Grid-scale battery storage has emerged as the popular possibility to make sure dependable electrical energy provides in areas of New South Wales, Australia, transmission operator Transgrid has stated.

Transgrid has checked out “a number of choices” for addressing load constraints on the community in and across the cities of Bathhurst, Parkes and Orange in addition to the North West Slopes areas of New South Wales (NSW).

Every space is experiencing progress in electrical energy demand and the development is anticipated to proceed. Constraints might result in failures in delivering dependable provides of electrical energy.

Transgrid is supervisor and operator of the excessive voltage electrical energy community serving New South Wales and the Australian Capital Territory (ACT).

The grid operator issued Undertaking Evaluation Conclusions Reviews final week, regarding potential funding choices that it will search approval for from the Australian Energy Regulator, with Bathhurst, Orange and Parkes areas thought of in a single report and the North West Slopes in one other.

“We checked out a number of choices for addressing load constraints on our community and we’re excited to say that grid-scale batteries have been recognized as the popular possibility as they supplied the best general profit,” Transgrid govt common supervisor of community, Marie Jordan stated.

It is among the first occasions up to now large-scale batteries for the Nationwide Electrical energy Market (NEM) “have outperformed different choices all through the regulatory take a look at,” Jordan stated.

Battery tasks proposed by two third-party suppliers ranked equally as the highest possibility within the Undertaking Evaluation Conclusions Reviews.

They’d have the ability to take part out there along with assembly their community help commitments, however this participation can be restricted throughout winter and summer season intervals when community help wants are more likely to be extra acute. In spring and autumn, market participation can be much less restricted.

Batteries would have the ability to cost with renewable energy at occasions of plentiful technology and off-peak demand intervals, discharging to the community when technology is decrease and demand greater. They’d additionally present providers like reactive energy help.

For Bathhurst, Orange and Parkes, the buildout would comprise a 20MW/40MWh battery energy storage system (BESS) at Parkes and a 25MW/50MWh BESS at Panorama within the suburb of Bathhurst. A 25MVa synchronous condenser and a brand new 132 kV transmission line are additionally amongst thought of choices which could possibly be picked as complementary to the battery techniques.

Within the North West Slopes, a 50MW/50MWh BESS has been proposed for development within the locality of Narrabri in addition to one other BESS of unspecified output and capability at Gunnedah substation. The North West Slopes plan additionally contains some transmission upgrades, which Transgrid stated could possibly be executed with minimal disruption by being place on current strains.

In every case, batteries had been chosen partly due to their potential to be constructed and commissioned a lot earlier than different proposals. The BESS could possibly be in place and in operation by a 2024-2025 timeline.

Aggressive solicitation set to start

A aggressive procurement course of will now be launched by the transmission operator and industrial negotiations carried out.

The Narrabri BESS might present roughly A$513 million (US$350.33 million) in internet advantages and the BESS at Gunnedah about A$496 million. The 2 BESS choices for Bathhurst, Orange and Parkes might present A$3,221 million and A$3,202 million in internet advantages, in response to Transgrid.

The announcement comes simply after the Australian Energy Market Operator (AEMO) forecast that batteries and different energy storage can be a serious participant in transitioning the NEM to low carbon energy within the coming many years.

By 2050, as coal declines in significance and disappears completely from the supply of base load energy to the NEM, the market’s firming capability combine would require 46GW/640GWh of dispatchable storage capacity, AEMO said.

This is able to be along with 7GW of current non-pumped hydro hydroelectric capability and a few 10GW of fuel technology, in response to AEMO’s Built-in System Plan (ISP) 30-year roadmap for the NEM.

Australia’s energy market is at the moment in disaster mode, with excessive electrical energy costs pushed by fuel worth volatility and outages at round 3GW of coal crops – though the latter scenario is believed to have been resolved. This comes because the nation experiences a few of its coldest winter climate for many years and for a few weeks final month AEMO temporarily suspended spot market trading in the NEM.

The scenario has pushed requires higher funding in renewables and storage – and for a national energy storage target policy.

As reported by the Sydney Morning Herald newspaper final week, there are additionally considerations for greater drilling for fossil fuels in the area around Narrabri.

Burns and McDonnell providing EPC for RWE


Engineering, procurement and construction (EPC) firm Burns & McDonnell is providing its services for Texas Waves II, a 30MW battery energy storage system (BESS) by RWE.

The 30MW, one-hour system in Scurry County will provide load shifting and grid support services according to a press release. It is expected to come online in late 2022 according to project owner RWE, the Germany-based global energy firm.

Burns & McDonnell described the project as a ‘standalone’ BESS, while in a press release last month that announced the installation of the project’s inverters, RWE said the unit was co-located with the existing Pyron Wind Farm. The EPC firm did say that the battery would charge from the wind farm.

Chris Ruckman, vice president of energy storage at Burns & McDonnell, said: “Adding battery storage in the ERCOT market will be a valuable asset for RWE as they continue supporting their customers with clean, reliable energy.”

ERCOT stands for the Electric Reliability Council of Texas, the grid operator for the majority of the Lone Star State.

