*losscode <> “T” (ESI ID is connected at a distribution voltage)

*mrecode <> “65” (ESI ID is read by a TDSP)

*status <> “I” (ESI ID is active or de-energized)

*Pull all interval data for identified ESI IDs from 1/1/2002 to present

*Calculate monthly max kW values

*Determine if ESI ID monthly max values exceed a specified threshold by occurring twice in a twelve month period
