that must be replenished soon after a
severe weather event. In contrast, most
CHP systems operate on a 24/7 basis
and continued to operate during the
storm-related power outage event.
Furthermore, most CHP systems are
fueled by natural gas and natural gas
infrastructure is typically very resilient
and sees minimal disruptions during
power outage events.
If designed appropriately, during
a power outage event the system can
disconnect from the grid and continue

operations. This requires that the CHP
system have black-start capability and
have the appropriate switchgear controls
that allow it to operate in parallel with
the grid. The cost of installing this
equipment can vary considerably due to
site conditions5. However, by minimizing
the likelihood of a costly power outage,
including financial costs and health and
safety risks, the upfront cost will likely be
recovered during the first outage event.
Most recently, with Hurricane Harvey,
Irma and Maria, we saw CHP providing
significant resilience benefits. A prime
example in Puerto Rico is the 2 MW CHP
plant in Vega Baja. This plant operates at
the Matosantos food processing facility.
Although a good portion of the Puerto
Rico power grid is down, this site has
been operating on propane gas without
interruption since Hurricane Maria. The
plant has been operating since 2015 and
is in the process of building an anaerobic
digester to produce methane to fuel
the plant.
Another example of weathering the
storm is the University of Texas Medical
Branch (UTMB) in Galveston, Texas. UTMB

is a great example of a CHP system that
was built for resilience. After Hurricane
Ike in 2008, UTMB was shuttered due to
the significant damage from storm surge
and wind. There was much discussion
as to whether they should reopen the
hospital because of the risk of future
storms. Because the hospital is a level
one trauma center and is the only trauma
center on Galveston Island, the hospital
was rebuilt. To prepare for future storms,
the hospital took significant steps to
improve the facility's resilience. A key
component of this rebuild was the
installation of two 7.5 MW CHP plants,
located on opposite sides of the hospital
campus. These systems are placed 18
feet above ground level to protect from
future storm surge. The east CHP plant
is currently operational and the second
is undergoing commissioning. The
investment has paid off. During Hurricane
Harvey in 2017, the local utility lost two
feeders into the hospital due to a flooded
transformer vault. When the power
went out, the CHP system continued to
operate in island mode as anticipated6.
