# Benchmark Results
**Comparing the results of NEMED to AEMO CDEII Reporting for Regional Sent-Out Generation, Total Emissions and Average Emissions Intensity**<br>

This page contains all region data for `Sent-Out Generation`, `Total Emissions` and `Emissions Intensity` comparisons between CDEII and NEMED.
Overall the error is generally consistent with a few exceptions:
- A few instances in Tasmania for 2016, '17, '18 where Sent-Out generation is underestimated, with error impacting subsequent metrics.
- A short but quite low point (underestimation) in '18 for NSW1, QLD1, VIC1 in Total Emissions, also impacting Emissions Intensity.
- Substational issues with Victoria 2022 data for September-October which coincides with the market change from 30MS to 5MS.
These later two discrepencies are of enough significance that they are clearly visible in the aggregated NEM traces.
