A solar farm in Australia finishes its panels, not yet a working plant
European Energy Australia has finished installing all 200,172 solar panels at its Winton North project, a solar farm and battery site about 22 kilometers southwest of Wangaratta in Victoria, Australia, between the towns of Glenrowan and Benalla. Finishing the panels is a construction milestone, the point where all the physical equipment that turns sunlight into electricity is now in place. It is not the same as the plant switching on and selling power, which the company expects in 2027. The solar side of the project can generate 131 megawatts, the unit that measures how much power a plant can produce at any one moment, measured before conversion and called direct current. Once converted to the alternating current type of power that actually flows through the grid, the same panels can only put out 100 megawatts. The site covers 256 hectares.
The panels can generate more power, measured before conversion, than either the grid connection or the battery are rated to carry.

How the panels reach the grid in Australia
The project connects to the transmission network run by AusNet, the company that operates high voltage power lines in this part of Victoria, at the Glenrowan Terminal Station, through about 5 kilometers of cable that runs partly overhead and partly underground. All Energy Contracting, a construction company based in Melbourne, won the contract for the electrical and trenching work in late 2025. Its scope covers 23,399 meters of trenching, the ditches dug to bury cable, plus 86,312 meters of medium voltage cable and 206,390 meters of direct current cable, the wiring that carries power away from the panels before it reaches the grid. All Energy Contracting also states the finished project will offset 170,000 tonnes a year of carbon dioxide equivalent, a way to measure the combined warming effect of different greenhouse gases on one common scale, and could power 40,000 buildings a year, figures only the contractor has published.
Figures are the scope All Energy Contracting states for its own work on the project, not a total for every contractor involved.

The battery that makes the power useful after dark
European Energy is also building a 100 megawatt battery on the same site. The company own project page describes it only as a battery that runs at 100 megawatts for 2 hours, which multiplies to 200 megawatt hours, a figure this article calculated from those 2 numbers rather than one the company states outright. Once both the panels and the battery are running in 2027, the combined project is expected to generate 227 gigawatt hours of electricity a year, a measure of total energy produced over time rather than power at any one moment, sold under contract to Amazon for its data centers.
Co locating battery storage with solar generation means clean energy can be stored and dispatched when the grid needs it most, helping strengthen reliability as Australia transitions to renewables.

The real financing, and a mix up worth avoiding
Winton North itself reached financial close, the point where lenders commit the money a project needs before construction can be paid for, on July 2, 2026. The lenders are Commerzbank and Societe Generale, named in the press release European Energy published announcing that close. Coverage of the panel completion also mentions a separate AU 130 million dollar financing package from Westpac Banking Corporation and DZ Bank, closed in June 2025, but that money financed 2 other European Energy Australia projects, Lancaster and Mulwala, not Winton North. Reading the financial close release directly, rather than only the news coverage that mentions the older financing in passing, is what shows the difference. Amazon Web Services, the Amazon division buying the power, holds a power purchase agreement, a contract to buy the electricity a plant produces, for the solar output, and signed a separate agreement for what the battery produces.
We continue to build a diversified portfolio of renewable energy projects here in Australia that combines strong resource fundamentals with increasing demand for flexible generation and long term power offtake.
