Premised on DCF's recent article series centered on data center diesel backup generator technology, the latest episode of the Data Center Frontier Show podcast finds site editors Matt Vincent and David Chernicoff recounting how Aligned Data Centers' Quantum Loophole campus was recently called out by the State of Maryland over a permitting snag in a contentiously approved plan for construction of 168 data center diesel generators, amounting to over 500 MW of backup power generation.

Data centers like Aligned's Quantum Loophole campus, which is being raised on the site of a former aluminum smelting plant, seek to do in Maryland what so many others are doing next door in Northern Virginia. Maryland does want the data center business, but isn't having it without certain qualifications to be met in the form of the state's Certificate of Public Convenience and Necessity (CPCN) licensing process.

As recorded by DCD, in wake of the permitting snag, Maryland officials have wondered aloud about clean energy alternatives, even to the point of expressing incredulity that use of carbon-emitting technology is even on the table -- especially given certain outside realities, not least being Aligned's use of microgrid power in its Plano, Texas data center.

Chernicoff and Vincent sidle up to the conclusion that a modular, incremental technology approach allows for a mosaic of available data center backup power generation solutions including diesel to be used, which the overall industry currently requires. Chernicoff also notes how Tier 4 standards for data center diesel power have gotten significantly cleaner after two decades of refinement.
