Project Summary / Description:

Taoyuan City is the major manufacture center in Taiwan. The annual output value also ranks top 1 in Taiwan. However, the energy usage of Taoyuan is comparatively higher than other cities. The amount of electricity usage accumulates for 13.6% of the national electricity usage. How to make energy consumption and production sustainable is an crucial issue for Taoyuan. Since Taoyuan was upgraded as a special municipality in 2014, in order to accelerate deployment of renewable energy, the city government has been integrating administrative resources, researching on the potential to develop renewable energy and launching diversified renewable energy promotion initiatives.

Impact on Underrepresented Groups:

Among the renewable energy promotion initiatives, one of them was to build independent disaster response energy systems in remote areas. Through smart energy systems, the predicament of not being able to reach out when natural disasters occur, so-called island effect, could be prevented. We started evaluating in 2018 and the systems were planned to be equipped with functions of energy generation, storage and saving. 

By the end of 2019, we had built one independent disaster response energy system in Kuihui Village in Fuxing District, and another one in Sanhe Community in Longtan District. In Kuihui Village, a 5kW fuel cell and 10kWh energy storage equipment were set up at the village office. Equipped with the uninterruptible power system, it can provide electricity for more than 72 hours. 

In Sanhe Community, a 5kW fuel cell and 18kWh storage equipment were set up too, supplying electricity for more than 72hours. Furthermore, a renewable energy system with 5.4kW photovoltaic and 6kW wind power generation capacity, and 5 wind-solar hybrid power street lights were installed. According to statistics, 2,896 kWh of electricity was generated between January and September in 2020, around 20% of electricity usage of Sanhe Community.
