In any connected home, broadband equipment is like a silent roommate: it’s dependable, always there for you, and only noticed when it throws a tantrum. Typically hidden away in the corner of a home or office space, customer premises equipment (CPE) such as routers and gateways deliver around-the-clock operations to keep everything online – but for many end users, this “always-on” reliability often results in an “often overlooked” energy bill.

Continuous energy consumption is a key issue, with CPE currently accounting for approximately 70% of the energy consumed by fixed-broadband networks within Europe, according to Kearney. This issue is compounded by the growing sophistication of the connected home and the stringent sustainability targets laid out by policymakers and governments across the continent. Since April 2023, the Commission Regulation (EU) 2023/826 has been laying down stricter eco-design requirements for standby and network-standby power consumption for electronic products – including CPE – while industry-led initiatives such as the Voluntary Agreement on Complex Set-Top Boxes has set ambitious targets for minimizing power usage. Finding ways to reduce broadband energy consumption, therefore, is essential.

Small sleep cycles, large-scale savings

One key method of delivering energy savings is through an automatic sleep or low-power mode for always-on equipment.

Allowing a broadband service provider to remotely control the end user’s CPE, backed by intelligent insight and data from the network, will ensure that energy usage can be managed and monitored centrally, resulting in savings across the entire footprint and a strong baseline for efficiency across millions of devices. New power management standardization efforts are enhancing these savings further, resulting in enough energy to, in theory, power up 70 new small data centers across Europe.

The importance of standardization

These efforts equate to 1.3-terawatt hour (TWh) of energy annually across European homes. To put it differently, we are no longer saying these savings are equivalent to provincial towns, but equivalent to the entire annual residential electricity consumption of major cities like Athens, Copenhagen, or Lisbon.

Savings come from enabling everyday CPE to enter low-power or deep-standby modes instead of running constantly at full consumption. Across the roughly 200 million EU households now connected, even small reductions per device quickly scale into an enormous, continent-wide impact.

Ultimately, the reason this works at scale is standardization. Industry bodies such as the Broadband Forum are empowering operators and manufacturers across the globe to implement consistent, automated power saving features without the need for bespoke integrations. By establishing a shared framework, greener broadband equipment isn’t just technically possible, but also deployable, measurable, and impactful across the entire ecosystem.

A united framework for optimal power management

One way of achieving this has arrived through the Broadband Forum’s Power Management initiative, and the extension of the TR-181 Device Data Model, which defines how devices describe their capabilities, report status and controllable parameters to operators. It introduces standardized mechanisms for controlling and monitoring power consumption across key hardware components – including Wi-Fi, Ethernet, USB, and the central processing unit (CPU).

TR-181 represents a clear opportunity for application developers. By exposing power management APIs in the firmware, developers can also create applications that extend the CPE’s capabilities without needing to embed the software on the device. This allows broadband service providers to roll out new energy saving features to already deployed CPE quickly and at scale.

Enabling smarter, low power operations

The latest TR-181 update also brings a wave of new power-management intelligence to broadband devices, giving operators real control over how hardware behaves when inactive.

By enabling fine-grained control of the power states within CPE, the power management initiative provides the means to reduce the energy consumption of devices, all while maintaining maximum performance and service continuity. For instance, a controller can be empowered to turn off specific unused components like USB port power at suitable times, including nighttime.

Hosting a power management solution in such a containerized environment also allows for the movement of power control away from any proprietary, vendor-specific implementations. Open-source frameworks such as prpl are accelerating this transition, providing a vendor-neutral foundation for deploying containerized applications across heterogeneous CPE fleets. As a result, a broadband service provider can easily manage energy profiles across routers manufactured by different companies.

Delivered through new APIs, these changes have introduced physical power-management hooks across embedded technologies, enabled devices to report both total and per-component energy consumption and even added a new “deep standby” mode for power savings as network activity decreases.

Setting the standard for efficiency

These enhancements go beyond simple on/off switches. Devices that implement the new version of the standard can now dim LEDs, scale CPU frequency, power down Ethernet ports using energy detect power down (EDPD), and even dynamically adjust how many Wi-Fi antenna chains are active, all in response to real-time conditions. It’s a smarter, more adaptive way for gateways, extenders, and set-top boxes to stay efficient without compromising performance.

Once these capabilities run over a user services platform (USP/TR-369)-enabled network, they become even more powerful, providing operators with a unified, real-time control plane for managing energy use across Wi-Fi, Ethernet, USB, xPON, Thread, and other network technologies.

Shaping the future of broadband, together

Through these new power management mechanisms, CPE finally gets a well-earned rest. Saving 1.3 TWh every year across an entire continent is what happens when millions of routers, gateways, and set-top boxes are empowered to downshift from being always on, despite limited use.

Operators can now turn wasted watts into continent-scale efficiency gains and by multiplying this small improvement by 200 million households, power entire cities and data centers with the accrued savings. This work signals a coordinated industry move toward broadband that’s both high-performance and low-impact.

By implementing standardized power controls, the entire industry gains a common language for energy efficiency, and an interoperable framework that lets broadband service providers cut consumption at scale while keeping customers perfectly connected.
