Solutions For Growing the Power Factor Prevent A Reactive Electricity Tariff And Decrease Warmth On Installation With Bank Capacitors

PT. Intan Ustrix that's placed at Jl. Raya Roomo No.425, Sekarsore, Roomo, Kec. Manyar, Kabupaten Gresik Indonesia is a company engaged in the paper and cardboard business, and has many machines used in the manufacturing process. The load of the induction motor will make the cost lower, thereby increasing the current cost through the device inside the carton production unit. Fixing the cost of cos is a great way to solve this problem. In this case, it is very important to install a capacitor bank to recover the charge. By installing a capacitor bank will affect the overall performance of the motor used. The cause of this research is the increasing cost of boarding at the cardboard production unit of PT. Intan Ustrix. As an evaluation, capacitor banks are installed on the H200, AFG, 6PA, FM, and 6PS buses so that low cos costs can be increased. The final result of this charge shows that increasing the cos cost at full load of 325 KW from 0.716 to 0.872 can reduce the actual power cost (S) from 396 KVA to 329 KVA, which can maintain 65 KVA and today's decrease (I) from 498 A to 410 A, the lower the current consumption price of the motor used can increase the resistance of the device to the carton production unit.

Analyzing German consumers’ willingness to pay for green electricity tariff attributes: a discrete choice experiment

Background In order to achieve an environmentally friendly and sustainable energy supply, it is necessary that this goal is supported by society. In different countries worldwide it has been shown that one way consumers want to support the energy transition is by switching to green electricity. However, few people make the leap from their intention to a buying decision. This study explores parameters that influence whether German consumers would hypothetically decide to switch to a green electricity tariff. Methods A quota-representative online survey including a discrete choice experiment with 371 German private households was conducted in 2016. For the econometric analysis, a generalized multinomial logit model in willingness-to-pay space was employed, enabling the estimation of WTP values to be as realistic as possible. Results The results show that consumers’ decision whether or not to make the switch to green energy is mainly influenced by the source of green energy, whether a person can outsource the switching process, and a person’s attitude towards the renewable energy sources levy that currently exist in Germany. Conclusions The findings indicate that politics should focus on supporting wind and solar energy as German consumers prefer these sources over biogas. As the results suggest, the EEG levy is a reason why consumers have lower WTP for switching to a green tariff. Therefore, a switching bonus with a specifically “framed” bonus in the amount of the current EEG levy could be a promising strategy for the increase of green energy tariff acceptance. Furthermore, attention should be given to psychological and behavioral aspects, as the results indicate that these factors influence the consumer’s choice for a green electricity tariff.

The Constraint of the Eco-Friendly Rooftop PV System Implementation Based on the Techno-economic and Regulatory Impact Analysis: Case Study of The Ontowiryo Mosque in Purworejo, Central Java, Indonesia

Background: The government is optimistic that Indonesia is able to be energy independent because Indonesia has a variety of energy sources that can be utilized for the benefit of the nation and state, both fossil and non-fossil energy sources, including solar energy through solar power system. The solar power system or photovoltaic system is an eco-friendly option usually applied to meet the need for energy due to its lower carbon footprint when compared to fossil-fueled power plants. This research was, therefore, used to conduct a techno-economic and regulatory impact analysis on a rooftop photovoltaic system installed in a mosque in Purworejo, Indonesia under a net metering mechanism. Result: The installation was aimed at reducing entire carbon emission from the annual energy usage which is an equivalent of 4 tons of carbon dioxide. The research shows that the economic feasibility of the photovoltaic systems, measured by the Net Present Value (NPV) of the electricity bill saving are negative values for all the configurations based on the type and number of panels. This low financial attractiveness was observed to be due to several unsupportive regulations such as subsidized electricity tariff, minimum grid electricity usage limit, and less-rewarding net metering scheme. The research also suggests that the abolishment of the minimum usage limit was discovered to have incurred the greatest increase of NPV to the photovoltaic system designed to entirely supply the load demand while the implementation of a higher electricity tariff caused the highest increase of NPV for the photovoltaic systems with partial supply scenario. Conclusion: Finally, it is financially unfeasible to install a photovoltaic system on the mosque rooftop at the current electricity tariff, costs of components, and regulations implemented concerning the adoption of the system. As a constraint, the power regulation in Indonesia should be reviewed significantly to support any buildings of worship to develop their opportunities for managing energy systems independently. The potential implication is that they would be able to contribute their social economic role in supporting their really crucial community daily life energy. This approach is in line with the government policy and strengthening the sustainable development goals.
