Home Batteries in Australia: The Market, Applications, and Results

by Adam Champion on March 2, 2017 at 5:30 PM

Australia is quickly becoming one of the leading markets for residential energy storage.

There are a few key reasons for why this enthusiastic uptake of home batteries is happening:

  • Australians already love solar power. Government incentives over the last 10 years have helped enable the installations of more than one million residential solar roofs. So, solar PV technology is in just about every neighborhood.
  • Australians use a lot of energy with a significant portion driven by air conditioning loads.
  • Some generous solar feed-in tariffs (rates of up to 60 cents/kWh for all energy created) have now come to an end. This means that for many households excess solar generation is now earning them very little.

New Solar Battery Safety Policies for Australian Homeowners

by Aquion Team Member on February 17, 2017 at 12:17 PM

The possibility of new regulations restricting lithium-ion battery installation in Australian homes could have a major impact on the energy storage industry.

Safety concerns surrounding lithium-ion batteries have inspired a variety of policy initiatives restricting their usage in homes or densely populated cities.  For instance, in November, New York City’s fire department and the New York State Energy Research and Development Authority (NYSERDA) convened to address the very real concern about lithium-ion-related fires in New York City and commissioned a study on how to handle potentially flammable storage systems in an already complex and outdated New York City grid.  Perhaps piggybacking off that initiative, the issue has once again become a hot topic - this time in Australia as officials with Standards Australia are proposing tough new rules for the installation of lithium ion batteries in homes.

Integrated Energy Storage System Installation in Rural Australia

by Claire Juozitis on January 9, 2017 at 10:21 AM

Plug-and-play systems are making it easier and easier for homeowners to install energy storage. 

Titan Energy Storage, a subsidiary company of our partner, Fusion Power Systems, developed one of these integrated solutions specially with Aquion batteries for homes in Australia.  We recently heard from an installer in Australia about some homeowners who installed Fusion’s Titan SmartStorage for self-consumption and reliable backup power in case of grid power outages.

Why Storage? Part 4: Demand Charge Reduction

by Chris Rigatti on December 15, 2016 at 3:17 PM

For our last post in this series, we'll look at peak demand charge management.  

While demand charges have been used for commercial and industrial customers for some time, they’re relatively new to residential customers.

Most residential energy bills in the US today include a fixed charge to cover the cost of maintaining the grid infrastructure, which is the same for every customer, and a variable charge based on the amount of energy (kilowatt hours, or kWh) used in a month which covers the cost of generating that energy at a power plant.   With peak demand charges, the fixed charge is replaced by a variable charge based on the maximum power (in kilowatts, or kW) that a customer uses in the month at any time. While this might seem like a penalty, it tends to be a good thing for the electricity system as a whole, because utilities need to invest in infrastructure to handle that peak power demand, even if it only occurs for a few minutes each month.  Peak demand charges are a way of passing the costs along to the customers that actually incur them.

Why Storage? Part 3: Time of Use Optimization

by Matt Maroon on November 29, 2016 at 12:26 PM

Energy storage can do a number of jobs when connected to a solar-enabled residence. 

We’ve already outlined some of the benefits of energy storage when it comes to maximizing solar usage— self-consumption, backup power during  outages, and islanding (increased autonomy).  Another useful application is time of use optimization. For the homeowner, this means using energy from your batteries when variable rates for grid power are high due to increased demand based on time of day/year. Batteries can be charged from the grid overnight when power is cheapest and then, for example, used to power your AC at the hottest (and most expensive) time of day. But, time of use optimization has other major advantages. Did you know that energy storage, even when installed at private residences, can contribute to solving larger grid and environmental issues?
