Load Disaggregation using CEEI Data

[pmcwhannel]

Before using the CEEI data to disaggregate the BC Hydro historical hourly load data (A). It's important to ensure the data aligns, the CEEI electrical load data is delineated between utilities managing the data. The CEEI load is provided in KW-hr and provides the annual electricity consumption measured by each of the utilities in BC.

When I looked into comparing these values for 2020. I noticed the annual load based on BC Hydro hourly load was only ~77% the amount as the CEEI for the same year. There are many things that could cause this issue, however, it currently remains unclear. Some ideas are below:

• The CEEI load consumption is measured at the substation level therefore losses of the distribution are not seen, therefore, load would be higher.
• In the CEEI dataset there are 2 sectors: 1) Residential (Res) and 2) Commercial small & Small-Medium Industrial (CSMI), it's not clear where large industrial fits into this. However, it would be expected if large industrial were missing from CEEI then CEEI should be smaller than BC Hydro Hourly. We see the opposite issue.
