Commercial real estate manager Brookfield Properties, a major office landlord in Houston, is plugging into solar energy to power its local portfolio.

The New York City-based company plans to rely on a new-build solar power plant to supply all of the electricity for its 10.3 million-square-foot, 10-building office portfolio in the Houston area. Brookfield’s key properties here include:

  • The 3.1 million-square-foot Allen Center complex
  • The more than 1.1 million-square-foot Heritage Plaza
  • The 1.1 million-square-foot 1600 Smith Street tower
  • The nearly 850,000-square foot TotalEnergies Tower

Laura Montross, vice president of communications for Brookfield Properties, tells Realty News Report that the solar power plant will be operating by 2026.

Each year, the company’s Houston portfolio uses about 90,000 megawatt-hours of electricity, “which is unlikely to take up the total capacity of a new solar power plant,” she says, “so the excess capacity will be available to other buyers or the utility grid operator for purchase.”

Montross says Brookfield is in talks with several developers of solar power plants about the Houston project, but neither a site nor a contractor has been chosen yet.

Brookfield announced June 28 that its entire U.S. office portfolio will run on zero-emissions electricity by 2026. The switch is expected to reduce carbon emissions within the more than 70-million-square-foot portfolio by about 80 percent.

“Instead of taking incremental steps or waiting for others to act, we are completely transforming how we power office buildings throughout the United States,” Ben Brown, managing partner of Brookfield Real Estate, says in a news release.

Brookfield Properties says electricity for the nationwide office portfolio will come from four sources: hydropower (49 percent), solar and wind power (33 percent), and nuclear power (18 percent). Outside Houston, the company maintains a large office presence in the New York City, Los Angeles, Denver, and Washington, D.C. markets.

“Not only will [this strategy] significantly advance our goal of transitioning our entire portfolio to net zero carbon,” Brown says, “but also we are confident that both the increased demand for zero-emissions electricity it will create and the industry precedence it will set will be a game-changer for how state-of-the-art office buildings are powered throughout the country.”

Houston carbon removal company secures $35M in financing

national scale

Houston-based Vaulted Deep, a waste management and carbon removal company, has announced a major $35 million debt facility from Italian investment bank Mediobanca to support its national expansion.

U.K.-based market energy solutions CFP Energy arranged the deal, which is “the largest publicly disclosed U.S. commercial debt deal in durable carbon removal to be secured by long-term purchase contracts,” according to a news release from the companies.

The financing will support new waste disposal sites for Vaulted Deep and advancements of the company’s AI-enabled site development platform. The platform helps identify locations, navigate permitting and optimize injection operations. When candidates are looking for sites, the platform will pull from regulatory, geology and waste-supply data to assist, which Vaulted Deep says will help streamline the permitting process. After the site is operating, the platform helps control algorithms to maximize safe disposal capacity and monitor the process along the way.

"Waste operators across the country need new options as traditional disposal options become limited,” Julia Reichelstein, CEO and co-founder of Vaulted Deep, said in the release. “This financing lets us take on more projects and invest in the tools that help us evaluate and develop new sites faster. This is a meaningful milestone for Vaulted as we move into the next phase of building infrastructure at a much larger scale."

The deal is supported by Vaulted Deep's long-term waste service and carbon removal purchase contracts. The company says it delivered more than 20,000 tons of carbon removal to buyers in the first half of 2026, which is more than it delivered in all of 2025.

"By facilitating these types of transactions, we connect institutional capital with innovative climate technologies, helping accelerate the deployment of high-integrity carbon removal solutions,” Tyler Manchester, head of voluntary carbon for CFP Energy, added in the release. “It reflects growing investor confidence in these solutions, driven by rising demand from corporate buyers seeking permanent pathways to support net-zero commitments and long-term climate strategies."

Beyond the facility, Vaulted Deep has secured $48 million in equity financing in addition to its $8 million from the XPRIZE Carbon Removal competition, backed by Elon Musk’s charitable organization, The Musk Foundation.

The company's well injection technology is used to store organic waste deep underground in stable geologic formations. In 2025, it inked a 12-year deal with Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.
