Who Is Harald Link?

Harald Link is the third-generation leader of the family behind B.Grimm, one of Thailand’s oldest business groups.

B.Grimm began in Thailand in 1878. The company later came under the stewardship of the Link family, and Harald Link eventually became one of the most important figures in its modern development.

His career is closely connected with Thailand’s industrial and energy sectors.

Although he grew up in Germany and studied in Switzerland, his professional career has been centered primarily in Thailand.

This international background has also contributed to his frequent description as a Thai-German businessman.

Harald Link’s Early Background and Education

Harald Link was born in Switzerland and raised in Germany.

He later studied business administration at the University of St. Gallen in Switzerland, where he earned an MBA.

His education prepared him for a career in business management, but his professional future was strongly connected to his family’s long-established company in Thailand.

In 1978, Link moved to Bangkok and joined B.Grimm.

That year was especially significant because it marked the company’s 100th anniversary.

He initially worked with his uncle Herbert Link while learning the operations and responsibilities of the family enterprise.

The Link Family and B.Grimm Legacy

Harald Link belongs to the third generation of the Link family involved in B.Grimm.

His grandfather, Adolf Link, became connected with the company during the early 20th century and acquired it in 1914.

Harald’s father was Dr. Gerhard Link.

The family continued developing B.Grimm across generations, eventually turning what had started as a pharmacy business into a diversified international group.

Harald Link became Chairman of B.Grimm in 1987.

His leadership marked an important period of expansion.

The business moved beyond its historical activities and developed interests in energy, building systems, healthcare, transportation, lifestyle businesses, real estate, and technology.

This marked the beginning of a business career that would eventually span several decades.

1987: Became Chairman of B.Grimm

Link became Chairman of B.Grimm in 1987.

From this position, he helped guide the group’s diversification and long-term expansion.

1990s: Expansion Into Power Generation

B.Grimm entered an important new phase when it expanded deeper into electricity generation.

The company signed an agreement for its first industrial power plant in 1996.

The plant began commercial operations in 1998.

Energy later became one of B.Grimm’s largest and most visible business activities.

1998–2020: Siam City Cement Board Role

His involvement with another major Thai corporation reflected his broader position in the country’s business community.

2009 Onward: Equestrian Leadership

He has served as President of the Thailand Equestrian Federation since 2009.

He has also held leadership positions in regional equestrian organizations and founded the Thai Polo & Equestrian Club.

2010–2023: True Corporation

Link served as an independent director of True Corporation from 2010 until 2023.

He also chaired its Compensation and Nominating Committee.

This position extended his board-level experience beyond B.Grimm.

2016–2022: B.Grimm Power Chairman

Harald Link served as Chairman of B.Grimm Power during an important period in the company’s development.

The company was preparing for a major transition from privately controlled operations toward the public capital markets.

2017: B.Grimm Power Stock Market Listing

B.Grimm Power was listed on the Stock Exchange of Thailand in 2017.

The listing was historically important because it represented the first initial public offering from the B.Grimm group.

The public listing provided a larger platform for future investment and international expansion.

2020–2025: Executive Leadership at B.Grimm Power

Link held senior executive responsibility at B.Grimm Power during the first half of the 2020s.

His period as Group President ended on September 16, 2025.

September 2025: Returned to Chairman Role

On September 17, 2025, Harald Link became Chairman of the Board of B.Grimm Power again.

At the same time, the company introduced a structure involving three presidents responsible for different areas of the business.

This means articles that still call Harald Link the CEO of B.Grimm Power or current Group President can be misleading.

His verified position in 2026 is Chairman of the Board.

Harald Link and B.Grimm Power

B.Grimm Power is the most publicly visible part of the wider B.Grimm business network.

The company operates power projects in Thailand and internationally.

Its activities include conventional generation, solar energy, wind power, hydropower, and other forms of renewable energy.

As of 2026, the company’s published figures showed total generating capacity of approximately 4,764 megawatts across 15 countries.

Its long-term target is to reach 10,000 megawatts of capacity by 2030.

Renewable energy is becoming increasingly important to its strategy.

The company aims for renewable energy to account for more than half of its generating capacity by 2030.

Is Harald Link the CEO of B.Grimm Power?

The phrase CEO of B.Grimm Power frequently appears in searches related to Harald Link, but it does not accurately describe his current role.

Harald Link previously held top executive responsibilities at B.Grimm Power.

He served as Group President until September 16, 2025.

Since September 17, 2025, his verified role has been Chairman of the Board of B.Grimm Power.

The distinction is important because the chairman oversees board-level governance, while day-to-day executive responsibilities are now divided among the company’s senior presidents and management team.

Harald Link’s Current Business Strategy

Renewable Energy Expansion

B.Grimm Power has made renewable energy a major part of its long-term growth strategy.

