Power producers with plants based on ALSTOM Power's sequential combustion gas turbines enjoy significant inherent advantages.

Individually controlled combustion chambers enable GT24 and GT26 based combined cycle plants to maintain unrivaled efficiencies throughout the whole load range. At 50% load, they're approximately 15% more efficient than similar plants using conventional gas turbines.
