Item Financial Analysis of Utility Scale Photovoltaic System with Battery Energy Storage System in Nepal(I.O.E. Pulchowk Campus, 2023-07) Shrestha, NarayanRenewable energy technologies (RETs) are essential for mitigating greenhouse gas emissions and transitioning to clean energy sources. Among various RETs, solar photovoltaic (PV) systems have gained attention as efficient and effective solutions. However, PV generation is intermittent and variable due to the diurnal cycle of solar geometry and weather conditions. Battery energy storage systems (BESS) integrated into PV systems can address these challenges by storing energy for later use. Nepal’s energy sector mainly depends on hydropower, which can be affected by natural and seasonal variations. To improve energy security and diversify its energy sources, the government has set goals to increase the use of solar and other renewable energy technologies in power generation. Nepal's favourable geography and abundant solar radiation make it suitable for deploying solar PV systems. Nepal receives an average of 3.6 to 6.2 kWh/m2/day of solar radiation and around 300 days of sunshine annually.Item Performance and Financial Analysis of Replacing LPG Stoves by Electric Rice Steamers for Rice Cooking: A case study of Nepali Army (Swayambhu Baroodkhana Karyalaya)(I.O.E. Pulchowk Campus, 2023-11) BATAJOO, MUKESHThe selection of appropriate energy sources for the cooking process directly influences individuals and the overall economy. In Nepal, energy sources for cooking are derived from biomass resources, imported fossil fuels, and a limited number of renewable energy sources. Given Nepal's commitment to achieving zero carbon emissions by 2045 and negative carbon emissions by 2050, prioritizing electricity for cooking over traditional biomass and fossil fuels is crucial for achieving energy self-reliance. This study explores the advantages of replacing LPG cooking stoves with electric rice steamers, focusing on the Nepali army (Swayambhu Baroodkhana Karyalaya) as a sample space. The study evaluates the benefits of cooking using electric rice steamers over LPG cooking stoves. Based on the experiment conducted, the specific energy cost and the thermal efficiency of the rice steamer are about three times more efficient than the LPG cooking stoves. The insulation test of the rice steamer showed that it took over 3 hours to cool down from 95°C to 77°C when the rice steamer door is closed. The survey found that the food taste was better and warmer. The relative cost-benefit analysis was conducted and found that electric rice steamers were 15.4 times more beneficial than the LPG stoves. It was found that presoaking rice for 30 minutes and refraining from immediately opening the steaming cabinet after powering off the Rice
