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…

A case study in South Australia Under Frequency Load Shedding (UFLS) is the last resort “safety net” that protects consumers from a black system event when severe disturbances occur. It involves the automatic disconnection of large quantities of load in millisecond timeframes to rapidly rebalance the power system and arrest frequency decline following a severe…

The U.S. has been investing between $20 billion and $25 billion annually in improving the nation’s transmission grid. Over 90 percent of these investments are justified based on: (1) the local reliability criteria of transmission owners, including the replacement of the many aging transmission facilities built before the 1970s; (2) the local and regional reliability…

Hydrogen has a central, yet mostly invisible, role in today’s global economy. Its primary uses are in the manufacture of ammonia for agricultural fertilizer, in the refining process for transport fuels, and in numerous chemicals used in a wide range of products. Most of today’s hydrogen is made from processing natural gas and is termed…

At risk of stating the obvious, we need to lower emissions, not only from the electric power sector, but also from transportation and other energy-consuming sectors. Agreement on this is evident in the number of states, regions, and countries that are making ambitious commitments to decarbonize. However, having the societal and political will to promote…
