What Makes Us Different?

• We Design it Like We Own it

  Our engineering design work is informed by a real-time feedback loop of ongoing project data—supporting continuous improvement that also incorporates recommendations and lessons learned from our own operations and maintenance field service teams.
  
  We design it like we own it, because we know, from our own 'hands-on' experience, what it takes to maintain and manage your facility for maximum operational efficiency—and profitability. Learn More.

  

   

• SCADA & Controls

  As a biogas industry pioneer, ESI was an early proponent of advanced Supervisory Control and Data Acquisition (SCADA) and controls systems for renewable energy facilities.
  
  Today, we’re the industry leader in cutting-edge SCADA system development, with over 30 SCADA/Control systems installed, all uniquely tailored to the biogas industry. Learn More.

  

   

• 24-7 Maintenance - Your Parts Are On The Way

  In 2017, the decision was made to annex the Sisters Airport to ESI's property holdings, following in overwhelming majority vote by the citizens of Sisters. The airport provides ongoing benefit to the community while supporting ESI's rapidly expanding business needs.
  
  Maintaining an airport at our headquarters facilitates efficient travel and supports rapid, responsive service for any urgent needs of our O&M clients. Learn more.

  

   

• Predictive Maintenance

  Our own in-house, experienced SCADA and Control personnel design, fabricate, and install fully custom SCADA and Control systems, to deliver 360° visibility across all your projects and give you the power to identify and optimize project and program-wide inefficiencies, reduce downtime, and maximize capacity.
  
  With the added option of predictive maintenance, you can identify and address maintenance issues before they lead to equipment damage or shutdown. Learn More.
