Features of NEC Power System. I
Current generating capacity - 38 GW, electricity
consumption - 154 TWh/year, frequency - 50 Hz
Maximum electric load comes in winter
Electricity consumption is unevenly distributed on
the territory, with large share falling on South
Large share of generating capacity is located in
South
There is currently excess of power generating
capacity

Features of NEC Power System. II
Thermal power plants dominate in generation
capacity mix
There is lack of maneuverable generating capacity
for meeting cycling electric load of consumers
Backbone power transmission grid of highest voltage
is developed
NEC power grid has local scale electric connection
with RFE EPS

Benefits for NEC from joining ‘RFE-DPRK-RK” power interconnection Saving capacity at the cost of seasonal diversity
power exchange with EPS of RK
Receiving maneuverable hydropower from DPRK
Getting profit from electricity trading with RK in
seasons of low power loads of domestic consumers
Relieving environmental burden in season of highest
winter loads at the cost of receiving power from RK
Increase of reliability and sharing reserve margin

The Method of StudyNet Profit =Gross Benefits - Gross Costs
Gross Benefits - capacity saving, reduction of electricity tariffs and environmental benefit owing to power interconnection accumulated for 15 years
Gross Costs - cost for construction and maintenance of transmission and converters accumulated for 15 years

Inferences
NEC joining to “RFE-DPRK-RK” power interconnection seems to be mutually beneficial for all participating countries.
There is quite developed transport and power grid infrastructure along the larger part of potential route of “RFE-NEC-DPRK-RK” ISET
As preliminary studies shows, the examined variants of the ISET ensure high economic benefits; such inference was drawn independently by both RK and Russian researches
It seems reasonable examining “RFE-DPRK-RK”
ISET, with section “DPRK-NEC” being extended
