General FAQ

Will the Focus on Energy incentives be distributed as a reimbursement following successful installation of the project or will the funds be available to assist with the purchase of equipment and construction of the facility?

From page 7 of the RFP: “Applicants will receive the full incentive award upon completion and verification of the system by Focus on Energy personnel, with standard processing and review times applied. Focus on Energy incentives serve as a reimbursement for verified installation and operation of the energy-related aspects of a proposal.”

Will the Seminar on February 1st also be hosted at remote locations around Wisconsin?

No. The Seminar will be recorded and made available for viewing after the 1st of February. It will not be available for viewing live at the time of the event.

Will the Seminar on February 1st be available for viewing online?

Yes! The Seminar will be recorded and made available for viewing after the 1st of February. It will not be available for viewing live at the time of the event.

Is there a specific number of digesters a proposal must include in order to qualify for evaluation?

No. The number and geographic orientation of digester systems is not prescribed in the RFP. While the configuration of the digester(s) is left to the discretion of the applicants, please note that the proposed configuration must also address the other primary criteria of the RFP, including water treatment and recovery and nutrient management improvements.

Will there be a list made available to potential applicants of other entities interested in forming an applicable consortium?

Yes! Through voluntary contact information collection with registration for the Seminar on February 1st, a list of interested parties will be made available and posted on the RFP webpage.

Can an aerobic digester technology be submitted as part of an eligible proposal?

Since aerobic digestion does not produce biogas or other marketable energy products, a proposal containing aerobic digestion would be insufficient to meet the energy-related evaluation criteria found on page 14 of the RFP.

Will the PSC accept and respond to questions submitted by Applicants after the pre-proposal seminar (Feb 1, 2017) and before Proposal Due Date (May 1, 2017)?

Yes! All questions can be submitted until the proposal deadline on May 1, 2017 and we will respond to them as quickly as possible.

Will increasingly larger farms benefit disproportionately from the proposal?

Not necessarily. The combined volume of manure from all participating farms will need to be large enough to support the system. However, that volume could come from many farm operations. Additionally, the RFP requires at least one participating farm have less than 700 animal units.

What additional public dollars will be required to implement this project?

There is no requirement for additional public funds to be applied for and secured as a condition for funding through this RFP. This program is designed to encourage private investment. Additionally, other funding options are highlighted in the RFP to cover costs of water treatment starting on page 5.

Will the proposed system reduce pathogens?

Anaerobic digestion and water treatment technologies can effectively reduce pathogen levels in manure, enabling application of manure nutrients with a reduced risk of public health impacts. Will this system reduce pathogen levels in my manure? To what extent? Does the company have data on actual pathogen reductions as a result from this system?

Will the proposed system reduce bedding costs through manure fiber utilization?

Solids within the manure are often separated out after the anaerobic digestion process is complete. Separated solids can then be dried and used as bedding for livestock.

Additional considerations: Will I be able to utilize the bedding product from the digester on my farm? Would this reduce my bedding costs? If so, by how much?

Will the proposed system reduce odor?

Many anaerobic digestion systems are able to reduce the emissions of noxious gases from raw manure.

Additional considerations: How much odor can be reduced through this system? Is there an economic or public relations value for me for odor reduction?

Will the proposed system increase nutrient availability?

Post-digested manure and additional effluent treatment can create multiple waste streams.  Some post-digestion products could come in the form of higher concentration nutrient products, low-nutrient content “tea water” and extremely clean dischargeable water.

Additional considerations: What post-digestion nutrient products would be most useful to me on my farm? What is the benefit of more readily available nutrients for crop uptake? Will this system produce effluent types that result in more efficient use of my nutrients for my farm? Will this reduce my commercial fertilizer costs?

Will the proposed system provide weed kill?

The digestion process can reduce the survival rate of weed seeds that are contained in livestock manure.

Additional considerations: To what extent can this system provide weed control? What effect could that have on my crop yields?

Will the proposed system reduce greenhouse gas emissions?

Capturing and utilizing the methane that is created by the anaerobic digestion process ensures that methane isn’t being emitted to the atmosphere. Methane is a powerful greenhouse gas and markets exist that will compensate digester operators for capturing that greenhouse gas.

Additional considerations: Will this system allow for the sale of carbon credits or market renewable energy credits? Will I receive a portion of the revenue?

Will the proposed system generate tipping fees from co-digestion?

Food processing or wastewater treatment facilities may be interested in having their wastewater processed through this digester system rather than have the responsibility to treat their wastewater on their own. Often digester owners are paid to take wastewater from these types facilities.

Additional considerations: Will this system utilize co-digestion to increase biogas generation potential? What, if any, tipping fees will this generate? Will I receive a portion of the tipping fees?

Will the proposed system create revenue streams for potential value-added products?

Value-added products are often a component of digester systems to help increase the economic value of the project. Value-added products could include saleable fertilizer products, livestock bedding, compost, etc.

Additional considerations: Will this project result in the development and resale of value-added products? How will the income generated from the sale value-added products be distributed?

Will the proposed system require personnel to manage the digester?

Digester systems require a significant amount of time and expertise by its operators to ensure it is functioning efficiently and continuously.

Additional considerations: Will this system include hiring/identifying a professional manager to operate and maintain it? If so, at what cost? If not, who will be responsible for operating and maintaining this system?

Will the proposed system require new manure storage?

Because multiple waste streams may be generated through this system, participating farms may need additional storage options to contain and handle the different nutrient sources each farm receives back from the digestion system.

Additional considerations: Will participating in this system require me to add additional manure storage on my farm? How much will it cost to purchase any necessary manure storage required by this system? Can the costs to install new storage structures be offset by grant or cost-share programs?

Will the proposed system increase equipment costs?

The nutrient sources farms may choose to get back from the digestion system may require new ways of handling and applying those nutrient products.

Additional considerations: What new equipment (i.e. spreading or irrigation equipment) will this system require me to purchase to fully utilize these new nutrient products?
