A wind farm project on the Nebo-Connors Range, about 175km north-west of Rockhampton, is tipped to create 250-350 jobs at peak construction.
Epuron proposes to start building the Lotus Creek Wind Farm as early as next year, subject to approvals and commercial considerations.
The timeline was included in documents submitted to the Department of Agriculture, Water and the Environment and now subject to public comment.
The project consists of the installation of up to 55 wind turbines for a capacity of up to 450MW, and is expected to have an operational life of 30 years.
The project will supply electricity directly into the national electricity grid. Point of connection will be through a proposed transmission line running through the site and substation in the eastern portion of the site.
Epuron said Lotus Creek Wind Farm would generate around 1,700,000 megawatt hours per annum of renewable electricity per year, equivalent to supplying power to 305,000 homes.
The Environment Protection and Biodiversity Conservation Act referral for the project comes after Epuron announced in December that it had redesigned the wind farm.
Based on additional results from ecological studies and advice from independent ecology consultants, the company said it had reduced the proposed footprint of the project site by more than 40 per cent, from 620ha to 350ha, and reduced the number of proposed turbines by almost a third.
Epuron said the location of each turbine had been individually assessed, to ensure siting in areas of low tree density and as close to existing roads and access tracks as possible to minimise clearing.
