PEC released a study that quantified public-health damages from onsite natural-gas power at the Vantage VA2 data center and is hosting a public Q&A to present findings and take questions.

Main announcement: PEC (Piedmont Environmental Council), working with the Harvard-affiliated EmPower Analytics Group, released a study finding that onsite natural gas combustion turbines at Vantage VA2 could cause $53 million–$99 million per year in health-related damages (primarily premature mortality and respiratory/cardiovascular disease), and estimated particulate impacts would reach more than 2.5 million people in the region. The study modelled PM2.5 emissions permitted at Vantage VA2 and concluded impacts are significant despite the site being permitted as a “minor” rather than “major” source.
Background and implementation details: PEC commissioned the analysis because Virginia DEQ and WMCOG have not publicly modelled onsite generation impacts; DEQ has permitted ~10,000 generation units in the region. Vantage VA2 was permitted and modified its site plan in June 2023 to add eight natural gas turbines, becoming Loudoun’s first data-center-scale microgrid. Digital Realty’s Digital Dulles project proposes 23 natural gas turbines (nearly three times Vantage’s) and will require a public special exception under updated county rules; PEC has requested a DEQ public hearing on that air permit.

Event details (public presentation/Q&A hosted by PEC):

When: Thursday, April 9, 7:00–8:30 p.m.
