The IESO will continue its leadership in implementing the government’s green energy policy, and in facilitating innovations in the way the province’s bulk power system is operated, with an ongoing focus on reliability and efficiency. The changes underway are the most significant in the 100-plus- year history of the province’s electricity industry. Given its interdependencies, the power system will be continuously reconfigured over the next decade as coal plants are shut down, new gas plants are commissioned, nuclear units are refurbished and returned to service, unprecedented amounts of renewable generation are integrated into the system, the transmission system is renewed, improved.
