Did you boil a billy for a cuppa this week? Eat dinner by candlelight? Have a cold shower? Blackouts are rare in Australia but this week’s ferocious storms in NSW caused loss of power to thousands of homes, including many of the scientists who work at our energy centre in Newcastle. It prompted us to ask: Will blackouts become a thing of the past as our energy sources change?

The East Coast Low of April 2015 has been devastating. Lives were lost, countless millions of dollars’ worth of damage and destruction to property was sustained, and hundreds of thousands of homes (along with important infrastructure) lost power.

Thankfully, the water is subsiding and emergency services are turning their focus from rescue missions to the clean-up. At the time of writing, electricity companies are still scrambling to restore power to homes and dozens of traffic lights are not operating in Newcastle and the surrounding areas. We’ve heard stories of barbecue-cooked meals and games of Monopoly by candlelight.

Many CSIRO staff, working from our Energy Centre in Newcastle, have been directly impacted by the extreme weather (author included!). The site itself was at one stage closed due to a loss of power and safety concerns; it’s back operating, but in a limited capacity.

Looking out the window at our solar thermal field, and you can’t help but be struck by the realisation that even the best of us still rely heavily on the central electricity grid.

But for how much longer?

The current model

Existing Australian power grids — in particular the National Electricity Market (NEM) grid — have evolved over the last 60 years. These systems were small in number, but had large and remote generators that provided power at high voltage through a transmission system connected to customers through a lower voltage distribution grid.

This system has one-way power flow; distribution networks divide power from large generators into small quantities for customers. But in natural disasters like the one we’ve just experienced, or during times of peak demand (in the summer months, for instance) the centralised nature of the grid can lead to mass power outages.

The future?

One in seven Australian homes now have solar panels on their roofs — one of the highest rates in the world. This ‘community-based’ approach is known as distributed generation, and it’s set to rise.

So, could a grid of the future make widespread power outages (like the one we’re currently experiencing) a thing of the past?

According to Dr Sam Behrens, leader of our Demand Side Energy Technologies research group in Newcastle, it’s a definite possibility.

“With the uptake of new technology, we could see more and more individual houses — or even whole new estates — becoming more self-sufficient during these types of events”

“This would undoubtedly lessen the impact of widespread power outages like the one we’re experiencing in Newcastle and surrounds currently.”

This might align with one of the scenarios from our Future Grid Forum, where around one third of consumers disconnect from the grid by 2050. While this is only one of the possibilities, the ability to store energy is the real game-changer under all scenarios for reducing the impact of blackouts.

Light years ahead – predictions of energy usage in 2050.

“The technology for storing solar power already exists and although it’s a bit expensive right now, companies like Samsung and Bosch are starting to mass produce these batteries, so I think we’re going to see costs come down dramatically in the next three or four years. It could be on a similar scale to the trend with solar panels, where costs came down one hundred fold in the last 10 years,” said Sam Behrens.

“The growing number of electric vehicles on the road now will also make a contribution, as they can be plugged into the house and used to provide back-up power during outages.”

For those who are in the dark as to what our site in Newcastle looks like/does, here’s a taste tester

Hold on to the Monopoly set for now, but future mass grid defection may be closer than you think.

  1. From one Nicholas to another – thanks for spreading the word about the changing solar power industry. Maybe one day soon the United States will adopt solar as quickly as Australia has.

  2. I installed a 4.5kWh Solar Panel array approx 7 months ago and in my first month of receiving 10c/kWh for power returned to the grid I received $28 (off my bill) The bill however was HIGHER than the highest bill we ever received prior to installing Solar Panels.

    A mix-up with my Solar company meant I didn’t receive anything for the initial approx 4000 kWh of electricity I returned to the grid in the first six months. This happened because I wasn’t with an electricity retailer who paid a feed-in tariff. Another thing I did not know when I was `talked-into’ installing the Solar panels was that there is NO `OFF-PEAK’ rate for electricity drawn from the grid at night, so ANY electricity drawn from the grid is charged at the highest rate. This undoubtedly was the reason for my larger than usual bill and I would go `OFF-GRID’ immediately IF I could afford the $20,000 – $48,000 quoted cost involved in doing so 🙁

    All my Solar Panels have done for me is made me $8,000 poorer and allowed me to GIVE a lot of FREE POWER to my electricity retailer who then sold it back to me for top dollar.


  3. Robin: there is no need to research hail-proof glass – we know how to make toughened glass.
    2 years ago, the panels on my roof were unscathed while cars nearby were destroyed. If hail got large enough to break solar panels then I suspect the house would suffer far more costly damage.

    Douglas: The heat returned immediately is slightly less (about 15%) than if the panels were not there. But the remainder eventually appears as heat wherever the electric energy is consumed. So, all told, the difference should be negligible.

    1. Thanks Cameron for the reply, So it would be quite safe to have a child care centre use a flat solar array as a midday open play area, hat but no shade required. Open air offices on flat arrays, just hat and one litre of water from 9am to 4pm. We could replace all sealed roads and car parks that do pump heat into the atmosphere (and cook road workers) with these cooler solar arrays.
