That’s quite the achievement. Though a side note of comparison I can’t believe France and Belgium suffer power losses in the 5 to 6% range. Unless I’m misunderstanding what that means, it seems excessive for a modern economy.

3h agoHN ↗

It's embarrassing that it took so long. India has been crippled by decades of socialist government overreach. Unfortunately, even the purportedly right wing BJP is unable to keep the government out of places where it doesn't belong.

3h agoHN ↗

India has been crippled by decades of socialist government overreach.

It baffles me that country still has strong anti-capitalist views. I guess lack of education does that to people.

Also, BJP is slightly right of Congress (post 1991) when it comes to economics.

3h agoHN ↗

Being to the right of the current INC is not an achievement. The only people not in that position are Maoists.

Anyway, I think it's reasonable to be suspicious of the wealthy and powerful. For instance, I personally quite dislike our new AI ruling class. But unfortunately, in India there was an attitude since independence that it is impossible to generate wealth in a legitimate manner. Which is going way too far! And has predictably bad outcomes for the country.

3h agoHN ↗

Definitely not nearly as vile. It certainly wasn't perfect, particularly things like the awful penal colonies, but jump-starting a giant civilisation, say, 1000+ years into the future is not straightforward either. India is experiencing a rise in nationalism, but would do well to imagine the counterfactual of what India would be like had Europe never visited.

3h agoHN ↗

Not sure what you are suggesting here.

It's pretty clear lol. OP definitely thinks we were living in mud huts before the British gifted us railroads.

2h agoHN ↗

jump-starting a giant civilisation, say, 1000+ years into the future is not straightforward either

The various East India companies went to India (and the other east Indies) because those places had things rich Europeans desired - spices yes, but also high-end, high-quality textiles and handcrafted items. They were already the height of civilization and had high economic productivity.

would do well to imagine the counterfactual of what India would be like had Europe never visited

It would probably not be one country. Best case scenario: like a South Asian EU. Why do you think they wouldn't have copied European industrialization and developed themselves? Japan did it. Turkey did it.

Speaking of Japan, isn't it interesting that the first Asian country to industrialize is also one of the only Asian countries never colonized by Europeans? Why do people still believe colonization was good for economic development?

2h agoHN ↗

Speaking of Japan, ...

IIR, Japan was a pretty xenophobic, unified, and militarized place when the Europeans showed up. And without either reputed or obvious Tier 1 riches - such as Central & South America's precious metals - to motivate a hard-fought conquest. Especially when 'most everywhere else in South & East Asia was comparatively easy pickings.

Why do people still believe ...

Because, if you use sufficiently Eurocentric metrics, it usually was. And picking those metrics feels pretty good, if you identify uncomfortably closely with that sort of capitalism.

1h agoHN ↗

Japan was a pretty xenophobic, unified, and militarized place when the Europeans showed up.

Other than unified, that describes most places in the 15th or 16th century.

Because, if you use sufficiently Eurocentric metrics, it usually was.

The one country in Asia* to not suffer colonialism (Japan) is way ahead of all the others that did have it, especially on "Eurocentric" metrics such as GDP and productivity and democracy and human rights. That alone should be a rebuke to colonialism's purported development powers.

* Arguably Thailand is another but it was forced to cede land to colonial powers. It too is considerably richer than its immediate neighbors.

3h agoHN ↗

It baffles me that country still has strong anti-capitalist views.

I wouldn't call the "license raj" of India as anti-capitalist. India arguably has the strongest of institutions of all the countries in South Asia. However, even its institutions and regulations are pathetically weak.

https://en.wikipedia.org/wiki/Bhopal_disaster

You probably also saw a previous post right here on this orange website when someone tried to repatriate their business money outside of India. It was painful just to read that they had to get approvals from iirc sixteen different government agencies to get their own money that they brought in from outside of India back. Not profits, not proceeds, a fraction of what they put in.

Neither of these two cases is due to "anti-capitalist" views of India. If you look at what was India before Moghul rule and British rule, you could argue India has never been socialist before.

I think workers everywhere should have "strong anti-capitalist views", because unrestrained capitalism is just anarchy.

