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.

Think-EverStream JV bags KREDL’s solar tender

download 3707/02/2018

Think Energy, a New Jersey-based solar development company and EverStream Capital, a renewable energy focused PE fund manager, have formed a partnership to capitalize on entering Karnataka’s solar PV market.

The Think- EverStream Joint Venture in Karnataka is planning to tap both ground-mounted and rooftop PV assets with commercial and industrial off-takers, as well as select State and Central government utility-scale tenders.

Both the companies under partnership with a Spanish developer have developed, financed, and built a 100 MW portfolio of utility-scale solar projects in Telangana. The six projects were successfully commissioned in fourth quarters of 2017 and are commercially operational.

The joint venture company bagged few the Solar Energy Corporation of India’s (SECI) roof-top tenders totaling 23.39 MW, which will be located in the states of Karnataka, Maharashtra, Gujarat and Andhra Pradesh.

“The company recently won Karnataka Renewable Energy Development Ltd’s (KREDL) 55 MW of solar capacity tender. Building on this success, the JV plans to develop or acquire over 2,000 MW of solar projects throughout India over the next three years and expects to invest upwards of $300 million in equity capital,” said Ravishankar Tumuluri, MD of the Think – EverStream Joint Venture Development Company.

Tamil Nadu should double its wind energy capacity to 15 gigawatts (GW) and increase its solar capacity six-fold to 13.8 GW by 2026-27 whilst simultaneously delivering cheaper electricity, the Institute for Energy Economics and Financial Analysis (IEEFA) said on Wednesday.

An IEEFA's report, "Electricity Transformation in India: A Case Study of Tamil Nadu", showed how Tamil Nadu is building 22,500 MW of expensive coal-fired power plants -- almost double the entire existing coal-fired fleet in the state -- despite the favourable investment and electricity tariff costs of wind and solar.

It warned that building more non-pithead coal-based plants at a time when existing plants are being used at a low 62 per cent of the time, as opposed to the optimal 80 per cent, will make new and existing plants financially unviable.

The IEEFA's research and modelling predicts that many new coal-based plant proposals such as the 4,000 MW Cheyyur ultra mega power project will be cancelled due to unfavourable financial factors.

A more diversified electricity generation mix will best serve Tamil Nadu, IEEFA's Energy Finance Studies Australasia Director Tim Buckley said.

He said new lower cost solar capital additions and a major repowering of Tamil Nadu's wind projects, a concerted improvement in energy efficiency plus reduced transmission and distribution losses, should deliver more than 80 per cent of all electricity demand growth over the coming decade while also driving wholesale price deflation.

This investment program would also underpin the attempts of Tamil Nadu's power utility to operate profitably, something it has not been able to achieve for more than two decades whilst having a positive impact for the state's consumers.

Buckley told that "Despite being a world leader in wind energy, Tamil Nadu's wind farms are operating with aging and outdated technology. Upgrading or 'repowering' existing turbines alone could double the state's leading wind energy capacity".

The IEEFA expects offshore wind to emerge as a new, cost competitive source of electricity generation.

The report highlights that any investment in new coal and nuclear based projects could cause further financial distress to any firm involved.

"This is a clearly identifiable and recurring trend no matter which market or company we research across the globe," Buckley said.

Tamil Nadu already operates the most diversified electricity generation fleet in India, with renewables representing 35 per cent of installed capacity as on March 2017, contributing to one fifth of India's total renewables generation.

Hydro represents another seven per cent of the total capacity.

Tamil Nadu's power utility, Tamil Nadu Generation and Distribution Corporation Limited (TANGEDCO), reported a staggering loss of Rs 13,985 crore in 2013-14.

Subsequent reforms under UDAY scheme have helped TANGEDCO not only reduce its losses to Rs 3,783 crore in 2016-17 but also reduced its deficit on energy availability from 12.3 per cent in 2011-12 to a record low of 0.6 per cent in 2015-16.

The IEEFA expects a break-even result for TANGEDCO in the next fiscal and the utility then moving to net profit for the first time in two decades.

Tamil Nadu is in pole position to be the national powerhouse in India and indeed the region for low cost, sustainable energy, added the report.

India has set ambitious plans to diversify its electricity production into zero-emissions, lower cost alternatives at the same time as it doubles installed capacity over the coming decade.

The 2016-17 year was a transformational one for India. Compared to the previous four years, thermal power installations dropped by 60 per cent to just eight GW of the net new capacity, while renewable energy installations more than doubled to a record 15.7 GW.

These trends have continued in 2017-18.

The Maharashtra Electricity Regulatory Commission (MERC) has approved Nagpur Municipal Corporation's (NMC) waste-to-energy plant, and also accorded it 'Must-Run' power plant status. All decks have now been cleared for execution and smooth running of the project planned three years ago.

MERC passed an order on the petition filed by NMC's private operator — Nagpur Solid Waste Processing and Management Private Ltd (NSWPMPL) — on Monday. NSWPMPL is a company incorporated by Essel Infraprojects Limited and Hitachi Zosan India Private Ltd.

