Generus Living Group director Graham Wilkinson said all 350 homes would be pre-wired for solar power so homeowners could have the option of staying on the grid or not.
"It means if they chose that option then they will get 70 per cent refunded back to them when they leave the village . . . It is an incentive."
A communal facility inside the village called the Lake House will operate off the grid with its own solar power and rainwater recycling systems.
There will also be an electric vehicle fast-charge station on site, electric pool cars and composting and recycling hubs.
A market garden, commercial glasshouse, climate-controlled growing house and a variety of fruit trees would also be available inside the village.
