The TU is the first academic institution to have initiated the installation of a solar PV power plant on the roof on a megawatt scale in the entire northeast, said University Chancellor Biren Das.
“TU has worked with the developer – Arunachal Pradesh Power Corporation Pvt. Ltd, New Delhi – for 25 years at a flat rate of Rs. 2.42 / kWh in 2018 for the installation of the power plant, ”he said. “The electricity consumption of 11 buildings in 15 buildings in which the solar power plant is installed is currently zero. These buildings can be described as electricity neutral buildings, ”added Das.
While the world is fighting against climate change and looking for alternative ways to generate energy, the TU is prioritizing the use of renewable energies to generate electricity for its buildings and classrooms as part of its “Initiatives for a Sustainable Campus”.
A TU spokesperson said the university is considering five thematic areas – energy, water, waste, natural ecosystems and sustainable building – for its mission towards a sustainable campus. “In order to develop sustainable buildings (also known as green buildings), the university installed a solar power plant with 1000 kWp roof grid connection as part of the SECI (Solar Energy Corporation of India Limited) program for government buildings in RESCO mode (Renewable Energy Service Company) . This has effectively replaced 24 percent of the university’s monthly electricity consumption from October 2018 to July 2020, ”he said.
“The TU purchases electricity from Assam Power Distribution Company Limited (APDCL) at a price of Rs 6.60 / kWh, while the solar power plant only incurs electricity costs of Rs 2.42 / kWh. This means that a solar roof system is much cheaper than buying electricity at commercial prices, ”said Sadhan Mahapatra, associate professor in the university’s energy department, who was involved with the installation of the roof network in the TU.
A TU statement states that the total electricity fed into the university network from October 2018 to July 2020 is 19.68.345 kWh, while the monthly average electricity generation from the facility is 89,470 kWh. The maximum generation in one day is 5,938 kWh and the average daily generation in this period is 2,949 kWh / day. The maximum monthly generation in August 2019 was 1.12.149 kWh.