The company has expanded into solar, wind, and hydropower projects in multiple countries.

Its international operations are designed to reduce dependence on a single market.

United States Hydropower Investment

In January 2026, a B.Grimm Power subsidiary completed a US$230 million investment for a 25% interest in New England Reliable Hydropower Holdings.

The business controls a portfolio of hydropower facilities in the United States.

The transaction strengthened B.Grimm Power’s international renewable-energy presence.

Digital Infrastructure

B.Grimm is also entering areas connected to artificial intelligence, cloud computing, and data infrastructure.

A partnership involving Digital Edge is developing a hyperscale data center campus in Thailand’s Eastern Economic Corridor.

The planned facility has a capacity of 96 megawatts and is expected to begin operations in 2027.

This strategy connects B.Grimm’s energy capabilities with the growing electricity demands of modern digital infrastructure.

Harald Link Family

Harald Link is married and has two children.

His wife has been publicly identified as Princess Assunta of Liechtenstein.

The couple married in 1981.

Their children are Caroline Link and Felix Danai Link.

Both children are involved in B.Grimm Power as board directors.

This involvement is significant because it represents another generation of the family entering the group’s leadership structure.

Caroline Link has particularly attracted attention as a possible future leader within the wider B.Grimm organisation.

Her board responsibilities include participation in committees connected with nomination, compensation, corporate governance, and sustainability.

Harald Link Net Worth and 1.7 Billion USD Estimate

Harald Link is widely recognized as one of Thailand’s wealthy business figures.

Forbes estimated his fortune at approximately 1.7 billion USD in 2026.

This number should be understood correctly.

It is an estimated net worth based on business interests and available financial information, not an amount publicly declared by Harald Link himself.

His largest transparent listed investment is his stake in B.Grimm Power.

As of March 11, 2026, he directly owned 621,399,700 shares, representing approximately 23.84% of the company.

He was the second-largest named shareholder at that time.

His wealth can rise or fall as stock prices, investments, company values, and other assets change.

For that reason, the 1.7 billion USD figure should always be connected with the year 2026 rather than treated as a permanent number.

Other Corporate Positions

Harald Link is also an independent director of Indorama Ventures Public Company Limited.

He joined its board in November 2021.

Indorama Ventures is a major global chemical company based in Thailand.

His involvement demonstrates that his board experience extends beyond businesses controlled by his own family group.

Link has previously served on the boards of companies including True Corporation and Siam City Cement.

Equestrian Sports and Polo

Harald Link has a longstanding interest in horses and equestrian sports.

He has served as President of the Thailand Equestrian Federation since 2009.

He has also held regional leadership positions within Southeast Asian equestrian organizations.

Link founded the Thai Polo & Equestrian Club.

His involvement combines personal interest with administrative work intended to develop equestrian sport in Thailand.

He has also received recognition for his contribution to the sport.

Charity, Culture, and Public Service

Harald Link is involved with several charitable and cultural organisations.

He serves as Chairman of the Royal Bangkok Symphony Orchestra Foundation.

His involvement supports classical music and the development of orchestral performance in Thailand.

He has also held positions connected with the Thai Red Cross Society, the Princess Mother’s Charities Fund of Thailand, the Siri Watana Cheshire Foundation, and the Chaipattana Foundation.

These activities form an important part of his public work beyond business.

Awards and International Recognition

Harald Link has received several official honours during his career.

They include the Order of Merit of the Federal Republic of Germany, First Class.

He has also received Thai royal decorations, including honours within the Order of the Crown of Thailand and the Order of the White Elephant.

His business leadership has additionally received recognition from regional financial and corporate-governance publications.

Such awards reflect his long-standing visibility within both Thai and international business circles.

Why Harald Link Is Important in Thailand’s Business World

Harald Link’s importance comes from the length and scale of his involvement in B.Grimm.

He did not create B.Grimm from the beginning.

Instead, he inherited responsibility for a historic family enterprise and helped move it into new industries and countries.

His strongest impact has been in energy.

B.Grimm Power developed into a publicly traded company with operations extending far beyond Thailand.

His career also illustrates how an old family company can transition toward renewable energy, professional management, public ownership, and next-generation leadership.

Conclusion

Harald Link is a Thai-German businessman whose career is closely tied to the growth of B.Grimm from a historic family company into an international energy and industrial group.

He joined B.Grimm in 1978, became chairman in 1987, and spent decades expanding its operations.

As of August 2026, he is Chairman of B.Grimm Group and Chairman of the Board of B.Grimm Power.

His estimated 1.7 billion USD fortune in 2026 reflects the substantial value connected with his business interests, although the amount remains an external estimate.

From renewable power and international investment to equestrian sport and cultural organisations, Harald Link remains an influential figure in Thailand’s corporate landscape.
