SEIA makes major solar project data available to the public through the map below. SEIA members have exclusive access to the list as a sortable, searchable MS Excel file that is updated monthly. This version contains additional, valuable information that is not included in the map below, such as the owner, electricity purchaser,. . SEIA does not guarantee that every identified project will be built. Like any other industry, market conditions may impact project economics and timelines. SEIA will remove a project if it is publicly announced that it has. [pdf]
There are more than 7,570 major solar projects currently in the database, representing over 290 GWdc of capacity. There are over 1,120 major energy storage projects currently in the database, representing more than 43,650 MWh of capacity. The list shows that there are more than 150 GWdc of major solar projects currently operating.
The Major Solar Projects List is a database of all ground-mounted solar projects, 1 MW and above, that are either operating, under construction or under development. The list is for informational purposes only, reflecting projects and completed milestones in the public domain.
There remains an enormous amount of capacity in the pipeline, with more than 139 GWdc of large-scale solar projects either under construction or under development. The Major Solar Projects List is a database of all ground-mounted solar projects, 1 MW and above, that are either operating, under construction or under development.
No matter how much generating capacity is installed, there will be times when wind and solar cannot meet all demand, and large-scale storage will be needed. Historical weather records indicate that it will be necessary to store large amounts of energy (some 1000 times that provided by pumped hydro) for many years.
Nature Reviews Electrical Engineering (2025) Cite this article Grid-scale, long-duration energy storage has been widely recognized as an important means to address the intermittency of wind and solar power.
There will also be a role for other, more efficient, types of storage. Nuclear power, and burning biomass (and perhaps some natural gas) and capturing the carbon-dioxide, may also play a role; however, these forms of generation are not well to suited to providing all of the flexibility that will be needed to complement wind and solar power.

A thermal energy battery is a physical structure used for the purpose of storing and releasing . Such a thermal battery (a.k.a. TBat) allows energy available at one time to be temporarily stored and then released at another time. The basic principles involved in a thermal battery occur at the atomic level of matter, with being added to or taken from either a solid mass or a liquid volume which causes the substance's to change. Some thermal bat. [pdf]

The developer said the pumped-hydro scheme was declared a project of common interest by the EU in 2013 and thus received support from the bloc's Connecting Europe. . With no finance details included in the press release, Terna also refused to comment on such matters when contacted by pv magazine. With bankability a prime. . The energy ministry also told pv magazine it is preparing to tender 700 MW of battery storagethis year. Speaking at an energy storage webinar organized last year. [pdf]
Investors may be wary ahead of publication of an energy storage regulatory framework in Greece this summer. With a total installed capacity of 680 MW (production) and 730 MW (pumping), Athens-headquartered Terna Energy says the Amphilochia pumped storage project will be Greece’s largest grid connected energy storage investment.
An increasing number of local and foreign companies are interested in building energy storage facilities in sun-loving Greece using battery technology. In fact, the Regulatory Authority for Energy (RAE) has been receiving applications for permits concerning battery storage plants.
pv magazine has determined Athens will devote €450 million of the €30.5 billion it expects to secure from the EU's post-Covid recovery and resilience facility, to energy storage. Of that €450 million, around €200 million will be channeled into battery facilities, via the planned 700 MW tender.
If built, the large scale facility can boost Greece’s independence from fossil fuels and the government’s strategy for a coal-free electricity system by 2025. Investors may be wary ahead of publication of an energy storage regulatory framework in Greece this summer.
Public Power Corp. (PPC) has also set its sight on storage and recently received a permit for a 100 MW project in Ptolemaida in Western Macedonia. Other companies include Magna Victoria, Melven, Mars BESS and MS Komotini, which have already received permits for a combined 400 MW of battery capacity in various large projects.
Developer Terna Energy claims the Amphilochia pumped hydroelectric energy storage project has entered the final stretch. If built, the large scale facility can boost Greece’s independence from fossil fuels and the government’s strategy for a coal-free electricity system by 2025.