Burns & McDonnell said the BESS consists of owner-provided CATL EnerOne battery racks populated with lithium iron phosphate (LFP) battery modules. CATL, based in China, is the largest lithium-ion battery manufacturer in the world today by units sold.

The EPC firm will provide all engineering services for the project, and will install the racks, medium-voltage power station (MVPS) and balance of system (BOS) equipment. The work also includes modifying the existing substation, including installation of a new 34.5-kV vacuum breaker, interconnection details, protective relaying and metering upgrades.

estonia pumped hydro energy storage


State-owned Estonian energy firm Eesti Energia is planning to construct a 225MW pumped hydro energy storage facility, as a part of a wider push to turn out to be unbiased of Russian energy.

The corporate has began finishing up preliminary design and environmental influence evaluation for the works which might be accomplished by 2025-26.

This implies it might be accomplished in time for the Baltic area together with Estonia’s deliberate connection to the continental electrical energy system – and concurrent disconnection from the Russian energy system – in 2026.

The pumped hydro energy storage plant is being deliberate for the commercial space of a now closed oil shale mine within the northeast county of Ida-Virumaa.

Eesti Energia stated it’s not conscious of disused mines getting used as reservoirs for pumped hydro wherever else, and that the idea might be exported to international locations whose land reduction makes standard pumped hydro energy storage tough.

The plan, illustrated within the above picture, is for the higher reservoir to be constructed on a tailings dam, an earth-fill embankment used to retailer byproducts of mining, whereas the closed mine underground will probably be used because the decrease reservoir.

The Baltic states are at present a part of Russia’s electrical energy system however are looking for to disconnect and synchronise with continental Europe’s by a connector between Poland and Lithuania, the Harmony Link project.

Lithuania can also be endeavor massive energy storage tasks as a part of this transfer, in its case building a 200MW, one-hour battery energy storage system (BESS) provided by Fluence. Poland, in the meantime, is building a 200MW/820MWh BESS which can help the deliberate synchronisation of the areas, the state-owned firm behind the challenge has stated.

Trying elsewhere, the pumped hydro energy space for storing has seen just a few substantial large-scale tasks commissioned just lately. Though small in quantity in comparison with BESS models, the scale of the tasks means every one has a big impact on the native grid.

A facility was recently inaugurated in Portugal by utility Iberdrola, whose 1,158MW mixed hydroelectric energy as soon as absolutely operational will enhance the nation’s electrical energy capability by 6%. In Switzerland, a 20GWh system in the Valais mountains also recently came online.

Australian flow battery company Redflow reports 172.3% jump in half-year revenues


Australia-based zinc-bromine stream battery firm Redflow, which has a market cap of practically US$60 million, has halted inventory market buying and selling because it prepares a capital elevate.

The ASX-listed firm introduced the halt right now (11 August) which can proceed till Monday 15 August or when it pronounces the capital elevate, whichever is sooner. It stated the cease in buying and selling was essential to make the announcement.

It has not but revealed how a lot it’s planning to boost however previous strikes, its present dimension and up to date statements could give a tough thought.

The corporate has a market capitalisation of UA$81 million (US$57 million) on the time of writing, and in July 2021 it raised AU$5 million from company finance agency New Expertise Capital Group.

And in an investor presentation launched concurrently with the buying and selling halt announcement, it stated it requires AU$6 million in extra capex to ramp up its Thailand manufacturing facility from 30MWh (finish 2022) to 80MWh by the top of 2023.

The presentation outlined the worth proposition for non-lithium batteries for lengthy period energy storage (LDES) and, extra particularly, its personal zinc bromine expertise.

The corporate claimed to be a frontrunner in medium period energy storage with 250-plus lively deployments with expertise in ‘multi-MWh’ scale, though its largest ever deployment is 2MWh, ordered in March last year by a waste-to-energy facility in California.

It cited commerce group LDES Council’s figures that say world cumulative LDES (outlined as eight hours-plus period) deployments may attain 85-140TWh by 2040, and stated the market is more and more wanting past lithium-ion to do that. It cited 1,124% and 106% will increase in lithium and cobalt costs respectively during the last yr and a half, versus simply 48% and 29% respective rises for zinc and bromine.

And throughout the stream battery house, Reflow claims its expertise has an energy and energy density as much as 3 times greater than iron stream, vanadium and different zinc-based batteries.

Its principal markets to-date have been Australia and the US and it serves these from a producing facility in Thailand which is about to finish 2022 with a 30MWh annual manufacturing capability. It expects this to extend to 80MWh by end-2023, for which the AU$6 million might be required.

Final week, the corporate introduced that it had gained a young to offer 180kWh of battery storage as principal provider to the Australian authorities’s Bureau of Meteorology emissions discount and reliability undertaking. Redflow will provide 18 of its 10kWh ZBM batteries to provide energy for crucial infrastructure.

Redflow saw revenue of AU$1,174,242 (US$833,000) in the second half of 2021, a 172% increase, as coated by Energy-Storage.information.
