How do you calculate non-coincident peak?

How do you calculate non-coincident peak?

Non-coincident peak is the sum of the individual maximum demands regardless of time of occurrence within a specified period. Rated load factor (RLF) is the ratio of maximum operating demand of a population of equipment to the nameplate power/capacity. It is the ratio of non-coincident peak to theoretical peak.

How is coincident peak demand calculated?

Coincident Peak: Platte River’s peak hour occurred 6 – 7 p.m. on Jan. 5. The customer’s demand for that hour was 163 kW. If this example was for the months of June, July or August, the summer coincident peak demand charge would be 163 kW x $14.50/kW = $2,364.

What is a non-coincident load?

Noncoincident loads are two or more loads that are unlikely to be in use simultaneously, so only the larger of the two loads must be used for the calculation. Careful use of this optional calculation can save customers money and still provide a very safe and effective job.

What is non-coincident?

: the fact or state of not coinciding : lack of coincidence Net metering will simply shift the burden created by noncoincidence of generation and load from the end user to the utility.—

How do you calculate peak load?

Calculate the hours for each month by taking the number of days and multiplying by 24. Multiply the number of hours in each month by the peak demand for the month. Divide the kWh of energy use for the month by the result to get the load factor. Multiply by 100 to get the load factor expressed in percent.

What is a non coincident load give one example?

So a heater and an air conditioner both controlled by the same thermostat would be non-coincidental, because the thermostat will only operate one mode at once. But a water heater and an HVAC system which have completely unrelated control systems, would not count.

What is coincident load?

3.2.1 Coincident demand. The sum of the demands for the same time period. Sometimes also called the simultaneous demand or the diversified demand. The use of the word “diversified” here refers to the fact that the measurements are taken when the various loads are at different percentages of the peak value.

What does coincident demand mean?

3.2.1 Coincident demand. The sum of the demands for the same time period. Sometimes also called the simultaneous demand or the diversified demand.

What is meant by coincidence factor?

A Coincidence Factor is the ratio of the simultaneous maximum demand of a group of electrical appliances or consumers within a specified period.

What does non coincident demand ( NCD ) mean?

Non-coincident Demand (NCD) or Non-coincident Peak Load A customer’s maximum energy demand during any stated period. Customers who use large quantities of electricity may pay a monthly demand charge based on their maximum electric demand during each month.

When does non coincident demand for gas occur?

Non-coincident demand can occur any time, day or night, on-peak, off-peak or super off-peak.

What is the coincidence factor in peak demand?

coincidence factor is 3/7. Some technical references use the term “coincidence factor” to mean the product of rated load factor, demand diversity factor, and coincidence factor. Northeast Energy Efficiency Partnerships (NEEP) defines it as, “The ratio of the average hourly demand during a specified

What does SDG & e non coincident demand charge do?

A component of the Utility Distribution Company Total Rates (UDC), the non-coincident demand charge recovers the costs SDG&E incurs to serve individual customers, such as the cost of transformers located at a customer’s site, sized to a customer’s specific load requirements.
