Finning Supplies CHP Solution to Janssen Pharmaceuticals

Part of the Johnson and Johnson group of companies, Janssen Pharmaceuticals develops and markets innovative, high-quality pharmaceutical products and services aimed at improving quality of life for people with medical needs across the world.

Due to increasing energy bills, Janssen specified a combined heat and power (CHP) solution where electricity can be generated directly on site. The 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 1.0 MWe, the CHP solution supplied by Finning includes an exhaust gas boiler producing up to 625kg/hr of steam and an LTHW recovery system generating up to 569kWt. 

The generator is designed to operate 24 hours a day, 365 days a year and is the prime source of power for the facility.

The scope of the project also included the supply and installation of a purpose built 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 full commissioning and testing before completion of the project. As part of the project, Finning will continue to provide ongoing support including servicing, genuine spare parts and remote monitoring.  

Commenting on the success of the project, Colm O'Donovan, Chemical Production Engineer at Janssen Pharmaceutical (IRE) said: “We are continually seeking ways to improve our environmental performance and this move to on site generation of power is a key element in our strategy for carbon reduction. The increased efficiency will also significantly reduce our ongoing utility costs.  

“By partnering with Finning Power Systems in this project we have benefited from a total service solution, which began with the initial system design and will continue through the long term care of the system.”
