Wind farm power generation indicators

Why should the wind energy industry use financial KPIs?

This should be a common goal of the wind energy industry and academia for the future. All discussed financial KPIs fulfil the necessary properties and can be used as they are, allowing to reveal variations in the financial status of the asset. An overview over the proposed indicators and their properties can be found in Table 2. Table 2.

What is a wind farm operator?

Wind Farm Operator The WF operators’ main interest is to maximise the revenue of the WF and hence the energy production throughout Elena Gonzalez et al. / Energy Procedia 137 (2017) 559–570 561 Gonzalez et al. / Energy Procedia 00 (2017) 000–000 3 the lifetime of the project.

Who owns a wind power project?

The Investor Investors and banks can partially or completely own the WF. They are mainly interested in the economic and financial aspects of the wind power project development, including information about production, efficiency, future expecta- tions, costs, debt, profits and current value of the asset.

How reliable is a wind turbine?

Applied to a WT, its reliability can be defined as its ability to perform properly, without failures, during specified site wind conditions for the whole lifetime (defined to be at least 20 years) or in a specific time window. WT reliability is compromised by component failures, leading to downtime.

Is the denominator a useful indicator for evaluating WF operational efficiency?

Since the denominator is a constant, it does not represent the theoretical energy production according to real on-site wind conditions. Although it is a valuable indicator during feasibility and wind project development stages, we believe it is not an effective indicator for evaluating WF operational efficiency.

Who buys wind energy?

Utility and Grid Operator According to the European grid codes, all the energy produced from wind has to be bought by an electrical compa- nies, i.e a utility. This stakeholder is usually interested in the energy production of the WF, the future expectations of production and the electricity price.
