Abstract— Most of the power plants use fossil energy sources, while fossil energy has several undesirable effects. To overcome this, it is necessary to develop in electricity that is by using renewable energy as a source of electrical energy. Some examples of electrical renewable energy sources used are solar energy and wind energy. Renewable energy as electricity generation can be developed using a microgrid concept, generation with more than one power plant. The combination of different types of power plants is often called a hybrid power plant. One example is a hybrid power plant with a smart microgrid network system at the Department of Electrical Engineering, Faculty of Engineering, Udayana University, which has been operating since 2017, which is a collaboration between Udayana University and the Ministry of Energy and Mineral Resources (ESDM). This smart microgrid requires a study of the energy supply system of the power generation in order to know its performance to serve the DH building load. The study will analyze the data in October 2018. Research results show that smart microgrids cannot fully meet the electricity load in October 2018. The electrical energy load of 4330 kWh DH building is supplied by PLTS 333,383 kWh, PLTB 121.07 kWh, and supply of 803.57 batteries. kWh The shortage of electrical energy from the microgrid system is supplied by PLN by 1591.7 kWh and when overproduction, PLN can get energy from the 541 kWh microgrid. Battery charging energy is 1894.38 kWh. The use of renewable energy in the DH building reached 63.24%. Keywords— Microgrid, PLTS, PLTB, Battery

Electrical energy is one concerning lives of the people, then provision must be able to ensure the availability of a sufficient number, reasonable prices and good quality. Until now, the use of fossil fuels is still quite high as a primary energy source that is utilized in the process of generating electricity. It has an impact on climate change so that Greenhouse Gases (GHG) arise. The composition of energy use at the end of the projection (2030) uses LEAP software Household consists of the sector amounted to 5.865,1 GWh, Industrial sector of 490.380,6 GWh, Public (Commercial) sector of 3.547,5 GWh, and from Transportation sector as big as 7.220.937,8 BoE. The projection of GHG emissions using LEAP software shows that emissions in 2030 for the Household sector amounted to 8.9115 million tCO2eq, the Industrial sector amounted to 1212.3964 million tCO2eq, the Transportation sector amounted to 26.2161 million tCO2eq, and when the generation of electricity was 33,0955 million tCO2eq. So the total GHG emissions generated are 1,280,6196 million tCO2eq, this amount is an accumulated increase from 2015 of 61.4533 million tCO2eq. To suppress the amount of increase of that size, efforts need to be made such as promoting the use of environmentally friendly energy. Reduce the use of private vehicles and switch to public transportation. The government must also support by providing environmentally friendly mass transportation facilities.

Abstract - This paper introduces a redesign of Micro Hydro Power Plant (MHPP) in Banjar Dinas Mekar Sari, Panji Village, District of Sukasada, Buleleng Regency, Bali. The MHPP has been operated since 1980 by utilizing waterflow of Tukad Pasut River. Early investigation indicated that there is a reduced production capacity of the MHPP due to lack of maintenance. In addition, the initial design of the MHPP has not adopted the advanced power control systems, resulting in inefficient power production. The introduced design of the new MHPP utilizes a crossflow turbine to accommodate a waterflow rate of 1,32 m3/s and with an effective head of 16 m. The turbine mechanical energy is coupled to a generator by means of a belt coupling system, with a belt length of 3099 mm. The pulley diameter is 750 mm for the turbine side, and it is 149 mm for the generator side. The generator capacity is 185 kVA, 50 Hz, 230/400 V, 1500 rpm, and with an efficiency of 94%. The Electronic Load Controller has a capacity of 180 kW, with 6 ballast loads of 30 kW. The connection from the generator to the transformer uses the NYFGbY underground cable of 4 × 95 mm2, with a length of 69 m. The transformer is a step-up and step-down type with a capacity of 250 kVA.

Around the world the deregulation of the electricity business sector has changed from a centralized and integrated into a segmented industry based on the competence of the business people. The new form of trade with free access to transmission and distribution channels has encouraged a competitive trade between consumers and plant owners. In such environments, the transmission network is considered a key factor in the electricity market. Utilization of other companies' transmission to distribute electric power is commonly known as PBJT or Wheeling Transaction. The term PBJT in Indonesia is known as Joint Transmission Network Usage. There are several methods used to calculate transmission lease cost in this paper are used two cost allocation calculations that allow to apply to Bali electricity system that is, Postage-Stamp Rate method, MW-mile method. In this paper, we will apply the Postage Stamp Rate and MW-mile method of Wheeling Transaction in order to obtain the calculation of transmission lease cost acceptable by both parties. Keywords- Transmission, PBJT, Wheeling Transaction, Postage-Stamp Rate, MW-mile

Lighting is one of the primary needs of humans wherever they are, because the presence of lighting will greatly help human activities and productivity. The more the number of people the need for lighting also increases. This means that it is directly proportional to electricity needs. In this study the calculation of the savings of LED lights was carried out using the Life Cycle Cost (LCC) method in BRI Regional Office buildings in Denpasar. As a result, the replacement cost for the Philips brand LED costs Rp.145,093,000.00. Energy saving obtained is equal to 11,309.49 kWh per month, so the bill savings obtained with the electricity tariff per kWH Rp.1,117.00 is Rp.12,632,700.00 every month. The operational cost of LED lights was originally Rp.132,172,421.00 will experience a gradation of inflation rate of 4.2% so that during the life time of the lamp (4 years) it will be a total of Rp.562,939,535.08. The total LED LCC is Rp.708,032,535.08 with a period of 4 (four) years, while the total existing LCC lights are Rp.628,293,771.91 with a period of 2 (two) years. The economic feasibility study using the PBP method shows results that are feasible to be accepted, but for the NPV method, the IRR and PI show results that have not been properly received. Based on calculations using the NPV method and PI, it can be seen that to be a feasible outcome, the initial cost is a maximum of Rp.108,468,555.35.
