The transition to a clean energy economy is at a critical juncture. As the world races to meet ambitious climate goals—such as the United States’ target of 100% carbon-free electricity by 2035—the electric grid faces unprecedented challenges. One of the most significant barriers to scaling renewable energy is the grid interconnection process—the mechanism by which new power generation and large energy consumers, like AI data centers, connect to the grid. This complex, often slow process is creating bottlenecks that threaten to stall the renewable energy revolution. In this article, we explore the interconnection challenge, its causes, its impact on renewable energy deployment, and the innovative solutions emerging to address it, with a spotlight on how companies like Pacifico Energy are helping to uncork this bottleneck.
The Growing Importance of Interconnection
Grid interconnection is the linchpin of renewable energy deployment. It’s the process through which new energy projects—whether solar farms, wind turbines, or battery storage systems—gain permission to connect to the transmission network. Similarly, large energy consumers, such as data centers powering artificial intelligence (AI), must secure interconnection to draw power from the grid. The process involves rigorous technical studies to assess a project’s impact on grid reliability, often requiring costly infrastructure upgrades to ensure stability.

Historically, interconnection challenges simmered quietly in the background. However, the surge in clean energy demand, coupled with the explosive growth of AI-driven data centers, has brought the issue into sharp focus. According to Lawrence Berkeley National Laboratory (LBNL), over 2.6 terawatts of generation capacity—more than twice the entire U.S. installed capacity—are currently waiting in interconnection queues. Approximately 80% of this queued capacity is low-carbon, yet only 19% of projects queued between 2000 and 2018 reached commercial operation by the end of 2023.
