Definition
Grid interconnection is the formal, regulated process by which a new power generator, or a large new consumer of power such as a Bitcoin mine or data center, gets permission to connect to the electric grid. Before any large facility can plug in, grid operators must study how it will affect voltage, stability, and existing transmission infrastructure, then determine what upgrades (new lines, substations, transformers) are required and who pays for them. For loads above roughly 20 MW, this means connecting directly at the transmission level, triggering a detailed engineering and cost-allocation study.
The queue problem
In many regions, interconnection has become a major bottleneck. "Queues" of projects waiting for connection studies stretch for years, clogged by speculative applications that never get built. In the United States, FERC's Order No. 2023 reformed the process with a "first-ready, first-served" cluster-study approach, stricter financial commitments, and standardized modeling to clear the backlog. Regulators are now extending similar large-load interconnection rules to fast-growing electricity consumers like AI data centers and mining operations.
Why it shapes mining strategy
Interconnection timelines and costs often decide where mining gets built. A site with existing transmission capacity, or one that can connect as a flexible, curtailable load, can come online far faster and cheaper than one requiring grid upgrades. This is a key reason miners gravitate toward behind-the-meter and stranded generation, co-locating directly with a power source sidesteps much of the public-grid interconnection gauntlet entirely.
