adminIndia has always been a country of dichotomies.
It is the world’s most populous nation, fifth biggest economy and home to the highest number of billionaires after China and the U.S. It is a world leader in digital finance, thanks to the creation of digital public infrastructure, and is the world’s third-largest start-up hub.
Yet it remains a lower-middle-income economy, with a large share of the population classified as low-income or poor, and is a highly unequal society.
India’s climate narrative is, similarly, marked by contradictions.
While its contribution to world cumulative emissions is negligible — India accounts for approximately 4% of the global stock of emissions in the atmosphere — and it is one of the lowest emitters on a per-capita basis, India is already the third-largest emitter of greenhouse gasses on an annual basis, and is, worryingly, home to 12 of the world’s 15 most polluted cities.

With India forecast to be the world’s fastest-growing large economy and biggest oil consumer over the coming years, if it does not take action fast, emissions will only continue to rise.
‘Greening’ of the power sector
India needs to act not only for the world to achieve the Paris Agreement ambitions, but also for its own survival.
More than 75% of Indian districts are at risk of extreme weather and it is already seeing fiercer cyclones, greater incidences of drought and flooding and more heatwaves. While these climatic changes will impact worker productivity and economic output in aggregate, they will disproportionately impact vulnerable communities and farmers — 60% of which are monsoon-dependent.
While India needs to decarbonize its entire economy, achieving its target of net-zero emissions by 2070 arguably hinges on the “greening” of its power sector.
With a 34% share, India’s power industry constitutes the single biggest source of emissions in India, and its grid ranks as the fourth most carbon-intensive in the world. Coal still accounts for almost 50% of installed power capacity, and more than 70% of power generation.
With greater power demand expected from consumers, as well as existing and emerging areas of industry, in the near future, and the ongoing electrification of the economy also putting greater pressure on the grid, emissions from power will continue to rise if left unabated.

In recognition of the imperative to decarbonize power as a means to drive the whole-economy emissions transition, the government has outlined impressive clean energy targets: achieving a 50% share of renewables in power capacity by 2030 and energy independence by 2047.
India has made impressive strides toward these goals. As a result of significant private sector investment, India now ranks fourth of all countries globally on installed solar and wind power capacity and its addition of renewable power capacity has been particularly strong in recent years.
Unfortunately, this simply isn’t enough. To truly decarbonize its energy sector, India needs to act on three fronts.
1. Integrating renewable energy into the grid
Apart from greater renewable capacity installation — for context, India’s additions in 2024 represented only 8% of China’s — India needs to find ways to integrate greater amounts of renewable energy into its grid, a challenge that countries globally are grappling with, while continuing to invest in baseload (or round-the-clock readily available) power.
To do this, India needs to invest more in battery storage infrastructure — including via pumped hydro storage, new and innovative battery energy storage systems, and also green hydrogen.

Indeed, the inability to transmit renewable energy into the grid when it is generated in surplus (for example, solar during summer months in south-western states) often leads to curtailment, or the intentional offloading of power production, as the lack of storage capacity prevents its use in power-scarce states.
Digitalization of the grid will also be key to integrating renewables. Emerging digital technologies can enable power operators to access information from renewable energy assets and consumers in real time, allowing them to operate intelligent load-dispatching systems based on current supply and demand.
In order to have a tangible impact on renewable power integration, grid digitalization will need to take place concurrently with electricity market reform.
Currently, India’s state electricity distribution companies, or DISCOMs, have limited flexibility in incorporating renewables as per availability and demand as they are locked into long-term power purchase agreements (PPAs).
Plans for what’s known as a Market-Based Economic Dispatch System, which would centralize power purchase and dispatch across the country on a real-time basis, will enable India to transition from relatively inflexible locked-in power agreements with thermal power producers to lowest-cost (including renewable) generation.

