ASGA May Teatime: Benefits and Realities of Solar Grazing, A Checklist for Shepherds and Solar Companies

How can shepherds and solar companies understand each other’s basic requirements and seal the deal?

Join us to hear about the updated “Solar Grazing Checklist for Shepherds and Solar Sites Mangers” from our friends in Vermont, who designed the checklist to help graziers and site operators understand each other’s positions. The conversation will be led by Alex DePillis from the Vermont Agency of Agriculture, Food and Markets and Kimberly Hagen, the Grazing Specialist at the Center for Sustainable Agriculture at UVM Extension. They’ll go over the checklist, provide examples, and talk about the challenges faced by both graziers and site operators.

Following their short presentation, the second half of the Teatime will be dedicated to a Q&A with solar site operators and shepherds, who will discuss best practices for grazing to manage vegetation in the Northeast.

Hosts: Kevin Richardson (ASGA) , ASGA Outreach Coordinator, and Stacie Peterson from the AgriSolar Clearing House and Energy Program Director at the National Center for Appropriate Technology .

About the Speakers:

Alex DePillis has been developing clean energy projects and policies in public service and in the private sector since 1993. In public service, he has developed renewable energy policies and programs and administered grant programs. At the Vermont Agency of Agriculture, Food and Markets, he helps farmers and solar developers develop agrivoltaic projects. He also has a regulatory role in Vermont’s statewide energy-siting process to review solar energy projects for their impact on farmland.

Kimberly Hagen is the Grazing Specialist at the Center for Sustainable Agriculture at UVM Extension. Kimberly joined the Center for Sustainable Agriculture in February 2012 to provide technical assistance and support for grass-based farms: for those already immersed in the practices, those planning to transition, and everything in between. Kimberly spent several years working on all kinds of farms around the world, finally returning to Vermont where she has been raising sheep, chickens, horses and the occasional cow, on her own grass-based farm since 1987, and providing agricultural education and outreach for NOFA to communities and schools.

Case Study: Solar Grazing at Susquehanna University

Some institutions of higher learning are reducing fossil fuel use by investing in solar panel installations on campus. However, most of them don’t use grazing sheep to manage the grassland under their panels. In 2019, Susquehanna University (SU) in Selinsgrove, Pennsylvania put into service a 14-acre, 3-megawatt solar system, located on its Center for Environmental Education and Research property. The school leases a flock of sheep from Owens Farm, located near the University in Sunbury, Pennsylvania, to act as natural lawn mowers for the fenced solar array.

This solar project is a partnership between the university and WGL Energy Systems. WGL owns and operates the facility under a 25-year power purchase agreement (PPA), and Susquehanna purchases electricity back from WGL. Commercial PPAs such as this allow organizations like SU to buy power directly from the generating company and not an electric utility. This arrangement gives the generation company an incentive to invest in renewable generation installations, which is a key part of financing projects like this. A second company, SCG Power, provided design and construction services to the project.

Caroline Owens of Owens Farm said that she dedicates 40 of her farm’s Katahdin sheep to fulfill the solar grazing contract with the university. Owens raises more than 100 sheep and works with the university to provide managed grazing under the panels throughout the pasture season each year. Owens is a member of the American Solar Grazing Association (ASGA), an organization promoting best practices for grazing livestock under solar panels. According to ASGA, solar grazing is one of the most common and effective ways to combine solar and agriculture, and sheep are among the best livestock choices for the task.

Though Owens Farm is paid by Susquehanna University for the grazing services provided, the arrangement is mutually beneficial: Owens Farm gets extra income and access to more grazing land, and the university gets well managed vegetation, which is essential for optimal performance of the solar array. Both Owens Farm and the university are happy for the opportunity to show a working example of their shared commitment to reducing fossil fuel use. The partnership has another benefit, too, in the form of a learning opportunity each year for a Susquehanna University student who gets to be a shepherd for a season and help manage the flock.
