overskuddsenergi

Overskuddsenergi, or surplus energy, is electricity production that exceeds immediate consumption in a given power system or market area. It commonly arises in grids with substantial intermittent renewable generation, such as wind and solar, when supply outpaces demand or when transmission capacity to export to other regions is limited. In such cases, the system experiences overskuddsenergi, which can pressure prices and grid operations.

Causes include high renewable output during periods of low demand, tight interconnection capacity, over-generation-related curtailment, or seasonal and diurnal patterns that reduce consumption. Also, rapid changes in weather can create short-lived surges in supply.

Handling overskuddsenergi involves exporting electricity to neighboring markets, storing energy for later use, or curtailing generation. Market prices may fall and occasionally become negative during oversupply, signaling the need to reduce production or increase exports. Grid operators and market participants coordinate through balancing mechanisms, day-ahead and intraday markets, and capacity planning.

Storage options include pumped hydro, batteries, and thermal energy storage, as well as converting surplus electricity into fuels such as hydrogen (power-to-gas) or synthetic methane. Demand-side measures, such as demand response, can also absorb excess energy. Long-term solutions emphasize grid expansion, more interconnections, and better market signals to align generation with demand.

In policy terms, overskuddsenergi highlights the importance of flexible resources, storage capacity, and cross-border cooperation to maintain reliability, minimize curtailment, and reduce emissions by making best use of renewable generation.
