Current projects include:

Greensburg Wind Project

On May 4, 2007 at about 9:45pm, a massive tornado leveled Greensburg, Kansas, destroying 95% of the town and leaving a path of devastation nearly 2 miles wide.  In the days that followed this catastrophe, the people of Greensburg individually and collectively agreed to rebuild their town as a green town.

The town developed a new wind farm with critical upfront financing from NativeEnergy.  The Greensburg Wind Farm provides significant economic and environmental benefits for the City as the community continues to rebuild.  The wind farm generates enough energy to power 4,000 homes – enough electricity for every home, business, and municipal facility in Greensburg.  Excess electricity is sold back to the local utility.


Noblehurst Dairy Farm Methane to Energy

Noblehurst Dairy in Linwood, NY has constructed an anaerobic digester for manure conversion and on-farm electricity generation.  Noblehurst is a family-owned farm, with a herd of approximately 1,450 milk cows.

The digester generates approximately 1500 kWh/day, all of which is used to power farm operations. This methane digester avoids emissions of carbon dioxide and methane in two ways: by displacing local grid-based electricity with renewable energy and avoiding methane emissions from manure that otherwise would have been stored in a lagoon by “digesting” the slurry to generate electricity.


Projects funded during 2008 and 2009 included:

Brubaker Farms Anaerobic Digester Project

The Brubaker family farm, founded in Mt. Joy, PA in 1929, has a history of environmental stewardship in its farming efforts. The Brubaker family sponsors local events that promote environmental efforts at the farm, and also holds educational tours for local community members. In 2003, NativeEnergy began working with the Pennsylvania Biomass Working Group to help support the state’s digester initiative. In 2004, we began discussions with the farm regarding funding support for their planned manure anaerobic digester project. The farm was awarded grant money from the State of Pennsylvania in 2005 and then funds from the US Department of Agriculture in 2007. Our discussions with the Brubaker’s continued, and after exploring other alternatives, the Brubaker’s selected NativeEnergy to purchase upfront the carbon emission reductions and RECs associated with the operation of the digester and generator. This additional funding from NativeEnergy allowed for the Brubaker family to successfully complete the project financing.

As Michael Brubaker explains, “We were fortunate to receive the two grants, however we were still concerned about the risk involved in the $367,000 remaining in the project. Our farm would be similar to many farms in that it is land rich, cash poor”. Factoring that amount of money into the cash flow drastically affected profitability. When we learned of the potential revenues from the REC and carbon credits, we felt it was the final piece of the puzzle that was needed to go ahead with the project. This final portion of the funding is exactly what was needed to insure a quicker payback and better rate of return without putting an excessive burden of debt on the rest of the farm.”

The Brubaker family farm methane digester produces renewable energy, some of which is delivered to the local electric power grid. The digester also powers a portion of the farm’s operations. Additionally, excess heat from the electric generator engine is used to heat the farm buildings, reducing the farm’s fossil fuel use. Brubaker Farms is among the first to receive the Pennsylvania Environmental Agricultural Conservation Certification of Excellence. The farm received the National Environmental Stewardship Award in 1999 and a major livestock award in 2000.

The project is a good example of a working and successful farming operation that is a responsible steward of the environment, an active member of the local community, and able to co-exist in an area that is experiencing a growth in residential development.


Des Plaines Landfill Project

The Des Plaines Landfill is located in Cook County, Illinois, about 30 minutes northwest of downtown Chicago. The landfill is located at 9800 Central Road between River Road and Interstate 294. The Des Plaines River and a cemetery abut the landfill on the west side, and the Oakton Community College is located across Central Road south of the landfill. Its use as a privately operated landfill began in the early 1960’s, and ceased accepting waste by 1986.

The site is owned by the Archdiocese of Chicago, and was operated by John Sexton Sand and Gravel. The site has a waste footprint of about 130 acres, with an existing waste-in-place volume of about 11.6 million cubic yards. The site accepted municipal solid waste (MSW) throughout its active life. Waste received included small quantities of construction and demolition debris, and some liquid waste. The site is an unlined landfill that was constructed consistent with practices current at the time operations began and therefore without a bottom leachate collection system, geomembrane liner, or a re-compacted soil bottom liner. The natural existing in-situ clay has provided the lining for the landfill. A leachate management system has been installed in recent years. A low permeability soil cover with a minimum thickness of 3 feet was placed over the intermediate cover when the site stopped accepting MSW. The actual soil cover in-place at the landfill is reported to be from 8 feet up to 20 feet in total thickness.