A digital energy grid overlaid with centralized power purchase and dispatch will improve efficiency in power trading, and also likely lead to lower power prices.
While this transition takes place, greater flexibility is needed at India’s coal power plants to ensure a steady baseload supply of power, while more investment in nuclear is needed to guarantee future energy security. Reassuringly, India has already outlined plans for both.
2. Improving energy efficiency
The second front constitutes a greater focus on enhancing energy efficiency, both on the demand and supply side.
On the demand side, smart appliances, buildings, and meters, coupled with time-of-day tariffs, can enable better demand optimization. On the supply side, meanwhile, the professionalization of state distribution companies via arrangements with private operators can be instrumental in reducing transmission losses.
India sees heavy losses in power transmission across most states as infrastructure remains outdated, while leakages and theft are rampant.
Indian residential and agricultural consumers have long thought of electricity as a free public good, and for good reason. India’s DISCOMs heavily subsidize power to these two segments.
Professionalization of power distribution can help lower these subsidies and reduce wastage. States that have professionalized distribution have indeed shown a significant reduction in transmission and distribution losses. In a power-hungry — power demand is expected to quadruple by 2050 — and historically power-scarce country, there is no room for waste.
3. Decentralized energy solutions
The third front constitutes the greater installation and use of decentralized renewable energy (DRE) solutions, including rooftop solar and microgrids.
This will enable India to meet the dual goals of both improving power access for India’s remote and marginalized communities, as well as greening its power supply.
Progress on the installation of rooftop solar has been slow so far, impeded by a lack of affordability, consumer awareness and trained personnel, with only around 16 gigawatts installed versus a target of 40 gigawatts.
Microgrids, meanwhile, remain commercially unviable, and more impact — non-commercially minded — capital will be required to get such initiatives off the ground. Hearteningly, recent government initiatives signal progress on decentralized renewable energy, and this installation will be important in lowering grid load and emissions.
Where the funding could come from
All three prongs of India’s energy sector transition will require funding. According to expert estimates, India needs to spend around $100 billion per year, or 2.8% of current nominal GDP, to achieve net-zero power sector emissions by 2070.
With various imminent and urgent competing demands on the country’s budget, public finance will simply not be enough.
India will need to attract greater amounts of philanthropic, foreign, and private capital, as well as develop creative financing structures, to meet its net-zero target.
Each of these capital sources has a specific role to play.

While philanthropic capital can help in seed funding unproven new technologies ― for example, new battery technologies, nuclear, and green hydrogen ― greater foreign and domestic public capital can play a role in de-risking investments that so far generate lower-than-market returns (for example, microgrids). Finally, more private capital can help finance already commercially viable opportunities, including power distribution and renewables.
The good news is this: India’s mammoth endeavor to transition its power sector paves the way for significant growth across multiple sunrise sectors.
It opens up tremendous opportunities for investment and entrepreneurship across renewables and decentralized energy solutions, emerging technologies in battery storage, nuclear, green fuels, various segments of energy efficiency and in software/ digital capabilities.
India’s clean-tech ecosystem is already emerging, and energy-related enterprises, including those operating in renewables and energy efficiency, directly account for 70% of all green startups in the country.
As the transition ensues, more capital will be needed. With rising incidents of heatwaves crippling productivity whilst raising grid load across the country, and India simultaneously positioning itself as a global data center hub, there is no time to lose — the call for greater green and transition finance is now.

‘Repowering’ era for America’s aging wind energy industry begins, despite Trump’s effort to kill it
Published

On Inauguration Day, President Donald Trump issued an executive order indefinitely halting permits for new onshore wind energy projects on federal land, as well as new leases for offshore wind farms in U.S. coastal waters. The action not only fulfilled Trump’s “no new windmills” campaign pledge, but struck yet another blow to the wind industry, which has been hit hard over the past few years by supply chain snags, price increases upending project economics, public opposition and political backlash against federal tax credits, especially those spurring the fledgling offshore wind sector.
Nonetheless, the nation’s well-established onshore wind industry, built out over several decades, is generating nearly 11% of America’s electricity, making it the largest source of renewable energy and at times last year exceeding coal-fired generation. On April 8, the fossil-fuels-friendly Trump administration took measures to bolster coal mining and power plants, but as the infrastructure driving wind energy ages, efforts to “repower” it are creating new business opportunities for the industry’s key players.
This repowering activity has emerged as a bright spot for the wind industry, giving a much-needed boost to market leaders GE Vernova, Vestas and Siemens Gamesa, a subsidiary of Munich-based Siemens Energy. Following several challenging years of lackluster performance — due in particular to setbacks in both onshore and offshore projects — all three companies reported revenue increases in 2024, and both GE Vernova and Siemens stock have moved higher.
GE Vernova, spun off from General Electric a year ago, led overall onshore wind installations in 2024, with 56% of the U.S. market, followed by Denmark’s Vestas (40%) and Siemens Gamesa (4%).

