Largest Nuclear Reactor Unit by Gross Electrical Capacity

Taishan 1 in Guangdong, China, is an EPR-1750 unit rated at 1,750 MWe gross and 1,660 MWe net, commercially operating since 13 December 2018. Taishan 2 has the same registered gross capacity, so Taishan 1 cannot be treated as a unique holder.

Overview

Archive Note

The World Nuclear Association reactor database identifies Taishan 1 as an EPR-1750, first connected to the grid on 29 June 2018 and commercially operating from 13 December. Gross capacity differs from net electrical capacity.

The same database lists Taishan 2 at 1,750 MWe gross, commercially operating since September 2019. The two units must be treated as a potential tie, and a global survey of comparable units is still necessary before an unqualified worldwide ranking.

Evidence & References

Verification basis and limitations

Evidence-backed

Credible sources support core facts; the comparison scope or corroboration remains incomplete.

Basis: corroborating reliable secondary materials

The WNA database lists both Taishan 1 and 2 at 1,750 MWe gross and 1,660 MWe net. Unit-level evidence verifies these ratings but not an exclusive global maximum, so developing status and limitations are retained.

Ranking confidence
Uncertain

Comparison boundaries still under review

World Nuclear Association data confirms both Taishan units at 1,750 MWe gross, but the cited unit pages alone do not establish that no operating reactor worldwide has a higher gross rating. A global comparison is still needed.
