• Experience Sets Us Apart

  ESI has delivered facility-engineering, controls integration, operations, and maintenance (O&M) services for an array of biogas utilization facilities at anaerobic digester sites nationwide.
  
  We understand the unique challenges of AD biogas utilization projects—particularly with regards to integration of the biogas utilization facility with the digester to achieve maximum capacity operations.

  
  

   

• Attention to Detail

  ESI’s outstanding ability to deliver seamless integration of multiple technologies (mechanical, electrical, and controls) supplied by multiple equipment vendors enables us to produce a unified operating facility—designed to maximize safety, performance, and up-time
  
  ESI is often able to deliver significant savings in construction costs through its advanced 3D design capabilities and meticulous attention to detail.

  

   

• Best-in-Class Solutions

  While ESI is technology agnostic, as a true third-party engineer we maintain relationships with virtually every one of the leading RNG technology suppliers in the industry.
  
  No single approach works for all projects.  Feedstocks and desired end-products vary. A solution that suits a large operation may not make sense for a smaller one.
  
  No matter how small or large your project or what your desired end product, we’re committed to providing clients with best-in-class solutions optimal for the unique needs of each and every project.

  

• Balance of Plant (BoP)

  ESI sources best-in-class ancillary components to support all its AD gas utilization projects. Now, clients can also take advantage of our new partnership with TransTech Energy, for key supporting BoP components.
  
  Offering nationwide access to over 300,000 square feet of fabrication facility space—and industry-leading custom vessel and equipment fabrication and packaging—TransTech's capabilities support balance of plant (BoP) fabrication requirements for faster projects coupled with superior in-house quality control.
