Ministry of New and Renewable Energy
(Bio-Energy Technology Development Group)
Scheme: Biogas based Distributed / Grid Power Generation Programme
Biogas technology provides an alternative source of energy mainly from organic wastes. It is produced when bacteria degrade organic matter in the absence of air. Biogas contains around 55-65% of methane, 30-40% of carbon dioxide and small quantities of Hydrogen, Nitrogen, Carbon Monoxide, Oxygen and Hydrogen Sulphide. The calorific value of biogas is appreciably high (around 4700 kcal or 20 MJ at around 55% methane content). The gas can effectively be utilized for generation of power through a biogas based power-generation system after dewatering and cleaning of the gas. In addition, the slurry produced in the process provides valuable organic manure for farming and sustaining the soil fertility.
The Ministry has started a scheme “Biogas based Distributed / Grid Power Generation Programme” from 2005-06 (4th January 2006) with a view to promote biogas based power generation, especially in the small capacity range, based on the availability of large quantity of animal wastes and wastes from forestry, rural based industries (agro / food processing), kitchen wastes, etc.,
The objectives of programme are as follows:-
(i) Biogas based power units can be a reliable decentralized power generation option in the country. In order to promote this route of power generation, specifically in the small capacity range (3 kW to 250 kW), based on the availability of large quantity of animal wastes and wastes from forestry, rural based industries (agro/food processing), kitchen wastes, etc;
(ii) A number of projects of different capacities and applications will be takenup for refining the technical know-how, developing manpower and necessary infrastructure, establishing a proper arrangement of operation & maintenance and large scale dissemination.
(iii) To mitigate Climate Change by preventing black carbon and methane emissions.
1.3 Implementation strategy:
The programme would be implemented through nodal departments / agencies of the States / UTs, KVIC, institutions and NGOs. The projects to be taken up by any village level organization, institution, private entrepreneurs etc in rural areas as well as areas covered under the Remote Village Electrification (RVE) programme of MNES other than the industries and commercial establishments covered under Urban, Industrial & Commercial Applications (UICA) programmes for sale of electricity to individual / community / grid etc. on mutually agreeable terms. Installation of projects will be encouraged only if specific responsibility is taken upright from the initiation of project by the institution including for operation and maintenance for the specified period as per DPR norms or otherwise for a minimum period of ten years.
1.4 Training & Awareness Promotion
The programme provides support for a variety of workshops, seminars, meetings, training programmers to the implementing agencies/specialized organizations/Biogas Development & Training Centers (BDTCs) for developing the required specifications and standards, discussions/deliberations on the performance of systems, setting up operation and maintenance mechanism, training of required manpower, capacity building, business meets for the prospective industries, etc. with the ultimate objective of promotion of power generation based on biogas in the country.
The quantum of financial assistance to be provided by Ministry of New and Renewable
Energy (MNRE) for conducting these programmers will be decided on the basis of nature & duration of the programme, number of participants, etc. The maximum assistance, however, is limited to `1,00,000 per event.
The central financial assistance for such projects will be limited to a maximum of Rs.30000 to 40000 per kW depending upon capacity of the power generating projects in the range of 3 kW to 250 kW of different rating limited to 40% of the plant cost.
|Power generating capacity||Biogas plant capacity||Maximum support for preparation of DPR||CFA/subsidy limited to the following ceiling or 40% of the cost of the system whichever is less.||Administrative Charges to State Nodal Department / Agencies/BDTC’s for providing technical, supervision, training support and to initiate action on power purchase agreement with state electricity board/power purchasing companies and submission of project completion and monitoring report of successful operation.|
|3-20kW||25 M3 to 85 M3||No DPR required||Rs. 40,000 per kW||15% of the CFA (up to 20 kW capacity for which no assistance for DPR is provided),|
|>20kW up to 100kW||Any combination of above plants or approved alternate capacity / design||Rs. 20000 per plant||Rs. 35,000 per kW||10% of the CFA (> 20 kW - 250 kW)|
|>100kW up to 250 kW||Any combination of above plants or approved alternate capacity / design||Rs. 1,00,000 per plant above 100 kW||Rs. 30,000 per kW|
The programme provides support for a variety of workshops, seminars, meetings, training programmes to the implementing agencies / specialized organizations / Biogas Development & Training Centres (BDTCs).
1.6 Pattern of Release of funds:
Central Financial Assistance (CFA) for projects and service charges to State Nodal organizations/implementing agencies/BDTC’s are given at Annexure-II and pattern of release of funds would be as follows:
- 50 per cent of the eligible CFA and service charges will be released to the State Nodal Department/Agency/organization/BDTC’s with the sanction order.
- The balance 50% of the eligible CFA and service charges will be released after successful commissioning of the biogas power plant as per the DPR norms (wherever DPR is required), receipt of utilization certificates, audited statement of expenditure. Project on completion, requires inspection report submitted to MNRE by an authorized agency of MNRE .The condition of successful commissioning of the plant would, inter-alia, imply generation of power with operational capacity of 10 kWh/day/kW of sanctioned capacity for 3 consecutive days.
- In case the project is set-up by the developer through his own resources, the entire eligible CFA could be released to the project developer after receipt of the successful commissioning and operational report from MNRE state Nodal departments/ Agencies, KVIC and BDTC’s along with other documents and meeting conditions as mentioned under para 4 (ii) above.
- For preparation of DPR for power projects, (wherever required) and for programmes relating to Training & Awareness Promotion, 50% of the eligible CFA will be released to implementing organizations along with the sanction order. The balance will be released on receipt of the utilization certificates, audited statement of expenditure and the final report at the time of final acceptance and settlement of the expenditure account of the project as per the approved norms.
1.7 Monitoring Mechanism
Monitoring of the Bio-gas based power projects would be done based on half yearly/annual progress reports as well as monitoring by SNA/ an authorized agency of MNRE. The project developers would extend all help required in monitoring of the projects.
