Põhisedload

Põhisedload is an Estonian term that translates to "base load" in English. It refers to the minimum level of electricity demand that is expected to be met by power plants on a continuous basis. This consistent demand is usually met by dispatchable power sources, such as nuclear power plants, coal-fired power plants, or hydroelectric dams, which can operate at a constant output for extended periods.

Base load power plants are characterized by their ability to run 24 hours a day, seven days a week, providing a stable foundation for the electricity grid. They are typically the cheapest sources of electricity to operate once built, making them ideal for meeting the constant demand. The concept of base load is crucial for grid stability and reliability, ensuring that electricity is always available even when demand is at its lowest.

The proportion of base load in a country's energy mix can vary significantly depending on factors like energy resources, existing infrastructure, and government policy. Countries with abundant access to coal or nuclear energy often rely heavily on these sources for their base load. As renewable energy sources like solar and wind become more prevalent, managing the base load becomes more complex, requiring advancements in energy storage and grid management technologies to compensate for the intermittency of these sources.
