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:

1. Technical aspects:
   
   1. Visit the locations
   2. Look for potential tie-ins for waste heat (example: boiler blowdown, steam traps, or flue gas connections that would not be used after the capture pilot projects have been closed).
   3. Look for potential uses for cooling (example: electrical or control rooms, heat rejection from rotating equipment, etc.)

1. Contractual aspects:
   
   1. Discuss potential PPA general terms (for the Demos FOA, this would be of great help to assess economics and justify commercial potential; ideally this meeting could be with PEI).

1. Sustainability aspects:
   
   1. Talk about how project integrates into iCAP (Pressure Corp wanted also to ask about potential benefits that the project may have on UIUC’s STARS rating).

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
