Integrating Renewable Energy to Grid Viable for India

The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) confirmed the technical and economic viability of integrating renewable energy into a grid with an advanced weather and power system modeling.

The report, titled GREENING THE GRID: Pathways to Integrate 175 Gigawatts of Renewable
Energy into India’s Electric Grid, Vol. I—National Study, says that India’s current power system is dominated with coal but has the flexibility to accommodate the variability associated with the renewable energy targets. Power Poles

“With renewable energy auction prices at record lows, an immense amount of renewable energy growth is anticipated to be added to India’s power system,” principal investigator Jaquelin Cochran, a manager in NREL’s Strategic Energy Analysis Center, said in a statement. “We wanted to provide a systematic way to plan for that. The results of our study can inform policy and regulatory decisions that support system flexibility and renewable energy investment in India.”

According to R&D Magazine, the researchers identified how the Indian power system production cost model is balanced every 15 minutes, the same time frame used by grid operators. This means that 160 GW of solar and wind capacity can serve 22 percent of India’s power demand and the system can manage the added variability of wind and solar without new, fast-ramping infrastructure.

Washington State University Helps Advance India’s Power Grid

Washington State University will lead a nationwide consortium of U.S. universities and industry partners in a five-year, $30 million joint research project with India to advance the development of the power grid in both countries.

The US. Department of Energy  announced a $7.5 million grant to the U.S. team, which will be supplemented by $7.5 million from consortium members. The Indian Ministry of Science and Technology and industry partners will match the $15 million, bringing the total to $30 million.

The U.S.-India collAborative for smart diStribution System wIth STorage (UI-ASSIST) was selected as the new consortia for Smart Grid and Energy Storage under the U.S.-India Joint Clean Energy Research and Development Center (JCERDC).

Led by Washington State University, UI-ASSIST’s American team is comprised of MIT, Texas A&M University, University of Hawaii, Idaho National Laboratory, Lawrence Berkeley National Laboratory, Snohomish County (WA) Public Utility District, Avista, Burns and McDonnell, ETAP Operation Technology, ALSTOM Grid/GE Grid Solutions, Clean Energy Storage, ABB, Philadelphia Industrial Development Corporation, and the National Rural Electric Cooperative Association.

The India team is led by the Indian Institute of Technology (IIT) Kanpur and includes the partners IIIT Delhi, IIT Madras, IIT Roorkee, IIT Bhubaneshwar, and The Energy and Resources Institute, New Delhi, reports T&D World.

Through JCERDC, U.S world-class installations and national laboratories will contribute their expertise and capabilities as India expands energy access to its remote areas, improves its grid reliability and resilience, and strengthens its energy security. In turn, U.S. participants will gain insight from India’s grid modernization efforts – a potential export market for U.S. equipment worth billions of dollars – as well as promote researcher access to India’s grid operational experience.

Russia to Build Two New Nuclear Power Plants in India

India and Russia signed the General Framework Agreement and Credit protocol for Units 5 and 6 of the Kudankulam Nuclear Power plant located in the southern state of Tamil Nadu. Nuclear Power Corporation of India Ltd., and Russia’s Atomstroyexport, a subsidiary of Rosatom, will build the reactors. Each of the two units will have a capacity to produce 1,000 MW of power.

Both countries agreed that there were ‘steady and demonstrable’ achievements in bilateral civil nuclear partnership, including transforming the Kudankulum site into one of India’s largest energy hubs, reports BusinessLine.

PM Modi and President Putin

“We will strive to build an ‘energy bridge’ between our states and expand bilateral relations in all areas of energy cooperation, including nuclear, hydrocarbon, hydroelectric, and renewable energy sources and in improving energy efficiency. Cooperation in the peaceful uses of nuclear energy has emerged as one of the hallmarks of the strategic partnership between the two countries, contributing to India’s energy security and energizing broader scientific and technological cooperation,” said a ‘Vision Document’ issued after the talks.

Microgrids from IIT Madras Win IEEE award

India’s  IIT Madras, bagged the 2017 IEEE Spectrum Technology in the Service of Society Award for “having the most promising potential to provide the greatest overall benefit to humankind.”

IEE’s website mentioned that  micro grids designed at the Indian Institute of Technology Madras can serve as the sole source of electricity to homes not connected to the grid. And they can serve as a backup power supply to homes connected to it, to let lighting and essential appliances continue operating even during brownouts. In India, micro grids are expected to evolve rapidly.

Solar DC Inverterless

The Economic Times reports that the table-sized rooftop plant is a Solar-DC Inverterless system that is cost and energy-efficient. The system is fully equipped with DC wiring, and does not convert direct current produced by a solar installation into alternate current, since each time a unit of AC is converted into DC, there is a 15 percent loss of energy. A DC system is 2.5 times more efficient than the AC system and hence requires lesser space, said IIT-M professor Ashok Jhunjhunwala. The professor added that the solar-DC microgrid will help break the logjam that the domestic power supply currently faces in India.

India’s New Business Opp: Air Conditioners and Power Plants

The Lawrence Berkeley National Laboratory, a specialist in international energy, says that India has four of the five most populous cities with the highest cooling requirements in “cooling degree days,” a measure of the number of degrees above 65º surpassed in a year, and is “poised for an explosion in room air conditioning that may require as many as 300 new electric power plants in the next 10 to 15 years.”

At a seminar hosted by the Stanford Precourt Institute of Energy, Dr. Nikit Abhyankar, a senior scientific engineering associate at the Berkeley Lab who leads the International Energy Studies Group’s work on the Indian power sector, said, “All the cities [in India] are very hot and very populous, which means that going forward, as people get richer, the demand for room air conditioning is going to be increasing.” Abhyankar adds that with the right policy support from the Indian government, India could innovate in manufacturing far more efficient air conditioner models that use refrigerants that do not contribute to global warming.

Forbes reports that air conditioning is expected to double the country’s electricity demand in 15 years, requiring 300 new electric plants just to keep Indians cool. Air conditioning is part of the reason India is expected to be the world’s largest contributor to new electricity demand between now and 2040.
