Norvento submits a 60 MWh battery in Abadín for public consultation

The Territorial Department of Lugo of the Ministry of Economy and Industry of the Xunta de Galicia submits for public information the request for the granting of the prior administrative and construction authorizations for an electrical energy storage installation using batteries called Bess Farrapa II-Hybridization of Farrapa II wind farm and its evacuation infrastructure, promoted by Norvento, S.L., in the municipality of Abadín. The agreement, signed on November 2, 2026, by the territorial director, Gustavo Casasola de Cabo, is published in the Official Gazette of Galicia (DOG) no. 214 of November 9, 2026, in section VI of announcements, under the official reference zadicv55-xay2-v5b6-u6s0-aaahvl9rw6u2. The processing corresponds to file PB 11/2024.

The announcement is part of the processing line for electrical energy generation and storage installations in Galicia, as the hybridization of wind farms with battery systems has consolidated as a formula to improve the management of produced energy. The procedure is applied in accordance with Law 24/2013, of December 26, of the electricity sector; Royal Decree 1955/2000, of December 1, which regulates the authorization procedures for electrical energy installations; Law 9/2021, of February 25, on administrative simplification and support for the economic reactivation of Galicia; and the Resolution of February 19, 2014, by which the administrative authorization procedure for construction is approved. To this are added Law 39/2015 and Law 40/2015, of October 1, on common administrative procedure and the legal regime of the public sector.

Sixty megawatt hours linked to the Farrapa II wind farm

According to the technical characteristics collected in the project, the installation will have:

• Generation access capacity: 14.4 MW.
• Storage power per converter: 7.2 MW.
• Storage capacity: 60 MWh.
• Battery technology: lithium iron phosphate (LFP).

The system is integrated into the SET substation of the Farrapa II wind farm, so that the storage and wind generation share the connection point. The installation will be presented as a hybridization of the existing park, not as an independent plant.

Twelve containers, two converters and an underground 30 kV network

The project details an installation composed of the following elements:

• Twelve LFP lithium-ion battery containers, with a 12P416S configuration (twelve racks in parallel with 416 cells in series each), with a useful energy per container of 5.016 MWh, limited to 5 MW.
• Two power electronic converters model Norvento nXL PCS 7200 (or similar), with a unit nominal power of 7.171 MVA at 40 ºC and 1500 Vdc, and an output voltage of 690 Vac per converter.
• Two step-up transformers from 690 V to 30 kV, connected to the medium voltage busbar of the substation via a collector network and line input cell.
• Underground medium voltage line of 30 kV between the SET substation of the Farrapa II wind farm and the storage system.
• New medium voltage cell busbar at the substation, which will integrate the wind farm’s generation circuit and the new storage system.
• Sectioning center that unifies the two storage circuits coming from the converters, with a protection cell for the auxiliary services transformer and an output line cell to the substation.

Added to this set are control, communication, and monitoring systems (PMS, Scada), grounding, fire protection in each container through automatic detection and extinction with condensed aerosols, and liquid cooling per container. The civil works include a platform in the vicinity of the substation that will support the fourteen twenty-foot containers —twelve for batteries and two for conversion—, as well as the cages for the cable conduits.

Thirty days to consult and object

The documentation remains available to interested parties at:

• The Energy Section of the Territorial Department of the Ministry of Economy and Industry of Lugo, at Rolda da Muralla, 2nd floor, 27071 Lugo, Monday to Friday between 9:00 and 14:00 hours.
• The notice board of the Abadín City Council.
• The Transparency and Open Government Portal of the ministry, at the address https://economia.xunta.gal/transparencia/instalacions-de-xeracion/abadin.

The period for submitting objections or observations is thirty (30) days counted from the day following the publication of the agreement in the DOG.

The public information process opens the door for neighbors, mountain communities, and environmental groups of Abadín to present technical or territorial objections before the Xunta resolves on the authorization. The result conditions a relevant piece of the energy map of the Mariña lucense region: sixty megawatt hours of storage that would allow managing the surpluses of the Farrapa II wind farm instead of dumping them into the grid.
