Re: India's Power Sector

Both thermal and hydro have at least three times higher generated/installed capacity than solar. In the case of thermal, fuel costs are built into the price, but for any given type of power plant it can produce X Watts. Let’s say by 2022 there is 100 GW solar installed capacity, but in reality it wi...

Re: India's Power Sector

But if 3 times panel still make unit cost of power cheaper as compared to coal then unit value lies in solar. Comparison should be on value delivered on the investment. So at 15 % efficiency Solar might trump Coal @ 40 % efficiency. Efficiency of power extraction is never the sole criteria. If you ...

Re: India's Power Sector

The attempt to extrapolate roof top solar to grid scale doesn’t work as the requirement for power will increase for a growing economy. For a house or a building, you know how much your power requirement is which is limited by your current capacity of circuit breakers.

Re: India's Power Sector

Except that for the same amount of power (energy/time) you’ve got to install nearly 3 times the panels. Again as pointed out this does not matter. All the costs are already baked in and given in Rs / kwhr. They’re baked in for a given installed power capacity. If your needs for power exceed capacit...

Ultimately is boils down to cost vs value at the consumers outlet inclusive of ALL costs. Energy conversion efficiency is but one factor in the matrix. If solar can provide cheaper power @ 15 % efficiency vs coal @ 40% efficiency then Solar is better. Except that for the same amount of power (energ...

The reason coal is not attractive is because of natural gas and it's economics, and not solar. Thermal is and will remain the largest (>50%) producer of power in India until 2030. An installed capacity of even 200 GW solar by 2020 will generate less than 40 GW actual; whereas natural gas would need ...
