During the investigation, visited South Africa's ESKOM company, Brazil state power company, Argentina company, and with the related experts for communication and fruitful.

A, South Africa, Brazil, Argentina electricity market operation basic situation

1, South Africa electricity market operation

South Africa's power industry started in 1880. Later, with gold and diamond mines, coal mining and the scale of the growing, South Africa's power industry and continuous development. In 1922 the government expert

A electrical method, South Africa in 1923 founded The power supply commission (The Electricity SupplyCommission: ESCOM), to sending a monopoly power management. 1985 years after the modification of electrical, will committee form of entity of the company form reorganization to entities. In 1987 it instead as ESKOM and continue to use up to now. ESKOM no shareholders, through the loans, issuing bonds and sales income funds, belong to state-operated company. According to the 1987 ESKOM method, electric committee (Electricity Council) and Management Board of directors (Management Board) is founded. Electric committee is the highest policy-making body of the ESKOM, decided to policy, objectives, and implement supervision.

The board of directors of the business is business executive agencies ESKOM, the electric committee for policy management ESKOM affairs.

At present, ESKOM is the world's fourth most electric power production and fifth largest power sales enterprise, accounting for two-thirds of the capacity of the whole of Africa, has the world's largest dry power station, South Africa and all must supply 95% of the electricity consumption by 60%. It's power transmission network is the north extended into the adjacent in sub-saharan countries.

(1) the installed capacity and turbine

South Africa's power generation equipment in thermal power equipment mainly, at present thermal power installed capacity of the national total

The installed capacity of 89%, and the majority is coal-fired units, and a small amount of gas turbine

Group and diesel generating set. Gas wheel is mainly used for peak by the accident and set aside. Coal-fired unit capacity

In the s to 200000 kW is given priority to, the 70 s expanded to 500000 kW, 80

S further expand to 600000 kW or more. The power plant coal quality is poorer, ash is high, of sulfur

Low amount. Large coal fired power plant of building in coal mine area, the signet of power plant; And because the South Africa territory

Less river, water power difficulties, large-scale unit by almost all air cooling technology. 1966 years

South Africa in the first Grootvlei power plant no. 5 and 6 machine construction machine air cooling tower, mark#p#分頁標(biāo)題#e#

The ESKOM the first air cooling system. Construction began in 1982, built in 1993

Kendal power plant is now the world's largest coal-fired power plant, by adopting indirect air-cooled system, its

Cooling tower is the world of the largest such cooling tower. Another famous air cooling power plant is

Matimba power plant, the factory with the world's largest direct air-cooling system.

South Africa guohe river sparse, less rainfall, the development of hydropower resources can be few. The main

The two have ESKOM hydropower station a conventional hydropower station and 2 a pumped storage power station, take on the electricity

Nets peak load and as accident. Set aside.

South Africa Koeberg nuclear power station is South Africa, and is the only continent only a

Nuclear power plant. It is located in the north Atlantic side of Cape Town, equipped with 2 sets of nominal capacity for 965000

KW PWR, South Africa 1.84 million kW or supply 6.5% of the power demand. The plant

Since 1984 operation, undertake basic load, already accumulative total power generation 81 billion kW. H.

South Africa's new energy research plan by ESKOM implementation and began in 1998.

The purpose of the program is to decide the scale of practical generating new energy can become future ESKOM

And South Africa a selection of power supply side. At present, the plan includes four parts: wind and the sun

Can, unaltered and wave power generation. Wind power and solar power research progress are the fastest, will soon

To introduce demonstration project. Organisms and wave power generating research is still in its early stages of the project development

Section.

Wind power research include large wind power to Africa know the influence of the environment; The wind

Power generating the most suitable method and scale; Preparation of wind power market and industry; Survey wind

Power in Africa's sustainable development, etc. At present the feasibility study is underway, also under construction

A demonstration project.

Solar power generation technology research plan in February 2001 to finish, 2001 ~ 2003

Carrying out feasibility studies, if approved, the power plant construction to start in 2004, 2005,-

Put to use.

(2) transmission and transformation and the grid

South Africa's coal-fired power plants built in the northern part of most near coalfield, need to pass to long-distance transmission

Load transfer center. South Africa's transmission system with 400 kV and 275 kV primarily, ESKOM

Have the grid and operation of, still run 765 kV lines and dc 533

KV lines. South Africa has built a large number of current 400 kV power transmission lines of the north will pit electricity

Factory and inland and coastal cities such as the important Johannesburg, Pretoria, bloemfontein,

Cape Town, port Elizabeth, east London and durban, etc and many mines and factories serve is strong#p#分頁標(biāo)題#e#

Big national power grid. From the 60 s, South Africa with power grid has moved into lesotho, Swaziland,

Mozambique, Botswana, namibia, Zambia and Zimbabwe has United Kingdom grid

Network lines.

South Africa's distribution business ESKOM and local ZiZhiTi operation. ESKOM of the power distribution

Department is South Africa's biggest power distribution enterprise, its user accounts for 40% of all users, the sale of electricity

Quantity accounted for 57%. ZiZhiTi place in their respective administrative areas monopoly in distribution business.

South Africa is currently on electricity market reform. The South African government reorganization plan ESKOM

In order to improve the working efficiency of the enterprise. In addition to transmission business other than most business will gradually

Privatisation. The government has claimed the company 10% of power generation capacity will be completed in 2004 privatisation.

The South African government in August 1997 announced a distribution plan. South Africa will be divided into five

A regions, by ESKOM and the local government was composed of joint venture, called

REDS (at that time ESKOM 60% of the electricity directly to end users power supply).

REDS in accordance with state power management organizations (NER) issued from power generation enterprise wholesale price

(ESKOM and IPPS) buy electricity. This is to break the monopoly in gradually ESKOM first step.
