# Create hourly electrical demand data

• A87
In summary, the conversation discusses the possibility of estimating hourly electricity demand data based on daily peak load and total electrical consumption. The expert explains that this is not possible due to the limited information provided by these integral or point quantities. They suggest measuring the data or using industry research and statistics as a more accurate approach.

Hi

Is there a way to create/estimate the hourly electricity demand data of a system by just knowing the daily peak load (and at what time this happens)and the total electrical consumption per day?

A good estimation based on a statistical technique sounds like a good start!

Cheers

Short answer: no. These are integral or point quantities that by definition have thrown away most of the information of the original data set. You can't make information out of nothing, which is what getting hourly data from a single integral point (an average), or hour (peak), is really trying to do. Akin to trying to go faster than light - the universe won't allow it.

You might be able to "guess" that there is some type of daily cycle but it would really depend on specifics of consumption. You might guess the peak would be in the mid afternoon (at least during the summer in a hotter climate) because of A/C but in a winter climate, that might instead be at a very different time of day. Also depends on if the home/building is occupied at certain hours and by how many.

The only sure way is to measure it.

Or look for industry research and statistics and presume them as typical. http://my.epri.com/" are the logical starting points for this but it probably won't be for free. But they both have a handful of free documents that might help.

## 1. What is hourly electrical demand data?

Hourly electrical demand data refers to the amount of electricity used within a specific time period, typically an hour. It is measured in kilowatt-hours (kWh) and is often used by utility companies to track and manage energy consumption.

## 2. Why is it important to create hourly electrical demand data?

Creating hourly electrical demand data is important for understanding energy usage patterns and identifying peak demand periods. This information can help utility companies plan and allocate resources more efficiently, as well as inform energy conservation efforts.

## 3. How is hourly electrical demand data collected?

Hourly electrical demand data is collected through the use of smart meters, which record energy usage at regular intervals and transmit the data to the utility company. This data can also be collected manually by reading the meter at specific times.

## 4. What factors can affect hourly electrical demand data?

There are several factors that can affect hourly electrical demand data, including weather conditions, time of day, and consumer behavior. For example, hot weather can lead to increased energy usage for air conditioning, while shifts in consumer behavior such as turning off lights and appliances can reduce demand.

## 5. How can hourly electrical demand data be used?

Hourly electrical demand data can be used for various purposes, including pricing electricity, managing peak demand, and identifying areas for energy efficiency improvements. This data can also be used to monitor changes in energy usage over time and inform long-term energy planning.
