NETPRO biomass plant
D.E.S.I. Power & NetPro Renewable
Fabricated by Neptro and distributed by DESI Power in India, this is a Biomass Gasification Power Plan with an output capacity from 20 kW to 1.2 MW.
Organizations: DESI Power, DASAG Energy Engineering, Government of India and TARA (Technology for Action and Rural Advancement), Village EmPower Partnership Programme and Smart Power for Environmentally and Economically Sound Development (SPEED).
CDF report (2011), claims costs of 55,151 USD for 75kWe plant.
Investment requirements listed by DESI: Rs. 4,000,000 (100,000 USD) per 50 kW plant. DESI’s installations typically cost 200,000 USD, 60% of which pays for the plant, 30% for enterprise development, and 10% for capacity building and training. DESI’s optimal investment structure is a 50% equity base, a 10% subsidy it automatically receives from the Indian government for delivering renewable energy, and a 40% loan which is paid back over 7 years.
Flexi Biogas; Husk Power Systems; Simgas, TINY Tech biogas plant.
Goal 7: Ensure access to affordable, reliable, sustainable and modern energy for all.
Target users are off-grid communities (households) and in particular the micro-enterprises & industries in Bihar and across rural India that need electricity.
Plants are designed and built individually depending on demand and fabricated by Netpro.
IP Protected (Patent Unknown).
Not available as of 2018, but previously available through DESI/NetPro.
14 (as of August 29, 2012), final number of distributions is unknown.

• Guidance for Energy Plantation
• Plant’s rated capacity: 20 kWe to 1.2 MW
• Biomass requirement generated : 1 kg per unit of electricity
• Land requirement (space): 700 m2 (with 400 m2 of covered
Additional performance data here.
Avg. DESI Power Raw Material Consumption/Hour = 50-70 kg (75 kWe plant)
Capital costs for a plant of 50 KWe capacity is $1400/KW (2007 numbers)
CDF Report examines DESI and Husk Power in: Technology Type, Area and End-User profile, Cost of Establishment and Operations, Feedstock Supply Chain, Distribution and Revenue Collection, Pricing Strategy and Managment Team and Man Power. They conclude that both systems/ organizations have advantages as the focus on slightly different clients, financing, structure and type of biomass used. The biggest comparison financially is that the minimum monthly payment required for electricity from DESI Power plant is approximately Rs. 100 – In contrast, a household in a village where Husk Power Systems operates can get the same amount of electricity for half that price.
Other reports/organizations (Rockefeller and Gates Foundation) appear to focus even more on financial benefits of the decentralized energy system, i.e. cost per kW/h, not on all of the details of technical performance or a particular location/system.
The CDF report (Center for Development Finance and IFMR Trust) examined DESI Power operations at Baharbari, Bebhra, Gaiyari in Araria district.
There can be dangers operating a biogas systems during the operation of machinery, the event of a malfunction (voltage, handling Hydrogen and Carbon Monoxide), and in handing residue/by-products.
Increasing efficiency and versatility of biomass energy consumption, or pairing biomass with PV and/or Wind to optimize energy production.

Evaluation method by (2011) CDF Report which examined DESI and Husk Power looked at: Technology Type, Area and End-User profile, Cost of Establishment and Operations, Feedstock Supply Chain, Distribution and Revenue Collection, Pricing Strategy and Management Team and Man Power.
In terms of technology development/testing it appears the evaluation is done through NetPro and DESI. The evaluation methods in general appear to be very focused on the financial analysis of power outputs, hours of electricity provided and entrepreneurial opportunities. Pages on DESI/ NetPro site have cost breakdowns, and report by Gates’ Foundation (donor to SPEED which DESI is part of) also talk mainly of this cost-benefit.
