Meta (NASDAQ: FB) has unveiled plans to invest a further US$800 million into Facebook’s Los Lunas data centre in New Mexico.

The capital expenditure will bring the overall investment into the campus to $2.2 billion deployed to build nearly 3.8 million-square-foot of data centre space.

The new financing will add two buildings to the site’s current six planned facilities, each with around 30 data halls. Building number six is forecasted to be brought online this November.

A further 200 operational jobs are expected to be added at the site with new buildings seven and eight, doubling the current workforce.

Meta said the project will take three to four years to complete and employ 1,000 construction workers.

The company said: “From the beginning, we have been committed to supporting this community, and we know water is an important issue in New Mexico. Today, we are also announcing a new goal to restore 200% of the water our data centre consumes into the New Mexico watersheds.

“To date, we have invested in a total of five local water restoration projects, and in 2020, these projects restored approximately 64 million gallons of water right here in New Mexico. Through these projects, our Los Lunas Data Center already restores more water than it consumes, and as we continue to grow, we want to make sure we are doing our part to replenish New Mexico’s water resources through additional partnerships with local environmental organisations.”

In addition to the data centre expansion, Facebook has also announced that we are partnering with Lokket and Valencia County to bring free WiFi to up to 900 homes in the Los Lunas area.

The $225,000 grant will be used to deploy and install hardware in homes throughout eastern Valencia County and place distribution points on fire stations, schools and other buildings in the area. Since 2017, Facebook has provided over $2.3 million in grants and donations to local organisations.

“We continue to invest in new wind and solar resources in the state,” Facebook said. “We are adding two new solar projects to our portfolio—a 190MW project in Valencia County and a 50MW project in Sandoval County. That brings our investment to 10 new renewable energy projects across six counties in New Mexico. During their construction, these projects are supporting 1,400 construction jobs and providing $120 million in construction labour income.

“Los Lunas has been a terrific location for our data centre since we broke ground five years ago this month. During that time, we have erected nearly 20,000 tons of steel, poured 126,792 cubic yards of concrete, recycled 88% of construction waste and had 1,100 construction workers on site at peak.”

Facebook rebranded as Meta on October 28 in a move CEO Mark Zuckerberg said it will align the business with his vision of the metaverse.

The name change will see Facebook, Instagram, WhatsApp and other brands become subsidiaries of Meta, which replaced Facebook as the parent company.

From December 1, 2021, the company will also change its stock market ticker from FB to MVRS.
