Overview
Environmental Power Corporation (“EPC”) owns and
operates proven commercial scale renewable energy
facilities producing a versatile methane-rich biogas
from waste products consisting of agricultural livestock
and other organic wastes.
EPC has a proven track record and is a leader in the biogas
based renewable energy market and evolving carbon credit
market.
Market Drivers
First Mover Status
Unique Offering –
Projects “Ready to Go”
Unique opportunity to provide project dedicated funds at a
market coupon rate and participate in equity upside.
High and volatile energy prices, growing renewable energy
demand (RPS), increasing environmental concerns (carbon
emissions) and increasing regulation of agricultural waste
have led to increased interest in EPC’s renewable product.

Advantages of Biogas
4
Versatility
Income
Alternative
Security of
Supply
Biogas can be used to displace an
array of conventional fuels.
Infrastructure already exists vs.
other renewables
Provides income diversification and
cost savings for farmers
Reduces dependence on fossil
fuels and is a domestic supply of
energy
Produces energy when needed,
rather than when available
unlike wind & solar which are
intermittent
High
Economic
Efficiency
Does not require government
subsidies
Production efficiency is
significantly higher than other
biofuels
Addresses farms nutrient
management concerns.
Biogas process sequesters
methane; 21 times the effect
of carbon dioxide as a
greenhouse gas
Waste products (manure and
other organic wastes) are the
feedstock; not dependent on
food crops
Non-depleting asset utilizing
waste streams
Good for
Environment

Confluence of Agriculture and Energy
Agriculture
Outsourcing of manure management issues
Alignment of Long-Term Interest
Reduced farm operating/capital costs
Lease payment for the site of facilities
Project profit sharing with local farmers
By-products can be used as bedding for animals and liquid fertilizer add value to
farm; potential third party sales
Energy
Useful renewable energy product (Renewable Portfolio Standards, state mandates,
Renewable Energy Credits, etc.)

Most projects expected to qualify for salable carbon credits

EPC produces pipeline-quality natural gas . . . with renewable attributes
EPG is essentially a renewable exploration
and production natural-gas company with
some key differences:
-
No exploration risk
-
No drilling risk
-
No dry holes
-
Non depleting resource
Also an active participant in the evolving
carbon credit market

Project Economics Highlights
Long/Medium Term Natural Gas Sales Agreements
We use
long/medium
term
gas
sales
agreements
with
fixed
prices
recognizing
“green”
value
of our gas to provide certainty of revenue streams
Carbon Credit Revenue Opportunity
In the
current
US
voluntary
market,
we
see
$2.00
to
$7.00/metric
ton
depending
on demand.
Utility executives planning on $12 to $30/metric ton under proposed mandatory markets –
market will dictate price
Typical, lagoon-based
635,000
MMBtu
project
is
expected
to
produce
75,000
250,000 metric
tons of carbon offsets per year, depending upon final protocols
Waste-Based Feed Stocks Used to Create Biogas
Manure  –
we typically get manure for free from the farm or industry
Substrate (organic materials) –
we pay transport but may get tipping fee for partial offset
Potential By-product Value
Solids –
third party discussions as a peat replacement or as an eco-friendly building product
Liquids –
fertilizer
without
odors,
seeds,
pathogens
and
in
more
suitable
form
to
meet permit
requirements

Debt Convertible into Common Equity

Fixed Rate
Liquid
Security
Senior to All
Equity
Dedicated
Project
Funding
Fixed rate debt fully registered
with the SEC and unrestricted from
trading
Debt has seniority in the holding
company capital structure, ahead
of the existing convertible
preferred stock and common stock
With $130 million in project
financing already raised, money
raised in this offering will go
directly to facility
construction/operations
Contractors pre-qualified,
permits obtained and site
arrangements secured for the
next seven projects
Convertible
Equity at
2008 Price
Debt convertible into common
equity at a minimum
conversion price achieved in
summer 2008
When construction of the seven
permitted facilities is complete
(anticipated to be in 2010),
EPC annual revenues expected
to be greater than $40 million
Likely transition to mandatory
market could significantly
increase EPC revenue opportunity
US dairy, cattle and hog farms
