The bill (HB 741) dealt with a somewhat-wonky issue known as "net metering." But it drew a fierce debate during this year's legislative session, as supporters said the state needed to end subsidies for people with rooftop-solar systems and opponents contended the measure would cripple the rooftop-solar industry.

DeSantis' veto message focused on part of the bill that dealt with the potential that more property owners than expected would install rooftop-solar systems between July 1, 2022, and Dec. 31, 2023 — before key changes in the bill would start to take effect in 2024.

If such higher-than-expected rooftop solar use occurred during the 18-month period, utilities would have been allowed to seek to recoup lost revenues from their broader customer bases. The veto message said the "amount that may be recovered under this provision is speculative and would be borne by all customers."

"Given that the United States is experiencing its worst inflation in 40 years and that consumers have seen steep increases in the price of gas and groceries, as well as escalating bills, the state of Florida should not contribute to the financial crunch that our citizens are experiencing," DeSantis' veto message said.

Opponents of the bill quickly praised the veto, saying it would help efforts to boost renewable energy.

"We applaud Gov. DeSantis' decision to veto this bad bill and be a champion for #solar jobs," the Florida Wildlife Federation said in a Twitter post. "We must continue to work together to increase access to solar and other #renewableenergy resources to combat the climate crisis and provide Floridians with affordable energy solutions."

Net metering is a system that deals with the interplay between utilities and rooftop-solar owners, including credits that utilities provide for electricity generated by rooftop systems.

Rooftop-solar owners are required to hook up to utility systems and are able to sell excess electricity and receive bill credits in return. Under rules approved in 2008 by the Florida Public Service Commission, monthly credits are provided at utilities' retail rates. An important part of the bill would have changed that to ultimately providing the credits at what are known as "full avoided cost" rates, which would reduce the amounts going to rooftop-solar owners.

Supporters of the bill, which would have been phased in over several years, said changes are needed because utilities continue to face the overall costs of operating the electrical grid. They said the current system of rooftop-solar credits has shifted more overall utility costs to people who do not have solar systems.

During a March 7 debate, Senate bill sponsor Jennifer Bradley, R-Fleming Island, said the current system is "regressive," as it leads to the vast majority of utility customers subsidizing rooftop-solar owners.

"This bill is fair," Bradley said. "It's a thoughtful glide path to get us to a no-subsidy (system)."

The bill had backing from Florida Power & Light, which ran television ads urging lawmakers to pass it. FPL said in a statement after the veto that it is "always working to deliver clean, reliable energy while keeping customer bills affordable."

"We remain committed to finding a more equitable net metering solution for all Floridians," the statement said. "FPL is leading the nation's largest solar expansion and we will continue to advance solar that is cost-effective for all our customers."

But the bill faced a massive outcry during the legislative session from the rooftop-solar industry and environmental groups.

The opponents argued it would take away financial incentives for property owners to install rooftop systems. That, they said, would hurt the rooftop-solar industry, while also dealing a blow to increasing the use of renewable energy.

"Thanks to @GovRonDeSantis for vetoing HB741 Net Metering this PM! This harmful bill would have had a chilling effect on FL's rooftop #solar industry when it is still in its infancy," Julie Wraithmell, executive director of Audubon Florida tweeted Wednesday. "Great news for renewables, consumers + meeting the challenge of climate change in FL."
