Soil & Land Strata: The land strata of the project site varied extensively. And the land is an undulated rocky terrain. So, the project team faced immense difficultly in moving the construction equipment and machineries. Removal and shifting of huge quantity of boulders/ rocks from the excavated trenches after blasting was required.
Mitigation: A planned & quick action plan was derived and the boulders were successfully removed. Temporary murram road was built to access the site for construction and moving of machineries.
Weather: Extreme weather conditions at the project site posed a challenge. The summer temperature was as high as 50°C from April to July.
Mitigation: Controlled working hours, project management schedule with utmost precision along with a dynamic work schedule allowed us to deliver the project on time. Arrangement for continuous hydration of the workers ensured better productivity.
Local Manpower: The project’s major problem lied with local unskilled manpower.
Mitigation: To quickly address this issue, we had to engage and train local workers for temporary works and hire tractors, trolleys and other small machineries locally to aid the process.
Engineering Issues: There was presence of sheet rock which required multiple blasting cycles to achieve the desired depth of cable trench. Also non-availability of natural earth material for back filling presented engineering challenges.
Mitigation: Multiple and yet careful execution of blasting was done to reach the desired trench depth for cable placement. And natural earth material was sourced from other places on time to avoid any delay in the project.
Construction Power: There was an absence of a continuous power source. But arranging for it on a quick basis was quite difficult considering the remoteness of the area.
Mitigation: We procured power from nearby for construction site and used Diesel Generator sets to get uninterrupted power. For civil works, we had to arrange meeting with local administration for arranging for canal water from nearby areas.
Total 8,48,680 solar PV modules (approx.) were installed in the 200 MW plant.
Total 10000 MT of steel were used for the mounting of the module structure.
Power is evacuated at 33 KV level in 2 pooling substations of 33/220 KV capacity, which further gets evacuated to 220/400 kV main substation.
Expected Annual Energy Yield 446 million unit. The plant is also expected to reduce CO2 emissions to the tune of 2,46,000 metric tonnes annually.
