The main objective of this study is to investigate the role of energy storage and demand response in Chinese power structure transition with high penetration of renewable
on of new energy power system continues to increase, and has a high impact on security. In this context, this paper carries out a demand analysis, firstly discussing the demand for large-scale energy storage in the development of new energy for power system, and secondly analyzing the demand for large-scale energy storage in the safe operation
While for 100% renewables energy systems (power, heat, mobility), it can remain below 6% of the annual energy demand. Combination of sectors and diverting the electricity to another sector can play a large role in reducing the storage size.

A recent McKinsey study reveals an 800% increase in corporate PPAs (Power Purchase Agreements) with storage components since 2021 – companies now view energy security like they view cybersecurity: "Can''t afford to ignore it until the lights go out."
Emphasising the pivotal role of large-scale energy storage technologies, the study provides a comprehensive overview, comparison, and evaluation of emerging energy storage solutions, such as lithium-ion cells, flow redox cell, and compressed-air energy storage.
How does storage affect the economic value of electricity? The study''s key findings include: The economic value of storage rises as VRE generation provides an increasing share of the electricity supply.
While energy storage modifies the power supply curve, demand response operates similarly on the demand side by altering the power load curve. However, its low cost-effectiveness limits widespread adoption.
The addition of power supplies with flexible adjustment ability, such as hydropower and thermal power, can improve the consumption rate and reduce the energy storage demand. 3.2 GW hydropower, 16 GW PV with 2 GW/4 h of energy storage, can achieve 4500 utilisation hours of DC and 90% PV power consumption rate as shown in Figure 7.
The results of this study emphasize and support the future application and promotion of energy storage and demand response in national power structure transition compared to micro-grid studies.
When the demand response period is within 8am-8pm, energy storage and demand response facilitate a reduction in transmission line deployment. And the expansion of transmission lines reduces the deployment of energy storage and increases in usage in demand response.
Based on these, for power systems with up to 95% renewables, the electricity storage size is found to be below 1.5% of the annual demand (in energy terms). While for 100% renewables energy systems (power, heat, mobility), it can remain below 6% of the annual energy demand.
The deployment of energy storage and demand response facilitates the retirement of thermal units, leading to the decommissioning of over 150 GW of coal-fired plants and a reduction of more than 100 GW in CCS installations by 2050, with energy storage accounting for the majority of this impact.
