Cummins engineers use TEE and TEEf to design Hybrid systems that improve overall efficiency achieving best OpEx savings
Reduction in genset run hours is not an accurate and predictable estimate of actual fuel savings and system efficiency

Optimized Energy Site Performance
Successful TCO Reduction Deployment
CPG designed and deployed the best solution within the IGT constrains/KPIs
normalize the $$ and use other no geo/or name
IGT (Low TCO 1nd Lowest Capex 2nd) TEE
Fuel provided by MNO changed their strategy
Final IGT KPIs were modified (Low Capex 1st Low TCO 2nd)
In the Context of company support and global reach (Example from the field? Logos? Pictures?)
