Caltech Advanced Bloom Microgrid Implementation

This technical report outlines the implementation of the Advanced Bloom Microgrid at the California Institute of Technology (Caltech). The project began in 2009 with the installation of a 1 MW fuel cell capacity to provide clean and economical power through a Power Purchase Agreement (PPA). The initiative aimed to meet increased load demand, sustainability goals, and reduce utility costs. In 2021, an additional 1.2 MW was added to support the Chen Neuroscience Research Building, ensuring reliable power during grid outages. The microgrid operates with dedicated inverters that allow for simultaneous operation with the utility grid. The report details the sustainability metrics achieved, including a reduction of over 11 million pounds of CO2 emissions and significant water savings. It also highlights the benefits of partnering with Bloom Energy, which provides clean electricity at a lower cost and enhances reliability in Caltech's electricity distribution system. The document concludes with future considerations for transitioning to zero-carbon fuels.
