$360M DOE grant to fund project that will connect ERCOT to US power grid

powering on

Thanks to recently announced funding, the power grid for the territory served by the Electric Reliability Council of Texas (ERCOT) will be connected to grids in other states.

Officials hope building a 320-mile transmission line that connects the ERCOT electric grid to electric grids in the Southeast will prevent power outages like the massive blackout that occurred in 2022 when a winter storm blasted Texas.

San Francisco-based Pattern Energy says its Southern Spirit project will cost more than $2.6 billion. Full-scale construction is supposed to get underway in 2028, and the project is set to go online in 2031.

The U.S. Department of Energy recently approved up to $360 million for the transmission project. The transmission line will stretch from Texas’ border with Louisiana to Mississippi. It’ll supply about 3,000 megawatts of electricity in either direction. That’s enough power for about 750,000 residential customers during ERCOT’s peak hours.

ERCOT’s more than 54,100 miles of transmission lines supply power to about 90 percent of Texans.

“The U.S. transmission network is the backbone of our nation’s electricity system. Though our grid has served U.S. energy needs for more than a century, our country’s needs are changing,” David Turk, under secretary at the Department of Energy, says in a news release.

“DOE’s approach to deploying near-term solutions and developing long-term planning tools will ensure our electric grid is more interconnected and resilient than ever before,” Turk adds, “while also supporting greater electricity demand.”

The other three projects that recently received funding from the DOE include:

  • Aroostook Renewable Project, which will construct a new substation in Haynesville, Maine, and a 111-mile transmission line connecting to a substation in Pittsfield, Maine.
  • Cimarron Link, a 400-mile HVDC transmission line from Texas County, Oklahoma to Tulsa, Oklahoma
  • Southline, which will construct a 108-mile transmission line between Hidalgo County, New Mexico, and Las Cruces, New Mexico. The DOE previously supported a 175-mile line from Hidalgo County, New Mexico, to Pima County, Arizona, in Southline Phase 1 on the first round of the Transmission Facilitation Program.

This month's funding completes the $2.5 billion in awards from the Transmission Facilitation Program which is administered through the Building a Better Grid Initiative that launched in January 2022. Its mission has been to develop nationally significant transmission lines, increase resilience by connecting regions of the country and improve access to clean energy sources, according to the DOE.

Earlier this year, ERCOT, which manages 90 percent of Texas’ power supply, forecasted a major spike in demand for electricity over the next five to seven years

California co. announces fully sustainable, hydrogen-powered data center in Houston

moving in

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 energy storage company forms $10M partnership to enhance storage in ERCOT region

teaming up

A Houston-based company that's developing long-duration energy storage solutions announced a $10 million investment and partnership with a Texas corporation.

Quidnet Energy has entered into a strategic partnership with Hunt Energy Network, an affiliate of Dallas-based Hunt Energy that develops and operates distributed energy resources. The two Texas companies will work on a build-transfer program for 300 MW of storage projects that uses Quidnet's Geomechanical Energy Storage technology in the Electric Reliability Council of Texas (ERCOT) grid operating region.

“Hunt Energy Network brings an extensive and proven track record across diverse energy businesses, making them an ideal partner to address the need for large-scale, long-duration energy storage in Texas,” Joe Zhou, CEO of Quidnet Energy, says in a news release. “We’re thrilled to have them as an investor, partner, and board member, and we look forward to jointly advancing the deployment of energy storage solutions, particularly in regions like ERCOT where the need is most pressing.”

Todd Benson, the chief innovation officer of Hunt Energy, will join Quidnet's board of directors as a part of the partnership.

“Quidnet Energy's GES technology presents a unique opportunity to revolutionize energy storage, and we’re excited to invest in a solution that purposefully transforms existing resources to expand access to long-duration storage,” adds Pat Wood, III, CEO of HEN. “ERCOT's growing supply of renewable energy makes this region ideal for the deployment of our technology, and we’re pleased to work with another Texas innovator to build a more resilient grid for all ERCOT customers.”

