HCAI Releases New Guidance on Alternate On-Site Power Sources

What’s happening: The Department of Health Care Access and Information (HCAI) released new guidance on the use of on-site alternate sources of power other than diesel generator(s) to be used as the essential electrical system (EES) power source(s). 

What else to know: HCAI released a new code of application notice (CAN) on health care microgrids. The amendment in the 2022 California Electrical Code, effective July 1, is intended to permit the use of on-site alternate sources of power other than diesel generator(s) to be used as the EES power source(s).  

The amendment states that a health care microgrid, if used as an EES power source, shall be designed with “sufficient reliability.” However, the code does not define what constitutes sufficient reliability. The CAN provides the minimum standards required for the health care microgrid to be considered and provides direction on how to meet the on-site fuel storage requirements for health care microgrid sources other than diesel generators.  

The CAN and other guidance documents can be found on HCAI’s website.
