Big utilities charge into distributed energy, one step at a time

This will not be a “Big Bang” event like that of their European and north American peers, E.ON, and NRG. But Origin Energy and AGL Energy, the largest electricity utilities in Australia, have seen the future, and decided it is in distributed energy. And they are determined to embrace it, albeit in their own good time.

AGL Energy this week became the first of the big energy retailers in Australia to publicly launch its new zero-down rooftop solar product, a power purchase agreement that will see AGL own the panels, and customers pay for the output.

AGL Energy was the first only because Origin has chosen to fly under the radar. In the past few months, it has been trialling a similar product with family and friends, and last week quietly opened it up to the public.

Both utilities are taking a softly, softly approach. AGL says its Solar Smart Plan of will be “limited volume” in NSW and South Australia. Origin is also starting slowly. The reason appears to be this: distributed energy works against the very model that has dominated their industry for a century. Getting the balance right will be critical for the future of both companies, and many others.

Marc England, who heads the New Energy and strategy division at AGL, which will encompass rooftop solar, battery storage, electric vehicles, and home energy management systems, says this is a different type of service.

“It is different to just being a centralised grid provider,” England tells RenewEconomy in an interview.

So have the big utilites come late to the market? “Everyone would say we are late into the market. We’ve made no claims otherwise, but we are getting serious about it now. It’s important we do it right,” England says

And how quickly will this transition occur? “It is a gradual change. It is dramatic in many respects. It will evolve in the next 5, 10, 15 years.”

And so, what wins out in the end, decentralised or distributed generation? “We think the future is both,” England says.  “It will not be one or the other. But there is a definite shift towards more distributed form of generation and management of energy at home.”

It is the scale and speed of this transition that is the subject of great debate. E.ON thinks it is happening so quickly it is E.ON_renewables_200_150_s_c1ready to jettison its centralised, fossil fuel assets. NRG in the US also thinks it is happening quickly. So do the myriad small players, and not so small solar giants like SunEdison, SunPower and even Google that are entering this market.

AGL Energy is betting it is progressive, and that the vast majority of customers remain “fully on the grid”. As we reported last November, when England made his first big presentation, AGL Energy expects one-third of customers to go either off the grid, or through battery storage, partly off the grid, by 2030.

But the remainder will stay, England believes, due to a combination of demographic, housing and technology factors.

“While some people will want to go off grid for various reasons, that will not be right answer for everyone,” England says. “Having back up from grid, to be able to export to the grid, to share energy in the future, in different models, that will be important.”

Still, even if England recognises that the big utilities have been late to solar, and are now targeting the “family market” that hasn’t been able to afford the upfront payments, he wants to ensure that AGL is at the front end of the storage revolution, as we report here in our story about AGL offering battery storage to customers before the end of the year.

“We are going to continue to innovate our business model, to learn as we go to try new things. We need to learn to create value for shareholders in a slightly different way. The PPA product is one step along that journey.”

Over at Origin Energy, the company is also recognising that distributed generation is the future. CEO Grant King said last week there could be 20GW of rooftop solar in the country by 2030, a number that would turn the current dynamics of the energy industry upside down. And storage, electric vehicles and smart management systems will also follow.

But is there a role for gentailers like Origin and AGL in such a future? If the likes of Ron Stobbe, the head of SA Power Networks, the monopoly network operator in South Australia, are right, then a future of decentralised generation will leave room for networks, but not much room for centralised generators and retailers.

That’s because centralised generation will be gradually phased out as up to 50 per cent of power is sourced locally. And the retailers will need to find Something To Do, apart from just packaging up bills. Hence the push into the ownership of solar and storage, and maybe even electric vehicles down the track. Although not everyone thinks that PPAs are good for consumers.

Origin might be better placed among the gentailers because it is less exposed on the generation side, reasoning it is a better bet to buy some of its electricity on the wholesale market, where prices have been at record lows, than it is to own the assets. That means it has less of a generation portfolio to protect against the incursions of decentralised energy. It now seems to be a deliberate strategy by King.

Last week, RenewEconomy interviewed Frank Calabria, the head of Origin’s energy markets division, and Phil Mackey, who has been brought in to head the newly established New Energy division, and lead the solar strategy.

“We are rebuilding the solar business, renewing the focus around it and looking at the business models of the future,” Calabria says.

One of these is pay as you go method implicit in the PPA strategy. Origin has a partial payment system as well.

Adds Mackey: “We’re interested in solar as a distributed energy source, whether in residential or commercial space. We prefer the model where we own the systems and sell the electricity. That’s because it is closer to our current existence as an energy retailer, and it avoids a race to the bottom on price and quality.”

The question for both companies is can they keep pace? And can they rely on their “brand” power retaining consumers when greater choice is available?

