2. INTERNAL ROADS :

Road construction and its maintenance inside Mizoram University Campus are carried out depending on availability of fund by Mizoram University. The main internal roads which are all flexible pavements inside the campus is 17.10 kms long as under.

In addition to above, rigid pavements are constructed and maintained in different locations inside the Campus.

3. WATER :

Water is one of the main problem faced by the University since it is setting up in this permanent Campus. From the beginning, the University is depending on rain water harvested and the local water suppliers through vehicle transport as the University is not having perennial water supply throughout the year. Since the year 2010, water is being supplied by the State PHE Department as per availability of excess water. As the State PHE Department also could not supply the present requirement of water for the University till date, rain water harvesting system is useful and has been upgrading depending on availability of fund. The present conditions of water demand and water storage and distribution system inside the Campus is as under:

         Water reservoirs/ tanky are constructed in different locations as seen from above. Some are constructed in the downside of the buildings for rain water harvesting tank while some are constructed in the upside of the buildings for water storage / supply tank. Almost all the buildings inside the Campus are inter-connected with rain water harvesting line for able to collect rain water during rainy seasons. So, the rain water collected is pumping up from its harvesting tank to storage tank by mechanical device i.e. Water Pumps.

          In addition to above RCC Reservoirs, dams are constructed in five (5) locations for rain water harvesting during monsoon period inside the Campus. Out of these, two (2) numbers are using efficiently and the water is pumping up for supply.

          Water is being supplied to different buildings such as Academic Buildings, Offices, Halls, Hostels, Quarters depending on requirement of the users.

           The present requirements of water in a week for the whole campus are worked out as under:

A. Phase-I Area (Main Gate towards Northern Side of the Campus)

B. Phase-II Area (Main Gate towards Southern Side of the Campus)

Grand total of water requirements in a week = Total A + B = 2346750 Litres

4. ELECTRIC POWER :

Source of Power:

Mizoram University primarily receives power through an 11kV line from the Tuivamit Sub-Station, operated by the Power & Electricity Department under the Government of Mizoram. This line spans approximately 20 kilometers, reaching various locations within the university campus. The 11kV line is stepped down at 11 different points across the campus using distribution transformers.

Distribution:

The output from these transformers is fed to various loads, including schools, offices, hostels, and residential quarters, via an extensive underground cable network. Except for the 11kV transmission line from Tuivamit Sub-Station to the university, approximately 99% of our electrical distribution is managed through underground cables, minimizing the need for overhead lines. Rare exceptions utilize Aerial Bunched Cables.

Off-Grid Solar Power Plants:

The university generated electric power from Off-Grid Solar Power Plants with a total capacity of 780kVA, installed in 2012 under the Ministry of New and Renewable Energy (MNRE). While these solar plants were efficient, the batteries and other components require regular maintenance and replacement, leading to high maintenance costs over time. To reduce these costs, we have proposed converting 600kVA of our 780kVA Solar Power Plants to an On-Grid system. This initiative, approved by the Building Committee, is expected to minimise our energy usage from Grid line and lower our electricity bill.

LED Lights:

Approximately 85-90% of ordinary lights on campus have been replaced with energy-efficient LED lights.

Emergency Power Backup:

For emergency purposes, Mizoram University has strategically installed seven Diesel Generators (DGs) at various key locations across the campus to ensure uninterrupted power supply during outages. These generators are reserved primarily for academic and official purposes, ensuring that essential university operations continue smoothly even in the event of a power failure. The details of these DGs and the specific areas they support are as follows:

1. 2 x 200kVA Diesel Generators:

• • School of Physical Sciences (SPS): One of the 200kVA DGs is located at the School of Physical Sciences. This generator provides reliable backup power specifically for the SPS building, ensuring that all scientific research, experiments, and academic activities within the school can continue without interruption during power outages.
  • Auditorium: The second 200kVA DG is dedicated to the university auditorium. This facility often hosts important events, lectures, and gatherings, making a steady power supply crucial. The DG ensures that such events can proceed seamlessly, maintaining the university’s schedule and commitments.

