Advanced Metering Infrastructure (AMI)

Manitowoc Public Utilities completed a conversion of all electric meters in the City of Manitowoc to an electric Automated Meter Infrastructure (AMI) system. 

AMI uses state-of-the-art metering and communication technology to permit secure two-way remote communication with utility meters located at businesses and residences in the city. The two way communication is used to collect daily kilowatt-hour meter readings for billing, monitor system voltages, and provide power outage notifications. Overall, AMI provides proactive customer service, improves system reliability, will provide for power outage notification and management, and permits more efficient delivery of utility services.  Long term, AMI can be used for electric distribution system automation, load management, and dynamic energy pricing.

During 2019, MPU crews installed the sixteen data collection points (gateways) on utility poles and made connections to MPU’s existing fiber optic network. Almost all of the 18,000 electric meters in the City were replaced during 2019 with the remainder completed in 2020. MPU has also configured an automatic data transfer from the AMI system to the utility billing system and a new customer portal, where customers have on-line access to energy and billing data. This is particularly useful for commercial and industrial customers to monitor energy use patterns, and take advantage of off-peak energy pricing. Information on the portal can be found by clicking here.

A future feasibility study will be conducted to update all water meters with AMI technology, including requesting approval from the Public Service Commission of Wisconsin. Twenty water meters have currently been installed in 2019 as a pilot test to prove the manufacturer has the capabilities to convert all the water meters to AMI in the future.
