Määrätuule

Määrätuule is a concept in Estonian law and wind energy development. It refers to a legally defined wind speed that is considered necessary for the economically viable operation of a wind turbine. This threshold is crucial for determining whether a particular location is suitable for wind power generation and for obtaining permits for wind farms.

The concept of määrätuule is integrated into the Estonian Renewable Energy Act and related regulations. It takes into account various factors, including the energy output of the turbine at different wind speeds, the operational costs, and the expected revenue. The specific value of the määrätuule can vary depending on the technology used and the economic conditions, but it is generally set at a level that ensures a reasonable return on investment.

When assessing a potential site for a wind farm, developers must demonstrate that the prevailing wind conditions meet or exceed the established määrätuule. This often involves extensive wind measurements and modeling over a period of time to provide reliable data. If the wind speeds are consistently below the määrätuule, the project may not be deemed economically feasible, and permits may be denied.

The määrätuule serves as an important regulatory tool to guide the development of wind energy in Estonia, aiming to promote sustainable energy production while ensuring economic viability. It helps to differentiate between marginal sites and those with genuine potential for effective wind power generation.
