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.

ExxonMobil names new partner to bolster US lithium supply chain with offtake agreement

ev supplies en route

Spring-headquartered ExxonMobil Corp. has announced a new MOU for an offtake agreement for up to 100,000 metric tons of lithium carbonate.

The agreement is with LG Chem, which is building its cathode plant in Tennessee and expects it to be the largest of its kind in the country. The project broke ground a year ago and expects an annual production capacity of 60,000 tons. The lithium will be supplied by ExxonMobil.

“America needs secure domestic supply of critical minerals like lithium,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release. “ExxonMobil is proud to lead the way in establishing domestic lithium production, creating jobs, driving economic growth, and enhancing energy security here in the United States.”

The industry currently has a lithium supply shortage due to the material's use in electric vehicle batteries and the fact that most of production happens overseas.

“Building a lithium supply chain with ExxonMobil, one of the world’s largest energy companies, holds great significance,” Shin Hak-cheol, CEO of LG Chem, adds. “We will continue to strengthen LG Chem’s competitiveness in the global supply chain for critical minerals.”

Per the release, the final investment decision is still pending.

Earlier this year, Exxon entered into another energy transition partnership, teaming up with Japan’s Mitsubishi to potentially produce low-carbon ammonia and nearly carbon-free hydrogen at ExxonMobil’s facility in Baytown.

Last month, the company announced it had signed the biggest offshore carbon dioxide storage lease in the U.S. ExxonMobil says the more than 271,000-acre site, being leased from the Texas General Land Office, complements the onshore CO2 storage portfolio that it’s assembling.

3 Houstonians named to prestigious list of climate leaders

who's who

Three Houston executives — Andrew Chang, Tim Latimer, and Cindy Taff — have been named to Time magazine’s prestigious list of the 100 Most Influential Climate Leaders in Business for 2024.

As managing director of United Airlines Ventures, Chang is striving to reduce the airline’s emissions by promoting the use of sustainable aviation fuel (SAF). Jets contribute to about two percent of global emissions, according to the International Energy Agency.

In 2023, Chang guided the launch of the Sustainable Flight Fund, which invests in climate-enhancing innovations for the airline sector. The fund aims to boost production of SAF and make it an affordable alternative fuel, Time says.

Chang tells Time that he’d like to see passage of climate legislation that would elevate the renewable energy sector.

“One of the most crucial legislative actions we could see in the next year is a focus on faster permitting processes for renewable energy projects,” Chang says. “This, coupled with speeding up the interconnection queue for renewable assets, would significantly reduce the time it takes for clean energy to come online.”

At Fervo Energy, Latimer, who’s co-founder and CEO, is leading efforts to make geothermal power “a viable alternative to fossil fuels,” says Time.

Fervo recently received government approval for a geothermal power project in Utah that the company indicates could power two million homes. In addition, Fervo has teamed up with Google to power the tech giant’s energy-gobbling data centers.

In an interview with Time, Latimer echoes Chang in expressing a need for reforms in the clean energy industry.

“Addressing climate change is going to require us to build an unprecedented amount of infrastructure so we can replace the current fossil fuel-dominated systems with cleaner solutions,” says Latimer. “Right now, many of the solutions we need are stalled out by a convoluted permitting and regulatory system that doesn’t prioritize clean infrastructure.”

Taff, CEO of geothermal energy provider Sage Geosystems, oversees her company’s work to connect what could be the world’s first geopressured geothermal storage to the electric grid, according to Time. In August, Sage announced a deal with Facebook owner Meta to produce 150 megawatts of geothermal energy for the tech company’s data centers.

Asked which climate solution, other than geothermal, deserves more attention or funding, Taff cites pumped storage hydropower.

“While lithium-ion batteries get a lot of the spotlight, pumped storage hydropower offers long-duration energy storage that can provide stability to the grid for days, not just hours,” Taff tells Time. “By storing excess energy during times of low demand and releasing it when renewables like solar and wind are not producing, it can play a critical role in balancing the intermittent nature of renewables. Investing in pumped storage hydropower infrastructure could be a game-changer in achieving a reliable, clean energy future.”

Rice University researchers pioneer climatetech breakthroughs in clean water nanotechnology

tapping in

Researchers at Rice University are making cleaner water through the use of nanotech.

Decades of research have culminated in the creation of the Water Technologies Entrepreneurship and Research (WaTER) Institute launched in January 2024 and its new Rice PFAS Alternatives and Remediation Center (R-PARC).

“Access to safe drinking water is a major limiting factor to human capacity, and providing access to clean water has the potential to save more lives than doctors,” Rice’s George R. Brown Professor of Civil and Environmental Engineering Pedro Alvarez says in a news release.

The WaTER Institute has made advancements in clean water technology research and applications established during a 10-year period of Nanotechnology Enabled Water Treatment (NEWT), which was funded by the National Science Foundation. R-PARC will use the institutional investments, which include an array of PFAS-dedicated advanced analytical equipment.

Alvarez currently serves as director of NEWT and the WaTER Institute. He’s joined by researchers that include Michael Wong, Rice’s Tina and Sunit Patel Professor in Molecular Nanotechnology, chair and professor of chemical and biomolecular engineering and leader of the WaTER Institute’s public health research thrust, and James Tour, Rice’s T.T. and W.F. Chao Professor of Chemistry and professor of materials science and nanoengineering.

“We are the leaders in water technologies using nano,” adds Wong. “Things that we’ve discovered within the NEWT Center, we’ve already started to realize will be great for real-world applications.”

The NEWT center plans to equip over 200 students to address water safety issues, and assist/launch startups.

“Across the world, we’re seeing more serious contamination by emerging chemical and biological pollutants, and climate change is exacerbating freshwater scarcity with more frequent droughts and uncertainty about water resources,” Alvarez said in a news release. “The Rice WaTER Institute is growing research and alliances in the water domain that were built by our NEWT Center.”
