Construction of a new 54-acre, 12.32 megawatt (MWdc) Solar Farm has been approved by the University of Illinois Board of Trustees as the sole member of Prairieland Energy, Inc. Referred to as "Solar Farm 2.0," the new utility-scale array will be located north of Curtis Road, between First Street and Dunlap Avenue near Savoy. Solar Farm 2.0 will produce approximately 20,000 megawatt-hours per year (MWh/year), nearly tripling the university’s existing on-site renewable energy generation. Completion of this project will then grant the University of Illinois with the title of being the third-largest user of renewable power generated on-site for all higher education facilities in the entire country.

Project Inception

In April 2017, the Energy Sustainability Working Advisory Team (SWATeam) recommended that to increase our campus’ generation of solar power, either an extension should be built onto the original Solar Farm or additional solar panels be installed across campus rooftops. From there, the idea of Solar Farm 2.0 was born. In November of that same year, the Sustainability Council approved the concept of this new solar farm, and a site selection was completed during spring 2018. 

In the summer of 2018, after discussions with our neighbors in Savoy, the Chancellor’s Capital Review Committee approved the location, and a request for proposals was initiated. Different vendors from across the nation submitted proposals and various designs for this new solar farm, with nineteen submissions in total. By May of 2019, Sol Systems of Washington, D.C. was chosen to complete the project. A twenty-year contract was negotiated, and the overall project is on track to be completed by the end of 2020.

Project Overview

Sol Systems will be responsible for the design, construction, and maintenance for Solar Farm 2.0, and like Solar Farm 1.0, the Urbana campus will use all the generated power.  The $20.1M contract is anticipated to save the university $300,000 in the farm’s first year compared to electricity purchased from the wholesale MISO market. Prairieland Energy will buy the solar energy at a fixed rate of $45.99 per MWh, while the University of Illinois will receive the associated renewable energy certificates (RECs) and the right to claim the use of clean energy.

Pollinator Habitat

Other innovative features of Solar Farm 2.0 include the incorporation of a pollinator habitat located beneath the panels. Indigenous plants will be planted throughout the farm to welcome local and migratory birds and insects. Specifically targeted towards butterflies and bees, Solar Farm 2.0 will be a welcoming environment for wildlife, as well as being a demonstration site for meeting the requirements of the Pollinator Friendly Solar Site Act. A landscaped buffer will also be included in the final design of Solar Farm 2.0, creating visual screening of the solar panels along the south edge of the farm bordering Savoy.

The Solar Farm 2.0 developer will be planting the Solar Farm 2.0 site next week.  On May 7, 2021, they will spray an herbicide mixture to prepare the site.Here are the details they provided:

Glyphosate 41 herbicide and/or Ranger Pro.  They are both generic glyphosate-based herbicides. Ranger Pro includes a water-based surfactant in their formulation.    We will be adding a methylated seed oil for a surfactant.  We will not be using a spray dye in the mix to avoid residue on the panels.

When built, the University of Illinois Campus Instructional Facility (CIF) will be a four-story building dedicated to academic and classroom use. CIF will serve 31,000 students daily and will leverage sustainable design to decrease its carbon emissions. The ground source heat exchange system will consist of approximately 60 wells arrayed under the John Bardeen Quad. It will be designed to be expandable, with the ability to be connected to other buildings, allowing for multiple phases. This SSC grant covers approximately 13% of the cost of the geothermal system, and this building project is the first public-private partnership on campus. As the campus works towards being carbon neutral by 2050, this project will not only reduce UIUC’s reliance on fossil fuels, but pave the way for new construction projects to use geothermal systems on campus. 

The following is a message from John Marlin. In this message, Marlin includes information about the wildflower display at Lincoln Avenue Residence (LAR), as well as photographs of the location:

Hello,

At the moment and for the next several weeks woodland wildflowers will be blooming at LAR, specifically to the north of the front steps, continuing past the edge of the building, and alongside the north east side of the building.  There are about 20 woodland species in the mix.  This is a fairly good example of the type of plants that could be placed in small beds around campus to help pollinators and provide visual relief.  The spring plants are especially nice to have around as students face the stress of finals and leaving their friends for the summer. I believe you would find a visit worthwhile. I would be glad to join at any convenient time.

The project was initiated in 2016 by the LAR Living Learning Community.  In addition to the woodland plantings there are prairie and related plantings starting at the south side of the steps and continuing around the south side of the building to the loading dock.  An additional planting is in the courtyard by the dining room.  Various prairie species will bloom in sequence beginning now and through the fall.  These plantings compliment the nearby Red Oak Rain Garden.

Over 50 students and community members planted the area.  A part-time intern helped maintain it for the first year and a half.  A $5,000 grant paid for the most of the plants and intern.  There has been very limited maintenance due to the virus and lack of funds for the intern.  The main problems are some weeds and aggressive spread of some of the native plants.  Insects and birds use the plantings and several classes have visited.

There is a growing consensus in favor of locating pollinator pockets and other native planting around campus.  Once in the ground they require minimal maintenance.  A few seasonal student interns with some supervision could manage quite a few.  I hope there can be some action along these lines over the next few years.

The attached file shows the production of the new rooftop solar panels on BIF from June 2019 to March 2021. It also includes the approximate reduction in carbon emissions and the equivalent number of "trees saved."

The new 12.5 kW array will be the second rooftop installation at the facility. The current array, on top of Deloitte Auditorium, produces about 41,000 kilowatt-hours (kWh) annually, – or about 3.4% of the electricity needed to power BIF for an entire year. The new array will be smaller but will supply enough power to offset the anticipated energy usage of the fourth floor addition by contributing 15,500 kWh per year.
