The Rs 5 crore green project is likely to be ready in next two years. "Currently we use electric and diesel-powered boilers. But in winters hydro electricity almost dries up in Kashmir and we face outages. The solar-powered system will help us reduce dependence on conventional power. But a back up will be kept to heat up the liquid to required level for comfortable heating," said an official.
The AAI is also going to store energy by having batteries charged with the solar power and use them at night. The cycle of charging-using-recharging is expected to lead to some insulation from frequent power cuts.
Apart from Leh, AAI is also aiming to generate 250kw at its headquarters (Rajiv Gandhi Bhavan) in Delhi. "We plan to use this energy for our lighting and some power load (except ACs) like running computers. There are two options. We can either use the power or supply it to the grid," said the official. The Delhi project is expected to cost Rs 4-4.5 crore and be ready by next April.
AAI is also working on some other green projects too. There has been plans to use solar energy for airconditioning in the proposed new terminal at Jaisalmer. That plan is still, however, being worked out and expected to be ready in a few months, said sources.
In fact, all new airports are aiming to get a green tag through energy efficient designs. Wherever permitted, like Delhi, the new airports are undertaking rain water harvesting, water recycling along with energy saving techniques. "Being world class does not mean just having a fancy glass-and-steel structure. We have to aim at being sustainable," said a senior AAI official.
