Hosted by NSW Farmers and the NSW Department of Planning and Environment, the forum on July 3 will be held at the Mercure Hotel from 6:30pm.

NSW Farmers president James Jackson acknowledged members' concerns over devaluation of property prices, loss of prime agricultural land as well as overall impacts on the economic strength of the region.

"Like any discussion on major developments, it is important to separate the fact from fiction - these forums will provide a key opportunity to narrow down the real issues that must be properly addressed in the planning process when deciding whether or not major solar developments should proceed, and the terms on which projects are developed," he said.

"I dare say if parts of Darlinghurst or Double Bay were being converted into renewable energy zones, those residents would hold similar concerns, and would be loud and forthright in raising those concerns with the government and the media."
