Solar power and battery storage are saving Texans hundreds of millions of dollars on their electric bills, the president and CEO of the Solar Energy Industries Association recently told a congressional committee.

Abigail Ross Hopper, the association’s president and CEO, said in testimony given to the U.S. Senate Environment and Public Works Committee that states like Texas that are adding significant capacity for solar power and battery storage are enjoying lower, more stable prices for electricity.

“Unsubsidized solar is now the cheapest source of electricity in history in much of the country,” Hopper said. “With no fuel costs, solar provides a hedge against natural gas price volatility that continues to cause electricity price spikes.”

“The only way to put downward pressure on prices is by bringing more power online, not less,” she added.

To illustrate the value of solar power and battery storage, Hopper compared two hot summer days in Texas—one in July 2022 and the other in July 2025.

Hopper explained that the Electric Reliability Council of Texas (ERCOT) had begun installing solar on its grid in 2022 but had very little battery storage. ERCOT manages 90 percent of the state’s electrical load.

When ERCOT grid conditions buckled under high demand on the highlighted day in 2022, the price of electricity spiked to nearly $1,500 per megawatt-hour, Hopper said.

“Three years later, the amount of solar had increased substantially and was complemented by energy storage,” she said.

On the specified day in 2025, under even greater demand than three years earlier, sizable amounts of solar power, battery storage and wind power kept ERCOT’s midday price of electricity low and stable—around $50 per megawatt-hour. That dollar amount represented a nearly 100 percent decrease compared with the highlighted day in 2022.

Solar and wind supplied nearly 40 percent of Texas’ power during the first nine months of 2025, according to the U.S. Energy Information Administration (EIA).

Despite the state’s expansion of solar power and battery storage capacity, residential electricity prices in ERCOT’s territory rose 30 percent from 2020 to 2025 and are expected to climb another 29 percent from 2025 to 2030, according to a forecast from the Texas Energy Poverty Research Institute.

The increase in electric bills is tied to factors such as:

Higher natural gas prices
Greater demand from AI data centers and cryptomining facilities
Extreme weather
Population growth
Development of new transmission and distribution lines

The strain on ERCOT’s grid is only getting worse. An EIA forecast predicts demand for ERCOT electricity will jump 9.6 percent in 2026, and ERCOT expects a 50 percent jump in demand by 2029.

Kanin Energy raises up to $100M for waste-heat-to-power projects

fresh funding

Kanin Energy, a member of the Greentown Labs climatech and energy incubator in Houston, recently raised as much as $100 million in capital to grow its energy-as-a-service platform.

S2G Investments led a round of up to $50 million, and the Canada Growth Fund chipped in an additional $50 million. The money will primarily support Kanin’s development and operation of waste-heat-to-power projects.

Kanin—founded in 2020 in Calgary, Alberta, Canada—builds and runs onsite power assets for large-scale energy users. The startup says its energy-as-a-service offering lowers power costs, boosts power reliability and decreases emissions.

The company operates a waste-heat-to-power project at Ohio’s University of Dayton. The project supplies zero-emission electricity.

Kanin has a pipeline of projects totaling about 50 megawatts of capacity. This includes a waste-heat-to-power plant at the Phillips 66 Mewbourn gas-processing plant near Greeley, Colorado.

“Kanin was built on the belief that industrial facilities already hold the solution to their own energy challenges, they just need the right partner to execute,” Janice Tran, CEO of Kanin, who is based in Houston, said in a release. “At a time when power costs continue to rise, [our] solutions are an important tool for our industrial customers to manage their costs, operations, and emissions.”

Marisa Sweeney, principal at S2G, says waste heat is a largely underused resource for lowering power costs, alleviating grid congestion and improving power reliability.

The waste-heat-to-power process captures thermal energy from industrial activities and converts it to electricity. This happens without using extra fuel or generating more emissions.

Kanin says up to 58 percent of energy consumed by industrial processes is lost as waste heat. This heat winds up in the atmosphere at thousands of facilities in North America, including oil-and-gas operations, cement plants, and steel mills, the startup says.

Kanin was founded in 2020 in Calgary, Alberta, Canada. It opened offices at Greentown Labs Houston in July 2022.

7 Houstonians from energy sector make Forbes list of richest Americans

Rich List

The richest billionaires in America have a collective worth of $8 trillion in 2026, a staggering $1.4 trillion increase since last year, says Forbes. American billionaires are so wealthy that it now takes an unprecedented $4.4 billion net worth to be considered one of the richest people in the country. And one local billionaire has regained the title as Houston's wealthiest resident.

The annual Forbes 400 list is a definitive ranking of the wealthiest Americans, using interviews, financial data, and documentation provided by billionaires and their companies. In all, 43 billionaires across Texas made it on the 2026 list, and 10 are based in Houston. Seven of them have ties to the energy industry.

Oil tycoon Jeffery Hildebrand, 67, now reigns as the No. 1 richest Houstonian, the 9th richest Texan, and the 88th richest person in America for 2026. Hildebrand's net worth has surged $4.7 billion since last year, bringing his current net worth to $14.7 billion. He cofounded Hilcorp, one of the largest privately owned oil and natural gas producers in the U.S., in 1990 and served as its CEO until 2018. He still serves as the chairman of the company.

Kinder Morgan chairman Richard Kinder is the No. 2 richest in Houston. Kinder, 81, was dubbed Houston's richest billionaire in the 2025 Forbes 400 list. His net worth has increased from $11.1 billion to $12.9 billion in just one year. He is the 11th richest Texan and the 100th richest person in America.

Houston pipeline heir Randa Duncan Williams ranks 124th on the list with an estimated net worth of $11.7 billion. Fellow pipeline heirs Dannine Avara and Milane Frantz tie for 128th nationally. Each has an estimated net worth of $11.6 billion. Scott Duncan ties for No. 137 with an $11.3 billion estimated net worth.

Energy exploration chief executive George Bishop of GeoSothern Energy ranks No. 380 with an estimated net worth of $4.5 billion. Last year: $4.7 billion.

Here's how the rest of Houston's billionaires, outside of the energy industry, ranked on this year's list:

Toyota mega-dealer Dan Friedkin, 61, is the 102nd richest American with an estimated net worth of $12.9 billion, up from $9.7 billion last year. He most notably owns Gulf States Toyota, which sold $14.5 billion worth of Toyotas in 2025, per Forbes.
Hospitality honcho Tilman Fertitta, 69, has a net worth of $12.3 billion and is the 110th richest American. Fertitta owns hospitality corporation Fertitta Entertainment and the NBA team Houston Rockets. He most recently purchased the WNBA's Connecticut Sun and plans to relocate them to Houston under the Houston Comets name in 2027. He also keeps himself busy as President Trump's ambassador to Italy.
