Northern Virginia hosts more data center capacity than any other location in the world — over a third of global data center supply. That concentration makes Virginia the proving ground for every policy question the opposition raises about data center grid costs. The Virginia State Corporation Commission’s November 2025 order creating the GS-5 rate class is therefore the most carefully developed, most legally scrutinized answer to those questions in the United States. It is not a developer’s proposal or an advocacy position — it is a state regulatory order, backed by months of evidentiary hearings, expert testimony, and formal rulemaking. And its finding is that properly structured tariffs can protect residential ratepayers while accommodating data center growth.
