Datacenter Dangers #27 – Higher Power More Ill Effects

Higher voltage, higher current, higher power: More means greater effects. More energy into the datacenters but also inescapably more energy into the ill side-effects: Childhood leukemia, “stray voltage”, greater ground-currents and other tectonic effects including toxic rumble, toxic hum, toxic power-line harmonics, heat-island / weather modification.

1) Childhood leukemia / ELF magnetic fields

ELF magnetic fields from power systems are classified by IARC as “possibly carcinogenic,” mainly due to childhood leukemia epidemiology.

2) Stray voltage / neutral-to-earth voltage

Large electrical systems can create neutral-to-earth voltage and contact voltage; recognized especially in livestock/ag settings, with shock/behavior/health/productivity effects at sufficient current.

3) Ground currents / earth-return / infrastructure coupling

Ground currents and induced currents are real engineering hazards: corrosion, pipeline interference, transformer stress, harmonics, and safety issues: “ground-current and geoelectric infrastructure effects.”

4) Toxic rumble / toxic hum / low-frequency noise

Substations, transformers, transmission lines, cooling systems, and backup generators can create low-frequency tonal noise/hum; low-frequency noise is associated with annoyance, sleep disruption, stress, and community complaints.

5) Power-line harmonics / dirty power / nonlinear loads

Data centers are nonlinear electrical loads; UPSs, servers, VFDs, and power electronics can produce harmonic distortion. Harmonics cause overheating, equipment stress, neutral currents, transformer noise, and power-quality problems.

6) Heat-island / local weather modification

Nearly all power entering a data center exits as heat. Waste heat can contribute to local heat-island effects and microclimate impacts. “Weather modification” – “local microclimate / urban heat impacts.”

Doubly intensified higher-voltage power pathways above ground (500 kv vs 230 kv power lines) will inescapably also intensify (double) ground currents and possibly cause substantial redistribution of those telluric pathways; moreover, the very extreme intensification of the power gulping to one comparatively tiny ‘white-hot spot’ (versus houses and businesses using the electricity spread across the entire county surface area) will very likely create an incredible and unpredictable intensification of the local ground currents “feeding” the Datacenter electricity black-hole — in at least one strong opinion, this hidden danger may be the overwhelming contributor to ill-feelings, upset, ill-ease, illness, disease in regards to the entire issue. “Take all of the sunlight from the county and focus it into a few LASER beams aimed at a Datacenter. Think that way of the massive energy concentration and possible power flow redistribution; just imagine the possibilities gone wrong: Eminent Domain focused into Profound Disdain where an egregiously unequal burden is set upon a few unluckies.”


PEPCO has applied to the Commission to rebuild an existing 230 kV overhead transmission line and construct a new 500 kV overhead circuit on existing right-of-way from the Dickerson H Substation in Montgomery County to the Maryland/Virginia state line.

The CPCN application has been docketed as Case No. 9883: https://webpscxb.pscmaryland.com/DMS/case/9883

This docket will contain all the filings, schedule information (including the pre-hearing conference and public comment hearings), and rulings in the case.

A Datacenter adjunct (i.e., a large fresh-water storage pool) has been proposed for the old Quarry lands. The quarry-related item is mostly about Travilah Quarry/Hunting Hill Quarry being studied as a future raw-water storage reservoir, partly because regional data centers increase Potomac Basin water demand.

Travilah Quarry is an active/long-running aggregate quarry near Rockville/Travilah. Water agencies have studied converting it after mining into emergency/backup water storage for WSSC/Washington Aqueduct. That’s connected to datacenters only indirectly: datacenters are one pressure on regional water and energy planning, not necessarily the proposed use of the quarry land itself.
