Update on the TransCanada’s Napanee Generating Station (NGS)

At a meeting with of the Community Liaison Committee on the 22nd Nov 2018 the following update was given regarding completion plans for the (NGS) and possible effect on the local community.


Construction of the physical plant is approximately 95% complete and the testing of over 130 individual operating systems is well under way. It is expected that the plant will be operating by the end of March 2019.


Employment levels during the construction phase were predicted to hit 750; they did in fact reach 1,500. The current employment level is 650 on day shift and 100 on night shift. TransCanada are anticipating that the total number of employees will be reduced to approximately 300 by the end of this year. Construction of the NGS has resulted in approximately $300M in local spending mostly in labour with some materials. (Local is defined as a 50 Klm radius.)

Steam Cleaning

Cleaning of steam transfer pipes and boilers will be commencing in December 2018 or January 2019. Pipes and boiler systems will be purged with high pressure steam to remove rust and debris which may have accumulated during the build process.

Cleaning will take somewhere between 7 and 17 days. This will be a continuous 24 hours a day 7 days a week process which will see high pressure steam vented to the atmosphere causing a large visible plume. Temporary silencers will be installed at the outlet vents in order to reduce the noise to an acceptable level. The silencers are designed to attenuate noise levels from 150dba to approximately 85dba.

Restoration of land

After the plant commissioning TransCanada will begin to complete the site paving and roads. This will be followed with the decommissioning of the construction site and restoration of the area to agricultural land. Over the summer of 2019 it is anticipated that there will be between 5,000 and 10,000 dump truck loads of material removed from the site.  The final destination and route used to transport this material has not been decided.
