Beyond gigawatts: Why India’s clean energy future depends on storage intelligence
The battery creates flexibility. The intelligence behind it determines how much of that flexibility the grid can harness. The next clean energy benchmark for India, therefore, might not just be a new number of gigawatts. It might be the ability to get the maximum out of every gigawatt.

Isaias ends historic Atlantic hurricane lull after sunny southern summer
In a new weekly update for pv magazine, Solcast, a DNV company, reports that an unusually quiet Atlantic hurricane season brought 10–20% above-average solar irradiance to Mexico and the southern US in August–September, while prolonged dry weather increased solar panel soiling losses. Tropical Storm Isaias is set to end the sunny spell, bringing widespread cloud cover, reduced irradiance, and potential hurricane impacts along the US Gulf Coast.
