California batteries sustain near 24-hour solar run
On Feb. 1, California’s batteries bridged the solar gap with seamless precision. After discharging through the night until sunrise, they spent the daylight hours charging, then pivoted back to exporting power well past midnight – effectively sustaining the state on solar energy for a full 24-hour cycle.
Pexapark records 12 European PPAs for 724 MW in January
Swiss analytics firm Pexapark finds January recorded roughly half the deal count and volume in new European power purchase agreements than the month prior.
An ever-changing market: Delving into the heart of power purchase agreements
Cross-border VPPAs expose corporates to Basis Risk, causing settlement price gaps and weakening confidence in these hedging tools, contributing to a 35% drop in European PPA signings in 2025 amid complex market conditions. The market is shifting toward more structured, domestic, and hybrid PPAs, supported by BESS and modern IPPs, to better manage risk and realign buyers, sellers, and lenders.
The impact of agrivoltaics on soil properties
New research shows how agrivoltaic systems can reshape soil by altering moisture, temperature, and microbial activity, creating heterogeneous zones under and between panels. Proper design and management can boost soil health and crop resilience, especially in degraded or arid regions, though long-term effects remain uncertain.
World’s largest solar-plus-storage project completes initial grid synchronization
The first phase of the MTerra solar project in the Philippines, set to be the world’s largest solar-plus-storage site once completed, has achieved initial synchronization and energization to the Luzon grid. Project developers are anticipating the project to being exporting power by the end of the month.
Guatemala PEG-5 tender draws 51 bidders for 4.7 GW of capacity
Guatemala’s Generation Expansion Plan 5 (PEG-5) tender has drawn 51 bids totaling nearly 4.7 GW – more than triple the 1.4 GW sought – with around 2 GW of solar projects, including hybrids with storage, competing for long-term supply contracts starting between 2030 and 2033.
What happens when type-C cracks strike photovoltaic modules
An international research team used high-resolution electroluminescence imaging to quantify type-C cracks in 100 PV modules after 11 years of operation, linking crack distribution to real-world power loss. Concentrated cracks within individual cells were found to cause disproportionately high losses, highlighting the importance of cell-level crack analysis for effective PV maintenance.
Chinese Academy of Sciences unveils 101 MW compressor for compressed air energy storage
The new compressor is described as the world’s most powerful single-unit compressed air energy storage (CAES) system, with a maximum discharge pressure of 10.1 MPa and an efficiency of 88.1%.
Slovenia adds 146.5 MW of solar in 2025
Slovenia installed less solar in 2025 than in 2024, largely down to a sharp drop in residential installations. The country’s cumulative solar capacity now stands at 1.57 GW.
The prospects for ultra-high-temperature heat pumps
An international research team has reviewed emerging solid-state and gas-cycle heat pumps capable of reaching temperatures of up to 1,600 K, assessing their challenges, applications, scalability, and technology readiness levels. The researchers say these systems could outperform conventional high-temperature heating technologies by achieving coefficients of performance above 1.
