PowerLink TE series energy storage products: Empowering telecom base stations and practicing green and low-carbon practices

Under the dual carbon targets and ESG (Environmental, Social, and Governance) compliance requirements, carbon emission reduction has become a crucial task for operators in the telecommunications industry. Base stations, as major energy consumers, require low-carbon transformation of their power supply systems. Powerlink’s TE series energy storage batteries (power ranging from 3kW to 12kW) are specifically designed for telecom base station scenarios. With their core advantages of precise adaptation, high energy efficiency, and clean, low-carbon operation, they provide an integrated solution for the energy transformation of telecom base stations from four dimensions: low-carbon empowerment, structural optimization, efficiency improvement, and intelligent operation and maintenance, helping the industry achieve green and sustainable development.

Low-carbon empowerment: Solving the emission reduction problem of base stations and activating new momentum for green development

Behind the widespread coverage of telecommunications base stations lies enormous energy consumption and carbon emission pressure—especially for off-grid base stations in remote areas, which have long relied on diesel generators for power. This not only results in high energy costs but also generates significant amounts of carbon dioxide and noise pollution, contradicting the global trend of low-carbon development. Powerlink TE series energy storage batteries, with their synergistic “energy storage + photovoltaic” model, have become the core support for carbon emission reduction in base stations, making each base station a crucial node in low-carbon development.

Leveraging precise charge and discharge control technology and high energy conversion efficiency, the Powerlink TE series can efficiently store photovoltaic clean energy, replacing traditional fossil fuel power generation and reducing carbon emissions at the source. Referring to industry-standard green electricity emission reduction calculations (1 kWh of green electricity achieves approximately 0.000785 tons of CO₂ emission reduction), one TE series 8kW energy storage battery, combined with a photovoltaic system, can consume approximately 7300 kWh of green electricity annually, equivalent to a CO₂ emission reduction of 5.73 tons, equivalent to planting 73 trees (calculated based on 78.5 kg of carbon sequestration per tree per year).

In a “zero-carbon smart base station” project in the Middle East, all 113 communication base stations are equipped with Powerlink TE series energy storage batteries (8-12KW) and photovoltaic modules, completely replacing diesel generators for power supply. Based on local sunlight conditions and base station load calculations, the project has reduced CO₂ emissions by more than 570 tons throughout the year, solving the power supply problem for base stations in desert areas.

Energy structure optimization: increasing the proportion of renewable energy and building a new diversified energy supply system.

Currently, renewable energy sources such as photovoltaics are increasingly used in the power supply of telecommunications base stations. However, due to the influence of sunlight conditions, photovoltaic power generation suffers from intermittency and volatility, resulting in low utilization rates of renewable energy and difficulty in stably supporting 24/7 power supply for base stations. Most base stations still rely on fossil fuels from the power grid for supplementary power, hindering the optimization of the energy structure. Powerlink’s TE series of small energy storage batteries precisely meet the power needs of telecommunications base stations. With their flexible adaptability, they effectively break through the bottleneck of photovoltaic power supply, significantly increase the proportion of renewable energy, and promote the transformation of base station energy supply structure towards cleaner and more diversified approaches.

The Powerlink TE series can flexibly match the capacity of photovoltaic modules according to the differences in the power load of different base stations, realizing a closed-loop mode of “photovoltaic power generation + energy storage + on-demand power supply”.

In a city, a 3.2MW photovoltaic module was installed on the rooftops of 70 base stations, along with Powerlink TE series 6KW energy storage batteries. According to publicly available data, each base station generates more than 3086 kWh of electricity per year, and the 70 base stations generate a total of about 220,000 kWh of green electricity annually. Through an intelligent control system that predicts changes in solar irradiance (with a 4-hour prediction error of <3%), the power supply sequence of “photovoltaics-energy storage-grid” is utomatically switched, increasing the proportion of photovoltaic power supply to base stations to over 60%. This completely changes the traditional energy supply pattern of base stations, which is “grid-based and photovoltaic-supplemented”, and realizes the efficient utilization of renewable energy.

