We have had a lot of interest lately in a report MEFL did for the Australian Renewable Energy Agency (ARENA) on microgrids. A microgrid is a small local network that allows its members to share electricity generation and storage. The report is titled Here Comes the Sun.
In past issues we have looked at various battery storage technologies. Recently we have received some questions about the broader topic of battery storage as it affects householders. In this article, we explore the concept of battery storage and the key considerations householders and businesses need to make when deciding on its suitability and type.
Currently, many Australian households pay 20-30 cents per kWh (note: kWh is a unit of energy) of electricity, and receive 5-7 cents per kWh, both depending on their retailer. Some early adopters of solar systems may still be receiving the ‘premium’ 60 cents per kWh Feed in Tariff rate for excess renewable energy exported to the grid.
The energy storage market is an exciting place to be right now, as anyone with an eye on the industry will attest. In this, the second in the series on emerging battery technologies, we take a look at the Redflow Z-Cell. This is a new home-grown entrant in the domestic energy storage market, competing with the likes of Tesla and Enphase.
