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

CenterPoint Energy announces $5B expanded resiliency plan

doubling down

CenterPoint Energy disclosed that it's completed its core resiliency actions first phase of its Greater Houston Resiliency Initiative. The company also reports that it's outlined extra upcoming efforts.

Following the unprecedented outages of Hurricane Beryl, CenterPoint outlined its GHRI in August. As of last week, the first phase, which included more than 40 critical actions in total to strengthen the electric grid, has been completed ahead of schedule.

The company also announced a second phase of GHRI and approximately $5 billion in resiliency investment from 2026 to 2028, a figure that's around twice as much as initially promised.

"We have heard the call to action from our customers and elected officials, and we are responding with bold actions," says Jason Wells, CenterPoint president and CEO, in a statement. "Our defining goal, going forward, is this: to build the most resilient coastal grid in the country that can better withstand the extreme weather of the future. To achieve this ambition, we will undertake a historic level of resiliency actions and investment, because this is what the people of the Greater Houston area expect and deserve."

According to CenterPoint, the second phase will include system hardening, strategic undergrounding, self-healing grid technology, and further enhancements to the company's outage tracker.

CenterPoint outlined its recently completed efforts, including installing over 300 automation devices and more than 1,000 stronger poles, as well as removing hazardous vegetation from more than 2,000 miles of power lines. Next up, CenterPoint says it's near-term actions will include further grid strengthening, public communication improvements, and enhancements to local, community, and emergency partnerships. The details of this phase, which will take place between September 1 to June 1, will be released by September 30.

In the company's longer-term action plan, CenterPoint commits to $5 billion in upgrades from 2026 to 2028 — "the largest investment in Greater Houston infrastructure in the company's nearly 160-year history."

"The mission of this longer-term plan of action is to build the most resilient coastal grid in the country by investing in a smarter grid of the future that can better withstand a broad spectrum of risks," reads the statement. "The proposal, and the entire scope of these actions will be outlined in a new system resiliency plan that is expected to be filed with the Public Utility Commission of Texas on or before January 31, 2025."

CenterPoint reports that lawmakers have received this information directly, and that the plan will be shaped by feedback from its customers, experts, and stakeholders, including elected officials and local agencies.

Houston renewables developer powers up projects in southern region of the US

shine bright

Houston-based renewable energy developer EDP Renewables is making big moves in the Southern United States with its latest solar park projects.

EDPR celebrated the inauguration of Pearl River Solar Park in Scott County, Mississippi, that has an installed capacity of 210 megawatt peak, which produces enough power to meet the energy needs of more than 27,000 average Mississippi homes.

The project consists of 400,000 monofacial and bifacial tracking photovoltaic panels that will contribute clean, cost-competitive power to the state’s electric grid. Pearl River will provide more than $50 million in payments to local governments throughout its operating life, benefiting schools, health care facilities, fire departments, and other county services, as well as create hundreds of jobs, according to EDPR.

"We are thrilled to finally see Pearl River begin operations,” Sandhya Ganapathy, CEO of EDPR North America, says in a news release. “Solar power is a win-win in Mississippi, as it accelerates the deployment of clean energy to the grid and contributes to the state’s decarbonization objectives. The project will immediately go to work to provide Mississippi with a readily available clean energy resource.”

A second project is currently under development for Ragsdale Solar Park in Canton, Mississippi. The project is expected to provide over $36 million to local governments and $15 million to landowners over the course of its lifespan once it becomes operational.

Ragsdale is expected to generate 100 MW of energy, which is equivalent to the consumption of 15,000 average Mississippi homes. According to the company, once operational, it will create over 100 construction jobs and will create three permanent jobs.

In May, EDPR opened its Crooked Lake Solar Park near Blytheville in Mississippi County, Arkansas, which is a 175-megawatt project. The company says it will generate enough energy to power the equivalent of 30,000 Arkansas homes each year.

In April, EDPR completed Misenheimer Solar Park in Stanly County, North Carolina. The solar project has an installed capacity of 74 megawatts, which is one of the largest in the state. Misenheimer Solar Park will generate enough energy annually to power the equivalent of more than 12,000 North Carolina homes while providing economic and environmental benefits, according to EDPR.

Combining batteries with green energy is a fast-growing climate solution. Photo via Getty Images

Batteries and green energies like wind and solar combine for major climate solution across Texas, U.S.

team work

In the Arizona desert, a Danish company is building a massive solar farm that includes batteries that charge when the sun is shining and supply energy back to the electric grid when it's not.

Combining batteries with green energy is a fast-growing climate solution.

