Home energy management systems

Now that solar feed-in Tariff (grid rebate) rates are so low across Australia, there’s little reason for any solar system owner to send their energy back into the grid, as such they will always save more money by 'self-consuming' their own generated energy.  This is the main reasons the popularity of battery storage systems has grown so rapidly, batteries provide an unprecedented degree of energy self-sufficiency for households and businesses across Australia.

Understand: If you already have Solar, then becoming totally independent of the state grid will be a LOT cheaper, as you only need to purchase a battery bank with a capacity close or greater to your Overnight energy consumption (the larger the better).

We recommend you maintain you grid connection as back-up, even with a $0.06kWh Rebate, as if you are harvesting excess energy, that should cover your "retailer supply charge", or alternatively install a small 3.5kW silenced automatic start generator to totally secure reliable power production 24/7.

We have the vision to see the future lies in P2P (Peer to Peer) energy generation !

Bespoke Energy Retailers (are Not really Retailers)

However having a solar & battery system that harvests & stores at least 24 hour of energy, means you have eliminated your energy bill and from that day onwards you now have the option to choose who you export/sell your excess energy to!

There are greater benefits offered by joining one of several forward thinking Bespoke Electricity Retailers, but this may be reliant on your battery type being suitable to there software, these companies offer 'Grid-Credits' of up to $1.00 for every kWh of energy they harvest from your battery system, usually at peak times, driven by consumer demand.

The new breed of 'retailers' mentioned below, use a Reposit Box that costs between $500~$1000, and includes advanced software that logs your energy production & usage, Reposit software is the same type of software the state grid use.  A Reposit Box independently monitors your energy production and usage, But Reposit does not work with all battery types, they currently require a battery system to use battery maintenance system (BMS) to see what condition your batteries are in.  Unfortunately for Reposit, the Reposit-Box has not yet been tested with one of the oldest and most proven and reliable batteries, being Nickel Iron (NiFe) batteries, this is largely due to the fact the newer types of batteries like Lithium etc. are more susceptible to heat damage, and require a cell temperature circuit as Lithium batteries can be damaged due to over charging & over discharging, where NiFe batteries themselves are virtually bullet proof from Overcharging and Depth of Discharge (DOD), largely due to the fact the energy is stored in the Electrolyte, and not in complicated and heat sensitive material matrix of lithium & other battery technology!

So, if you choose to use a Reposit-Box, they can/will harvest some or equal to all of your normal un-used/excess stored energy, this is done as mentioned, by automatically harvesting the energy from your batteries at a premium on the spot market price, giving you up to a $1.00kWh Grid Credit, this Harvesting can happen 24/7, usually only when the state grid in your area requests more energy, obviously this is better than 6 cents per kW feed-in Tariff that most retailers offer.

Spot market price spikes have certainly increased in the last few years, whether or not this will remain a permanent feature of the wholesale market is unknown, in Australia with the abundance and affordability of Solar, also open the way for the possibility of Pumped Hydro, meaning during the day water is pumped back upstream (higher elevation) to a Dam, Lake etc. then the water is released and used in Peak demand times, like in the evening, But whilst we have dumb self serving politicians in office we may never see this happening unless privately funded, however the future looks bright in this area due to the current cost of Solar.

The Higher number of energy spikes mean bigger savings for Peak Time selective energy harvesting!

Peak Time feed-in Rebate (PTR) question:

How much will a selective harvesting program actually earn you?

The answer is impossible to know, given the range variables that come into play, however an educated guesses would be from $0.40~$1.50kWh.  We assumed that a system owner will earn 40c/kWh every time the spot market price goes over 50c/kWh, or 90c/kWh every time it goes over $1.00/kWh (i.e. the Retailer keeps 10% commission, as they don't actually supply or pay for the power you receive).

We looked at three export volume scenarios: Whether the home/business exports 0.5kWh, 1kWh or 3kWh at each price spike.

Over the first three months of 2017, the amount of credit that someone could earn from selective harvest could range between as little as $3 to as much as nearly $350 – depending on the state, the rate paid and amount of energy harvested/sent back to the grid. At the moment, Queensland appears to be the best place for selective harvest programs.

Also keep in mind the fact that opportunities to benefit from selective harvesting are likely to increase as the grid becomes more distributed and interactive, as more home energy systems get equipped with ‘gateway’ technologies, as in-home energy management systems that enable selective harvesting are likely to grow.

And don’t forget that the main way that solar & battery system owners will save money is to use their energy themselves. In our opinion, selective harvesting programs will always be a bonus on top of the savings made through self-consumption.

These are some Bespoke Electricity Retailers offering $1.00 Grid-Credits;

  • (1) QLD/NSW/VIC/SA: Diamond Energy Victorian based company.
  • (2) QLD/NSW/VIC: Power Shop is Canberra based company.
  • (3) ACT: Simply Energy Canberra based company.
  • (4) Red Energy is 100% owned by Snowy Hydro, NSW.
  • (5) Origin Energy offer 12c kWh Rebate if you purchase their over-priced Solar System.

Some of the above businesses - somewhat compete with what we are offering. However, we strongly believe that all customers should have the final decision on who they purchase there equipment from!

We are not focused on large profits like many business, we hope you will consider what we are offering, the bottom line is you will always need to get a qualified electrician to grid connect a Small Generation Unit (SGU) you purchase, we only offer you a go-to gateway to true independent Wholesale prices, allowing you to build your own affordable Micro Power Grid.

(1) Diamond Energy are the first company to offer a Grid Credits plan. With Diamond’s Grid Credits 100 tariff, you get an impressive $1.00 per kWh for each Grid Credits event. Diamond Energy is passionate about renewable's, clean generators such as wind, biomass and solar. Diamond believes customers can be a part of the renewable energy solution and Grid Credits is the next step.

(2) Power Shop is a Canberra based start-up – to find new and more intelligent ways for consumers to get the most out of their solar and batteries, to save money and the environment.

(3) Simply Energy is a Canberra based company.

(4) Red Energy only offer a small feed-in Tariff.

(5) Origin Energy offer a 12c kWh feed-in Tariff, only if you purchase there equipment & based on there market rates "without discount", so the 3c kWh additional feed-in Tariff they offer is not a genuine offer as the profit they make on there system outweighs there offer before you start.
