Nowadays, eco-friendly energy related businesses such as wind power generation, electric vehicles and hydrogen vehicles are receiving a lot of attention.

It is regarded as the core of the 4th industrial revolution and a future growth engine. Today (6th), we will present some problems that need to be addressed by field.

First, offshore wind power generation.

There is a large-scale wind farm on the west coast, and several defects have been confirmed, including a broken blade of the generator.



First, reporter No.



<Reporter> This



is a demonstration complex for offshore wind power generation in the southwest sea, located 9km off the coast of Buan-gun, Jeollabuk-do.



It was created by investment by KEPCO and six power generation companies. The wings of 20 generators with a height of 90m are turned into sea wind to generate electricity.



The plan is to increase power generation to 2.46GW, which can power 2.24 million households by 2028.

In July, the'Green New Deal Vision Declaration Ceremony' was held here. Offshore wind power is selected as a business.



However, since September of last year, the blades of the generator have been broken.



These defects were identified in 17 out of 20 generators, all of which had a carbon fiber blade.



It was caused by defects in parts and poor contact with the blade load of 300 million won each.



The carbon fiber technology applied to the blade is a national R&D project with KRW 8.4 billion in government contributions.



The demonstration complex is undergoing limited power generation by reducing the amount of power generation by a third due to defective parts.

It is important to ensure blade stability.] The



operator of Korea Offshore Wind Power has announced that it will replace defective parts by next June, but the offshore wind power business has been disrupting from the start.
