AI summary
- Nova Scotia Power Incorporated submitted a final-cost work order (CI #28866, Project S265) for the installation of a Low NOx Combustion Firing System (LNCFS) on Trenton Unit 6, completed in 2008 as Year 3 of a four-year Environmental Compliance program to meet the 21,365-tonne annual NOx cap mandated under Schedule C of the Nova Scotia Air Quality Regulations (N.S. Reg. 28/2005).
- Total actual spending was $4,106,621 against a UARB-approved budget of $5,607,640, yielding a favourable variance of $1,501,019; the largest savings arose from materials ($937,597 under budget) and installation contracts ($471,162 under budget), both of which were estimated prior to procurement being completed.
- Scope included pre- and post-outage performance testing, installation of low NOx burners, overfire air system, windbox modifications, continuous emission monitors for NOx and CO, waterwall panel assemblies, and associated commissioning and staff training.
- The project was part of a system-wide program targeting seven solid-fuel generating units (Lingan 1–4, Point Tupper 2, Trenton 5 and 6); three prior LNCFS installations on Lingan Units 2, 3, and 4 had already been approved and completed, with NOx reductions confirmed consistent with forecasts.
- The filing includes the original September 2007 UARB approval sheet signed by VP Generation Planning & Infrastructure William Hattie, the 2010 final-cost approval sheet signed by VP Technical and Construction Mark Savory, and a detailed variance explanation by account.
