Their rollout is expanding as utility providers and governments invest in modernizing infrastructure to improve efficiency. Smart meter power line communication (PLC) modems support this trend by integrating with smart home systems, allowing homeowners to automate energy monitoring, manage consumption, and synchronize with broader home automation platforms. For instance, in August 2025, the UK government reported that large energy suppliers in Great Britain installed 740,000 smart and advanced meters in the second quarter of 2025, a 3.3% increase compared to the same period in 2024, with installations 6.6% higher than the second quarter of 2024. Consequently, the increasing rollout of smart meters is driving growth in the smart meter power line communication (PLC) modem market.

The growing adoption of digital transformation is also expected to propel growth in the smart meter power line communication (PLC) modem market. Digital transformation involves integrating digital technologies across all business operations to improve efficiency, enhance value delivery, and enable innovation while promoting agile, data-driven practices. Its adoption is rising as organizations seek to provide faster, more personalized, and seamless customer experiences to remain competitive. Smart meter PLC modems support digital transformation by enabling secure and reliable data exchange over existing power infrastructure. They enhance utility operations and customer engagement through real-time monitoring, advanced metering, and data-driven decision-making within smart grid ecosystems. For instance, in July 2024, the Office for National Statistics, a UK-based government agency, reported that the digital infrastructure program received $535 million (£434 million) in investment by 2022, with an additional $907 million (£736 million) allocated for 2023-2025. Therefore, the rise in digital transformation is driving the growth of the smart meter power line communication (PLC) modem market.

Major companies in the smart meter power line communication (PLC) modem market are focusing on technological innovations, such as programmable multi-protocol PLC modems, to enhance data flexibility, improve interoperability, and secure energy information exchange across modern utility networks.
