AI data centers need a lot of power to run servers, cooling systems, and other equipment. As more large users seek service, Florida utilities are planning for higher demand and the infrastructure needed to support it.
Florida has also updated how utilities handle very large electricity customers. A new state law requires public utilities to file large-load tariffs designed to make qualifying customers responsible for the cost of serving their demand.
For other Florida businesses, the bigger question is what they can control. Commercial solar is one option.
Key takeaways
- Data centers are one of several large electricity users driving Florida’s rising power demand.
- Florida now has new rules for how large-load customers pay for the costs of serving them.
- On October 1, 2026, FPL told the Florida Public Service Commission (PSC) how its large-load rates meet the new law.
- Commercial solar can let a business generate part of its power on site.
Depending on the financing structure, solar can make part of an energy budget easier to plan.
Why are data centers getting all the attention?
Data centers can have very large power needs because their servers and cooling equipment can operate for long periods.
Florida law now defines a large-load customer as one with an expected monthly peak load of 50 megawatts or more at one location.
When a large project connects to the grid, the utility has to consider the generation, transmission, connection, and other infrastructure needed to serve it.
Data centers are not the only factor affecting electricity costs. Fuel prices, utility rates, demand charges, and a company’s own energy use also matter.
What is changing in Florida?
Under the law, large-load customers must pay the full cost of their service.
FPL filed with the PSC on October 1, 2026, saying its existing large-load rates meet the new state requirements. Under FPL’s rates, qualifying data centers must fund 100% of the new generation needed for their projects.
What can your business control?
You can’t control utility rates or how much power other large customers use.
You can review your own energy use and decide whether generating some power on site makes sense.
You can install solar panels on a suitable roof or open ground. When they produce power, your business can use it right away. This means you buy less power from the grid.
Can solar make energy costs more predictable?
No one knows what utility rates will be years from now. Solar can make the cost of your electricity more predictable.
Many solar financing plans offer a flat monthly payment, making that portion simple to budget for. You will still have a utility bill, but the amount will depend on your system and usage.
Check your bills first
Look at your recent utility bills and your property. Check:
- Monthly energy use.
- Periods where energy usage spikes.
- Peak demand and energy costs.
- Current tariffs set by your utility company.
- Space available on the roof or ground.
- Shade and sunlight
- Future energy needs
- Project and financing costs
This helps you see if solar is a good fit for your business.
Does solar mean leaving the grid?
No. Commercial solar works alongside your existing utility service.
You use solar power when your panels are producing energy and grid power when you need more.
What can Florida businesses do now?
A site assessment checks available space, sunlight, electrical needs, and other project factors. Book a free site assessment with Tampa Bay Solar to see if solar is right for your business.
FAQ
Are data centers increasing electricity demand in Florida?
Yes. They are one of several large electricity users driving demand growth.
Are Florida utilities changing how large-load customers pay for electricity?
Yes. New rules require qualifying large-load customers to bear their own cost of service.
Can commercial solar reduce the amount of electricity a business buys?
Yes. Your panels produce power, so you buy less electricity from the utility.
Can solar make energy costs more predictable?
Yes. Part of your energy cost comes from your solar system, not future utility rate increases.
What should a business check before installing commercial solar?
Review recent bills, energy use, utility rates, available space, and sunlight.
