Plan Approval and Report
In December 2011, Stanford’s Board of Trustees gave concept approval to the $438 million Stanford Energy System Innovations (SESI) program, which is a collection of operationally distinct projects designed to meet the university’s energy demand while reducing greenhouse gas emissions and water consumption. SESI represents a significant transformation of the university from 100 percent fossil-fuel-based cogeneration to a more efficient electric heat recovery system. SESI will result in immense benefits for Stanford University in the years to come. When completed, the current set of projects anticipated under the SESI program will reduce campus greenhouse gas emissions by 50 percent, save 18 percent of campus potable water, open up the energy supply platform to future technologies, enable the campus to better manage its power portfolio, and yield utilities savings.
Analysis shows that the campus can recover up to 70 percent of the heat now discharged from the cooling system to meet at least 80 percent of simultaneous campus heating demands, significantly reducing fossil fuel and water use in the process. Based on this finding, Stanford will replace the current natural-gas powered cogeneration plant with an electricity powered Heat Recovery plant or the new Replacement Central Energy Facility.
