ANEEL Resolution 024/2000, in its Article 8 gave 06 parameters for defining sets: 1) area, 2) primary extension, in square km, 3) the average monthly energy consumption in kWh over the past 12 months, 4) total consumer units served, , 5) the generating capacity in KVA and 6) belongs to the interconnected system. To the sets were assigned quality goals to be achieved over time. In 2004 was created ANEEL Resolution 063 establishing fines for the sets that fail to achieve the defined objectives. The hypothesis of this dissertation is that the effects of corrosion caused by pollution and salinity cause significant impacts on services costs and that the use of new materials and equipment improves the quality indexes with a lower cost than the conventional ones. The different standards used for network construction which Coelba uses in the metropolitan area of Salvador and Porto de Sauipe due to the effects of salt and industrial corrosion, so as to ensure the quality indicators defined by ANEEL are shown. An experiment was set at Paripe substation, located 2 km away from the seafront, on Aratu Bay, in the metropolitan area of Salvador, with a meteorological station, chloride collectors, a portable particle sampler and a leaking current capture system on many 15 kV insulators, as well as material taken from the field for laboratorial analysis, with the aim of evaluating the degree of corrosiveness of the region. In Coelba there are 05 sets with the same characteristics, being made relative comparisons between the adopted standards due aggressiveness degree and different operating costs. This study concludes that we have to adopt standards for differential electric power distribution in places with increased corrosion levels, to ensure a more appropriate cost of electric service for society. The monitoring of regions with high corrosion is imperative so that we can assess the materials and their performance over time, As we adopted mitigation measures to reduce the maintenance cost and increase the availability of electric power. There are municipal or federal definitions that directly affect the power network standards and the costs of maintenance and operation, as an example, the areas of heritage buildings and environmental preservation.
