In this paper, we introduce a new simulation technique designed to\u0000address both challenges. It relies on the numerical inversion of the\u0000characteristic function, offering a general methodology applicable to all\u0000L'evy-driven OU processes. Moreover, leveraging FFT, the proposed methodology\u0000ensures fast and accurate simulations, providing a solid basis for the\u0000widespread adoption of these processes in the energy sector.
