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.

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.

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.

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.

Govt eyes 14GWh battery storage system in Kutch.

India plans to set up around 14 gigawatt-hour (GWh) grid-scale battery storage system at the world’s largest renewable energy park at Khavda in Gujarat, Union power and new and renewable energy minister Raj Kumar Singh said at the Mint Energyscape conclave.

This is in addition to a plan to invite bids for the largest global tender for setting up a 13GWh grid-scale battery storage system in Ladakh, as reported by Mint earlier. The strategic push will make India’s grid-scale battery storage programme the largest in the world.

Large battery storages can help keep India’s power grids stable, given electricity is produced intermittently from clean energy sources such as solar and wind. 1GWh (1,000-MWh) of battery capacity is sufficient to power 1 million homes for an hour and around 30,000 electric cars.

“The highest installed storage capacity in the world is a measly 400 megawatt-hour (MWh)," Singh said at the conclave on Friday. “But the first major bid that I am coming out with is 1,000 megawatt-hour—two-and-a-half times the largest capacity in the world. But that also is not sufficient. Only for my national grid-level operations I will need 4,000 megawatt-hour."

The government also plans to call bids for setting up around 4GWh of the grid-scale battery storage system at the regional load dispatch centres. In addition, state-run NTPC Ltd has floated a global tender for setting up a 1GWh grid-scale battery storage system.

“I am going to do it big because 1,000 megawatt-hour is a starter. Ultimately, it will go up to 4,000 megawatt-hour. Then in Leh-Ladakh, I am setting up 10,000MW of renewable energy capacity, so I am adding about 13,000 megawatt-hour of storage there. And then in Khavda again, about 10,000-15,000MW of RE (renewable energy) capacity will come up, so I am going to add another about 13-14,000 megawatt-hour of storage there," Singh said.rding to the government, the Khavda renewable energy park in Kutch will be the world’s largest and will finally generate 30GW of clean energy.

Spread over 72,600 hectares, it will need ₹1.5 trillion investment. The foundation stone of the park was laid by Prime Minister Narendra Modi last December.

The speed, scale, and purpose with which Bharat sarkar is moving on renewable energy is remarkable...! It will not only ensure our energy independence and reduce our greenhouse emissions to very low levels, but also cause tectonic shifts in our relations with other countries. The "koila-tel" gang (OPEC, Russia, China) will increasingly be left in the dust.

Pasting another section of the article here:
Mukesh Ambani’s Reliance Industries Ltd has also announced plans to set up an advanced energy storage Giga factory. India recently unveiled its ₹18,100 crore production linked incentive scheme for developing a battery storage ecosystem that involves setting up 55-GWh manufacturing capacity for advanced chemistry cell batteries.
It seems like Modi will not allow Chinese to bag these tenders. All plans (PLI, domestic capacity building, and tenders) seem well coordinated. RK Singh has been doing excellent work these last few years.

ChemChina unit sells Europe's top solar-panel maker to billionaire Mukesh Ambani's Reliance Industries for US$771 million
SCMP Reporter
Sun, October 10, 2021, 5:30 AM
China's state-controlled chemical giant is selling its entire stake in Europe's biggest solar-panel producer to a company controlled by Asia's richest billionaire, Mukesh Ambani, as the global race to generate clean energy heats up amid efforts to contain carbon emissions.

China National Bluestar Group, a unit of China National Chemical Corp (ChemChina), has agreed to sell Oslo-based REC Solar Holdings to Reliance New Energy Solar, a wholly-owned subsidiary of Indian conglomerate Reliance Industries, at an enterprise value of US$771 million, according to a statement issued by the Mumbai-listed energy group on Sunday.

The purchase will give Reliance a ready global platform and an opportunity to grow in key green energy markets including in the US, Europe and the Asia-Pacific region, the company said in a statement on Sunday.
:
:
The REC acquisition "is in line with our strategy of investing in new and advanced technologies and operating capabilities aimed at achieving Reliance's goal of enabling 100 gigawatt clean and green energy before the end of this decade", Ambani said in the statement.

Reliance plans to use REC's industry leading technology in the Indian firm's fully integrated, metallic-silicon-to-photovoltaic-panel manufacturing facility at Dhirubhai Ambani Green Energy Giga Complex, located in the city of Jamnagar on the western coast of India in the state of Gujarat. This facility's capacity will start at 4GW, before ramping it up to 10GW per annum, according to Reliance.

