1. Energy sector activities and Plans in the DPRK
(presentation by the DPRK delegation)
May,13-16, 2005, AES Workshop, Beijing
11/23/2018

2. Past Activities
Until late 20th century, priority was given to building an independent power industry based on coal and hydraulic resources
Coal deposit; 4.3 Gtoes, Hydraulic resources; 49 Twh, wind power resources; approx. 26 Twh
Till the end of last century, coal was considered to be a major energy resources
Coal accounted for 80% of total domestic energy consumption, of which 50-60% were used for generating electricity and the rest for industries and population

3. Urgent requirements for energy security in 21st Century
Upgrade existing coal-fired power plants -which were built in ’60s and ’70s
Find a solution to satisfy diverse energy needs and to ensure energy security

4. Measures followed to meet energy needs
Built self-reliant nuclear power industry
Enormous investment made for the construction of environment-friendly hydraulic power stations
Priority given to the large-sized hydro power plants in construction projects, along with a massive campaign to build small- and medium- sized plants
Stepped up technical modernization of existing thermal power plants
11/23/2018

5. Consequently, coal consumption reduced down to 60%
Hydro power consumption increased 40% from previous 20%
Generating ratio of thermal power to hydro power currently stands at 4:6 (previously 5:5)

6. Technical renovation of thermo power plants Increase conversion rate
Continue construction of various types of hydro power plants
Optimal use of wind power
11/23/2018

7. Plans for utilization of various energy resources
-Hydro power energy
Goal is to increase turbine efficiency up to 96%
Build new hydro power plants
Continue construction of 5kw small wind power stations in rural and remote areas
Develop a new technology to manufacture 100kw wind power plants
11/23/2018

8. New energy resources of special priority
Encourage joint venture with developed countries to manufacture over 500kw capacity wind power plants
-Tidal power energy
New energy resources of special priority
Field survey already finished on areas where large potentials of wind power exist
In-depth research on wind condition in these areas currently underway assisted by the International Environmental TV Group(NGO), which provided wind log
Plans are to complete construction of ongoing tidal power plant for demonstration, develop a cross-flowing turbines with over 65% efficiency

9. Energy saving measures
Constant work has been done for the introduction and application of energy saving technology
High efficiency in energy transportation is an important factor to ensure national and provincial energy security
Coal transportation was done mainly by either train or truck
Reduction of transportation and power transmission distance is an effective way to increase transportation efficiency
11/23/2018

10. Transportation efficiency
Feasibility study took place with the help of “enterprise relocation program” and “electricity calculation program”
Based on the final result of feasibility study enterprises are expected to be redeployed in the future

11. Upgrading power transmission system
With the aim of promoting balanced development at provincial level and efficient energy distribution;
Considerable investment made for the improvement of power transmission system in a more reasonable way
Investment made also to increase transmission voltage and to maintain an uniform output voltage of 2.2kv

12. Efficient central heating system to address tension created in coal supply and demand
Research work underway focusing on how to intensify heat insulation mechanism and decrease co-efficiency of heat loss down to 0.35 w/m2 k
It is envisaged to cut down drastically the volume of carbon dioxide deflation from thermo power plants for cleaner district heating
A shift from existing direct heating system into indirect heating system is planned
Further attention will be directed to overall technical renovation of facilities in energy sectors
