“Creating Energy Solutions from Biomass Waste”
2
A Renewable Energy Project Development Company focused on providing the best renewable energy solution to match customer & project needs
BG&E projects use “advanced gasification” technologies
BG&E has an extensive Knowledge of the top gasification processes currently available
BG&E’s experienced development and management team:
Has over 60 years in the industry and over 4000 MW installed/managed.
Principals developed & operated the largest advanced gasification facility in the U.S.
BG&E project benefits include:
Off balance sheet benefits for inside the fence and external energy projects
No capital outlay by the client
Clean renewable energy with lowest emissions
Long-term predictable energy costs

Process Output History
→ Longest History→ Highest level of Pollutant
i.e. 250tn for 20MW→ No Fuel Flexibility
→ Latest Advancement (10+ years)→ Lowest possible emissions
i.e.10 to 50tn for 20MW→ Widest range of fuel flexibility
→ Extensive history & use→ Controlled Emissions
i.e. 50 to100tn for 20MW→ Limited Fuel Flexibility
→ Short History (30+ years)→ Controlled Emissions
i.e.50 to 100tn for 20MW→ Limited fuel Flexibility

Gasification – A Proven Technology

Advanced Gasification Technology – Key Points
Standard gasification is a high heat partial burn process which breaks down feedstock into it’s basic gaseous elements
Advanced Gasification is a pryolysis process without oxygen or burning which:
offers up to 35% greater efficiency over stoker technology
Produces a reduced emission of 98% below conventional fossil fuel plants & 40% below conventional biomass plants.
Can accommodate a variety of organic feedstock of varying moisture content without impacting Btu content.
Gasification to advanced gasification improvements have been provided by world renowned programs such as: Battelle Labs, NREL, U.S. Department of Energy
At completion, the biomass material is reduced to a minimal inert ash residue with multiple commercial use. (road bed material, landfill fillers, fertilizer extenders, etc)

When additional or replacement fuels are required:
Advanced Gasification = More Fuel Flexibility
“Clean” C&D debris – Includes road & land clearing debris, industry waste (palates, sawdust, paper waste, etc), felled storm debris, urban biomass wastes
• excludes painted and CCA treated wood
Forest Wood Waste – supports proper forest management, is easily processed, and offers good BTU value
Rice hulls & bagasse – an excellent fuel source and beneficial alternative to burning
Energy Crops – such as switch grass and Arundo Donax • Can be grown providing a stable fuel source• provides new industry opportunities
Chicken litter and agricultural waste offer:• high output feedstock• ash becomes usable fertilizer• removes land spread issues
7
Process Flow• Organic feedstock at 3”-
is fed thru a hopper and through an air lock
• In the air lock nitrogen purges out the oxygen
• Blended with steam the feedstock is mixed with 18000f heat
• As the heat mixes an instantaneous reaction “gasifies” the feedstock breaking it down into it’s basic elemental gases
• Cyclones separate the Syngas and any Char
• Gas & char is burned in the combustor generating heat sent to the gasifier

Development Milestones of the Forsyth Project
EPC• Experienced contractor selected
• Project contract includes schedule & performance guarantees
• Market driven liquidated damage requirements
• Shared savings contract to support schedule.
Permit• Site-specific Engineering completed
• Emission Modeling
• Application made within 90 days of PPAFinancing• Checklist completed to achieve financing
• Closing set to follow receipt of final air permit and interconnection agreement
Feedstock Contracted• Multiple contracts to be signed by using the advantage of below market landfill rates
Permanent financing completed
Equipment Ordered
Construction Ground-breaking• Site work commences
Project Site• In escrow pending financial close
Project shakedown• Systems performance tested
• Output, emissions, feed systems all tested to spec.
• Following acceptable runs –BG&E begins PPA services
Permitting review• Local and federal requirements reviewed during PPA/EPA stage
• Emission requirements & limits
• Other permit issues
Feedstock identified• Preliminary Analysis for availability and cost
• Market research identified 300+% of project requirements
Project Site• Access to required interconnects & utilities
• Preliminary zoning review
• Acquisition terms negotiated and site closed in escrow
PPA Developed• Financial modeling
• Equipment identified and preliminary bids received
• BG&E worked with the Georgia Public Service Commission and Georgia Power to develop a market driven pricing structure called the “Proxy Pricing Formula”
PPA completed* Air Permit received Construction Completed

Forsyth Power Project – Solutions
Forsyth Virtual Street View
PPA – 20 year - 28 MW net to the grid under a with the financible buyer - Georgia Power Company
Equity Partner to purchase Production Tax Credits
EPI/InDeck supports:
Fuel Flexibility
Permit Constraints
EPC & Construction Schedule
Zoning limits feedstock receipt & processing to “daytime” only
EPC commitment to “fully wrap” project

Forsyth Power Project – Technology Emission Driven
BG&E selected technology is an EPI starved air fluid bed gasifier coupled with an InDeck recovery boiler.
Back-end emissions controls include a hot ESP followed by a CO2 catalyst and SCR to manage NOx
540 DTPD produces 268 MMBTU/Hr of steam at 9500 F and 1215 psi which directly feeds a 32 MW STG
Project Construction time is 15 to 18 months from ground breaking thru commissioning
12
Technology Supports Feedstock Sources
Extensive private and public studies provided initial support for project and indicated what, where and how much was available.
Selected Feedstock: “Clean” C&D debris – industry waste (palates, sawdust, paper waste, etc), forestry mgmt waste, felled storm debris, urban biomass wastes (from land clearing, landscaping, trimmings, yard biomass, etc), creosote treated woods (telephone poles, RR Ties, etc),
• excludes painted and CCA treated wood
Future Fuel Alternatives
Chicken litter and agricultural waste offers:• high output feedstock• ash becomes usable fertilizer• removes land spread issues
13
Location and partnership with local landfill provides:
Ability to manage landfill tipping fees to attract local wood waste for feedstock
21 days of covered fuel to allow natural drying and plentiful onsite reserves
potential added revenue (from tipping fees) to offset project fuel processing costs
Provides existing staff (at landfill) reducing project fuel management
Solution for ash residue from project
