Electrical Load _ Normalize supplied load profile to monthly energy usage _ Failure

Dear support team

I would like to use montthly energy data but it simply doesn't work ! I press "edit values" button then i put the values, press ok, but "hourly simulation load profile data" table remains with "zero" values. It's the same to say: "no load data". Thanks for support.

Hi Elton,

To use the "normalize to monthly utility bill" option, you first have to provide a set of hourly data for SAM to normalize. If you don't have a set of hourly load data, you can use one of the files containing computer-generated data that come with SAM.

1. After clicking User Entered Hourly Data, click Edit data.

2. In the Edit Data window, click Import.

3. Navigate to the "samples\Simulated Electric Load Data - Residential" folder in your SAM installation folder ("C:\SAM\2012.5.11\" by default in Windows).

4. Open the text file for a city in a climate zone similar to the one you are modeling. The load profiles are for a residential building.

5. In the Edit Data window, click OK to return to the Electric Load page. You should now see monthly values in the table on the Electric Load page.

6. Check Normalize Supplied Load Profile to Monthly Utility Bill Data.

7. Click Edit Values.

8. Type the monthly values in the table and click OK. You can see the normalized data by clicking Visualize Load Data.

We are aware that requiring hourly load data is a limitation for most people, and are investigating algorithms for synthesizing the hourly data that SAM requires.

In the meantime, you may want to try the EnergyPlus Example File Generator to create your own hourly load data sets.

You may also be able to find some hourly load data on the web. Although the magnitude of the values in these files may not be appropriate for a residential or commercial building load, but the load shapes may be. You can use these files with SAM's normalize function to model a load with a reasonable shape and magnitude for your analysis.

Here are examples of utilities and other organizations who provide free hourly load data that I found by Googling "hourly electric load":

ERCOT: www.ercot.com/gridinfo/load/load_hist/ "

BGE: supplier.bge.com/LoadProfiles_EnergySettlement/historicalloaddata.htm


ISO New England: www.iso-ne.com/markets/hstdata/hourly/index.html

Best regards,

Hi Paul

Thanks a lot for your reply. I have not found a hourly load data file to utilities in my country. I think that would be useful a simplified analysis with monthly average kWh and monthly irradiation (just to a fast project analysis). Anyway, i would like to congratulate the team involved in the project.
