Peak Western Conditions Reveal a Changed CAISO

Peak Western Conditions Reveal a Changed CAISO

On September 5th and 6th, 2024, the California ISO (CAISO) was under stress from both within and without. High temperatures, spiking day-ahead prices, import cuts, and wildfires — a problematic milieu. Despite this, real-time prices remained low and neither conservation calls nor emergency alerts made an appearance. Let's dig

Curtailment: When We Throw Away Clean Energy

Curtailment: When We Throw Away Clean Energy

As we approach the end of another shoulder season — a period of lower demand and higher transmission outages — it's a good time to explain curtailment, a crucial yet often controversial aspect of today's grid operations.

SPP Expansion Provides a Blueprint for the Future of the Grid

SPP Expansion Provides a Blueprint for the Future of the Grid

The U.S. power grid is so complex that trivial changes are hard to comprehend and harder to implement. Yet, a recent announcement by the Southwest Power Pool (SPP) is closer to historic than trivial, making it a good case study for a more integrated and efficient grid.

Nearly instantaneously, a significant portion of nuclear generation in New England disappeared. This abrupt outage created measurable effects across the grid that we explore in this post.

Balancing Act in California

Balancing Act in California

While CAISO continues to set renewable generation records, there are worrying signs of regional balkanization of flexibility which could increase fossil fuel generation in an era when many BAs in the West are trying to do the opposite.
