Therefore, recently, a system mode of distributed power generation (DG) is suggested to enhance the resilience of the power supply system to maintain a steady supply of electricity in the face of disaster to quickly recover in short period of time. In addition of other features, there are benefits of increasing the use of renewable energy, minimizing the use of fossil fuel and reducing the overall cost of power production. Such distributed power generation system can provide companies with low-carbon, low-cost and resilient supply of power. Encouraged under the international policy of carbon reduction with decline in the cost of renewable energy, such as solar and wind power, there is an international trend of energy transformation underway and Taiwan, is no exception. The expansion of using renewable energy will face issue of integrating it with the traditional power grid system and thus, this is the advantage of a distributed power generation system. For any enterprises, a stable supply of power is essential. The amendment to the “Electricity Act” and the “Renewable Energy Development Act” passed in 2019, all aim at adopting policy for distributed power system and developing a decentralized power supply network. The amendment of the “Renewable Energy Development Act” further mentions the required installation of renewable power generation and storage facilities through purchase of certified equipment. It seems to be a necessity for companies in Taiwan to participate in the development of DG system. The objective of this study was to investigate the current status and reasons for enterprises in Taiwan to develop and use DG system through survey questionnaire, as well as any comments. Then, based on the research result, some recommendations could be proposed to the government and enterprises in terms of developing DG system. The method involved survey questionnaire to understand the current status of industry, including potential advantages, factors and challenges of using such DG system for enterprises. The survey would also compare the difference in corporate attribute and utilization factor among enterprises. The sample size of this study showed less than half of enterprises adopted DG system. Most used solar power and it was primarily due to the policy of “carbon reduction” reinforced by the government. The reasons for not using DG system included “insufficient support” and “lack of incentive”. In terms of potential advantages of using a DG system, “effective reduction of carbon emission” was the major reason, followed by “allowing more use of renewable energy” and “improving more reliable power supply”. The most common incentives were the “corporate social responsibility” and the “global trend of energy transformation”. However, there were challenges, such as “weather dependency of renewable energy” and “lack of complementary support and measure”, as the DG system is an emerging concept. The study discovered that the current corporate attribute was not related to the use of DG system. The response rate to the survey questionnaire in this study was not ideal, reflecting the enterprises’ unawareness of importance of DG system. Therefore, it is recommended that the government can encourage more high-energy consumption companies to understand or try it by promoting the advantages of such system. As for companies, they should actively participate in some non-governmental organizations or government-sponsored seminars to understand the system’s advantages and even refer to those with use of the DG system in their future plan; thereby, increasing the use of DG system in the power grid.
