Mr Zawadski said the 300-dish plant would be capable of generating enough clean energy to power the "residential load" of the city.

He said work was expected to commence immediately.

"It will take about nine months for the community to see construction on site," Mr Zawadski.

He said the project would take up to two and a half years to complete.

Mr Zawadski said the company would first go through the approval process and detail planning.

He said the factory-in-the-field would be constructed first.

This is Wizard Power's unique manufacturing and deployment approach for dishes.

In this approach, the bulk of the dish components are manufactured and most assembly tasks are performed.

Mr Zawadski said this approach minimised the installation cost per dish and maximised the rate of at least a dish a day per factory construction line.

He said the manufacturing and construction would produce a "significant" amount of jobs.

Mr Zawadski said material needs would also generate business for local suppliers.

"There are various reasons as to why Whyalla is the ideal location," he said.

Mr Zawadski said it was not only because Whyalla had "great sun" but there was a need for clean energy to support the large local mining industry.

"It is good for business and Whyalla has good grid access," he said.

About 180 hectares has been allocated for the project, however Mr Zawadski said only half of this land would be used.

He said the company had future plans of expansion.

Mr Zawadski said Wizard Power had received "magnificent support" from the Whyalla community.

Currently, Wizard Power has 12 hectares near the Whyalla Industrial Estate and is in the process of building a small scale energy storage power plant.

Mr Zawadski said the plant has only four dishes but demonstrates the ability to store solar energy to meet peak demand, on demand, and will eventually deliver base load power from solar energy.
