Hindustan Times reports that in a government initiative – a R 120-crore project under the Jawaharlal Nehru National Solar Mission (JNNSM) of the Ministry of New and Renewable Energy (MNRE), will kick off in Andhra Pradesh, Bihar and Uttar Pradesh and involve state-owned Bharat Sanchar Nigam Ltd and tower infrastructure firm GTL and Indus Towers. Under the project the existing towers will be transformed into solar powered towers.
Of the 400 towers, installed at R30 lakh each, 100 will be of BSNL. The ministry will subsidise about 30 % of the tower costs. Usually these towers require large amounts of electricity and are connected to the National Grid
“But, in the uneven areas where the grid connectivity is erratic, ministry has planned to construct Solar Photovoltaic (SPV) plants to generate DC electricity, which in turn will be stored in the battery to get consume for transmitting signals” Said, minister for new and renewable energy Farooq Abdullah.
The ministry claims that in an estimate the country will save up to 260 crore liters of Diesel annually
Multiplied by 40 = 1,040 Crore Rupees saved annually (approximate)
A little more research by iGyaan.in led to Delta Hybrid Renewable Energy Solutions (RenE), which were announced recently on 31st Jan 2011. Delta announced that their RenE solutions feature a modular power supply concept that can use any combination of solar power, wind turbines, mains power, diesel generators and fuel cells, which may reduce payback time as well as electricity bills for over 50%.
“With RenE, telecom customers can go all green using only renewable energy sources whether it’s in the heart of the city or in the remotest areas of the globe. Compared with utilizing the more expensive traditional energy sources, using renewable energy sources alone or in a hybrid solution may bring down payback time from 7 to 2 years, varying with site designs,” says Krzysztof Puczko, Product Manager, RenE-Hybrid Power Systems.
Delta Hybrid solution includes Solar panels, generator, AC/DC power system, and battery. The product is made out of state of the art facility at Rudrapur which has green building credential too. Best Suitable for Rural or Remote Sites as it offers complete integrated power system which is Simple to install and easy to maintain with added advantage of Remote Control and Monitoring including Data Logging. All in all, RenE is an energy-efficient and OPEX-optimized solution for ensuring lower CO2 emissions.
Here is to a greener India, cheaper communication and hopefully, better performance.
dear sir, i have a space for mobile network towerlocation.dear sir, i have a space for mobile network towerlocation.there is no any UNINOR mobile tower. please visit the location...at-ijapura(barot),post-palej,ta&dist-mehsana,pin-384410 my contact number-9723865234 do reply .........mitesh patel.
Furthermore, the costing is vague. Of the cost of Rs 30 lakhs, what's the solar panel and mounting and labor cost? And how do they arrive at the estimate of 260 crore liters of diesel saved? Does this mean that 400 towers use 260 crores of diesel ie 65,00,000 liters each annually? Impossible. Like any other govt. project -- not fully thought through and probably meant to help milk the taxpayer with promises that will never last for longer than a year. We'll probably find the solar panels being sold in the market a year after their installation or being used in the home of the local tehsildar. Sorry for being cynical but this is a prime example of a great idea poorly designed and impractically implemented. Who'll tell Mr F. Abdullah this?
A wonderful idea but I don't understand why the solar panels haven't been mounted directly onto the tower framework. The capital cost of the solar panel installation has to be kept in mind if the idea is to be propagated even to the private telecom operators. Direct mounting onto the tower framework, 10' from the ground, would eliminate the cost of the separate framework used for the panels as shown in the illustration and also prevent theft. This would make the idea much more sustainable.
good news. nagpal your rock and keep moving ahead it's nice to see heard work youngster like you , I wish you every success and progress and a bright future
