Finland is a forerunner in large-scale AMR (automated meter reading, known also as smart metering) roll-out worldwide, not only in coverage of installations, but also in functionality and utilization of AMR system in various business processes.In 2009, the Finnish Government passed a new act, which states that at least 80% of the customers of each distribution system operator (DSO) must have AMR implemented by 31 December 2013. In practice, almost all customers are provided by a new AMR meter. The law requires the AMR meter that features hourly energy measurement and registrations of quality of supply-and-demand response functionality.AMR system installation is not only energy remote reading, but it enables real-time two-way communication between customers and other actors and offers huge amount of data for developing new functions for smart grids. The use of AMR data in various functions increases cost effectiveness of AMR investments. AMR system with relating ICT (information and communications technology) systems and business processes forms a larger entity to create added value for customers, DSO, energy retailer, and service providers. AMR is an enabler of competition in electricity market for enhancing flexible change of energy retailer.Hourly measurements enable new kind of dynamic tariffs that support energy-efficient targets and operation of electricity market. Using hourly measurements, more accurate and even customer-specific load models can be created to support load estimation and forecasting.By integrating AMR system with SCADA (supervisory control and data acquisition) system and DMS (distribution management system), network management can be enlarged also to cover low voltage networks, for example, for automatic indication of burnt fuse.AMR system enables also new functions for customer service, for example, as web-based applications for the end customers. Household-level loads now in time-of-use control can also be dynamically controlled by electricity retailers via AMR systems.
