Microgrids for Healthcare Facilities

Climate change and the penetration of renewables present both a number of challenges and opportunities for hospitals in California. Both planned and unplanned power interruptions are currently managed through the use of diesel generators, which in turn create emissions that contribute to the climate crisis. These critical healthcare facilities need a reliable and sustainable power distribution system in order to properly care for patients. Hospital microgrids are an ideal solution.

This white paper, from the Hospital Building Safety Board – Energy Conservation and Management Committee, explores how California healthcare facilities can use microgrids to address the challenges of climate change and better utilize renewable energy resources. The paper first outlines the characteristics of a microgrid, its energy sources, and microgrid control systems. Then, the authors look at operations and maintenance as well as the role solar and other renewable energy resources play in a microgrid.

The white paper explains how energy storage technology like battery energy storage systems and fuel cells work with a microgrid. The authors also cover relevant codes and regulations that healthcare facilities should be aware of when considering a microgrid.
