5. Project Rationale
Main market segments for power supply:
โข Telecom power โ reduce cost of remote telecom power by
40%. Provides significant increase in reliability of services.
โข Rural Dairy / Agricultural Supply Chains โ Dairy sector in
Bangladesh is inhibited by lack of supply chain infrastructure
including cold storage and power
โข Remote Consumer / Light Commercial Power for hotels,
hospitals, innovative small commercial operations that require
less than 10 kW of reliable, continuous power

7. Risks and Mitigation
Risks Mitigation
Fuel Availability Need regular supply of waste in excess of 1 ton per day. Farmer
to invest for active involvement; Engine can run on multi-fuels to
ensure operations 24/7
Cost of Engine Manufacturing in India and volumes would drive down costs
Credit Risk Agreed tariffs with telecom operators on long-term
Pre-paid electricity for consumers
Telecom
companies
Bangladesh telecom companies are profitable; Multiple operators
expressed interest to implement renewable energy solutions
Site Selection Management has deep understanding and experience;
have past set up nation-wide operations;
Cooling Solution Explore to commercialize solution to for additional revenues from
the existing installations
Digester
Maintenance
To invest in low maintenance digesters which accepts multi-
feedstock.
Control over
Engines
Remote control and analysis of engines possible, by available
built-in CPU and utilizing access to telecom

โข Initial 1 kilowatt prototype in Bangladesh operated 5+ hours /
day for 6 months powering telecom tower + power to
consumers from 1,200 bird chicken farm.
โข Commercial 5 kilowatt demo unit deployed Nov 2014 to supply
24/7 power to telecom and consumers from biogas
โข In discussions with IDCOL, Bangladesh energy financing
group backed by Asian Development Bank, to provide
financing for farmerโs investments
โข Formal expression of interest (MoU) for orders from
Grameenphone, largest telecom company. Pilot-Phase
Cooperation at 3 selected telecom sites

11. Impact vs. Solar
โข EBI installations provide the
following community benefits not
possible through solar installations:
โข Job creation through processing of waste
โข Direct payments to farmers for biogas
production (increasing the productivity of
existing farms)
โข Reduction of methane emissions in
atmosphere through processing of
biomass into biogas
โข Removal of pathogens through
remediation of waste in digester
โข 24/7 operation, no intermittency issues,
no need for diesel backup
11
12. Impact vs. Solar (cont.)
โข EBI installations add-ons:
๏ท Production and sales of organic fertilizer
provides manual human healthy works
๏ท Locally produced organic fertilizer replace
energy intensive chemical fertilizers
๏ท Procedures by handling of manure leading
to improved animal welfare and hygienic
conditions for farmer and hurdle
๏ท Heath converted to cooling at the farm
will improve food condition and quality
๏ท Excess Gas volumes may be used for
cooking, instead of firewood that pollutes
both air and human lounges
