Piedmont's average customer count declined 10.9% to 1.07 million, including a 13.7% decline in industrial customers and an 11.0% decline in residential customers. Duke Energy Midwest's total gas customer count increased 0.3% to 564,110, although industrial customers declined 12.7% to 1,979. The filing states that Piedmont's throughput changes are substantially offset by margin decoupling, weather-normalization mechanisms and fixed-price contracts with most power-generation customers.
