6 FAQs about [Storage energy to meet peak summer demand]
What is the future of energy storage?
But measuring the value of energy storage is inherently complex—and future systems will likely include multiple storage technologies, adding new complexity. To answer the big questions around the role of storage in our future grid, the National Renewable Energy Laboratory (NREL) has launched the multiyear Storage Futures Study (SFS).
Is energy storage cost-competitive?
The Storage Futures Study considers when and where a wide range of storage technologies are cost-competitive, depending on how they are operated and what services they provide for the grid. With declining costs, improved technologies, and increasing deployment, energy storage is poised to become a growing part of the evolving U.S. power system.
What are the opportunities for battery storage with 4-hour durations?
NREL analysts found significant opportunities for batteries with 4-hour durations. In this phase, the cost-competitiveness of battery storage increases with hybrid system configurations, where storage is co-located with renewable generation sources, particularly solar photovoltaics, to receive an investment tax credit.
Where does heating demand increase in the winter?
Unlike the peak cooling demand intensity, there are no areas with large increases and the trends are significant mostly in Southern California and the southwest and southeast portions of the CONUS, which are regions where the heating demand during the winter is low and does not dominate grid operations.
How does peak load affect heating utilization rates?
Once completed, however, the infrastructure built to meet the peak load may see lower utilization rates in the northern parts of the United States driven by decreases in the mean heating demand (Fig. 1), which are larger than the decreases in peak demand (Fig. 3).
Is there a north-south divide in thermal demand trends?
We identify a north-south divide in the emergent patterns of the heating, cooling, and total thermal demand trends, especially for the ratio of average to peak demands and the relative importance of the peak cooling and peak heating demand.
