WESC - A data standard for water and energy supply and consumption.

Consumption information model

A fine-grained view of consumption based on readings for a single meter located on a property. For a single-dwelling there is a 1-to-1 mapping between the meter and the property ID, while for other property types there is a 1-to-many mapping between the meter and the property.

The general class MeterReading has the following specializations: WaterMeterReading, GasMeterReading, ElectricityMeterReading.

This view includes specific encodings for various types of readings, such as manual meter readings, indicated via the resultMethod (values selected from a controlled vocabulary).

Supply information model

A model for supply-related data. The general class UtilitySupplyData currently has specializations for WaterSupply, and for ElectricitySupply and ZoneSubstationElectricitySupply. These capture details of the supply region (local government area, jurisdiction, statistical area, etc), of the supplying utility, and the total amount of water or electricity supplied.

The time period can be indicated using a named interval taken from a pre-defined list (timeName) as an alternative to using an explicit startDeliveryTime and endDeliveryTime. Similarly, the supply region can be indicated using a named location or as a geometry such as multi-part polygons, single polygons or points.

GML SF-1 WESCML information model

The WESCML-SF1 model is a specialization of the Observations and Measurements standard (O&M) from Open Geospatial Consortium (OGC). O&M is a model and encoding for describing a wide range of observations from multiple domains. It is based on the Geography Markup Language standard. The actual time-series data is the result of an OM_TimeSeriesObservation which samples the reporting location at different times.

WESCML-SF1 has four main classes. WESC_MonitoringLocation describes the location of a supply or consumption monitoring process, which may be a point location, or an area such as a statistical or local government region from which an aggregation of meters is reported. WESC_MonitoringLocation also captures the monitoring type (e.g. individual meter, smart meter, or locality), the location name (e.g. street address, region, jurisdiction.) and reference description.

WESC_Commodity identifies the type of commodity (e.g. water, gas, electricity etc.) being reported, and its source (e.g. desalination, stormwater, surface water, groundwater; solar, wind, grid, etc.). WESC_Agent specifies the name and type of utility, organisation, individual, population, or environment supplying or consuming the commodity. The relationship between the WESC_Agent and WESC_Commodity indicates the role each plays (consumer, supplier). WESC_Procedure specifies the procedures used to determine or aggregate the observations, including the number of meters, the number of readings, and the statistical method used to generate the results.

Three code lists standardize the values for specific properties. These are:

• types of agents (e.g. residential, commercial, industrial, agricultural, municipal)
• commodity source (e.g. desalination, groundwater, hydroelectricity, coal fired power stations, etc.)
• statistical methods (e.g. average, interpolation, median, modelled)