Quidnet’s technology, which can provide over 10 hours of storage, uses drilling and hydropower machinery to store renewable energy. Essentially, the company, founded in 2013, is using water storage to power carbon-free electric grid approach to energy.

One year ago, Quidnet secured $10 million from the U.S. Department of Energy Advanced Research Projects Agency-Energy, or ARPA-E. Just a few months after that, the company received an additional $2 million from the DOE for its project, entitled "Energy Storage Systems for Overpressure Environments," which is taking place in East Texas.

Report: Solar tops coal in Texas for energy generation for the first time

by the numbers

For the first time in Texas, according to a recent report, solar energy generation surpassed the output by coal.

The report — from the Institute For Energy Economics and Financial Analysis — sourced the Energy Information Administration’s hourly grid monitor for March 2024. This shift in a predominantly oil and gas dominated history of Texas energy output, was due to solar power’s 3.26 million megawatt-hours to Electric Reliability Council of Texas (ERCOT) grid, compared to coal’s 2.96 million MWh.

In addition, coal’s market share fell below 10 percent to 9 percent for the first time ever, to just over 9 percent. The increase in solar energy pushed solar’s share of ERCOT generation to more than 10 percent for the month, which was also a first.

Due to its sheer size, Texas is the No.1 state for solar capacity. According to the report from SmartAsset, the Lone Star State has the most clean energy capacity at 56,405 megawatts, but continues to trail states with similar geographic characteristics in overall clean energy prevalence.

Texas only 38 percent of the state’s electricity capacity comes from clean electricity, and it has the second-largest solar capacity, which means Texas has the most means, space, and potential to accommodate cleaner electricity. Texas as a whole, ranked No. 22 on the list for states with the most clean energy in the SmartAsset report.

In Texas, generation in March 2024 was 1.17 million MWh more year-over-year, which is a 56 percent increase. ERCOT data shows that the system currently has 22,710 megawatts (MW) of operational solar capacity according to IEEFA, and is expected to expand by almost one-third by the end of 2024 with an additional 7,168 MW of capacity added. The number just considers Texas solar projects that have set aside the financing required to get onto the ERCOT grid and that have a signed interconnection agreement.

Texas burned 50.7 million tons of coal for electricity, which was 13 percent of the U.S. total in 2023 according to the EIA grid monitor. Coal's annual share of ERCOT demand ranged from 36 percent to 40 percent from 2003 through 2014. The last year percent. In 2020, coal was under 20 percent in 2020; and was less than 15 percent in 2023 supplying just 13.9 percent of the system’s total demand.

The IEEFA notes coal’s low March production is important because in recent years it has been the moderate temperatures of April and May and steady winds that have affected the usage and the market share.

Oregon energy storage company plans 450-megawatt facility in Galveston County

coming soon

An Oregon startup has purchased a 450-megawatt battery energy storage project in Galveston County.

GridStor, a Portland, Oregon-based developer and operator of battery energy storage systems, bought the project from Moab, Utah-based Balanced Rock Power. The Utah company develops utility-scale solar and energy storage projects.

Financial terms of the deal weren’t disclosed.

GridStor, founded in 2022, is backed by Goldman Sachs Asset Management. The Portland Business Journal reported last November that Goldman Sachs had raised a $410 million fund to fuel its energy storage strategy.

Construction on the Evelyn Battery Energy Storage project is scheduled to get underway this summer, with the system projected to go online in the spring of 2025.

“Battery storage is a scalable and near-term solution to powering historic load growth in Texas,” Chris Taylor, CEO of GridStor, says in a news release. “Every day, batteries are consistently providing energy to stabilize the power system and meet hours of greatest demand in the state.”

The GridStor project will boost the Electric Reliability Council of Texas (ERCOT) grid. It’s GridStor’s first acquisition in ERCOT territory.

The project will be built near the Hidden Lakes substation, which is owned by Texas-New Mexico Power, which now just serves Texas. This proximity will enable batteries to quickly begin grid-connected operations.
