Measures to Promote Energy Prosumer in Photovoltaic Solar Energy

Abstract

In the process of implementing and trying various measures to achieve carbon neutrality around the world, Korea is also presenting various policies to advance to a low-carbon economy. Energy prosumer is a consumer who produces electricity directly and sells surplus electricity after consumption through an electric power company. Currently, advanced countries such as the U.S. and Germany are developing various business models beyond the initial energy prosumer model. However, in Korea, it is difficult for individuals to directly participate in the electricity market and buy and sell electricity due to policy limitations and complex reasons. In addition to these problems, low electricity bills and relatively high solar power prices are factors that hinder energy prosumers. Basically, in order for energy prosumers to be activated, the unit price of solar power must be lower than the unit price of electricity bill. In addition, an electricity market must be formed in which individuals can freely trade, and policies and legislation must be prepared to support them. If such a step is prepared to revitalize energy prosumers, energy self-sufficiency will be possible and a new energy industry will be established. Ultimately, decentralized resource systems such as smart grids are activated, enabling carbon neutrality. As the unit price of solar power in Korea has fallen and electricity bills are on the rise, energy prosumer’s prospects are positive. If the electricity bill system is implemented first through restructuring of the electricity industry, it will be possible to establish the energy prosumer system in Korea while trying to develop various energy prosumer business models and transaction methods.
