AI generated summary

The Texas and California grid operators have been rated as having the best generator interconnection processes among U.S. regional transmission system operators, according to a new scorecard by Advanced Energy United. On the other hand, the PJM Interconnection and ISO New England scored poorly, with PJM receiving a D-minus and ISO New England a D+, particularly in the areas of regional transmission planning and interconnection alternatives.

The report from AEU highlights the challenges in the grid interconnection process, crucial for ensuring reliable power supplies as aging power plants retire. With significant amounts of planned generation and energy storage seeking to connect to the U.S. grid, the slow progress in completing interconnections poses risks to system reliability. The report's assessment, based on public data and stakeholder input, indicates a need for further reforms across the regional grid operators to improve the interconnection process.
