Interconnections of
Russia with
countries of
Northeast Asia
in the framework of
possible electricity
unification
The study is being conducted by Energy Systems Institute of Siberian Branch of the Russian
Academy of Sciences in collaboration with Skolkovo Institute of Science and Technology and
EN+ Group.
Projection of prospective electricity
demand for Northeast Asia (NEA)
countries and regions, TWh/year
Electricity demand in the region is expected to grow more than twofold for the considered period.

Scheme for potential power system
interconnections in Northeast Asia
This scheme is modeled and studied. Considered were base case
with no power system interconnections (as now) and case of full
integration when no constrains are imposed on power flows among
countries. Optimization expansion planning model ORIRES was
applied for the study.
9
Benefits for the power system
interconnection in NEA region
The main benefits for the entire NEA power system interconnection were calculated as difference
between the indexes for the base case and integration case. They are quite sufficient. For example,
capacity saving benefit is equal to three quarter of the current generating capacity of Republic of Korea.
