The island is located at the border between the provinces of Västerbotten and Norrbotten but belongs to Skellefteå Municipality.

The island has a weather station, and wind observations from it is reported by the Swedish Meteorological and Hydrological Institute in their shipping forecast.

When it was relocated the current fresnel lens and a gas mantle light was installed.

Nygrån was partly destroyed by ice in 1969-1971 and during this years Pite-Rönnskär was the main lighthouse in the area.

In August 2005 the lighthouse was reactivated as an Occas-light by local summer residents on the island.
