Overview
- Measures modify operating procedures P.O. 3.1 (Programming), P.O. 3.2 (Technical Restrictions) and P.O. 7.2 (Secondary Regulation) with technical adjustments to limit market impact.
- The changes are time‑limited for 30 days to three months, and the regulator may suspend them early if they prove unnecessary or distort market functioning.
- Red Eléctrica de España must submit daily updates on implementation and effects and develop a coordinated action plan with sector participants.
- The CNMC has opened an information file on the abrupt voltage variations, requesting data from combined‑cycle plant owners and the system operator, with responses received between October 8 and 15.
- REE reported late‑September voltage swings linked to faster grid dynamics from power‑electronics‑connected generation such as renewables, noting potential disconnections despite values remaining within safety limits.
