What are Smart Meters?

Smart meters represent a significant upgrade over traditional analog meters. While analog meters only measure total energy consumption, smart meters provide detailed, time-stamped data on energy usage. This granularity allows for a better understanding of when and how energy is being used, enabling both consumers and utilities to make more informed decisions. Smart meters also support two-way communication, meaning they can send data to the utility and receive information back, such as pricing signals or demand response requests.

The key features of smart meters include:

• Real-time data: Smart meters record energy consumption at frequent intervals, often every 15 minutes or less.
• Two-way communication: They can transmit data to the utility and receive information back.
• Remote monitoring: Utilities can monitor meter status, detect outages, and perform remote connects and disconnects.
• Advanced metering infrastructure (AMI): Smart meters are a key component of AMI, which includes communication networks, data management systems, and software applications.

Importance of Technology Codes

Technology codes and standards are vital for ensuring the reliable, secure, and interoperable operation of smart meters. These codes define the technical specifications, communication protocols, and security requirements that smart meters must adhere to.
