Probleme des japanischen Stromnetzes

Ein interessantes PDF aus dem Jahr 2004
ELECTRIC POWER GRID INTERCONNECTIONS IN THE APEC REGION http://www.ieej.or.jp/aperc/pdf/GRID_COMBINED_DRAFT.pdf
Beschreibt u.a. die Probleme des japanischen Stromnetzes
* 50/60 Hz Aufteilung * Probleme bei Ausfall bestimmter Kraftwerkstypen (z.B. Atomkraft)
Auszug:
...But power interconnections are far less developed between Japan’s electric service areas than within them. Thus, an issue has arisen with respect to what might happen to the reliability of power supply in Japan when a particular class of generating capacity has to be taken out of service...
... In August 2002, the Tokyo Electric Power Company (TEPCO) was required by the Japanese government to take all of its nuclear power plants out of service ....
... TEPCO relied on nuclear power for 29 percent of its generating capacity and 47 percent of its electricity generation in 2001, there were real concerns that power demand might not be met....
... the ability of adjacent areas to make up for power shortfalls in Tokyo on an ongoing basis would be quite limited, even if adjacent areas had as much surplus generating capacity as the capital area required.
.... In this light, it may make sense for Japan’s electricity producers to consider the available options for expanding transmission capacity across different service areas. In particular, it may be useful to compare the marginal benefit of expenditures to further elaborate transmission grids within service areas, which are already highly developed, with that of expenditures to substantially expand transmission links across service areas, which are not."
