CEA Grid Emission Factor Lookup
Free tool to look up the latest CEA-published all-India and Batchwise-computed regional + state-level grid emission factors for India, with 3–5 year trends, generation mix breakdowns, and an inline Scope 2 calculator.
Data source: CEA CO₂ Baseline Database for the Indian Power Sector V21.0 (November 2025). Updated when CEA publishes new editions.
The latest CEA all-India weighted-average grid emission factor (incl. RES + Captive) is 0.7117 tCO₂/MWh for FY 2024-25 — commonly applied as the location-based Scope 2 factor for entities operating across multiple Indian regions per the GHG Protocol Corporate Standard.
0.7117 tCO₂/MWh
Weighted-average grid emission rate (incl. RES + Captive), FY 2024-25. Excludes imported electricity. Source: CEA CO₂ Baseline Database V21.0 (Nov 2025).

5-year trend (weighted-avg incl. RES + Captive)
Scope 2 calculator
Methodology applied: location-based per GHG Protocol Scope 2 Guidance, using All-India weighted-average grid (incl. RES + Captive) = 0.7117 tCO₂/MWh (FY 2024-25).
About this calculation: illustrative only. Entity-specific Scope 2 reporting should follow the entity's documented methodology, applied consistently year-on-year and disclosed in the BRSR Core methodology footnote.
Methodology + provenance
For Scope 2 calculations under GHG Protocol location-based method, the CEA-published all-India weighted average grid emission rate (incl. RES + Captive) is commonly applied for entities operating across multiple regions. Computed regional or state factors below may be appropriate where the entity has documented its boundary at that level. Refer to GHG Protocol Corporate Standard and the latest applicable SEBI / SAE / SSAE / ISAE guidance.
What "computed by Batchwise" means
COMPUTED by Batchwise from the same plant-level data, mapping each state to its CEA standard regional grid. Per-region factors for 3 years (2022-23 → 2024-25). Regional factors are NOT directly published in V19/V20/V21 — this is a transparent aggregation.
COMPUTED by Batchwise from plant-level Data/DataBase/Database sheets of CEA editions V19, V20, V21 (3-year history 2022-23 → 2024-25). State factor = sum(plant_emissions_t) / (sum(plant_net_gen_gwh) × 1000). Per-state factors are NOT directly published by CEA — this is a transparent aggregation. State names normalised + whitespace stripped.
