2026 is incomplete. Within a successfully fetched ten-year window, omitted years mean zero. Years beyond a saved observation’s window remain unknown (—). Older citations are excluded, so this chart’s sum may differ from the OpenAlex lifetime total. The date above belongs to this annual history; an unsuccessful refresh keeps the previous observation.
Abstract
This study examines the economics and the cost per kWh (IDR/kWh) of household gas-fired power generation coupled with a renewable energy source, namely a Solar Power Plant (PLTS). The calculations in this research employ individual economic assessments for a standalone PLN system, a natural gas generator set, a solar power plant (PLTS), and a hybrid combination of a natural gas generator set and PLTS. The analysis focuses on the economic aspects of the household electricity system using the Levelized Cost of Energy (LCOE), Life Cycle Cost (LCC), and Cost-Benefit Analysis (CBA) methods. The study is conducted by evaluating the electrical economics and determining the resulting IDR/kWh cost generated by the standalone PLN system, the natural gas generator set, the PLTS, and the hybrid system combining the natural gas generator set with PLTS. The research findings are expected to contribute to the development of a more efficient and sustainable distributed energy system.
