Pioneer Renewable Energy Project Overview June 2009

Project Overview Madera Energy, Inc. is developing a biomass power plant, called Pioneer Renewable Energy (PRE). PRE will be located on ~65 acres in Greenfield, MA. Capacity of the project is 47 megawatt (“MW”), which will generate nearly 400,000 MWh of renewable electricity per year for sale into the wholesale market. This is equivalent of powering more than 45,000 homes (or >150% of the households in Franklin County). Project cost is expected to total approximately $250M. It is expected that development will take ~18-24 months and construction will take ~30-36 months. The project will result in hundreds of jobs for Greenfield and the surrounding community, as well as millions of dollars in additional economic activity.

What is Biomass Power Biomass power is the conversion of organic material (trees, plants, or other sources) into electricity. Biomass is a renewable source of energy. In utility- scale applications, the electricity is sold to the wholesale market (also known as the “grid”). Biomass power is CO 2 neutral (or a “low carbon alternative”) and therefore an important tool in combating climate change. Biomass Material Wood Chips Power Plant Transmission Lines (“the grid”) Consumers

Why Greenfield The Greenfield site is located close to major roads, would have little to no impact on residential areas, has sufficient water and other utilities, has three transmission lines that pass through the site, is located in an excellent wood resource area, and has sufficient land.

Why Biomass High Energy Prices (and Rising) Economic Development Climate Change Concerns Energy Security Environmental Stewardship Resource Availability

Why Biomass – Economic Development According to a study conducted by UMASS Amherst, the MA DOER, and the MA DCR, the development of biomass energy “holds substantial economic promise”. Study shows that 165 MW of new biomass results in thousands of jobs and billions of dollars in economic output.

Why Biomass – Economic Development A 47 MW facility would make a significantly positive impact on the local economy.  permanent, direct employment opportunities  project-related jobs for local businesses, including foresters, loggers and truckers  construction jobs over the month construction period  ~$250M facility would significantly add to the local tax base  Additional revenue to the DPW (new water and sewer fees)  Create market for low-grade wood Create demand for ~500,000 tons of clean wood fuel annually  Support potential renewable energy “cluster”  Act as a “magnet” for additional industrial development  Provide region with reliable, economical, and sustainable energy

Project Overview  47 MW power generating facility (net) Generate nearly 400,000 MWh of power Enough to power the equivalent of ~45,000 homes - equivalent to powering >150% of the households in Franklin County  Low emission advanced biomass conversion technology Qualifies as renewable energy under federal and state requirements  Fuel consists of ~500,000 tons per year of clean wood NO painted or treated wood – permits/economics don’t allow it  Truck Traffic – Draft of traffic study complete Average of ~60 truck loads per day (120 truck trips) Significant truck traffic already travels thru Adams Rd/Route 2 intersection  Total project cost -~$250,000,000  Stack height of 250’(not highest structure on property)

Where the Fuel (Clean Wood) Comes From Massachusetts is the 8 th most forested state in the country, with forest-lands constituting more than 3 million acres (or >62% of the land).  Commercial Forest Operations Clean, low-grade material from commercial operations – normally remains in the forest  Timber Stand Improvements Clean, low-grade material from conservation lands managed for environmental or wildlife purposes and “cleaning cuts” on commercial forest lands.  Clean Wood Waste Clean wood waste from real estate development (land conversion), ice storms, transmission lines, municipal trimmings, etc. NO PAINTED OR TREATED MATERIAL.  Secondary Wood Manufactures Clean wood waste from sawmills, pallet recyclers, etc.

Sustainable Fuel Supply The area surrounding the proposed site has a rich supply of wood. A study performed INRS estimated that new growth of biomass exceeds harvest and mortality by >3M tons per year.

Sustainable Fuel Supply There is very little current demand for low grade wood within a 55 mile radius of Greenfield, which makes the site a very attractive location for a biomass facility. Source: INRS Greenfield, MA

Project Overview – Technology Pioneer Renewable Energy will utilize advanced biomass conversion technologies, including state of the art emission control systems and an advanced stoker boiler.

Project Overview – Air Quality Pioneer Renewable Energy has performed an air modeling analysis and results show that air quality, with or without the project, will remain essentially unchanged.

Project Overview – Air Quality Pioneer Renewable Energy has performed an air modeling analysis and results show that any impacts of emissions from the stack will be below Significant Impact Levels (SILs). SILs are the EPA- defined levels under which impacts are considered insignificant. The SIL is 2 micrograms per cubic meter of air, or ug/M3 for PM 2.5.

Air Quality - Comparison to Wood Stoves Particulate emissions from PRE will be nearly 150 times lower than a typical residential wood stove.

Air Quality - Biomass vs. Coal PollutantMt. Tom Pioneer Renewable Energy lbs/MWh SO2 (pre Mt. Tom upgrade)90.33 SO2 (post Mt.

After upgrades currently underway, Mount Tom will continue to have emissions nearly 3 times higher than Pioneer. Sources: Mt. Tom emissions based on discussions with plant manager, recent regulatory approvals, and standard EPA factors. PRE emissions based on proposed permit limits.

Project Overview – Traffic A detailed traffic impact analysis conducted for the project concluded that project-generated traffic will utilize well-established truck routes and will not negatively impact area roadways and intersections.

Project Overview – Water & Utility Information  Water Wet cooling would require estimated ~700,000 gpd % for cooling, % for boiler/potable Source of cooling water will be grey water from treatment plant – located 5.1 miles away – will access via Town roads ~49,000 gpd of water needed for boiler make-up will come from an on-site well  Sewer - Water discharged into sewer system  Will provide additional ~$250,000 per year in water/sewer fees to the DPW  Will use diesel for start-up  On-site ammonia tank (for emission control)

Project Overview – Wood Ash About 2% of the wood will end up as ash. The ash can be used as an organic fertilizer and is very well suited for Pioneer Valley soils.  Will likely use a firm by the name of Resource Management, Inc.  Certified organic  Clean wood ash is cost effective and well-suited to the soils of the Pioneer Valley  High in potassium and lime  Also acts as another safeguard against using painted and treated wood as every load of ash will be tested

Project Overview – Thermal Energy PRE has incorporated the ability to generate thermal energy into the design of the facility. The type of thermal energy will depend on the needs of potential customers.  Thermal energy could constitute hot water and/or steam  Would increase the efficiency of the facility, therefore further increasing the facility’s environmental benefits and economic viability  Provide low cost heating and/or cooling to businesses in the industrial park and surrounding community Madera Energy has reached out to a number of organizations to inquire about complementary uses  Examples of businesses that can make use of thermal energy: Steam – Biotech, manufacturing, food processing Hot Water – Greenhouses, residential, office buildings, aquaculture, algae farms, District Heating
