US Battery Storage Projects Face Years-Long Grid Connection Delays

Falling costs have spurred a surge in grid-scale battery storage proposals across the US, but aging grid infrastructure and equipment shortages are causing massive backlogs. Roughly 750 gigawatts of storage capacity are now waiting for interconnection approval, with median wait times rising from about 1.5 years in 2015 to 5 years in 2025.

Y Combinator-backed Meteoric to test drones that clear clouds over solar farms

Meteoric, a startup founded by two Cambridge engineers, is developing autonomous drone fleets designed to fly into low- and mid-altitude clouds above solar farms and physically alter water droplets to reduce cloud reflectivity. The company says this chemical-free approach could boost energy output from existing solar installations by 10-30%, costing an estimated $30-60 per hour to operate, far cheaper than traditional cloud-seeding aircraft.
