Microgenerator
A microgenerator (mikrotootja) is, per Elering's electricity-market handbook glossary, an electricity consumer who produces electricity primarily for their own use with a generation device of up to 11 kW. The English term "prosumer" is used for the same concept. In Estonia the typical microgenerator is a household with rooftop solar exporting surplus to the grid through the same connection that draws consumption.

Connection rules
Microgenerator status is established at connection time with the DSO (in most cases Elektrilevi) and unlocks a simplified connection process — single-phase or three-phase, no separate BRP requirement, no balancing-market certification. The household's open supplier handles the wholesale-market consequences of net consumption or net export at the meter.
How exports get paid
Two structures coexist. Net-billing customers settle exports against imports inside the same hour; surplus beyond hourly import gets paid the Nord Pool day-ahead spot price for that hour, minus a small marketing margin to the open supplier. Fixed-price customers receive a contracted feed-in price agreed with their supplier. From 2026, Estonian network and renewable charges are calculated on net consumption rather than gross — a major economic improvement for microgenerators that has materially shifted the rooftop-solar payback case.
