Electricity metering systems measure energy consumption, monitor its quality and communicate this information from meter to concentrator or cloud so that utilities can better manage the use of energy by means of load management. Real-time reporting of energy measurement improves consumer awareness leading to waste reduction thus lower expenses. The data obtained through the use of smart meters enables utilities and energy distributors to optimize power distribution losses across the grid. The result is lower cost, higher reliability, reduced tampering and carbon emissions.

ST has a comprehensive range of multi-protocol programmable power-line modem communication solutions that comply with standards including G3-PLC, Prime, Meters and More and are already used in more than 100 million smart electricity meters worldwide.

In addition, we can help designers using our unique system-level application know-how and a wide range of semiconductor products including energy metering ICs, long- and short-range wireless connectivity solutions, 8- and 32-bit microcontrollers as well as high-efficiency power supply and management devices, sensors, EEPROMs, secure elements and protection devices.
