Sverige

• In Tomteboda, Stockholm's largest PV roof-mounted plant, produces 400 MWh per year (1465 PV panels covering an area of 4000 m²). Co-owned by Areim and Blackstone and operated by Obligo Real Estate. (2021)
• The largest solar power plant in Sweden is built by a home-owner's co-op (HSB Södermanland) in cooperation with the energy company Energiengagemang. 41600 PV panels with a total power of 14 MW.
• In Morgongåva (40 km west of Uppsala) the logistics center of online pharmacy Apotea features Sweden's largest roof-mounted PV array with a capacity of 2.3 MW, enough to supply the building's entire annual electricity demand. Built by Solkompaniet. SVT.
• The ports of Stockholm and the port of Södertälje together have almost 4 GW of solar PV panels, and have plans for more.

Misr

• Benban solar park in southern Egypt is one of the world's largest PV plants, covers an area of 37 km² and has a power generation capacity of 1.65 GW (given the site's insolation expected to yield 3.8 TWh per year).
• In Kom Ombo, Egypt's largest privately-owned solar PV plant is expected to start commercial operation in January 2024. ACWA Power (Saudi Arabia) owns and operates the 200 MW utility-scale plant.

Europe

• Uniper (the recently nationalised German energy company) plans two PV plants near existing industrial sites in Wilhelmshaven (300 MW + 17 MW).
• Belgium's first floating PV plant. On a man-made lake on a site owned by Sibelco, a raw material producer.
• Spanish energy company Iberdrola commissioned a 500 MW solar PV park at Núñez de Balboa in the western Spanish region of Extremadura. At the time Europe's largest PV plant, as seen by NASA's Earth Observatory. The project cost €300 million and is made of 1.43 million PV panels. Via @S_Johan_Lindahl.

Asia

• Oman seems to be on a roll. Their governmental energy company Hydrom (recently created to spearhead their green energy transition) is planning a massive green hydrogen project with a capacity to produce 750 kiloton/year (if I understand correctly). 1, 2.
• In Qinghai province, China, a 2.2 GW solar PV plant was connected to the grid in 2020 (at the time the world's largest solar plant).

Americas

• In the five first months of 2023 the United States power sector saw more electricity generation from wind and solar (combined) than from coal for the first time ever. Many other countries have already passed this particular milestone (or phased out coal entirely), so welcome to the club, yankees, and keep it up.

Oceania

• In southern Australia, a 4 MW concentrating PV plant combined with 50 MWh thermal storage for almost round-the-clock power generation is now in operation. The Carwarp power plant is run by RayGen. The site uses triple-junction GaAs solar modules with almost 38% efficiency paired with water-based thermal energy storage. Each tower (there is four of them) has just over 4 m² of photoactive area producing 1 MW of electricity and 2 MW of heat (ΔT=90℃).
• 10 GW of solar power in Australia for Singapore.
• The largest PV plant in New Zealand sits atop a wastewater pond.
• The Nauru Solar Power Development Project - Battery Energy Storage System is a 6 MW solar plant and a 2.5 MWh battery storage system that will increase the share of renewable electricity in Nauru from 3% to 47% (like many other Pacific islands, Nauru relies almost entirely on diesel generators for power), which is expected to fully cover the island nation's current daytime electricity needs.
