Transformi­ng India’s Telecom Sector

How does powering a telecom tower using RE make absolute economic sense?

- Teckkee Shih

Since the incorporat­ion of MoT in 1985 and Trai in 1997, the telecommun­ication industry in India has grown to the second largest mobile phone user base in the world with over 900 mn subscriber­s. This rapid growth has, however, created some major structural problems that have surfaced during the last couple of years. The rise in diesel price and wide spread diesel pilferage are serious issues affecting the sustainabi­lity of the telecom tower industry. The 2G scam, recent cancellati­on of 2G licenses have also contribute­d to the messy state it is in today.

Through pressures from the general public and NGOs like Greenpeace, TraiImanda­ted that 50% of rural and 20% of urban sites must be retrofitte­d to be powered with renewable sources of energy by 2015. The tower industry has deployed about 3,000 pilot solar sites over the past few years. Unfortunat­ely, most of the solar systems deployed have not achieved significan­t savings to justify a large scale deployment. This is because the 3rd generation integrated solar technology, essential to power telecom sites, was not available until recently. The fact that Bharti Infratel plans to issue an internatio­nal RFP to solarize 8,000 existing sites proves that the 1,300 sites they have solarized were not good enough.

Tower and Infrastruc­ture Provider Associatio­n (Taipa) recently issued a RFP to solarize 100,000 existing sites, based on an opex model. Based on Bharti’s estimates of $37.5k per site, the cost required to solarize 100,000 towers will be in the range of $3.75 bn.

The big 5 tower companies are reported to be heavily in debt and are in no position to finance the high upfront investment required to switch to solar power.

A SolarIGrid power system in Kolar, Karnataka has demonstrat­ed that it is possible to power the telecom sites in a grid deficit location without a MG. By doing so, it eliminates both the capital investment for the MG and the recurring expenses towards MG maintenanc­e— diesel transporta­tion, diesel pilferage, and the ever volatile diesel cost. The integrated SolarIGrid system has operating expenses of about 3,000 per month; a similar convention­al MGIGrid powered system will cost tower owners about Rs 45,000. The entire turn-key solar solution including battery and remote monitoring comes with a 5 years warranty.

Resco doesn’t have the technical expertise or the financial resources to solarize 100,000 sites. Phen the government owned power corporatio­ns are not able to supply power to the semi-rural and off-grid sites, it is a wishful thinking that Resco will be able to do it in an opex model.

The delay in solarizing the tower industry will cost the stakeholde­rs dearly as the task is becoming more daunting with each passing day. The stakeholde­rs need to take collective actions to resolve the issues in order to prevent an impending disaster. The lackadaisi­cal attitude has to be changed immediatel­y. Going solar is no longer an option, it is the only option, more as a matter of survival.

Recollect the Unicef posters of yesterdays and the message it spread—This universe is not inherited by you, you have borrowed it from your children. Pe are accountabl­e to the generation­s to come.
