The Houston area will soon be home to what's being lauded as the first fully sustainable 1-gigawatt data center on a 600-acres site east of Houston.

Data center-as-a-service company ECL, headquartered in Mountain View, California, announced its plans to build the ECL TerraSite-TX1. Hardware and cloud service company Lambda will serve as its first tenant. Lambda and other AI leaders will get access to necessary space and power for the next wave zero emission innovations.

Phase 1 of TerraSite-TX1 will be complete by summer of 2025 with a cost of approximately $450 million. The 50 megawatt of data center capacity will be utilized by data center cloud and AI cloud operators. The 1-gigawatt site will be constructed at a cost of approximately $8 billion. The funding will come from ECL and financial partners.

ECL Terrasite-TX1 comes at a needed time for Texas with The Electric Reliability Council of Texas stating on June 12 that the state’s power grid needs will grow approximately double by 2030. This is due in part to the growth of data centers and AI. The ECL Terrasite-TX1 is built to help eliminate the stress on the state’s power grid and help facilitate “state-level economic development and growth of the AI industry,” according to a news release.

ECL data centers are built to be modular, which allows for expansion in 1-megawatt increments. They are “ built to suit” and delivered in less than 12 months, which is shorter than the industry standard of 36 to 48.

“While others talk about delivering off-grid, hydrogen-powered data centers in five, ten, or 20 years, only ECL is giving the AI industry the space, power, and peace of mind they and their customers need, now,” Yuval Bachar, co-founder and CEO of ECL, says in a news release. “The level of innovation that we have introduced to the market is unprecedented and will serve not only us and our customers but the entire data center industry for decades to come.”

ECL’s ECL-MV1 is the world’s first off-grid, hydrogen-powered modular data center that operates 24/7 with zero emissions, less noise, and a negative water footprint that replenishes water to the community. ECL-MV1 offers a 10x increase in “energy efficiency with a power usage effectiveness of 1.05 and a 7-times improvement in data density per rack, which is ideal for AI high-density demand” according to the release.

“The data center technology committed to by ECL is truly transformative in the industry,” Lambda's Vice President for Data Center Infrastructure Ken Patchett adds. “We believe ECL’s technology could unlock a powerful and eco-conscious foundation for AI advancement. This new infrastructure could give researchers and developers essential computational resources while drastically reducing the environmental impact of AI operations.”

Houston AI energy forecasting company lands investment from Samsung Ventures

funding for forecasts

Amperon, a Houston-based AI-powered forecasting solutions company, has received an investment for an undisclosed amount from Samsung Ventures, the corporate venture arm of Samsung Group.

According to Amperon, the funding will be put toward the company's global growth and next-generation product development. Samsung Ventures invests in emerging businesses developing technologies for the AI, advanced devices and energy-related sectors.

“Samsung Ventures’ investment is a strong validation of our mission to transform the way energy is forecasted and traded,” Sean Kelly, CEO and co-founder of Amperon, said in a news release. “Samsung’s global footprint and leadership in semiconductors, data infrastructure, and AI acceleration make them a natural fit as we expand Amperon’s reach into energy-intensive sectors like data centers. Their track record of scaling next-generation technologies aligns perfectly with our vision to build a more intelligent, resilient, and data-driven energy system.”

Amperon was founded in 2018. Its AI models combine real-time weather, consumption and market data for energy retailers, utilities and independent power producers.

Last year, the company launched its weather-informed grid demand Mid-Term Forecast (MTF), which provides users with data on electricity demand up to seven months in advance. It also secured strategic investments from Acario, the corporate venture capital and innovation division of Tokyo Gas, as well as National Grid Partners, the venture investment and innovation arm of National Grid (NYSE: NGG).

After expanding into Europe in 2024, the company has continued to see international growth, and currently operates in the U.S., Canada, Mexico, Australia, Europe and the Middle East.

“Amperon has demonstrated strong technical capabilities and global traction in a rapidly evolving energy landscape,” a spokesperson for Samsung Ventures added in the release. “Their ability to forecast and model real-time energy data at global scale positions them as a key enabler of smarter energy systems and climate resilience. We are pleased to invest in a company developing technologies that support a more sustainable and digitized world.”

Solar surpasses coal to become ERCOT’s third-largest power source in 2025

by the numbers

Solar barely eclipsed coal to become the third biggest source of energy generated for the Electric Reliability Council of Texas (ERCOT) in 2025, according to new data.

In 2024, solar represented 10 percent of energy supplied to the ERCOT electric grid. Last year, that number climbed to 14 percent. During the same period, coal’s share remained at 13 percent.

From the largest to smallest share, here’s the breakdown of other ERCOT energy sources in 2025 compared with 2024:

  • Combined-cycle gas: 33 percent, down from 35 percent in 2024
  • Wind: 23 percent, down from 24 percent in 2024
  • Natural gas: 8 percent, down from 9 percent in 2024
  • Nuclear: 8 percent, unchanged from 2024
  • Other sources: 1 percent, unchanged from 2024

Combined, solar and wind accounted for 37 percent of ERCOT energy sources.

Looking ahead, solar promises to reign as the star of the ERCOT show:

  • An ERCOT report released in December 2024 said solar is on track to continue outpacing other energy sources in terms of growth of installed generating capacity, followed by battery energy storage.
  • In December, ERCOT reported that more than 11,100 megawatts of new generating capacity had been added to its grid since the previous winter. One megawatt of electricity serves about 250 homes in peak-demand periods. Battery energy storage made up 47 percent of the new capacity, with solar in second place at 40 percent.

The mix of ERCOT’s energy is critical to Texas’ growing need for electricity, as ERCOT manages about 90 percent of the electric load for the state, including the Houston metro area. Data centers, AI and population growth are driving heightened demand for electricity.

In the first nine months of 2025, Texas added a nation-leading 7.4 gigawatts of solar capacity, according to a report from data and analytics firm Wood Mackenzie and the Solar Energy Industries Association.

“Remarkable growth in Texas, Indiana, Utah and other states ... shows just how decisively the market is moving toward solar,” says Abigail Ross Hopper, president and CEO of the solar association.
