Are you looking for ways to cut your site’s energy costs? Energy continues to be a major expenditure for operators with traditional base station sites accounting for 80% of network energy and consuming 25% of the power for air conditioning. To help reduce this, Nokia has launched a new battery solution to cut operators’ cost of site power dramatically.
Advanced battery back-up cuts site costs
The Nokia Flexi Power Battery (FPBC) uses innovative Lithium Iron Phosphate (LiFePO4) technology to provide back-up power for sites. The battery can save as much as 30% of site energy consumption by using an efficient weather-proof feature, which comes as default. The battery can cope with rises in ambient temperature of up to 45oC. This compares with conventional lead acid batteries that require cooling between 20-25oC and can consume 30% of the energy used at the site.
With its zero footprint, FPBC also reduces site space requirements. The compact size offers the benefits of reduced material consumption and easy implementation as it can be hand-carried to the site instead of needing to be moved by heavy equipment.
With less space needed for battery backup power, the solution also helps to reduce site acquisition and rental costs. By using an innovative power system such as the Nokia Flexi Power Rectifier (FPRB) and the FPBC, together with the other Nokia Single RAN equipment, operators can create new types of sites in previously non-viable locations. Both FPRB and FPBC have built-in software to enable remote operation and monitoring and further improve energy efficiency. This small site equipment has the added benefit of being less visually intrusive on the surrounding environment as shown in the modernized site example above.
In locations that are off grid or have a poor grid supply, the continuous use of diesel generators not only increases OPEX but also damages the environment with the released CO2. Using the FPRB with its built-in Energy Management Solution, together with the FPBC, operators can reduce generator running hours by up to 80% – utilizing significantly less power and cutting energy costs by up to 50%. This is modernizing that makes good business sense.
