Eroski opened an 864 m² supermarket in Erandio, Bizkaia, on 12 November 2026, creating 22 jobs. The Eroski Center is at 2 Calle Antonio Trueba and carries food from Basque suppliers.

The cooperative said staff received 2,637 hours of training before the opening. Eroski lists the supermarket as open from 09:00 to 21:00, Monday to Saturday. It already operates in Erandio: trade publication Indisa reported the opening of an Eroski City on Avenida Madaripe in 2021.

Local sourcing is central to the range. Across the Basque Country, Eroski says it works with around 367 local suppliers, buys €503 million of products from the region and sells about 7,991 regional lines. Those figures describe the wider network, so they do not tell suppliers how many local lines have been listed in Erandio.

The shop also has space for organic and specialist foods, including products for customers avoiding gluten or lactose. That gives regional producers routes onto shelves beyond the fresh categories that help distinguish Spain’s regional supermarket chains. For suppliers, the question is whether a product has a role in this store’s range or can support a listing across multiple branches.

Eroski fitted the store with enclosed refrigerated cabinets, LED lighting and updated refrigeration and climate control. It did not disclose measured energy use for the site.

The opening extends the cooperative’s local sourcing model, which sits alongside its Spanish own-label ranges. Eroski had 352 food stores and petrol stations in the Basque Country at the end of 2025. The opening statement does not give an updated regional store count.

The next thing to watch is whether the regional lines featured at launch gain permanent space. That will give suppliers a clearer signal about repeat orders than the opening assortment alone.

Editor’s note: Store details come from Eroski’s 12 November announcement and its Erandio store listing. Indisa reported the earlier Avenida Madaripe opening in October 2021. Regional sourcing figures are Eroski’s and do not describe purchases for the Erandio store alone.
