Finning Power Systems has supplied
a combined heat and power (CHP)
solution for the various site processes
at Janssen Pharmaceuticals.

Due to increasing energy bills,
Janssen wanted a CHP solution
where electricity can be generated
directly on site. Heat produced as a
by-product can then be used to
produce steam and low temperature
hot water (LTHW) for its various site
processes.

Featuring a containerised
Caterpillar G3512E gas engine with
an electrical output of 1.0MWe, the
solution includes an exhaust gas
boiler producing up to 625kg/h of
steam and an LTHW recovery
system generating up to 569kWt. The
generator is designed to operate 24/7,
365 days a year, and is the prime
source of power for the facility.

The scope of the project included
supply and installation of a purposebuilt
boiler house, as well as a
transformer to step up power from
400V to 11kV. The installation was
designed to allow interfacing with
the site’s existing high voltage (HV)
ring infrastructure.

In addition to the CHP system
design, supply and installation,
Finning carried out commissioning
and testing, and will continue to
provide ongoing support.