According to the U.S. Energy Information Administration, installed wind power generating capacity grew from 2.4 gigawatts (GW) in 2000 to 150.1 GW as of April 2024. Although the growth rate for launching new greenfield onshore wind farms has slowed over the last 10 years, the U.S. is still poised to surpass 160 GW of wind capacity in 2025, according to a new report from energy research firm Wood Mackenzie.
There currently are about 1,500 onshore wind farms — on which more than 75,600 turbines are spinning — across 45 states, led by Texas, Iowa, Oklahoma, Illinois and Kansas. Virtually all of the wind farms are located on private land, and many of the largest ones are owned and operated by major energy companies, including NextEra Energy, RWE Clean Energy, Pattern Energy, Clearway Energy, Xcel Energy and Berkshire Hathaway‘s MidAmerican Energy, which generates 59% of it renewable energy from wind, including 3,500 turbines operating across 38 wind projects in Iowa.
A growing number of the turbines are 20-plus years old and nearing the end of their lifecycle. So increasingly, operators have to decide whether to upgrade or replace aging turbines’ key components, such as blades, rotors and electronics, or dismantle them altogether and erect new, technologically advanced and far more efficient models that can increase electricity output by up to 50%.
“What’s becoming clear is that more and more of the U.S. installed base [of onshore turbines] has exceeded its operational design life,” said Charles Coppins, research analyst for global wind at Wood Mackenzie, “and now operators are looking to replace those aging turbines with the latest [ones].”
To date, approximately 70 GW of onshore wind capacity has been fully repowered in the U.S., according to Wood Mackenzie, while an additional 12 GW has been partially repowered. The firm estimates that around 10,000 turbines have been decommissioned and that another 6,000 will be retired in the next 10 years, Coppins said.

Beyond the fact that aged-out turbines need to be upgraded or replaced, repowering an existing wind farm versus building a new site presents economic benefits to operators and OEMs. To begin with, there’s no need to acquire property. In fact, in certain situations, because today’s turbines are larger and more efficient, fewer turbines are needed. And they’ll generate additional electricity and have longer lifecycles, ultimately delivering higher output at a lower cost.
Even so, “there are some limitations on how much capacity you could increase a project by without having to go through new permitting processes or interconnection queues” to the power grid, said Stephen Maldonado, Wood Mackenzie’s U.S. onshore analyst. As long as the operator is not surpassing the allowed interconnection volume agreed to with the local utility, they can add electricity to the project and still send it to the grid.
Public opposition, Maldonado said, may be another hurdle to get over. Whether it’s a new or repower wind project, residents have expressed concerns about environmental hazards, decreased property values, aesthetics and general anti-renewables sentiment.
RWE, a subsidiary of Germany’s RWE Group, is the third largest renewable energy company in the U.S., owning and operating 41 utility-scale wind farms, according to its CEO Andrew Flanagan, making up 48% of its total installed operating portfolio and generating capacity, which also includes solar and battery storage.
One of RWE’s two repower projects underway (both are in Texas), is its Forest Creek wind farm, originally commissioned in 2006 and featuring 54 Siemens Gamesa turbines. The project will replace them with 45 new GE Vernova turbines that will extend the wind farm’s life by another 30 years once it goes back online later this year. Simultaneously, RWE and GE Vernova are partnering on a new wind farm, immediately adjacent to Forest Creek, adding another 64 turbines to the complex. When complete, RWE will deliver a total of 308 MW of wind energy to the region’s homes and businesses.
Flanagan noted that the combined projects are related to increased electricity demands from the area’s oil and gas production. “It’s great to see our wind generation drive the all-of-the-above energy approach,” he said. What’s more, at its peak, the repower project alone will employ 250 construction workers and over its operating period bring in $30 million in local tax revenue, he added.
In turn, the twin projects will support advanced manufacturing jobs at GE Vernova’s Pensacola, Florida, facility, as well as advancing the OEM’s repower business. In January, the company announced that in 2024 it received orders to repower more than 1 GW of wind turbines in the U.S.

