Cell tower power solutions: Optimizing generator efficiency for cost savings

The challenge: Reliable power for cell towers in remote locations

Cell towers around the world must ensure continuous connectivity, even in remote or grid-challenged locations. To meet this demand, most Base Transceiver Stations (BTS) rely on generator sets (gensets) for emergency backup or as a primary power source. However, fuel consumption often accounts for up to 60% of the Total Cost of Ownership (TCO) for gensets supporting mobile network towers, with an average fuel consumption of 1500 liters per year. Given these costs, optimizing genset efficiency-especially the performance and reliability of the alternator-is essential for achieving significant cost savings.

Our solution: Reliable, high-efficiency alternators for telecom

At Nidec Power, we design and manufacture high-performance alternators that deliver reliable power in demanding telecom applications. Our alternators are engineered with top-quality materials, providing long-lasting durability and excellent performance in critical areas:

  • Low reactance: Enhances the alternator's ability to handle load distortions, ensuring stable power output.
  • High efficiency & output: Optimizes fuel consumption and reduces the physical footprint of the genset, lowering overall operating costs.
  • Superior startup capability: Minimizes downtime and ensures quicker recovery from interruptions.

With a proven track record of performance in harsh environments, Nidec Power's alternators are built to withstand the challenges of telecom power systems, delivering reliable, long-term service.

Enhanced performance with AREP excitation technology

Nidec Power's AREP (Auxiliary Winding Excitation) System offers a patented solution that significantly improves the performance and reliability of cell tower power systems. AREP-enabled alternators can sustain longer standby periods compared to traditional excitations systems, resulting in:

  • Better reliability: Optimized for the telecom sector, ensuring continuous power even in extended idle periods.
  • Improved performance: Higher efficiency and reduced maintenance needs. 

Variable Speed DC Alternators: The ideal solution for off-grid telecom towers

For off-grid applications, Nidec Power offers a DC 48V variable speed alternator that adapts to the changing needs of a cell tower. This innovative solution can replace a twin-genset setup, adjusting output power based on the activity of the cell tower. Key benefits include:

  • Fuel efficiency: The alternator operates at lower speeds (as low as 900 RPM) when the tower is idle, reducing fuel consumption by up to 36% compared to traditional diesel-only systems.
  • Advanced battery charging: Features enhanced charging capabilities, making it ideal for hybrid cell tower setups that require efficient power and battery management.

    Key features of the variable speed LSAVS alternator:
  • Automatic voltage regulator (R220-VSG): Provides stable DC voltage output at two different speeds, ensuring optimal performance across various operational conditions.
  • Integrated load control module (CCM): Manages battery charging and supports all battery types, including OPzV, SBS EON, EXIDE, A600, and Evolion.
  • Configurable settings for charging rate, charge limits, and grid paralleling ensure versatility and optimal power management.
