founder’s message

Our world is changing, and so is the way we power it. Over the past century, electricity has become the lifeblood of our homes, offices, and industries. It’s something we can’t imagine living without—yet it’s also something we can’t afford to take for granted.

When the 2001 energy crisis hit California, I saw an opportunity to help businesses take control of their energy costs. Solar PV quickly emerged as the clear solution—not just to reduce costs, but to eliminate them entirely. As a pioneer in commercial solar, we had to innovate from the ground up: designing racking systems, creating monitoring tools, and developing software to bring our vision to life.

Back then, solar was four times more expensive than it is today. To make it accessible, we pioneered financing solutions like Power Purchase Agreements (PPAs), enabling schools, municipalities, and private businesses to go solar with no upfront costs.

Today, we’re proud to offer solar systems with paybacks of less than three years—and still, no money down. The trends are clear: electricity prices keep rising, while solar costs keep falling. Even as government incentives phase out, solar remains a smart, sustainable investment.

At CitiGreen, we’re committed to staying at the forefront of distributed generation. We’re not just helping businesses and agencies save money—we’re helping them build a cleaner, greener future. It’s an industry we’re proud to be part of, and a legacy we’re honored to leave for generations to come.

Thank you for considering CitiGreen. Together, let’s power a brighter future.

Sincerely,
Mark Frederick
Founder and CEO
