Prices at PJM Interconnection’s 2025/2026 base residual auction (BRA) spiked to $269.92/MW-day for most resources in the wholesale power market, pointing to a tightening supply-demand balance that could have significant implications for the regional transmission organization (RTO). The 2025/2026 BRA—a competitive capacity auction that procures power supply resources in advance of the delivery year to […]

After Hurricane Beryl laid a path of destruction through the greater Houston area, the storm’s impact on the local power grid is having an outsized effect on the ongoing debate about the future of Texas’ energy and electrical infrastructure. The lessons we take from this incident, which left 2.5 million people without power at the height […]

The U.S. transmission and distribution (T&D) network is reliable and well-maintained, but as renewable energy continues being added to the grid, and demand increases due to growing data center needs and the electrification of transportation and manufacturing processes, work is necessary to keep up with the changing times. The U.S. government understands the need for […]

SAIDI (System Average Interruption Duration Index) and SAIFI (System Average Interruption Frequency Index) are widely used reliability indices that measure the performance of power distribution systems. SAIDI represents the total duration of interruptions for an average customer over a given time period, typically a year. It is calculated by taking the sum of all customer […]

Global communities increasingly turn to distributed energy resources (DERs) to boost their local economies and enhance energy resilience. Generating and managing power locally cuts energy costs and fosters sustainable development. Recent successes in various cities and towns showcase how DERs can drive significant economic growth. As a result, it has become a viable strategy for […]

It’s no secret that the U.S. electric power system has undergone a remarkable transition that continues today.
