energiasijoitusjärjestyksessä

Energiasijoitusjärjestys refers to the order in which different energy sources are used or dispatched to meet electricity demand. This concept is crucial for grid operators to ensure a stable and cost-effective power supply. Typically, energy sources are ranked based on their marginal cost, which is the cost of producing one additional unit of electricity.

The lowest marginal cost sources are usually dispatched first. These often include baseload power plants that operate continuously due to their low operating costs, such as nuclear power, hydroelectric power, and some renewable sources like wind and solar when they are available. These are followed by intermediate-load power plants, which can be ramped up and down more easily to meet fluctuating demand. Finally, the highest marginal cost sources, typically peaking power plants like natural gas turbines, are used to meet peak demand during periods of high consumption.

Factors beyond marginal cost can also influence the energiasijoitusjärjestys. Grid stability and reliability play a significant role. For instance, sources that can quickly adjust their output, like natural gas plants, are essential for balancing the intermittent nature of renewables. Environmental regulations and carbon pricing mechanisms also increasingly affect dispatch decisions, favoring cleaner energy sources. The overall goal is to meet demand reliably while minimizing costs and environmental impact.
