Power plant block

A power plant unit is in contrast to the busbar power plant a single technically complete power plant , which in a group of several at a common location can be erected, from which manages all of the blocks. This form of organization is chosen because today's steam boilers and steam turbines cannot be built of any size. Another reason is that necessary maintenance work or damage to a component required for the regular operation of the power plant block does not have any serious effects on the supply of electrical power, since other power plant blocks can be switched on for the failed block and thus form a reserve .

A typical example of the organization of several power plant units at a large power plant is in Gelsenkirchen located coal power station Gelsenkirchen-Scholven . Here were seven blocks with a total of 3800 megawatts of installed capacity .

In conventional thermal power plants, up to ten blocks are often combined into one large power plant, while in nuclear power plants there is often only one block. In Germany, no nuclear power plant consists of more than two units; abroad it can be up to seven units.

The largest nuclear power plant site in the world is the Japanese Kashiwazaki-Kariwa with seven blocks, in Europe there are the nuclear power plant Zaporozhye and the nuclear power plant Gravelines with six blocks each.
