The Tanchon Hydroelectric Project is the largest hydroelectric project in North Korean history in terms of its complexity. Using a system of tunnels running for 60 km, it takes water from the Hochon River in Ryanggang Province (drawing from the Samsu Reservoir) and redirects it to the Tanchon hydroelectric generating stations in the small village of Sinhung, S. Hamgyong Province. Once completed, it will be the fulfillment of nearly a century of planning.
Construction of the enormous project began in 2017 and continued through 2018, but work began to slow down in 2019 and that has carried on this year, particularly at the generating stations, as this update reveals.
Tunneling work, on the other hand, appears to have made substantial progress.
Near the end of 2018, you can clearly see one of the over sixty access points to the main water tunnel, where small sections of the tunnel are excavation.
Almost exactly two years later, that one pile has become two very large piles.
The two piles cover a total of over 6,400 sq. meters. While not every access point has piles as large, they have all grown substantially, giving evidence to the size of the main water tunnel.
Part of the project is the Sinhung Dam, located less than 2 km from the generating site.
Looking at Power Station No. 6, there has been a lot of progress since 2018 (when almost nothing existed), but little else new can be seen since Sept. 2019.
One of the most obvious changes is the addition of a roof over the generating hall. The outward appearance of Power Station No. 6 suggests that it is completed. However, it is unknown if the turbines and other equipment have been installed. Although, depending on their size, the turbines may indeed have been installed prior to the rood addition, and the power station could be ready to become operational.
Until Power Station No. 1 is completed, the Tanchon project won't be able to produce but a fraction of its planned capacity. The slight progress made in the last year could be due to several factors.
The year 2020 has been especially difficult for North Korea's economy, and they were forced to limit the number of projects of national importance from 15 down to just 5. The economic and trade effects of COVID-19 have become more pronounced, and it is likely that the virus has indeed entered the country. On top of that, three typhoons hit North Korea and caused severe flooding across the country, and exchange rates between the DPRK won and US dollar have fallen.
It's possible that the project will receive some added assistance as part of the flood recovery efforts in the region, but it is just as likely that it won't be completed for another year as other major projects (the Pyongyang General Hospital and the Wonsan resort area) have also blown passed their planned completion deadlines and are still under construction.
