Microproduction
We compensate for electricity generated by a microgeneration facility, like solar panels, primarily through net metering. If generation exceeds consumption, the surplus electricity can be sold to Keravan Energia.
Surplus from microgeneration is sold under a purchase agreement
When electricity generation equipment—such as solar panels or a wind turbine—with a nominal capacity of up to 100 kVA is connected to a property’s electrical system, this is referred to as “microgeneration.” If the amount of electricity generated exceeds the amount consumed on the property, the surplus electricity can be sold to an electricity company by entering into a purchase agreement.
We provide compensation for electricity generated by a microgeneration system primarily through a net-metering (netting) arrangement. If generation exceeds consumption, the surplus electricity can be sold to Keravan Energia.
As the grid operator, we enter into a grid service agreement for electricity generation with all our customers who generate electricity. This agreement entitles the customer to sell the electricity they produce and feed it into the electricity distribution grid. Before the agreement can be established, the equipment must be installed and approved by the grid operator. The property’s main fuses must not exceed 63 amperes. Producers with a capacity of less than 100 kVA are exempt from tax liability.
How to connect a microgeneration facility to the electricity grid
Anyone planning a microgeneration facility must contact three parties: the municipal building control authority, the electricity network company, and an electrical contractor.
Connecting solar panels or other microgeneration equipment to the electricity grid requires a valid purchase agreement for the electricity produced.
Steps:
First, ensure that you have the necessary permits for your micro-generation system. Some equipment requires a building permit or a permit for minor construction work from the building control authority.
Please contact us well in advance. We will help you ensure that the equipment you are planning to acquire meets the required standards. We require that grid-connected micro-generation systems be equipped with a safety mechanism that prevents the supply of power into a de-energized grid.
An improperly installed micro-generation system can pose a danger to both the user and electrical grid technicians, as the equipment might feed power into a line assumed to be de-energized. The electricity producer is liable for damages if their equipment causes harm to the electrical grid or to other users of the grid.
Contact an electrical contractor. You must not install equipment that connects to the electrical grid yourself; the work must always be performed by an electrical contractor. Complete the general information form for micro-generation together with the contractor at least two weeks before the desired commissioning date. Note: the form is in Finnish.
New microgeneration equipment cannot be connected to the electricity grid without a valid microgeneration purchase agreement. You may enter into a microgeneration purchase agreement with us or with another electricity retailer of your choice. Please note: Keravan Energia requires that you have both a microgeneration purchase agreement and an electricity supply (sales) agreement with us. Please arrange the purchase agreement two weeks prior to your desired commissioning date.
