Last issue we counted the Mid-Continent, the oldest iron on the board. This week: the country’s biggest gas basin. The Marcellus and Utica span three states in one book, Pennsylvania carrying 87 percent of the horsepower, and the count reads like no other basin we have published. Half of everything set since 2020 is turbine horsepower, the operator league is pipelines and processors nearly top to bottom, and not one of the 639 sets carries a compression vendor’s name on the public record.
This is Iron Count No. 04, a four-page brief of what six and a half years of the record holds for Appalachia. In this article: the setting pace with per-state coverage dates printed honestly, the newest cohort ranked, the engine families and the turbine story, the ownership league with corporate parentage verified against filings, and the rental layer the record cannot see, bounded from the vendors’ own disclosures.
Page one is free every Thursday. The full count is not: the $100 read opens pages two through four, the league tables, the PDF for your files, and everything Tuesday and Sunday carry.
Behind this brief sits the complete read: a Northeast five-year supply and demand report, the standing fleet, what gets built, what retires, and where demand lands through 2031. It is for sale as a standalone, no subscription required. Message us and we will send the scope and the price.
