Introduction
Unreliable electrical grid supply is one of the biggest challenges faced by the rapidly growing telecom tower industry in India. Today, on average, 70 percent of the approximately 400,000 mobile towers in India face electrical grid outages in excess of 8 hours a day. Telecom tower operators currently use diesel generators, batteries, and a variety of power management equipment to address the demand-supply gap. The resulting energy costs alone account for 25 percent of the total network operating costs 1, affecting the profitability of the operators.
