The energy transition is trying to fit a square peg into a round hole—variable, renewable generation into a grid built for thermal generators. To stop climate change, we must adapt this system as cost-effectively and as quickly as possible to deliver variable generation, often from far-flung sunny and windy regions, to load centers. Grid-Enhancing technologies…

Nowadays, many of our most important apps and programs are open source or contain open-source components. In recent years, open-source code has also come into the energy space, where most tools and models had previously been in-house operations (albeit with some notable exceptions). A rather long list of current open-source energy-related models can be found…

Rising levels of inverter-based resources and the accompanying retirement of the synchronous machine fleet is changing the dynamics of how the system achieves/ensures stability. However, the shift is not toward a network made up solely of inverter-based resources. Synchronous machines will remain present into the future and include the synchronous generators of today (at least…

ESIG recently released a report titled Redefining Resource Adequacy for Modern Power Systems, which laid a foundation for new ways to think about resource adequacy and reliability as the grid decarbonizes. In that work, we laid out six principles to guide changes to the way we consider and quantify resource adequacy in an era of…

In order to combat climate change, there is a global need for deep decarbonization, and all sectors that produce carbon dioxide (CO2) must play a role. In 2019, global CO2 emissions from fossil fuels totaled ~33 gigatons, with ~41 percent coming from the power generation sector. The good news is that there are solutions available…