“Solar farms only produce when the sun shines, and the turbines only produce when the wind blows,” said Ørsted CEO Mads Nipper. “For us to maximize the availability of the green power, 24-7, we have to store some of it too.”

The United States is rapidly adding batteries, mostly lithium-ion type, to store energy at large scale. Increasingly, these are getting paired with solar and wind projects, like in Arizona. The agencies that run electric grids, utility companies and developers of renewable energies say combining technologies is essential for a green energy future.

Batteries allow renewables to replace fossil fuels like oil, gas and coal, while keeping a steady flow of power when sources like wind and solar are not producing. For example, when people are sleeping and thus using less electricity, the energy produced from wind blowing through the night can be stored in batteries — and used when demand is high during the day.

Juan Mendez, a resident of Tempe, Arizona, gets power from local utility Salt River Project, which is collaborating with Ørsted on the Eleven Mile Solar Center. As a state senator, Mendez pushed SRP to move to renewable energies.

He thinks the power company is still investing too much in gas and coal plants, including a major expansion planned for a natural gas plant in Coolidge, Arizona, near the solar center.

“This solar-plus-storage is a good step, but SRP needs to do more to provide clean energy and clean up our air and help address climate change," Mendez said.

The utility said it’s adding more renewables to its energy mix and recently pledged to zero out its emissions by 2050.

The U.S. has the second most electrical storage in the world, after China. In 2023, the U.S. added an estimated 7.5 gigawatts — 62% more than in 2022, according to the BloombergNEF and the Business Council for Sustainable Energy factbook. That amount can power 750,000 homes for a day and brings the total amount of installed capacity nationwide to nearly enough for 2 million homes for one day, according to BloombergNEF.

In the U.S., California leads in energy storage as it aggressively cuts greenhouse gas emissions. It has twice as much as any other state. Residential, commercial and utility-scale battery installations increased by 757% there over just four years, meaning there's now enough to power 6.6 million homes for up to four hours, according to the California Energy Commission.

That's partly because in 2013, the California Public Utilities Commission told utilities to buy energy storage with a target to be met by 2020. Since then, power companies have continued to add more batteries to help the state meet clean electricity requirements.

Southern California Edison is one utility adding thousands of hours of energy storage. It is putting in solar-plus-batteries to replace some power plants that burn natural gas and would typically supply electricity in the evening.

“If it’s just clean and not reliable, you really don’t have anything,” said William Walsh, vice president for energy procurement and management. “We need both.”

In California, batteries proved their value in September 2022, as the West was experiencing a long heat wave that sent temperatures into the triple digits. Electricity demand reached the highest the state had ever seen on Sept. 6, 2022, as people cranked up air conditioners.

Walsh credits the batteries added to the grid between 2020 and 2022 with helping to avoid blackouts. Two years earlier, there were rolling electricity outages in California during a similar extreme heat wave.

Texas has the second-most battery storage after California. Last month, Schneider Electric announced it's teaming up with energy company ENGIE North America on solar and battery systems in Texas to get closer to the French multinational’s 100% renewable energy goal in the U.S. and Canada. Before the Inflation Reduction Act, a major climate law passed in 2022, the deal and the necessary $80 million investment would not have been possible, said Hans Royal, Schneider Electric's senior director for renewable energy and carbon advisory.

Royal is advising other global Fortune 500 companies it works with to get into the market.

“The industry needs that, the grid needs it," said Royal.

Back in Arizona, Ørsted’s Eleven Mile Solar Center covers 2,000 acres in rural Pinal County. It has 857,000 solar panels and more than 2,000 cubes that look like large shipping containers but contain battery modules. Ørsted also has large solar and storage projects in Texas and Alabama, and in Europe.

When the Arizona facility opens this summer, most power from the solar farm will go to Facebook owner Meta's data center in Mesa. The solar power not needed by Meta, in addition to the power stored in the batteries, will go to the local utility's customers. The new batteries can ensure power to roughly 65,000 homes during peak hours of demand.

“What I think is exciting is just how rapidly this market is moving," said Yayoi Sekine, head of energy storage at BloombergNEF. “There's so much pressure for the U.S. and different regions to decarbonize, and storage is one of the major technologies to enable that. There's a lot of momentum."

NERC warns of summer energy shortfalls–what you can do now

THINGS ARE HEATING UP

The North American Electric Reliability Council (NERC) issued a warning with the 2023 Summer Reliability Assessment yesterday – energy shortages could be coming this summer for two-thirds of North America if temperatures spike higher than normal.