3h agoHN ↗

I think that's a bad read of Indian institutions. They are incredibly powerful - in fact, they are far too powerful. That's the problem. The license raj is the epitome of authoritarian, centralized political and economic power. I suppose it was justified on socialist grounds, but it would be fair to say that saying so doesn't make it so! Before 91, nothing, and I mean nothing, could happen without government say-so.

The problem with Indian institutions is that they are far too powerful, centralized and bureaucratic. Just read the article - the problem was created by a lazy, corrupt, powerful and centralized bureaucratic system. The solution was to dismantle it and decentralize power.

3h agoHN ↗

I apologize I am not very good at expressing myself. Could India be better? Of course! Anyone can be better than what they are. Like a fish that lives in water doesn't ever think about water, an Indian living in India does not think about the absurdity of how powerful a District Collector / District Magistrate (DM) / Deputy Commissioner (DC) is in contemporary India.

What you are saying is absolutely true. the bureaucracy in India is absolutely lazy, corrupt, powerful, and centralized. It is also arguably one of the biggest reasons why India has never had a (successful) military coup. You could even argue the inefficiency and the sluggishness of the bureaucracy is a feature and not a defect.

2h agoHN ↗

I think this is a self-deprecating canard that's oft-repeated, but I think fails the credibility test and encourages a kind of fatalistic resigned attitude among Indians. Are we to take from this that efficient bureaucracies lead inevitably to coups? Is the pathetic state of most African countries a result of their stellar bureaucracies?

3h agoHN ↗

True it should never have gotten so bad, but when there is no incentive to invest, this is the result you can expect. This happened in Venezuela and South Africa too - though SA also suffers from massive corruption (officials pocketing moneys and diverting from investment in infra).

The privatisation of Delhi power distribution was initiated by a Congress state government in 2000.

3h agoHN ↗

I am aware. The initial privatization push was initiated by Congress in 1991! My lament is that privatization has remained anemic, even under the so-called right wing BJP.

But you should also acknowledge that national electrical reform was done by BJP. The real problem for Indian politics was the re-entry of the Gandhi nepo-baby dynasty. We would be a lot better off if they hadn't gotten their claws back into the INC.

3h agoHN ↗

It's not surprising. For one, stated vs actual goals always differ and someone needs pockets to reach into. For the other, plenty of countries that listened to orgs like the World Bank saying "privatise everything immediately and reap the benefits!" just ended up handing the assets to cronies. Examples like Russia are of course well-known, but it's obviously happening under BJP in India as well.

3h agoHN ↗

It's once again lamentable, but somewhat predictable that even on a post about how privatization fixed, in five years, a problem that persisted for 50, you insist on spreading boogeyman tales about privatization. The Indian government is what American libertarians are afraid of, and in their defense, they should be afraid.

3h agoHN ↗

Boogeyman? Is the outcome of the World Bank's insistence on "structural adjustments" somehow in debate now?

I was in Delhi when this started and they began laying out the tamper-proof cable back in the early 2000s. At that time, railway food had been privatised, perhaps you recall. It wasn't better. The problem was not the privatisation or lack thereof, it was the complete lack of accountability.

2h agoHN ↗

you insist on spreading boogeyman tales about privatization

Dude, you're the one coming across as a zealot here.

1h agoHN ↗

Privatization doesn't fix shit. Competition does. A private monopoly is just as bad as the government.

3h agoHN ↗

The BJP is marginally less socialist than the Congress. On the positive side, they are definitely less corrupt than the Congress.

2h agoHN ↗

Has the Congress moved to the right?

The License Raj prior to 1991 was pretty socialist, and it was a Congress policy.

2h agoHN ↗

Really? The recent headlines would suggest otherwise.

3h agoHN ↗

To me transformation efficiency and distance losses actually seem to make 5-6% pretty impressive?

3h agoHN ↗

30 years ago my local electric co-op was bragging they got transmission losses down to 4%, when the rest of US was 8% (I'm not sure if that is average or some other statistical term).

