The objective of this study is to evaluate the potential for electricity generation in the State of São Paulo (SP) from the sewage treatment. A sewage treatment plant (STP) with domain in the production of biogas from wastewater treatment plant (WWTP) is the basis for this case study. The basic premise is that the very generation of electricity in STPs is advantageous for companies in the sanitation sector in Brazil, resulting in cost reductions of the treatment process. Gains at the end of the process are found in two levels, namely: (i) economic, by generating 165% of electricity from biogas burning in relation to the expend; (ii) energy, by adding a new sustainable and storable energy source equivalent to 4% of natural gas offered in the State of SP and 0,5% of electricity produced from biogas burning in relation to electricity consumption. In conclusion, the potential of electricity production linked to the biogas at STPs is capable of supply its domestic demand and export the surplus to other segments of the state and national economy.
本研究旨在评估从污水处理中发电的潜力圣保罗州（SP）。一个具有从废水处理厂（WWTP）生产沼气能力的污水处理厂（STP）是本案例研究的基础。基本前提是，STP 中发电本身就有利于巴西卫生部门的公司，从而降低处理过程的成本。在过程结束时会在两个层面上获得收益，即：（i）经济方面，通过燃烧沼气产生的电力与支出相比增加了 165%；（ii）能源方面，通过添加一种新的可持续和可储存的能源，相当于 SP 州供应的天然气的 4%和沼气燃烧产生的电力与电力消耗相比的 0.5%。总之，与 STP 中的沼气相关的发电潜力能够满足其国内需求，并将剩余电力出口到该州和国家经济的其他部门。
