Electric power is essential to our way of life. Both now and in the future, how to ensure the reliable supply of electric power while reducing the load on the environment will remain a challenge on a global scale. In response, Hitachi develops and supplies an extensive range of highly efficient and reliable power generation systems throughout the world.
Nuclear power does not emit CO2 in the generation process. Hitachi's global nuclear power business has the technical capabilities to deliver a full range of products and services, from the development and manufacture of equipment through to plant construction and operational support, the nuclear fuel cycle, disposal of radioactive waste, and preventive maintenance.
Hitachi is also actively involved in power generation systems using renewable forms of energy with the potential to be important sources of energy in the future. In the field of photovoltaic power generation, Hitachi not only supplies highly efficient equipment, it can also draw on the comprehensive capabilities of Hitachi to handle all aspects of megasolar power systems, from financing through to operation and maintenance. These capabilities include its power system technologies and system integration know-how built up over many years. In the field of wind power generation, Hitachi supplies wind turbines that use a highly reliable downwind turbine configuration to achieve a high level of generation efficiency in mountainous regions. It is also working on further developments, including deployment in offshore wind farms and upsizing the technology.
There is a trend in the transmission and distribution of electric power toward the use of larger-scale systems, to cope with large power plants and to reduce transmission losses through the use of high transmission line voltages. Hitachi has extensive experience in this field through its supply of highly reliable transformers, switchgear, and other products throughout the world. Hitachi has also been working in recent years on smart grids that supply electric power reliably and without waste, and that combine conventional power plants with sources such as wind and photovoltaic power generation for which output levels are difficult to control.
