Grootvlei Power Station has an installed Continuous Emissions Monitoring System on the stack for monitoring particulate and gaseous emissions to comply with the National Environmental Management: Air Quality Act, 2004. Correlation of dust monitors means correlating monitor output against mass emissions (dynamic calibration). Parallel testing verifies online emissions with a certified parallel test monitor to produce a correlation factor. Eskom adopted VDI 2066 for dust correlation and EN 14181 for gaseous parallel testing. ISO 13284-1, ISO 9096, ISO 12141, and ISO 10155 are acceptable standards. Dust correlation frequency: once every 2 years (recommended 21-23 months); after full bag replacement, full correlation after 3,000 operating hours. Gas monitor parallel test frequency: once every 2 years (recommended 21-23 months); also required after major plant operation change, AMS failure, or spot check.

Contract duration: 5 years. Dust monitor correlation frequency: once every 2 years (recommended 21-23 months); after full bag replacement, full correlation after 3,000 operating hours. Gas monitor parallel test frequency: once every 2 years (recommended 21-23 months); also required after major plant operation change, AMS failure, or spot check. Contractor must submit plan for whole service within 2 weeks of contract date. Contract Quality Plan (CQP) due within 30 days of contract award; no work may commence until CQP approved in writing. Preliminary test report due within 5 days after testing. Completed full report due within 2 weeks. Late reports result in delayed payments and penalties.

Frequency: once every 2 years (recommended 21–23 months); spot checks as required; after full bag replacement, full correlation after 3,000 operating hours settling time.

Gas Monitor Parallel Testing: Eskom adopted EN 14181. Minimum 15 valid parallel measurements on normal operating conditions spread over at least 3 days, 8–10 hours per day, within 4 weeks. SRM measurements per accepted standard; AMS signal >90% averaging time. AMS and SRM as measurement pairs covering same time. Sampling time ≥30 minutes or ≥4× AMS response time (whichever greater). Results expressed under same conditions for calibration function and variability test. Additional correction parameters obtained per measurement pair. Frequency: once every 2 years (recommended 21–23 months); major plant operation change; AMS failure; spot checks as required.
