Smart metering and circular economy

Smart metering and the circular economy: why it is a strategic issue

When we talk about sustainable smart metering, we must consider the entire life cycle of smart meters: from design to operational management, right through to end-of-life. Utilities manage millions of devices across the country, with significant impacts in terms of:

• raw material consumption;
• electronic waste generation;
• maintenance and replacement costs;
• emissions linked to logistics and field operations.

In this context, applying the principles of the circular economy to smart metering means transforming meters from simple measuring instruments into digital assets managed throughout their entire lifecycle.

The first step towards circular smart metering concerns the design of the devices. An increasing number of manufacturers are adopting approaches such as:

• design for disassembly, to facilitate the recovery of components;
• the use of recyclable or low-impact materials;
• modular architectures, which allow for the selective replacement of parts;
• the reduction of critical components and rare earth elements.

From a technical perspective, this approach makes it possible to reduce the lifecycle cost of meters and improve the overall sustainability of the system.

Asset Management and Meter Data Management: the heart of the circular economy

The real leap forward occurs at the operational stage. Thanks to Meter Data Management (MDM) systems and smart metering software platforms, utilities can transform measurement data into a tool for circular asset management. In particular, the data enables real-time monitoring of meter status, identification of anomalies and performance degradation, avoidance of premature replacements, planning of targeted interventions, and extension of device lifespans. This approach enables predictive maintenance, reducing operational costs and environmental impacts.

One of the most significant features of modern smart metering is the ability to update devices remotely via Firmware Over-The-Air (FOTA). From a technical and environmental perspective, this allows for the updating of functionality without replacing hardware, improves device security, enables compliance with new regulations and standards, and extends the life cycle of meters. The direct consequence is a significant reduction in electronic waste and in the costs associated with the mass replacement of assets.

The contribution of Terranova’s smart metering solutions

In this context, software platforms play a vital role. The smart metering solutions developed by Terranova are fully aligned with this circular approach, enabling advanced and sustainable asset management. In particular, the Meter Data Management platform allows for:

• the integration of data from multi-vendor and multi-service meters (electricity, gas, water);
• ensure data quality, validation and archiving;
• monitor device performance throughout the entire lifecycle;
• support advanced analytics for predictive maintenance and optimisation.

These capabilities enable utilities to transition from reactive to data-driven asset management, reducing unnecessary replacements and improving operational efficiency.

Furthermore, the ability to centralise and analyse large volumes of data is a key factor in enabling strategies for sustainability, waste reduction and resource optimisation, in line with the principles of the circular economy.

The adoption of a circular model in smart metering delivers tangible benefits:

• reduction in electronic waste;
• lower use of raw materials;
• optimisation of operating costs (OPEX);
• longer asset lifespan;
• improved ESG indicators;
• increased return on investment (ROI).

This makes smart metering not only an enabling technology, but a strategic lever for sustainability.

The integration of smart metering and the circular economy represents one of the most significant developments in the utilities sector. Thanks to digitalisation and the intelligent use of data, it is possible to manage meters throughout their entire lifecycle, reducing waste, costs and environmental impact.

Utilities that adopt this approach will be better placed to tackle the challenges of the energy transition, transforming asset management into a sustainable competitive advantage.
