NCRE (Non-Conventional Renewable Energy)

Non-Conventional Renewable Energy projects (NCRE) are those who, in addition to using renewable resources for the generation, have minimal social and environmental impacts. Examples of NCRE projects: plants organic waste, small hydro passing, wind farms, solar plants, biomass cogeneration plants, etc.

Types of ERNC


Type of energy obtained from organic and biodegradable material. It can be used directly as fuel or converted into other liquid, solid or gaseous biofuels.


Small scale type energy obtained from water plants whose maximum power is less than 20,000 kW (established by DFL 4-2006). The environmental impact of these plants is very low. The small-scale hydropower can be developed from natural channels, or associated with existing irrigation works (dams or irrigation channels). These plants convert the kinetic energy of the flow into electrical energy by a turbine and an electric generator.


Type of energy obtained from the wind force and motion. Wind turbines convert the kinetic energy of the wind into electricity.


Type of energy obtained from solar radiation. Is the one that came from the direct use of the radiation emitted by the sun, transforming it into heat through thermal collectors or by photovoltaic cells into electrical energy.


Type of energy that is produced by the movement of tides, waves and currents, as well as by thermal gradient of the seas. This energy is harnessed by turbines, which moves the mechanics of an alternator that generates electricity. Finally, the alternator is connected to a central ground that distributes power to the community and industries.


Type of energy obtained from the natural heat of the earth. Geothermal reservoir is a low surface area where rocks are high temperature, high permeability and saturated with fluids.

To tap the geothermal resource that is in depth, it is necessary to drill wells to extract the fluid is transporting energy from the hot rock. Once on the surface, the fluid is separated into a vapor, which is sent to a power plant, where finally the heat energy is converted into electrical energy.

The Wind projects can be classified as:
