New cost-of-electricity data from the OECD Nuclear Energy Agency quantifies the economics of standalone four-hour lithium-ion battery storage in Austria, giving C&I buyers a reference point for grid-scale and behind-the-meter comparisons.
The NEA’s 2025 edition of The Costs of Generating Electricity, published in September 2026, models a standalone four-hour lithium-ion BESS in Austria with an overnight construction cost of US$865 per kW and a levelised cost of storage (LCOS) of US$109.79 per MWh, based on a 100 MW reference plant running at a 17% capacity factor.
The same dataset puts solar-plus-storage reference systems in Austria at a levelised cost of electricity (LCOE) of US$72.07 per MWh for a 150 MW PV array paired with 100 MW / 400 MWh of storage. These figures are modelling references rather than project quotes, but they anchor the cost conversation for commercial buyers weighing storage against grid imports.
Austria’s storage market remains smaller than Germany’s or the Netherlands’, but the cost data reinforces a broader European trend: four-hour lithium-ion storage has crossed the threshold where it competes directly with peak grid power in many markets, even before subsidy.
