Investigating the Impact of Carbon Tax to Power Generation in Java-Bali System by Applying Optimization Technique
Java-Bali power system dominates the national installed capacity and will contribute to about 76% of the national CO2 emissions from the electricity sector in the future. Thus, minimizing CO2 emission from the Java-Bali system can help Indonesia to reduce the national CO2 emissions level. We apply optimization approach to investigate this problem by including carbon tax into the cost function. We analyzed data based on electricity generating system in 2008. In general the optimization showed that diesel and gas turbine is not needed in the power plant system. Further, the simulation showed that if Indonesia adopted carbon tax by US$56/ton CO2 - USD 86/tCO2; it will lead to three major changing. First, carbon tax will increase the cost of power plant or equivalently increase tax revenue to about 2.1% of GDP in a year. Second, combine cycle has important role to offset decreasing output in steam power plant. Finally, by implementing carbon tax, daily CO2 can decrease by 77,586 ton per day. By applying sensitivity analysis, we also found a structural break in marginal cost when carbon tax is higher than US$ 50/tCO2. There are some weaknesses from this study such as not use strong assumption for availability factor and generating costs. This study proposed that government needs to optimize utilization of combine cycle power plan to offset steam power and implement carbon tax above US$ 50/ ton CO2, to reduce CO2 emissions significantly.
Post-kyoto International Climate Policy
The Harvard Project on International Climate Agreements is a global, multi-disciplinary effort intended to help identify the key design elements of a scientifically sound, economically rational, and politically pragmatic post-2012 international policy architecture for addressing the threat of climate change. It has commissioned leading scholars to examine a uniquely wide range of core issues that must be addressed if the world is to reach an effective agreement on a successor regime to the Kyoto Protocol. The purpose of the project is not to become an advocate for any single policy but to present the best possible information and analysis on the full range of options concerning mitigation, adaptation, technology, and finance. The detailed findings of the Harvard Project are reported in this volume, which contains twenty-seven specially commissioned chapters. A companion volume summarizing the main findings of this research is published separately as Post-Kyoto International Climate Policy: Summary for Policymakers.
SCIENCE AND EMPIRICISM IN PILE FOUNDATION DESIGN
Scientific approaches to pile design have advanced enormously in recent decades and yet, still, the most fundamental aspect of pile design—that of estimating the axial capacity—relies heavily upon ...
