Two natural-gas pipelines with a total estimated cost of more than $3.5 billion received Federal Energy Regulatory Authority approval on Feb. 3. The 516- mile-long Sabal Trail Pipeline and the 126-mile Florida Southeast Connection pipeline will supply natural gas to new power plants in Florida, where gas is replacing coal as old power plants are demolished. Both pipelines are scheduled to be in service by spring 2017. Natural gas now fuels more than 60% of the state’s electricity.