Landfill gas (LFG) is a powerful greenhouse gas. LFG is the natural byproduct of the actions of anaerobic bacteria that cause the organic matter that exists within a landfill to decompose. LFG has the rather consistent composition of 55 percent methane and 42 to 45 percent carbon dioxide with lesser amounts of hydrogen, oxygen, nitrogen and minute concentrations of other gases. The capture of this waste component of the landfill maturation process has considerable environmental benefits. The emission into the atmosphere of LFG is a major contributor to global warming accounting for over 35% of the man-made methane emissions in the United States. The migration of LFG under ground from a landfill can cause groundwater contamination or has the potential to build up in a closed area or a building and become an explosive hazard. The removal of the LFG will facilitate the return of this property to a productive use such as a golf course.

Methane, the major component of LFG, is the principal constituent of natural gas and, therefore, landfill gas is an alternative fuel to natural gas, fuel oil or coal. This waste product can be put to a productive use through the use as fuel for the generation of electrical energy. Power produced and sold from LFG fueled electrical generation facilities is one of the most reliable sources of renewable energy.

Approximately 200 LFG extraction wells are in place covering the perimeter and most interior areas of the Des Plaines landfill. Initially, LFG was collected around the edge of the landfill and then vented to the atmosphere in order to prevent migration of LFG to neighboring properties. In 1998, with the aim to develop an electricity generation project, some of the emissions were collected to measure emissions volume and flow rates. A flare was installed to destroy the LFG until it could eventually be used in a power generating unit.

The emission reduction project, comprising the aggregate LFG collection and destruction capacity operating at the Des Plaines landfill and described in this Exhibit A (the “Project”), now uses most of the LFG to produce electrical energy. By 2002, vertical gas extraction wells, laterals, header lines, condensate driplegs, and a blower/flare unit were installed, and Sexton Energy had replaced the older flare as part of the Project. The replacement utility flare device is located on the south side of the landfill.

The blower/flare unit was installed to collect the LFG from the wells and burn off the collected LFG thus reducing net emissions of LFG. The unit consists of a trailer-mounted 8-inch diameter utility flare with a single centrifugal gas fan-type blower manufactured by Aerovent, and a control panel. The blower is powered by a 50 HP direct drive electric motor. Flow is measured at the flare (and is now measured at the generator, see below) using a flow meter manufactured by the Sponsler Company (Model SP6-CB-PH7-D-4X) rated to measure flows in the range of 250 to 2,900 cubic feet per minute (cfm) as indicated on the flow meter nameplate.

The location supports the Project’s 3500 kilowatt electrical generation facilities. In 2004, operations started to generate electricity using the LFG. A power plant is housed in a building located adjacent to the landfill on land provided by the Archdiocese. It has 2 internal combustion engines of 1750 kilowatts each that turn electric generators to produce and deliver the power output to Commonwealth Edison (Com Ed). Sexton Energy LLC has a contract with Com Ed in which Com Ed takes all of the output from the facility. This Project’s energy is being sold to Com Ed for inclusion in the local distribution of electricity, without conveying to Com Ed any rights to the emissions reductions associated with capturing and destroying the LFG. Com Ed will purchase the power delivered to it during the life of the facility under the rates filed with the Illinois Commerce Commission (ICC).

Farmer-Owned Distributed Wind Turbines

NativeEnergy recently concluded a long-term agreement with Next Generation Power Systems, Inc., to support its sales and installations of German designed 40 kW Aeroman wind turbines that are remanufactured and customized for Midwest conditions. With up-front funding from NativeEnergy reducing turbine costs to an acceptable level, these turbines will help farmers reduce their long-term electricity costs, while helping stabilize the electricity grid with distributed, small scale power generation.
