The Waste Power Plant is one of the power plants with a new renewable energy concept that utilizes waste as fuel. The processing of waste into electrical energy is carried out in two ways: the thermal conversion process and the biological conversion process to find the potential for waste that can be used as fuel to generate electricity. The analysis is needed, especially for Pangkalpinang, which currently has a lot of unprocessed waste. This research was conducted through calculations using several formulas that have been used in previous studies. From these results, the potential waste in 2015 is 97.25 tons/day and produces energy of 18548.10 MWh/year, and in 2020, it was about 186.57 tons/day and produced energy of 35547.18 MWh/year. The projection calculations are carried out to determine the potential for 2021 to 2030. Waste as much as 182523 tons/day in2021 can produce energy of as much as 34776.11 MWh/year. And in 2030, the amount of waste as much as 218132 tons/day can generate an energy potential of 41560.69 MWh/year.

The need for electrical energy in Indonesia continues to increase every year. In line with the increase in the electrification ratio to 100% in 2050, the demand for electrical energy is projected to reach 7 times, namely 1,611 TWh. To meet electricity needs, the government has created a 35 GW program, but one of the largest contributors to power generation fuel is coal with a share of 58% or around 50 GW which is estimated to be exhausted within the next 68 years. For this reason, innovations are needed in terms of fulfilling electrical energy by utilizing renewable energy potential, one of which is hydro energy, which is 45,379 MW from a total resource of 75,091 MW. Therefore, from this potential, innovations related to renewable energy have been created, namely the Hybrid Portable Underwater Turbine Hydro and Solar Energy hybrid power plant. This power plant uses an undersea current as a propulsion which is hybridized with solar power to increase the production of electrical energy. This power plant has the advantage that there is an Underwater turbine design that is resistant to underwater flow and a water flow direction to increase the work efficiency of the underwater turbine. From the test results, the portable Underwater turbine hydro produces 950 W in a day. Solar panels produce 65.6 Watts a day. The total hybrid that can be produced is 1.02 kW a day. In its implementation it can supply loads of up to 900 (VA) such as lamps, fans, TV, etc. This hybrid power plant can be a solution to help meet electricity needs in the area around Dusun Dongol, Sidoarjo through alternative electrical energy innovations.

For decades, Mauritania's economy has been fueled by thermal power.  As a developing economy, Mauritania's electricity demand has long been relatively low, though it has increased recently due to economic growth, urbanization, and industrial activities. The rapid growth in demand is making the country more dependent on oil and gas-based generation power plants, which a resultant drain on the national economy. However, Mauritania has abundant renewable energy potential. the deployment of renewable energy can be an alternative solution to reduce the dependence on fossil resources. In this paper, we have reviewed the situation of the power generation sector, the potential of renewable energy, the integration of renewable energy in Mauritania's energy mix and the mitigation potential. The installed capacity in 2018 is 415.5 MW. The percentage of thermal power plants is 59.8% and 40.2% of the integrated capacity is provided by renewable energy. In 2018, the total electric power generation was 1958.5 GWh, the contribution of renewable energy was 979.75 GWh. The IPCC 2006 methodology was used to estimate GHG emissions. The results showed that the integration of renewable energy into the country's energy mix reduced emissions by approximately 212.58 Gg CO2eq.

Photovoltaic systems or solar power plants  convert electromagnetic energy from sunlight into electrical energy. This renewable energy based power plant is one of the recommended solutions for electricity in remote rural areas where sunlight is abundant and fuel is difficult to obtain and relatively expensive. The Ministry of Energy and Mineral Resources has issued Ministerial Regulation regarding the use of the Roof Solar Power Plant  system by consumers of the Indonesian Electricity Company (PLN). It is hoped that with this regulation the solar panel business and industry can flourish. The method we use in this Community Service is the observation method. By making observations in the field accompanied by interviews with the surrounding population becomes our primary data source in determining the needs of the problems that occur. In Cilatak Village we found minimal of street lighting, and limited electricity supply, for this reason we strongly support programs for new and renewable energy for remote areas that are difficult to get electricity supply. Based on this, we created the Development of Public Street Lights with Solar Electricity in Cilatak Village, Ciomas District, Serang District, Banten, so that the problems of public road lighting can be overcome, and we educated the utilization and maintenance.

Abstract Introducing large amounts of electricity produced from variable renewable energy sources such as wind and solar decreases wholesale electricity price while increasing the volatility of the market. These conditions drive the need for peak-load power generation, while regulation requirements fuel the push for flexible power generation. The increase of variable renewable energy in the market share, along with falling natural gas prices, makes nuclear power plants less competitive. Thermal storage is being considered to increase the nuclear power plant revenue. Thermal storage increases the flexibility of the nuclear plant system without sacrificing its efficiency. There are multiple opportunities to increase the nuclear power plant revenue, including increased capacity payments, arbitrage, and ancillary services. An economic analysis was performed to investigate the revenue increase of the system with thermal storage. The investment cost was assessed, and net present value was evaluated for the considered scenarios. Two system designs were considered in the analysis: a thermal storage system using the existing power conversion infrastructure and an integrated design with thermal storage fully incorporated into the reactor system design. The preliminary analysis showed that introducing a thermal storage system is profitable for some scenarios considered. Profitability depends significantly on the storage size, output flexibility, share of variable renewable energy, and market characteristics.
