expanded), has already fallen to about US$300/ kWh and the price tag today may be about half that in 2017.
Looking ahead, battery costs may depend very much upon the cost of metals and of fossil fuels used in mining.
The future
All numbers quoted above are for actual wind generation for six European countries in 2015. In 2015, these six countries had 103 GW of wind capacity while 20 European countries had 146 GW installed capacity. Adjusting wind capacity figures
to “all Europe” and projecting growth to 2050 suggests that storage figures presented above may have to be increased by a factor of ~10. This seems neither physically feasible, environmentally desirable nor affordable. Is current energy policy predicated upon an impossible dream?
Neoen’s next big Australian battery under construction
Construction is underway on yet another Neoen big battery in Australia, the 100 MW/200 MWh Capital Battery, located next to TransGrid’s Queanbeyan substation, in the Australian Capital Territory (ACT). Doosan is EPC contractor and operation is expected in the first half of 2023. Doosan GridTech’s Intelligent Controller®
will
orchestrate energy arbitrage, fast frequency response, and ancillary services, with the potential to provide synthetic inertia or black start services in the future.
In line with Neoen’s develop-to-own business model, it will be the long-term owner and
operator of the facility and once operational will launch a Community Co-investment Scheme, providing residents of the ACT and Capital region with an opportunity to become financial stakeholders in the project.
The Capital Battery takes Neoen’s Australian battery storage portfolio to 576 MW in operation or under construction, “cementing its position as the country’s leading owner and operator of big batteries”, the company says.
Neoen also owns and operates the recently completed 300 MW/450 MWh Victorian Big Battery in Geelong (pictured), and the
Neoen contract for Saft
Saft has been awarded a contract by Neoen to deliver a turnkey 8MW/8MWh energy storage system (ESS) to be sited at Antugnac (southern France).
The facility, which includes four Intensium Max 20 containers, will be the first collocated ESS and solar farm connected to RTE’s French HV transmission grid, Saft says.
It will primarily deliver frequency regulation, enabling Neoen to meet the requirements of a 7-year contract awarded to Neoen under RTE’s AOLT (Long Term Call for Tenders) scheme.
It will also be used to provide other services to optimise revenue over the coming 15 years. Throughout this period, “Saft guarantees very
high levels of availability and performance, adapting to changing operation patterns and enabling – if needed – more than two full discharges per day”, the company says. Saft is building the new energy storage system on an EPC basis, with completion scheduled for spring 2022, within 10 months of contract signing.
Wärtsilä enters the Dutch market with the country’s biggest energy storage
Wärtsilä is to supply a 25 MW/48 MWh energy storage system to GIGA Storage BV in the Netherlands to help stabilise the electric grid. This will be Wärtsilä’s first energy storage project in the Netherlands and it will be the country’s largest system to date. The system is expected to become operational in October 2022. The Wärtsilä energy storage system, known as
the GIGA Buffalo battery, will be co-located with wind and solar assets as part of the Widnet smart grid, located at the Wageningen University & Research test centre, Lelystad.

Eneco plans to use the battery to make its energy services more sustainable and add more renewable energy to the grid. The energy storage will also help to optimise the power system, regulate frequency and and improve revenues. The Dutch government’s goal is to reduce greenhouse gas emissions by 49% by 2030 and 95% by 2050. The growth of renewable energy in the Netherlands and likewise across Europe has helped to decarbonise the energy system but has also created congestion on electrical networks, making energy storage a necessity for reliability, says Wärtsilä. Recent reports indicate that the Netherlands will need between 29 and 54 GW of energy storage capacity by 2050. “Wärtsilä sees a major opportunity and

paramount need to help our customers increase energy storage deployment throughout Europe in order to realise a 100% renewable energy future,” said Pekka Tolonen, Director, Europe, Wärtsilä Energy.
The Buffalo battery will be the first large-scale energy storage project based on lithium iron phosphate (LFP) chemistry in Europe, which provides enhanced safety features and uses “less vulnerable natural resources”, says Wärtsilä. The project scope will include Wärtsilä’s GridSolv Quantum, a fully integrated, modular and compact energy storage system, as well as the GEMS Digital Energy Platform, Wärtsilä’s energy management system. It will be optimised with Wärtsilä’s Service+ GAP solution, which provides maintenance with performance guarantees. Wärtsilä will supply the energy storage system under an extended equipment delivery and long-term service agreement.
150 MW/193.5 MWh Hornsdale Power Reserve in South Australia. Neoen notes that the ACT project takes it “one step closer to its goal of having at least one large-scale battery operating in each state of Australia’s National Electricity Market.”
