ISO New England GADS Reporting Reminders

by ronfluegge 6. December 2012 11:19

In reviewing their monthly data submittals, the ISO New England noticed inconsistencies in reporting.  They ask that you please keep the following in mind when submitting your monthly data to PowerGADS:

1.       "OMC events will come in two forms: outages or deratings. The OMC event types can be either forced, maintenance or planned but it is expected that the majority will be forced outage events.”  Do not report OMC events as NC or RSFor more details see Appendix K of the NERC GADS Data Reporting Instructions

2.       "If you report both Service Hours and Gross Actual Generation (one to 9999999), GMC or GDC must also be reported. Similarly, if both service hours and a gross capacity value are reported, Gross Actual Generation must also be reported. This provides consistency when calculating performance statistics.”  Page IV-5 of the NERC GADS Data Reporting Instructions

3.       For every Startup Failure (SF) event you report, your Attempted Starts value increases by one. 

a.       Actual Unit Starts + Startup Failure Events = Attempted Unit Starts

b.      Additionally, if you have an unsuccessful start and report it as an attempted start, there needs to be a corresponding Startup Failure event.

4.       If you are getting the following warning “99-The Fuel Code specified in the Performance data is not defined as a primary, secondary or tertiary fuel in unit definition. The code is __”  Please verify that you are using the correct fuel code when submitting your Performance Data.
