The portion of global load served by MMGD: it is what separates global load from load net of MMGD.
Estimated: Value obtained by a statistical procedure, with uncertainty.
Why it matters
How it is measured
In MWavg integrated at the end of each half hour. In the published data, global load = load net of MMGD + load served by MMGD in all half hours checked.
Unit: MWavg, by half hour
Not to be confused with
Global load includes the portion served by distributed micro and mini generation; load net of MMGD is global load without that portion. In the published data, net load plus the MMGD portion gives the global load in all half hours checked.
What cannot be concluded
- It is not obtained by subtracting MMGD from the hourly load curve: the two products have different definitions.
