How much does storing electricity cost?
Figure 3 depicts the overall costs of storing electricity in new plants or devices for various storage systems for the year 2018, including costs for capital, electricity, and operating and maintenance (O&M). As observed, a huge range exists for the spread of the overall costs—from about 8 cents/kWh up to close to 1 EUR/kWh.
Do market-based storage technologies compete with electricity prices?
All market-based storage technologies have to prove their performance in the large electricity markets or if applied decentralized, the (battery) systems compete with the electricity prices at the final customers level when the battery costs are also taken into consideration.
Does storage reduce the cost of electricity?
In general, they conclude that storage provides only a small contribution to meet residual electricity peak load in the current and near-future energy system. This results in the statement that each new storage deployed in addition to the existing ones makes the price spread smaller, see Figure 16, and, hence, reduces its own economic benefits.
