Two builders are set to duke it out over a 24-mile stretch of water that’s key to Spain turning into Europe’s main pumped hydro market.

The builders, Ingenieria Pontificia and Romero Polo Group, have put ahead plans for pumped hydro services at reverse ends of the identical reservoir. And Romero Polo has claimed the Riba-roja reservoir on the Ebro River simply isn’t sufficiently big for each tasks. 

The crops, Mont-Negre within the province of Zaragoza and Gironés & Raïmats in Tarragona, have each been registered as European Union tasks of frequent curiosity. That places them on the identical footing as interconnection applications by way of eligibility for EU funding. 

However they “are clearly incompatible between them each for hydraulic, electrical and environmental causes,” stated Gironés & Raïmats developer Romero Polo in documentation hosted by the European Community for Transmission System Operators — Electrical energy (ENTSO-E), an business physique.

“The quantity of the Riba-roja reservoir doesn’t enable the joint operation of two large-capacity hydro-pumping stations and their compatibility with current makes use of,” Romero Polo stated. “The water authority has thought-about that each tasks are in competitors and, due to this fact, are incompatible.”

Moreover, stated the developer, the Riba-roja is a part of the Natura 2000 European community of core breeding and resting websites for uncommon and threatened species. 

“European laws point out that within the case of other tasks solely that challenge that minimizes impacts on Natura 2000 websites needs to be licensed,” Romero Polo famous.

Neither developer responded to requests for data from GTM. 

Nor did the Spanish Ministry for Ecological Transition and Demographic Problem, though the Ministry’s 2021-2030 Nationwide Power and Local weather Plan (Plan Nacional Integrado de Energía y Clima, or PNIEC) hints that solely one of many tasks is anticipated to go forward.

Pumped hydro in Europe 

The three.Three-gigawatt Mont-Negre and the three.1 GW Gironés & Raïmats crops are each virtually equal to the additional Three.5 GW of pumped hydro capability that Spain expects to put in over the approaching decade.

A 3rd challenge, Navaleo in Leon, would provide 552 megawatts of capability and permit Spain to realize its PNIEC goal. Navaleo has additionally been registered as a challenge of frequent curiosity. 

The brand new capability would put Spain forward of Austria and Europe’s present pumped hydro chief, Italy, based on ENTSO-E information in a quarterly report on electrical energy markets issued by the European Fee final yr.  

The report confirmed Spain, at the moment fourth behind Italy, Germany and Austria, has extra operational, deliberate and introduced pumped hydro capability than every other nation in Europe. 

It’s unclear if the incompatibility between the Mont-Negre and Gironés & Raïmats tasks might finally result in Spain lagging behind Germany, which at present has Europe’s second-largest pumped hydro capability figures and has additionally introduced important will increase. 

It’s also unsure precisely how Spain intends to obtain the additional capability provided that buyers will doubtless want a minimal 40-year offtake contract to make the capex-heavy tasks pan out, based on Rory McCarthy, senior analysis supervisor for European energy at Wooden Mackenzie. 

“Something lower than that, it’s going to lose” in a conventional public sale setting, he instructed GTM in an interview. “It’s not going to win in opposition to batteries, even at this stage.”

Primarily based on this evaluation, it appears the Spanish authorities must tailor an public sale particularly to pumped hydro if it desires to draw personal funding for the tasks. 

Power storage wanted for shift to renewable power 

Axel Narváez Kirkpatrick, managing director of Spain at Augusta & Co, a specialist monetary advisory and funding home, instructed GTM in an interview that new pumped hydro can be wanted to exchange technology capability misplaced by means of the phaseout of outdated Spanish nuclear crops. 

“By 2030 we’d solely have Three GW [of nuclear],” he stated. “Immediately now we have 7.four GW of put in capability. Pumped hydro goes to ease the closing of the nuclear crops.”

He added that new pumped hydro reserves might assist Spain cater extra cost-effectively for peak energy calls for which might be at the moment being met by means of costly thermal crops. It is a subject that has created headlines in current days as utility payments have soared in freezing climate. 

Spain’s plans for pumped hydro come as regulators more and more search for long-duration power storage choices to realize totally decarbonized electrical energy provides. 

This month, for instance, the Hawaiian island of Kauai unveiled plans for a solar-charged pumped hydro plant that might assist obtain an 80 p.c clear power electrical energy combine by the mid-2020s.

To achieve Europe’s formidable carbon discount objectives, “we’ll want better funding in hydropower tasks in Spain and all throughout the continent,” stated Will Henley, head of communications on the Worldwide Hydropower Affiliation, in an e mail. 

“As a clean-water battery, pumped storage hydropower specifically offers a number of advantages by means of its flexibility and storage, complementing and supercharging variable photo voltaic and wind energy.”
