BrenX Ltd. (NASDAQ: BRNX) reported preliminary operating data from its flagship industrial project at Tempo Beverages in Israel indicating potential customer energy cost savings of approximately $1.0 million annually if current performance is sustained. The company's 32 MWh bGen™ thermal energy storage system is supplying steam at a cost about 40% below a modeled heavy fuel oil steam baseline, according to preliminary data reported on November 4, 2026.
For the five operating days from October 25 to 29, BrenX estimates net energy cost savings for Tempo were about $18,200, or about $3,640 per operating day. The annual estimate assumes 280 operating days a year and is net of annual maintenance costs. At that level, BrenX estimates Tempo could save approximately $15 million over 15 years. The system has also outperformed its base case, reaching approximately 85 tons of steam per operating day during commissioning, about 21% above the project's base case of approximately 70 tons.
The timing of the preliminary cost savings data works in BrenX's favor. In late October, the Dutch TTF benchmark for European natural gas rose above 100 euros per megawatt-hour, its highest level since 2022, according to Trading Economics. For European manufacturers that burn gas to produce steam, those prices flow directly into operating costs. One way to counter that is through electrification. Nearly 40% of fossil-fuel-based low- and medium-temperature industrial heat could be electrified cost-effectively, according to a recent report from the International Energy Agency, which pointed to thermal storage as an "increasingly promising" solution.
BrenX also developed a digital platform that gives Tempo live access to the system's steam output, electrical power, pressure and temperature, along with charging costs, energy savings and avoided carbon emissions. A built-in savings calculator lets users model results under different electricity tariffs. The company said that for a company introducing a new kind of industrial energy system, that transparency can help shorten the sales cycle.
Tempo is the first proof point in a broader strategy for BrenX, which rebranded from Brenmiller Energy in August. The company has expanded its focus to developing, owning, operating and optimizing energy assets that may combine local generation, electrical and thermal storage, grid connectivity and intelligent energy management. In Hungary, BrenX owns and is operating a 1.2 MWp solar facility in Kaposszekcső and has signed a definitive agreement to buy adjacent land for its planned first integrated energy resource center. In Israel, construction is underway on a 12 MWh bGen™ system at Wolfson Medical Center in Holon, designed to replace the hospital's fuel-oil boilers and expected to save approximately $1.5 million in annual energy costs.
The next milestone for investors is the completion of commissioning at Tempo and the start of commercial operations. After that, attention will turn to validating sustained operating performance and customer energy cost savings at Tempo, progress at Wolfson and new industrial customers in Europe.
