Vodafone Qatar and Alcatel-Lucent announced the deployment of the first hybrid powered Base Station in Qatar, using an integration of solar and wind energy. Vodafone and other companies intend to learn from these trial sites and plans to apply these techniques all over the world.
The wind turbine at the Qatar site has been mounted at the top of the existing mast to leverage higher winds. The energy controller brings intelligent control to simultaneously draw power from both the photovoltaic panels and wind turbine, based on solar intensity and wind speed, making the most – at every second – of the two sources’ fluctuating availability. The system also carefully monitors battery charging cycles and diesel generator maintenance runs so as to maximize their lifespan. A full monitoring system enables real-time tracking of all weather and energy parameters; a key component to enabling large scale deployments.

Mobile base station electricity costs could rise by nearly 55% over the next five years unless operators address network inefficiencies and reduce reliance on non-renewable energy resources, according to a new report from Juniper Research. Its author, Dr Windsor Holden, said: “Operators in Africa and Asia who continue to rely on diesel for off-grid generators will find margins increasingly squeezed as their networks expand and diesel prices rise. We believe that unless a transition to generators powered by renewable energy is effected, then many such networks may no longer be financially viable within a few years.”
Other findings from the green base stations research include:
- Base stations are responsible for more than 70% of CO2 emissions in the mobile use phase
- Operators should increasingly seek to utilise feederless sites and distributed site architecture as means of reducing inefficiency
- Adopting measures suggested under the transformational model will enable operators to reduce base station CO2 emissions by up to 30%

State of Telecom in Pakistan has a good post about telecom’s role in conserving energy and saving money.
Last year we saw Telenor and Warid vie in the media as the first one to install solar base stations. That was a start and the trend for green, renewable and more efficient solutions will continue. There is a lot more work to be done in the energy conservation and alternative reneable sources of energy for the technology and telecom industry. The infrastructure elements such as base stations consume significant energy and the data centers needed to run the IT operations are also major energy spenders. The infrastructure sharing idea promoted in Pakistan was also a good point in theory but its actual success has not been reported yet.
Typically, around half of the operating expenditure of a network company is spent on electricity, according to Ericsson. The proportion tends to be higher for operators in the developing world because their base-stations may be in remote areas, and therefore require diesel-fuelled generators. So the recent spike in energy prices has prompted operators to look for ways to cut costs.
The Economist ran a story about green telecom networks and ways to conserve energy in the telecom world. Good tips for saving energy from Economist.com include:
There are some relatively simple ways to reduce the energy consumption of a base-station. The first is to turn down the air-conditioning. Many mobile operators now run base-stations at a standard temperature of 35ºC, rather than the previous norm of 25-30ºC. Studies show that the higher temperature does not reduce the equipment’s reliability or life expectancy. “The biggest restriction is actually our technicians, who do not like going into the hut to work at 35 degrees,” says Andy MacLeod, Vodafone’s global networks director.
Operating at this temperature means ambient air can be used for cooling, even in hot countries. An air-filter is installed on one side of the cabin, and a fan is installed on the other, resulting in a steady flow of air. Vodafone plans to replace air-conditioning with this simpler approach, called “freecooling”, in the majority of its base-stations over the next three years, as part of a plan to reduce its carbon footprint by 50% between 2006 and 2020.
