Small-scale production: purchase prices by company
The table shows the terms on which electricity companies buy the surplus electricity that small-scale production (such as solar panels) feeds into the grid, from the companies' own pages. The purchase price is the spot price minus the company's fee; there may also be a monthly fee.
The decree allows a different electricity seller for a site's production than for its consumption (Government Decree 767/2021, chapter 2, section 2), but each company sets its own purchase terms: the table shows whether the company also buys from others than its own electricity customers.
