In light of this, Zelce said CEIG supports a change to a minimum duration of 4 hours, but advocates for a "more nuanced approach to addressing the need for storage longer than 4 hours". CEIG stressed that even if the negotiation results in a reduction of storage duration to 4 hours, support for longer durations should not be weakened.

6 FAQs about [Energy storage 4 hours 2 hours]

Should energy storage be more than 4 hours of capacity?

However, there is growing interest in the deployment of energy storage with greater than 4 hours of capacity, which has been identified as potentially playing an important role in helping integrate larger amounts of renewable energy and achieving heavily decarbonized grids.1,2,3

Can 4 hour storage meet peak demand?

The ability of 4-hour storage to meet peak demand during the summer is further enhanced with greater deployments of solar energy. However, the addition of solar, plus changing weather and electrification of building heating, may lead to a shift to net winter demand peaks, which are often longer than can be effectively served by 4-hour storage.

Will 4 hour storage drop over time?

On the value side, the value of 4-hour storage is likely to drop over time as many regions in the United States shift to net winter peaks. This would increase the relative value of longer-duration storage that would be needed to address the longer evening peak demand periods that cannot be served directly with solar energy.

Will a fifth hour of battery storage cost more than 4 hours?

value for a fifth hour of storage (using historical market data) is less than most estimates for the annualized cost of adding Li-ion battery capacity, at least at current costs.25 As a result, moving beyond 4-hour Li-ion will likely require a change in both the value proposition and storage costs, discussed in the following sections.

Is 4 hour storage a good option for summer peaks?

Historically, 4-hour storage has been well-suited to providing capacity during summer peaks in many U.S. regions, which has led to several wholesale market regions adopting a “4-hour capacity rule.”

Will a 4 hour solar system increase storage capacity during summer peaks?

Overall, while continued deployment of solar can maintain the ability of 4-hour storage to provide significant capacity during summer peaks, this solar deployment will also accelerate the shift to net winter peaks in much of the country. This then will likely drive the decline in capacity value of 4-hour storage and incentivize longer durations.
