energibalanser

Energibalanser is a term used to describe the balance between energy production, imports, stock changes, and consumption within an energy system. The idea is to ensure that available energy matches demand over a given period, taking into account seasonal variation, weather, and market activity. The concept is used in both statistical reporting and real-time grid operation, and its interpretation can vary depending on the context.

In a statistical and policy context, energibalansen refers to the national or regional accounting of energy flows. It typically includes primary energy production, imports and exports, stock changes, and energy use by sector (households, industry, transport, services). Units are standardized to enable comparisons across fuels and over time. These balances are published by national statistical agencies or energy ministries and are used to assess energy security, efficiency, and policy outcomes.

In an operational or market context, energibalanser concerns the real-time balancing of electricity supply and demand. System operators monitor the grid frequency and forecast near-term demand, then dispatch power plants, activate reserves, and use storage or demand response to correct any deviations. Balancing markets, intra-day trading, and cross-border interconnections support this process. Imbalances can lead to charges or penalties for market participants and influence prices and reliability.

Cross-border cooperation and adequate storage and flexible generation are important for maintaining energibalansen, especially with increasing shares of intermittent renewables. The concept underpins planning, investment, and the design of energy markets and grid operation.
