US wants Greece as partner for pumped storage projects

Recognizing the importance of pumped storage hydropower technology as a means for energy storage, the US is promoting the establishment of a related international forum to bring together countries and companies for co-development of such projects.

According to sources, Greek deputy energy minister Gerassimos Thomas has received an invitation from the US department of energy and the International Hydropower Association requesting Greece’s participation in a US-headed multidisciplinary platform that will seek to reinforce the role of pumped-storage technology in current and future energy systems.

Pumped storage hydropower supply during the pandemic has provided vital energy support for US households, hospitals and schools, American experts have determined.

Washington believes pumped storage hydropower projects are capable of enhancing the reliability of grids and supporting further renewable energy penetration. This technology, regarded as tried and tested, can be further developed in the energy transition era, US experts support.

Pumped storage hydropower currently represents about 94 percent of global energy storage capacity, latest data has shown.

A pumped storage hydropower project planned by Greece’s GEK TERNA in Amfilohia, western Greece, is regarded as a pioneering initiative in Europe.

The country’s energy ministry has approached the European Commission for special funding support for this project, budgeted at over 500 million euros.

 

Pumped-storage project support plan delivered to Brussels

The energy ministry has delivered to the European Commission, for approval, a special support framework proposal concerning a 680-MW pumped-storage hydroelectricity project planned by GEK TERNA in Amfilohia, western Greece.

The project has been on the EU’s list of Projects of Common Interest (PCI) since 2012, while its studies have received Juncker Plan financing.

The total budget of the project, planned to generate 816 GWh annually, is expected to exceed 500 million euros.

Pumped-storage hydroelectricity allows energy from intermittent sources, such as solar, wind and other renewables, or excess electricity from continuous base-load sources, including coal, to be saved for periods of higher demand.

Also, pumped-storage hydroelectricity is a technology that promises major  support for domestic value-added sectors as its investments concurrently create thousands of jobs, boost public revenue, tax collections and social security fund contributions, besides resolving energy issues.

PPC eyeing Dubai pumped storage hydropower project

The main power utility PPC is preparing to submit an offer for the construction of a 250-MW pumped storage hydropower plant (PSHPP) in Hatta, southeast of Dubai City.

The project, estimated to be worth over 450 million euros, is planned to utilize water at the Al Hattawi dam in Hatta, near the UAE’s border with Oman.

PPC aims to take part in the project’s tender as the head of a consortium including Archirodon Construction (Overseas) Co Ltd. and Hitachi – Mitsubishi Hydro Corporation.

The project description includes construction of a higher-elevation reservoir with a storage capacity of 880 million gallons, 300 meters above the Al Hattawi dam, whose storage capacity measures 1.72 billion gallons of water. The dam lies 400 meters above sea level. The distance between the existing dam and prospective higher-elevation reservoir will be approximately 3 to 4 kilometers.

During off-peak hours, turbines are planned to pump water from the existing dam to the higher-elevation reservoir, utilizing solar energy.

Last June, DEWA, the state-run Dubai Electricity and Water Authority commissioned EDF, at a price of 15.8 million dollars, to prepare plans for the project, including design, geological, hydrygeological, environmental and excavation studies.  DEWA announced the completion of this stage in November.

An initial November 18, 2018 deadline has been extended to January 13 following requests by participants.

PPC and Archirodon, a Dutch group headquartered in Dordrecht, are joining forces for the first time following the signing of a MoU for a five-year partnership, announced last October.

Archirodon has maintained an international presence, offering EPC services, for approximately 60 years, including in the Middle East and North Africa regions.

 

PPC, Terna in pumped-storage hydroelectricity project talks

The main power utility PPC is engaged in talks with Terna Energy for a possible partnership concerning the latter’s plan to develop pumped-storage hydroelectricity facilities in Amfilohia, western Greece, and the Cretan region Amari, PPC’s chief executive Manolis Panagiotakis disclosed at the Thessaloniki International Trade Fair while addressing the utility’s decision to make a decisive turn towards green energy.

The energy sector’s future lies in renewable energy incorporating storage systems, Panagiotakis supported.

“Crete and other areas have potential. We have begun talks with Terna and other firms for the development of such projects by also utilizing existing lakes, such as the artificial lake at the Amari area’s rivers, with wind turbines,” the PPC boss explained.

Pumped-storage hydroelectricity allows energy from intermittent sources, such as solar, wind and other renewables, or excess electricity from continuous base-load sources, including coal, to be saved for periods of higher demand.

Terna Energy plans to develop a 680-MW facility in Amfilohia and a 93-MW plant at Amari, Crete.
