Taiwan's 2050 Net-Zero Transformation Strategy Planning

• In March 2022, Taiwan officially announced the “Taiwan's 2050 Net Zero Emissions Pathway and Strategy". The 2050 Net Zero Pathway will be based on four major transformations and two major governance foundations, supplemented by 12 key strategies, including wind power, photovoltaic, hydrogen energy, power systems and energy storage, to implement the net zero transformation Goal.

• According to the announcement of the Ministry of Economic Affairs on 28 December 2022, the new energy ratio in 2030 (532), the proportion of gas remains at 50%, the proportion of green energy is increased to 30%, and coal consumption is 20%.

• In 2050, the demand for electricity will increase by more than 50%, and the planned power distribution ratio set by the government is 60-70% for renewable energy, 20-27% for thermal power, and 9-12% for hydrogen. There is great room for growth of renewable energy in the future.

New “Pilot Program of ESS Demand Response to Renewable Energy Heavy Electricity User”

• ✓ According to the latest Taipower 2023/06/21 announcement, the new “Pilot Program of ESS Demand Demand Response for Voluntary Users of Renewable Energy” program allows users to choose to participate in Taipower‘s dispatching, and to receive preferential electricity prices during a certain period of time to assist in system scheduling adjustments. The implement the pilot program which will be officially launched first in 2024 .

4 option choose 1

Formula

Installation of

renewable energy Capacity of obligatory device = capacity of generation obligatory contract x 10% equipment

Purchase of Annual purchase quota = obligatory installation capacity x annual quantity of electricity sales renewable energy per kW for the selected category of renewable power and energy certificates Capacity setting = capacity of the Setting up energy obligatory device x minimum power supply storage equipment for 2 hours

Annual payment = obligatory installation monetary capacity x 2500 kWh/kw x $4 dollars / kWh substitution (the rate of monetary substitution)

Trial run period: 1 July 2023 to 31 December 2023

The energy storage equipment installed by Heavy Electricity User will have a fixed discharge of 2 hours from 6: 00 p.m. to 8: 00 p.m. per day from Monday to Friday (excluding the off-peak day), and is limited to once a day. The following 2 types of electricity bills can be selected:

Volunteer Hour Type Progressive Type Set the number of hours of If no hours of obligation are set, a obligation (400 hours), and progressive reduction of NT $1 ~ provide a reduction of electricity 5 is made based on the hours of fee of NT $10 per kWh in excess discharge. of the number of hours of obligation. * The deduction is NT $1 per hour for 150 hours, NT $2 per * Volunteer discharge: Volunteer hour for 151 to 400 hours, and capacity x volunteer hours (400 NT $5 per hour for more than 401 hours a year) hours.
