PARRISH, Fla. (AP) — A key to the future of Florida’s power grid is a device that could be mistaken for a computer server.
This device is actually a drum module. Each of the components alone is as powerful as 2,000 iPhone batteries. But together, as a collection of tens of thousands of modules, they make up the world’s largest solar battery storage facility owned by the state’s largest utility, Florida Power & Light.
FPL’s Manatee Energy Storage Center is state-of-the-art solar energy technology in an evolving pastoral setting in fast-growing Southwest Florida.
At night or when there is heavy cloud cover overhead, the sun’s energy captured by the field of solar panels near the utility can be stored for later use, further reducing the need for depending on fossil fuels and allowing the excess renewable energy generated not to be wasted.
Battery storage can fill the electric solar vacuum on cloudy days, at night
Just as a rooftop solar contractor might advise a homeowner to install a battery in tandem with their solar system, battery storage is becoming an integral part of large-scale renewable energy investments.
“I think it’s safe to say that storage is a necessary component as we move toward more intermittent resources,” said Bryan Jacob, solar program director for the nonprofit Southern Alliance for Clean. Energy.
Battery storage can help bridge the gap between energy resources at times of day when solar power would be brought online and offline, Jacob said, or it can serve as a much-needed boost during peak times. use, such as when people go home after work.
When these large-scale solar investments were first made, “solar scaling was not yet a big issue,” Jacobs said, referring to the process in which renewable energy generation is reduced from its full potential due to supply and demand needs.
“So now you can absorb the excess generation of what would happen without having to reduce it,” he said.
FPL has over 500 megawatts of solar power storage, with the majority coming from the 409 megawatt Manatee Solar Power Center in Parrish. In 10 years, Juno Beach-based FPL hopes to increase its battery capacity sevenfold by adding an additional 3,200 megawatts of storage.
“You don’t need as many batteries (as solar power plants) because they don’t produce new energy, they just store it for later,” Silver said. “Long term, I think we’re going to start to see that there will be value for the batteries that will help meet the afternoon peaks and early morning peaks as we get more and more of solar energy on the system.”
FPL solar array located in a rural town with growing population
The Parrish facility, which began operations in December, is located on 40 acres off State Road 62 in unincorporated Manatee County, where single-family home developments are slowly taking over farmland as as Florida continues its rapid growth, in turn adding more consumers to the grid.
About 400 battery modules, each weighing more than 200 pounds and made by Samsung, are neatly stacked in each of the site’s 132 large metal containers. On the outside of each container is a warning: “DANGER. Lithium ion batteries. Risk of fire and explosion.
Each container can store about 7 megawatts, said Marcos Quintana, regional manager of FPL. This storage facility can supply 329,000 homes for two hours.
This collection of modules stores energy that comes mainly from the solar plant, which is about half a mile away as the crow flies.
“If in a pinch we need to charge quickly and solar power is not available, it is technically capable of charging from the grid,” said Matt Silver, project manager for FPL development. “But obviously we want to charge as much as possible from solar.”
The location of the FPL battery bears witness to the past, present and future of the utility
In the background of the solar panels and storage facility is one of FPL’s natural gas power plants, where two 1970s red and white striped chimneys tell this half-century-old story. century of Florida’s past and future, from fossil fuels to renewable energy.
These chimneys were to be taken out of service with the arrival of the solar battery installation, but they will now only be used if high electricity consumption in winter requires it, as part of FPL’s efforts to prepare for the conditions. extreme winter weather.
The 74.5 megawatt solar power plant, connected to the storage by buried cables, was commissioned in 2016 and is made up of more than 340,000 panels. A herd of cattle roams just outside the gate, while inside, feral hog traps help lure the notoriously destructive species to expensive equipment.
FPL has 30 megawatts of solar storage at two of its other solar sites in Suwannee and Columbia counties, and the utility has a number of smaller-scale pilot projects while exploring electric vehicle charging stations. Florida’s other major electric utilities, Tampa Electric Co. and Duke Energy, are also investing in battery storage.
“They’re really just one more tool in the toolbox,” Silver said. “Everyone is always looking for the quick fix or the magic wand that we will wave that will solve all your energy needs. But like anything else in life, it will likely be a variety of things that add up to solve our energy needs.
The batteries used in a solar energy system work as “accumulators” of energy and are responsible for storing the energy obtained by the solar panels. The function of the batteries is to provide electrical energy in the event of service interruptions or breakdowns due to emergency situations.
Why solar panels are not worth it?
Solar panels cannot store electricity, so you will have reduced power output on cloudy days and zero power output at night. For this reason, most residential solar systems require a solar battery. On the same subject : Why Biden extended tariffs on solar panels. You will need to consider this additional cost when deciding if solar panels are worth it for you.

What is a battery and how does it store energy?
A battery is a device that stores chemical energy and converts it into electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.

Batteries are devices used to store chemical energy that can be converted into useful, portable electrical energy. They allow free flow of electrons in the form of an electric current that can be used to power devices connected to the battery power source.
What is the purpose of storage in a hydro power plant?
Storage hydropower plants include a dam and reservoir to hold water, which is stored and released later when needed. Water stored in reservoirs provides the flexibility needed to generate electricity on demand and reduces dependence on variability in supply.
How does hydropower storage work? Pumped hydroelectric storage facilities store energy in the form of water in an upper reservoir, pumped from another reservoir at a lower elevation. During periods of high electricity demand, electricity is generated by releasing stored water through turbines in the same way as a conventional hydroelectric plant.
What is storage in hydroelectric power plant?
Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different altitudes that can generate power as water descends from one to the other (discharge), passing through a turbine.
What is the difference between storage and Pondage in a hydroelectric power plant?
Pond usually refers to the relatively small water storage behind the spillway of a run-of-river hydroelectric plant. Such a power plant has considerably less storage than the reservoirs of large dams and conventional hydroelectric plants which can store water for long periods such as a dry season or a year.
