Sistem pembangkit listrik tenaga hibrida (PLT Hibrid) digunaka untuk mengurangi penggunaan energi fosil dan memanfaatan potensi energi baru terbarukan (EBT), terutama di lokasi terpencil. SPLTH memanfaatkan EBT sebagai sumber energi utama yang dikombinasikan dengan generator mesin diesel sebagai sumber energi cadangan. EBT berasal dari energi matahari dan energi angin di lokasi setempat. Pulau Pusong terletak di Kabupaten Langsa, Provinsi Nangroe Aceh Darussalam (NAD) merupakan daerah terisolir yang menggunakan unit genset. Tujuan dari penelitian ini adalah untuk mengidentifikasi potensi sumber energi terbarukan (angin dan matahari) dan mengembangkan desain serta analisis kelayakan ekonomi SPH di wilayah tersebut. Perancangan & analisis kelayakan PLT Hibrid dilakukan dengan menggunakan simulasi Hybrid Optimization Model of Electric Renewables (HOMER Energy). Sistem ini merupakan kombinasi dari Wind/PV//Diesel, baterai, DC/DC converter, dan DC/AC inverter. Hasil simulasi menunjukkan konfigurasi optimal adalah PV 520 kW, Inverter PV 500 kW, 2.7012 unit baterai, 100 kW diesel generator dan 125 kW inverter bi-directional. Konfigurasi tersebut memiliki nilai biaya energi sebesar 0,125 $/kWh dan Total Biaya Bersih Sekarang sebesar 0,973 Juta $. Konfigurasi ini dapat menekan penggunaan Bahan Bakar Minyak sebesar 94%. Simulasi sensitivitas menunjukkan bahwa nilai COE paling dipengaruhi oleh biaya PV, dan radiasi matahari.
Most power plants, particularly those that burn fossil fuels such as coal, oil, and gas, create CO2, a greenhouse gas that contributes to climate change. By 2060, the Indonesian government has committed to reach net zero emissions. With the lowest CO2 emissions, nuclear power plants are dependable sources of energy. Small modular reactors (SMRs) are a particular kind of nuclear power plant that has the potential to be Indonesia’s first commercial nuclear power plant because of their small size, low capacity, uncomplicated design, and modular characteristics. The purpose of this study is to examine the economics and technological feasibility of SMRs. In this analysis, the levelized cost of electricity (LCOE) comparative method and the technology readiness level (TRL) approach are both applied. The SMRs with a minimum TRL value of 7 were CAREM-25 (TRL7), KLT-40S (TRL8), and HTR-PM (TRL 8), according to the results of this research. Although CAREM-25 and KLT-40S are still in the demonstration stage and have not yet entered the market, their LCOE estimates are greater than 0.07 USD/kWh with a 5% discount rate. Whereas CAREM 100 MW is an economy scale from CAREM-25 and VBER 300 MW is a commercial size from KLT-40S, HTR-PM is already an economy scale. With discount rates between 5% and 10%, the LCOE values of HTR-PM, CAREM 100 MW, and VBER 300 MW range from 0.06 USD to 0.12 USD per kWh. Other than hydropower and coal-fired power plants, these LCOE figures can compete with the local LCOE in Indonesia and the LCOE of a variety of other types of power plants.
T he Republic of Indonesia is one of the largest producers of crude palm oil (CPO) in the world along with Malaysia [1]. In addition, Indonesia is an oil importing country. To reduce oil imports, the Minister of Energy and Mineral Resources (MEMR) issued a decree No. 25 of 2013 concerning changes to Ministerial Regulation No. 32 of 2008 concerning Provision, Use and Trading of Biofuel as Alternative Energy. According to the Ministerial Decree, the use of biodiesel in the electricity sector is targeted at 7.
<p align="justify">enewable energy (RE) power plants can reduce the use of fossil fuel power plants that damage the environment related to CO2 emissions. Solar power centers and wind/wind power plants (PLTB) have intermittent characteristics related to their performance which is strongly influenced by environmental conditions such as fluctuations in solar radiation & wind speed. This creates problems in the stability & reliability of the electricity system so that its utilization is not optimal. Pumped storage hydropower (PSH) is a renewable energy-based technology that can store excess energy production in the electricity system at low load conditions to be distributed when the system is in peak load conditions. This study aims to determine the use of PSH concerning increasing the penetration of RE generators in the electricity system. Pastel & SWOT (Strength Weakness Opportunity Threat) analysis methods were used in this study. From the results of the discussion & discussion, it was found that PSH technology can support the penetration of RE power plants in Indonesia, especially PLTB & PLTS because it can eliminate the intermittency nature of these plants in the electricity system. In addition, PSH is also a mature energy storage medium on a large & economical scale, making it suitable for application in large & complex electrical systems. The strength of PSH is its mature technology, especially from the aspect of its large and economical capacity. The weakness of PSH is related to its utilization depending on the location due to the need for the area to have sufficient water potential with hilly natural conditions (their elevation), and relatively large land. The opportunity offered by PSH is that Indonesia has many areas that have the potential to be developed into PSH. In addition, the use of PSH can reduce the cost of production and increase the penetration of PLTS & PLTB. The threat of PSH is the trend of decreasing storage costs & increasing battery performance.<em></em></p>
