Saw somewhere a plan to cover major irrigation canals with solar panels killing 2 birds with one stone.

Conserve water by reducing evaporation losses + No need for land acquisition hence lower cost and reduced ecological impact.

Its a promising idea and many areas in India would be suitable.

We need some real innovations in this area to make solar power affordable and sustainable.

This has been done in places like Gujrat. Also they are building floting plants on lakes. Perhaps covering the highway could also be considered. Would provide shade and maybe also save the vehicles and tarmac from the heat.

I don't think the poster "Mort walker" is a oil-gas "lobbyist", simply because oil-gas lobbyists are far more sophisticated.

Some of the canals from the sardar sarovar dam are covered with solar panels. You can spot them when you move around Vadodara

Trust what the Central Electricity Authority (CEA) is saying and see what is happening to Discoms across India. Energy consumption has slowed until there is further growth in the economy. The GoI no longer has more money to bail out the Discoms further. There are no power systems engineers contributing in these threads, nor anyone who works in power distribution systems. Instead we get links to dubious studies and "trust Modi" instead of real numbers. Rooftop solar and unique applications are a great thing, but large scale industrial production is altogether different. Lots of hype on large scale solar, but the energy produced is not there.

Installed capacity of solar as of July 2020 is 35.303 GW.

There has not been ANY discussion on the 2020 Draft Electricity Bill with regard to solar or any other energy source in this forum. This bill modifies the 2003 Electricity Act.

https://www.pv-tech.org/news/india-turns-to-renewables-to-replace-retiring-coal-power-plants

Speaking at the virtual India PV Edge 2020 event, power minister R. K. Singh said 29 coal plants are set to be decommissioned, with the space to be occupied by renewable generation.

.....

With India estimated to import 80% of the components used in solar developments from China, its government is now aiming to stimulate domestic solar equipment manufacturing through new production hubs near major ports, while reports this week suggested state-owned companies could be instructed to establish a polysilicon supply chain in the country.

AmberG,

Not a single person on that panel is a professor of electrical engineering or power systems engineering. Not a single person who is an IEEE Fellow in Power & Energy Society or Power Electronics Society. There are several Indians in these relevant professional societies. I would also add there is not a single physicist in the panelists either.

This appears to be more of a discussion on alternate fuels.

Explained: What is India’s sprawling renewable energy park, coming up on its border with Pakistan?

On December 15, Prime Minister Narendra Modi will travel to Kutch to lay the foundation stone for a 30,000 MW (megawatt) hybrid renewable energy park close to the Indo-Pak border in Kutch district. The project is billed as the largest of its kind in the world.

What is this hybrid renewable energy park taking shape in Gujarat?
With the Government of India committing itself to installing 175 GW of renewable energy capacity by 2022, the Gujarat government identified 1,00,000 hectares of wasteland near Khavda, 72 km north of Bhuj, close to the international border with Pakistan in Kutch, for an energy park.

In April 2020, after taking into consideration the requirements of the defence forces, the Ministry of Defence (MoD) gave its approval to use 72,600 hectares of the identified land to build the park.

The renewable energy park will have two zones: one, a 49,600-hectare hybrid park zone that will accommodate wind and solar power plants of 24,800 MW capacity; and two, an exclusive wind park zone spread over 23,000 hectares.

How close is this project to the Indo-Pak border?
The project will be located between Khavda village and Vighakot. The project site is about 25 km from Khavda, which is the last point that can be accessed by civilians in the area.

The exclusive wind park zone will come up within 1-6 km of the international border. The hybrid park zone will be located 6 km from the border. The Border Security Force is already present in the area.

“This site has been chosen because this is a complete wasteland. (At last some common sense being utilized in using wasteland) Secondly, if you put windmills near the border, they also act as a boundary. :?: The MoD gave clearance for 72,600 hectares in April this year,” Sunaina Tomar, additional chief secretary, Energy and Petrochemicals Department, Gujarat, said.