The conglomerate said it is now ready to set up a global scale integrated photovoltaic giga factory and make India a manufacturing hub for the lowest cost and highest efficiency solar panels.

Holy Kamoli. Reliance really does not do anything small.100 Gigawatt of planned capacity means having the country depending on it for 20% of total power consumption :shock:

On the other hand Gautam Adani had last week mentioned that he wants Adani to be the biggest Green energy player in the world. The competition for biggest and largest bragging rights is going to be a big one and it will be very very interesting duel between India's richest and second richest men.

India’s non-fossil fuel-based capacity meets 40% target under NDC at COP21
“The country’s installed Renewable Energy (RE) capacity today stands at 150.05 GW while its nuclear energy based installed electricity capacity stands at 6.78 GW. This brings the total non-fossil based installed energy capacity to 156.83 GW which is 40.1% of the total installed electricity capacity of 390.8 GW," the statement said.

India recently announced to cut net carbon emissions to zero by 2070 at COP26 in Glasgow.
Installed capacity vs used capacity are different?

Do we not utilize full capacity?

That’s nameplate capacity of power plants by source. Actual power generated is much less. The sun doesn’t shine at night and solar farms produce less power on cloudy/rainy days. Look at energy produced by the Central Electric Authority (CEA). Actual electric energy generated by coal is >72% from CEA data. Solar is picking up peak demand as expected and will remain that way until 2050.

Is anyone knowledgeable about these technologies/materials? Can India do any such breakthroughs?

https://www.cei.washington.edu/educatio ... olar-cell/
PEROVSKITE SOLAR CELL
A perovskite is a material that has the same crystal structure as the mineral calcium titanium oxide, the first-discovered perovskite crystal. Generally, perovskite compounds have a chemical formula ABX3, where ‘A’ and ‘B’ represent cations and X is an anion that bonds to both. A large number of different elements can be combined together to form perovskite structures. Using this compositional flexibility, scientists can design perovskite crystals to have a wide variety of physical, optical, and electrical characteristics. Perovskite crystals are found today in ultrasound machines, memory chips, and now – solar cells.

An accidental discovery could change the world
A lucky discovery could revolutionize the battery and change how we power our world.

On the surface, lithium-sulfur seems to solve all of lithium-ion’s problems. It uses far less ecologically harmful materials, can be cheaper to produce, can be up to three times more energy-dense (meaning a lighter battery) and is far less likely to catch fire. All without compromising charge speeds.

So, what’s the catch? Why don’t we already have them?

Well, they have one huge problem. While a lithium-ion battery can be useable for around 2000 charge cycles, lithium-sulfur is typically limited to around only half that. So, after a year or two of proper use, a lithium-sulfur battery is basically dead
To solve this, the Drexel team was trying new approaches to lithium-sulfur, by changing compounds in the battery’s cathode.

Their goal was to slow down the chemical reaction that creates polysulfides when the battery charges and discharges. These crystals effectively take sulfur out of the electrode and ultimately cause a massive loss of capacity. Slowing them down could make these very energy-dense batteries last longer.


But what they found instead was something incredible: a chemical phase of sulfur that basically stops battery degradation! They were so shocked by this discovery that they had to check 100 times to ensure they weren’t misreading it.

This chemical phase is known as monoclinic gamma-phase sulfur but had only ever been observed in the lab at high temperatures — upwards of 95°C (203°F). This is the first time it has been seen at room temperature.

In the battery, this phase completely stops the reaction that creates polysulfides. This was so effective that the scientists sent the battery through 4,000 charge cycles without a drop in capacity, meaning it lasts at least twice as long as lithium-ion.

It is also worth noting that their battery was three times as energy-dense as lithium-ion and could charge just as fast!
But that isn’t the end of this discovery. The team at Drexel are already looking into using this breakthrough to make sodium-sulfur batteries. By removing the need for lithium, they can make batteries even more eco-friendly and eliminate a massive supply chain bottleneck, ensuring EV adoption can continue at the breakneck speeds carmakers are planning for.

