Origin Energy has announced a AUD230 million (US$173.4 million) plan to expand the project to a generation capacity of 500 MW, which would power an additional 80,000 homes. Two options for the expansion are currently being studied, including building a new station next to the current Kangaroo Valley station, which would add 160 MW of pump storage. The second (preferred) option is to bypass the Kangaroo Valley power station by building an underground station that would use water from the Fitzroy Falls reservoir, which would increase capacity by 235 MW
