Daily signals at the 298-year-old post ended 18 months ago when Jersey Harbours decided that its £70,000 annual cost was too high.
Since then, flags have only been hoisted on special days such as royal birthdays.
But now a deal has been struck to operate the station more frequently.
The States will now pay the Jersey Heritage Trust £18,000 a year for managing it.
The trust will make sure that the station is ‘dressed overall’ on special days and anniversaries, cones will be flown for strong winds and a flag will be hoisted to mark big spring tides.
The Jersey flag will fly day and night from the mast, which will be floodlit.
The cost of maintaining the station will be met by the States Property Holdings Department.