Right now, they are taking it slowly. “We are just assuring ourselves of our ability to sell the product,” Mackey says. “We are reluctant to dive into the market until we are sure that customers will be delighted by the product.”

But they don’t have that much time. “It is going to evolve,” Calabria says. “It will be a relatively fast evolution.” Particularly when it comes down to storage, and the options that that creates for consumers.

“It is a fast moving space. We are watching it closely. It (the storage market) is clearly moving rapidly globally. It is early days , and we are looking at it as part of the mix. How that works out is too early to say, but it could be that it could occur faster than you think.”

    The future of off-grid, micro-grids and grid distribution will probably come down to the prevalence and battery capacity of EVs. If most households have EVs, then there would be no reason that they couldn’t go off-grid with only about 1.5 days of stationary battery storage. On days of low solar generation, they would use their EVs to recharge their house batteries or use the power directly from the EV battery.
    During winter, when solar generation is consistently low, they would mostly charge their EVs at grid-connected fast-charging stations, similar to how people currently use service stations. This would allow them to import energy from the grid without having to be connected. For the other 9 months of the year, they would probably be able to charge their EVs at home most of the time.

    In this scenario, grid power would be distributed to areas where it is difficult to have high PV penetration, such as CBDs, high-density urban areas that have many large apartment blocks, and heavy industries and public services like hospitals that have large energy requirements that cannot be met solely by PV. The grid would also be used to supply (or provide back-up supply) to a large network of EV charging stations.

    Most of the grid energy would probably still come from large generating facilities that might be very distant from the sources of demand. So there would still be generators and the long-distance transmission grids that we currently have.

    What would change is the prevalence of the suburban, 240V distribution system. I don’t really see the point in micro-grids if battery storage becomes prevalent. If you are relying on rooftop PV to provide energy for the micro-grid, there is no advantage in distributing excess energy to your neighbours if you can instead store it at home. If everyone has PV, your neighbours won’t need your excess energy. And I doubt if it would be any more cost effective to store the energy at a suburban battery depot than it would be to store it at home. So, if EVs and battery storage become prevalent, there doesn’t seem to be any point in providing or maintaining the 240V suburban grid.

      on your last paragraph, what about the scenario where you have two houses, each with solar and same capacity battery, micro-grid connected.

      The storage economics mean you need to run the batteries as much as possible to keep the LRMC round discharge cost down.

      Having a lot of standby storage capacity there for the rare times jacks the price up.

      If the two houses can trade stored electricity they get the benefit of more storage but at a lower price.

      So stepping back, I’d counter that the volatility of energy need on an individual basis is actually more dependable on an aggregate basis so a micro-grid can target that (or even regulate dependability through smart appliances or demand side mgt).

      Therefore, the micro-grid becomes justified.

        EVs would provide the back-up storage at no extra cost. There would be no need to have more than about 1.5 days of stationary storage.

        The SA network company who was advocating microgrids was proposing a flat annual charge of $750 to be part of the microgrid. Why pay that sort of money to occasionally exchange small amounts of energy with a neighbour?

          I don’t know about that price.

          I guess I just think economically, we’re better sharing infrastructure that isn’t 100% utilised. I’d saywe’re just in a funny spot because the pricing for the networks is so buggered right now.

          That’ll need to be rectified as I believe mass grid defection will not be the most efficient for us as a society.

      For your scenario to come through you will need to count on the EV manufacturers and most of them currently don’t support the idea of EV batteries being capable to be used as back-up batteries.

      I think the scenario described by WR is entirely feasible. Indeed it appears the big utilities such as AGL and Origin have realised this too and are positioning themselves to service the residential solar/battery storage market.

      I imagine the product they will be wanting to sell will be a residential off-grid solar-storage system retailing at approx $10-12k, thereby locking customers in for a 5-7 year contract paying around $2,500 p.a.

    How absolutely laughable. Opportunists who suddenly realise that their customers have moved beyond them already and expecting us to forgive them for corruptly distorting the system for so long. Including funding the eliminating of a scheme designed to transform the economy to low carbon. Screw them.

      They’re sort of waving a white flag, but refuse to come out of the trench.

    So, these big retailers have finally figured that distributed generation is the future, and that the role of a network is to collect and store surplus energy for distribution at times of high demand? My goodness, but they’re slow: they should have subscribed to Renew Economy years ago.

    Had they done that, they’d have a few clues by now.

    If our wish is to move to decarbonised electricity as soon as possible, this is good news.

    I don’t see how distributed energy and big utility can possibly be compatible. I don’t see a future for those companies, so their best option if distributed energy becomes mainstream is specializing in heavy industries and other companies that will require a grid.