This accidental discovery at Drexel is set to revolutionise the world’s power usage and help humanity transition toward a cleaner, carbon-neutral society. Let’s just hope the team at Drexel can get this technology out of the lab and into our hands soon.

India’s 1st Lithium-Sulfur battery tech introduced for EVs: 3x energy storage capacity & cost-effective
According to the World Economic Forum, a circular battery value chain is a major driver to meet the Paris Agreement, as batteries could enable 30% of the required reductions in carbon emissions in the transport, power sectors.
Shiv Nadar University, research-focused university and an Institution of Eminence (IoE), today introduced Lithium-Sulfur (Li-S) battery technology. The research aims to assist in the production of more cost-effective, safer, more energy-efficient, and environment-friendly Li-S batteries, as a viable alternative to Lithium-ion batteries. The Li-S battery technology employs principles of Green Chemistry, incorporating the usage of by-products from the petroleum industry (Sulfur), agro-waste elements and copolymers such as cardanol (a by-product of cashew nut processing) and eugenol (clove oil) as cathodic materials. This technology can aid industries including electric vehicles, tech gadgets, drones, and more.

The university introduced the tech after research of five years by Associate Professor in the Department of Chemistry, Dr Bimlesh Lochab. According to the research, Li-S battery technology will be significantly cheaper and sustainable, while offering up to three times higher energy density with intrinsic flame-retardant properties.

Very good update:

https://www.weforum.org/agenda/2022/07/ ... en-energy/

Main takeaways from this and other statistics:

Renewables are growing rapidly. In 2021-2022, about 25% electricity generation was from non-fossil sources (renewables + hydro + nuclear).

Renewables installed capacity is now 40% of total capacity. Need to improve the capacity utilization.

Even if India is missing the end-2022 targets by 20% (mainly because of lag in rooftop solar), the scale of this transformation is still massive.

India is creating the domestic manufacturing ecosystem, not just buying imported technology.

India will dump the "koila-tel" era sooner than expected, despite temporary exigencies of energy production using koila.

Awesome. I think Gadkari and Modi are the driving forces behind this. Garkari said at an event that India cannot afford to be oil dependent to ME or other nations for decades to come, we have to break out of that model. Great to see they're going all out.

A very informative article on Solar PV cell and module mfg in India:

Hope Indian industries step up, use PLI schemes and not just produce locally but invest in serious R&D as well to become world leaders some day.

I need to look into Hydrogen energy - so far its been hard to make the H2 generation, storage and usage safe and the cost vs benefit worthwhile. Not sure what significant technology advances have improved the equation. Perhaps solar to electrolyse water to generate H2 ? Will check it out and post anything of interest.

I remain quite skeptical of biofuels/ethanol etc. They will cost too much arable land, water, fertilisers, pesticides and labour and processing that the environmental impact will not be acceptable in the long term.

India’s solar report card for FY 2021-22
India installed 12.3 GW of solar in financial year 20221-22. Of the new additions, 10.1 GW were utility-scale and 2.2 GW rooftop (onsite), according to JMK Research’s Annual India Solar Report Card FY 2022.

The analysts expect the nation to commission 20 GW (16.5 GW utility-scale and 3.5 GW rooftop) of solar in FY 2022-23.

Leading players
In FY 2021-22, overall module sales across the utility-scale, rooftop/onsite, off-grid, and solar pumping segments reached 21,086 MW DC. Chinese manufacturers supplied around 72% of the market demand. Longi Solar was the largest module supplier with a 23.4% share. It was followed by Jinko (22.3%) and Trina (14.8%).

String inverter shipments reached 11.193 MW during FY 2022, with Sungrow (27.9%), Huawei (22.3%), and Solis (12.9%) topping the sales. Central inverter shipments stood at 8,683 MW AC, with Sineng securing the top spot with a 38.4% market share. Sungrow (20%) ranked second and Fimer (19%) third.

Tata Power Solar, Sterling and Wilson Renewable Energy, and Mahindra Susten were the top three EPC contractors for utility-scale solar projects.

Tata Power Solar Systems also topped in rooftop (onsite) PV installations, followed by Fourth Partner Energy and Amplus Solar.

Avaada, ReNew Power, and Fourth Partner Energy were the top three developers that commissioned the maximum capacity in open access projects.