Siemens Gamesa has executed several large U.S. repowering projects, notably MidAmerican’s expansive Rolling Hills wind farm in Iowa, which went online in 2011. In 2019, the company replaced 193 older turbines with 163 higher-capacity models produced at its manufacturing plants in Iowa and Kansas.
Last year, Siemens Gamesa began repowering RWE’s 17-year-old Champion Wind, a 127-MW wind farm in West Texas. The company is upgrading 41 of its turbines with new blades and nacelles (the housing at the top of the tower containing critical electrical components) and adding six new turbines.
In early April, Clearway announced an agreement with Vestas to repower its Mount Storm Wind farm in Grant County, West Virginia. The project will include removing the site’s 132 existing turbines and replacing them with 78 new models. The repower will result in an 85% increase in Mount Storm’s overall electricity generation while using 40% fewer turbines.
Preparing for ‘megatons’ of turbine recycling and tariffs
Another benefit of repowering is invigorating the nascent industry that’s recycling megatons of components from decommissioned turbines, including blades, steel, copper and aluminum. Most of today’s operational turbines are 85% to 95% recyclable, and OEMs are designing 100% recyclable models.
While the majority of mothballed blades, made from fiberglass and carbon fiber, have historically ended up in landfills, several startups have developed technologies recycle them. Carbon Rivers, for example, contracts with the turbine OEMs and wind farm operators to recover glass fiber, carbon fiber and resin systems from decommissioned blades to produce new composites and resins used for next-generation turbine blades, marine vessels, composite concrete and auto parts.
Veolia North America, a subsidiary of the French company Veolia Group, reconstitutes shredded blades and other composite materials into a fuel it then sells to cement manufacturers as a replacement for coal, sand and clay. Veolia has processed approximately 6,500 wind blades at a facility in Missouri, and expanded its processing capabilities to meet demand, according to David Araujo, Veolia’s general manager of engineered fuels.
Trump’s new-project moratorium isn’t his only impediment to the wind industry. The president’s seesaw of import tariffs, especially the 25% levy on steel and aluminum, is impacting U.S. manufacturers across most sectors.
The onshore wind industry, however, “has done a really good job of reducing geopolitical risks,” said John Hensley, senior vice president for markets and policy analysis at the American Clean Power Association, a trade group representing the clean energy industry. He cited a manufacturing base in the U.S. that includes hundreds of plants producing parts and components for turbines. Although some materials are imported, the investment in domestic manufacturing “provides some risk mitigation to these tariffs,” he said.
Amidst the headwinds, the onshore wind industry is trying to stay focused on the role that repowering can play in meeting the nation’s exponentially growing demand for electricity. “We’re expecting a 35% to 50% increase between now and 2040, which is just incredible,” Hensley said. “It’s like adding a new Louisiana to the grid every year for 15 years.”
GE Vernova CEO Scott Strazik recently told CNBC’s Jim Cramer that the growth of the U.S.’s electric load is the largest since the industrial boom that followed the end of the second world war. “You’ve got to go back to 1945 and the end of World War II, that’s the infrastructure buildout that we’re going to have,” he said.
As OEMs and wind farm developers continue to face rising capital costs for new projects, as well as a Trump administration averse to clean energy industries, “repowering offers a pathway for delivering more electrons to the grid in a way that sidesteps or at least minimizes some of the challenges associated with all these issues,” Hensley said.

