Matthew leads Advisian’s Energy and Water division, assisting clients in both the public and private sectors as they transition to the new energy future. As an industry leader in power engineering and project delivery, he has spent the last 20 years working across the full spectrum of traditional electricity supply and generation in Australia, the UK and the US. He has delivered numerous complex projects including the first integrated control and protection system in the UK, developing power systems for remote mines and delivering capex projects to all the major network companies in Australia. A specialist in the design of energy distribution transmission networks and project managing their delivery, Matt now leads strategic thinking on how government and industry can navigate the new energy disruption towards an economically robust and sustainable future for communities and businesses.

Advisian Asia Pacific Director of Energy and Water, Matt Robinson looks at what Australia’s energy mix will look like as the country transitions from a high emissions industry to one that integrates renewables to a much higher level.

That's the $64 million question isn‘t it? The key point is that we are in the midst of a transition from a centralised, fossil intensive energy system to one that is highly automated, highly distributed and with much, much greater integration of renewable energy, thermal energy and storage technologies. I doubt that we’ll remove all fossil fuels from our energy mix for the foreseeable future but we are going to be able to integrate much higher levels of low emissions energy sources. That’s possible with new storage technologies and also intelligent systems that enable us to control and manage energy in a distributed world. So, I might not be able to predict the mix but I can envision a more varied mix with much less domination from coal and other fossil fuels and a significant growth in distributed storage.

Given that a key facet of this transition is the move to a distributed model, then the technologies that are best suited to that environment will find a place to thrive. We can see an example of that today with rooftop PV. It’s a technology that lends itself to powering a household or business at the premises. You don’t need to be technically minded, there’s virtually no maintenance and modern systems even integrate artificial intelligence to learn how you use the system and optimise it to your usage patterns.

We’ve seen huge cost reductions driven by economic factors more akin to the consumer goods sector and mass-production sharing costs across many thousands of units compared to traditional power plants that gained their economies of scale from producing massive quantities of power and distributing the cost of production across many thousands of consumers. In effect, the technologies that are winning are the ones that reduce the barriers to entry to the energy sector. When a technology gets to the point of PV, where it’s compelling at the mum and dad price point, you’ve really changed something. Battery storage at the domestic consumer level will likely be the next driver of change. Get that technology to become compelling, something near $500 per kW, and you shift everything again because now, the barrier has lowered even more for consumers to self-generate outside daylight hours.

How we get energy consumers to understand the value of reliability or, more correctly, energy security is key to a shift in the energy market. The centralised grid system is a wonder of engineering and operational skill. To be able to almost perfectly match the output of our power plants to the demands of millions of households and businesses across a network stretching over 5000 km from end to end in real time 24/7, 365 days a year is an incredible feat. It’s also massively expensive and complex.

Electricity is an economic and social necessity in today’s world and therefore has incredible value. According to AEMO, the NEM trades almost $10 billion worth of electricity annually and Australia is actually quite a small market in global terms. I doubt that there’s anyone who thinks that they can live without electricity in some way but, like petrol for your car, if you can get it cheaper without a lot of hassle or even just give yourself some certainty about what you pay, many will do that. So, here’s the scary part for the traditional players in the traditional system, up until now, there was no other way to obtain your electricity supply other than through the utility based system. Think back to my previous comments about how the new energy technologies are bringing those barriers to entry down to the point where individual consumers can generate almost all their energy needs on their roof and store it in a box in the garage for about the same price as a luxury overseas holiday.

If you’re still sitting there as the CEO of a network, generator or fossil fuel supply business, and you don’t think this will affect you, think again. I’d turn the question to those businesses directly, How will you articulate your value to your customers in this new, transitioned world?
