In business since 1973, Moser Energy Systems is a leading generator manufacturer and service company.  In an ever-changing world, with ever-increasing uncertainty, line power cannot always be relied upon. When disaster strikes, you want the confidence of knowing that your business will still be in business.

Oil & Gas

Our industry-leading generators have been tested and proven to run in all oilfield climates, from the bitter cold of North Dakota to the extreme heat of West Texas.

Commercial & Industrial

Our conventional generators and innovative HybridGen technology allow you to work more efficiently while also reducing noise and producing fewer greenhouse gas emissions.

Demand Response & Grid-interactive

Because of increasing grid instability and volatility in power prices, Moser’s generators can serve an essential role in stabilizing the grid and provide significant savings and revenue generation for the end-user.


We provide our time-tested and proven service and reliability to ensure that microgrids are clean, efficient, and more reliable than the transmission grid.
