Abstract

Pembangkit Listrik Tenaga Air (PLTA) Cisokan merupakan PLTA dengan jenis Pumped Storage (PS) yang direncanakan beroperasi pertama di Indonesia dengan kapasitas sebesar 4x 260 MW pada tahun 2029. Berdasarkan dokumen Studi Kelayakan PT. PLN (Persero) PLTA Cisokan direncanakan untuk beroperasi selama 8 jam untuk memompa air (pumping) dan beroperasi selama 6 jam untuk membangkitkan listrik (generating). Pola Operasi tersebut belum optimal untuk filosofis pengoperasian pembangkit energy storage sebagai energy regulation, karena belum dapat meminimalkan fluktuasi beban, terutama untuk pengisian lembah (valley filling) dan pemangkasan puncak (peak shaving) pada profil beban harian. Diperlukan optimalisasi untuk pola operasi PLTA Cisokan PS sebagai energy regulation di sistem tenaga listrik Interkoneksi Jawa – Madura – Bali pada profil beban harian di sistem 500 kV. Optimalisasi dilakukan dengan meminimalkan variance dari Pres sehingga beban tidak memiliki fluktuasi yang tinggi. Lebih lanjut Optimalisasi dengan prinsip Unit Commitment (UC) dan Economic Dispatch (ED) dilakukan untuk meminimalkan komponen C pada BPP PLTA Cisokan PS. Setelah melakukan optimalisasi penjadwalan, didapatkan bahwa variance dari Pres sesudah dilakukan optimalisasi mengalami penurunan, Capacity Factor (CF) mengalami peningkatan dari keadaan awal bernilai 25% menjadi 27.27%. Komponen A,B dan C pada BPP Cisokan mengalami penurunan, sehingga BPP yang bernilai awal dapat direduksi menjadi Rp. 1095.57/kWh, dengan nilai pengurangan sebesar 12.75 % terhadap BPP awal.

Abstract

Currently, Indonesia is still using fossil fuel power plants. The high use of fossil fuels will harm the environment, therefore to reduce the use of fossil fuels, it is necessary to develop renewable energy power plants, one of which is a solar photovoltaic power plant. This study discusses the economic analysis of planning a soalr photovoltaic power plant at the Taman Melati Depok Apartment which is connected to the PLN network with the PVsyst software. This PLTS plan will be built on the roof of the apartment using an area of 437 m2 with generated power of 90,400 Wp. Using solar modules with a capacity of 565 Wp as many as 160 modules. This PLTS can generate electricity per year 116600 kWh/year. The Cost of Energy (COE) for this PLTS is Rp.735.39/kWh. Economic analysis uses Net Present Value (NPV), Profitability Index (PI), and Discounted Payback Period (DPP) to determine whether this PLTS is feasible or not. Based on the calculation result, the NPV value is Rp. 608,793,939.29, while the PI value is 1.587 and the DPP value is around 12 years and 9 months, which is faster than the project age, which is 30 years. Thus the investment in the Taman Melati Apartment PLTS project is feasible to continue.

Abstract

Jakarta's dense population creates problems with the high daily waste production, which reaches 7,500 tons. On the other hand, the open dumping method in the final waste treatment creates another problem in the form of greenhouse gas emissions. The regional government also issued a policy to reduce greenhouse gas emissions to achieve net zero emission by 2050. The solution that then emerged for the two problems above was to convert waste into electrical energy through incineration technology. This study aims to conduct an economic analysis in the context of implementing incineration technology. The results showed that the minimum capacity for economic feasibility was 8 MW with an LCoE of IDR 2,578.32/kWh, 429 tonnes of waste per day, an IRR of 8.63%, and an NPV of IDR 115,038,835,638.12 at an investment value of IDR 505.877.074.317

Abstract

To encourage national economic growth, efforts are made to maintain electricity availability in Indonesia. Until now, the need for electrical energy in Indonesia is still supplied by fossil fuel power plants, especially Steam Power Plants and Gas Steam Power Plants. One of the negative impacts arising from electricity generation activities is air pollution. Air pollution is produced in the form of waste gases such as PM10, SO2, NO2, and these gases causes global warming and impact of human health. In this study, the magnitude of the negative impact calculated based on the impact on public health, which will then be limited to economic value (cost of externalities). Cost of externalities are conditions when the effect of the production of goods or services imposes costs or benefits on other parties, and these costs are not reflected in the price charged for the goods or services produced. The estimation of public health impacts and externality costs calculated in this study comes from power plants operating at the Muara Karang Generation Unit using Robust Uniform World Model (RUWM). The research results show that the amount of health and externality costs obtained for each power plant are different because each power plant has different operating conditions. In PLTGU Block 1, the resulting externality cost was 18,51 cents USD/kWh, PLTGU Block 2 was 3,05 cents USD/kWh, and PLTGU Block 3 was 1,75 cents USD/kWh. The two Unit of PLTU Muara Karang generate different externality costs, namely 1,52 cents USD/kWh for PLTU Unit 4 and PLTU Unit 5 of 1,10 cents USD/kWh.
