The power plant meets some very high requirements for power supply regularity, since a power supply interruption of more than a few hours may result in severe damage to the aluminium production process. The power plant design therefore includes spare capacity in the form of one generator unit with additional back-up from the national grid.
Gas and steam turbines
The configuration includes four gas turbines and two steam turbines operating in a combined cycle. Total installed capacity is approximately 1,350 MW. The design is based on best available technology (BAT); i.e. low NOx burner technology, in combination with selective catalytic reduction (SCR), complying with local emission standards. Furthermore, the cooling tower system minimizes the plant’s total cooling water requirement.
