LET Byron be the leading light between buildings.
The Byron Shire will see Australia's first Local Electricity Trading (LET) trial when Cavanbah Centre, which has ample roof space and not a lot of consumption, trades energy with the neighbouring West Byron sewage treatment.
LET allows the excess production from the solar array of one building to be credited against the consumption of another building.
Byron Shire mayor Simon Richardson welcomed the kick-off of the trial.
"We are moving one step closer to understanding how LET could work in our Shire," he said.
"The project is a massive game changer.
"Just imagine the Byron Industrial Estate or our CBD's as renewable energy hubs - generating and selling energy to businesses and residents around them."
Data gathered during the trials will be used in a stakeholder and cost benefit analysis report expected by June 2016.
Byron Council Sustainability officer Sandi Middleton said that utilising LET means making the most out of our poles and lines and helping to mitigate the social equity issues arising out of people going off the grid.
