A new economic viability analysis on Friday revealed that renewable energy along with battery storage in Tamil Nadu is cost competitive with new coal power plants.
The report finds the levelized cost of energy for a hypothetical hybrid, solar, wind and li-ion battery storage system for the state to be Rs 4.97/kWh in 2021, which falls to Rs 3.4/kWh by 2030.

In comparison, cost of electricity produced from new coal power plants in Tamil Nadu is between Rs 4.5-6/kWh.
The hybrid system is designed to cater to 1GW of solar and wind capacity in 2021 with two hours of battery backup, which increases step wise to a four-hour backup by 2030.
The research further highlighted that lithium-based battery storage systems could also help reduce curtailment of renewable energy. Close to 50 per cent of solar power in Tamil Nadu was curtailed since the lockdown in March 2020.
Similarly, its curtailment of wind power in 2019 went up to 3.52hours per day from 1.87 hours per day in 2018.
“Our analysis found that the cost of hybrid RE with battery storage system is at parity with new coal power plants in Tamil Nadu. Moreover, in 10-year time, incremental capacity addition would further drive down the cost by over 31 percent,” said Jyoti Gulia, founder of JMK Research and Analysis.
The analysis, released by Climate Trends and JMK Research and Analytics, tracks the system from an initial capacity of 800 MW of solar and 200 MW of wind along with 500 MWh of storage, that would cater to Tamil Nadu’s average annual power demand for two hours per day from 2021-2023.
Its capacity is augmented to three hours of daily backup for 2024-2026, and then four hours per day for 2027-2030. In the last year, the hybrid system would meet 29 per cent of Tamil Nadu’s average annual power demand at a competitive levelized cost of energy (LCOE) of Rs 3.4/kWh.
It also puts into perspective that Tamil Nadu has five new thermal power projects in its pipeline over the next three years. The Cheyyur ultra mega coal power plant is the biggest of these projects with a tariff of Rs 5-6/kWh, which would be 32 to 43 per cent more expensive than the system modeled in the analysis.
“Tamil Nadu has got the largest installed renewable energy capacity and it leads India’s energy transition efforts, yet it also has the largest coal power pipeline in the country. Since RE with battery storage works out to be cheaper than coal, perhaps TANGEDCO and other state power generation companies need to reconsider the coal pipeline,” Aarti Khosla, Director, Climate Trends, told IANS.
Also, if this hypothetical, solar and wind-powered storage system were to wheel all of its energy to Delhi, even after accounting for interstate transmission system charges it could cover 100 per cent of Delhi’s average yearly electricity demand by 2030 at an LCOE of Rs 4.4/kWh.
“The system thus demonstrates that RE coupled with battery storage is a technically and financially viable option to building new coal capacity. At the same time, it would be a dispatchable source of power that addresses the grid integration of intermittent solar and wind power,” added Jyoti. (IANS)
India is known for its pickles, popularly called 'Achaar', even across the world. But who thought about the idea of pickles in the first place? Apparently, the idea of making pickles first came from the ancient civilisation of Mesopotamia, where archaeologists have found evidence of cucumbers being soaked in vinegar. This was done to preserve it, but the practice has spread all over the world today, that pickles mean so much more than just preserved vegetables.
In India, the idea of pickle has nothing to do with preservation, rather pickle is a side dish that adds flavour and taste to almost anything. In Punjab, parathas are served with pickle; in the south, pickle and curd rice is a household favourite, and in Andhra, it is a staple, eaten with everything. The flavour profile of pickles in each state is naturally different, suited to each cuisine's taste. Pickles are soaked in oil and salt for at least a month, mixed with spices and stored all year round. Mango season is often synonymous with pickle season as a majority of Indians love mango pickle. In the coastal cities, pickles are even made out of fish and prawns.

In other cultures, the pickling process has more to do with preservation. Cold countries, where temperatures drop to very low levels, pickle their vegetables in brine, vinegar, or salt. Sweden is famous for pickled herring, because fishing all year round is hard with all the snow and ice. The German Sauerkraut, originally composed of rice, cabbage, and wine, is now made using salt instead of wine. This gives it a sour flavour that is characteristic of the beloved German delicacy.
In Korea, kimchi is the national delicacy. It is a pickle that is made from pickled cabbages with a distinct mix of spices. Kimchi is made with various core ingredients, and is gaining popularity these days with the Korean Wave hitting the globe. It is a practice that represents the Korean winters, which are too harsh to grow anything. The Kimchi business is one of the largest in Korea, while the individual family recipes are also well-preserved as it is believed that each is unique in its own way.
The pickles made from dill and vinegar are most famous in America. It was introduced to the Americans by the Jewish immigrants. Dill pickles are best paired with sandwiches.

It is impossible to detail the history of bookbinding without understanding the need for it. A very useful, and yet simple invention, spiral coils that hold books together and allow mobile access to the user came about just before WWII, but much before that, paper underwent a massive change in production technique.
Beginning in China, paper was made of bamboo sticks slit open and flattened. In Egypt, papyrus was made from the reeds that grew in the Nile. In India, long, rectangular strips of palm leaves were stitched together to form legible documents. When monasteries were established, scrolls came into being. Parchment paper, or animal hide, also known as vellum, were used to copy out texts periodically to preserve them. Prior to all this, clay tablets were used to record important events, and in some cases, rock edicts were made.
But all this changed with the invention of the printing press by Gutenberg. Paper became the medium by which inscriptions, announcements, and almost everything was made. Once paper became so accessible, printing began in full scale. Newspapers and the Bible were printed every day.

With wads of paper, something had to be done about keeping them together. Bookbinding began as a booming business. First, the pages were just sewn together. A special sewing machine was invented just for books. When this did not suit all book types, the process of punching and binding began. Holes were punched in books, and they were tied together.
Much later, an adhesive thermoplastic strip became available by which book pages were stuck together. They sold in this format for a long time. Ideas began to flow in for notebooks when people discovered that they could attach pieces of paper together. A machine was invented that drew lines. This made it easier for people who wrote a lot.
After a while, when people got used to having their books a certain way, The Spiral Binding Company opened in 1932, which changed the way bookbinding was done. Books could now be bound by coil and this was not only economical, but also convenient, because pages could easily be turned without breaking the bind. The original spiral bind coil was made of metal, but when supplies were rationed during WWII, they were made from plastic. This trend has remained to the present day, where spiral bound books are preferred to the other kinds of binding except in cases of publishing and official documentation.