But yes, transmission losses exist and are surprisingly large

3h agoHN ↗

every step in the chain loses power. You lose power just in the power lines. Every trip through a transformer adds some more loss

Reducing the number of transformers, raising the high side of system voltage, and increasing conductor sizes are all ways to reduce the transmission losses. of course each of those requires investments so that's why it can be variable and also something to brag about

2h agoHN ↗

Correct. As I recall the did a customer survey and customers didn't like (among other things) the number of power outages. The main goal was fixing that, and several side effects of that resulting in less line loss.

1h agoHN ↗

It's mostly about the distance, isn't it? Iirc even with the most modern ultra high voltage lines, it's about 3% per 1000km. Which honestly doesn't sound too bad, even for really long distances (like solar power from some desert to where people actually live).

1h agoHN ↗

Distance is a factor. I do not know what they were measuring (the main power plant was about 1000km away, but I don't know if they counted that or if that was ignored because someone else owned those lines). They were a fairly rural utility with most of the area belonging to farmers (but they do have a couple suburbs and a few small towns).

I don't know the real details, but my educated guess is they raised the voltage, and also they used 3x as many wires (running 3 phase past every house even though almost everybody only used 1 phase). That is I can visually see their insulators on the power posts are larger than neighboring utilities which allows for higher voltage (but may or may not mean higher voltages were used). Likewise I can see the 3 lines on each power pole while neighboring utilities only used one. It is hard to tell from the ground but I suspect they used thicker wires as well.

3h agoHN ↗

I'm not sure what that percentage means, but power-cuts in Belgium are extremely rare.

3h agoHN ↗

I don't think that number is correct?

In the 39 years I live here, the only power loss was due to lightning or planned power cuts because of work in the building where I live in the last 9 years ( rare - twice).

There is however incentive for our high chemistry industry to cut the power and they get re-imbursed. This is when we have too much electricity production ( solar power) vs. consumption. Otherwise the providers have to pay "fines" to lose the overproduction of electricity to neigboring countries ( who probably all have overproduction of electricity).

2h agoHN ↗

5-6 percent of electricity loss just mean that 5-6 percent of the electricity produced by all power plants in your country never reach the customer. Not that you have blackouts 5-6 percent of the time.

As of now, we cannot do lossless transmission. If some Ultragrok comes with room-pressure and room-temperature superconductors, then maybe.

2h agoHN ↗

Czechia is at 5-6 per cent as well, even though our grid companies are quite good. This is the price for having rural areas. Within a single compact city, like Singapore, you can get under 1 per cent easily. One the distances grow to hundreds of kilometers, some non-negligible loss is inevitable.

2h agoHN ↗

It’s where you’ll find most countries with a good handle on their electric network, advanced economies or not. You can do better but it requires either very small service distances (so you don’t have transmission losses in the first place) or an extreme dedication to hunting them down.

3h agoHN ↗

In Greece there is no incentive to fix power losses since the electric bill has a power losses line item.

You can steal as much as you want. The ones who pay will pay.

3h agoHN ↗

"The ones who pay will pay" is always true (from people using public transport without a ticket to "normal" tax payers having to shoulder the losses caused by loopholes and "incentives" for the upper 0.1%), but resigning to it so explicitly is rare.

2h agoHN ↗

caused by loopholes and "incentives" for the upper 0.1%

You'd be amazed at how most of this sort of thing is not done by the same people you blame for everything.

2h agoHN ↗

Yeah. My impression is, small players exploit the loopholes like there's no tomorrow, big players hire external consultants to give them least-effort playbook and take over liability, as anything more clever is exponentially more expensive.

2h agoHN ↗

How is creating your own ETFs to avoid paying taxes low effort?

I mean, it's very low effort to have somebody else do all the work. But you'll never see a self-employed electrician creating an account in the Cayman Islands to avoid taxes.

2h agoHN ↗

You'll see a load of people on benefits being tax-negative, though. If paying taxes is your measure, then an honest assessment of who pays taxes wouldn't land you at the ultra-rich.

1h agoHN ↗

One of the funniest ideas I heard was that we in South Asia do corruption properly, because unlike the West, even the poorest person gets to be corrupt while in the West you have to have money and know people. Democracy!

