Certain types of Property Key have a large set of corresponding values and/or values that change frequently over time. Examples of these are property keys that hold wholesale energy price indexes that change hourly, or for monthly retail electricity fuel cost adjustment rates. In some cases, electricity rates can vary daily (New York) or even hourly (specialty variable rate plans). Whenever we need to track data that can have a large number of values, or values tied to a date range, or values that update at least monthly, we usually use a special type of Property Key that we call a "Lookup". These Property Keys include a lookup table to hold their values (hence the name). You can tell when a Property Key has a lookup table attached because itdataType field has a value of LOOKUP. The endpoints defined on this page allow you to query the values in their lookup tables directly in several useful ways. We also have an endpoint that summarizes the counts, averages, and durations of the lookup values.
Data Definitions
Lookup Value
A lookup value (resource type PropertyLookup) has the following data structure.
| Name | Type | Fields | Description |
|---|---|---|---|
| lookupId | Integer | M | The unique ID for this lookup value entry in the lookup table |
| K | String | M | The unique name for this property this lookup belongs to. |
| subPropertyKey | String | M | sub-property this lookup value applies to (when needed, e.g. wholesale index node or zone) |
| fromDateTime | DateTime | M | Date Range - from date time for this value |
| toDateTime | DateTime | M | Date Range - to date time for this value |
| bestValue | Decimal | M | Best kWh/kW price for the property key for the date range |
| bestAccuracy | Decimal | M | Reserved for future use |
| actualValue | Decimal | M | Actual kWh/kW price for the property key for the date range |
| lseForecastValue | Decimal | M | kWh/kW price forecasted by the utility for the property key for the date range |
| lseForecastAccuracy | Decimal | M | Reserved for future use |
| forecastValue | Decimal | M | kWh/kW price forecasted by Arcadia for the property key for the date range based on previous Values |
| forecastAccuracy | Decimal | M | Reserved for future use |
Get Property Lookup Values
