    Dr. R. Velraj, Director of the institute of energy studies, Anna University, said the solar sector cannot grow without adequate manpower. “University courses and curriculum do not meet the specific skill requirement of the renewable energy industry. The curriculum must focus on technology and design. Also, the institutions should provide extensive training and exposure on latest trends and technologies,” he said.

    The professor said Anna University was the first university in the country to start M.E. Solar Energy programme in 2010. Across the country, over 50 institutes are offering master level programme on Solar and about 1,000 students are benefiting, he said, pointing to the shortage of skilled ITI-trained candidates who have exposure to renewable energy. “The syllabus of ITI needs to be revisited to strengthen and build awareness on RE,” he said.

    “We have partnered with TEDA and private companies to hold training programmes for academicians, engineers and technicians. On this experience, we are planning to train trainers in the next one year,” he said. Anna University has been identified as one of the partners for solar energy training network which plans to train 4.25 Lakh qualified and skilled manpower in solar energy sector, he said. A senior TEDA official said manpower requirement for setting up solar plant, utility or rooftop is largely a combination of fabrication, electrical and masonry skills.

    “For ITI students with electrical background, the skill up-gradation needed is minimal and can be through on-the-job training. However, at project management level, there is a growing need for qualified manpower as it requires specialized knowledge and training,” he added.

  • New Indian Express, India – 24th October, 2016 on his Research Project (

    To overcome power challenges faced by the rural population, the Anna University (AU) is leading a research project, where villages can completely switch over to renewable sources of energy without any power cuts or disruptions. Joining hands with AU are Madras University, Alagappa University and Bharathidasan University. Shortly, there would be a technology demonstration in one of the villages in the State, said Director of the Institute of Energy Studies R Velraj, who is also the principal investigator of the project. The project focuses on generating cool energy that will be stored. The source of power would be solar and wind energy. Besides electrifying homes and offices, the energy generated can be used to preserve dairy and food products in villages where air-conditioning facilities are inadequate. The official said that in recent years there was a boom for renewable energy, but solar and wind energy are intermittent. There is a mismatch between demand and supply.

    “There is a need for energy storage and if we can promote decentralized power resources in village side, it would help both in job opportunities and industrial activities,” he said. Velraj said in order to overcome the present energy challenges, smart technological solutions are the need of the hour. A project titled “Sustainable energy technologies- efficient renewable power generation with energy storage for sustainable smart grid” was submitted to the Ministry of Human Resources Department (MHRD) under research and innovation scheme in December last year. The Project Approval Board (PAB) of MHRD has sanctioned a grant of `15 Crore. The project is in line with Providing Urban Amenities to Rural Areas (PURA) and Tamil Nadu’s strategic plan for infrastructure development for greener tomorrow. “The major objective of this project is to maximise the share of renewable energy (solar, wind, bio energy) in total power generation and reduce the barriers in the integration of new storage technologies,” he said. Small villages can generate locally 0.5 MW to 5 MW, Velraj said. This can be further fed into the grid. Power can be generated in the open terrace. Explaining the micro grid concept, he said, “This project is focusing on generating power in villages so that micro grid concept can be adapted. We can generate power from solar and wind and this can be transferred to all houses and offices of the villages through the local transmission line called micro grid. Thereby we can introduce energy storage concept and be independent of TANGEDCO. ”To a query, Velraj said they are yet to identify the village, where the technology will be adopted and demonstrated. He said the first instalment of `7.5 crore had already been allotted out of the total `15 crore for this research project.

    CHENNAI: Several colleges are increasing their installation capacity of solar power plants to cut down on the electricity bills. Already, many educational institutions have units generating 20 Kilo Watt (KW) to 100 KW, and now they are going to 500 KW units. Institutions like Anna University (AU), Madras Medical College (MCC), MOP Vaishnav College, D G Vaishnav College, Vivekananda College, Jerusalem Engineering College, and Mohammad Sathak AJ College of Engineering on OMR are using solar power. Anna University installed small-capacity solar power generation plant in 2013. Currently, the three colleges affiliated to the AU, including College of Engineering, Guindy, Madras Institute of Technology (MIT) and AC Tech, generate 34 KW daily. The CEG alone generates 20 KW bringing down the combined electricity bill by Rs 30,000 per month in these institutions, said R Velraj, Director, Institute for Energy Studies. Now, the AU took a decision to go for bigger solar power plants. The university is going to install large power plants in the College of Engineering, Guindy, which will generate 500 KW solar power. “While large solar power plant will be installed in CEG, Rs 1 Crore is allotted for solar streetlight, sanctioned by the MHRD, of which half will be installed in CEG and half in MIT,” he said. He also added that under another Tamil Nadu Govt scheme, 100 KW solar installation will be done in MIT and 150 KW in AC Tech. Under the same scheme 18 colleges under Anna University will have 50 KW solar power plant, which is also approved by the government.

    With concern for non-availability of potable drinking water growing, researchers at Anna University have come up with a smart solution to address the issue using domestic goods like a refrigerator and air conditioner. They claim that drinking water can be produced using heat from solar Photovoltaic (PV) operated Vapor Compression Refrigeration (VCR) system or AC following the simple logic of evaporation and condensation. R Velraj, Director, Institute for Energy Studies, Anna University, said the heat that is pumped out to the atmosphere by the evaporator in one tonne AC machine can be utilized to generate 20 litres of water per day. Velraj and his team submitted the project proposal titled ‘Desalination through ,nhhhwaste heat recovery from solar PV operated VCR system’ to the Department of Science and Technology and a grant of ` 35 lakh has been provided for the project .
