RayGen is investing in scaling its business to deliver utility-scale renewable power plants across several sites in Australia.
Need
RayGen has developed a new approach to solar generation and long-duration energy storage. Today, the National Electricity Market energy grid is comprised of ~25% variable renewable energy generation through solar and wind. These generation sources are an important step for the country’s decarbonisation plan, but there are limits to the amount of variable and inverter-based generation the electricity grid can accommodate before issues start to arise. Variable generation from solar has resulted in large swings in the value of daytime electricity, which is now routinely valued at below zero during periods of high supply and low demand. Furthermore, inverter-based generation from solar and wind sources do not have the same ability to overcome voltage fluctuations in the way synchronous generators (e.g., coal-fired power stations or gas turbines) do, through natural inertia. Low system strength can lead to grid instability and, in some cases, total power failure. |
