Economic Feasibility Analysis of Building Seonam Biogas Combined Heat and Power Plant

Abstract

Recently, technology for energy recovery from waste has been increasing interest globally including the Korea. In Korea, we have interested in using biogas generated from the sewage treatment process. As one alternative, there are operating biogas combined heat and power plant. The generation amount of the Sewage Sludge are expected to grow in the future. For this reason, total processing cost of Sewage Sludge will increase. To solve this problem, it seems will be invested with the expansion of facilities that use biogas as energy. Therefore, quantitative information on such facilities is required. Thus, this study attempts to economic feasibility analysis for Seonam Biogas Combined Heat and Power Plant. Meanwhile, as the benefit items for economic feasibility analysis consider electricity supply benefit except for heat supply benefit. The average prices of electricity use were residence 123.69, commercial 130.46, and industry 102.59 won per kWh for the year 2015, In addition, the economic benefit are calculated to be residence 310.21, commercial 378.49, and industry 222.87 won per kWh. The results of economic

Design and Implementation of HMI-based Integrated Energy Usage–Monitoring System

“…Generally, CHP generation operates in two parts. The high temperature part is used as moving power, whereas the low temperature part is used as heat [2,7,8].…”

“…In Korea, a competition principle has been introduced into the electricity industry. As demand for power consumption sharply increases, a lot of attention is being paid to rationalization of energy use [1,2,7].…”
