ITER's self-consumption photovoltaic system authorized in Granadilla

The General Directorate of Energy of the Ministry of Ecological Transition and Energy of the Government of the Canary Islands has granted the entity Instituto Tecnológico y de Energías Renovables, S.A. (ITER) the administrative authorization for the “Self-consumption photovoltaic installation of 977 kW and storage of 2.15 MWh”, located in the municipality of Granadilla de Abona, on the island of Tenerife. The decision is formalized through Resolution No. 1388, dated September 2, 2026, and is made public through an announcement published in the Official Gazette of the Canary Islands number 184, dated September 14, 2026.

Legal framework and issuing body

The authorization is granted within the framework of the processing of file ER250051, managed by the General Directorate of Energy. The announcement is published in compliance with the provisions of Article 21 of the Law of December 16, 1954, on compulsory expropriation, which requires the publication of this type of administrative resolutions.

The full content of the resolution is available on the official page of the General Directorate of Energy, which can be accessed via the link provided in the gazette itself.

Characteristics of the installation

The authorized installation combines photovoltaic generation and energy storage, oriented towards self-consumption:

• Photovoltaic capacity of 977 kW.
• Storage system of 2.15 MWh.
• Location in the municipality of Granadilla de Abona, Tenerife.
• Ownership by Instituto Tecnológico y de Energías Renovables, S.A. (ITER).

Signature and delegation

The resolution is signed in Las Palmas de Gran Canaria on September 2, 2026. The document is signed, by delegation of signature (Resolution No. 462/2026, of March 20, 2026), by the Head of the Technical Energy Area, Alberto Miguel Blasco Lorenzo.

Relevance for the insular energy transition

The authorization promotes renewable self-consumption in the south of Tenerife, a further step in the decarbonization strategy of the archipelago. By combining photovoltaic generation with storage, the ITER installation contributes to strengthening insular energy autonomy and reducing dependence on fossil sources, in line with the energy transition objectives of the Canary Islands.
