Energy Management

---

The campus is beautifully landscaped in a lush green stretch of land spread over 22 acres with a built-up area of 4,56,000 square feet. Being situated away from the main road, it's also free from air and noise pollution.

The institute has taken various Green initiatives and practices to make the campus green.

• Roof-Top Solar Power Plant of 50 kW capacity is commissioned.
• Sewage Treatment Plant (STP) & Reverse Osmosis (RO) plants are installed and the treated water from STP is used to water the plants in the garden.
• Sprinklers are used in gardens to prevent water wastage.
• Rain Water Harvesting system is in place.
• Reverse Osmosis (RO) water treatment plant is installed to get cleansed drinking water and waste water from RO Plant is used to water the plants in the garden.
• Energy Efficient lighting system is established through LED bulbs.
• Energy Monitoring System (EMS) is in place, for effective utilization of energy.
• Separate parking facility is available near the entrance.
• All the vehicles mandatorily have Emission Test Certificate.
• Plastic-free Campus.
• Usage of one-sided paper is encouraged.
• Total e-governance for Faculty and Student details, library, examination tasks to avoid paper usage.
• Metal and other scraps are given to agents for further processing.
• Separate Dustbins for recyclable and non-recyclable wastes are available in common places.
• Used batteries and electronic wastes are disposed of through outside agencies.
• Various awareness programs like tree plantation, energy conservation etc. are regularly organized.
• Environmental Science is also a mandated course for all the students.

Sources of Energy and Energy Conservation:

An alternative energy source offers the opportunity to engage in initiatives for contributing to environmental protection. The institute is a high tension (HT) consumer with an average consumption of 40,000 units of electricity every month and a contract demand of 250 kVA. The electricity bills stood high while usage of electricity couldn't be compromised on. The concept of a non-conventional energy source owned and operated by the institute seemed a feasible solution.

The alternative energy sources of the institute are made for proper implementation and efficient utilization of renewable energy sources in a systematic way so as to minimize its impact on the environment.

Energy conservation is classified into five broad categories. They are:

• Solar Energy
• Solar Water Heaters
• Biogas Plant
• Sensor Based Energy Conservation
• Use of LED bulbs / Power Efficient Equipment

The institute has taken the following measures for conserving the energy.

1. Solar Energy:

The large magnitude of solar energy available makes it a highly appealing source of electricity. Various efforts have been taken by the institute to utilize the solar energy in an effective way. A rooftop solar power system or rooftop Photovoltaic (PV) has its electricity-generating solar panels mounted on the rooftop of institute buildings.

A 50 kW rooftop solar power panel generates clean electricity, contributing to the college's renewable energy goals. VMTW maintains these panels as part of its green campus policy, certified under ISO 50001 for energy management, to lower operational costs and emissions.

The project was initially conceived as a 250 kW solar power plant to meet all the needs of the institute but received approval for a 50 kW power plant from TSSPDCL (Telangana State Southern Power Distribution Corporation Limited) on technical grounds. The solar power plant can partly take care of the electricity needs of the institute, with the rest being supplied by the electricity board.

2. Rooftop Solar Water Heaters:

VMTW installed rooftop solar water heaters with 35 units, 1120 tubes and 17,500 liters/day capacity to meet hot water needs, reducing fossil fuel reliance.

The solar energy collected during day hours is transformed into electrical energy and stored in the battery for the lighting system during night hours.

The above three solar energy technologies are used in the institution, and for promoting renewable energy usage, various awareness programmes are organized among the faculty and student community.

Highlights:

• Rooftop solar power can meet up to 35% of electricity requirements.
• Diesel for power generation decreases up to 15% of diesel bills.
• Additionally, energy cost is fixed for the next 25 years, unlike diesel / power which keeps increasing.
• Students gain practical, hands-on knowledge of solar plants.

3. Biogas Plant:

A biogas plant is constructed to reduce cylinder consumption. The feed to the plant is the organic waste from leftover and expired food from hostels. The biogas plant has been installed at the back side of the canteen and dining hall for waste management, with a capacity of 02 cubic meters, and also to produce gas which is used as cooking fuel.

4. Sensor Based Energy Conservation:

Automatic water level control sensors are used in overhead water tanks. In the campus, ground water is pumped up to overhead tanks using water pumps controlled by electric motors. The automatic water level controller for overhead tanks switches the pump motor on/off when water in the tank goes below the minimum or above the maximum level. Lighting in toilets and corridors is fitted with automatic sensors — when a person enters, lights are automatically switched ON, and switched OFF automatically when they leave.

5. Use of LED Bulbs / Power Efficient Equipment:

LED bulbs use up to 90% less power compared to incandescent / CFL light bulbs and are highly efficient. LED bulbs are used in various places in the institute for achieving proper lighting. CFL fittings with higher wattage ratings are replaced with LED fittings of lower wattage at the same luminous level in street lights and other possible areas of the campus. Energy Star certified (BEE 3–5 star) products are installed in smart display units (LED televisions) in classrooms, air conditioners, microwaves, refrigerators, ceiling fans and others across the campus.
