In the field of power generators, electrical power plant has a great contribution in the world. It is popular due to having efficient and reliable form of clean source of renewable energy. But, these new technologies can be an excellent method of harnessing renewable energy from solar, wind and small rivers and lakes. This technology is mainly designed to be a run-of-river type, because requires very little or no reservoir in order to power turbine. That technology Increases the efficiency. This technology means that, the three non-Conventional energy sources producing electrical energy. This has a minimal environmental impact on the local ecosystem. This technology is applied in Hydro power plant. The output for the power generation is also increases
