Solar India Expo 2022: New Delhi Solar Energy Expo

Rooftop Solar

• The center has envisioned generating 40GW through roof-top grid interactive solar power to fulfill the 100 GW target of solar power.
• Buildings consume approximately 40 percent of the energy produced. By installing rooftop solar, 40,000 MW can be generated by 2022
• Gujarat has seen successful implementation of ‘rent-a-roof solar power program’
• Karnataka benefits from its net metering scheme, consumers receive credits for pumping energy back into the grid
• Textile belt of Coimbatore and Tirupur have begun installing small solar farms on the rooftops of their factories
• NCEF providing 30% subsidy support for implementing Large scale Grid Connected rooftop pilot projects
• For the period upto 2019-20, the government has allocated INR 5,000 Crore (US$ 0.75 billion) for implementation of: 4,200 MW of solar rooftop systems and Grid connected rooftop systems

Ground mounted solar

• The Centre has set an ambitious target of generating 100 GW (1,00000 MW) of solar power by 2021-22 under the National Solar Mission
•  Envisaged to generate 60GW ground mounted grid-connected solar power
• Ground-mounted solar energy systems are very easy to site, because they can be placed on open land. They don’t require drilling into the roof, and the bracing used in standard ground mount systems are lightweight and easy to remove
• A ground-mounted solar array can be more productive per panel than a rooftop solar array. The panels are set at the perfect angle to optimize energy production, which means it can generate more electricity than a comparably sized rooftop system and save money in the long run
• Ground-mounted solar is very easy to access for cleaning and maintenance

Battery Storage

• By 2021, about 11.3 gigawatts of energy storage will be installed globally, equivalent to less than one percent of the total installed capacity of intermittent renewable, according to data from Bloomberg New Energy Finance
• Battery storage to play an important role in India’s sustainable energy future
• With limited investments in research and development of low cost and efficient battery technologies, the cost of batteries remain high resulting in less commercialization, poor adoption of battery storage. Pumped storage hydro power continues to dominate the energy storage in India
• Make in India initiative to manufacture cost effective batteries
• The state-run Solar Energy Corporation of India (SECI) is seeking bids for a 750-megawatt solar park at Ananthapuramu in Andhra Pradesh. In order to supplement the massive series of projects, SECI is looking to procure 100 megawatts of storage capacity
• Over US$ 1.3 billion annual battery storage market in India

Solar Cities

• Development of 60 solar cities and 33 solar parks
• Metros, airports and railway stations implementing solar projects
• Dayal Singh College in Delhi installed solar panels for the electricity requirement of the college and the vicinity
• The CREDA will be setting upto 1KV capacity solar power plant in all govt. schools, panchayat buildings and anganwadis in Chhatisgarh
• In a first of its kind in Central India solar power plant installed on a floating platform at Vidarbha Industries Power Ltd (VIPL), at Butibori, is being seen as a major advance with multiple advantages
• Greater Chennai Corporation will install solar panels on the rooftops of 130 buildings as part of phase-two expansion of the project to tap renewable energy to power the local body’s offices

Smart Villages

• Census 2011 data shows the inequalities in basic amenities between rural and urban India:
  •  While 93% of urban households have electricity, only 55% of rural households have it
  • While 71% of urban households have access to piped water connections, the figure is only 35% for rural households
  • Only 31% of rural households have access to toilets, while 81% of urban households have latrines
• Prime Minister Modi launches mission aimed at turning rural areas into economically, socially and physically sustainable spaces. Launched the Shyama Prasad Mukherji Rurban Mission (SPMRM) aimed at making villages smart and growth centers of the nation.
• Develop around 2,500 Smart Villages by 2019, incorporating solar pumps for irrigation, solar water heaters, solar panels connected with batteries for home lighting and street lighting, etc
• Rurban Mission launched by the Government recently (beginning from a small tribal cluster of Chhattisgarh) aims to bring together 5-7 villages into a cluster with population of 25,000 people. It will be then developed on all fronts like a city with economic standards, electricity, health and education facilities and employment opportunities for locals.
• Odisha government plans to develop 50 MW canal bank solar projects by 2022
• Under Green development initiative two Andhra villages- Toorputallu and Pedhamyanavanilanka will be electrified completely on solar power
• Under DDUGJY-RE, Ministry of Power has sanctioned 921 projects to electrify 1,21,225 un-electrified villages, intensive electrification of 5,92,979 partially electrified villages and provide free electricity connections to 397.45 lakh BPL rural households

Micro Grids

• Micro grid as a concept may be young, but it holds the key to lighting and digitally connecting millions of lives
• The notation of micro grids came from the availability of renewable power and due to demand of electricity from remote areas
•  These are grid-independent self-sufficient grids in remote areas where one uses diesel together with renewable energy to generate power for a targeted population
• A micro grid comprised power generation system, energy storage facility and the load management system. Micro grid of 2-3 MW capacity could cater to 5,000 households

Street Lighting

• The Bureau of Energy Efficiency (BEE) is laying down standards for all stakeholders of street lighting, which involves use of efficient lamp technologies, optimization of pole and placement, efficient light distribution that balances the need for light and visibility
• Solar LED street lighting is an especially cost-effective solution for parking lots, parks, residential streets, airports, and other applications where providing electricity is expensive or problematic
• Solar street lights require much less maintenance compared to conventional street lights.
• UPNEDA (Uttar Pradesh New &Amp; Renewable Energy Development Agency) has set up about 1.25 lakh solar energy based street lighting plants till date under the street lighting program
• Energisation of Street Lights with Solar Power is a State funded scheme of Tamil Nadu under which solar powered street lights were installed in 1,000 Village Panchayats investing a sum of Rs.52.50 crore for energisation of 20,000 street over a period of 5 years from 2011-12

Energy Efficient Products

• Consumer Products: solar water heating systems; Solar home lighting systems; solar lanterns; solar pumps; solar mobile chargers; solar cookers; LED solar torch; solar RO plant; solar fan, solar Inverters, etc.
• Commercial Products: Solar traffic signals; solar road studs/blinkers, etc.

Government Initiatives

• India has added a total of 2,311.88 MW of grid-connected power generation capacity from renewable energy sources like solar and wind this fiscal in the country.
• The Government of India has up-scaled the target of renewable energy capacity to 175 GW by the year 2022. The new target includes 100 GW from solar, 60 GW from wind, 10 GW from bio-power and 5 GW from small hydro-power
• The government has implemented a scheme to install one lakh solar pumps for irrigation and drinking water through State Nodal Agencies and NABARD
• The Government has approved a Scheme for setting up of 25 Solar Parks, each with the capacity of 500 MW and above in next 5 years in various States with Central Government financial support of Rs 4050 crore
• Setting up of over 300 MW of Grid-Connected Solar PV Power Projects by Defence establishments and Para Military Forces with viability gap funding
• Implementation of Scheme for setting up 1000 MW of Grid Connected Solar PV Power projects by CPSUs and GOI organization’s with Viability Gap Funding in three years period from 2015-16 to 2017-18
• The government has set a target of 4,460 MW of power generation capacity addition this fiscal from renewable energy sources, including solar, wind and small-hydro
