➢ To produce more Green
  Energy ourselves
• Taiwan government carry out the Energy
  Transition of NULC, i.e. No Nuclear and
  Low Carbon. To fulfill the policy, Taipower
  has been taking several measures to
  enhance the utilization of green energy.
Although currently Taipower is the the
largest producer of green energy in Taiwan,

• We cannot keep the championship in
  the future without developing offshore
  power.
Now we have 2 projects in construction.

➢ To Strengthen the Grid and Friendly for Connection

  • As being the unique operator of power grid in Taiwan, Taipower is
    also obliged to make the grid-connection friendly.
 However, the challenge ahead is much more tough than ever to face the
 renewable energy rush-in situation. The government’s RE target is as following :

  ⚫     By 2025 : 27GW (PV 20GW, Wind 6.7GW and others)
  ⚫     By 2035 : 37GW (Offshore wind power increase 1GW every year
        to reach 10GW of accumulation.
  Taipower has to upgrade the present grid of 5GW scale of green power to that
  large scale still with good quality in 5 and 15 years. The smart grid plan is now in
  progress to fulfill this mission.
                                                                                         15

➢ Smart Dispatch Facing with Renewable Energy
➢ The intermittent characteristic of Renewable Energy is the
  biggest challenge to system operation in period of high
  penetration.
➢ If the Renewable Energy generation suddenly drops, the
  system frequency may drop consequently to trigger UFLS
  relays and affect the reliability of power supply.

Seek for cooperation from Major Private Developers

Technical Requirements for Offshore Wind New Players
I. Improve RE generation forecast
II. Improve the ability of voltage support
III. Improve the ability of frequency support
IV. Capabilities of Voltage/Frequency Ride Through
V. Regulations for the ramp rate needs to be enacted
However, the above-mentioned requirements will be discussed to reach a
common acceptance through the reviewing of Grid Code before execution.

                                                                         22
⚫ Taipower being the unique public power buyer and seller in
  Taiwan, to meet the green energy demand of customers is also
  our upmost goal of business.
⚫ Should Orsted want to sell the energy of her Changhua OWF
  to TSMC, Taipower will provide the wheeling service.
⚫ However, don’t forget Taipower is the largest green energy
  provider, our green energy is abundant, price-justified with
  good quality and lots of diversity. Please contact our Business
  Department for further information.

➢ Conclusion and Suggestion
 • Taiwan strait is appraised to possess the richest offshore wind resources
   in the world, but also the most severe environment with lots of
   difficulties.
 • Taipower has taken three practices for more green energy and still keep
   the system safe, i.e. produce own green energy in spite of low rate of
   return, strengthen the grid and make the connection more friendly, and
   finally perform a smart dispatch.
 • Working cooperatively with all the developers and stakeholders,
   Taipower is confident to cope with the 10GW more capacity of OWP by
   2035, and we welcome all the partners from all over the world, coming
   to Taiwan to accomplish our common dream of OWP in Asia.
