The agreement helps secure 528 jobs at the facility, along with associated economic benefits to the local and regional economy.

The new contract provides Alcoa with up to 320MW of power at the Industrial Power (IP) rate and will allow the plant to produce a total of 184kt/y.

Direct power sales were halted in 2006. The new contract has two phases – an immediate 17-month power supply for up to 320MW and a second phase for at least an additional five years of power.

The second phase would be implemented following clarification of a recent US 9th Circuit Court of Appeals ruling and will depend on the state of future power markets.

Under terms of the agreement, the facility will maintain an average of 528 full-time equivalent jobs.
