Florida’s Commission Staff on Grid Hardening (Video)
In the latest video from Public Utilities Fortnightly, utility regulation expert Tom Ballinger explores how the Florida Public Service Commission is responding to the challenges of frequent and severe storms.
A 2018 report analyzing data from tropical storms in 2016 and 2017 found that the state’s “aggressive storm hardening programs were working.” The report also examined the performance of hardening efforts across the state, including overhead lines vs. underground lines and concrete poles vs. wooden ones.
The Commission used forensic data gathered after the storms to analyze the impact selective undergrounding has on resilience. Even with varied storm conditions across the state, the report found that underground distribution feeders generally performed better than non-hardened and hardened overhead distribution feeders during hurricane Irma.
Hardening Florida’s electricity system is now taking the next step. Ballinger mentions the uptick in undergrounding pilot projects including ones from Duke Energy and Florida Power & Light (FPL).
