Environment minister and Green party leader John Gormley is in Belfast today.
He is due to address the annual conference of the Greens in the North.
Minister Gormley is expected to focus on the European 'Super Grid' energy concept and what it could mean for Ireland and further afield when he takes to his feet.
The super-grid would aim to draw power from countries with large sources of green energy such as Iceland, which has an abundance of geothermal energy, and North Africa, with vast resources of solar power.
The grid could potentially link Minsk with Madrid, Casablanca with Stockholm, and Cairo with Reykjavik.
The plan has attracted the attention of US President Barack Obama - a point the minister is likely to make during his address today.
