Regional integration

Regional integration incorporates to the study aspects of market, social, sociological and political order to determine the penetration of each technology. Additionally, it is considered the competition between technologies for the use of space to avoid the introduction of several technologies on the same site.

To assess the implementable potential in each location the following land use restrictions are taked into account:

  • Geographical restrictions: In addition to the considered restrictions in the potentail evaluation for each technology, in implementation analysis areas under permanent crops, irrigated areas and rainfed low productivity (less than 500 mm rainfall year) are discarded.
  • Environamental restricions: in the implementation analysis non-protected forest areas are discarded.
  • Economical restrictions: it is considered a minimum size for each facility and each technology is evaluated based on the quality of the resource in one location and the cost of generation.

Results

In the following figure the considered land use restriccions in the regional integration of renewable energies are presented.

In regional integration waste biomass resources from agricultural and forest residues are considered. As for the rest technologies the area under cultivation technology has been considered as a geographical restriction, the biomass does not compete for land use with other renewable sources.

The figure below represents the geographical distribution of crops and forests in Andalusia, as well as the location of the energy plants from these farms.

Solar and wind power are in competition for the available space, so for each site the implemented technology is selected based on the quality of the resource and the production cost.

Offshore wind energy and wave energy do not compete for space use, therefore the available energy potential of the higher resource quality technology is considered in the regional integration

The following image presents the integration of wind, solar and wave energy on Andalucia autonomous region.

It is noteworthy that the onshore wind power and solar do not compete for space with biomass energy, because of that, the total potential presented on the previous two images would be implementable.

The figure below represents the visual impact caused by wind farms in Andalucia autonomous region. The area visually affected corresponds to the locations where a wind facility could be seen.
