour with the greatest demand is called the Peak Hourly Demand [see figure below, and Figure 4. Operational (equalization) demand is a flow rate that is the difference between peak hour demand and maximum day demand. This process allows the load curve to flatten and can offset/slow down the investment required in additional capacity to meet peak electricity and water demand. driven peak demand levels and does not attempt to determine potential load curtailment risks due to transmission line outages. 85% in the same period. two hot water storage tanks. The problem with peak demand is this steepness: the top 2 gigawatts, 15% of total. Domestic water supplies shall be designed to produce 125 percent of the maximum day demand. 8 x average daily demand)/24 = 2. These retirement jobs are often filled by people who are age 62 or older. That’s the word from the Brattle Group, in a report, “The National Potential for Load. Peak hour demands typically occur during the morning hours. Demand forecasting is also an important factor for the management of water consumption, especially when you intend to create or expand a urban water supply system. For residential area, Time consumption factor is 24/18. The water is supplied by pumping directly and the pumps and distribution system must be designed to meet the peak demand.
