NRG joins Brightsource on solar project
The majority of solar power projects developed to date have been photovoltaic systems, in which sunlight is turned into electricity using semiconductor materials in panels, but several large-scale solar thermal, or concentrated solar, projects are in development.
Thermal solar power stations like the Brightsource project use mirrors to concentrate sunlight on a fixed point to heat a liquid that produces steam to power a turbine.
NRG, which previously announced a partnership to develop thermal solar plants with eSolar, said construction on the 392-megawatt Ivanpah project in the Mojave Desert had begun and was expected to be in operation by mid-2013.
Ivanpah has received a $1.375 billion conditional commitment from the U.S. Department of Energy for a loan guarantee, and has obtained all permits and approvals from both federal and California state agencies.

US Grid Gets an Overhaul for Renewables
WASHINGTON - The US took a significant step towards a cleaner energy future on May 13th, 2024. The Federal Energy Regulatory Commission (FERC) approved the first major update to the country's electric transmission policy in over a decade. This overhaul aims to streamline the process of building new power lines, specifically those that connect different regions. This improved connectivity is crucial for integrating more renewable energy sources like wind and solar into the national grid.
The current system faces challenges in handling the influx of renewables. Renewable energy sources are variable by nature – the sun doesn't always shine, and…
