Energy storage prices vary depending on the system type and capacity1. As of Q1 2021, the cost benchmarks include:Residential PV systems: $2.65 per watt DC (WDC) or $3.05/WACCommercial rooftop PV systems: $1.56/WDC or $1.79/WACCommercial ground-mount PV systems: $1.64/WDC or $1.88/WACFixed-tilt utility-scale PV systems: $0.83/WDC or $1.13/WACOne-axis-tracking utility-scale PV systems: $0.89/WDC or $1.20/WACResidential PV system with 5 kW/12.5 kWh storage: $30,326-$33,618 [pdf]
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 ESS cost survey in 2017. Costs are expected to remain high in 2023 before dropping in 2024.
The cost categories used in the report extend across all energy storage technologies to allow ease of data comparison. Direct costs correspond to equipment capital and installation, while indirect costs include EPC fee and project development, which include permitting, preliminary engineering design, and the owner’s engineer and financing costs.
The cost estimates provided in the report are not intended to be exact numbers but reflect a representative cost based on ranges provided by various sources for the examined technologies. The analysis was done for energy storage systems (ESSs) across various power levels and energy-to-power ratios.
The capital cost, excluding EPC management fee and project development costs for a 100 MW, 8-hour tower direct33 thermal storage system after stripping off cost for CSP plant mirrors and towers was estimated at $295/kWh, of which $164/kWh (or $1312/kW) corresponds to power block costs operating on a steam cycle (Lundy, 2020).
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.
Economies of scale—driven by hardware, labor, and related markups—are evident here, as is the impact of costs spread over a larger number of watts. Figure 3 shows a soft cost reduction of 62% between a 3-kW and an 11-kW system. Hence, as system sizes increase, the per-watt cost to build systems decreases.

Accordingly, the average selling price is 2,006.79 VND/kWh (an increase by 4.5%). This is the second time in 2023 that an increase has been made. The new price applies from 9 November 2023..

On January 7, 2023, the ministry set the ceiling prices at 1,184.90 VND (5.05 cents) per kWh for ground-mounted solar projects, 1,508.27 VND (6.43 cents) for floating solar projects, 1,587.12 VND (. . The government is proposing a tariff of VND671 (US$0.024) per kWh for surplus power from the rooftop solar panels, with a proposed offtake volume of up to 10%. [pdf]
Vietnam’s Ministry of Industry and Trade (MIOT) recently introduced new ceiling prices for solar and wind projects that sell electricity to Electricity of Vietnam (EVN). The ceiling price for ground-mounted solar has been slashed from $0.0709/kWh to $0.0502/kWh, threatening the financial viability of large-scale solar projects.
The ceiling price for ground-mounted solar has been slashed from $0.0709/kWh to $0.0502/kWh, threatening the financial viability of large-scale solar projects. Vietnam’s Ministry of Industry and Trade (MIOT) has set new price ceilings for the so-called “transitional” wind and solar projects.
On 7 January 2023, the Vietnam Ministry of Industry and Trade announced new ceiling prices for solar and wind energy in the country, pursuant to which Vietnam Electricity (“ EVN ”) can now negotiate tariffs in relation to transitional solar and wind energy projects in accordance with Circular 15/2022/TT-BCT (“ Circular 15 ”).
However, the current Vietnamese solar PV market is estimated to be only around 5 MWp, with 80% off-grid applications in rural areas. Solar energy is not yet integrated into political energy development strategies, such as the national Power Development Plan (PDP).
In 2021, the data showed that Vietnam now has 16.5 GW of solar power. This was accompanied by its green energy counterpart wind at 11.8 GW. A further 6.6 GW is expected in late 2021 or 2022. Ambitiously, the government plans to further bolster this by adding 12 GW of onshore and offshore wind by 2025.
Solar energy in Vietnam is available all year round, is rather stable and distributed widely over different eco-geographical areas. Solar energy, especially in the southern and central regions can be used on average 300 days per year. It can be exploited to meet the two main demands: thermal and electrical power (To Quoc Tru, 2010).