“Increased, rapid deployment of wind, solar and batteries have made a positive impact,” Mark Olson, NERC’s manager of reliability assessments says in the release. “However, generator retirements continue to increase the risks associated with extreme summer temperatures, which factors into potential supply shortages in the western two-thirds of North America if summer temperatures spike.”

For Texans, the combined risk of drought and higher-than-normal temperatures could stress ERCOT system resources, especially in the case of reduced wind. But before there’s a mad rush on generators, keep in mind, electricity consumers can take simple actions to minimize the possibility of widespread shortfalls.

Electricity demand begins rising daily around 2 P.M. in the summer and peaks in the final hours of daylight. These hours are generally not only the warmest hours of the day but also the busiest. People return from work to their homes, crank down the air conditioner, turn on TVs, run a load of wash, and prepare meals using multiple electric-powered appliances.

If everyone takes one or two small steps to avoid unnecessary stress on the grid in the hours after coming home from work, we can prevent energy shortfalls. Modify routines now to get into the habit of running the dishwasher overnight, using the washer and dryer before noon or after 8 pm and pulling the shades down in the bright afternoon hours of the day.

Try to delay powering up devices – including EVs – until after dark. Turn off and unplug items to avoid sapping electricity when items are not in use. And if you can bear it, nudge that thermostat up a couple of degrees.

Energy sustainability demands consistent collaboration and coordination from every consumer of energy. Let’s get in the habit of acting neighborly now with conservative electricity practices before we start seeing temperatures–of both the literal and figurative kind–flare.

Houston researchers make headway on developing low-cost sodium-ion batteries

energy storage

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

ExxonMobil lands major partnership for clean hydrogen facility in Baytown

power deal

Exxon Mobil and Japanese import/export company Marubeni Corp. have signed a long-term offtake agreement for 250,000 tonnes of low-carbon ammonia per year from ExxonMobil’s forthcoming facility in Baytown, Texas.

“This is another positive step forward for our landmark project,” Barry Engle, president of ExxonMobil Low Carbon Solutions, said in a news release. “By using American-produced natural gas we can boost global energy supply, support Japan’s decarbonization goals and create jobs at home. Our strong relationship with Marubeni sets the stage for delivering low-carbon ammonia from the U.S. to Japan for years to come."

The companies plan to produce low-carbon hydrogen with approximately 98% of CO2 removed and low-carbon ammonia. Marubeni will supply the ammonia mainly to Kobe Power Plant, a subsidiary of Kobe Steel, and has also agreed to acquire an equity stake in ExxonMobil’s low-carbon hydrogen and ammonia facility, which is expected to be one of the largest of its kind.

The Baytown facility aims to produce up to 1 billion cubic feet daily of “virtually carbon-free” hydrogen. It can also produce more than 1 million tons of low-carbon ammonia per year. A final investment decision is expected in 2025 that will be contingent on government policy and necessary regulatory permits, according to the release.

The Kobe Power Plant aims to co-fire low-carbon ammonia with existing fuel, and reduce CO2 emissions by Japan’s fiscal year of 2030. Marubeni also aims to assist the decarbonization of Japan’s power sector and steel manufacturing industry, chemical industry, transportation industry and various others sectors.

“Marubeni will take this first step together with ExxonMobil in the aim of establishing a global low-carbon ammonia supply chain for Japan through the supply of low-carbon ammonia to the Kobe Power Plant,” Yoshiaki Yokota, senior managing executive officer at Marubeni Corp., added in the news release. “Additionally, we aim to collaborate beyond this supply chain and strive towards the launch of a global market for low-carbon ammonia. We hope to continue to actively cooperate with ExxonMobil, with a view of utilizing this experience and relationship we have built to strategically decarbonize our power projects in Japan and Southeast Asia in the near future.”

Houston expert: The role of U.S. LNG in global energy markets

guest column

The debate over U.S. Liquefied Natural Gas (LNG) exports is too often framed in misleading, oversimplified terms. The reality is clear: LNG is not just a temporary fix or a bridge fuel, it is a fundamental pillar of global energy security and economic stability. U.S. LNG is already reducing coal use in Asia, strengthening Europe’s energy balance, and driving economic growth at home. Turning away from LNG exports now would be a shortsighted mistake, undermining both U.S. economic interests and global energy security.

Ken Medlock, Senior Director of the Baker Institute’s Center for Energy Studies, provides a fact-based assessment of the U.S. LNG exports that cuts through the noise. His analysis, consistent with McKinsey work, confirms that U.S. LNG is essential to balancing global energy markets for the decades ahead. While infrastructure challenges and environmental concerns exist, the benefits far outweigh the drawbacks. If the U.S. fails to embrace its leadership in LNG, we risk giving up our position to competitors, weakening our energy resilience, and damaging national security.

