Which rung of the ladder is narrow
The passage that says the most in Pennsylvania's Executive Order 2026-05 is the count published beside the rules. More than 100 data centre projects appear in public databases; 58 of them have engaged with the Department of Environmental Protection at some level of formality, 15 have applied for at least one permit and 5 hold every permit needed for a first phase. The four figures share no denominator, yet they give four rungs of one ladder: announcement, contact, application, permit.[1]
What the order does is add a rung to that ladder. Before permit review opens, the department now wants a legally binding consent order and agreement from the developer and every local approval in hand; projects leave the fast-track programme and nondisclosure agreements are closed off. It also draws a line on cost: the developer pays for the new generation, transmission and distribution rather than shifting it onto households, the reliability backstop auction is charged to data centres instead of other customers, and under grid stress data centres lose service first.[1]
The measurement that follows is this: megawatts announced in a state are not an indicator of megawatts that will be energised there. Nor can the narrowing from more than 100 to 5 be credited to the new rule on its own, because the count was taken on the day the order took effect; ordinary project attrition and an early-stage pipeline would produce the same spread. The figure that separates the two readings is how many projects sign the consent order and win local approval after the order.[1]
Approval now sits with the city council
On the same day, a city council committee in Memphis sent an ordinance pausing new data centre permits to the full chamber. Its definition of a data centre takes in cooling systems, backup generators, substations and battery storage, so the pause reaches the server hall together with the equipment that feeds it. The three data centres SpaceXAI already runs in the area sit outside it. Protect Our Aquifer describes the window as 12 months to write rules that should have existed for over two years; the Southern Alliance for Clean Energy wants an 18-month pause across five states.[2]
The two decisions come from different tiers of government but squeeze the same point. Pennsylvania makes local approval a precondition of the state permit; Memphis temporarily closes the table where local approval is given. For a developer the practical consequence is that a project's schedule is now set on a council agenda rather than in its own supply chain. Lead times for silicon, memory and transformers have not gone anywhere, but in these two places the next bottleneck has moved ahead of them.[1], [2]
The threshold a reader can watch will be visible by the end of the year. If the order stands, how many of the 58 projects already in contact with the department sign the consent order and secure local approval, and how many new data centre permits are issued after it, will show whether the rule is a gate or a filing step. Until those two numbers are published, anything said about how much of the announced capacity reaches the grid is an estimate.[1]
