> By creating ice when electrical rates are low and then “burning” it during the hottest part of the day, the Ice Plant saves Stanford roughly $500,000 per year and decreases Stanford’s peak electrical demand by 8 megawatts.
That's 8 MW ... you say 22 MW today, but in 1999 that 8 MW offset looks more like Solar Two ( https://www.nrel.gov/docs/legosti/fy97/22835.pdf ) which produced 10 MW and cost 58 million on 126 acres of space.
> In 2015, as part of the Stanford Energy Systems Innovations (SESI) program, a new Central Energy Facility (CEF) was built, and the cogeneration plant and ice plant were retired. SESI transformed the university energy supply from a 100% fossil-fuel-based combined heat and power plant to grid-sourced electricity and a more efficient electric heat recovery system, helping Stanford achieve 100% renewable electricity.
The purpose isn't to add to the solar capacity but rather offset the power needed to cool the campus.

And yes, it has changed since then.
