Malta product specifications and capabilities
■
Long Useful Life: Over 30 years without capacity degradation
■ Wide power range at high efficiency - System can operate from
<35% to 100% power at near constant efficiency
Environmentally friendly - all raw materials are fully recyclable and
abundantly available.
■ Rotating Inertia: Malta Turbomachinery derived from heavy-duty
GT and ST systems, significant rotational inertia in charge and
discharge modes:
■ Malta's charge powertrain Rotational Inertia: 799 MW s
■ Malta's generation powertrain Rotational Inertia: 684 MW s
■ Start time from "Ready to Start": <7 min to 25% load (charge and
discharge);
☐
Ramp rate: >15% per min (power ramp up or down)
