Operational Security in 100% Inverter-Based Power Systems: Experiences from Hawai‘i
The integration of renewable generation in electrical power systems is exponentially increasing for multiple reasons. First, a fast decarbonization of the electrical energy system is a critical milestone to slow climate change and facilitate the decarbonization of other energy sectors, such as transportation and heat. Second, renewable generation from wind and solar have become much cheaper compared to conventional sources like gas, coal, and nuclear. Third, renewable generation is in many cases decentralized, which increases the resilience of the energy system, for example, in the face of natural disasters.

Lighting a Reliable Path to 100% Clean Electricity: Evolving Resource Adequacy Practices for a Decarbonizing Grid
It is the year 2045 in the carbon-neutral southwestern United States. While summer heatwaves have increased in frequency and intensity because of climate change, the region’s abundant solar generation produces tremendous amounts of low-cost energy on hot summer days. This energy not only serves daytime loads but it also charges an enormous fleet of batteries that, aided by wind and geothermal power, discharge overnight to effectively eliminate summertime electric reliability concerns.

Harnessing the Full Potential of Clean Energy: The Role of Southern California’s Utility Distributed Energy Resource Pilots
California is committed to achieving carbon neutrality to reduce the threat of climate change by 2045. This will require deep decarbonization across all economic sectors and necessitate rigorous planning to keep energy safe, reliable, and affordable. Southern California Edison (SCE), a utility that delivers electricity to 15 million people across southern, central, and coastal California, undertook an in-depth analysis to identify a feasible and economical path to realizing California’s greenhouse gas reduction goals and achieve carbon neutrality at the lowest reasonable cost by 2045.

Decarbonization of Electricity Systems in Europe: Market Design Challenges
Driven by climate change concerns, Europe has taken significant initiatives toward the decarbonization of its energy system. The European Commission (EC) has set targets for 2030 to achieve at least 40% reduction in greenhouse gas emissions with respect to the 1990 baseline level and cover at least 32% of the total energy consumption in the European Union (EU) through renewable energy sources, predominantly wind and solar generation.
