Bharti Airtel’s Nigeria unit has contracted Ericsson to upgrade an initial batch of 250 diesel powered base stations with new ‘green’ sites from Sweden’s Flexenclosure.
The solution, based on Flexenclosure’s E-Site, will allow Airtel to harness solar and wind energy at the sites to minimise diesel consumption – and yes, CO2 emissions.
According to Flexenclosure, Airtel has been testing its solution in Kenya for the last two years and has achieved demonstrable results, including a substantial reduction in diesel consumption compared to previously 100% diesel powered sites.
In addition to optimised solar and wind generation systems and a bank of batteries to storage energy, E-Site solution also includes sophisticated control system that ensures maximum power is captured from the renewable energy sources and that the use of the battery bank is highly efficient, the company said.
Under the agreement, Ericsson will be responsible for implementation and maintenance services for all the sites.
