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. .
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. .
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 been canceled. SEIA actively. T1 will build “G2 Austin,” a mass-producing solar cell factory with an estimated capital expenditure of up to $850 million. Once in production, the facility could produce up to 1,800 advanced manufacturing jobs, pending the negotiation of state and local incentives. [pdf]

The project, considered the world's largest solar-storage project, will install 3.5GW of solar photovoltaic capacity and a 4.5GWh battery storage system. The project has commenced in November 2024. [pdf]
Originally announced in November 2024, the NEA Kolda project is set to become West Africa’s largest solar-plus-storage complex. In April 2025, AXIAN awarded the engineering, procurement, and construction (EPC) contract to Voltalia and Entech Smart Energies. [pdf]
This ambitious project, spearheaded by the Barbados Electric Light & Power Company (BLPC), is a pivotal move towards the island’s transition to clean energy. By storing solar-generated power for use during peak evening hours, this initiative supports a more sustainable and reliable energy supply. [pdf]
To determine how long solar energy storage can last, it depends on various factors, including 1. battery type, 2. usage patterns, 3. capacity of the storage system, 4. environmental conditions. The longevity of solar energy storage is primarily influenced by the type of batteries being used. [pdf]

The Republic of Moldova will install a 75 MW energy storage system (BESS) and 22 MW internal combustion engines as part of a project funded by the U.S. Government through USAID. The Ministry of Energy has announced that a tender has been launched for this purpose. [pdf]
Project Summary: The project involves the development of a 36-megawatt (MW) solar power project and 40 megawatt hours (MWh) of battery energy storage solutions across various selected islands in the Maldives. [pdf]
This Balkan nation is flipping the script with a 200MWh battery storage project that’s turning heads globally. Funded by a $234 million U.S. grant, it’s like giving their grid a giant power bank – one that could charge 27 million smartphones simultaneously [1] [2]. [pdf]
The project is expected to achieve an annual production capacity target of 5GWh by the end of 2025, and upon completion, it will become SynVista's core production base in Southeast Asia, providing important support for regional clean energy development. [pdf]
Polish state-owned energy company PGE Group announced a tender for the construction of a battery energy storage facility in Żarnowiec, which is likely to become the nation’s largest once completed. The facility will have a power output of 263 MW and storage capacity of at least 900 MWh. [pdf]
