Adds background and details

July 13 (Reuters) - Meta META.O said on Monday its data center in Richland Parish, Louisiana, will expand to 5 gigawatts of compute capacity, with investment in the project increasing to more than $50 billion.

The planned data center, known as Hyperion, was earlier projected to deliver more than 2 gigawatts of compute capacity to support training of large language models, the technology behind tools such as ChatGPT.

Here are some details:

• The announcement comes as environmental and consumer groups increasingly push back against the energy-intensive buildout.

• U.S. environmental law group Earthjustice's request to investigate the financing of Meta's Louisiana data center project was denied earlier this year.

• Earthjustice had said the financing arrangement could ultimately shift project costs unfairly onto utility customers if Meta walks away from the project before the utility recovers its investment.

• Last year, U.S. President Donald Trump had said the company's data center project would cost $50 billion.

• Since breaking ground in December 2024, local Louisiana businesses have received more than $1.6 billion in contracts from Meta, the company said.

• With this expansion, the company said it plans to invest over $1 billion in local infrastructure improvements, including roads, water and wastewater systems.

• Meta, like its Big Tech peers, has been pouring billions of dollars into AI data centers and computing power, as demand continues to outstrip supply.

• The company has pledged to invest $600 billion in U.S. infrastructure and jobs over the next three years, as it builds out massive data centers to power CEO Mark Zuckerberg's aggressive bets on AI agent technologies.
