Small-scale Electricity Production

Electricity consumers as electricity producers

Small-scale electricity production is most efficient when the generation plant is designed especially for the site. By sizing the system to minimise the amount of solar electricity fed into the grid, most of the electricity produced can be used by the site itself. Depending on the production method, you may need a permit from your municipality. You can check the status of the permits required from your local authority.

We need to know how much small-scale electricity is coming into Elenia's network in order to measure the electricity produced and ensure safety. Inform us of the installation to the electricity grid well in advance by using the Small-scale production information form (in Finnish only). Once your form has been processed, we will confirm the installation to the grid.

Below is an example of filling in the small-scale production information form.  You need your Elenia customer number to fill in the form. You can find the customer number on your invoice.

Selling left-over electricity

If the system is connected to the electricity network, you can sell any excess electricity generated by your solar panels. You can feed your excess electricity to Elenia’s network and make a sales agreement with your supplier. We will send you a confirmation and the production access point ID. A good place to compare electricity suppliers is the Energy Authority’s website www.sahkonhinta.fi .

Netting of small-scale production

Netting means adding up the electricity taken from and fed into the network during the metering period. When electricity is purchased and produced at the same time, the amount of electricity produced directly reduces the amount of electricity purchased. Netting will only be carried out on sites with an electrical output of 100 kVA or less. Netting also requires that the property has both an electricity sales and purchase agreement with the electricity supplier. Elenia introduced netting to their customers at the beginning of 2023. As our customer, you can monitor the amount of electricity consumed through the Elenia Aina -service.

An example of netting in practice

During one hour, 2 kWh of electricity is consumed, and at the same time a 4 kW solar panel system at full power produces 4 kWh. After netting, consumption for this hour is 0 kWh and production 2 kWh. During the next hour, heating the sauna increases the electricity consumption to 8 kWh, and because of rainy weather the electricity production is reduced to 0.5 kWh. After netting, consumption for this hour is 7.5 kWh and production 0 kWh.
