  • CERC Delays Stricter Grid Rules for Wind and Solar Generators

    Why in the News?

    The Central Electricity Regulatory Commission (CERC) has delayed stricter grid stability rules for wind and solar generators by one year, giving renewable energy companies more time to adapt.

    About the Central Electricity Regulatory Commission (CERC)

    • Central Electricity Regulatory Commission, a key regulator of the power sector in India, is a statutory body functioning with quasi-judicial status under sec – 76 of the Electricity Act 2003.

    Key Decision

    • Stricter deviation norms postponed
    • Earlier implementation: April 2026
    • New implementation: April 2027

    What Are Deviation Norms

    • Power generators must: Declare electricity supply in advance
    • If actual generation differs:
      • Grid stability disturbed
      • Operators impose deviation charges (penalties)

    Why Renewable Energy Gets Relaxation

    • Wind and solar power:
      • Depend on weather
      • Hard to predict output
      • More variability
    • Hence: Relaxed deviation norms

    Deviation Limits 

    Deviation band = Allowed variation between scheduled power and actual generation without penalty.

    Solar & Hybrid Projects

    • Earlier: ±10%
    • Now: ±5%
      • Must generate closer to committed power
    • Example:
      • Scheduled 100 MW
      • Earlier allowed: 90 to 110 MW
      • Now allowed: 95 to 105 MW

    Wind Projects

    • Earlier: ±15%
    • Now: ±10%
    • Example:
      • Scheduled 100 MW
      • Earlier: 85 to 115 MW
      • Now: 90 to 110 MW
