Indian Railways could power one in four trains with its own solar panels
Feeding solar electricity directly from its own panels into overhead lines on a fully-electrified rail network would be more cost-effective for the state-owned company than buying that green power from the grid, according to a new study.
Looking at the world’s largest solar power stations
Solar energy pioneer and founder of Wiki-Solar, Philip Wolfe updates his series of blogs on the world’s largest solar power stations, first published in pv magazine in 2019. At that time, there were no single solar power plants over 1 GWAC. The record now is 2.2 GWAC.
Goa invites EoI to set up floating solar plants at four dam locations
Developers have until September 30 to lodge their interest to install grid-connected floating solar plants on the water reservoir surface at Salaulim, Amthanem, Anjunem, and Chapoli Dams in the Indian State of Goa.

Cheapest long-duration storage for systems with high renewables
National Renewable Energy Laboratory researchers have studied which tech offers the lowest levelized cost of energy to provide the US Western Interconnection grid with electricity when wind and solar are not available. They assumed 85% renewables penetration and determined that geologic hydrogen storage and natural gas combined-cycle plants with carbon capture storage are the cheapest options for 120-hour discharge applications.
