1
Energy sector activities and Plans in the DPRK

• (presentation by the DPRK delegation)
• May,13-16, 2005, AES Workshop, Beijing

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

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 46 (previously 55)

6

• Technical renovation of thermo power plants
• Increase conversion rate
• Continue construction of various types of hydro
  power plants
• Optimal use of wind power

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

8

• 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

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
