Lower Merion Puts Data Center Siting Rules on the Table
Lower Merion’s Planning Commission is scheduled to review proposed data-center zoning rules Monday, Hoodline reported. The draft would narrow eligible locations and require applicants to address water capacity and equipment decommissioning.
The proposal is not yet law, but it gives prospective developers a clearer picture of what local approval could require.
The draft would confine data centers to a narrow Light Industrial district in Bala Cynwyd, cap height at 60 feet and require a 1,000-foot setback from residential zoning. Applicants would also need water and wastewater capacity studies, drought plans and equipment decommissioning plans. No affected project or construction delay has been identified.
Separately, analysis in Datacenter Dynamics argues that European data-center expansion remains constrained by transmission, storage and connection limitations, even where renewable power is available. It describes an Irish shared-substation example with a claimed two-year schedule gain, but the comparison is not independently documented in the available reporting.
Key Points
- Local scrutiny is taking different forms. Lower Merion’s draft combines site limits with resource planning, while Tulsa recently proposed larger setbacks for its biggest facilities. Neither proposal has been adopted.
- The European analysis reinforces a distinction for site selection: power available in a region is not necessarily power deliverable to a particular facility.
Implications
If Lower Merion adopts the draft, prospective applicants would face a narrower choice of sites and additional studies and plans. The final requirements could still change.
Shared connections may offer a way to coordinate generation and data-center demand, but the reported Irish example does not establish a replicable schedule saving.
Watchpoints
Watch
Whether the Planning Commission advances or changes Lower Merion’s draft, and whether later review identifies effects on specific sites.
Watch
Whether shared-connection arrangements produce documented agreements, energization dates and verifiable schedule gains.
Fallout
A local zoning proposal is the clearest prospective step; European grid analysis adds context rather than a new project milestone.
Lower Merion Data-Center Zoning
The township is considering its first zoning rules specifically for data centers.
Fresh developments
Hoodline reported that the Planning Commission is scheduled to review a draft restricting locations and requiring water, drought and decommissioning plans.
Why we noticed
The proposed rules would shape both where facilities could be built and what applicants must address. They have not been adopted.
Watch for:
- Commission recommendations, public comment and a possible commissioners’ vote.
- Any identified effects on prospective sites.

European Power Connections
Grid delivery and connection constraints remain relevant to data-center expansion.
Fresh developments
Datacenter Dynamics published analysis describing shared energy hubs and an Irish shared-substation example.
Why we noticed
The analysis highlights a potential coordination approach, but does not establish a new utility commitment or independently verify the example’s claimed schedule gain.
Watch for:
- Documented connection agreements and energization dates.
- Evidence that claimed schedule improvements can be replicated.

Final Thought
The practical test for expansion remains local: a viable site needs rules that permit it and power that can actually reach it.
