4. Market for Distributed Micro-Power
• Only 41% people have
access to Electricity*
• Per capita electricity
consumption is 279 kWh*
• Pre-paid electricity is
increasing in popularity
• < 50 kW generation is
unregulated
• High availability of biomass
feedstock (cattle and agri
waste) across country

5. Core Technology
• Micro-Combined-Heat-and-Power
(micro-CHP) Cogeneration
• External combustion, can run on
• biogas / biofuels
• any liquid or gaseous fuel
• Continuous Operation 24/7
• > 70,000 hours lifetime (compared
to 5,000 hour for diesel generator)
• No noise, < 60dBA
• Low Maintenance
• 3.5 to 7.5 kW electric + heat
• Heat to be used for cooling

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

8. 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

• 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.
• Commercial 5 kilowatt demo unit deployed Nov 2014 to supply
24/7 power to telecom and consumers from biogas
• In discussions with IDCOL, Bangladesh energy financing
group backed by Asian Development Bank, to provide
financing for farmer’s investments
• Formal expression of interest (MoU) for orders from
Grameenphone, largest telecom company. Pilot-Phase
Cooperation at 3 selected telecom sites

13. Impact vs. Solar
• EBI installations provide the
following community benefits not
possible through solar installations:
• Job creation through processing of waste
• Direct payments to farmers for biogas
production (increasing the productivity of
existing farms)
• Reduction of methane emissions in
atmosphere through processing of
biomass into biogas
• Removal of pathogens through
remediation of waste in digester
• 24/7 operation, no intermittency issues,
no need for diesel backup
13
14. Impact vs. Solar (cont.)
• EBI installations add-ons:
Production and sales of organic fertilizer
provides manual human healthy works
Locally produced organic fertilizer replace
energy intensive chemical fertilizers
Procedures by handling of manure leading
to improved animal welfare and hygienic
conditions for farmer and hurdle
Heath converted to cooling at the farm
will improve food condition and quality
Excess Gas volumes may be used for
cooking, instead of firewood that pollutes
both air and human lounges

15. Farmer’s Pilot Objectives:
• Find optimal build principle and materials for power plant
building and biodigester
• Find optimal mix of waste ingredients and test add-in of
materials to obtain maximum biogas production
• Determine the market price for biogas
• Identify potential farmers to sell off overload of fertilizer
• Investigate market for commercial fertilizer sales
• Explore potential of maintenance support for EBI & MNO
(power/telecom)
15
16. EBI’s Pilot Objectives:
• Validate business model and technology
• Determine commercial applications for power including
irrigation pumping, ICT applications, electric devices battery
charging and other revenue generating services
• Learn the requirements and costs for mini-grid deployments
and associated (pre-) payment transactions for customers
• Validate seamless shift in fuel alternative supply, continuous
24/7 power supply – minimize engine stoppage time/year
• Determine price of power required for adequate financial
returns and overall company scalability
• Cooperation for synergies w/externals like Vekst Foundation
16
17. MNO’s Pilot Objectives:
• Operational expectations and experience from each power
plant site. Potential testing of hybrid solutions
• Remote access for verification and management of
operation, potential on site maintenance coop with farmer
• Validation of business case, decrease opex and power cost,
increase site reliability and service availability to 99.5%
• Improvement in relations with local communities where cell
towers are located. Recognition of social responsibility
• EBI coop to explore potential sites for commercial phase
