➢ 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.

⚫ The 10-minute average wind speed of 50year return
periods estimated as 57m/s, and 3-sec gust as 77m/s.
⚫ Weak bearing capacity of soil seabed without rock.
⚫ Local installation vessels are lack.
⚫ Steel is tent to rust due to high temp. & humidity.
⚫ Local supply chain capability isn’t enough.
⚫ There is no certificated port or wharf for offshore
wind farm construction.
⚫ Local marine technicians are lack.
⚫ Migrating birds & ocean mammals guarded by NGO.
⚫ The negotiation between developer and fishermen
group is not proceeding smoothly.

Challenge 1: ET-proof wind turbine to be manufactured
⚫ Considering the severe environment with typhoons and
earthquakes in Taiwan strait, design level in compliance with
IEC Class I at least and Class T recommended.
⚫ Although several models of offshore wind turbines available,
but ET-proof wind turbine can be manufactured locally
in time?

⚫ Wind turbine wharf： Taichung harbor #5A and #5B wharfs
will be ready by 2020. And will be more available if needed.
⚫ Substructure wharf ： Hsinta harbor far-ocean
wharf will be ready by the end of 2019.

• 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.

18➢ 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.

21Seek 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.
23➢ 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.