2. 4 x 125kVA Diesel Generators:

1. • Near Engineering Cell: One 125kVA DG is stationed near the Engineering Cell. This generator not only supports the Engineering Cell itself but also extends its backup power to the Administration (ADM) building, the Department of Examination, and the School of Education and Humanities. This ensures that administrative functions and academic activities in these departments are not disrupted.
   • Near Guest House: Another 125kVA DG is installed near the university’s Guest House. This generator provides backup power to both the Guest House and the Multipurpose Hall, ensuring that guests and events hosted at these venues experience no inconvenience due to power interruptions.
   • Near School of Life Sciences (SLS): A 125kVA DG is dedicated to the School of Life Sciences. This generator supports all the departments within the SLS, as well as the School of Earth Science (SES). The continuous power supply is vital for the preservation of research samples and ongoing scientific studies in these departments.
   • Near School of Social Sciences (SSS): The fourth 125kVA DG is located near the School of Social Sciences. It provides backup power to the SSS building and the Punjab National Bank (PNB) branch located within the campus. This ensures that both academic activities and banking operations remain functional during power outages.

3. 1 x 600kVA Diesel Generator:

• • National Institute of Orthopaedically Handicapped (NIOH): The largest DG, with a capacity of 600kVA, is designated for the National Institute of Orthopaedically Handicapped. This generator ensures that all critical services and operations within the NIOH have a stable power supply, which is essential for the institute’s healthcare and rehabilitation services.

These strategically placed Diesel Generators form a robust backup system that supports various critical and high-priority areas within Mizoram University, ensuring that academic, administrative, and healthcare activities can proceed without disruption, even during power failures.

Energy Efficiency Practices:

To further our energy-saving efforts, we utilize day/night sensor switches for LED street lights and high mast lighting. These sensors automatically switch lights on and off based on ambient light conditions, preventing unnecessary energy wastage.

Energy Consumption and Load:

The total connected load of Mizoram University is approximately 2500 kW. Our average monthly energy consumption is around 120,000 kWh, resulting in an electricity bill ranging from Rs. 6-10 lakhs per month, at a rate of Rs. 8.65 per unit.

Energy Usage Breakdown:

Electric Energy Utilization:

• Electric energy is utilized across various areas within the university, including academic buildings, offices, hostels, street lights, compound lights, and residential quarters. These diverse areas demand a consistent and reliable power supply to ensure smooth and uninterrupted operations. Academic buildings require energy for lighting, laboratory equipment, and computing facilities. Offices use power for administrative functions, while hostels need energy for lighting, heating, and student amenities. Street lights and compound lights enhance campus safety and security, while residential quarters ensure comfortable living conditions for faculty and staff.

Billing and Tariff Categories:

• The energy usage for residential quarters is billed under a domestic tariff. The domestic tariff rates are structured as follows:
  • First 100 units: Rs. 4.8 per unit
  • 100-200 units: Rs. 5.5 per unit
  • Above 200 units: Rs. 5.9 per unit
• Contractors, canteens, shops, and other commercial facilities are billed under a commercial tariff, reflecting their higher energy consumption and commercial nature of operations. The commercial tariff rates are:
  • First 150 units: Rs. 6.1 per unit
  • Above 150 units: Rs. 6.25 per unit
• This differential billing ensures fair and appropriate charges based on the type and extent of energy usage, promoting energy conservation and efficient use of resources.

Consumer Distribution and Revenue:

Currently, there are 36 commercial consumers and 146 domestic consumers within the university. These consumers contribute to the overall energy revenue, generating a total of approximately Rs. 2.5 lakhs per month. This revenue is crucial for maintaining and upgrading the university’s electrical infrastructure, ensuring continuous power supply and supporting the institution’s energy management initiatives. The careful structuring of tariffs allows for the effective management of energy resources and supports the financial sustainability of the university’s electrical systems.
