Increasing efficiency, decreasing downtime of your electric power generator |
E/One Gas Stations combine monitoring and control systems onto a single skid |
The E/One Gas Station is a modular approach that combines monitoring and control systems onto a single skid, customized to meet specific power plant requirements and budgets. 
Gas Station modules include:
Power utilities and independent power producers are increasingly concerned with upfront capital expenditures and subsequent on-site engineering and installation costs. They also require accurate, real-time monitoring information so that generator efficiency and generator performance can be maximized — and downtime minimized. The E/One Gas Station addresses each of these concerns and allows power plant operators, together with E/One, to configure targeted solutions for original equipment supply and retrofit applications.
Contact E/One for detailed specifications of Gas Station configurations.
