smaller but important development was the upgrading of China’s Jiangxia tidal power plant
originally established in the 1980s from 3.9 MW to 4.1 MW following the upgrading of one
of its turbines.
Ongoing developments
These developments along with a host of smaller scale projects have resulted in
approximately 521 MW of tidal range capacity worldwide with another 1.7 GW under
construction (Figure 15). At present there are two large tidal range projects under
construction, both in the South Korean Yellow Sea: The Incheon Tidal Power Plant (1.3
GW) and Saemangeum Reclamation Project (0.4 GW). The former is set to go live in 2017
and together these projects will more than triple existing capacity.

Forthcoming developments
Over 13.7 GW of tidal range is currently planned for deployment, however only 0.7 GW of
this has received consent. Major projects include the 0.42 GW Ganghwa Tidal plant
consented in the East China Sea, South Korea and the 0.24GW Turnagain Arm Tidal
Electric Generation Project in the Kenai Peninsula, US.
