Bio Energy


Biomass has always been an important energy source for the country considering the benefits it offers.  It is renewable, widely available, carbon-neutral and has the potential to provide significant employment in the rural areas.  Biomass is  capable of providing firm energy.  About 32% of the total primary energy use in the country is still derived from biomass. Ministry of New and Renewable Energy has initiated a number of programmes for promotion of efficient technologies for its use in various sectors  to ensure derivation of maximum benefits .

For efficient utilization of biomass, bagasse based cogeneration in sugar mills and biomass power generation / co-generation in industries have been taken up under biomass power and cogeneration programme.

Biomass power & cogeneration programme is implemented with the main objective of promoting technologies for optimum use of country’s biomass resources for grid power generation and captive power production.  Biomass materials  used for power generation include juliaflora, bagasse, rice husk, straw, cotton stalk, coconut shells, soya husk, de-oiled cakes, coffee waste, jute wastes, groundnut shells, saw dust etc.

Biomass  Gasifier


Grid connected Biomass Gasifiers in the state

  • M/s. Sri Saastha Energy Pvt Ltd, Vellore – 0.5 MW (2010)
  • M/s. Arasi Hitech Bio Power Pvt Ltd, Coimbatore – 1 MW (2003)

Biomass Gasifiers can be deployed for meeting thermal energy requirements in various industries viz., Rice mills, jaggery, textile and dying, tiles, steel and other industries Biomass gasifiers can be utilized for Grid interactive/ Off grid power wood firing .generation. Biomass gasifiers consume less biomass fuel compared to conventional wood firing.

MNRE/GoI provides subsidy for the following

  • Biomass Gasifier based Distributed / Off-grid power programme for Rural Areas.
  • Biomass Gasifier based Grid Connected Power Programme
  • Biomass gasifier based programmes in Rice Mills

Biogas Plants



A combustible gas (composed primarily of methane) produced when Organic waste, sewage or manure is fermented in the absence of oxygen. The solid material that remains in the digester after fermentation can be used as an organic fertilizer.

Biogas – a gas mixture of methane, carbon dioxide and small quantities of hydrogen and hydrogen sulphide – is created under air exclusion through the fermentation of organic substances with microorganism assistance. Biogas is a gas mixture, consisting of approximately 40 to 75 % methane (CH4),  25 to 60 % carbon dioxide (CO2), and approx. 2 % of other gases (hydrogen, hydrogen sulphide and carbon monoxide).

Advantages of Biogas

  • No smoke ,  Clean Fuel
  • Produces organic manure for a sustainable agriculture
  • It reduces fossils fuels Dependency

MNRE provides subsidy towards establishment of Biogas Based Power Generation Systems vide the following:

  1. Continuation of Biogas based Distributed / Grid Power Generation Programme during 2010-11 – Administrative Approval –
  2. Implementation of National Biogas and Manure Management Programme (NBMMP) during 11th Five Year Plan – Administrative Approval – addendum reg.
