A representative from the News-Gazette reached out to Steve Breitwieser with questions regarding Abbot Power Plant:
Please also see the attached spreadsheet with data on steam supplied buildings.
Hi Kathy,
Abbott Power Plant generates all district heating and almost 275,000
megawatt-hours (MWh) of electricity each year using a high-efficiency
cogeneration process, which simultaneously produces both steam and
electricity. When the campus load for heat is highest during the
winter months, the plant, along with the two utility-scale solar
farms, provides almost all the electricity that the campus needs,
with the remainder coming from wind energy that is imported onto the
campus grid. Throughout the year, Abbott's sustainable cogeneration
process supplies approximately
85 percent of the total energy demand (steam and electricity) for the
Urbana campus, which includes almost 50 percent of the overall electricity usage. The electricity not generated at Abbott, from
on-site solar arrays, or acquired through a wind power purchase
agreement is purchased through Prairieland Energy, a corporation
solely owned by the University of Illinois Board of Trustees. More
information about utilities production is available at https://fs.illinois.edu/services/utilities-energy/production.
Happy Holidays!

Hi, Steve. As I'm assembling this week's column, I have several
follow-up
questions:
Can you clarify what's meant by "district heating"?
Does most of the steam generated by the cogeneration process end up
heating some of the older buildings on campus? (I spent 20+ years in
Mumford Hall and remember the sounds the pipes made at certain times of year.)
Any idea of approximately what percentage of the campus' interior spaces are still heated with ssssssteam heat?
I took a look at the website you mentioned, and have a couple of questions
about that: What does UES stand for? And the website says, "During low
campus demand for both heat and air conditioning, Abbott typically
burns natural gas. During the winter months, when the campus heat load
is highest, a combination of both coal and natural gas is necessary."
Is that information still accurate? (I thought the coal scrubbers were
no longer in use on campus...?)
If it's not possible to get answers to me this week, that's OK; I can hold the item for next week.
Thank you,
KR

Hi Kathy,
I'll follow up on these in greater detail when everyone returns next week.
UES is the acronym for the Utilities & Energy Services division that is within Facilities & Services. District heating is referencing the process used to distribute steam from Abbott to campus facilities through underground pipes.

Mike/Dave,
There were a couple of follow of questions to this media inquiry from the NG before the break. Can you help clarify the highlighted sections by Wednesday with any additional information? For the interior spaces question, let me know if you can explain that more precisely – on our website we say “More than 250 campus buildings use the steam produced at Abbott for their heating.” The UMP also indicates: From discussions with U of I staff, approximately 85% of the campus condensate is returned to APP (if that would be something to note from a process standpoint along with an explanation like below).
Abbott uses gas turbines, natural gas-fired boilers, and coal fired boilers, recovering reject heat from electric generation to help produce steam. The plant pipes steam underground across campus to provide buildings with space heating, domestic hot water, sterilization, and more. Once used, the steam condenses into water and returns to the plant where it is recycled and reused.
I could respond to the fuel item with what we have said previously…
When the campus load for heat is highest during the winter months, natural gas and coal are utilized to meet the significant energy demand. The coal-fired
boilers are also a part of research efforts, primarily related to carbon capture technology. Additionally, maintaining fuel flexibility provides the university operational reliability and the ability to respond to market factors for purchased utilities.
Thanks for helping out with some more detail on this one.

