As prime consultant and lead engineer for the Stanford Energy System Innovations (SESI) project, AEI designed and directed implementation of new central components projected to be 70% more efficient than the prior cogeneration and steam distribution process, reducing Stanford's carbon emissions by 75% and potable water use by 60%. AEI worked with Stanford to analyze energy production options, evaluate capital and operating costs, and assess financial and energy risk through 2050.
The Stanford Energy Center, designed for a peak load of 28,000 tons of cooling and 350 mmbtu/hr heating, replaces a combined heat and power system with heat recovery chillers that - along with standard chillers and gas-fired hot water generators - capitalize on daily heating and cooling overlap to heat the campus, and hospital with recovered energy. Two million gallons of hot water and ten million gallons of chilled water Thermal Energy Storage accommodate high demand periods. Portions of the facility are regulated by OSHPD. A new 80 MVA, N+1, 60kV-12.47 substation will allow flexible future management of Stanford's energy supply platform. Conversion of nearly 200 campus buildings from steam to hot water includes district energy heat exchanger stations at each building and over 20 miles of a direct buried, highly insulated, low loss hot water piping system conforming to European Standard EN253. SESI became operational in 2015.
