While the Illinois Commerce Commission’s Order approving the IPA’s Supplemental Photovoltaic Procurement Plan declines to adopt a specific standard that meters must meet, it does require that the IPA’s Plan include references to “revenue-quality” meters, with “revenue-quality” defined as achieving accuracy ranges that the IPA determines are necessary to receive SRECs in the applicable utility’s service territory.

Please refer to the IPA “Revenue-Quality” Metering Accuracy Standard and Acceptable Technologies, which are posted here.
