What We Do



• organize, own, and operate community

anaerobic digesters.



• work with proven technology partners



• fund with local equity, bank loans, and

government grants



• process dairy manure to greatly reduce

odor and bacteria while blending with

nutrients from food waste

Farm Power Rexville

750kW—two farms—1500 cows

Mount Vernon, WA

Operating since August 2009

Farm Power



Farm Power Lynden

750kW plus greenhouse heat—2000 cows

Lynden, WA

Online since December 2010



Where We Are Going



• more multi-farm projects



• expanding in Washington and

down into Oregon



• advanced nutrient recovery

Farm Power







Partners Helping Us Get There



• great support from the State of

Washington and county governments



• farmers, utility, and bank all came

together for successful projects

Farm Power









Revenues



• Electricity provides at

least 50% of revenue

under long-term contract



• Need revenues from

other sources to make

project financially viable

Farm Power





Flow Example--Farm Power Lynden

Electricity to PSE

Remaining half of surplus heat to greenhouse

80% thermal

efficiency

Farm Power







Greenhouse Heating



• hot water radiant floor is

highly efficient



• further gains if hot water

storage or top heat is installed



• supply not always matched to

need but covers 50% annually

Farm Power







Rules for Permit-exempt Co-digestion



• Livestock manure (>50%)

• Organic waste (<30%)

o Pre-consumer

o Animal parts source-separated

by licensed food processor

o No “Specified Risk Material”

o No sheep waste

o No municipal/residential solid

waste

o No bio-solids

Hydroelectric

Average plant size:

scale energy, even the

largest biogas projects

barely get noticed

Building Successful Projects



• utility standard offer fixed for

ten years, but even green power

worth under $0.10/kWh



• loan guarantees to secure bank

lending



• customized carbon offset

contract to differentiate

community design

Farm Power







Opportunity after 2012



• economics may be worse--with

limited value of carbon offsets

and green power



• projects built today allow

learning--to support innovation

required to survive in future
