A federal appeals court has ruled that Kansas residents cannot use state consumer protection laws to sue natural gas wholesalers over extraordinary price increases that occurred during a severe winter storm in February 2021. The 10th Circuit Court of Appeals upheld a lower court’s dismissal of five consolidated class action lawsuits on Monday, determining that federal law takes precedence over state claims in this matter.
The lawsuits stemmed from Winter Storm Uri, which brought record-breaking cold temperatures to the Southern Plains region. The extreme weather event not only drove up demand for natural gas but also caused operational failures at wellheads throughout the area, creating a perfect storm for price volatility.
During the crisis, wholesale natural gas prices on the spot market experienced unprecedented increases. According to court documents, the benchmark price tracked by S&P Global’s Platts market index skyrocketed from $2.545 per million British thermal units on February 1, 2021, to $622.785 per million British thermal units by February 17 – representing a staggering 200-fold increase.
The three-judge appellate panel unanimously concluded that the Natural Gas Act, which grants the Federal Energy Regulatory Commission exclusive authority over interstate wholesale gas transactions, prevents state-level consumer protection claims. Circuit Judge Harris Hartz, writing for the panel, stated that regardless of how the plaintiffs framed their arguments, their lawsuit targeted interstate wholesale transactions and practices that fall squarely within federal jurisdiction.
The Kansas Corporation Commission, which regulates intrastate and retail natural gas sales within the state, had ordered local distributors to take all necessary steps to meet consumer demand during the emergency. This directive forced distributors to purchase gas at the inflated spot market prices, with these costs ultimately being passed on to consumers through rate adjustments spread over several years.
Following the storm, the Federal Energy Regulatory Commission’s Office of Enforcement conducted an investigation into wholesale transactions to determine whether market manipulation or other misconduct had occurred. The investigation concluded without any enforcement actions being taken against the wholesalers.
The winter storm’s impact extended far beyond Kansas, affecting a broad swath of the southern and central United States. Texas bore the brunt of the disaster, experiencing a catastrophic power grid failure that left millions without electricity and resulted in 246 deaths. Weather officials designated it as the costliest weather disaster in Texas history.
U.S. District Judge Daniel D. Crabtree had initially dismissed the cases in 2023, acknowledging the severe price increases but maintaining that Congress had assigned regulatory authority over gas transportation and sales to federal agencies, not state courts. The judge noted the inverse relationship between plummeting temperatures and soaring gas prices during the crisis.
The litigation emerged as Kansas residents began seeing increased bills in summer 2023, when deferred costs from the storm started appearing on consumer statements. While initial cases were filed in both state and federal courts beginning in 2021, the consolidated cases before Judge Crabtree arrived in late 2023 and early 2024.
Sam Walenz, representing the consumers, expressed disappointment with the ruling while indicating that legal teams are reviewing the decision to determine potential next steps. The appellate panel included Chief Circuit Judge Jerome Holmes and U.S. District Judge Matthew Garcia, who sat by designation.
