Utility Scale Storage

Inaugural global energy storage report by GTM Research finds that Australia’s behind-the-meter storage market tripled in 2017, while the U.S. remains the world’s leading market with an installed energy capacity of 431 MWh. China poised to rise to second place globally in 2019.

After the 50 MW Stage 1 solar farm was switched on late last year, the Kidston renewable energy hub has now received a development approval for 270 MW of solar, which is to be co-located with a 250 MW pumped storage hydro project.

Fluence says that Australian governments, regulators and grid operators are ‘learning-by-doing’ in their application of large-scale battery storage. The technology provider on the new 30 MW/30 MWh utility-scale battery at Ballarat indicates that the approach could deliver significant savings when compared with grid upgrades that could be considered “not optimal” as battery technology rapidly improves.

After the Australian Renewable Energy Agency (ARENA) provided an extra $25 million to match the Victorian government’s funding offer, the state of Victoria is now in line for two large-scale, grid-connected batteries, one of which will be coupled with an existing solar farm.

Annual solar installations grew almost 20% year over year in 2017, and the solar industry is also edging within 100 gigawatts, a milestone the industry will reach this year, according to IHS Markit, a world leader in critical information, analytics and solutions.

Panel discussion at Energy Storage Europe tackled the issue of whether the best way for keeping the lights on as economies around the world grow is to extend the grid network or add energy storage, and found that the best solution lies somewhere in between.

French firm Neoen has begun development on a hydrogen electrolyser to be colocated alongside a 150 MW wind project and 150 MW solar farm. The project has been awarded a grant of $1 million by the South Australian Renewable Technology fund, with more funding yet to be approved.

Despite a lackluster Q4, GTM Research predicts that the U.S. energy storage market is going to boom in 2018, driven by both policy support and falling prices.

Australia’s first large scale solar+storage array has been grid connected, in Northern Queensland. The collocated 10.8 MW solar and 1.4 MW/5.3 MWh battery storage system is set to demonstrate the value of dispatchable PV to networks and asset owners.

Despite hitting a record 1.17 GW of new grid-scale storage capacity in 2017, growth was a mere 4.6% on 2016 having surged 61% the year prior. Industry’s reliance on policy support means foundations for growth remain uneven, report finds. Average costs, however, fell by 24% last year.
