Chinese power technology giant Sungrow has unveiled a series of new storage and micro-grid technologies that it says will enable batteries and renewables to broaden their scope amid the rapid changes in energy markets and grid demand – and to scale up the speed of deployment.
The falling costs of battery storage and rising efficiencies means that battery providers can deliver double the storage in the same space, and at the same price, as what they were able to achieve just a few years ago.
AGL, for instance, has been able to build a new 2,000 MWh battery at Tomago, twice the size of its first big battery at Liddell, at around the same cost. And the costs are still falling and the efficiencies continue to improve.
At the recently held Global Renewable Energy Summit in Hefei, Sungrow unveiled the latest in its grid scale battery solutions, dubbed PowerTitan 3.0, which it says integrates more than 600 stacked battery cells, a round trip efficiency of up to 92 per cent, and grid-forming capabilities – crucial in a high renewable grid.
Sungrow says the AC block design supports factory pre-installation and pre-commissioning, which means that the system allows for “self-configuration and self-check within one hour” – enabling a 1 gigawatt hour project to be deployed in just 12 days.
