One Year After the Texas Blackout: Lessons for Reliable and Resilient Power Systems

One Year After the Texas Blackout: Lessons for Reliable and Resilient Power Systems

In February 2021, Texas experienced an extreme cold snap causing a dramatic electricity blackout that left millions of households without electricity, resulting in over 200 fatalities and economic damages of approximately $100 billion. The Texas blackout has been used to support a variety of claims regarding renewable energy, electricity markets and climate change. We identify the blackout’s drivers and what has been learned since then. These lessons apply to power systems worldwide, including those of the Gulf Cooperation Council and the broader Middle East and North Africa region.

Distribution Hosting Capacity Tool

Distribution Hosting Capacity Tool

This study presents the methodology for the KAPSARC Distribution Hosting Capacity Tool (KDHCT). This tool can support the future of renewable energy in Saudi Arabia. The use of distributed energy resources (DERs), such as solar panels, energy storage and electric vehicles (EVs), is expected to increase. The KDHCT evaluates how many of these assets a particular distribution system can accommodate. The number of DERs and the load that an electric distribution system can reliably accommodate without significant grid upgrades is called its hosting capacity (HC) (Abad, Ma, and Han 2019). HC analysis informs electricity customers and utilities about the best places and times to install DERs and EVs on any distribution system. Thus, utilities can avoid reliability problems and costly distribution system upgrades.

Reliability Implications of Unexpected Tripping of Inverter-Based Resources

Reliability Implications of Unexpected Tripping of Inverter-Based Resources

A recent KAPSARC Instant Insight examined the reliability crisis in electric power grids, and proposed policy measures that can mitigate these risks (Felder 2022). The specific causes for these severe outages and blackouts differ, but the causes of greatest concern are those that result in multiple failures of grid facilities. In 2022, the North American Electric Reliability Corporation (NERC) examined the increasing risks to the grids in the United States (U.S.), in particular hazards to the North American bulk power system (BPS). NERC highlighted a special concern related to the increased deployment of inverter-based resources: the unexpected tripping of solar PV resources that could incapacitate large amounts of generation, resulting in reliability challenges. This issue is particularly important to Saudi Arabia as it pursues the deployment of widespread, large-scale solar power plants.
