According to reports, huge electricity bills of various government buildings in Uttar Pradesh are on their way to becoming a thing of the past, as recommendations of the energy audit undertaken by the Bureau of Energy Efficiency point towards possibility of huge energy saving in these buildings. Documents available with TOI indicate that after only partial implementation of the recommendations, the average monthly saving of Shastri Bhawan was Rs 7,42,158, while of Bapu Bhawan Sachivalaya was Rs 1,98,540. Shakti Bhawan, which houses the office of the UPPCL registered a monthly saving of Rs 2,90,075.
The other government buildings, which registered significant average monthly savings, include Vishveshvaraiya Bhawan, UPRNN (Rs 7,346), UP Awas evam Vikas Parishad (Rs 29,869), Indian Telephone Industries Limited (Rs 43,470) and UP Jal Nigam (Rs 46,392).
Officials say results of the energy audit carried out were so good the Bureau of Energy Efficiency asked Uttar Pradesh Power Corporation Limited, the State Designated Agency for the energy audit, to bring more buildings under the ambit of the energy audit. The implementation of the recommendations of the energy audit also gave the UPPCL to cheer about, as UP was among the top-3 performing states as far as implementing the recommendations of the energy audit is concerned.
Of the 20 buildings, which were shortlisted for energy audit, the findings reveal that annual energy saving potential of these buildings is Rs 5.89 crore, while the investment required is Rs 7.76 crore. And the maximum time needed to recover the investment (pay back period) is 26-27 months.
Throwing more light on the Investment Grade Energy Audit carried out on the directions of Bureau of Energy Efficiency, Varalika Dubey, executive engineer of UPPCL, said, “The energy audit was conducted almost a year back and the team came up with its recommendations. Initially, 20 government buildings in Lucknow were subjected to the Investment Grade Energy Audit.” She added that the aim of the entire energy audit was to assess the scope of energy saving. “Buoyed by the results of the implementation of the recommendations of IGEA, the BEE asked the state designated agency to add 10 more buildings for energy audit,” Dubey added.
Some of the recommendations which came up for energy conservation in a building were: Installation of automatic power factor generator, replacement of existing lights with T-5 tubelights or LED (Light Emitting Diode) lights, installation of solar heating systems, installation of new screw chilling plant, installation of variable speed motors, replacement of old motors with new energy efficient star-rated motors, replacement of window ACs by BEE star rated ACs, performance improvement of air handling units, optimisation of contract demand, films on window panes and installation of solar heating systems. Apart from this, load optimisation of transformers in the government offices was also carried out, and UPPCL officials say the transformer of the Shastri Bhawan was ‘underloaded’ while that of Bapu Bhawan Sachivalaya was ‘overloaded’.
During the audit, the team also found that total energy consumed by the buildings is roughly 30% of the state’s energy consumption.
