Daily diagram

A daily profile is a graphical representation of the projected or actual electricity consumption and production throughout a single day, often divided into hourly or quarter-hourly intervals. This profile provides a detailed overview of how electricity consumption and production fluctuate over the course of the day, enabling effective planning and management of energy resources.

Delivery point

The consumption point is a location where the end consumer purchases electricity for their own use. This could be a household or a business. This location is usually the same as the place where electricity consumption is measured. The consumption of one consumer can be measured at multiple consumption points, allowing for accurate monitoring and management of electricity usage.

Deviation of the delivery point

Deviation of the delivery point is the difference between the planned daily diagram of electricity consumption and the actual electricity consumption at a specific delivery point. The daily diagram is prepared for each delivery point a day in advance and is sent to the balance entity, often the electricity supplier. The sum of all deviations for delivery points under a single balancing entity constitutes the total deviation for that balancing entity.

Deviations of the delivery points are crucial for effective management of energy flows and ensuring the stability of the electricity grid. Accurate planning and monitoring of these deviations help minimize financial losses and enhance the reliability of electricity supply.

Deviation of the settlement entity

Deviation of the settlement entity is the difference between the planned and actual delivery or consumption of electricity reported by a specific settlement entity in the electricity grid. This deviation occurs when the actual values of electricity consumption or production differ from the planned values and can be either positive (surplus) or negative (deficit).

Diagram of electricity consumption

Data on the delivery point’s electricity consumption. Electricity usage is recorded in 15-minute intervals. This data is provided to customers by the electricity supplier upon request. In some cases, customers can access the diagram of electricity consumption online, on their energy supplier's website.

Distribution system

The distribution system is a part of the electrical grid that ensures the delivery of electrical energy from the transmission system to end consumers such as households, businesses, and public institutions. The distribution system operates at lower voltages compared to the transmission system and is designed to efficiently and reliably provide electrical energy at a local level.

Distribution system operator

A distribution system operator (DSO) is an entity responsible for the operation, maintenance, and development of the electrical distribution network within a specified area. It ensures the reliable distribution of electrical energy to end consumers.

The role of a distribution system operator includes connecting new delivery points, handling failures and implementing technical or legislative requirements.
