2021 Will Present New Challenges for Congestion Revenue Rights (CRRs) in CAISO

LCG, September 4, 2020--LCG Consulting completes a comprehensive congestion analysis for 2021 in California ISO (CAISO).

Market participants are busy preparing for the Congestion Revenue Rights (CRRs) allocations and auctions coming over the next weeks. They should pay attention to the changing system conditions that will impact their ability to acquire new CRRs and greatly affect the value of these products.

The state's energy market is navigating profound changes, from ambitious renewables standards to energy shortages and unprecedented growth in storage.

By performing a detailed market analysis, forecasting the hourly operations of CAISO through rigorous software simulation, LCG was able to determine that congestion patterns will be different than in previous years. For example, prices in the North of the State will not track the prices in the South as closely as they have in previous years. This divergence is due to a number of interrelated factors, including:
  • The retirement of many natural gas power plants in the Edison footprint
  • Significant transmission outages that will disrupt normal power flow patterns
  • New storage and solar
  • Limited capacity in the early evenings causing additional imports

Changes in congestion patterns indicate that certain market participants will be at risk when supplying power to locations different than where it is procured -- especially if they do not have congestion hedges or are hedging the wrong paths. Others may benefit greatly.
