Hi Rob and Tony,

Tim Mies asked me who “owns” the RECs from small scale solar arrays at individual buildings.  I said I’d have to check into it.

At first I thought all RECs are owned by central campus (UES), but then I questioned myself.  For a rooftop solar array, we don’t include it in the M-RETS program, and at ECE, we only “sold” them the solar farm 2.0 RECs.  We let them count their rooftop solar directly and they have the DOR accordingly. 

So is it appropriate to tell him that the RECs associated with the 14.7 kW array he is planning to install at the Energy Farm (not the SCAPES project) will be considered “used” at the Energy Farm?

I would caution that we do not want individual departments to get into selling RECs, without a much broader discussion.  So perhaps we should say that he can use/retire them at his site, but he cannot sell them without further discussion?

What do you recommend?

Thanks,

Morgan

Good questions. I think that if the department “owns” the REC, then they should also be able to sell the REC. I am interested in others views on the topic, and agree that it would lend to a much broader discussion.

I agree that a broader discussion would be helpful.

Best,

F&S completed the renewal of our recognition as a Green Power Partner through the US Environmental Protection Agency. Green Power Partners of our scale now have to use renewable power for seven percent of their annual consumption. Fortunately, the FY21 green power supply for FY21 was 9%, which is a +1.72% increase from the FY19 supply of 7.28%. See attached file.

Overview submitted: 

The University of Illinois Urbana-Champaign (UIUC) is proud of its sustainability initiatives and success in achieving Illinois Climate Action Plan (iCAP) goals (https://icap.sustainability.illinois.edu/). The iCAP is the university’s strategic plan to meet the Climate Leadership Commitments, including being carbon neutral as soon as possible and building resilience to climate change in the local community.

The Urbana campus on-site renewable energy portfolio meets more than 12 percent of annual electricity needs (https://fs.illinois.edu/services/utilities-energy/production/renewable-e...). UIUC’s Solar Farm 2.0 was energized in January 2021, producing 20,000 MWh/year. Combined with Solar Farm 1.0 and other rooftop and ground-mounted solar installations, the Urbana campus generates more than 27,000 MWh/year, ranking UIUC third amongst U.S. universities in on-site clean power production. Incorporating renewable energy continues to be a focus of new facility construction and major renovation projects. Most notably, the innovative Electrical and Computer Engineering (ECE) Building features 970 rooftop panels. Since production started in April 2019, 11 percent of all power supplied to the ECE Building has been from the array, while additional output is reserved for research and educational activities. In September 2016, the university also signed a ten-year wind power purchase agreement for 25 million kWh/year and the rights to the environmental attributes.

The new ECE building is designed to include Solar Panels on its roof. The panels will provide about 11% of the building's energy needs.  The infrastructure for connecting these panels to the building electric supply was included in the original design and construction costs for the full building, while the solar panels themselves were funded separately. This specific project is to have a series of photovoltaic solar arrays on the roof of the building with a 300 kW peak power rating, capable of generating an estimated 470 MWh of electricity annually. (This project is distinct and separate from the project to install solar panels on the roof of the North Campus Parking Deck.) The scope of the project is to provide a structure located on the existing roof of the ECE Building which will support 950 solar panels and provide all components to connect them to the building electrical system for a fully operational system

I am on the team that did the Retrocommissioning project in 2018 and I would be happy to share some of our knowledge from that process.  Below is the link to a presentation of that project that we took to a Big Ten energy conference.   Some of our main takeaways are that the combination of chilled beams, dual HX wheels, coil sizing, occupancy ventilation, and thoughtful building pressurization have led to one of the most efficient buildings on campus.  Also, the heat pumps work well to heat/cool with electricity, but would be optimal if there were more of a reheat load, or a hot water loop to send reject heat to a neighboring building in summer, which campus is looking into in certain locations.

Joyce Mast is coordinating a Request for Purchase to buy and install the solar panels that will go on top of the ECE Building.  The building already has the structural supports for the panels, so the purchase will include the racks, PV panels, and inverters.  Joyce is working with ECE's administrative office, the Purchasing Department, and F&S Capital Programs to facilitate this RFP.
