The company has submitted a document to the Comisión Nacional de los Mercados y la Competencia (CNMC) requesting that proposed amendments be subjected to public consultation before final approval. The company warns that the recorded changes “could cause consumption and production shutdowns that ultimately destabilize the electrical system.”
Following the electricity blackout on April 28 in Portugal and Spain, the system operator notes that the tensions observed in the last fifteen days occur “within the established limits.”
The company links these variations to sudden changes in production schedules, particularly in renewable energy generation, as well as to the response time of plants responsible for dynamic voltage control.
Even though they are “within” the defined parameters, these fluctuations “could impact supply security if the proposed changes are not implemented.” For this reason, Red Eléctrica requests urgent, “temporary and exceptional” approval of various system operation procedures.
The presented proposal foresees implications in scheduling processes, technical constraints, secondary regulation, and voltage control.
The operator proposes modifying the system’s technical constraints to reduce real-time energy imbalance.
With this change, the aim is to require scheduled production groups to reserve their full capacity for offering in balancing markets, preventing installations from reducing reserved power in intra-day markets.
The plan also includes control measures and adjustments in the process for validating compliance with voltage control service.
The amendment proposal will be submitted to public consultation until October 15 and will be in effect for a period of 30 consecutive days, extendable at the operator’s request, in additional periods of up to 15 days.
