Florida counties pause data center development, state addresses concerns
More than a dozen Florida counties have paused new data center applications due to concerns over energy, water, and noise. Florida has enacted Senate Bill 484 to preserve local land-use authority, require full cost of service charges from utilities, and favor reclaimed water for facilities over 50 megawatts. The article emphasizes designing data centers as quiet, water-conscious, and storm-resilient energy systems that serve local communities.
Issa Batarseh, a Pegasus Professor of Electrical Engineering at the University of Central Florida, highlighted the comprehensive impact of data center development in Florida, noting that over a dozen counties have paused new data center applications to draft new regulations. He clarified that modern data centers, particularly those for AI, are industrial energy systems that demand massive power, generating significant heat and posing grid stability challenges due to pulsating power loads.
Batarseh also detailed the substantial water consumption of large data center campuses, which can range from one to five million gallons daily if using evaporative cooling, comparable to a small town's needs. He questioned the source of water, advocating for reclaimed water over potable. Noise pollution from cooling fans and backup generators was another key concern, for which he recommended enforceable limits. Batarseh argued that the enduring value of data centers for local communities comes not just from direct employment but from fostering innovation, research, and new companies, provided that agreements are structured to facilitate these benefits.
In response to these issues, Florida enacted Senate Bill 484, effective July 1. This legislation preserves local land-use authority for data centers exceeding 50 megawatts, mandates utilities to charge these facilities the full cost of service, promotes the use of reclaimed water, and commissions an independent study. Utilities are now required to submit their large-load tariffs to the Public Service Commission by October 1. Batarseh urged counties to proactively plan for data centers as integrated, sustainable energy systems rather than merely power consumers.