With the MERC order, Maharashtra State Electricity Distribution Company Limited (MSEDCL) will purchase 11.50MW power to be generated at the plant. As it is a renewable energy project, MERC has fixed power purchase rate at Rs7 per unit, which is almost double the gross power purchase rate of MSEDCL, which is Rs3.90 per unit. Since it was accorded 'Must Run' power plant status, MSEDCL will have to continue purchasing power from the plant even if demand is low.

Municipal commissioner Ashwin Mudgal said tariff of Rs7 per unit and 'Must Run' status will ensure success of the project. "Garbage disposal is a major issue. We will be generating power from garbage. Thus, issue of garbage disposal will be solved and ensure wealth from waste. Therefore, plant has been given 'Must Run' status," he said.

Around 1,100 tonne garbage is generated from the city daily. About 200 tonne garbage is being treated at the plant operated by NMC's private operator Hanjer Biotech. At the waste to energy project, 800 tonne garbage will be treated. Thus, 1,000 tonne garbage will be disposed off in scientific manner. There is also scope to increase capacity by 20% in the project.

NSWPMPL will develop the project by investing Rs218.80 crore. NMC will give Rs70 crore to NSWPMPL as viability gap funding for execution under Swachh Bharat Mission. NSWPMPL will develop the project in two years followed by operation and maintenance for 15 years. NMC will pay tipping charges of Rs225 per tonne, which will increase by 4.5% every year. NSWPMPL will get revenue from MSEDCL for purchase of power and recover its investment.

NSWPMPL will also operate existing landfill site and develop two more, including their operation and maintenance for 15 years. This will ensure mitigation of fire incidents, foul smell, pollution in groundwater and air.

The Punjab's leading business association -- Chamber of Industrial and Commercial Undertakings (CICU) -- is working on a plan to use solar energy to replace the conventional heating systems in factories belonging to its members.

CICU members Tuesday held a meeting with the United Nations Industrial Development Organisation (UNIDO) and discussed the feasibility of this project.

CICU president Upkar Singh Ahuja said, "Several industrial processes require heating. These equipment are highly expensive and heating methods add to the running cost. In view of these factors, solar power is the best bet for the industry as it has low running cost and is completely nonhazardous."

"UNIDO, which works for the industry in different areas, will now help us get financial help from government bodies for the implementation of solar-powered heating systems in our factories. It will prove useful in high temperature applications and other applications including steam production, thermic fluid heating, air conditioning and incineration," Ahuja added.

The CICU president said, "Once we are through with all the formalities and have a plan of action, we will ensure that the majority of our members make use of this environment-friendly technique and cut expenditures."

Dr Anil Misra, national project manager, UNIDO, addressed the industrialists and informed that UNIDO has teamed up with Indian Renewable Energy Development Agency (IREDA) to develop a financial package including the subsidy from the Union ministry of new and renewable energy and soft loan to support the installation of projects for industrial applications of heating and cooling.

Other members present in the meeting included Padam Kumar Aul, S B Singh, Ram Lubhaya, Shiv Kumar, Rajesh Kumar, Sukhmeet Singh, S N Tiwari, Deepak Sharma, Ashwani Goyal, S K Soni, Jaswinder Singh, Hem Raj Mehta and Inderpal Singh.

After a long gap, things seem to be moving in Hubballi Dharwad Municipal Corporation concerning the setting up of a waste to energy plant to process the solid waste generated in the twin cities to convert it into energy.

On Monday, the municipal corporation signed a Memorandum of Understanding (MoU) with IDECK, Bengaluru, for preparing the feasibility report on setting up the waste to energy plant.

Municipal Commissioner Major Siddalingayya Hiremath and vice-president of IDECK Manjunath Shekhar signed the MoU on preparing the feasibility report in a simple ceremony held at the municipal commissioner’s office here on Monday.

In the municipal corporation limits, an estimated 400 tonnes of solid waste are generated daily and it is proposed to generate power by burning the unsegregated wet and dry waste through inceneration technology.

Under the plan it is also proposed to get extra revenue for the municipal corporation through the sale of power, thus generated.

The MoU follows the approval given by the State Finance Department to get consultancy service from IDECK in Mysuru and Hubballi for setting up “waste to energy plants by clustering Urban Local Bodies”.

After the Finance Department’s approval the Department of Urban Development had given approval for hiring the services of IDECK at a cost of Rs. 49.98 lakh for preparing the feasibility analysis.

As per the MoU, IDECK will get six weeks to conduct a study and submit the feasibility analysis to the municipal corporation on the waste to energy project.

Although the waste to energy project was envisaged in Hubballi Dharwad several years ago, the project did not materialise due to several technical and administrative reasons.

The municipal corporation has earned the wrath of the residents, as a full fledged waste management system is yet to be put in place in the twin cities.
