Adding batteries to the power plant give you the benefits of: Spinning reserve Energy Storage system is connected and running, but not charging or discharging energy into the system. On loss of generating capacity it steps in to take the load for a predefined period of time.

Peak shaving Energy Storage system absorbs load variations in the network so that engines only see the average load.

Enhanced Dynamic Performance Energy Storage system absorbs sudden load changes and then ramps the change over on running engines.

Strategic Loading Energy Storage system interacts with the power system to optimize engine fuel efficiency.

Zero Emission Operation Energy Storage system powers the system so that engines can be turned off. This enables things like zero-emissions in harbor.

Enhanced Ride Through Same as spinning reserve, but on local level in a sub-system like a hotel network or a thruster. UPS

Midway alignment – Ferry operational profile

•  Manouvering, total power demand 3,5MW for 25 min à  Using batteries as spinning reserve and zero

emission operation in combination with variable speed engines during this time will reduce fuel cost and emissions significantly

à  Manouvering take place in sensitive archipelago and rural areas

•  Service speed, total power demand 12,5MW for 2,5h à  Using variable speed main engines in most

optimal SFOC will reduce fuel consumption and emissions signigicantly.

à  In combination with batteries, a high redundancy is gained
