Electricity generation

Interest in on-site electricity generation has increased in recent years, and more than 12,000 power plants have already been connected to Caruna's distribution network, most of which are solar power plants on or near houses. Thanks to the energy transition, almost all new power plants use renewable energy sources.

Electricity generation is divided into small-scale generation and professional electricity generation

Small-scale generation is suitable for individuals and companies, and there are plenty of solutions available on the market to meet their needs. The most common forms of power generation are solar power, wind power and small generators, such as biofuel plants. Customers normally use the generated electricity to cover the electricity consumption of their properties. Any electrical energy exceeding the amount consumed on the site can be sold to the electricity market via the selected electricity supplier.

Professional electricity generation concerns large power plants that generate energy for Finland's electricity market. These include large wind and solar farms, as well as electricity storage solutions. 

Connecting production equipment to the electricity network

Small-scale electricity production is usually connected to the customer's existing accounting point. The electrical energy you generate will be metered via the same electric meter, and the volume of energy generated will be deducted from the volume consumed in the same period.

You may consume less electrical energy than you generate in the same period, leading to surplus electricity. You can sell the surplus electricity to your chosen electricity retailer. You need an agreement on the sale of surplus electricity before we can grant you permission to connect your equipment, even if you have chosen equipment with optimal output.

If you plan to sell the electrical energy you produce to the market or increase the fuse size at your accounting point due to production, you may need a generation connection. A generation connection is an electricity connection primarily intended for producing electricity for the market. It may supply the electricity consumed by the generating equipment, as well as other consumption that is covered by the electricity produced.

Alternative types of electricity production

Most of the small-scale power plants connected to Caruna's distribution network use solar panels to capture energy from the sun. Most solar power plants are connected alongside houses or agricultural buildings that have several solar panels installed on their roofs. The electricity generated by solar panels can cover some or all of the property's electricity consumption. Solar power can also be used to charge electric cars.

If you plan to produce electricity yourself using equipment other than solar panels, contact our customer service team to check the technical implementation of your power plant.

Energy community

Housing companies can begin producing their own electricity more flexibly by setting up an energy community. Previously, housing companies were only able to produce electricity to cover their property's own needs, such as providing power for shared areas, technical equipment and lighting. Setting up an energy community enables residential and commercial units to consume the electricity generated. The electricity generated by the housing company can be divided among the members of the energy community by calculating the applicable proportions – it is not necessary to change the electric meter connections. The jointly generated energy is divided among the members of the energy community in the agreed proportions.

Any small-scale electricity producer can establish an energy community. These can also include shopping centres, campus areas and agricultural properties with several meters.
