Is there a need for pumped Energy Storage in Spain?

In Spain, the country’s massive deployment of solar and wind power has run in tandem with building about 5,500 MW of pumped energy storage for a grid with a peak power consumption similar to California (about 43,000 MW).49Even with such a high investment in pumped storage there will be a need for more in the future.

What is the value of pumped Energy Storage?

Many expert studies have been performed that demonstrate the value of pumped energy storage, including CAISO’s Bulk Energy Storage Case Study, which found that a 500 megawatts (MW) pumped energy storage project in Southern California would provide ratepayers with a savings of up to $51M per year from improved efficiencies in system operation.

How much would it cost to upgrade a pumped storage facility?

The extra upgrades at year 50 we estimate, based on industry experience and projected with civil works inflation, at about $90 per MWh in 2026 dollars, or about one-fifth the cost of building a new pumped storage facility. For the full assumptions see table A3 in the Appendix.