21m agoHN ↗

It's just not true at all though, and I don't get where the meme comes from other than the politicians pointing their fingers at the rich so we don't look at them. If there wasn't incentive to be homeless, we wouldn't have so many.

3h agoHN ↗

I mean this is the case universally, even if the losses aren't in a specific line item the cost of generating that power has to be covered overall

There's usually an incentive to solve this though because this shrinkage, in retail terms, would be handled at the cost of power generated (without any profit margin) whereas if it was sold to a paying customer it'd have a margin built in. If the Greek utilities are allowed to make a profit on that losses line item, that is insane

2h agoHN ↗

If a utility is regulated to a set profit outcome, it will make a profit on stolen electricity just via math.

2h agoHN ↗

it depends on how the regulations are written. not every single cost gets to go into the guaranteed return on equity. Probably plenty of examples where it is, but also there are definitely a lot of examples where that's not true. Given how militant most utilities are at preventing theft, either parent comment OP is just being cynical or there is something very off about the situation there vs. most places

3h agoHN ↗

The ones who pay will pay.

Until solar panels came to liberate us from the utility overlords.

2h agoHN ↗

And handed us over to the mafias that collect protection money for solar panels.

A failed state will be fail-stating regardless of the technology.

2h agoHN ↗

Indeed, you need to insure from the risk of brick-rain where this weather phenomenon occurs!

2h agoHN ↗

In places where the grid is reliable, approximately no one disconnects voluntarily from it, and solar panels are just a nice extra.

It is the places where the grid is failing where solar panels indeed liberate you, but not from the utility overlords, but from incompetent and corrupt governance.

3h agoHN ↗

I wonder how many HNers recall life in Delhi even 20 years ago? Cutting electricity loss is one thing, but getting rid of "load shedding" (unplanned power cuts) is the really revolutionary part. It was not uncommon for the power to go out several times a day and you had to rush to unplug expensive appliances (TV, laptop), because when the power came back it was often accompanied by a surge. My office was wired with two sets of electrical sockets, one connected to grid mains and the other connected to the UPS (for important equipment only).

3h agoHN ↗

unplanned power cuts

Actually load shedding is planned power cuts. I have seen a schedule published in a newspaper with different regions of the city (not Delhi) and times when no electricity will be available. This is for ppl to plan their day

3h agoHN ↗

Load shedding = it was done on purpose, not that it was pre-planned. If a sudden problem occurs, some areas can be cut to prevent wider failure. I would expect this to be largely automatic.

1h agoHN ↗

There was some priority order to determine which circuits should be load-shed when there is a power shortage. For example while scouting datacenter sites across Delhi, Mumbai and Chennai, I learnt that 220KV lines were not part of load-shedding schedule whereas 66KV lines were. If you took power directly from the power generation company and had contracted power then also you were protected.

2h agoHN ↗

I suspect the semantics are about how long in advance it's planned. A day or two? Planned. An hour? Hard sell.

1h agoHN ↗

Far enough in advance to be available in a printed newspaper. Planned.

1h agoHN ↗

Planned for the electric officials, unplanned for the consumers.

Nowadays, power cuts are announced via SMS in advanced. Before, this was not the case.

3h agoHN ↗

Do you remember the scheduled water cuts? We would stockpile water in buckets so we could flush the toilets. Good old days!

3h agoHN ↗

I remember the inverse of that in Chennai -- scheduled running water for an hour in the morning and an hour in the evenings when we had to stockpile water in every container possible.

3h agoHN ↗

It's so weird reading these comments, we didn't have either of these issues in Gujarat in early 2000s (left India in mid 2000s).

Riots in India are uncontrollable. Muslims killed 59 Hindus returning from Ayodhya by burning a train full of innocent karsevaks which started the riots

I still remember those summer midnights, without cooler

2h agoHN ↗

We've traded power cuts for pollution. The current government seems energetic enough in trying to fix the problem, but frankly it's something every single developed country in existence went through at some point, so there's probably no escaping it. Hopefully the pollution era will be shorter than it was in other places!

2h agoHN ↗

It's good to hear there have been improvements in some areas of life at least.

