Origin Energy says storage will trigger new wave of solar installations

Origin expects battery storage to spark a new wave of rooftop solar installations, but not until the costs of storage falls. And that could be a while.


Origin Energy predicts that battery storage will trigger a new wave of rooftop solar PV installation in Australia, although it is not likely to happen until the cost of battery storage falls to interesting levels for consumers. And that could take a while.

In a presentation made during its “analysts day” in Brisbane, by CEO Grant King and line executives, Origin Energy said it believed it was well placed to manage the big changes happening in the energy market now, saying it was position to take advantage of solar and storage, the changing energy mix as coal retired and more renewables were installed, and in managing its renewable energy obligations.

On the issue of solar, Origin Energy expected the rooftop market to be subdued, with continued falls in the domestic market to be offset by an increase in the commercial market, as more businesses turned to solar to offset grid costs.

But Origin said battery storage could trigger a new wave of solar investment, from about 2020 – echoing general comments in the solar market in recent months about the likely link between solar and storage in new installations.

However, Origin Energy – while making solar and storage offerings to consumers and moving into the energy services business – is not expecting battery storage to deliver short paybacks any time soon.

It says it will be a while before there is mass market appeal, and paybacks of less than 10 years may not be realised for the average customer until nearly 2030.

Some in the industry agree, others do not, suggesting that the interest in battery storage will not be decided only by pay-back times, and/or that costs will fall quicker than expected.

That’s not everyone’s take. Indeed, Bloomberg New Energy Finance suggests costs are comparable now in certain situations and particularly with smaller storage systems.

Origin, though, is in the Gates camp on costs, and reproduced this graph below suggesting that using storage to go off-grid, or even nearly off grid, are prohibitive. There is plenty of debate about those estimates.  origin cost off grid

As for its overall business prospects, Origin Energy expects to do fine in the LNG business, despite predictions from the International Energy Agency that the global market will be flooded post 2020.

Recent jumps in the wholesale price appear to support that theory.

Origin also expected, unsurprisingly, that there will be no new coal fired generators in the country. Indeed, it suggested that coal retirements could be greater than expected, and renewable energy installations also higher, depending on the outcome of elections and policy.

    Origin’s Figure 17 is absurd. It seems like they have no idea that aggressive competitors could show up with batteries well under $150 per kWh by 2018.
    Their reasoning appears to reflect their desires not to have their business model disturbed, rather than any understanding of the pace of change in the world today.

      Their argument is based on an attempt to take control away from the customer. So too AGL.
      The payback graphs are based on vanishing concepts.

      Indeed. The prices they’re assuming are *already* obsolete given the known production costs for Tesla battery packs.

    A member of my family installed a 1.5kw system with Origin back in 2010. She now would like to increase the system size, doubling it. Her inverter can take 3kw. Origin has told her that because the original Sharp panels are no longer made this can’t be done and has fobbed her off. Seems to me that there is an opportunity for upgrading systems that is begging to be taken up by clever companies.

    Bloody clowns… don’t care if they get it wrong… however, battery price will not necessarily decline significantly as greater demand also raises the price.
