What's a short explanation of the discrepancy in EU wholesale vs household electricity price changes, over the period 2019-2025? Wholesale increased 30% YoY 2025 over 2024 but household didn't. Realistically we should compare to 2019 (pre-Covid, pre-inflation, pre-Ukraine war). Many individual EU govts implemented retail caps, (sales) tax cuts, and transfers. Where is this summarized at-a-glance, by country, by year?