In remote, wilderness areas, for base stations without stable grid coverage, Powerlink TE series (10-12KW) energy storage products work in tandem with photovoltaic modules to build off-grid hybrid energy systems. Combined with optimized off-grid power supply system design, they can maximize the absorption of photovoltaic energy, allowing the proportion of renewable energy to steadily increase to over 90%, truly realizing “green electricity-led” power supply for base stations and promoting the upgrading of the energy structure towards low-carbonization.

Efficiency Improvement: Precisely reduce consumption and losses to achieve efficient energy utilization.

Improving energy efficiency is crucial for achieving both low-carbon development and cost savings. Traditional telecommunications base station power supply models suffer from problems such as wasted excess photovoltaic power, excessive grid transmission losses, and low diesel generator efficiency, resulting in poor energy utilization. Powerlink’s TE series energy storage batteries, with their refined control and low-loss characteristics, reduce energy loss and waste throughout the entire process of storage, conversion, and power supply, achieving a comprehensive improvement in base station energy efficiency.

On the technical level, the Powerlink TE series not only adopts an advanced Battery Management System (BMS) but also innovatively incorporates a high-voltage DC power supply architecture, achieving an iterative upgrade in power supply technology and further unlocking energy-saving potential from the transmission stage. This architecture comprehensively upgrades the DC 48V power input commonly used in traditional telecom base stations to a DC 300V high-voltage input. Based on the circuit transmission loss calculation formula, line loss is proportional to the square of the transmission current. High-voltage input can significantly reduce transmission current, thereby achieving a breakthrough effect of reducing line loss by 70%. This reduces waste from the source of energy transmission, ensuring that every kilowatt-hour of electricity is efficiently delivered to the end user. Meanwhile, with the widespread deployment of 5G base stations, their power consumption is nearly three times higher than that of 4G base stations. Traditional power supply architectures are unable to meet the high power consumption requirements. However, the DC 300V high-voltage DC power supply architecture of the Powerlink TE series can perfectly match the high power consumption scenarios of 5G base stations, providing stable and efficient power supply support. Actual project verification shows that a single station can save over 13,000 kWh of electricity annually. According to the industry’s common green energy emission reduction calculation standard (1 kWh of electricity is equivalent to a reduction of 0.000785 tons of CO₂), this can indirectly reduce carbon emissions on the power generation side by approximately 10.21 tons, achieving a dual benefit of energy saving and carbon reduction. At the operational level, this series of products can respond in real time to changes in base station power load, smoothing out grid load fluctuations and reducing grid transmission losses. Simultaneously, it efficiently stores excess electricity generated during peak photovoltaic power generation periods, avoiding waste of green electricity and achieving a highly efficient “peak storage and valley use” operation mode. In a high-altitude base station project, with an average altitude of 4,250 meters, there are significant differences in photovoltaic power supply between day and night. Some base stations have been upgraded to 5G base stations. After being equipped with Powerlink TE series 12KW energy storage batteries, optimized for the low-temperature environment of the plateau, and equipped with a DC 300V high-voltage DC power supply architecture, the problems of excess photovoltaic power and insufficient power supply at night have been completely solved. It has also been more effectively adapted to the high power consumption requirements of 5G. The energy utilization efficiency of the base station has been significantly improved from the original 65% to 88%, which is in line with the efficiency improvement law of energy storage application in high-altitude base stations. It not only ensures a stable 24-hour power supply for the base station, but also realizes the efficient use of energy, so that every kilowatt-hour of green electricity can play its maximum value.

Intelligent Operation and Maintenance: Data-Driven Precision Carbon Reduction

The EnerWeb platform provides a data-driven management tool for carbon reduction effectiveness. The platform can automatically generate carbon emission reports and provide real-time statistics on key indicators such as photovoltaic carbon reduction, diesel savings, and grid electricity substitution, helping operators intuitively understand carbon reduction results. Simultaneously, it predicts energy demand based on historical data and optimizes dispatch strategies. For example, by analyzing base station power outage patterns, it sets charging and discharging thresholds for energy storage batteries to avoid unnecessary generator starts, further reducing carbon emissions. After adopting the TE series and optimizing through the EnerWeb platform, a European operator reduced the annual generator operating time of its base stations from 200 hours to 50 hours, increasing annual carbon reduction to 35 tons, exceeding its ESG carbon reduction target.
