It is entirely PR fluff.

 Iberdrola is making progress in the construction of new energy storage systems with batteries.
      The electricity company is already building five facilities with almost 150 MW
  The company is also making progress in pumping in the Cáceres area.

  Iberdrola is promoting new energy storage projects with batteries. The company, which already has a solid presence in the renewable energy sector, is developing a series of key facilities that will enable it to optimise the use of energy generated by renewable sources such as solar and wind.
 Among the most important projects are the six battery energy storage systems (BESS) that the utility has begun to build in several autonomous communities. These facilities, which have a combined capacity of 150 MW, are backed by aid from the Strategic Programme for the Recovery and Transformation of the Economy, and will generate 100 direct and indirect jobs. The storage capacity of each of these plants is two hours, which will provide flexibility to the electricity system, allowing for the storage of surplus energy when renewable production is high to be released later at times of higher demand.

They are mere toys. A realistic size for grid stabilisation is 100MW per facility and multiple units near to renewable producers and major cities. Buffer at source and buffer near the biggest loads so that the network infrastructure can be used more efficiently 24/7.
The three planned grid connected ones near me intended for true load shifting are each 1GW power and 4GWh capacity. UK's largest BESS are typically now 100MW/200MWh there is a big cluster of existing kit around 49.99MW due to historical planning rules about national infrastructure.

Iberdrola pioneered the installation of batteries alongside renewable energy sources. With a 3MW battery and 9MWh of storage capacity, Campo Arañuelo III, in Cáceres, was the first photovoltaic project in Spain to incorporate a storage battery.
 ...
 Iberdrola also remains committed to large-scale pumped storage hydroelectricity. In this field, the company has a significant presence in projects such as Cortes-La Muela, in Valencia, and Tamega, in Portugal, with the La Muela plant being the largest pumped storage facility in Europe, with an installed capacity of 1,293 MW.

The pumped storage facility if used correctly should have been able to pull their nuts out of the fire when the shit hit the fan.
Their claim to be the largest pumped storage in Europe is also questionable as Dinorwig near Snowdonia in Wales is rated at nominal 1.8GW (actual 1728MW peak) and 9.1GWh capacity.

1.8GW with 12s response to full power. Very impressive engineering feat.

Dinorwig ranks at #14 in world's largest pumped storage and La Muela at #22. It is only the largest on mainland Europe.
