Other Events.

On April 2, 2024, Tampa Electric Company (the “Company”) filed with the Florida Public Service Commission (the “FPSC”) a request for a base rate increase, effective January 1, 2025, and additional adjustments for 2026 and 2027. The Company’s proposed rate request included recovery of solar generation projects, energy storage capacity, a more resilient and modernized energy control center, and other resiliency and reliability projects. Prior to the rate case hearing, the Company submitted revisions to its requested base rate increase to reflect items that included production tax credits, energy storage life expectancy, and the Company’s grid reliability and resilience project. From August 26 through 30, 2024, the Company’s rate case hearing was heard by the FPSC. On December 3, 2024, the FPSC rendered a decision during a Special Agenda Conference. The FPSC decision includes an increase of $185 million in 2025 and additional increases of $87 million and $9 million in 2026 and 2027, respectively. The decision also allowed for equity in the capital structure to continue to be 54% from investor sources of capital. The allowed regulatory return on equity range is 9.50% to 11.50% with a 10.50% midpoint, effective January 1, 2025. Final rate details reflecting this decision are expected to be determined by the FPSC on December 19, 2024.
