Red Eléctrica de España

What Red Eléctrica de España does

Red Eléctrica de España S.A.U. (REE) is Spain's designated Transmission System Operator (TSO), a role it has held exclusively since 1985 as a wholly-owned subsidiary of Redeia Corporación S.A., a publicly listed Spanish infrastructure group. REE manages Spain's 46,000 km of high-voltage electricity transmission grid (220 kV and 400 kV) and operates the national electricity system through two core control centers: CECOEL (Centro de Control Eléctrico), which runs 24/7/365 managing grid operations and supply security, and CECRE (Centro de Control de Energías Renovables), established in 2006 as the world's first control center dedicated exclusively to renewable energy integration. The company maintains 98.38% network availability and has integrated renewables to a 56.6% share of Spain's electricity mix, while also operating the Salto de Chira pumped-storage facility in Gran Canaria for non-peninsular system decarbonization.

REE serves the entire Spanish electricity ecosystem through regulated transmission tariffs and system-operation services, with customers spanning generators (renewable and conventional), distribution network operators, electricity commercializers, large industrial consumers, battery energy storage operators, EV charging point operators, and government bodies. Revenue is derived from CNMC-regulated transmission network usage charges, system operation services (balancing, ancillary, and adjustment), administration of the €9 billion Spanish capacity market scheme (€900M annually over 10 years from May 2026), and the SRAD active demand-response balancing mechanism (1,775 MW allocated for H2 2026 at €42.62/MW/hour). Public-facing platforms include eSIOS for market data, redOS mobile app for real-time system data, REVE for EV charging point mapping, and a self-consumption observability platform developed with Ingeteam.

The company is executing a major infrastructure build-out with €13.59 billion in planned grid investment and a national target of 22.5 GW of energy storage capacity by 2030 (up from 8.15 GW as of February 2026). The April 28, 2025 Iberian Peninsula blackout — affecting 60 million people across Spain and Portugal — prompted reinforced operational measures costing €422 million; the ENTSO-E expert panel's final report (March 2026) found no fault attributable to REE. REE is currently defending against a CNMC sanctioning procedure while simultaneously driving Spain's regulatory agenda on capacity markets, storage integration, and renewable curtailment reduction.

Revenue model

1. Regulated Transmission Revenue: As Spain's designated TSO, Red Eléctrica operates under a regulated tariff framework set by regulators (CNMC). Revenue comes from transmission network usage charges paid by grid users (generators, distributors, commercializers). Tariffs are regulated and reviewed periodically.
2. System Operation Services: Revenue from operating the Spanish electricity system, including balancing services, ancillary services, and grid management. Includes services like SRAD (Active Demand Response Service) with marginal pricing of €42.62/MW/hour.
3. Capacity Market Administration: Administers Spain's €9 billion capacity market scheme (€900M annually over 10 years from May 2026), compensating capacity providers selected through competitive bidding to ensure adequate generation/storage/flexibility during scarcity.
4. Grid Development and Planning Services: Revenue from developing and maintaining transmission grid infrastructure under national and European planning frameworks, funded through regulated network charges.