Mark/Dave,
Do you guys or maybe steam distribution know approximately what percentage of campus buildings are still on steam heat?
Thanks
David Hardin
------------------------------
I have not seen a list. We will ask Steam.
When time allows maybe we could add a column to note the steam yes or no. Hmmmmm Elizabeth stated Keith Erickson had a list and she recalls some sort of building database that listed utilities per building such as steam, electricity from Abbot or Ameren, gas etc. It would be nice to find this.
Dave
---------------------------------
Mike/Frank,
Are you guys aware of the list/database Dave referenced below and if so where it is located?
Thanks
--------------------------------
David,
I would think that EBS would provide a list of building that are served with steam, based on the meters in EBS.
Tony and/or Kate,
Can you clarify/confirm how many buildings on campus are served with steam from EBS? The email string below indicates that the Util. Master Plant said over 250 buildings are served by steam from Abbott. Is that still the case?
Mike Larson
------------------------------
According to EBS, there are 175 active steam meters. Some buildings have multiple meters so there would be fewer buildings than that.
Thanks,
Kate Brewster
------------------------
Anthony should be able to run a query that will give us an exact number from our last billing cycle.
Regards,
Tony
-----------------------------
As of our last EBS billing the count is 147. I have attached the file that supports this number for your reference.
Regards,
Tony

Below is an email from Sebestiano Geirdinella:
Hi Rob, Mike, Morgan,
I know that winter has just arrived so you must be having your hands full, but I wanted to contact you as there is now a DOE call for proposals for Long Duration Energy Storage Demos.
The Demo favors teams composed of industry / commercial partners with academic institutions. Pressure Corp has manifested their continued willingness to serve as commercial / industrial partner.
If our proposal is successful, it would allow us to consider other aspects to the project that would otherwise be too expensive to include into commercial contract without partial federal funding, such as: a) waste heat recovery from Abbott Power Plant, b) an alternate arrangement that includes providing cooling using the expander colder gas exhaust during summer, and c) including the expander at Curtis Road pressure regulation station (it could cover the roughly 3000 ft of electrical interconnection).
As part of the proposal preparation process, we feel it might have value to organize a visit to Abbott Power Plant with Pressure Corp, with the purpose of discussing technical, contractual and sustainability aspects relevant to the Compressed Natural Gas Energy Storage demonstration project:
It would be ideal to schedule the visit within the next couple of weeks, since we need to submit a Letter of Intent for DOE by the second week of December, but we are subject to your availability.
Please let us know if you have preferred dates.
Thanks and regards,
SEBASTIANO GIARDINELLA
This webinar will discuss a series of proposed & finalized amendments to rules promulgated by the US EPA to the Coal Combustion Residuals Resource Conservation and Recovery Act Rule. This presentation will summarize the analysis from EPA’s Composite Model for Leachate Migration with Transformation Products and contextualize that output with the USWAG Decision and the 2020 Rulemaking efforts.

The Energy SWATeam's early October meeting involved discussions on the draft 2020 iCAP Objectives created by the SWATeam members.
Beginning on June 1, 2012 the University quit burning coal as the campus energy needs declined with the beginning of summer. The University had gone without coal for 20 weeks in the summer of 2011. Abbott Power Plant began burning coal again on September 5, 2012 after 14 weeks without burning.
As of June 1, 2012, the University will again try to meet campus energy without burning coal in the summer months.
F&S and the Beyond Coal student group portion of Students for Environmental ConcernS (SECS) held a joint celebration at Abbott Power Plant to recognize the efforts that have been made to reduce coal usage for campus. There was a discussion about the additional projects F&S is pursuing and the financial decision makers for campus.
The F&S Energy and Production Distribution Master Plan was kicked off in January. This plan is the first step to achieving the goal of not burning coal at Abbott Power Plant by 2017. The plan will be developed over the course of calendar year 2012 and will include specific projects and cost estimates for implementing the plan in five-year increments.
Abbott Power Plant began burning coal again on August 30, 2011 after they stopped on April 12, 2011. The power plant went 20 weeks without coal, but needed to start burning it again as needed to meet the energy demands on campus as students began to return for the Fall 2011 semester.
Beginning April 12, 2011 Abbott Power Plant will no longer burn any coal during the summer, when natural gas is enough to meet the campus energy demands.
In May 2010, the News-Gazette published the article "UI promises to stop coal use by 2017, take other steps to lower energy use".
The attached file shows questions and answers about the energy on campus.
