HeliaDES reorganizes nine solar subsidiaries under a single partner in Madrid

Nine companies declared single-shareholder in favor of HeliaDES

The Official Gazette of the Mercantile Registry (BORME) issue number 157, corresponding to Monday, August 17, 2026, records entries 380975 to 380983 in the First Section (Business owners, registered acts), relating to the province of Madrid. In all of them, HeliaDES Fotovoltaica SL is constituted as the sole shareholder of each of the entities of the Oneland Inversiones group, upon the single-shareholder status of each company being declared.

The nine affected subsidiaries are: Oneland Inversiones 2 SL, Oneland Inversiones 3 SL, Oneland Inversiones 4 SL, Oneland Inversiones 5 SL, Oneland Inversiones 6 SL, Oneland Inversiones 7 SL, Oneland Inversiones 8 SL, Oneland Inversiones 9 SL and Oneland Inversiones 11 SL. All entries were formalized on August 10, 2026 at the Central Mercantile Registry (Section 8, Madrid Sheet), as stated in document BORME-A-2026-157-28.

Identical resignations and appointments in the nine entities

In each of the nine companies, exactly the same corporate governance operation takes place. The resignation —or removal— of Gilarranz Martín Santiago as joint managing director is recorded, and simultaneously Rueda Jiménez Fernando is appointed in his place, also with the position of joint managing director.

This pattern is replicated without any variation in the nine entries (numbers 380975 to 380983 of the BORME), which points to a coordinated group restructuring operation, in which the parent company, HeliaDES Fotovoltaica SL, assumes sole control and unifies the management of all subsidiaries under the same person.

Transfer of registered office to Madrid

In addition to the declaration of single-shareholder status and the change of director, each of the nine entities requests and obtains the change of registered office. The new registered address of all subsidiaries is set at Calle Musgo 2, 1.º C, Madrid.

The coincidence of the address in the nine entries reinforces the conclusion that this is a centralized grouping, probably to manage the group’s portfolio of photovoltaic assets from a single operating headquarters.

Registry details of the affected companies

The individual registry sheets of the entities, all at the Mercantile Registry of Madrid, are as follows:

• Oneland Inversiones 2 SL — Sheet M 817372
• Oneland Inversiones 3 SL — Sheet M 815171
• Oneland Inversiones 4 SL — Sheet M 817435
• Oneland Inversiones 5 SL — Sheet M 816851
• Oneland Inversiones 6 SL — Sheet M 816098
• Oneland Inversiones 7 SL — Sheet M 817025
• Oneland Inversiones 8 SL — Sheet M 816318
• Oneland Inversiones 9 SL — Sheet M 817026
• Oneland Inversiones 11 SL — Sheet M 815918

All acts were registered with the date of August 10, 2026 in Section 8 of the Central Mercantile Registry.

Relevance to the photovoltaic sector

The operation published in the BORME highlights a growing trend in the Spanish renewable sector: the asset and administrative concentration of investment subsidiaries under a single parent company. The restructuring of HeliaDES Fotovoltaica SL over its nine Oneland vehicles could respond to a strategy of tax optimization, simplification of corporate management, or preparation for a larger transaction (merger, refinancing, or portfolio sale). For creditors, investors, and suppliers of the group, the publication in the BORME constitutes the formal notice that the management of all subsidiaries now falls on a single person —Rueda Jiménez Fernando— and that the registered office has changed.
