Professional and small-scale electricity production

Electricity production can be divided into professional electricity production and small-scale production. Large power plants are used to produce electricity for the electricity market. The most common small-scale electricity production plants are solar, wind and hydroelectric power plants as well as bio combustion plants.

Professional electricity production – more than 2 MVA

Large power plants are used to produce electricity for the electricity market. For example, large wind farms comprising several large wind power plants. The connection of a production plant to the electricity network will be investigated on a case-by-case basis. It is a good idea to investigate the prerequisites of a network connection as early as possible. If the network needs to be rebuilt to connect a new production plant to it, this may take several years. The connected power plants must meet Fingrid’s technical system requirements (VJV).

The connection capacity influences the connection price. When the capacity of our electricity network is sufficient and the project has a legally valid zoning plan, we can sign a connection contract with the connecting party. If the network connection is not possible, we may suggest connecting to our network in another location where sufficient capacity is available or negotiate a solution with the transmission system operator Fingrid.

Please contact us to find out the network connection capacity or to request a quote for a connection to the location of your choice.

Small-scale production – less than 2 MVA

The most common small-scale production plants are solar, wind and hydroelectric power plants as well as bio combustion plants. Small-scale production can usually be connected to an existing access place so that the electricity network does not need to be reinforced. It is a good idea to verify the network connectivity before acquiring the production equipment. The electricity production plant can be connected to Elenia’s distribution network once the production equipment has been approved for connection.

The customer is liable for the costs of building the power plant as well as the electrical works following the connection point. If the plant’s rated power exceeds the agreed capacity of the electricity connection, the capacity needs to be increased. Submit a notice using the small-scale production information form. We will send you a confirmation and the production access place ID.

Electricity production electricity tax liability

When it comes to electricity tax liability, electricity producers are divided into three categories:

  1. Operators who produce electricity using a micro power plant with a maximum rated power of 100 kVA are exempt from all electricity tax liabilities. These operators need not register as a taxpayer or fill in a tax return for their electricity production. This type of micro power plants, such as solar panels, may be owned by households, farms or companies.
  2. Small-scale electricity producers using equipment with a maximum rated power of 100 kVA who produce a maximum of 800,000 kWh annually, on the other hand, must register as taxpayers with the Tax Administration. However, they only need to fill in a tax return once a year so as to enforce the specified annual production limit. An electricity producer, a power plant with a rated power in excess of 100 kVA and an annual production of more than 800,000 kWh, must fill in a normal tax return on a monthly basis regardless of whether it feeds electricity into the electricity network or not.
  3. Operators who produce electricity using a micro power plant with a maximum rated power of 100 kVA are exempt from all electricity tax liabilities. These operators need not register as a taxpayer or file a tax return for their electricity production. This type of micro power plants, such as solar panels, may be owned by households, farms or companies.
