According to Hubballi Airport Director Pramod Kumar Thakre, by March 2021, the city's airport is
expected to generate 140 lakh units of electricity through its eight-megawatt ground-mounted
grid-connected photovoltaic(PV) solar plant that is being installed here.
The power thus
generated by photovoltaic solar panels will be fed to the high-tension grid of Karnataka Power
Transmission Corporation Limited on drive wheel system and take credit in the electricity bill of
all airports in Karnataka managed by AAI. Once completely implemented, the airport’s
dependence on external power supply will be reduced by at least 85% annually.
As of now, the total power consumption of airports in Karnataka (Belagavi, Kalaburagi, Mysuru,
and HAL Airport in Bengaluru) is around 132 lakh units per year, whereas the Hubballi Airport
will be generating 140 lakh units.
Madhav Infra Private Limited, a Gujarat-based company has been executing the project at an
estimated cost of Rs 64 crore. Works such as laying cables, setting up transformers, and other
civil works have been completed, while the remaining work is expected to completed by Marchend or early April, said Thakre.
The entire project is being implemented on the 38 acres of the airport land. More than 22,500
solar panels will be installed on 24 acres of land in such a way that the PV solar system gets
the maximum amount of solar radiation available each day throughout the year based on
orientation and tilting of modules, thus avoiding shading, he said and added that in order to
achieve a higher system voltage, modules are installed in a row arrangement, called a string.
A
higher system voltage has the advantage of lesser installation work, higher efficiency of the
entire plant and usage of smaller cross section cables.
