LONDON, June 18 (Reuters) - British online supermarket

and technology firm Ocado ( OCDGF ) has expanded its partnership

with Spanish supermarket group Bon Preu with plans to build a

robotic warehouse near Barcelona, it said on Wednesday.

Ocado ( OCDGF ) runs an online supermarket in Britain through a joint

venture with Marks & Spencer ( MAKSF ), though its value is driven

by the sale of its cutting-edge warehouse technology to

retailers around the world.

Its shares are down 30% over the last year reflecting market

anxiety at the pace of new site openings for its existing

grocery retail partners and a lack of further technology deals.

Bon Preu was Ocado's ( OCDGF ) first international partner, signing a

deal in 2017 which enabled it to use Ocado's ( OCDGF ) technology to

fulfil online grocery orders from its stores.

The new automated warehouse, or Customer Fulfilment Centre

as Ocado ( OCDGF ) calls them, at Parets del Vallès in Catalonia, will

enable Bon Preu to offer a broader range of products with

greater freshness and higher availability.

"Our partnership with Bon Preu is an amazing example of a

retailer using the full strategic toolkit that Ocado ( OCDGF ) offers,"

Gregor Ulitzka, Europe President for Ocado Solutions, said.
