Indian telecom sector has experienced a phenomenal growth in the recent past and is rising exponentially. The Government is taking initiatives on various fronts for increasing Tele-density and Broadband penetration in urban and rural India.
Telecom initiatives in rural India face problems for quite some time. In most of the rural areas conventional grid power is not available and in some cases the grid is far away. Wherever the grid supply is available the power quality is erratic. The poor power quality is mainly due to supply interruption, sudden change in voltage, under-voltage/ over-voltage, voltage fluctuation etc.
As availability of quality power in the rural areas, is not assured, battery is used as power back-up which keeps un-interrupted power supply for the desired period. Two of the most common alternate power solutions are diesel generator and inverter-battery systems.
TRAI in its recommendation on approach towards green telecommunications has recommended to initiate measures to green the telecommunication sector, all Infrastructure and services in the Telecom Sector should be Energy and performance assessed. The same is being examined. TRAI recommendations are available on their website.
Going green has become a necessity for Telecom operators with energy cost becoming as large as 25% of the OPEX. With increase in the price of diesel and environmental concern about Green House Gas Emissions, the department of telecom is moving fast making provisions for non-conventional energy, solar & wind power in both remote off grid sites as well as grid sites.
DOT undertook pilot projects in USOF Phase I sites through BSNL in order to take care of Environmental issues and arrive at green solutions for Indian Telecom sector with a focus of cost reductions, power saving, Energy efficiency of mobile telecom networks, reducing associated carbon emissions, and utilizing renewable power sources such as solar energy and wind energy. The renewable energy solar/solar-hybrid systems are found to be technically feasible and financially viable for mobile BTS towers. A considerable carbon reduction has been achieved for reduction in DG operating hours.
