  U.S. Interconnection Queues Have Unprecedented Amounts of Renewable Energy and Storage Grid interconnection, the process of connecting generators or energy storage to the electric grid, has emerged as a significant obstacle to the energy transition in the United States. From 2000 to 2010, the U.S. averaged between 500 to 1,000 new annual transmission interconnection…

For long-term transmission planning, the topology of the existing transmission grid is typically assumed to be fixed, and not a decision variable. But this may be about to change in the U.S. with FERC Order 1920, which requires consideration of transmission switching among other technologies. Using transmission switching as a decision variable can provide significant…

  Challenges in Forecasting Long-term Energy Demand in California Just as you might plan how to advance in your career, train for a big race, or save money for a trip, forecasting energy demand allows governments, utilities, and other businesses to plan for future energy needs. Such forecasting paints a valuable view of the future,…

  Motivation for Grid-Forming Technologies in Germany To guarantee a safe and stable system operation, the transmission system is designed to withstand different disturbances. In this context the Continental European power system can balance sudden power imbalances of up to 3 GW if it stays interconnected and all grid users comply with grid code requirements.…

  Challenges Arise The landscape of energy demand and generation forecasting is barely recognizable when compared to just a decade ago. Resources used to be mostly dispatchable, and demand curves followed a familiar pattern. Today, though, grid operators must consider things like non-dispatchable, utility-scale renewables; retirement of traditional generation; behind-the-meter solar generation; demand response; energy storage;…
