According to CRISIL Ratings, power projects worth 46,000 mw are facing viability issues due to lack of long-term buyers for electricity, inadequate fuel supply, and aggressive bidding to win projects and coal blocks.

“Of this, 36,000 mw are coal-based projects within which tariff under-recovery has impacted 20,000 mw of capacities, while the rest are reeling because of inadequate feedstock and poor electricity offtake by discoms. And 10,000 mw of gas-based projects have become unviable because of dwindling fuel supplies from the Krishna-Godavari basin,” the rating agency said in its July 2015 report.

CRISIL believes that merchant power prices will remain subdued over the near-to-medium term on account of large untied capacities leading to increased competition in the merchant market.
