The reactive power capacity calculator helps assess the reactive power capacity of a solar power plant already during the planning and dimensioning phase. Reactive power is a key part of a successful grid connection, as its management affects the technical feasibility of the solar power plant and the fulfilment of the grid operator’s requirements.
With the calculator, you get an indicative view of how the main components of the power plant, such as the main transformer, cabling, step-up transformers and inverters, affect the production and consumption of reactive power at the connection point.

Frequently asked questions about reactive power and the reactive power capacity calculator
Reactive power is an important electrical quantity for the operation of the power grid. It is linked to voltage control and the technical functionality of electricity transmission. In a solar power plant, reactive power affects how the plant operates in relation to the grid operator’s requirements and the technical conditions at the connection point.
Reactive power should be considered already in the planning phase, as it affects the feasibility of the grid connection, the dimensioning of components and possible compensation needs. When reactive power is assessed early, potential technical challenges can be identified before they affect the project schedule, costs or technical solutions.
The reactive power capacity calculator can be used to assess the production and consumption of reactive power at the connection point of a solar power plant. The calculator helps illustrate how components such as the main transformer, cabling, step-up transformers and inverters affect the plant’s reactive power capacity.
The calculator is intended for solar power project developers, designers, technical experts and other energy sector operators who want to assess reactive power as part of grid connection planning and dimensioning.
The reactive power capacity calculator does not replace detailed electrical design or a project-specific expert assessment. It provides an indicative estimate that helps identify the need for further studies, more detailed dimensioning or compensation solutions at an early stage.

What can you do with the reactive power capacity calculator?
With the reactive power capacity calculator, you can assess the reactive power curve of a solar power plant and review how different input values affect the production and consumption of reactive power at the connection point. The calculator supports the preliminary technical assessment of a solar power plant and helps illustrate the impact of selected components on the overall system.
The calculator can take into account, for example:
- the rated power of the solar power plant
- technical input data for the connection point
- main transformer values
- medium-voltage and low-voltage cabling
- step-up transformers
- the number, rated power and reactive power limits of inverters
- the impact of components on reactive power production and consumption
