As per the cogeneration association of India, there are many industrial sectors that have good potential for cogeneration. Industrial units in following sectors should take advantage of cogeneration technology – Sugar, Paper, Oil Extraction, Urban Waste Treatment, Forest based Industries, Chemicals Fertilizers, Metallurgical Industries, Textiles-Cotton & Synthetic, Hotels, Rice Milling, Food Processing, Rubber Industries, Petroleum & Refineries and Malt & Brewery Industries.
In Maharashtra, most of the cogeneration plants are developed by Sugar factories as they have enough quantity of bagasse – a by product of sugar production. Therefore mostly all sugar factories involve cogeneration system which use bagasse as fuel (renewable source of energy) in order to meet power and steam requirements of the production process. Besides this, it also provide excess power to the grid or use for other purpose like captive consumption for other industrial use.
Promotional policy for the cogeneration and other biomass based power projects by the Government
- Indian Renewable Energy Development Agency (IREDA) provides loan for setting up biomass power and bagasse cogeneration projects.
- The Ministry of New & Renewable Energy (MNRE) GoI, has been supporting the Cogeneration power projects by giving back ended subsidy. The 50 % subsidy will be released for sugar factories developing Cogeneration power projects in cooperative sector / public sector /government under taking/ SPV company (Urja Ankur Trust) through BOOT model after issuance of purchase orders for larger equipments like boiler, turbine etc. The remaining 50 % subsidy could be availed after commissioning of the project and demonstrating its continuous operation for 90 days (3 months) from which 72 hours the plant should run with 80% PLF.
- For private sector, a one time subsidy will be released after commissioning of project after assessment of performance of the plant.
Overview of Renewable Energy Certificates: Renewable Energy Certificates are a type of environmental commodity intended to provide an economic incentive for electricity generation from renewable energy sources. One REC is created when one megawatt hour of electricity is generated from an eligible renewable energy resource. REC represents the environmental attribute associate with unit of power produced.
Eligibility of cogeneration power plants under the REC mechanism: If sugar mill has a biomass cogeneration based power plant, they are eligible to earn RECs subject to these power plants are grid connected and have PPA with DISCOM at APPC price (As per the CERC guidelines, the power producer has to sign a PPA with the state utilities at a price equal to the Average Power Purchase Cost price. The APPC price for a state for a particular time period is determined by the State Electricity Regulatory Commissions). Grid connected cogeneration power plants that provide electricity for captive uses are also eligible to earn RECs.
Following points will elaborate about the procedural requirement for biomass cogeneration plants under the REC mechanism –

There are many benefits of cogeneration power plant. They not only provide clean power but also help project developer to become economical by drawing two form of energy. In addition, cogeneration based power plant based on renewable energy sources (biomass) as fuel, does not affect the ecology, provided a few precautions are taken in the design of the plant. Project also reduces pollution levels in the surrounding area as compared to conventional power plants.
