ERED has comprehensive infrastructure, computational facilities and a team of qualified Engineers for providing energy services like conducting Energy audits and training Energy Managers.  ERED has been rendering the Energy audit and Energy conservation services for a variety of customers for more than three decades and has undertaken audits in several energy intensive industries, thermal power stations (TPS), stationary DG sets, oil refineries, refrigeration and air conditioning plants, star hotels and commercial establishments. From our vast experience, we envisage that there is scope for saving about 5 % to 20 % of the total monthly electrical energy & fuel consumption by implementing the energy conservation measures identified by us.

Technical energy audits (with aims ranging from identifying ways of energy efficiency enhancement to evolution of a new blue print for the energy system) provide insight into the modes of efficient utilization of fossil resources, high-grade energy and exploration of renewable energy solutions.

CPRI have conducted energy efficiency studies along with other Energy Auditors & ESCOs in major buildings like Rail Bhavan, Sanchar Bhavan, IGI Airport and AIIMS, New Delhi.

The studies have identified major energy saving potentials in Lighting system, HVAC system, Water pumping system, etc. By optimizing the use pattern & operational time of various loads, about 10-15 % yearly energy consumption can be reduced/ controlled.
