These amendments, outlined in CCR, title 20, sections 1391 through 1394.2, reorganize the regulations implementing the PSD program, which collects electricity procurement […]

As the global energy transition accelerates, understanding the dynamics of cross-border electricity flows becomes increasingly important. Increased interconnection to help ensure deliverability across and within national borders is important to enable the efficient use of clean energy. A recent article by The Economist highlights that less than 3% of the world’s power is traded internationally, […]

Stories of Grid Decarbonization: Journey Through Different Stages Hourly data tells us the true stories of grid decarbonization. When looking at hourly CFE % across the year, we see significant variations in the availability of clean power. To do this, we use heatmaps, with one block for each hour in the year.  Every grid tells its […]

Both the European clean hydrogen requirements and draft 45V clean hydrogen production tax credit rules in the United States include hourly matching of clean electricity production and consumption to qualify as low-emissions. Registries are quickly developing, with some like PJM and M-RETS already offering limited functionality using hourly certificates. A recent study by CRS finds […]

As variable renewable energy takes center stage with more installed capacity and generation, analyzing the availability of clean power on an hourly, not just an annual basis, is a must if we are to make the smartest choices in getting to zero-carbon grids with increasing focus on decarbonizing the low renewable hours. Leveraging hourly data […]
