Industrial Rates not Shown for Commercial URDB Downloads

[cpaulgilman]

For a Commercial case, the OpenEI Utility Rate Database window does not list rates classified in the URDB as Sector = Industrial.

In SAM, it is appropriate to use the Commercial financial model for a behind-the-meter system for an industrial building or facility.

For example, the Madison Gas and Electric Cg-2 and Cg-4 rates are both described as "Commercial and Industrial" rates, but for the Sector field, the URDB assigns "Industrial" to Cg-2 and "Commercial" to Cg-4.

Cg-2: https://apps.openei.org/IURDB/rate/view/648732db415f0823850590ba

Cg-4: https://apps.openei.org/IURDB/rate/view/648732db415f0823850590ba

The result is that in SAM, the Cg-2 rate is not listed for a commercial case:

A workaround is to choose All to show the Cg-2 rate:

To Reproduce

1. Create a Commercial case.
2. On the Electricity Rates page, click Search for rates.
3. Filter the list of utilities for "MGE".
4. Note the list of available rates does not include Cg-2.
