Case study · Multi-campus hospital network
The largest healthcare network in New York State, with over 1,000 care facilities and 28 hospital campuses, turned to DaisyChain to solve a critical power-quality problem.

The problem
Several times a year, low-voltage alarms trip across Northwell's campuses and fire expensive back-up generators. As critical-care facilities, the hospitals run under an N+1 redundancy regime. Once a campus is on back-up power it is no longer at N+1, so it has to cancel or delay planned critical procedures.
Every event caused turmoil. Patient care was interrupted, procedures were postponed, and the network lost up to $1M per day per hospital. Northwell often had no idea what was triggering the alarms: something on site, or the utility failing to deliver power within its contracted voltage levels?
The solution
DaisyChain installed high-precision meters on critical loads across key campuses. The platform monitored and analyzed those loads in real time, giving a synchronized snapshot of every power-quality event.
The platform traced the voltage problems back to the utility and provided irrefutable evidence that the faults were not originated by Northwell's equipment. They came from bad quality energy on the grid. That let Northwell open data-driven discussions with the utility on improving delivery.
What comes next
A platform for the whole electrification pathway.
Peak shaving
Lower electricity costs as control functionality comes online across campuses.
Demand response
Access to utility DR programs for new operating revenue.
On-site generation
Solar and fuel cells, integrated and optimized for the highest value.
Battery storage
Batteries optimized across campuses for backup, peak shaving, and demand response.
Fleet electrification & EV charging
As Northwell electrifies its vehicle fleet and adds on-site charging, DaisyChain is engaged to integrate both onto the platform, so every new load is monitored and optimized alongside the rest.
Northwell and DaisyChain co-authored a white paper on unified power-quality intelligence for hospital campuses, available on request.
“Northwell Health has found DaisyChain to be among the most innovative and insightful of organizations. The breakthrough platform they are developing will provide the means to communicate with the grid in transition, while maximizing patient safety through enhanced hospital/utility intelligence.”
