Considering an Anaerobic Digester? Steps to Take and Contacts to Make (G-86)
However, an anaerobic digestion system requires a rather large financial investment as well as a large management responsibility. Anaerobic digesters are custom designed and built for your farm needs. They should be designed by an experienced designer who has already worked through the common problems associated with anaerobic digestion. Currently, biogas production is best suited for farms that handle large amounts of slurry manure with little or no bedding. A common rule of thumb for economical operation of an anaerobic digester is manure from a minimum of 200 dairy cows or an equivalent amount of swine or poultry manure.
1. Do your homework—read background information on biogas
- Anaerobic Digestion: Biogas Production and Odor Reduction From Manure—G77, fact sheet available from Penn State Agricultural and Biological Engineering Extension Office, 246 Ag Engineering Building, University Park, PA 16802, phone 814-865-7685.
- On-Farm Biogas production—NRAES-20 and Anaerobic Digesters for Dairy Farms—Extension Bulletin 458 are available from the Northeast Regional Agricultural Engineering Service, 154 Riley-Robb Hall, Cornell University, Ithaca, NY 14853, phone (607) 255-7654 or email firstname.lastname@example.org.

2. Seek preliminary technical assistance
Several organizations can help determine if anaerobic digestion is suitable and economically feasible for your farm.
AgSTAR is a federally-funded program to promote the economical use of anaerobic digestion systems to reduce farm methane emissions. AgSTAR provides digestion system vendor information, helps farmers identify loans and financing for biogas systems, and can analyze the economics of a farm biogas system. They can be reached by calling 1-800-95AgSTAR.
Natural Resource Conservation Service (NRCS)
Contact NRCS to perform an initial digestion system analysis for your operation. They should be able to estimate the size of a digester and engine generator as well as the expected costs and benefits of an anaerobic digestion system on your farm.
3. Talk to digester owners
Remember, however, that digester owners are busy people with businesses to run. Please be considerate of their time and be prepared with questions for your conversation.

4. Find out what safety equipment your electric company requires
Call to find out:
- Their Safety and Interconnection Requirements for Qualifying Facilities (the qualifying facility is basically your engine generator set) and their Policy for Cogeneration and Small Power Production.
- What price they will pay per kilowatt hour of electricity (their “buyback” rate).
- The cost for interconnection. This will depend upon your geographic location, distance from a transmission line, and the size of your generator. You should know the generator size before you call the utility.
Contact information for utilties and rural cooperatives
Be aware that the names may change—in most cases, you can call the main number and ask to speak with the Cogeneration Contact or the Engineering Department.

If you are experiencing difficulty in dealing with your local utility, call John Miller at the Pennsylvania Public Utility Commission at (717) 783-1546.
If your area is serviced by a rural electric cooperative, call your local cooperative or, for a listing of all the cooperatives, contact the Pennsylvania Rural Electric Assocation, 212 Locust Street, P.O. Box 1266, Harrisburg, PA 17108, phone (717) 233-5704.
5. Investigate potential financial incentives such as tax credits and loans
Currently, there are no tax breaks for biogas applications. Contact the IRS tax credit information service (phone 1-800-829-8815) or the Pennsylvania state biomass contact, Mike Palko, at (717) 787-2105, for up to date tax credit information.
Agricultural loan information can be obtained from Carl Mueller, Assistant Director of the Pennsylvania Department of Agriculture, Bureau of Economic Development, 2301 North Cameron Street, Harrisburg, PA 17110-9408, phone (717) 783-8460.
6. Talk to digester system designers and installers
Engineers will probably charge a fee for preliminary design work prior to construction. Therefore, you should be serious about installing a digester before contacting a designer. It is recommended that you choose a local designer who will oversee system construction and start-up and make changes if necessary. Inclusion in this list does not imply endorsement by Penn State Cooperative Extension.
