Real Cost Behind Grid-Scale Battery Storage: 2024 European Market
Industry projections suggest these costs could decrease by up to 40% by 2030, making battery storage increasingly viable for grid-scale applications. The European market stands at a
ESSOP has explored two ways in which ports can minimize their energy costs by using energy storage: • Optimising how to use PV solar generation to offset grid electricity. The wholesale price of energy varies every half-hour, and on a time-of-day tariff this variation is passed onto users.
The largest component of utility-scale battery storage costs lies in the battery cells themselves, typically accounting for 30-40% of total system costs. In the European market, lithium-ion batteries currently range from €200 to €300 per kilowatt-hour (kWh), with prices continuing to decrease as manufacturing scales up and technology improves.
Ensuring availability of these electrical resources to meet loads which are intermittent and uncertain is becoming a critical port function. It requires investment in multi-vector energy supply chains, energy storage in ports and their associated energy management systems.
Energy storage is also needed to optimize utilization of in-port generation and avoid curtailment when generation exceeds the available demand. However, it is unclear how much PV solar generation and associated energy storage would achieve a minimum levelized cost of energy.
