- Implicit sub-parts
- Technological and global manufacturing drivers (economies of scale in China, improved PV efficiency).
- Policy and financial drivers (competitive bidding, REWA model, plug-and-play parks, low interest rates).
- Financial health and stranded asset risks for coal-based plants.
- Impact on the coal supply chain, logistics (Railways), and banking sector exposure to thermal NPAs.
- Common pitfalls
- Focusing only on technological reasons while ignoring the impact of reverse auctions and aggressive bidding on tariffs.
- Neglecting the 'related industry' aspect, such as the impact on Coal India Limited or the thermal equipment manufacturing sector (BHEL).
- Failing to mention the integration challenges for the grid which actually adds 'hidden' costs despite low generation tariffs.
- Treating the fall in solar prices as purely positive without discussing the stress it puts on existing Power Purchase Agreements (PPAs).
