Relating to certain cost sharing requirements for a desalination facility operating under a public-private partnership.

SB 448 requires private partners in new public-private partnership desalination projects to cover at least 50% of the facility's energy operating costs once it begins charging customers for water. This applies specifically to brackish water desalination facilities and only to contracts executed after the bill's effective date of September 1, 2025. Existing agreements that started charging customers before this date remain governed by prior law. The bill directly affects private entities operating such facilities under new contracts, ensuring they bear a significant share of ongoing energy expenses. It does not change cost-sharing for facilities already operational under older agreements.
