By Martin McConnell March 9, 2026 This week on Projects Weekly, RWE Americas has announced the commissioning of more than 2 GW of renewable energy since the tail end of 2025. In Texas, Origis Energy has closed on $545 million in financing for a trio of projects, and Habitat Energy has announced a move into the U.S. with a co-located solar and storage optimization project in ERCOT’s South Zone. Also in the Lone Star State, CoServ and Base Power have announced a 100-MW residential battery program in Denton County. And North of the American border, GrandBridge and PowerBank have agreed…

Choosing a solar installer in North Carolina is one of the biggest home improvement decisions you will make. Both 8MSolar and Southern Energy Management (SEM) are Raleigh-based companies with real track records in the NC solar market. If you are weighing your options between the two, this comparison is here to help you make an informed decision with no pressure and no spin. Both companies care about clean energy and their customers. But when it comes to the details that matter most to homeowners like installation quality, engineering oversight, warranties, equipment options, and post-installation support, there are differences worth understanding.…

The UK solar market remains busy, but for very different reasons than this time last year. Of notifications about grid connections were issued four months ago nowand final dates are finally given to developers, buildouts can finally take place, and developers can connect projects that were mechanically completed up to twelve months ago. More than 4GWp is currently being built in the country. Some developers have continued with ‘business as usual’ – a risk as the first dates for distribution projects have yet to emerge and there are a number of projects receiving notifications after 2030.

Swedish thin-film solar panel manufacturer Midsummer has secured its largest ever order for production equipment, for a complete solar cell factory. It follows an initial order in May 2025 for a 15 MW line for the production of thin-film copper, indium, gallium and selenide solar cells (CIGS). March 9, 2026 Patrick Jowett Midsummer DUO Image: Midsummer Swedish specialist in the field of thin-film solar panels Midsummer has secured a follow-up order for machines for a factory for the production of thin-film solar cells. The contract, worth SEK 236 million ($14.8 million), is the largest order in the company’s history. It…

The “Battery Atlas 2026” report shows consolidation in the European battery market. More than 2,000 GWh of cell production capacity was announced in 2023, but the realistic forecast for early 2026 is around 1,190 GWh, of which around 673 GWh will be led by Asian companies. March 9, 2026 Pilar Sanchez Molina Image: RWTH Aachen University By ESS news RWTH Aachen University has published the third edition of the “Battery Atlas 2026”, produced by the Production Engineering of E-Mobility Components (PEM) chair. The free online report maps the European value chain of lithium-ion batteries. Titled ‘Mapping the European Lithium-Ion Battery…

The new product line includes 124–644 kW for heating and 128–632 kW for cooling, operates down to -15 C and supports various configurations with R454B or R410a refrigerants. March 9, 2026 Lior Kahana Italian heating and cooling specialist Thermocold has unveiled a new range of air-to-water heat pumps with axial fans and scroll compressors. The new system, called AWA HP SEA/XEA, is available in different versions and capacities. “High energy efficiency is ensured by extra-large heat exchangers and fans with high energy performance,” the company said in a statement. “Thanks to the innovative profile, the EC fans ensure high efficiency…

Importantly, the Energy Transition Expo held last week in Rimini, Italy, recorded a 10% increase in total visitors and a 9% increase in foreign visitors, according to organizers. “With 160 high-quality and rigorously scientific conferences, Key 2026 confirmed its status as one of Europe’s most important energy events, standing out for the comprehensiveness of the exhibition and content,” said the event’s organizer, Italian Exhibition Group (IEG). According to the organization, 530 buyers and delegations from 59 countries attended the conference, spread over 125,000 m² of exhibition space and 24 halls. The 2026 edition featured 1,065 exhibiting brands, approximately 30% of…

Global demand for lithium could exceed 13 million tons by 2050 under an accelerated energy transition, which is projected to be more than double the base case. Wood Mackenzies latest energy transition prospects for lithium. Without significant new investments, supply shortages could emerge as early as 2028. Even under Wood Mackenzie’s baseline scenario, existing supply projects are unlikely to meet demand beyond the mid-2030s, underscoring the need for sustainable investment across the value chain. “The lithium market is heading towards a supply shortage much faster than many industry players expect,” said Allan Pedersen, research director at Wood Mackenzie. “Under ambitious…

Researchers at TU Berlin say early demand for 24-hour carbon-free electricity could help bring advanced energy technologies to market faster through technology learning effects. The grant for the research was provided by Google, which has since announced plans to build the world’s largest iron-air battery. March 9, 2026 Matthew Lynas Early adoption of 24/7 carbon-free energy purchasing could quickly reduce the costs of new energy generation and storage technologies, potentially accelerating deployment and making 24-hour clean energy commercially viable, according to researchers from TU Berlin and Princeton University. The research suggests that a virtuous circle of innovation can be activated…
