NTPC Limited

NTPC Limited is actively pursuing net-zero goals, aiming to make its townships and offices net-zero in Scope 2 emissions by FY 2025-26 and has a broader roadmap for net-zero GHG emissions. The greenhouse gas (GHG) emissions data for FY 2023-24 and FY 2022-23 are summarized as follows:

  • Total Scope 1 Emissions: Increased from 335.72 million metric tonnes CO₂e in FY 2022-23 to 352.47 million metric tonnes CO₂e in FY 2023-24.
  • Total Scope 2 Emissions: Remained constant at 0.07 million metric tonnes CO₂e in both financial years.
  • GHG Emissions Intensity per Rupee of Turnover: Slightly improved, reducing from 0.000194654 tonnes/Rs in FY 2022-23 to 0.000188722 tonnes/Rs in FY 2023-24.
  • GHG Emissions Intensity (Adjusted for PPP in USD): Decreased from 0.000709791 tonnes/USD in FY 2022-23 to 0.000688157 tonnes/USD in FY 2023-24.

  1. Energy & Efficiency Management

Power Generation and Infrastructure

  • Total installed capacity: 64 GW, with 3.26 GW added in FY 2023-24.
  • Generation: Achieved an all-time high of 2 BU (5.75% YoY growth).
  • Expansion into renewable energy, nuclear power, green hydrogen, and waste-to-energy projects.

Renewable Energy Transition

  • NTPC aims to commission 60 GW of renewable energy (RE) capacity by 2032.
  • 5 GW of RE capacity commissioned in FY 2023-24, including 3.3 GW solar, 213 MW wind, and 32 MW small hydro.
  • NTPC is developing Ultra Mega Renewable Energy Power Parks (UMREPPs) in Gujarat, Madhya Pradesh, and DVC.
  • Focus on energy storage: 4 GW/24 GWh capacity planned, including BESS and Pumped Storage Hydro systems.

Fuel and Resource Security

  • Coal sourcing: Long-term agreements with CIL (214.45 MMT) and SCCL (27.99 MMT); 2 MMT produced from captive mines.
  • Gas sourcing: Agreements with GAIL; procuring RLNG and Spot LNG.
  • Biomass co-firing: Pioneered in India, awarded contracts for 28 million MT biomass pellets.

Nuclear Energy

  • NTPC-NPCIL JV (ASHVINI) developing Mahi Banswara (4×700 MW) nuclear plant.
  • Exploring small modular reactors (SMRs) and uranium sourcing with UCIL.

Green Hydrogen & Chemicals

  • First Green Hydrogen Blending project in Kawas, Gujarat.
  • Hydrogen mobility projects: Fuel Cell Electric Vehicles (FCEVs) in Leh and Delhi NCR.
  • Developing Green Hydrogen hub in Andhra Pradesh for methanol and ammonia production.

Waste-to-Energy and Ash Management

  • 600 TPD Waste to Charcoal Plant commissioned in Varanasi, preventing 7 lakh MT CO2 emissions annually.
  • Contracts awarded for WtE plants in Bhopal, Hubballi Dharwad, Noida, and Gorakhpur.
  • 92% fly ash utilization, supplying to cement, road construction, and mine reclamation.
  • FGD gypsum sales started, reducing reliance on imported gypsum.
  1. Air Quality and GHG Emissions
  • Equipped with Continuous Emission Monitoring Systems (CEMS) to track pollutants.
  • Installed Flue Gas Desulfurization (FGD) systems in 23 units, with ongoing installation in 119 more.
  • Scope 1 emissions increased due to additional thermal capacity, but specific emissions intensity decreased.
  • Scope 3 emissions have been reduced due to decreased coal imports.
  1. Climate Change Mitigation
  • Actively diversifying into renewable energy, nuclear energy, green hydrogen, and biofuels.
  • Planted over 39 million trees since 2016 to build carbon sinks.
  • 8 renewable energy (RE) projects registered under the Clean Development Mechanism (CDM), and 32 projects (6,702 MW) under the Global Carbon Council (GCC).
  1. Biodiversity Conservation
  • NTPC’s projects are not located in protected areas, but some existing stations now fall within eco-sensitive zones due to new declarations.
  • Key conservation projects:
    • Protection of Gangetic Dolphin, Great Indian Bustard, Black Buck, Olive Ridley Turtles.
    • Wildlife Conservation Plan for Sloth Bear and biodiversity mapping at power stations.
    • Mangrove afforestation and compensatory afforestation with ₹7.78 Cr allocated to conservation efforts.
  1. Compliance & Environmental Training
  • NTPC stations are ISO 14001 certified.
  • Undertakes renovation and modernization (R&M) to ensure compliance with environmental standards.
  • Conducts environmental training programs on waste management, water conservation, and biodiversity protection.
