Sharing solar power in Norwegian housing and business areas
Energy sharing allocates locally generated renewable electricity between eligible metering points. The grid company registers the arrangement in Elhub. Housing associations and business areas must establish property boundaries, participants and generation before sharing can start.
Solar sharing in housing associations
The same-property arrangement follows Norway’s municipality and cadastral identifiers. Participating generation is limited to a combined 1 MW AC per property. Confirm meter configuration and recipient eligibility with the grid company.
Sharing between buildings in a business area
A separate arrangement for qualifying business areas took effect on 1 January 2026. It covers up to 5 MW AC of renewable generation on areas already developed for another purpose. The area must be geographically defined, with cooperation, common functions and shared infrastructure. Proximity alone is insufficient.
How is solar electricity allocated?
Elhub calculates allocation using the registered model. Examples include equal shares, agreed percentages and dynamic allocation. Production sharing is a settlement arrangement; it does not provide island operation or a private wire to each recipient.
What should the board or property owner establish?
A sound decision identifies who invests and who benefits. Prepare material the board, property manager and adviser can use, with clear operating and allocation agreements.
- Map properties, the generation meter and possible recipient meters.
- Assess roof suitability, condition and planned maintenance before sizing solar.
- Compare consumption and generation across the year and day.
- Agree ownership, cost allocation, the price of shared energy and administration.
- Plan for occupancy changes, altered consumption and future extensions.
- Establish decision-making authority and required resolutions before ordering.
Do you need a battery to share solar?
A battery is separate from the sharing arrangement. First assess whether solar can be used when produced. Then consider whether storing surplus adds value compared with sharing or exporting it.
For example, do residents use most electricity after solar output falls, while common-area demand is low during the day? Compare system sizes and storage against actual meter data. Grid electricity stored in a battery should not automatically be treated as shareable locally generated solar.
What happens to the electricity bill?
Separate purchased electricity, grid charges, taxes, payments for shared energy and system costs. A high share of local generation does not imply the same reduction in the total bill. Request calculations for each recipient type and confirm tariff treatment with the grid company.
Enfy can assess solar, battery and control as one project. Registration and approval of the sharing setup must go through the grid company. Sources below describe the framework checked on 7 September 2026.
Questions and answers
Can we share solar electricity with a neighbor?
This depends on the property, area boundary and remaining conditions. Ask the grid company to assess the actual metering setup before including sharing in project economics.
Will all grid charges disappear?
No. The bill has several components and the effect depends on meters, tariffs and allocation. Calculate the impact on recipients and common facilities separately.
Can Enfy help our housing association deliver the project?
Enfy brings together assessment, engineering, installation and energy management. Bring metering details, consumption, property information and the board’s objectives for an initial discussion.