ABB is bringing its new, 1.2 MW modular truck chargers to ACT Expo
Published

Capable of delivering up to 1,200 kW of power to get electric commercial trucks back on the road in minutes, the new ABB MCS1200 Megawatt Charging System is part of an ecosystem of electric vehicle supply equipment (EVSE) that ABB’s bringing to this year’s ACT Expo.
ABB E-mobility is using the annual clean trucking conference to showcase the expansion of its EVSE portfolio with three all-new charger families: the field-upgradable A200/300 All-in-One chargers, the MCS1200 Megawatt Charging System for heavy-duty vehicles shown (above), and the ChargeDock Dispenser for flexible depot charging.
The company said its new product platform was built by applying a computer system-style domain separation to charger design, fundamentally improving subsystem development and creating a clear path forward for site and system expansion. In other words, ABB is selling a system with both future-proofing and enhanced dependability baked in.
“We have built a system by logically separating a charger into four distinct subsystems … each functioning as an independent subsystem,” explains Michael Halbherr, CEO of ABB E-mobility. “Unlike conventional chargers, where a user interface failure can disable the entire system, our architecture ensures charging continues even if the screen or payment system encounters issues. Moreover, we can improve each subsystem at its own pace without having to change the entire system.”

The parts of ABB’s new EVSE portfolio that have been made public so far have already been recognized for design excellence, with the A400 winning the iF Gold Award and both the A400 and C50 receiving Red Dot Design Awards.
New ABB chargers seem pretty, good

ABB says the systemic separation of its EVSE enhances both reliability and quality, while making deployed chargers easier to diagnose and repair, in less time. Each of the chargers’ subsystems can be tested, diagnosed, and replaced independently, allowing for quick on-site repairs and update cycles tailored to the speed of each systems’ innovation. The result is 99% uptime and a more future-proof product.
“The EV charging landscape is evolving beyond point products for specific use cases,” continued Halbherr. “By implementing this modular approach with the majority of our R&D focused on modular platforms rather than one-off products … it reduces supply chain risks, while accelerating development cycles and enabling deeper collaboration with critical suppliers.”
Key markets ABB is chasing

- PUBLIC CHARGING – with the award winning A400 being the optimal fit for high power charging from highway corridors to urban locations, the latest additions to the A-Series All-in-One chargers offer a field-upgradable architecture allowing operators to start with the A200 (200kW) with the option to upgrade to 300kW or 400kW as demand grows. This approach offers scalability and protects customer investment, leading to Total Cost of Ownership (TCO) savings over 10 years.
- PUBLIC TRANSIT AND FLEET – the new Charge Dock Dispenser – in combination with the already in market available HVC 360 – simplifies depot charging with a versatile solution that supports pantograph-, roof-, and pedestal charging options with up to 360kW of shared power and 150m/490 ft installation flexibility between cabinet and dispensers. The dispenser maintains up to 500A output.
- HEAVY TRUCKS – building the matching charging infrastructure for commercial vehicles and fleets represents a critical innovation frontier on our journey to electrify transportation. Following extensive collaboration with industry-leading truck OEMs, the MCS1200 Megawatt Charging System delivers up to 1,200kW of continuous power — 20% more energy transfer than 1MW systems — providing heavy-duty vehicles with purpose-built single-outlet design for the energy they need during mandatory driver breaks. To support other use cases, such as CCS truck charging, a dual CCS and MCS option will also be available.
- RETAIL – the award winning C50 Compact Charger complements the family as the slimmest charger in its category at just 9.3 inches depth, optimized for convenient charging during typical one-hour retail experiences. With its large touch display, the C50 takes the award-winning A400 experience even further — setting a new standard for consumer experience and very neatly echoing our own take on that “Goldilocks” timing zone for commercial charging.
ABB says that the result of its new approach are chargers that offer 99% plus uptime — a crucial statistic for commercial charging operations and a key factor to ensuring customer satisfaction. The new ABB E-mobility EVSE product family will be on display for the first time at the Advanced Clean Transportation Expo (ACT Expo) in Anaheim, California next week, then again at Power2Drive in Munich, Germany, from May 7-9.
Electrek’s Take

The ACT Expo is one of – if not the most important sustainable trucking event in North America, featuring all the big names in heavy trucks, construction equipment, material handling, infrastructure – even Tier 1 suppliers. Mostly, though, it’s many fleet buyers’ only chance to test drive these zero emission trucks before writing a big PO (which just makes it even more important).
Electrek will be there again this year, and we’ll be bringing you all the latest news from press events and product reveals as it happens.

