Overall the real cost per kWh of energy discharged by a battery storage system is approximately 15p to 30p per kWh for most systems, with lithium-ion coming out strongly on top due to its long life.
In order to accurately calculate power storage costs per kWh, the entire storage system, i.e. the battery and battery inverter, is taken into account. The key parameters here are the discharge depth, system efficiency [%] and energy content [rated capacity in kWh]. ??? EUR/kWh Charge time: ??? Hours
Given the range of factors that influence the cost of a 1 MW battery storage system, it's difficult to provide a specific price. However, industry estimates suggest that the cost of a 1 MW lithium-ion battery storage system can range from $300 to $600 per kWh, depending on the factors mentioned above.
The lifetime cost of small scale battery storage is now around 13p per kWh. This is the cost 'per cycle' of charging and discharging 1 kWh (excluding the cost of the electricity used to charge the battery). In the residential arena, battery storage is starting to make sense in two applications:
However, a more precise way to assess their value is by using the £/kWh metric, which stands for price per kilowatt-hour of storage. This pricing can vary between £265 and £415 per kWh. The more affordable options often come from Chinese importers, while the higher end of the spectrum features premium brands like Tesla from the United States.
This study shows that battery electricity storage systems offer enormous deployment and cost-reduction potential. By 2030, total installed costs could fall between 50% and 60% (and battery cell costs by even more), driven by optimisation of manufacturing facilities, combined with better combinations and reduced use of materials.
Developer premiums and development expenses - depending on the project's attractiveness, these can range from £50k/MW to £100k/MW. Financing and transaction costs - at current interest rates, these can be around 20% of total project costs. 68% of battery project costs range between £400k/MW and £700k/MW.
