ppm = parts per million.
a Plant has a rated power of 100 MW; therefore, ±10% of the rated power is ±10 MW.
NOTE: Values in bold italic are computed based on the average of the values in the nearest 4 hours before and 4 hours after instrument
malfunction that were at a plant power level of ±10 MW of the power during instrument malfunction.
