Yes, it's perfectly fine to sell the surplus. But remember that in order to sell
and to get paid for the electricity certificates, you must have a wind turbine that produces at least 1,000
kWh/month, since the minimum sales volume is 1 MWh/month. If the plant produces 50,000 kWh/year or
Furthermore, it is generally profitable to sell both electricity certificates and surplus electricity via separate meters.
The cost of reporting the electricity certificates is around 2,000 SEK per year, so a
total production of at least 10,000 kWh/year before that cost is paid off. In practice, you need
a plant that produces significantly more so as not to risk production falling below 1
MWh/month!
