What This Article Covers

1.CERC defers stricter grid deviation penalty norms for wind and solar generators by one year to April 2027.

2.The regulator introduces a phased plan with separate, tighter tolerance bands: +/-5% for solar/hybrid (from +/-10%) and +/-10% for wind (from +/-15%).

3.The move aims to manage grid stability as RE share grows, balancing predictability needs with financial viability of projects.

The Big Picture
Prelims · HighMains · Medium

CERC has postponed stricter grid deviation penalty norms for renewable energy generators by one year to April 2027, providing relief to the wind and solar sectors. The order outlines a phased roadmap to tighten deviation charges, aiming to align RE with conventional power norms by 2031, reflecting India's growing RE capacity and its grid stability challenges.
