Individuals can invest in hydroelectric power plants.
Investment context:
As the production of electricity from renewable resources gradually becomes a national development strategy, the State encourages private investments in this domain.
Investment form:
Realize electricity production in the form of a micro-grid. In a local area, such as a community, factory, township, etc., a microgrid system can be established to provide electricity, heat and cooling to local loads, thereby enabling operation efficiency of renewable energies.
Connected to the local electricity network. During the investment process, attention should be paid to negotiating grid connection conditions, technical issues and grid electricity price with the power system.
Pro principleHydroelectric power generation:
Use the potential energy held by water at high altitude to convert kinetic energy to drive the main engine.
Use guide waterways and pressurized water pipes to convert the potential energy of the water volume into kinetic energy.
Advantages of hydropower:
The efficiency of hydropower can reach more than 90%.
The unit output energy cost is low.
Power generation starts quickly and can be completed within minutes.
Disadvantages of hydropower:
Unable to develop large capacity due to terrain constraints. The capacity of a single unit is around 300 MW. ?
The construction period of the factory is long and the construction cost is high.
Because it is located in a natural river or lake area, it is easily affected by disastersfeng shui phenomena, climatic drought and rain.
It is not easy to increase the capacity once completed.
Water flow from hydroelectric power plants is measured through flow stations or hydrological observations located on rivers or canals. For measuring water flow, several methods are proposed in the experimental standards of the International Electrotechnical Commission. The commonly used methods are: flow meter measurement method, volute pressure difference measurement method and ultrasonic measurement method.