LNG Export Licenses: Options, Not Guarantees

A common but deeply flawed argument against expanding LNG exports is the assumption that granting licenses guarantees unlimited exports. This is simply incorrect. As Medlock puts it, “Licenses are options, not guarantees. Projects do not move forward if they are unable to find commercial footing.”

This is critical: government approvals do not dictate market outcomes. LNG projects must navigate economic viability, infrastructure feasibility, and global demand before becoming operational. This reality should dispel fears that expanded licensing will automatically lead to an uncontrolled surge in exports or domestic price spikes. The market, not government restrictions, should determine which projects succeed.

Canada’s Role in U.S. Gas Markets

The U.S. LNG debate often overlooks an important factor: pipeline imports from Canada. The U.S. and Canadian markets are deeply intertwined, yet critics often ignore this reality. Medlock highlights that “the importance to domestic supply-demand balance of our neighbors to the north and south cannot be overstated.”

Infrastructure Constraints and Price Volatility

One of the most counterproductive policies the U.S. could adopt is restricting LNG infrastructure development. Ironically, such restrictions would not only hinder exports but also drive up domestic energy prices. Medlock’s report explains this paradox: “Constraints that either raise development costs or limit the ability to develop infrastructure tend to make domestic supply less elastic. Ironically, this has the impact of limiting exports and raising domestic prices.”

The takeaway is straightforward: blocking infrastructure development is a self-inflicted wound. It stifles market efficiency, raises costs for American consumers, and weakens U.S. competitiveness in global energy markets. McKinsey research confirms that well-planned infrastructure investments lead to greater price stability and a more resilient energy sector. The U.S. should be accelerating, not hindering, these investments.

Short-Run vs. Long-Run Impacts on Domestic Prices

Critics of LNG exports often confuse short-term price fluctuations with long-term market trends. This is a mistake. Medlock underscores that “analysis that claims overly negative domestic price impacts due to exports tend to miss the distinction between short-run and long-run elasticity.”

Short-term price shifts are inevitable, driven by seasonal demand and supply disruptions. But long-term trends tell a different story: as infrastructure improves and production expands, markets adjust, and price impacts moderate. McKinsey analysis suggests supply elasticity increases as producers respond to price signals. Policy decisions should be grounded in this broader economic reality, not reactionary fears about temporary price movements.

Assessing the Emissions Debate

The argument that restricting U.S. LNG exports will lower global emissions is fundamentally flawed. In fact, the opposite is true. Medlock warns against “engineering scenarios that violate basic economic principles to induce particular impacts.” He emphasizes that evaluating emissions must be done holistically. “Constraining U.S. LNG exports will likely mean Asian countries will continue to turn to coal for power system balance,” a move that would significantly increase global emissions.

McKinsey’s research reinforces that, on a lifecycle basis, U.S. LNG produces fewer emissions than coal. That said, there is room for improvement, and efforts should focus on minimizing methane leakage and optimizing gas production efficiency.

However, the broader point remains: restricting LNG on environmental grounds ignores the global energy trade-offs at play. A rational approach would address emissions concerns while still recognizing the role of LNG in the global energy system.

The DOE’s Commonwealth LNG Authorization

The Department of Energy’s recent conditional approval of the Commonwealth LNG project is a step in the right direction. It signals that economic growth, energy security, and market demand remain key considerations in regulatory decisions. Medlock’s analysis makes it clear that LNG exports will be driven by market forces, and McKinsey’s projections show that global demand for flexible, reliable LNG is only increasing.

The U.S. should not limit itself with restrictive policies when the rest of the world is demanding more LNG. This is an opportunity to strengthen our position as a global energy leader, create jobs, and ensure long-term energy security.

Conclusion

The U.S. LNG debate must move beyond fear-driven narratives and focus on reality. The facts are clear: LNG exports strengthen energy security, drive economic growth, and reduce global emissions by displacing coal.

Instead of restrictive policies that limit LNG’s potential, the U.S. should focus on expanding infrastructure, maintaining market flexibility, and supporting innovation to further reduce emissions. The energy transition will be shaped by market realities, not unrealistic expectations.

The U.S. has an opportunity to lead. But leadership requires embracing economic logic, investing in infrastructure, and ensuring our policies are guided by facts, not political expediency. LNG is a critical part of the global energy landscape, and it’s time to recognize its long-term strategic value.
