SIGA SOL — Planning module

The planning process for the insertion of renewable energies in rural areas is normally a complex task because it demands an approach with multiple criteria: energy resources, socio-economic

indicators, indices of non-electrification, among others. If we addiotinally consider the intention of stimulating regional development through the inclusion of energy systems for productive aims, we have to consider the aptitude of the soil for diverse cultures and the existence of hydric resources.

The SIGA SOL planning module was constructed considering these conditionals and the possibility of analyzing the possible combinations of criteria defined by the user for locals for the implantation of new renewable energy systems.

The SIGA SOL functionalities for macro-spatial planning are basically constituted of the following blocks:

IDH and index of non-eletrification;

Areas of exclusion;

CPRM wells;

Aptitude for sugar cane, quantity of produced cane and capacity of electric energy generation with sugar cane bagasse;

Aptitude for castor bean plant, period of planting and biodiesel plants;

Energetic forests;

Wind direction and intensivity, promising area and capacity of electric generation by the wind; Monthly solar irradiation on the horizontal plane and solar irradiation on the collector plane in the month of minimum irradiation.

Fig. 8 (a) shows the municipalities of Pernambuco that have income per capita less than US$100. The IDH sub-menu permits the obtention of maps with other additional social indicators. The areas of exclusion are defined as indigenous, ecological reserves and special areas of preservation. They are considered areas of exclusion when one wants to localize conventional energy systems or large scale renewable energy systems. In the case of localization of small scale and distributed renewable systems, such areas must be considered as maximum priority. Fig. 8 (b) shows these areas for Pernambuco.

Fig. 9 shows all the subterraneun wells cadastred by CPRM in the state of Pernambuco. A more detailed filtering through a menu permits the choise of some specific aspects as depth or finality. In yellow, for example, wells of depths greater than 30 m.

Fig. 10 shows from top left to bottom the aptitude of sugar cane culture in two distinct scenarios: dry and rainy period. On the right, using the same convention to aptitude for castor bean plant. Fig.
