The voltage and frequency of a power grid is held in equilibrium by ensuring that the electricity produced equals the electricity demanded and there is sufficient inertia from power generators. The SMR-300 is right-sized to ensure that any one unit being out of service will not create a large grid disturbance. Further, the SMR-300 delivers constant, high-reliability power using proven pressurized water reactor (PWR) technology. Its large, synchronous generator contributes rotational inertia, helping to resist rapid changes in grid frequency. The reactor’s continuous thermal output and steady turbine operation ensure voltage regulation through consistent reactive power support. This stability makes the SMR-300 an ideal anchor for modern, renewables-heavy grids.
