Rīgas HES
From Wikipedia, the free encyclopedia
Riga's Hydroelectric Power Plant is located just beyond Riga's southern border. It is geographically located in the town of Salaspils. Total installed power generating capacity is 402 MW.
In order to build Riga HES, a dam was constructed across the Daugava River through the middle of Doles Sala, half of which has since been flooded to make room for Riga Reservoir. Along with Doles Sala, there have been several other smaller islands drowned in order to fill the reservoir. The dam was built in the late 1970s. Aside from its main purpose of keeping the reservoir contained, its top is being used as a motor vehicle highway. A railroad has also been constructed on the dam, but it has never been utilized and have been demolished in beginning of 21st century. This is because there are no existing railroads on the Daugava's left shore. This railroad began at Salaspils railway station, and ended at approximately middle of Doles sala.
Rigas HES is an important part of Riga's development. It is the primary source of electricity in Riga, while Riga reservoir is a source of tap water for the majority of Riga residents.
