Uralla is set to be home to the country's largest hybrid solar and battery facility.
The battery, attached to the New England Solar Farm, will have enough juice to power the entire city of Armidale for about four hours.
Northern Tablelands MP Adam Marshall announcing a $12.5 million State Government grant on Thursday, to support its construction.
The 50 megawatt/hour project will be co-located with the first stage of the 400 megawatt solar farm.
"This is another huge coup for our region and demonstrating the New England Renewable Energy Zone (REZ) is already delivering innovation, infrastructure and industry at a rapid fire rate," Mr Marshall said.
It's the second major battery project announced in the last two weeks, with the Sapphire Battery Farm, slated to be built outside Glen Innes.
"It's astounding to think in just two months since the REZ was announced, our electorate has seen $22 million invested by the state government in flagship renewable energy projects, helping to create 84 construction and operational jobs," Mr Marshall said.
UP/AC Head of Solar Development Killian Wentrup said the project could be expanded if the cost of batteries continues its trend downwards.
He estimated the project would create as many as 200 jobs at peak construction.
"Solar energy combined with battery storage is a clean, reliable, cost effective way of supplying NSW homes with their energy needs into the future," he said.
