What is Energy Audit?
Identifying the energy wastages in a systematic way through monitoring, measurement, analysis and evaluation, documenting it, finding the opportunities for energy conservation and recommending the energy performance improvement action plans to the organizations/ plant/multistory commercial complexes without compromising on quality, quantity and comfort of the workmen.
Energy audit requires lot of planning ,monitoring ,measurement ,analysis ,evaluation ,preparation of energy audit report, recommending energy saving projects, quantifying energy saving in KWH /year and in monetary terms RS/- year as well as payback periods in months.

1-Power Quality Analysis for operational / Network problems:
The Harmonic Study is carried out to check the Harmonic distortion levels in the network and to subsequently identify the Source of Harmonic distortion.
A Harmonic Study will:
- Identify the source of harmonic distortion whether from Load side or Source side.
- Harmonic distortion shall have negative effect with other network components. It shall verify the same and suggest measures and solutions to avoid the negative interaction.
- Compliance with international standards like IEEE 519 or EN 610000
- Defining type and rating of PFC equipment for these networks.
- Design parameters of Harmonic Filters if required with their rating and Location.
- Offering other solutions for mitigating harmonics.
We carry out Load flow analysis on Mains and major Loads& following Parameters from 1 Hour to 7 days.( Maximum, Minimum and Average values
Active Power& Energy (KW& KWH), all phases & equivalent
Analysis of above data shall help to determine how the system will operate in normal cycle and emergency conditions and during different parts of day or Week. P.F compensation system, real time , Automatic or fixed installed in the network are also checked for their effect on the network.
The Load flow analysis has following advantages