Whisper Aero ultralight aircraft scores $500K for “UltraQuiet” electric jet motor tests
Published

Along with Tennessee Tech, Tennessee-based ultralight aircraft company Whisper Aero has secured a $500,000 grant to help advance the company’s innovative electric jet motor concept off the drawing board and onto the testing phase.
Earlier this month, the Tennessee Department of Economic and Community Development (TNECD) announced plans to award $500,000 to Tennessee Tech and Whisper Aero through the Transportation Network Growth Opportunity (TNGO) initiative.
“We look forward to using these award dollars to place students in internships working directly with Whisper Aero leaders,” said Tennessee Tech President Phil Oldham. “By learning from an electric propulsion innovator like Whisper Aero, our students will gain invaluable perspective and can take what they have learned in the classroom and apply it right here in Tennessee.”
The grant will see a Whisper Aero glider fitted with a pair of the company’s eQ250 electric-powered jet “propulsors” for UltraQuiet flight. Tennessee Tech faculty and students will carry out copper-bird ground testing to ensure the safe integration of engines, batteries, and controllers, and kickstart Tennessee Tech’s new Crossville Mobility Incubator.

Those propulsors, by the way, are super cool.

Whisper Aero’s main claim to fame is its innovative UltraQuiet WhisperDrive (above). It’s effectively an electrically spun ducted fan jet engine that uses a large number of stiff composite fan blades inside a lightweight, acoustically treated duct. With so many blades, the Whisper Aero propulsor can push more air than a conventional prop while spinning much more slowly. As such, the “blade passage frequency” moves up to more than 16,000 Hz – outside the range of most human hearing but not, supposedly, high enough to freak out the beagles.
The Whisper Aero ultralight is effectively an Aériane Swift3 glider fitted with a pair of Whisper’s eQ250 propulsors, each capable of up to 80 lbs. of thrust. The Ultralight has a wingspan of over 40 ft with a maximum L/D of 35:1 and can be stressed to a design loading of +6/-4g, making it capable of some pretty impressive acrobatic feats.
The Swift3 glider is designed for a low speed, low power cruising speed of 45–55 knots with “just” 6.5 hp. Power-off glides from a few hundred feet showed a low sink rate, and a climb rate of 1,250 ft/min with full self-launching power (in other words: the Whisper glider doesn’t have to be towed by a launch vehicle, like a conventional ultralight glider).
Quiet cool

Range under full power is about 109 miles with current battery tech, but it’s expected that range under the latest EPiC 2.0 energy batteries would rise to nearly 170 miles.
Nathan Millecam, CEO of Electric Power System, said, “EPiC 2.0’s leap in energy density and thermal performance has enabled a significant increase in range, a clear validation of our next-gen cell technology. We are impressed by what the Whisper team continues to achieve in advancing electric aviation.”
The press release concludes explaining that flight tests are expected to show that the Whisper Aero glider can be flown, “a few hundred feet away from neighborhoods without any disturbances, while carrying a 220 lbs. payload with full range,” which is all kind of ominous in today’s political climate, but still pretty neat from a purely tech perspective.
The TNGO grant follows a separate grant from NASA awarded last year, though that grant aims to develop the eQ250s – not as a propulsion system, but as a key component in future spacecraft ventilation systems.
Tennessee Tech announces TNGO grant
With support from TNECD’s Transportation Network Growth Opportunity (TNGO) initiative, Tennessee Tech University and Whisper Aero are partnering to advance next-generation propulsion technology in the aerospace industry. This collaboration will enhance aerospace research and workforce development, ensuring Tennessee remains a leader in cutting-edge mobility solutions.
