Boca Raton – September 15, 2026 -- The national average price of diesel hit an all-time high of $5.85 a gallon on September 4, 2026, according to AAA, then climbed further to $5.9015 three days later, surpassing the previous record set in June 2022.
Diesel prices have risen more than 50% since the outbreak of war with Iran
A year ago the same gallon cost $3.71; on the eve of the conflict it cost $3.76. Six months of disrupted tanker traffic through the Strait of Hormuz and crude trading near $90 a barrel have added more than two dollars to a fuel that powers freight, agriculture, construction and a large share of the country's backup and off-grid electricity.
Fuel accounts for up to 80% of a diesel generator's lifetime operating cost
Industry estimates commonly place fuel at 70% to 80% of total lifetime operating cost for a diesel generator, meaning the purchase price is close to a rounding error against what an owner spends running the machine over its working life. A generator sized for peak demand that occurs only twice a day spends most of its hours burning diesel to produce electricity nobody is drawing, and that inefficiency now compounds against a fuel price that has risen by more than half in twelve months.
Global generator market grows toward $25.61 billion by 2031 as peak shaving expands fastest
MarketsandMarkets sizes the global diesel generator market at approximately $19.26 billion in 2026, projecting roughly $25.61 billion by 2031 at a compound annual growth rate of about 5.9%, according to a report summary published August 21, 2026. Grand View Research puts the 2026 figure at about $21.2 billion. The same MarketsandMarkets analysis identifies peak shaving as the fastest-growing application segment, at roughly 6.5% CAGR, and describes the category evolving toward hybrid-ready systems integrating battery storage to cut fuel use.
NOMAD Power Solutions targets a 75% diesel cut by pairing mobile batteries with generators
NOMAD Power Solutions, Inc. (Nasdaq: NMAD), headquartered in Boca Raton, Florida, operates truck-transportable, utility-grade battery energy storage systems sold, rented or delivered through Energy-as-a-Service contracts to utilities, industrial operators, government agencies and critical infrastructure providers. The company describes a configuration in which a mobile battery system is paired with a diesel generator so the generator runs intermittently to recharge the battery rather than continuously to supply load, a design it says targets roughly a 75% reduction in diesel consumption against a standalone generator. NOMAD states this is a design target, not a reported operating result.
The company's subsidiary, NOMAD Transportable Power Systems, Inc., holds United States patent number 12,391,084, granted August 19, 2025, covering transporters for utility-scale lithium-ion batteries, with a continuation application pending. NOMAD reached its current form in July 2026 when LIXTE Biotechnology Holdings, Inc. completed a merger with NOMAD Transportable Power Systems and adopted the NOMAD name; shares stopped trading under LIXT on July 2, 2026 and began trading under NMAD on July 6, 2026. Merger consideration included preferred stock convertible into approximately 50,366,070 common shares subject to stockholder approval, representing substantial potential dilution. NOMAD was added to the Russell Microcap Index in June 2026. Target customers include construction sites without grid access, telecommunications infrastructure, data centers, oil and gas and mining operations, ports and logistics facilities, and utility storm response.
Deploying a fleet of mobile storage assets is capital intensive and would require financing that has not been secured, and NOMAD competes against generator and rental operators many multiples its size, including Generac Holdings Inc., Cummins Inc., Caterpillar Inc. and United Rentals, Inc., several of which are developing their own hybrid and storage-integrated offerings.
