EESL collaborates with NITI Aayog for energy efficiency
29 Apr 2017
NITI Aayog has effectively engaged Energy Efficiency Services Limited (EESL) to retrofit LED lights, energy- efficient ACs, ceiling fans, energy saving ACs, energy-efficient water pumps and install a chiller system in the NITI Aayog premises, in a Rs2.67-crore project that would result in an annual saving of Rs1.02 crore.
Besides saving in costs, the project would result in annual energy savings of 11.4 lakh kVAh and annual reduction of 966 tonnes of CO2 crore.
EESL has retrofitted 3,061 LED lights, 591 energy efficient fans, 415 energy efficient air conditioners and installed 2 energy efficient chillers. Additionally, other energy efficient appliances such as energy efficient water pumps, APFC control and CEMS (Central Energy Management Systems), which tracks the buildings energy consumption has also been installed. With these interventions, the Bureau of Energy efficiency (BEE) has certified NITI Aayog building with 5-star rating with Energy Performance Index of 72 (kWh/sqm/annum).
NITI Aayog initiated the energy efficiency interventions in March 2014 in consultation with EESL. EESL analysed the connected load of NITI Aayog building and based on the highest components of energy utilization, target areas for interventions were identified. Additionally, monitoring and verification of the interventions was also carried out through physical verification of the replaced energy systems with wattage and operating hours by EESL.
The retrofitting and installation is executed in two phases with different models of implementation process.
Phase-I was done through PMC (Project Management Consultancy) mode in which entire capital cost was paid upfront by NITI Aayog and entire savings arising out of lower electricity bills accrue to NITI Aayog.
The chiller systems, which is already installed in NITI Aayog under Phase-II, where EESL has implemented the project in Energy services Company (ESCO) shared saving model through collaboration with the Central Public Works Department (CPWD).
Under ESCO model, the upfront capital cost is borne by EESL and the resultant savings from projects are used to repay for EESL investments on deemed basis.
