Harmonised V2G Profitability Database: 589 Cases from 78 Studies (2000–2023)

This dataset contains study-level metadata and harmonised economic outcomes for 78 vehicle-to-grid (V2G) profitability studies published between 2000 and 2023, covering 589 cases across 17 countries. All monetary values are harmonised to real 2025 euros per electric vehicle per year through currency conversion (ECB annual average rates) and inflation adjustment (German electricity-sector producer price index). Each case is classified by market segment, participation structure, scheduling method, cost coverage, and vehicle and mobility assumptions. The dataset reports both revenue (before cost deductions) and profit (after study-specific cost deductions) where available.
