Energy Audits

Energy audits can be classified as under:
• Walk-through audit: A preliminary inspection of site to observe the
  various processes and identify glaring areas of energy waste or inefficiency

• General audit: A detailed inspection of all energy consuming processes
  backed up by past operating data. Identification of all energy conservation
  measures followed by detailed financial analysis for each measure

• Investment-grade audit: Projected operating savings from the
  implementation of energy projects are developed such that they provide a
  high level of confidence. Extensive attention is given to understanding not
  only the operating characteristics of all energy consuming systems, but
  also situations that cause load profile variations on short and long term
  basis.
Energy Audits

Effective energy management strategy
   • O&M recommendations

Renewable Energy Potential Assessment
                    (REPA)

Dependence on conventional energy can be greatly reduced with
the use of modern renewable energy systems.

Ambicales has worked extensively & studied about various
renewable energy technologies that can be applied for offsetting
conventional energy demand in buildings, school/college
campus, temples, industries, etc.
Renewable Energy Potential Assessment
                     (REPA)
We look at facility specific energy demands that can be offset
by the following:
  • Solar energy systems

       •   Solar photovoltaic
       •   Solar thermal
  •   Biomass energy systems
       •   Biomass gasification
       •   Biogas Digester
  •   Hybrid energy systems

Case study
Average power factor of 0.80 will be considered for calculations.
  Average energy consumption over the period is 10035.4 kWh.
  Average power factor penalty over the period is Rs. 2877.44.

The solution is to install Power Factor Correction (PFC). It is
  recommended that the PFC unit be of 15 kVAR capacity. The
  cost of the unit is approximately Rs. 20000.

Projected savings are Rs. 34529/yr with a simple payback period
   (SPP) of 0.57 years or 7 months.

Motor Load Test
A detailed motor load study was undertaken on all continuously
   operating motors, with help of clamp on energy meter to
   measure instantaneous parameters.
Star mode operation of under loaded motors (which are loaded
   below 45 % of the rated capacity) results in improved
   operating efficiency.
