Settlement configuration entities: Markets, points, and zones

IEE settlement comprises three configuration entities: settlement markets, settlement zones, and settlement points.

Settlement Markets

A settlement market contains information about the market operator. Each market can be divided into zones within the market's territory. Utility providers and market participants are responsible for the settlement points within their zones.

A utility can have more than one market.

Settlement Zones

A settlement zone is a geographical area containing generators, interties, and/or substations. Multiple settlement points can be grouped into a zone, and multiple settlement zones can be grouped into a market.

Settlement Points

A settlement point is the main point of data storage for Official Load Value along with contributing data to provide the settlement data needed by the market. Settlement points are metering points that record usage throughout an market operator's geographical territory.

In IEE, a settlement point is represented by a service point configuration. Each service point has its own unique settlement point ID.

A settlement point is the main point of data storage for official load value, contributing data needed by the market. The settlement point also tracks the zone it belongs to. In the case of intertie settlement points, two actual settlement points are created, one designated as the receiver and one designated as the monitor (two because of the ID constraints and zone aggregation requirements). During configuration setup, the operators determine which of the settlement points is the responsible metering authority. One is set up as the addition of load in the zone, and the other subtracts from the other zone.

Some data is reported to the market based on zonal totals. Some data is generated at the market level, such as transmission line losses, and needs to be stored in IEE at a zone level and is viewable and accountable in the UI when viewing zone-level information.

The Settlement Market entity represents a real-world energy market. The market operator, i.e., ISO (Independent System Operator) or RTO (Regional Transmission Operator), manages the grid within their territory and regulates all participants within the market. This allows for dynamic aggregation of all related settlement zones, settlement points, data source contributors, etc.

Settlement points can be grouped into zones, and zones are grouped into markets. A settlement point can move in and out of zones. The same concept would apply to zones and markets.

• A market can have more than one zone and more than one settlement point.

• A zone belongs to a market and can have more than one settlement point.

• A settlement point can link to either a zone or a market, but not both.
