Eastern Interconnection RA Study – ESIG Webinar slides
These slides were presented by Derek Stenclik and Sam Hostetter of Telos Energy at a webinar hosted by the Energy Systems Integration Group on July 1 2025. The material is based on a study in which resource adequacy across the...
Eastern Interconnection RA Study – Slidedeck
This slidedeck summarizes a study conducted by Telos Energy in which we evaluated resource adequacy across the Eastern Interconnection using the open-source modeling platform, GridPath, and publicly available datasets. With a near-term study year of 2028, we analyzed the role...
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 report provides an outline of the current state of Large Load interconnections including data centers. It includes recommended questions for regulators and utilities to develop more robust interconnection processes. It also provides template data collection forms that can be...
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...
