Imagine a solution that could simultaneously address Utah’s ongoing water crisis while contributing to the state's energy needs—sounds almost too good to be true, right? But here’s where it gets controversial: could deploying floating solar panels on lakes and reservoirs truly help preserve water levels and provide cleaner electricity? And this is the part most people miss—such innovative ideas often spark heated debates about practicality, environmental impact, and long-term sustainability.
Recently, a fresh concept gained attention on Utah’s Capitol Hill, blending water conservation with renewable energy generation. Representative Hoang Nguyen from Salt Lake City, along with local company Water Wise Solar Solutions, proposed the idea of installing floating solar panels across Utah’s water bodies. These panels could serve a dual purpose: shielding water surfaces from the intense summer heat to reduce evaporation and generating electricity to help meet the state’s growing energy demands.
Nguyen expressed personal interest in the idea during a legislative committee meeting, emphasizing the need for inventive thinking in tackling resource challenges. While no formal legislation has yet been introduced to push forward this plan, the concept resonated across party lines, sparking genuine bipartisan curiosity among commission members.
Utah faces severe drought conditions, with both the Great Salt Lake and Lake Powell shrinking to historic lows due to prolonged dryness and excessive water use. At the same time, the rising demand for artificial intelligence, data centers, and electric transportation puts additional strain on Utah’s power grid. Experts from Water Wise Solar Solutions pointed out that nearly three million acre-feet of water evaporate each year from the Great Salt Lake alone, with reservoirs across the state losing about a million acre-feet collectively.
Their goal isn’t only to conserve water through shade but also to ease land use pressures that often come with large-scale solar farms elsewhere. For example, there are already installations of floating solar arrays on storage ponds in California and New Jersey, and near Park City, a project designed to prevent algal blooms by powering water treatment processes. These projects demonstrate how floating solar can be effectively integrated into existing infrastructure, and the potential to expand to larger reservoirs in Utah isn’t far-fetched.
Pairing floating solar with existing hydropower infrastructure could be especially strategic—improving energy output while safeguarding vital water resources. Representatives expressed hope that legislative support could facilitate collaborations with federal agencies, such as the Bureau of Reclamation, to implement these projects more smoothly.
The most ambitious vision involves placing solar panels on Utah Lake and the Great Salt Lake themselves—massive projects capable of generating up to one gigawatt of power. While acknowledging the logistical and ecological challenges, such as protecting local wildlife and avoiding disruption to migrating bird populations, advocates see these as the prime targets for large-scale innovation.
Governor Spencer Cox has championed a broad energy strategy called 'Operation Gigawatt,' aiming to more than double the state’s power output within the next decade. His approach is described as an 'all-of-the-above' plan, combining traditional energy sources with these cutting-edge solutions.
However, concerns aren’t absent. Some lawmakers worry about the impact on local bird populations—Utah’s Great Salt Lake sees over twelve million bird visits annually from more than 300 species relying on its unique food chain of brine flies and shrimp. Floating solar panels could, in theory, provide nesting opportunities according to some research, but they might also pose risks, such as interfering with critical habitats or recreational activities like boating and water skiing.
For instance, on larger reservoirs like Pineview and Willard Bay, floating arrays might hinder water-based recreation and require strategic planning to avoid disrupting local economies. Water managers suggest that small, carefully designed projects could be implemented without significant obstacle, but larger-scale installations must consider maintenance and operational challenges.
There’s also skepticism about placing panels over irrigation canals. Experts emphasize the importance of engaging public utilities in the decision-making process to ensure such projects are financially viable. The potential economic benefits, however, could be significant—if the value of water savings and energy produced outweigh the costs.
Furthermore, floating solar can contribute positively by reducing water temperatures, fostering healthier aquatic habitats. Yet, recent studies raise questions about ecological impacts, noting that effects on aquatic life are still largely uncertain and vary depending on specific conditions like water depth and circulation.
Lynn de Freitas, director of FRIENDS of Great Salt Lake, voiced caution regarding the idea of installing floating solar panels on the massive, hypersaline lake. She highlighted concerns about infrastructure durability, given the lake’s corrosive environment and frequent wave action that could compromise equipment and escalate maintenance costs.
While innovative, the proposal to harness floating solar on Utah’s iconic water bodies presents a complex mix of opportunities and challenges. It prompts us to ask—should we prioritize environmental preservation over energy development, or is there a way to strike a sustainable balance? What do you think—would floating solar panels be a viable and responsible solution for Utah’s water and power issues? Or are the risks outweighing the benefits?
