First, we conducted a meta-analysis of existing literature on AI applications across the source-grid-load-storage segments to establish intervals for electricity saving potential. Second, these intervals serve as the empirical basis for defining three AI electricity saving scenarios, which are then used to calculate total electricity savings. Third, the electricity consumption of AI itself is estimated based on the technical parameters of AIDCs under varying demand scenarios. Finally, by cross-combining the three electricity saving scenarios with the three electricity consumption scenarios, we constructed a 3\u00d73 matrix of integrated scenarios and calculated the net electricity saving trend from 2025 to 2060.<\/p>\n<p>Fig. 6: Methodological framework of the study.<img decoding=\"async\" aria-describedby=\"figure-6-desc ai-alt-disclaimer-figure-6-1\" src=\"https:\/\/www.europesays.com\/ai\/wp-content\/uploads\/2026\/05\/44458_2026_80_Fig6_HTML.png\" alt=\"Fig. 6: Methodological framework of the study.\" loading=\"lazy\" width=\"685\" height=\"567\"\/>The alternative text for this image may have been generated using AI.<\/p>\n<p>It outlines a four-step process: meta-analysis for metric extraction (Step 1), scenario construction for electricity savings (Step 2), scenario construction for electricity consumption (Step 3), and trend forecasting through combined scenarios for 2025\u20132060 (Step 4).<\/p>\n<p>Study object<\/p>\n<p>To precisely evaluate the heterogeneous impacts of AI technologies on electricity saving across different power system, this study employs a multi-case comparative design.

The aim is to obtain a unified electricity saving OE for each segment, namely source, grid, load, and storage, which is then employed as the core parameter in the provincial net electricity saving assessment model. In this study, the OE represents the synthesized electricity saving effect of AI applications in the power system. Specifically, OE is obtained by aggregating electricity saving rates reported in individual studies using a standard meta-analysis approach, where each study is weighted according to its variance and sample size. This enables a unified quantitative estimate of the electricity saving potential of AI across heterogeneous applications. The meta-analysis procedure involves literature collection, classification of AI applications across the source-grid-load-storage segments, standardization of OE, heterogeneity assessment, pooling via random or fixed effects models, robustness testing, and bias adjustment. The specific steps are as follows.<\/p>\n<p>Step 1: Literature retrieval and classification of source-grid-load-storage<\/p>\n<p>A comprehensive and systematic search was carried out in major databases, namely Web of Science, IEEE Xplore, and CNKI, spanning the time frame from 2014 to 2024.

Specifically, TD adopts 20% efficiency improvement, which represents the upper-bound of hardware enhancement. PC assumes moderate improvements (10\u201315%), which are supported by policy incentives.

The preceding section introduced these scenarios in a brief. This subsection provides a detailed exposition of the quantification and parameterization methods applied to each scenario, along with the empirical evidence supporting their formulation.<\/p>\n<p>First, based on a meta-analysis, the quantified electricity saving ranges for different application practices were determined, as presented in Table\u00a0<a data-track=\"click\" data-track-label=\"link\" data-track-action=\"table anchor\" href=\"http:\/\/www.nature.com\/articles\/s44458-026-00080-4#Tab2\" rel=\"nofollow noopener\" target=\"_blank\">2<\/a>. From the literature collected in meta-analysis, the lower limit, median, and upper limit of electricity saving performance for each application type were extracted. These three statistical values served as the foundational benchmarks for the Inefficient, Typical, and Efficient scenarios, respectively. The threshold for the Efficient scenario in 2060 was established based on existing studies<a data-track=\"click\" data-track-action=\"reference anchor\" data-track-label=\"link\" data-test=\"citation-ref\" title=\"Mansoor, M. et al.

Subsequently, the benchmarks corresponding to the Efficient and Typical scenarios were adopted as the thresholds for the Typical and Inefficient scenarios in 2060, respectively. Finally, integrating these benchmarks with the technology maturity curve, the electricity saving rates for each scenario and each electricity saving measure were projected from 2025 to 2060.
