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...
Practical Guidance and Considerations for Large Load Interconnections
This Practical Guidance and Considerations for Large Load Interconnections Interim Report is still undergoing review, but it provides critical information that can inform high impact decisions being made daily by utilities and regulators. For that reason, this working paper is being...
Surplus Interconnection Report
Surplus interconnection refers to the practice of allowing new electricity supply resources to connect to the grid using the same interconnection rights that have already been allocated to existing generators.7 As outlined in the Surplus Interconnection Technical Whitepaper, hundreds of...
Surplus Interconnection Service
The U.S. electric grid is facing a triple threat of rising rates, rapid demand growth, and increasing reliability risks. These issues have wide ranging impacts on the future of America’s economic growth, industrial competitiveness, and national defense. Meanwhile, there remain...
Surplus Interconnection Technical Report
The power grid has emerged as the primary bottleneck to meeting growing electricity demand with low-cost clean energy. Demand for electricity—and especially clean electricity—has soared, driven by electrification in various sectors, the rise of data centers for artificial intelligence (AI),...
Grid Reliability in the Clean Energy Transition
MANAGING GRID RELIABILITY IN A CHANGING WORLD Summers and winters are introducing new grid reliability risks in the form of extreme heat and cold, both exacerbated by the climate crisis.12 Heat waves cause people and businesses to crank their air...
Solar Production Fact Sheet
How much solar power capacity is available in the wholesale power market managed by the California Independent System Operator? According to the California Independent System Operator (CAISO) as of 11/07/2024 there were 19,853 megawatts (MW) of solar generation connected to...
Reliably Reaching California’s Clean Electricity Targets Deep Dive
As part of the “Reliably Reaching California’s Clean Electricity Targets” study, concurrent wind and solar resource data was used to project the generation at renewable energy sites throughout California and the broader WECC area. The concurrent data spanned the period...
