Battery capacity depends on user needs

 

There are many things to take into account when looking at an energy storage battery for your home or business. These include what you want your energy storage battery to do as well as its safety, performance, operating temperature and end of life recyclability.

Unfortunately many people only look at the initial purchase cost of batteries and this is what they use to compare different batteries. This doesn’t take into account what a battery may cost them over its lifetime or the cost to the environment of both the battery’s manufacture and end of life disposal. To make a realistic comparison of a battery’s cost you need to consider it’s full “cradle to grave” impact on all areas, including its safety during operation and it’s environmental impact.

Problems solved with battery storage

One of the biggest problems with the efforts to use renewable energy to produce large amounts of the energy consumed on a daily basis has been its inability to reliably supply power at the times it is most needed. This can and will be addressed with the installation of battery systems that allow households, businesses and energy network providers to store renewable energy for use at night or in peak periods.

Solar panels convert the sun’s rays into electricity during the day with maximum generation being between the hours of 11 to 3pm. Unfortunately, for most people unless you are home during the day 80% of this power gets fed back into the grid for very little return. Likewise, although energy generation through wind is now very efficient and cost effective the times when wind produces energy can be intermittent.

Batteries also reduce the amount of electricity that is exported to the grid from rooftop solar during the middle of the day. This has the capacity to significantly reduce variability and stabilise grid supply. Continue reading “Problems solved with battery storage”

Why will I choose energy storage batteries?

 

There are a variety of reasons that people choose to make use of battery storage. In the domestic market the most common ones are to reduce the price they are paying for ever increasing electricity costs by shifting power from their solar panels collected during the day to when it is needed at night.

There are many other people for whom the desire to be energy independent is the driving force, even if they still stay connected to the grid. This may be because of dissatisfaction with treatment from power companies or due to an unreliable supply. Continue reading “Why will I choose energy storage batteries?”

Focus on the Solution – Not the Problem

 

Powering the new economy with clean energy

 

Many households and businesses already attach battery storage to their clean energy systems. Now is the time to grow the industry, encourage the take-up of storage and help make Australia a renewable energy leader. With public interest high, now is the time for a targeted, five-year support package to drive down costs and put battery storage in reach of every household and business.

Battery storage can reduce network peaks and troughs by storing electricity during off-peak times and discharging it during the peak. Continue reading “Focus on the Solution – Not the Problem”

Battery power rating

Before purchasing any battery storage it is critical that you understand what you want to do with the battery. If you only want to shift some energy generated from your solar panels during the day to be used at night and don’t mind if you don’t have power when the grid goes down it isn’t as critical that your battery needs to be able to provide all the power you need.

However, if you want to be energy independent and want to have power in times of power outages (as most people do that purchase batteries) then you need a battery that is capable of running your house for a period of time. You need to consider your appliances and what you consider essential and determine what power will be drawn down by all of them. As can be seen in the above image you may need multiples of some battery technologies to accomplish this which may greatly increase the cost of an installation.

Peak shaving to reduce peak demand charges

For many businesses it is important to look at using battery storage to reduce peak demand charges.  Often, even one large energy spike can greatly increase total energy bills with this drawdown increasing the energy charge for all power usage. If the peak demand needed can be reduced then the overall electricity charges can be reduced.

Peak demand usually occurs when several high energy using pieces of machinery come into use at the same time, particularly if this machinery has large initial starting energy draws.

Peak demand is usually calculated based on the highest 15 minute average usage over a given month, even if it only occurs once a month (some energy retailers actually use the maximum usage over a yearly period, again even if this maximum only occurs once a year).  These demand charges are also often charged on a tiered scale with higher charges the higher the peak is.

Why is energy storage pushed as needing an ROI

Why is energy storage pushed as needing an ROI but water tanks are sold to help the environment.

It is interesting that many people looking at battery storage look on it as an investment with a ROI when this philosophy isn’t used for any other household appliances. Nobody ever asks what is the ROI of a fridge or a car.

When water shortages are an issue, people are encouraged to purchase water tanks to supplement water storage supplies, however there is never mention of ROI for these, possibly because if water tanks were purchased to reduce the cost of water rather than to protect the environment they would never pay for themselves.

GridEdge and the FZSoNick battery

GridEdge is a company that delivers both off grid and on grid energy supply to all levels of consumer demand. 

GridEdge has the Australian and New Zealand distributor rights to the FZSoNick sodium nickel chloride battery which has superior operating capabilities, compared to any other battery technology, currently available. The SoNick battery operates at a wider range of temperatures compared to other batteries and has the advantage of being a non-toxic, environmentally friendly battery that is much more compact, compared to many other batteries set up currently on the market or proposed in the near future.
