Energiasijoitusjärjestys

Energiasijoitusjärjestys, or energy investment priority order, refers to the established sequence in which different energy sources are utilized or prioritized within an electricity grid. This order is typically determined by a combination of economic, environmental, and technical factors.

The fundamental principle behind the energiasijoitusjärjestys is the dispatch of electricity generation units. In most markets, power plants are ranked based on their marginal cost of production. The cheapest sources, such as renewable energy like wind and solar power, are usually dispatched first as they have very low or zero marginal operating costs. Following these are often lower-cost fossil fuel plants, such as natural gas combined cycle plants. More expensive options, like older coal-fired power plants or peaker plants that are brought online only during periods of high demand, are typically dispatched last.

This order ensures that electricity is generated as affordably as possible for consumers. It also plays a crucial role in grid stability and reliability. By prioritizing predictable and readily available sources, grid operators can manage supply and demand effectively. Environmental considerations are increasingly influencing this order, with policies often favoring cleaner energy sources to reduce carbon emissions and other pollutants. The specific energiasijoitusjärjestys can vary significantly between different countries and regions due to differences in natural resources, energy infrastructure, market regulations, and environmental policies.
