The International Energy Agency (IEA) established in November in 1974 function is to: promote energy safety among its members through physically responding to oil interference and authoritatively providing research and computing on ways to ensure reliable, affordable and clean energy. IEA has a total of 28 members, Australia being one of the members. In Australia, solar energy technologies have become so important (Zhou, 2012). It’s mostly used in remote areas where energy sources such as diesel have become expensive. Nearly one in every home in Australia has a solar PV system on their roof.

Renewable sources of energy such as wind have become affordable sources of power that have changed the nature of electricity generation and distribution (Thackeray et al 2012). Battery banks have been a technology utilized initially in solar power systems that are not connected to the electrical grid (Hill, et al 2012). At night most remote homes need dependable power. For this reason, the best alternative mode of power has proven to be the solar panels since they are cost-effective. However, solar panels can only be used when the sun is shining that is why capturing it in batteries so that it can be drawn for later use is advantageous. An innovation organization tesla has taken a critical move in ensuring that there is zero emission of power generation with the use of these renewable sources of energy.

In Australia, the number of power solar storage solutions is limited but growing. As much as these solar power storage functions slightly in a different way, the principle behind them is the same (Hill, et al 2012). That is solar power is collected in the batteries so that they can be utilized in future. Due to their historically high prices, batteries have been seen as a technology for high-grid power system. Tesla has gone beyond to partnering with renewable power organizations so as to ensure that the grid storage improves resiliency and its cleanliness ( 2015). In addition, the growing popularity of electric vehicles (EVS) has contributed positively to the reduction of prices for lithium-iron (li-ion) batteries. In contrast to the lead-acid batteries, li-ion batteries are long lasting and safer.

Electric- vehicles (EVS) which just happen to be mobile are considered in various ways to be the variation behind the meter storage an improvement by tesla motors. EV batteries could retain a significant amount of energy thus car batteries could provide a backup during an outage (Hill, et al 2012). However, since electric cars draw so much energy during charging, they pose create challenge to grid operators. This is so because they overload the circuits used by other beneficiaries nearby. A way to cut and avoid this has been designed where the EVS are charged at night when the power voltage and the cost are low. By doing this EVs help flatten the load curve of the grid and also draw off power during the night when the demand is low. In addition EVs can produce excess power from wind during the night since they are pulling power off the grid (winters, et al 2012). Vehicle to grid (V2G) technology has enabled a two way operation for the EV battery. For instance when grid operators have excess power they push power to and fro into the EVs battery. The advantage is that owners can be paid for these services. If tesla motors operators could find a way to manage the behind- meter-storage with another technology known as demand response during the day this would be a real game changer. With each passing day it’s quite clear that energy storage investment is here to stay for decades (mckenzie2012).
