Increased consumption of electrical energy must be accompanied by the provision of sufficient electrical energy. The limitations of fossil energy make it necessary to increase to utilize new renewable energy sources (EBT). One of the potential sources of NRE is solar energy with an average daily insolation of 4.8 kWh / m2. Floating solar power plant is one type of solar PV power plant installation with the best efficiency. The floating solar power plant design in this study is located on Jatiluhur Dam with an on-grid system. This research focuses on detailed surveys, Detail Engineering Design (DED) and power generation costs. Detailed survey and site feasibility analysis based on site conditions and accessibility, climate and weather, soil and water conditions, shadow and soiling conditions and water bathymetric conditions. Mathematical calculations are performed to assist in the creation of DED. While the selection of components is based on needs and comes from tier-1. The study also considers existing regulations and financial analysis to derive the cost of generating the system. The design of 1 MW floating solar power plant consists of 5 main components. Solar panels come from Jinko Solar 550 Wp as many as 2160 which are arranged in series of 18 solar panels and a total of 120 strings. The inverter used comes from Growatt MAX 100KTL3-X LV 100 kW. DC cable using JJ LAPP ÖLFLEX® SOLAR XLWP 1Cx6 mm2 solar cable, AC cable between inverter and AC combiner box using NYY cable 4Cx95mm2 and AC cable between AC combiner box and interconnection point using NYY cable 1Cx240mm2. The floater, mounting and anchoring system components come from Sungrow. The performance of the system design is quite good with a maximum efficiency of 19.713%, a capacity factor of 19.42%, and a performance ratio of 85.32%. Meanwhile, the range of LCOE values for floating solar power plants is USD 0.047 - USD 0.068 per kWh, or in Indonesian Rupiah, Rp 709 - Rp 1013 per kWh