Who will set up the wind and solar projects in this park?
The state government, after inviting applications, has allocated land to six developers. For the hybrid park zone, land has been allotted to Adani Green Energy Ltd (19,000 ha), Sarjan Realities Ltd (Suzlon, 9,500 ha), NTPC Ltd (9,500 ha), Gujarat Industries Power Company Ltd (4,750 ha) and Gujarat State Electricity Corporation (6,650 ha).

Adani Green will install capacity of 9,500 MW; Sarjan Realities, 4,750 MW; GIPCL, 2,375 MW; GSECL, 3,325 MW; and NTPC, 4,750 MW.

The entire 23,000 ha at the exclusive wind zone park has been allotted to Solar Energy Corporation of India (SECI) to set up wind projects under the competitive bidding route policy. “The selected developers have to develop 50 per cent of the total generation capacity in the next three years, and finish the project in five years,” Tomar said. PowerGrid Corporation of India will evacuate the power produced at this park.

How will construction take place in a zone that has BSF and Army installations?
The BSF and Army installations are beyond the India bridge manned by the BSF. “An 18-km road will be built by the state public works department. It will bypass India bridge and provide access to the project. Also, the existing road that leads from India bridge to Vighakot is being strengthened and widened,” a state government official said.

There is a number of “no-go zones” around the project that belong to either the Army or the BSF.

What is the current renewable energy capacity of Gujarat?
The current peak power requirement of Gujarat is 18,000 MW. Out of the state’s installed power generation capacity of 30,500 MW, renewable energy forms 37 per cent or 11,264 MW. This includes 7,845 MW of wind, 3,273 MW of solar, 81.6 MW biomass, and 63.33 MW mini-hydro projects.
There has been a 10-fold increase in renewable energy capacity from 1,170 MW in 2008 to 11,264 MW in 2020.

Sharing a writeup by Dr Karandikar of IIT Kanpur. Congrats to Ministry of Education etc and IIT's to start this new branch..
I am delighted to share that in a landmark and historic decision, BoG of IIT Kanpur (on the recommendations of the Academic Senate) has approved establishing the Department of Sustainable Energy Engineering (DSEE) with the aim of becoming a vital contributor to nation’s growing clean and renewable energy sector by generating high quality scientific & technological know-how and human resources.
The vision of the new department is to contribute to India’s bid to become a global leader in the widespread adoption of sustainable energy technologies impacting a variety of sectors such as electricity & transportation.
It plans to offer high-quality academic programmes at both the undergraduate and graduate levels, to provide multiple skill-sets to its students, with relevant courses from core engineering disciplines blended with science and humanities. The curriculum will train the students to become well-rounded energy engineers who will become assets to the industry as well as academia and research organizations. Through this and more such efforts IIT Kanpur plans to add its bit in #NEP2020 by offering multi-disciplinary courses in technical education.
My Special thanks to Dr Radhakrishnan K Koppillil (Chairman, BoG, IIT Kanpur) for his continued support to this initiative and Prof Ashish Garg for leading this initiative.

Silicon Photovoltaic Module Manufacturing Costs and Sustainable Pricing
NREL document on Solar Photo Voltaic (SPV) Analysis. Its very good. India has module manufacturing infra., but not wafer and cell ecosystem. This document suggests we shall invest in Silicon (Si) crystal manufacturing that caters to electronic grade and monocrystaline SPV. A few B$ investment could kick start a huge ecosystem.

GoI's current approach is to install small turnkey based SPV electricity generation by different government organizations.
The recent tender of 5000 Crore INR (only large tender) alloted to Adhani may end up as a polycrystalline Si pllant, which will not cater to electronic grade Si manufacturing.
Current gen. of polycrystalline Si gives cell level efficiency ~12% and monocrystaline is ~ 23%
China is not allowing installation of polycrystalline any more and exporting them out huge and cheap volume around the world. These polycrystalline panels will become a huge headache in few years. With monocrystaline Si, especially in sunny country like ours, the return on energy invested (RoEI) will be worth the increased cost of monocrystaline Si wafers.

GoI shall allow installation of only monocrystal SPV and encourage government iinstitutions to place order to one or two Indian vendors, who may be encouraged to invest monocrystal Si boule and wafer making infrastructure, which can also cater to electronic as well as SPV industry.
