The article discusses the urgent need for integrating transmission planning and interconnection processes in the U.S. energy sector to address the challenges posed by rapid load growth, backlogged interconnection queues, and other compounding issues. As the demand for electricity rises, particularly due to the proliferation of data centers, the current system is under strain, leading to reliability concerns and increased costs for consumers. The authors argue that while short-term fixes are being explored, a more sustainable solution lies in modernizing and harmonizing the planning processes to ensure that new generation and transmission infrastructure can be developed efficiently and cost-effectively.
Furthermore, the article highlights the historical significance of open access and competitive wholesale markets, which have provided value to customers. However, the increasing delays in interconnection processes threaten these principles. The authors advocate for a comprehensive approach to planning that balances immediate needs with long-term infrastructure development, emphasizing that an integrated system will not only reduce costs and improve reliability but also support the transition to a more resilient grid capable of accommodating future demands.
