Designing Your Interval Register Types

Each register, which will record raw interval data will require an interval register type.

The essential attributes of an interval register type are the UOM/SQI, the minutes per interval and any validation algorithms.

For our examples, let's assume that raw interval data may be measured in kilowatts or megawatts and may be measured in either 30-minute intervals or 60-minute intervals.
For our examples, let's assume that the data may be standard recorded data or it may be calculated excess data. We will use an SQI to further label the excess demand.
For each register type in our example, we will use a validation algorithm, which will verify that the intervals are correct according to the interval size on the interval register type.

We will assume that all of our raw interval data will follow the same seasonal time shift as our base time zone. Refer to Time Zone and Time Changes and Designing Your Time Options for more information.


Interval Register Type	UOM/ SQI	Min/ Interval	Seasonal Time Shift	Validation Algorithm
KW60	KW	60	USShift	Validate interval size
KW60EXC	KW/EXCESS	60	USShift	Validate interval size
KW30	KW	30	USShift	Validate interval size
KW30EXC	KW/EXCESS	30	USShift	Validate interval size
MW60	MW	60	USShift	Validate interval size
MW60EXC	MW/EXCESS	60	USShift	Validate interval size
MW30	MW	30	USShift	Validate interval size
MW30EXC	MW/EXCESS	30	USShift	Validate interval size

We expect that you will need more algorithms than we supply. Your algorithms will be based on any number of factors. Be aware that new algorithms may require programming. See How To Add A New Algorithm for more information.
