Energy emerges as telecom's next competitive advantage

By Basant El-Faramawy

The rapid expansion of 5G, edge computing and AI-enabled services is driving a surge in power consumption across telecom networks, turning energy from a predictable operating expense into a strategic business consideration. Operators now face volatile electricity prices, growing sustainability expectations and pressure to improve profitability, prompting a fundamental rethink of how network infrastructure is designed and managed.

The industry's most underutilised energy asset

Every telecom site relies on backup batteries to maintain service during outages, yet in regions with reliable grids such as Europe these systems spend nearly their entire lifespan fully charged and idle. This represents a significant untapped resource. As electricity markets become more dynamic, backup batteries can shift from passive emergency infrastructure to active participants in daily energy management, reducing operating costs while preserving network resilience.

Why traditional energy management no longer works

The economics of electricity have changed dramatically with dynamic tariffs, peak-demand charges and rising renewable generation. The timing of consumption is now almost as important as the volume. Advances in lithium-ion battery technology and intelligent energy management software allow operators to charge batteries during low-price periods and discharge during peak tariffs, cutting peak demand and lowering energy bills without compromising backup capacity.

Turning backup power into business value

A leading European operator managing approximately 700 sites recently piloted this approach across 171 locations using cyclic lithium-ion batteries integrated with Delta Electronics' ORION intelligent power controller. The system continuously analyses electricity tariffs, battery health, site load and required reserve capacity to determine optimal charging and discharging schedules. The pilot achieved energy cost reductions of 12–15 per cent per site, effectively offsetting the lithium-ion investment over the battery lifetime. Real-time monitoring also enabled predictive maintenance and reduced unnecessary site visits.

Beyond cost savings: building smarter telecom networks

Intelligent energy management extends beyond electricity bills. As networks become increasingly software-defined and data-driven, energy infrastructure is following the same path. Automated decision-making, predictive analytics and real-time monitoring allow operators to optimise performance across thousands of distributed sites, improving operational efficiency, strengthening resilience and supporting sustainability goals.

From telecom sites to distributed energy assets

Europe hosts more than 720,000 telecom towers, each with energy infrastructure that could contribute to a more flexible electricity system. As renewable generation expands, these distributed resources will become increasingly valuable for balancing supply and demand. Sites originally designed solely for backup power could evolve into intelligent energy assets that optimise consumption, reduce demand peaks and potentially participate in future flexibility markets while protecting critical communications infrastructure.

The next evolution of telecom infrastructure

For decades, operators have invested in faster, more reliable networks. The next opportunity lies in unlocking greater value from existing infrastructure. Battery systems can become strategic energy assets that enhance resilience, improve efficiency and prepare operators for the next generation of digital infrastructure. As AI, edge computing and digital services increase electricity demand, competitive advantage will depend increasingly on how intelligently operators manage the energy that powers their networks.
