That is absolute nonsense. It excludes intermittency and integration costs. Just from skimming it almost every variable chosen is favorable to renewables and the worst possible case for fossil fuels. The notion that solar is cheaper than coal as a peak power source in a developing nation like india with significantly higher costs of capital is laughable.

Hmmm, I feel like your sources of information are years out of date. Care to elaborate on your sources? First, intermittency and integration costs are a huge straw man because they aren't a problem until you get well over 50% penetration of non-dispatchable generation (e.g. renewables)[1]. For the first 50% of the transition, solar or wind by themselves are way way cheaper[2], and by the time batteries are needed at scale, they will be cheap enough to make dispatchable renewables cost competitive[3]. Second, India is currently building way more solar than coal[4]. Also, they are expecting solar + storage to be cheaper than coal within 8 years[5]. So your assertions about India are way out of date. I'm a bit worried why you still believe the renewable intermittency is a problem or why coal is cheaper. Your "laughable" confidence is likely to lead to you completely missing out on the profits from deploying renewables and storage. Oh well, I guess more money for me then.
