Dominion ordered to directly assign some transmission costs to data centers

Virginia's utility regulator has ordered Dominion Energy to change how it splits up the cost of new power infrastructure, so that data centers pay more directly for the grid upgrades they cause. Dominion had wanted to raise its transmission charge, known as Rider T-1, to recover about $1.5 billion in costs. The regulator, the State Corporation Commission, approved a scaled-back version of that increase, cutting the proposed monthly bump for a typical residential customer from $2.90 to $0.94.

Beyond that rate case, the bigger change is a new rule requiring data centers and other large "direct connect" facilities to pay a mandatory contribution toward the substations and transmission lines built specifically to serve them, rather than spreading those costs across all ratepayers. Dominion has 90 days to file the details of this policy. The commission also left the door open to extending this cost-shifting approach to larger, more expensive transmission projects down the road, possibly assigning those costs to Dominion's biggest industrial customers.

For homeowners in Dominion's Virginia service territory, this means some of the financial pressure from data center growth on electric bills is being redirected toward the companies building those facilities, rather than falling on households. It does not change your home's eligibility for any efficiency or rebate programs, but it may help slow the pace of rate increases tied to data center demand in the state.
