Our glorious sun has always been radiating enormous energy but never before has not been harnessed to its full capacity. This free energy requires small investment over a long life span to make it usable and its use is actively being promoted by government looking to the rapidly increasing demand and depleting fossil fuels which cause environmental pollution while electricity is generated. So shifting to renewable sources such as solar ,wind etc was the need of the time.
So here we have the world’s largest solar plant in Kamuthi,Tamil Nadu. Covering 2500 acres of land with 2.5 Millions of solar modules was a tough and challenging task to be achieved in a short duration. It was all possible with the hands of 8500 workers who worked 260 days and night.
Land acquisition- Having the worlds largest solar plant required a vast land area. @500 acres of land had to be acquired to get it started.
Resources Arranging manpower and equipment in the remote village was a difficult task and all to be present on time as and when available.
Storage- All in all 6000 containers of materials were brought through sea from all over the world and vast warehouse of 120000 sq m was to be built to store these safely.
30 days past the start of the project materials arrived but the site wasn’t ready to store them and the project was running late by a month.
200 days left until finish and leveling of the surface had begun, survey was being conducted and laying of 1200-1500 piles per day out of a total 4,00,000 piles and had to be contracted to fasten the progress.
Suppliers- Validation of multiple suppliers to fulfill the demand of 30000 meteric tons of steel and 7700 km in length of galvanized steel wires was a tedious task. The wires so heavy that 50 persons were needed to pull at a single point of time.
Weather- the 2015 northeast monsoon had a devastating impact on the project and the daily working efficiency reduced greatly which delayed the project.
90 days were to go and continuous on site testing was performed using SCADA
60 days in hand and intallation of mechanised cleaning equipments began to clean panels without water using robotic system remotely monitored.
34 days and operations and mantainance team were on the field when the transformer brokedown.
Time was slipping out of hand it was 20 days to deadline with still 180 MW of modules left to be installed.
Another challenge was on its way that was to be taken care of.
Partial solar eclipse – in such case the sudden variation of energy leads to fluctuating production and precautions need to be taken to prevent damage to the solar grid.
The last 15 days for the task. 120 MW of modules were installed.Connections made and checks completed.
Finally the day to be marked in the History of the Adani group had arrived project succesfully finished on March 31st 2016.
