  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;…

  The Interconnections Seam Study, led by the National Renewable Energy Laboratory and completed in 2018, provided one of the first in-depth analyses of benefits associated with a North American high-capacity multiregional HVDC transmission overlay, referred to as a macrogrid. In 2022, ESIG developed a report on macrogrid design study requirements.  Further work is ongoing via…

  Tuesday, June 20, 2023, 4:30 p.m. – I had just exited a 90-minute online knowledge-sharing session with fellow Global Power System Transformation Consortium (G-PST) system operators in the U.S., Australia, and Europe discussing best practices for managing transmission constraints in a system with high levels of inverter-based resources (IBRs) like wind and solar generation.…

The goal for our energy future in Hawaiʻi is clear: Eliminate carbon emissions and rely on renewable resources every time we turn on a light, share a meal, or take a ride. But, as the saying goes, a goal without a plan is just a wish. We’ve already made significant progress. More than one-third of…
