The residential electricity price in Iceland is ISK 25.756 per kWh or USD 0.203. The electricity price for businesses is ISK 12.470 kWh or USD 0.098. These retail prices were collected in March 2025 and include the cost of power, distribution and transmission, and all taxes and fees. Compare Iceland with 150 other countries.
of electric energy per year. Per capita this is an average of 50,669 kWh. Iceland can completely be self-sufficient with domestically produced energy. The total production of all electric energy producing facilities is 20 bn kWh, also 103 percent of own requirements.
Residents of Iceland have noticed a steep increase in their power bills since 2020. Iceland has been able to take advantage of the local environment to generate significant amounts of energy from renewable resources.
The results indicated that mechanical energy storage systems, namely PHS and CAES, are still the most cost-efficient options for bulk energy storage. PHS and CAES approximately add 54 and 71 €/MWh respectively, to the cost of charging power. The project׳s environmental permitting costs and contingency may increase the costs, however.
Base year costs for utility-scale battery energy storage systems (BESSs) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2023). The bottom-up BESS model accounts for major components, including the LIB pack, the inverter, and the balance of system (BOS) needed for the installation.
In terms of TCC (total capital cost), underground CAES (with 890 €/kW) offers the most economical alternative for bulk energy storage, while SMES and SCES are the cheapest options in power quality applications. However, the cost data for these electro-magnetic EES systems are rather limited and for small-scale applications.
PCS costs of the EES system are typically explained per unit of power capacity (€/kW). Energy related costs include all the costs undertaken to build energy storage banks or reservoirs, expressed per unit of stored or delivered energy (€/kWh).
The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.
Recent contracts are predominantly for much larger transmission-connected energy storage projects. Earlier energy storage contracts were significantly more expensive across all grid domains, and they generally reflect the cost reductions seen in the global storage industry.
Non-battery systems, on the other hand, range considerably more depending on duration. Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours.
Cost metrics are approached from the viewpoint of the final downstream entity in the energy storage project, ultimately representing the final project cost. This framework helps eliminate current inconsistencies associated with specific cost categories (e.g., energy storage racks vs. energy storage modules).
