During testing we discovered that one of our generator circuit breakers operated intermittently and wouldn’t always close. This meant that when both of our backup generators were required to supply hospital demand, the hospital’s supply redundancy could have been compromised if the breaker didn’t close. Once the fault was identified, the ‘sticky’ breaker was replaced.
As we’re running our generators on load [in VPP participation], we can defer our weekly test for another week, because we've proven that we've met the required standard to test them on load.
This hospital is enhancing site resilience by participating in multiple DR programs in our VPP. The earnings are reinvested into improving its backup power infrastructure. Participation also protects the hospital's sensitive electronic equipment from deviations in the grid's frequency. Learn more.
