INVISTA – Kingston installed a Combined Heat and Power (CHP) plant to displace a portion of the load normally supplied from the grid. Stream is used for process and space heating.

INVISTA – Kingston CHP output is 7.9 MW of electricity and 35,00 lbs/hr of 250 psig steam. The plant realized annual electricity savings of up to 50 GWh. INVISTA received $5.8 million in incentives through Hydro One’s Process & Systems Upgrade Program which helped provide a project payback of 4 years. Most of the steam generated by the CHP system is blended with steam from plant boilers and supplies heat to the plant. This type of facility is known as behind-the-meter since it reduces the net incoming power from the grid without exports of power.

INVISTA engaged CGTA to study the implications of installing a cogeneration plant at the Kingston Site. CGTA provided the front end Studies, specifications, detailed design engineering (mechanical, electrical, instrumentation, control, civil and structural) for the design of the CHP and commissioning support.

As INVISTA is a Class A Hydro One customer their most significant savings have come from the reduction in peak demand. The new plant offers additional energy savings due to increased efficiencies that are helping INVISTA meet a key corporate goal of reducing energy intensity by 20% before 2020.
