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

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
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
