Energy audit services for buildings and industries

Firstgreen adopts the most scientific and result oriented approach for Power Quality Analysis and Energy Auditing. A detail instrumented performance evaluation backed by computer Interfacing is carried out for each and every load point, Based on the measured data, detailed analysis is done to find out the scope of improvement in overall performance and points where energy can saved or better utilized. The same is submitted in the form of detailed report.

• 1. Electrical energy audit
  • Study of overall load profile including voltage, current kW load, kVA load, PF and harmonics.
  • Study of load profile of individual transformer, Feeders and major motors.
  • Power factor improvement.
  • Max. Demand analysis, solution for avoiding penalties.
  • Most economical voltage level study.
  • Capacitor performance assessment.
  • Calculation of specific power consumption.
