Among the sites where the CHP unit was designed to operate during a grid outage, all of the CHP systems did perform
as expected during Sandy. There was not a single site that lost grid power.

Challenges |
Project
Customer: Hospital de la Concepcion
Location: San German, Puerto Rico
Market: General & surgical, 167 beds
Average load: 1200kW
Purpose: Energy savings/resiliency
“We had good emergency preparedness plans that we put in place. We produce our own electricity on site. And also it
is more reliable since we don't have electrical lines, transmission lines or all of that losses that you have in a regular
system from the utility grid” - http://www.npr.org/2017/10/07/556320361/the-critical-needs-of-hospitals-in-puerto-rico
Key Lessons
Assess requirement for fuel flexibility
Help solve interconnect issues with island mode
Solution
Equipment: 2 x Jenbacher J420 (n+1)
