Technical FAQs 4

Is there a standardized procedure for solar energy development in Finland?

There is no standardized procedure for solar energy development in Finland, and it is up to the developer to find out about the obligations and responsibilities. The requirements for permitting are dependent on the size of the project, the location, the project's regional impact, the zoning plans, and other land usage plans.

Does Finland need a grid-connected battery energy system?

Finland is an international frontrunner in implementing grid-forming capabilities. Grid-connected battery energy systems are already required to have these properties in existing and future converter-dominated areas,” says Harjula.

What is a grid-connected microgrid & a photovoltaic inverter?

Grid-connected microgrids, wind energy systems, and photovoltaic (PV) inverters employ various feedback, feedforward, and hybrid control techniques to optimize performance under fluctuating grid conditions.

What is the process of connecting to the grid in Finland?

The process of connecting to the grid In Finland, all projects that meet the technical requirements have the right to be connected to the region’s grid. The grid operator’s connection terms and requirements have to be unbiased, impartial, and reasonable as per the Finnish Energy Authority.
