Helping Businesses Make Smarter Energy Investments

For more than 24 years, CitiGreen has helped commercial property owners throughout Northern California reduce operating costs through practical energy solutions. From project evaluation and system design to construction and long-term support, we work with businesses to identify opportunities that deliver measurable financial value.

Our experience spans more than $140 million in completed commercial solar projects across a wide range of industries. Every project is evaluated based on energy usage, utility rates, site conditions, operational goals, and long-term economics to ensure the solution is the right fit for each customer.

As the energy industry continues to evolve, so does CitiGreen. In addition to commercial solar, we are expanding into battery energy storage, green hydrogen, and other technologies that help businesses prepare for the future while maximizing the value of their energy investments.

Our commitment has remained the same since 2009: deliver honest guidance, quality workmanship, and energy solutions that create lasting value for every client.

Technology will continue to change. Our commitment to helping customers make smart, long-term energy investments will not.

founder’s message

When I founded CitiGreen in 2003, my goal was simple: help businesses take control of one of their largest operating expenses, electricity.

Over the past two decades, we’ve watched the energy industry evolve through changing technologies, utility rates, government policies, and economic cycles. While the market has changed, our mission has remained the same: help our customers make informed energy investments that deliver long-term value.

Over the years, CitiGreen has completed more than $140 million in commercial solar projects throughout Northern California. We’ve worked with businesses, schools, agricultural operations, manufacturers, municipalities, and property owners, helping each customer find solutions that fit their operational and financial goals.

Today, the commercial energy market is entering another period of change. Solar remains an important solution for many businesses, but it is no longer the only one. Battery energy storage, distributed energy systems, and renewable hydrogen are creating new opportunities to improve reliability, reduce operating costs, and strengthen our energy infrastructure.

That is why CitiGreen continues to evolve alongside the industry. We remain committed to delivering practical, financially sound energy solutions while investing in the technologies that will shape the future of commercial energy.

Thank you for taking the time to learn about CitiGreen. We appreciate the opportunity to earn your trust and look forward to helping your business evaluate the right energy solution for years to come.

Sincerely,
Mark Frederick
Founder & CEO”
