For an increasing number of utility companies, Metering as a Service (MaaS) has become the preferred model to operate the Advanced Metering Infrastructure. Instead of building the technical expertise and resources to manage the advanced metering infrastructure in-house, all daily operations are contracted to an external expert. This relieves resources and allows to focus on utilizing the data to improve end-customer Services as well as grid maintenance and development. MaaS opens signifcant potential to optimize outcome and save costs, like maintaining dedicated expert skills and keeping IT infrastructure up to date and secure.
