Project Detail

Producing renewable natural gas from dairy farm waste

Total Cost
$40 million
Date Completed


Nacelle Solutions, LLC, needed an engineering design partner to help upgrade biogas from four dairy farm digesters into renewable natural gas (RNG).


Bartlett & West provided site-civil, electrical, mechanical and process design solutions, streamlining the overall design into a templated approach applicable to all four farms.


The projects were completed in 12 months despite the need for remote coordination from a geographically dispersed team during the COVID-19 global pandemic. Each site is producing about 200 standard cubic feet per minute (SCFM) of renewable natural gas, which is a significant source of revenue for the client.
