During the rollout of our Automated Metering Infrastructure (AMI), NIPSCO discovered an issue with a very limited number of NIPSCO’s existing gas meters, impacting less than 1% of natural gas customers. While this historical issue was discovered during AMI rollout, it is not related to or caused by this new technology in any way. As part of the AMI project, NIPSCO identified that a limited number of gas customers were being billed for more or less than actual usage prior to the AMI installation. Customers do not need to take any action at this time. We are committed to accuracy in our metering and billing processes and have already taken steps to verify and correct any impacted bills. Those customers who are identified as being impacted by the billing discrepancies are being notified by NIPSCO through direct mail and email. NIPSCO will also be issuing 12-month refunds to those who have been overbilled. We appreciate your patience and understanding as we work to resolve this matter.
