SB 2315

This bill creates a special exemption for advanced nuclear reactors from certain cost-sharing requirements when connecting to the ERCOT (Texas) electrical transmission system. Specifically, it amends the Utilities Code to state that when interconnection costs exceed the normal transmission-owning utility allowance, advanced nuclear reactors (defined as fission-based reactors ranging from microreactors under 50 megawatts to large reactors up to 1,600 megawatts) will not be required to pay these excess costs, unlike other generation resources that must directly pay such overages. The exemption aims to reduce financial barriers for nuclear power development in Texas by shifting these excess interconnection costs away from nuclear developers, and would take effect September 1, 2025.
