In its recent report on solar integration within the Hawaiian grid, the National Renewable Energy Laboratory finds that distributed and utility scale solar can be reliably accommodated by electrical grids on Maui and Oahu at penetration rates of 20%.
A recent NREL report finds that concentrating solar power systems (CSP) with thermal energy storage (TES) provide value to the grid that is $30/MWh to $51/MWh higher than conventional base load generation. The analysis focused on grid performance in California under a 33% renewable scenario.
This assessment was prepared by North American Electric Reliability Corporation in its capacity as the Electric Reliability Organization1 and provides an independent view of the 10‐year reliability outlook for the North American BPS,2 while identifying trends, emerging issues, and potential risks.
This report prepared by the Brattle Group and sponsored by SEIA demonstrates that adding solar PV could have significantly reduced energy prices for electric customers in Texas during the summer of 2011.
