Company's WETA Ionization Technology Begins Operations in Gill, Colorado, Marking State's First Warm Weather Modification Program

NAPLES, FL / ACCESS Newswire / November 11, 2025 / Rain Enhancement Technologies Holdco, Inc. (NASDAQ: RAIN) ("RAIN" or the "Company"), a leading provider of ionization rainfall generation technology, today announced it has commenced operations of its first U.S. installation following approval of a Weather Modification Permit from the State of Colorado's Water Conservation Board. The Company's Weather Enhancement Technology Array (WETA) system, installed in Gill, Colorado, in October 2025, marks the state's first warm weather modification program and is now operational under a permit valid through October 31, 2026, with the potential for a five-year renewal. The installation can enhance up to 360 square miles of agricultural land in Weld County, where the technology has the potential to increase rainfall by 15-18% based on peer-reviewed trials.

"This first U.S. installation represents a transformative milestone for Rain Enhancement Technologies as we bring our proven ionization technology to American agricultural communities," said Randy Seidl, CEO of Rain Enhancement Technologies. "Colorado's rigorous evaluation process and forward-thinking approach to water resource management validate the potential of our technology to address water scarcity challenges. We're proud to pioneer the state's first warm weather modification program at a time when innovative water solutions are critically needed."

The ground-based WETA system operates by using electrical charge to create naturally occurring ionized aerosols, which then travel to cloud layers where they enhance condensation and stimulate precipitation. Unlike Colorado's traditional cold weather cloud seeding that uses silver iodide, RAIN's chemical-free, solar-powered approach harnesses natural atmospheric processes.

"After years of working with this groundbreaking technology internationally, it's very exciting to see the growing interest in our solution to address the ongoing water shortage crisis," said Scott Morris, Chief Technical Officer of Rain Enhancement Technologies. "With the first of our US installations to be deployed, we're excited to demonstrate the real-world impact of ionization rainfall generation technology at scale. The Gill installation represents years of engineering refinement and will operate autonomously using solar power, making it both environmentally sustainable and cost-effective."

This marks Colorado's first warm weather seeding operation, differentiating it from existing cold weather programs in the state that use silver iodide to enhance snowpack. RAIN's ionization technology has demonstrated effectiveness in warm weather conditions through international deployments, including a six-year trial in Oman's Hajar Mountains, where results were published by the Royal Statistical Society showing statistically significant rainfall increases. The Colorado installation operates under strict regulatory oversight, including automatic suspension protocols during National Weather Service severe weather warnings, real-time weather monitoring capabilities, and coordination with local emergency management officials.

"We're encouraged by the potential of this innovative technology to supplement water resources for Colorado's agricultural communities," said Andrew Rickert, Weather Modification Program Manager with the Colorado Water Conservation Board. "This program will provide valuable data on warm weather modification effectiveness while maintaining our rigorous safety and environmental standards. Rain Enhancement Technologies' approach represents a new tool in our comprehensive water management strategy."

The Colorado installation comes as western U.S. agriculture faces persistent drought conditions that have forced farmers to fallow fields, reduce livestock herds, and seek innovative water security solutions. Colorado's agricultural sector, which consumes approximately 80% of the state's developed water supply, continues to experience pressure from reduced water allocations and climate variability. The WETA system's coverage area can enhance up to 360 square miles, encompassing 230,000 acres of agricultural land that could benefit from enhanced precipitation.

As part of the permit requirements, RAIN will conduct annual target-control evaluations, submit periodic performance reports to project sponsors, and provide detailed annual reports to the Colorado Water Conservation Board. The solar-powered system operates autonomously with minimal maintenance requirements and produces no environmental residue through its chemical-free ionization process.
