The market for energy storage (ES) and distributed generation (DG) solutions for telecom infrastructure sites is growing, particularly in developing markets—especially Africa and parts of Asia Pacific—where the number of off-grid (or bad grid) mobile tower sites is growing markedly.

This is the key conclusion of a new report from Navigant Research, which anticipates global telecommunications network provider spending on DG and ES purchases will grow from $2.4 billion in 2015 to $3.4 billion in 2024.

Wireless providers—and subscribers— have little tolerance for power outages that interrupt service and most mobile tower sites have battery-based backup systems, but increasingly, new technologies such as lithium ion (Li-ion)-based systems are being installed.

Furthermore, DG is one key tool that network providers can now use to reduce their energy costs, the report states, by avoiding high retail electricity rates.
