Abstract: Prior to 1984, Michigan natural gas utilities were required to adhere to a meter-testing rule that primarily established a quantitative process for removing meters on the assumption that it improved the quality of the overall meter population. The old rule specified that the percentage of meters to be tested in a given year and maximum on-premise meter life was to be based on the percentage of meters tested the previous year that fell within an acceptable accuracy range. The old rule merely determined the workload for a utility. It was not aimed at systematically correcting the deficiencies identified through meter tests. Consequently, it provided no incentive for a utility to improve the level of meter accuracy by identifying and removing poorperforming meters. ReaUzing that the old rule had become detrimental to customers need for accurate metering, Michigan Consolidated Gas Company (MichCon), the Michigan Utilities Association, and the Michigan Public Service Commission developed a new rule that rewards a qualitative process of identifying and removing poor-performing meters. Under the new rule, a utility is required to divide its total meter population in a service into meter classes and to grade each meter by a test point system, which quantifies the extent by which meters tested fall outside the acceptable accuracy range.
