Spanish regulator sets return of 6.58% for electricity grids in 2026-2031

The Spanish competition watchdog approved rules that set the financial return on power?grid activity at 6.58% over the next six years. It said it was trying to balance the needs of network?investment with the protection of consumers.

The massive blackout which hit Spain and Portugal in April has reignited the debate on investment and return on investments. Power companies invest in grids for a guaranteed return, and consumers pay this rate via their electricity bills.

The CNMC said in a late-night statement that the financial remuneration 'rate for electricity transmission system operation and distribution 'would increase by 100 % from 5.58% for the previous six year period.

The watchdog has also released guidelines for calculating the remuneration of electricity distribution. This is to improve network quality and efficiency, reduce losses, and provide incentives for electrification.

CNMC stated that the distribution method aligns with government limits on investment by remunerating auditored investments?upto 0.13% gross domestic product.

The?regulator stated that it used a "guarantee based and participatory process" in making its decision. This included seven public consultations and five public hearings. It also sought the opinion of Spain's Energy Ministry on five separate occasions.

In recent years, energy groups like?Iberdrola or Enel have focused more on upgrading and expanding power grids while being selective about renewable energy projects. (Reporting and editing by David Latona)
