Hydrostor Launches 4 GWh Compressed Air Energy Storage Project in Ontario
Canadian developer Hydrostor has announced the Quinte Energy Storage Centre, using advanced compressed air energy storage (A-CAES) technology. Phase 1 at 500 MW/4 GWh can power 500,000 homes for 8 hours and is expected online in the early 2030s, with future expansion to 2 GW/16 GWh. The project has a 50-year design life and has secured a C$50 million development loan from the Canada Growth Fund, with an estimated GDP contribution exceeding C$1.4 billion.
Texas Solar Generation to Surpass Coal This Year
EIA's Short-Term Energy Outlook projects that Texas ERCOT grid solar generation will reach 78,000 GWh in 2026, surpassing coal at 60,000 GWh. Solar is expected to rise to 12% of Texas's generation mix while coal falls to 13%. Texas accounts for 40% of new U.S. solar capacity, with developers planning 14 GW of additions. The 837 MW Tehuacana Creek 1 solar-plus-storage facility is the largest single PV installation in the U.S. this year.
Japan Awards 1.25 GW of Battery Storage in Capacity Auction
Japan's third long-term decarbonization capacity auction awarded 1.25 GW of battery storage projects. With the introduction of minimum duration requirements for the first time, BESS bid prices dropped significantly while awarded capacity remained robust. Japan is accelerating storage deployment to support renewable energy integration. The results indicate that declining storage costs, combined with maturing market mechanisms, are laying the groundwork for larger-scale storage procurements in future auction rounds.
Brazil Deploys 4.4 GW of Solar in Q1, on Track for 13 GW in 2026
Brazil added 4.4 GW of solar capacity in Q1 2026, comprising 2,295 MW of utility-scale and 2,177 MW of distributed generation across over 245,000 new systems. At this pace, annual additions could reach 13.4 GW, exceeding earlier forecasts of 10 GW. The Brazilian solar association notes that free-market contracts are driving utility growth, while grid connection bottlenecks and regulatory changes remain key challenges for the sector.
Datang Plans 14.6 GW Renewables Cluster in Inner Mongolia
Datang International, in partnership with Jiangsu Guoxin and Ordos New Energy, is building a massive wind-solar-coal-storage integrated base in Inner Mongolia with a total investment of RMB 58.1 billion. The project includes 8 GW of solar, 4 GW of wind, 2.64 GW of coal power and 2.04 GW/8.16 GWh of storage. Power will be transmitted 1,886 km via an 800 kV UHVDC line to Jiangsu, delivering over 40 TWh annually with clean energy accounting for more than 60%.
Global Solar Approaches 3 TW as Industry Focus Shifts to Integration
The IEA-PVPS annual market snapshot reports that global cumulative solar PV capacity reached approximately 2,974 GW by end-2025, with 698 GW added in the year. However, annual growth slowed to 16%, down sharply from 93% in 2023. China added 415 GW, accounting for 60% of global additions, while 39 countries added over 1 GW each. Module prices have fallen over 60% since early 2023, with Chinese manufacturers accumulating nearly US$5 billion in cumulative losses.
Grid-Forming Inverter Technology Takes Center Stage for Grid Resilience
As renewables displace conventional thermal power, grids are losing rotational inertia essential for frequency stability. Grid-forming inverters address this by creating a virtual synchronous machine that provides synthetic inertia and short-circuit capacity. In Scotland, Zenobe's Blackhillock BESS (200 MW/400 MWh) became the world's first battery project connected to a transmission system delivering full grid-forming services. Australia's ARENA has launched a US$100 million program to fund large-scale demonstration projects.
Genex Downsizes Bulli Creek Solar, Adds 1.7 GWh Storage
Genex has restructured Phase 1 of its 2.5 GW Bulli Creek multi-stage development in Australia, reducing the solar component from 775 MW to 300 MW while adding a 425 MW/1,700 MWh battery energy storage system. This rebalancing reflects the industry's active optimization of solar-to-storage ratios. With declining storage costs and growing grid demand for flexibility, co-located solar-plus-storage configurations are becoming the mainstream approach for large-scale renewable projects in Australia.
Offshore Floating PV Could Theoretically Meet Italy's Entire Electricity Demand
Italian researchers have identified the country's most suitable zones for offshore floating PV (FPV) deployment using a multi-criteria geospatial assessment model. The study found that developing just 2% of Italy's technically feasible offshore solar area could theoretically satisfy the nation's annual electricity demand. Offshore FPV avoids land-use conflicts of ground-mounted solar and benefits from proximity to coastal load centers, though the technology remains in validation and demonstration phases.
High Solar Penetration Reverses PPA Price-Suppression Effect in Spain
A peer-reviewed study of the Spanish electricity market reveals a counterintuitive finding: at high penetration levels, physical bilateral contracts (PBCs) from wind and solar actually raise wholesale electricity prices, reversing their price-suppression effect in earlier stages. The research suggests that once renewable penetration exceeds a certain threshold, the pricing mechanism and market behavior of bilateral contracts fundamentally change, carrying important policy implications for renewable market design globally.
German Storage Industry Returns to Growth
According to BVES market analysis, after a significant downturn in 2024, German storage companies' revenues rebounded strongly in 2025 and are expected to rise further in 2026. The association notes robust demand across residential, commercial and grid-scale segments, though uncertainties persist in policy direction, supply chain dynamics and intensifying competition. German transmission system operators began procuring inertia services from January 2026, creating a new revenue stream for storage assets.
French Nuclear Plants Adapt to European Solar Variability
Ricardo PLC analysis shows that since 2019, the midday-to-evening generation gap at French nuclear plants during summer has grown nearly eight-fold, as nuclear power actively adapts to the intraday variability of European solar generation. France's shift from baseload to more flexible peaking operation reflects the profound transformation of conventional power sources in a high-renewables context. As the world's highest nuclear-dependent country, France's experience offers valuable lessons for the global energy transition.
