First, let me say that I'm no fan of Ron DeSantis, our Statehouse, and their brand of politics. However, there are some arguments on the side of Florida Power & Light.
FP&L shut down its last coal-fired plant a couple of years ago. It now generates power by natural gas, nuclear, and solar. It also has one of the most ambitious programs of solar farm expansion in the U.S.
In urban areas, many residents live in dense gated and high-rise communities where there is little room for solar installations. (Due to its long rainy season and frequent cloud cover, Florida's sun index is only middling, meaning solar arrays have to be quite large to power a house fully.) This means a lot of solar arrays are installed in less dense areas, where miles of power lines are still required to cover relatively few users, including those users whose solar arrays do not cover 100% of their needs. These lines have to be installed and maintained even as the solar installations mean fewer paying customers per mile of transmission line.
Also, FP&L has to continue the heavy investment to provide gas- and nuclear-generated power to dense populations centers that will never be able to get enough power through at-residence solar arrays.
You could correctly argue that at-home solar arrays are a way for FP&L to get more solar array service into their grid. But when the extended solar grid cannot produce sufficient power during our long rainy spells, FP&L still has to maintain and operate gas- and nuclear-fired plants with sufficient capacity to replace the lost solar power. To keep rates down for the large Florida population that cannot get power from at-home solar, FP&L needs to keep as many paying customers on the grid as possible.
I think there are valid arguments on both sides of this issue. While FP&L obviously favors the side of the argument that best serves its interests, it is not exactly evil or rapacious to put that side forward.
