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

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 11/23/2018

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 11/23/2018

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

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) 11/23/2018

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

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

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 11/23/2018

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

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 11/23/2018

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 11/23/2018

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 11/23/2018
