Modula S is an Army xTech SBIR Phase 2 winner for contested logistics and expeditionary basing in the INDOPACOM AOR. In 2026, we will be testing and collecting data during Army exercises in the Pacific. Modula S hypothesizes that managing power consumption is far more efficient than managing power production. Typically, reducing demand is considered the answer to improving efficiency; however, by managing consumption, we achieve the next level of energy efficiency. The objective is to reduce liquid fuel consumption when supply chains are both at risk and/or disrupted. Modula S is building and testing an integrated power system where: -Generators only run at full speed, their most efficient setting. -Generators are half the size of comparable generators for the same continuous load. -Generators are one-third the size of comparable generators for short-term spike loads. -The power system uses Sodium-Ion Batteries, Ultra-fast recharge and discharge, Lifespan exceeding 50,000 cycles, Nonflammable, and can be safely shipped. -The inverters, which draw power from the batteries, provide a variable power load for consumption. -The power management system is a scalable Building Automation System (BAS). The BAS matches up with and controls variable-speed heat pumps for HVAC.
