Sidik Boedoyo 3 Department of Energy Security, Faculty of Defense Management The Republic of Indonesia Defense University Bogor, Indonesia Abstract:- Coal energy is still dominantly used as fuel for power plants as a system for meeting the needs of electrical energy in Indonesia. At the end of 2021 the government issued a policy to limit coal exports with the aim of meeting coal needs for general electricity. The government predicts that by 2025 the need for electricity will reach 125 GW, and the government also issues policies with the aim of renewing energy having a role in 2025 by 5% and specifically for solar power plant contributing 800 MW. The method used is a literature study that is used to collect data relating to renewable energy policies, the potential for new and renewable energy in Indonesia, the potential of each province related to the use of solar energy, problems that still exist in the development of PV mini-grid, and analysis of solutions for development. next solar power plant. The potential for solar power plant development in Indonesia where solar energy has a potential of 207,898 MW in all parts of Indonesia, but in practice the use of solar energy is still minimal at 0.04%. The government has the responsibility in managing national energy for the availability of national energy, various policies and regulations are issued for the development of new and renewable energy, especially in the development of solar power plant. Several problems also still arise related to the development of PV mini- grid, especially in remote and outermost areas in Indonesia, such as the high cost of development and the lack of investors in new and renewable energy. The government should also strive to implement policies and regulations in order to achieve the target in the medium term of 2025 by providing flexible policies to investors and also on technical developments that need to be standardized for products.

INTRODUCTION Indonesia is one of the four largest coal producers in the world, with a total annual coal production capacity of more than 130 million tonnes [1]. According to PT. PLN's Electricity Supply Business Plan (RUPTL), Indonesia stores coal reserves of 38.80 billion tons in 2019 [2]. It is predicted that coal production in Indonesia in 2020 can reach a total of around 529 million tons. Of the total production, the percentage of coal exports reached 357 million tons (63%) which was mostly exported to meet demand in China and India [3]. The high level of production, coupled with the decline in demand caused by the Covid-19 pandemic virus in 2020 has depressed domestic commodity prices and prompted miners to lower their production targets [4]. At the end of 2021 the central government through the President of Indonesia issued letter number B- 1605/MB.05/DJB.B/2021 which is available to fulfill coal needs for general electricity [5]. This policy occurred because of the coal production crisis that occurred in Indonesia, this policy must also be complied with by entrepreneurs with a domestic market obligation (DMO) mechanism, companies that violate will receive strict sanctions. During the coal crisis that occurred in Indonesia, it was also caused by the high price of coal in the market, so mining companies chose to ship coal to PLN. The supply of electricity in Indonesia is predicted to reach around 125GW in 2025, so renewable energy resources are needed to support the supply of electricity. Renewable energy that can provide significant support is geothermal, biomass [6]. The Indonesian government has issued a National Economic Policy (KEN) with the aim of addressing the growing national electricity demand as a result of limited natural resources, namely fossil fuels. The role of electric energy as well as the government to manage energy from KEN has been planned for the development of power plants in 2025 which is estimated at around 5% of the total generating capacity in 2025, the report said. And this solar power plant is predicted to be able to produce 800 MW, with an annual growth rate of around 40 MW [7]. Solar power that is utilized today is one of the most promising energy resources in the 21st century [8]. A clean solar system can reduce CO2 emissions that can cause global warming, besides that solar systems can take advantage of unlimited solar power.
