To reduce dependency on conventional sources of energy, rooftop solar panels have been installed at Mysuru railway station platforms and division office. The ongoing work is scheduled to be completed by February 15.

Divisional Railway Manager, Atul Gupta says, "Under the green energy programme, the station platform and building will be used to generate 210kWP of solar energy, 100kWP from divisional office and remaining 110kWP from railway platforms. Since we don't have back-up facility, we may not able use the solar power during night hours. This will, however, help to cut down nearly 30% of cost spent on electricity. The project was taken up on Design, Build, Finance, Operate and Transfer (DBFOT) basis. The investment has been made by a private player, we will buy power for a period of 25 years under a power purchase agreement. After 25 years, the solar power system will be transferred to the railways."

Mysuru Central Railway Workshop at Ashokapuram is already generating 500kWP solar energy after having installed solar roof top system in December.

In 2015, Indian Railways had drawn a road map to reduce the use of conventional energy and planned to tap non-conventional energy in a phased manner to reduce carbon emission and improve the financial performance of railways.

Renewable energy firm Siemens Gamesa said it has bagged 160MW of solar EPC orders from two customers from Tamil Nadu and Karnataka, respectively.

The company will provide complete turnkey solutions including infrastructure, engineering and design of solar farm, erection and commissioning of photo-voltaic solar farms in Tamil Nadu and Karnataka as per the agreement.

The projects are slated for commissioning in March 2018, a company statement said.

"Today India is one of the most promising markets for renewable energy. The country has witnessed incremental growth in solar segment in last three years and we expect the momentum to increase in coming years," Siemens Gamesa India, CMD, Ramesh Kymal said.

"Having firmed up our roots in solar business, we are fully geared to contribute to the government's target of 100GW of solar power by 2022," he added.

A document issued by Coal India says, renewable energy will start replacing coal-fired power as solar tariffs are poised to fall below Rs 2 per unit in seven years and storage costs fall, while cheaper international supply can lead to imports of 20 million tonnes, posing a big challenge to domestic suppliers.

The competitiveness of domestic supplies will be a challenge as costs such as wages rise, according to the document prepared with the help of a consultant hired by the monopoly to assess the future of coal in the era of plunging renewable energy costs and rising concerns about polluting fossil fuels such as coal.

The report, on which Coal India is seeking public comments, says that unless costly mines are retired and prices of coal corrected downwards, domestic supply may remain stagnant or even fall.

South Central Railway (SCR) became the first railway zone to have total 100% LED lighting in all its 733 stations with 75,681 conventional lights of different wattages replaced in divisions of Secunderabad -162, Hyderabad -100, Vijayawada -158, Guntakal -157, Guntur -76 and Nanded -80.

This is expected to save a total 32 lakh units of electrical energy and an amount of ₹270 lakh per year.

GM Vinod Kumar Yadav complimented officers and staff for the achievement, a release said.

The school of bio-energy and farm waste management of Kerala Veterinary and Animal Sciences University (KVASU) has developed a biogas plant which, it claims, is more efficient in converting kitchen waste into biogas.

The restricted flow anaerobic baffled reactor biogas plant is modelled on cow’s digestive system.

“The plant has a digester with a capacity of 3,000 litres, a balloon gas holder, moisture remover, and carbon dioxide and hydrogen sulphide removers,” John Abraham, Assistant Professor at the school, said.

“The first chamber of the digester unit will be filled with stomach content (rumen) of cattle collected from abattoirs and the second chamber will be filled with cow dung for producing microbes. Later, kitchen waste can be fed into the digester as feedstock for the microbes and it starts to produce biogas anaerobically,” Dr. Abraham, who mentored the project, said.

He said a major advantage of the unit was that biogas generated at the unit could be transported in a specially made balloon.

Moreover, commercial type of burner could be used with it by the help of a biogas compressor.

The digester has vertical baffles which restrict the flow of kitchen waste, which aids multiplication of microbes. “In traditional biogas plants, the hydraulic retention time or the time for completing digestion of the feeding material is high. But the retention time in the new plant is low as it has two chambers,” Dr. Abraham said.

Around 100 litres of kitchen waste could be fed daily into the plant that produces 2 cubic metres of biogas a day. The project was completed in six months expending ₹1.50 lakh.

As the government continues to focus on increasing renewable energy capacity, solar and wind power tariffs are likely to dip below Rs 2 per unit in the next 2-3 years, a senior official of transmission firm Sterlite Power said.

Sterlite Power CEO of global infrastructure business Ved Tiwari told that "Solar power has already reached Rs 2.4 per unit, while wind is selling at Rs 2.50 per unit. This will continue to go down...below Rs 2 in the next 2-3 years".

The solar power tariff fell to an all-time low of Rs 2.44 per unit during the auction of 500 MW of capacity at Bhadla (III) in Rajasthan. The government had offered viability gap funding (VGF) for the project.

"During 2017, solar power tariff hovered around Rs 2.40 per unit only in auctions for capacities, where viability gap funding component was there," Tiwari said.

Wind power tariff, on the other hand, dropped sharply to Rs 2.43 per unit during an auction conducted by Gujarat Urja Vikas Nigam Ltd (GUVNL) last year.

Tiwari further said with abundant solar and wind potential, southern states like Andhra Pradesh, Telangana, Tamil Nadu and Karnataka, have the opportunity to become exporters of power.

"Earlier, power used to be transported to states like Tamil Nadu and Andhra Pradesh and Telangana. But this situation has now changed. States like Telangana, Karnataka, Tamil Nadu, Andhra Pradesh are blessed with best of solar radiation and wind energy. These states will become exporters of power," he said.

However, he emphasised on the need for enhancing transmission network saying that the economic power can be unleashed for these states if India invests in power transmission.

"Just like India builds highways and roads that unleashes economic potential, much more economic potential may be created by power transmission lines. The country should build more and more power corridors, which would enable states to freely exchange very cheap electricity," Tiwari added.
