REC Profile - Reinford Farm

The Dominion Green Power® program supports a number of renewable facilities within our regional power pool. The purchase of RECs from these facilities provides a vital income stream for furthering the development of renewable energy.

One of the facilities supported through the program is the Reinford Farms Livestock Biogas facility located in Mifflentown, Pennsylvania. The 900-acre Reinford Farm has been owned and operated by the Reinford family since 1993, carrying on the family’s long tradition of farming in the area.

During the winter of 2008 the family brought online a new livestock biogas system that uses methane released from the farm’s cow manure to generate renewable energy. The hard work involved in building and managing the livestock biogas system has paid off. The family sells the electricity and the Renewable Energy Certificates (RECs) it produces, and also uses the system to reduce costs and increase revenues in other ways.

Designed by RCM Digesters of Berkeley, California, the livestock biogas system moves manure produced by the farm’s 440 milking cows and 50 dry cows to a tank, where methane gas released by the manure is collected. This biogas is then piped to a 1200 rpm Caterpillar G342 engine coupled to a 250-volt AC, 60-hertz, single-phase 130 kW generator, where it is combusted to produce both electricity and heat.

On an average day the system generates 3,000 kWh of electricity, which is delivered straight to the power grid. In addition, the system produces heat that the Reinfords use for their home, milking parlor, and other buildings on the farm. The family also uses this heat to pasteurize raw milk that is fed to new-born calves - resulting in healthier young cows - and to dry corn that is raised at the farm for feed.

As an added benefit, the system produces sterilized solid waste that can serve as bedding for cows. The Reinfords use this bedding themselves and also sell to neighboring farmers. Switching to this bacteria-free bedding has led to an unforeseen benefit. Since the Reinford family began using it at their farm, bacteria levels in their milk have gone down 50 percent.

Drew Reinford, the family member responsible for building and managing the system, has some advice to other farmers who are considering installing livestock biogas systems. “Don’t expect to just sit back and let the system run after you install it. It is difficult for a livestock biogas system to pay for itself if you don’t find ways for it to generate revenues or savings outside of those from the electricity it produces.” He adds that he expects the system to pay for itself in five to six years.

As far as REC revenues, Drew says they make a real difference. “Economically, it can be difficult to run a small family farm. The steady monthly income that comes from the RECs helps us pay for upkeep and repairs to the biogas equipment and justify the time I and others spend managing the system.”

I find it a little unusual that Dominion's Green Power program can find no projects in Virginia to support. The funds, after all, are donated by Virginia ratepayers to support the growth of renewable energy in Virginia. Is it because no one here has any renewable energy projects?

The Dominion Green Power program does support renewable energy projects in Virginia. Our ability to support Virginia-based renewable energy has been somewhat limited in the past because of limited availability. However, we are happy that a recent boost of renewable energy projects has made it possible for us to incorporate more Virginia-based renewables in our program, including solar and biomass. We will continue to increase the amount of renewable energy supported in Virginia when feasible, while also supporting renewable energy from facilities located within our regional power pool. This diversity of renewable resources creates meaningful environmental benefits and helps ensure an affordable program for as many Virginians as possible.

That's Great! Would you mind giving a broad overview of the types and location of those projects? I can't find any references to those on the Dominion Energy Pages, even though the out of state projects are clearly identified. What recent boost are you referring to, and if someone is building a renewable energy project in Virginia, how should they go about selling REC's to the Green Power Program, to help finance it?

Thank you for your interest in the Dominion Green Power program. The 2011 Product Content Label on the Dominion Green Power webpage (http://www.dom.com/dominion-virginia-power/customer-service/energy-conservation/green-power.jsp) provides information regarding the renewable energy certificates (RECs) sourced for this program, including location and type of facility.

The Dominion Green Power program does not source any RECs from Dominion-owned facilities. Therefore, customers who enroll in this program are supporting renewable energy above and beyond Dominion’s renewable energy initiatives.

RECs are a mechanism that 1) allow people to support the growth of renewable energy production and claim the environmental benefits associated with their REC purchase; and 2) provide an additional revenue stream to renewable energy projects which helps make them more cost effective and in turn allows them to increase their production over time.

If you are developing a renewable energy project and are interested in selling your RECs to the Dominion Green Power program, email us with your facility and contact information at GreenPower@dom.com.
