π Description
This policy outlines the Indian government’s commitment to integrating biomass as a co-fuel in coal-based thermal power plants (TPPs). It includes provisions on:
- Tariff structure
- Types of acceptable biomass
- Fuel cost pass-through eligibility
- Penalty for non-compliance
The goal is to curb agricultural stubble burning, reduce carbon emissions, and promote a cleaner, more sustainable energy mix in India’s power sector.
π§Ύ Key Policy Updates
πΉ Original Policy (08.10.2021)
- Encourages TPPs to adopt biomass co-firing.
- Provides tariff mechanisms for Energy Charge Rate (ECR) inclusion of biomass.
- Applicable to plants under Section 62 and Section 63 (competitive bidding) of the Electricity Act, 2003.
πΉ Addendum (03.05.2023): Expanded Biomass Types
Newly Eligible Biomass Materials under Para 4:
- Agro-Residues:
Paddy straw, soya husk, cotton stalk, jawar, bajra, maize, jute, mustard, sesame, etc. (if not used as fodder). - Additional Types:
- Bamboo and its by-products (dust, chips, cuttings)
- Horticultural waste (dry leaves, tree prunings)
- Elephant grass, pine needles, sarkanda
πΉ Clarification (14.05.2024): Section 63 PPAs
- In projects with fuel cost pass-through, biomass pellet costs are also eligible for pass-through in ECR, without invoking Change-in-Law clause unless the cost increase exceeds 10% of the Letter of Credit value.
- Especially applies to Case-2, Scenario-4 plants.
π Applicability: Who Must Comply?
β Mandatory Compliance
- CPSUs: Central entities like NTPC, NLC India Ltd
- State Gencos: All state-run thermal plants
- IPPs (Independent Power Producers): Under PPAs (Section 62/63)
- Private Plants Selling to Discoms: Via long-term PPAs
- Captive Coal Plants: Advisory compliance unless made mandatory by state pollution control boards
β οΈ Penalty for Non-Compliance
π« Enforced by MoP, CERC, CEA
| Issue | Penalty/Consequence |
| <5β10% Biomass Usage | 0.25% of Fixed Cost per Day (per unit of shortfall) |
| Grid Dispatch Priority | Reduced merit order status |
| Environmental Clearance | Delay or rejection in EC/NOC approvals |
| ECR Compensation Disallowed | No cost recovery for biomass if not implemented or reported |
β Compliance: How to Prove Co-firing
| Area | Proof Required |
| Fuel Procurement | Invoices, GST slips, vendor details |
| Feeding Record | Boiler logs, hopper feed logs, system integration data |
| Monitoring Reports | Flue gas analysis, ash content logs |
| Monthly Submissions | Reports to MoP, CEA, SLDC |
| Audits | CEA/3rd-party compliance verification |

π§© Conclusion
The Biomass Co-firing Policy is a critical step toward a sustainable, cleaner energy future for India. It mandates coal-based TPPs to transition partially to renewable biomass fuel sources, offering tariff recovery benefits and helping combat environmental pollution.
All thermal power stakeholdersβcentral, state, or privateβmust align with these rules, submit regular compliance data, and ensure transparency in biomass procurement and consumption.
