- Resolution 434/2025 is in force from November 1, 2025 to April 30, 2026, setting higher wholesale energy prices for residential users than for large consumers during the summer period.
- November electricity bills reflected initial increases, with an average rise of about 3.8% nationwide and a 3.4%–4.1% bump for households in the Buenos Aires metropolitan area.
- Large users see smaller changes or declines, with reported outcomes ranging from roughly a 2.2% increase to a 10.3% reduction, depending on usage and category.
- Outlets cite differing PEE bands attributed to the resolution, with La Nación reporting $63,443–$66,374 per MWh for households and $47,940–$49,496 for large users, while Página/12 reports $56,054–$58,281 and $47,310–$51,633 respectively.
