Projections of utility-scale PV plant CAPEX for 2035 are based on bottom-up cost modeling, with 2022 values from (Ramasamy et al., 2022) and a straight-line change in price in the
Executive Summary In this work we document the development of cost and performance projections for utility-scale lithium-ion battery systems, with a focus on 4-hour duration
Such challenges are minimized by the incorporation of utility-scale energy storage systems (ESS), providing flexibility and reliability to the electrical system. Despite the
As of the first half of 2023, the world added 27.3 GWh of installed energy storage capacity on the utility-scale power generation side plus the C&I sector and 7.3 GWh in
European Market Outlook for Battery Storage 2025-2029 7 May 2025 The report explores trends and forecasts across residential, commercial & industrial (C&I), and utility
In this way, the cost projections capture the rapid projected decline in battery costs and account for component costs decreasing at different rates in the future. Figure 3 shows the resulting utility-scale BESS future cost projections for the
Apart from above utility-scale applications, customer-side ESS are also attractive to commercial, industrial, and residential customers for the usefulness of these ESS in
Energy storage system costs stay above $300/kWhfor a turnkey four-hour duration system. In 2022,rising raw material and component prices led to the first increase in energy storage
Current projections indicate that utility-scale battery storage costs will continue to decrease by 8-10% annually through 2030, driven by increased production volumes and ongoing technological innovations.

Energy storage system costs stay above $300/kWh for a turnkey four-hour duration system. In 2022, rising raw material and component prices led to the first increase in energy storage system costs since BNEF started its
Executive Summary In this work we describe the development of cost and performance projections for utility-scale lithium-ion battery systems, with a focus on 4-hour duration
Solar PV inverter cost, however, typically underestimates PCS cost by approximately 20% (Baxter, 2020a; Vartanian, 2020). Discussions with a PCS vendor indicated a typical cost of
Compared to 2022, the national laboratory says the BESS costs will fall 47%, 32% and 16% by 2030 in its low, mid and high cost projections, respectively. By 2050, the costs could fall by 67%, 51% and 21% in the three
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.
This broadly matches up with recent analysis by BloombergNEF which found that BESS costs have fallen 2% in the last six months, as well as anecdotal evidence of reductions after spikes in 2022. Compared to 2022, the national laboratory says the BESS costs will fall 47%, 32% and 16% by 2030 in its low, mid and high cost projections, respectively.
A big driver of the fall in BESS costs will be a decline in the costs of the battery cells and packs themselves, which can make up half the cost of a lithium-ion BESS.
The most important takeaway is that the NREL estimates that BESS costs will start to fall this year in its ‘low’ and ‘mid’ cost projections, with an increase over the next few years forecast in its ‘high’ scenario, visualised in the graph above.
In early 2024, the price of residential BESS offered to end consumers in Europe ranged widely, from €400 to more than €1,200 per kilowatt-hour (kWh) (Exhibit 2). Historically, European OEMs built trust-based brands by highlighting their “made in Europe” status and rode the first-mover wave over the past ten years.
Several factors can influence the cost of a BESS, including: Larger systems cost more, but they often provide better value per kWh due to economies of scale. For instance, utility-scale projects benefit from bulk purchasing and reduced per-unit costs compared to residential installations. Costs can vary depending on where the system is installed.
