Sylvan and GridLab_Renewables Transmission Rights
The practice of requiring long-term firm point-to-point transmission rights for new generators in the Pacific Northwest traditionally supported reliability for utilities that rely on BPA transmission, but has not adapted well to an environment with increasing penetrations of renewable resources....
Grid-Forming Battery Energy Storage Systems; Brief for Decisionmakers
Grid-Forming (GFM) Inverters GFM have received a lot of attention recently in power system organizations including NERC. The technology promises to address many of the stability issues facing the transmission system as the resource mix moves from spinning assets to...
Transmission Reliability Impacts of Retiring Conventional Generation
This report describes the transmission system reliability risks associated with the retirement of synchronous generators, such as coal and natural gas plants, and the shift towards inverter-based resources like solar PV and battery energy storage systems (BESS). It highlights the...
