Just completed a meter testing case with Westar Energy (now Evergy Kansas Central) that cost my client $18,000 in overbilling. The meter was running 8.5% fast for almost 2 years before anyone caught it. Client is a cold storage facility with high usage - about 45,000 kWh monthly. Lesson learned: if usage suddenly jumps without operational changes, demand meter testing immediately. Anyone else seen accuracy issues with the older Landis+Gyr E350 series meters?

Excellent work catching that meter error, John! The E350 series meters you mentioned do have known accuracy drift issues after 10+ years in service. I've seen several cases where temperature cycling in outdoor installations affects the current sensing circuits. For cold storage facilities, I always recommend annual meter testing given the high financial exposure. Did Evergy cover the testing costs, or did you have to push for that? Most utilities will reimburse testing fees when meters fail accuracy standards.
