The National Renewable Energy Laboratory's (NREL's) Storage Futures Study examined energy storage costs broadly and specifically the cost and performance of LIBs (Augustine and Blair, 2021). The costs presented here (and for distributed residential storage and distributed commercial storage) are based on this work. This work incorporates base year battery costs and breakdowns from (Ramasamy et al., 2021), which works from a bottom-up cost model. We would note though that, during the elapsed time between the calculations for the Storage Futures Study and this ATB release, updated values have been calculated as more underlying data have been collected. Though these changes are currently small, we recommend using the data presented here in the ATB rather than what was previously published with the Storage Futures Study.
Base year costs for utility-scale battery energy storage systems (BESS) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2021). The bottom-up BESS model accounts for major components, including the LIB pack, inverter, and the balance of system (BOS) needed for the installation. Using the detailed NREL cost models for LIB, we develop base year costs for a 60-MW BESS with storage durations of 2, 4, 6, 8, and 10 hours, shown in terms of energy capacity ($/kWh) and power capacity ($/kW) in Figure 1 and Figure 2 respectively. Base year installed capital costs for BESS in terms of $/kWh decrease with duration, and costs in $/kW increase. This inverse behavior is observed for all energy storage technologies and highlights the importance of distinguishing the two types of battery capacity when discussing the cost of energy storage.
In all three scenarios of the scenarios described below, costs of battery storage are anticipated to continue to decline. The Storage Futures Study (Augustine and Blair, 2021) describes that the majority of this cost reduction comes from the battery pack cost component with minimal cost reductions in BOS, installation, and other components of the cost. The report indicates that NREL, BloombergNEF (BNEF), and others anticipate that the growth of the overall battery industry - across the consumer electronics sector, the transportation sector, and the electric utility sector - will lead to cost reductions. Additionally, BNEF and others indicate that changes in lithium-ion chemistry (such as switching away from cobalt) will also reduce cost. A third key factor is ongoing innovation with significant corporate and public research on batteries. Finally, the growth in the market (effective learning-by-doing) and more diversity of chemistries will expand and change the dynamics of the supply chain for batteries resulting in cheaper inputs to the battery pack (Mann et al., 2022).
Projected Utility-Scale BESS Costs: Future cost projections for utility-scale BESS are based on a synthesis of cost projections for 4-hour duration systems in (Cole et al., 2021) and the BNEF cost projections for utility-scale BESS (BNEF, 2019b)(Frith, 2020). The Cole et al. cost projections are based on a literature survey that includes results from 13 studies of BESS costs. The BNEF cost projections are based on learning rates and deployment projections for utility-scale BESS that are broken down at the system component level. Both projections extend to 2050.
Definition: The bottom-up cost model documented by (Ramasamy et al., 2021) contains detailed cost components for battery only systems costs (as well as combined with PV). Though the battery pack is a significant cost portion, it is a minority of the cost of the battery system. These costs for a 4-hour utility-scale stand-alone battery are detailed in Table 1.
Future Projections: Future projections are based on the same literature review data that inform (Cole et al., 2021) , which generally used the median of published cost estimates to develop a Moderate Technology Cost Scenario and the minimum values to develop an Advanced Technology Cost Scenario. However, as the battery pack cost is anticipated to fall more quickly than the other cost components (which is similar to the recent history of PV system costs), the battery pack cost reduction is taken from (BNEF, 2019b) and (Frith, 2020) and is reduced more quickly. This tends to make the longer-duration batteries (e.g., 10 hours ) decrease more quickly while shorter-duration batteries (e.g., 2 hours) decrease less quickly into the future. All durations trend toward a common trajectory as battery pack costs decrease into the future.
Base Year: (Cole et al., 2021) assume no variable O&M (VOM) costs. All operating costs are instead represented using fixed O&M (FOM) costs. The fixed O&M costs include battery replacement costs, based on assumed battery degradation rates that drive the need for 20% capacity augmentations after 10 and 20 years to return the system to its nameplate capacity (Ramasamy et al., 2021). The augmentations assume that 20% of the cells are replaced in each augmentation, with costs for battery cells and bidirectional inverters dropping 40% in the next 20 years. In the 2022 ATB, FOM is defined as the value needed to compensate for degradation to enable the battery system to have a constant capacity throughout its life. According to the literature review (Cole et al., 2021), FOM costs are estimated at 2.5% of the capital costs in dollars per kilowatt. Items included in O&M are shown in the table below.
The cost and performance of the battery systems are based on an assumption of approximately one cycle per day. Therefore, a 4-hour device has an expected capacity factor of 16.7% (4/24 = 0.167), and a 2-hour device has an expected capacity factor of 8.3% (2/24 = 0.083). Degradation is a function of this usage rate of the model and systems might need to be replaced at some point during the analysis period. We use the capacity factor for a 4-hour device as the default value for ATB due to anticipation that 4-hour durations are more typical in the utility-scale market.
Hello Welcome to the Canon Forums and thanks for your inquiry!
The EOS 1100D is known in the US by the name Rebel T3. This camera is compatible with the AC Adapter Kit ACK-E10. With the AC Adapter Kit you can power your camera by household power and not have to worry about the remaining battery power.
I still need the camera too be hooked up to the computer and connected to EOS Utility at all time. It cannot be disconnected from the PC. That's why im looking for a way to either charge the battery while the camera is connected to the PC or find a way to run the camera on power directly from the computer
The camera can run on an AC adapter while its battery is being charged. Why would that require it to be disconnected from the PC? To put it another way, the PC has no way of knowing, nor reason to care, that the camera isn't operating on its battery.
Depending on the battery and how much you are using it, batteries can provide power for several hours, or longer. Battery storage can be an important component of a more robust emergency preparedness plan in the event of a power outage.

Instead of building more power lines like most utilities to accommodate new clean energy and prevent outages, GMP is taking a different approach. The plan for its 2030 Zero Outages Initiative, which it filed with state regulators yesterday, is to make its existing power lines more resilient, bury power lines, and install residential battery storage for all of its customers.
The first phase of the filing calls for an investment of $250 million to storm harden and bury power lines and $30 million for battery storage. The second phase will seek approval to accelerate and expand beyond 2026.
I wish our for profit California utility PG&E would consider such initiatives instead of proposing sticking customers with connection fees that would result in hundreds of dollars PER month added to monthly bills, depending on income. This would seriously disincentivize solar and energy efficiency.
