Continued Tracking of Changes in the Load
Updated: May 5, 2020
April 30, 2020
We are continuing to track “What is the change in the load?” due to the various shelter-in-place orders going out. We have had many videoconferences with our LDC partners.
What are we seeing across various customer bases?
Here is an update to two charts we posted previously. The first is the time-series of percent load changes due to the pandemic for 77 customer bases from several LDCs. These 77 customer bases account for 12.8% of the United States’ residential, commercial, and industrial usage (according to EIA). Some are large, some are small, drawn from about 20 states. Some are system or core customers, some include transports, some just transport. The heavy black line is the daily mean. The heavy green line is the daily weighted mean, taking into account the sizes of the different operating areas.
This second chart shows the histograms of the percent residuals on Tuesdays since March 3, 2020. This is another way to look at the mean, the weighted mean, and the spread of the load reductions over time. Different customer bases are affected differently.
An offer to GasDay users: We can generate the Load Analysis charts in previous posts and the charts above in your operating areas. Please just reach out to us with your request. Also, we are happy to update these charts as needed.
