Sungrow proposes multi-microgrid clusters for mining above 100 MW
Sungrow has released a mining microgrid power solutions white paper in partnership with TÜV Rheinland and the China Electrotechnical Society covering application scenarios from 2.5 MW up to more than 100 MW.
The battery cost disconnect
For years, the battery energy storage (BESS) story has followed a familiar script: costs fall, deployment accelerates, economics improve. Even when cell costs rose and system prices briefly flattened during the 2021-22 lithium price spike, the narrative largely held. Paola Perez Peña, senior principal analyst at S&P Global Energy, examines why the latest jump in lithium prices has only had limited impacts on overall BESS costs so far.
Solar and storage expected to drive 86 GW capacity surge in the U.S. this year
New federal data shows solar and battery assets will comprise nearly 80% of all new utility-scale power additions planned for the U.S. electric grid this year.
China tightens carbon accountability framework, strengthening structural push for renewables
Beijing has introduced a stricter national carbon evaluation system that formally holds provincial governments accountable for emissions reduction and energy transition targets.
Cooling PV modules with hydrogel-coated paper
A Vietnamese research team has developed a low-cost passive cooling system for PV modules based on hydrogel-coated paper that combines water flow and interfacial evaporation to reduce operating temperatures. Outdoor tests showed temperature reductions of up to 14 C and efficiency gains of up to 16.8%, with stable operation achieved using both freshwater and natural seawater.
Ireland’s grid-scale solar breaches 1 GW generation mark
Grid-scale solar PV electricity generation surpassed 1 GW in mid-April, which marked a new record in Ireland according to the country’s high-voltage transmission system operator Eirgrid. Around 500,000 customers’ power needs can be met with 1 GW, Eirgrid estimates.
How to electrify greenhouses with semi-transparent PV, heat pumps
Researchers in Canada found that 69%-transparent crystalline silicon semitransparent PV modules can improve tomato greenhouse yields by up to 38% while maintaining healthy plant growth through beneficial partial shading. Their simulations also showed that combining rooftop agrivoltaics with heat pumps can fully eliminate fossil fuel heating.
CATL raises $5 billion in share sale, Sungrow files for Hong Kong IPO for the second time
CATL has completed a roughly $5 billion share sale in Hong Kong on Tuesday. Meanwhile, Chinese inverter and battery manufacturing giant Sungrow is making a second attempt at an IPO after its initial listing bid, launched in October 2025, lapsed.
Bangladesh launches 495 MW solar tender
BPDB has launched a tender for 495 MW of grid-tied solar power projects across 10 sites in Bangladesh, with capacities ranging from 25–100 MW and full private investment required. The bid structure, which places land acquisition and financing risks on developers, has drawn investor concerns over bankability and limited project attractiveness.
Cox buys Iberdrola Mexico for $4 billion
Cox has acquired Iberdrola México for $4 billion, adding 2,600 MW of capacity and becoming Mexico’s largest private power supplier with a 12 GW renewable project pipeline.
