Fresno's New Solar System Cuts Energy Costs by $122M

The City of Fresno just flipped the switch on a solar system that's rewriting the rules for affordable clean energy.

ForeFront Power completed its first Earth Mount Solar system at Fresno's Northeast Surface Water Treatment Plant in March 2026, using technology from Erthos that mounts panels directly on the ground instead of on expensive steel racks. The result? Massive cost savings passed directly to residents through lower electricity rates for the next 20 years.

The timing couldn't have been better. When ForeFront Power started planning in 2023, inflation and supply chain chaos had sent steel and labor costs soaring. Project manager Erinne Davis and her team realized a traditional system would be too expensive, threatening the entire project.

That's when they discovered Erthos technology. By eliminating steel racks entirely and placing panels flat on the earth, they avoided costly construction upgrades and passed the savings straight to Fresno ratepayers.

The numbers tell an incredible story. This system is part of a three-site portfolio totaling 27 megawatts that's expected to save Fresno residents over $122 million by 2045. Since going live, the system has consistently beaten expectations, operating at 101% of predicted energy production and already delivering 862 megawatt-hours of clean electricity.

The innovation doesn't stop at installation. The flat panels can follow ground contours up to 15% slope, adapting naturally to the landscape. They pack more generating capacity per acre than traditional systems because there's no spacing needed between rows.

Even maintenance got an upgrade. Autonomous robots called ErthBots clean the panels nightly using dry nylon brushes, then return to their charging docks automatically. Each robot handles over 3.5 megawatts of panels, making it the most cost-effective cleaning method in the industry.

The Ripple Effect

Fresno's success is already inspiring other cities and developers looking to make solar more affordable. By proving that innovative design can dramatically cut costs without sacrificing performance, this project opens doors for communities that previously couldn't justify solar investments.

The partnership between ForeFront Power and Erthos shows what happens when companies prioritize problem-solving over convention. They faced a challenge that could have killed the project and instead found a solution that delivers better results for less money.

Both organizations continue working together to optimize the system's performance, encouraged by the strong early results. CEO Jim Tyler of Erthos sees this as proof that Earth Mount Solar can unlock projects previously blocked by high construction costs.

Clean energy just got more accessible, and Fresno residents will enjoy the benefits for decades to come.
