Rosseti and GEC of China will connect Russia with the PRC with energy bridges
Yesterday Rosseti and the State Grid Corporation (GEC) of China signed an agreement on strategic cooperation. It involves the construction in Russia of ultra-high voltage AC and DC lines and substations, as well as the possible construction of "energy bridges" - DC transmission lines from Russia to China. Within 30 days, a working group will be created that will determine the characteristics of the lines between the power systems of China and Russia, they say in Rosseti. Energomost will be focused on unidirectional deliveries from Russia to China, but then it is technically possible to organize a bidirectional transmission, according to the company's press service.
As for the routes, then about ten working projects are considered, say in “Rossetah”. The annual transmission volumes for which the project is designed in its completed form are estimated at 2-5 GW in the PRC. The supply base will be both the existing power plants in Siberia and the Far East, as well as the new generation construction projects that are planned for implementation, which are focused on supplies to China, explained in Rosset.
Among the potential builders of this generation are Inter RAO, which announced plans to create a large Yerkovetskaya TPP (5-8 GW), RusHydro, whose plans for flood control hydropower plants in the Amur basin depend on the Chinese market, En + and TGK-2, which have agreements with China on the development of exports.
In the context of the construction of the Erkovetskaya TPP, it was reported about the intention of the GEC to build an 800 kV power transmission line to Beijing. The construction of 2 thousand km of such a transmission line from the station was estimated at € 1,2-1,5 billion, excluding the landscape. Now it is planned that the construction of 800 kV transmission lines and substations in Russia will be carried out using Chinese equipment and technologies. Rosseti offered GEC to participate in the modernization of power grids in Russia, including in the field of construction, network management, and in the supply of equipment, including with the localization of production.
