The Role of Nuclear Power and Other Energy Options in Competitive Electricity Market Study Using Message Model

THE ROLE OF NUCLEAR POWER AND OTHER ENERGY OPTIONS IN COMPETITIVE ELECTRICITY MARKET STUDY USING MESSAGE MODEL. The electricity demand in Indonesia is very high due to the National Economic Development based on industrialization and supported by a strong agriculture base. It can be noted that in the last five years, the annual electricity growth rate has been reaching around 15% per annum. Though during the economic crisis the electricity demand have time to reduction. Start early 2000s the economic growth in Indonesia will gradually increase. As a consequence, the electricity growth rate also increase in the next coming decades. MESSAGE (Model for Energy Supply Strategy Alternatives and their General Environmental Impacts) is a model designed for the optimization of energy system (i.e. energy supplies and utilization). The goal of this study is to support the national planning and decision making process in the energy and electricity sector in Indonesia with regard to the economic, health, environmental and safety aspects. The objective of this study is to analyse the role of Nuclear Power Plant in the whole energy systems by introducing the new electricity regulation and structure in the market. Seen that Nuclear Power Plant will be enter the Java Bali system in the period between 2015-2020. and will dominate the addition of capacities by the end period of study (year 2020-2025). Nuclear energy has very important long term roles in the energy scenario and it is possible to do the market competitiive when the Multi buyer Multi Seller (MBMS) will be done in the system electricity in Indonesia (the government has changed the target of MBMS realization into 2007)

Perhitungan Biaya Eksternalitas Pltgu Gas Muara Karang

PERHITUNGAN BIAYA EKSTERNALITAS PLTGU GAS MUARA KARANG. Salah satu sasaran dari studi "Comprehensive Assessment of Different Energy Sources for Electricity Generation in Indonesia" adalah perhitungan biaya eksternalitas dengan menggunakan program Simpacts. Sasaran studi ini adalah mendukung perencanaan dan proses pengambilan keputusan energi dan listrik nasional dengan mempertimbangkan tekno-ekonomi, sosial, bijaksanaan, dan lingkungan. Salah satu pembangkit yang menjadi perhatian adalah PLTGU Muara Karang berbahan bakar gas dengan daya keluaran 500 MWe, yang berada di wilayah bagian utara Jakarta. Secara geografis wilayah ini sangat padat dengan penduduk dan di sekitarnya merupakan salah satu pusat bisnis dan industri di Indonesia. Hasil perhitungan menunjukkan besar dampak kesehatan yang terjadi sebanyak 51.400 kasus tiap tahun dengan 86,05% kasus yang terjadi adalah gangguan pernapasan tingkat rendah baik orang dewasa maupun anak- anak oleh polutan nitrat dan biaya kesehatan total yang dibebankan sebesar 1.830.000 US.S dengan 78,85% dari polutan nitrat dan 21,15% dari polutan N02. Biaya Eksternalitas yang diakibatkan oleh PLTGU Gas Muara karang selama tahun 2000 diperoleh sebesar 0,11 cent per kWh per tahun (berdasarkan data pada tahun 2000)

Low-cost smart solutions for daylight and electric lighting integration in historical buildings

Research have shown that the correct integration of daylight and electric lighting reduces the energy use in buildings, while improving visual comfort. Smart shading systems, especially those electrically controlled, play an important role to control solar radiation. Similarly, smart and dimmable/tunable lighting can help to adjust the artificial light to the real users' needs. This paper presents preliminary results of an ongoing living lab study investigating how artificial lighting systems can be integrated with shading systems, placing human comfort at the heart of the study and yet saving energy. A manually controlled, commercial and low-cost smart system integrating two motorized shading devices and six dimmable LED luminaires with a different selection of CCT were installed in a private office in a historical building. Indoor and outdoor lighting conditions and energy consumption associated to the lighting system are constantly monitored to assess how the people use shading and lighting upon varying the boundary conditions.. Preliminary results highlight that users prefer to maximise daylight on the work plane as well as they generally use both shading and electric lighting systems in response to boundary conditions that cause serious discomfort

Immersive virtual reality as a tool for lighting design: Applications and opportunities

Immersive virtual reality offers a wide range of applications. Immersive virtual reality in particular can play an important role in lighting design, thanks to its ability to allow a quick assessment between different design choices based on spaces, colours and light. However, immersive virtual reality has to guarantee a correct reproduction of light behaviour from photometric and visual points of view, in order to be effectively used for lighting analysis. This paper presents a literature review aimed to analyse the activities of the research groups operating in this field that have addressed, with different approaches and points of view, the issue of iVR applications in the reproduction of environments illuminated by either daylight or electric lighting, as well as a combination of them

Daylighting Contribution for Energy Saving in a Historical Building

AbstractThe purpose of this study is assessing the reliability of the software DIALux 4.12 for daylighting design, comparing experimental data with simulation results; the comparison was performed for an office.The daylight illuminance distribution inside the room, the external zenith luminance and the external horizontal diffuse illuminance were measured during the weeks from January 19th to February 20th; the data gathered were further reduced to match conditions related to the CIE sky type #12 (CIE Standard Clear Sky, low luminance turbidity) and finally the comparison was carried in terms of daylight illuminance distribution and relative percentage error

Energy Performances of Tensile Material in Building Renovation in the Nordic Region

Tensile materials are increasingly used in the building envelope as second-skin systems, despite a lack of investigation on their effects. In this work, a second-skin system integrating a tensile material as an outer layer has been adopted in the retrofit analysis of two of the most common building typologies in the Norwegian context. The simulations were carried out by implementing a custom control logic for the system, considering the outdoor air temperature and the global vertical irradiation on the façades. The proposed retrofit solution allowed for a primary energy saving of about 35%.publishedVersio