2h agoHN ↗

I spent two weeks in Bangalore in 2014. Power cuts happened roughly every other day.

Thankfully, I stayed in a nice hotel with an automatic generator, so the power would cut out for a second or two before the generator came on, and then would cut back out for a second or two a few minutes later when the hotel went back on the mains.

1h agoHN ↗

Depends on the season. Until a few years ago Bengaluru had a different problem – when it thundered or rained, they would cut power to protect transformers from shorting out due to falling trees on power lines.

2h agoHN ↗

I wonder how many HNers recall life in Delhi even 20 years ago?

The only thing I know about India is from a Big Bang Theory episode where Raj's father said to Leonard when asked how's the weather, "It's hot, it's always hot in India!".

1h agoHN ↗

2h agoHN ↗

Sounds similar to life in Dhaka in the 1980s. I remember many sleepless nights where the power went out for no discernible reason and our air conditioner (a window unit in my parent’s bedroom) stopped working. My understanding is that this has gotten much better in Dhaka over the last decade, though the recent energy crisis set things back.

1h agoHN ↗

Every second house had a diesel generator back then. Ours had to be cranked started by hand(not for the heartless) before push button starters became a thing. The shutoff though was simple tug on the switch; I attached a twine that ran to my bedside for shutoff, which was a godsend at 2:00 AM when the power came back on to make those crazy summer days a bit easier to sleep through.

I wonder how many HNers recall life in Delhi even 20 years ago?

I wonder how many HNers are, or ever have been there in the first place? It seems strange to me to ask who "recalls" what it was like there before. What would such a recollection be based on? There's only so much attention one can pay to what daily life is reportedly like around the world, and that required believing the reports.

In areas where theft was particularly rampant and losses were as high as 83 percent, according to Tata, the companies took a different strategy. These pockets of Delhi were predominantly occupied by low-income families. Tata Power, and later BSES, worked to improve the water supply for these residents and provide educational opportunities, such as instruction in reading and writing in Hindi as well as financial literacy. These efforts focused on the women, who were at home more, and paid them to collect electricity payments from their neighbors. Bill payment rates from these areas are now on par with those of other parts of Delhi

This is... interesting on multiple levels.

I want to know what Singapore's grid operators have been up to. That seems to be the more interesting story based on the data in this article.

3h agoHN ↗

Singapore is a very small city. Distribution losses are linear with distance!

1h agoHN ↗

It seems to be an investment in underground distribution structures and advanced monitoring including predictive failure analysis.

However there's kind of a funny part to it that I read on the last page of New Scientist some years ago. According to that story, Singapore has by far the lowest rate of accidental line cuts - it's a step change to almost zero from the next best country. Apparently there's a worldwide organization that meets to discuss these things. At one meeting the Singaporean engineers presentation was eagerly anticipated but as he was going through his points the engineers from other countries were impatient - they know and do all this! Until he got to his final point: accidental line cuts in Singapore result in 10-year prison sentence. Hence the difference.

So basically theft and fixing overloaded infra. So this is policy based solutions for the most part.

Amazing that places have 50% power loss.

2h agoHN ↗

In Hyderabad, India the govt loses around 2 million kWh per day(roughly 50-60 million USD per year) in theft and unpaid electricity bills every year particularly the old city area where residents refuse to pay the bills.

Bill collectors are openly threatened by local elected leaders even in the presence of police.

The state chief minister(similar to a governor) acknowledged the problem and is planning to handover bill collection to a private firm specifically for that part of the city. The opposition is against the move as the area represents a major voting bloc.

Sometimes, policy based solutions work but political will is also necessary to enforce those policies.

Estonia?!

Much has been made of Estonia having a high tech virtual government I’d. So many high tech start ups have come from Estonia, I’m a bit stunned that they have big electricity distribution problems.

3h agoHN ↗

This is some kind of totally wrong reporting. Maybe some other country was meant, or the author mixed us up with Elbonia from Dilbert.

We do not have issues with electricity here or planned power cuts or whatever else.

I would like to see where this professor got his data for losses from. Maybe his data is flawed.

2h agoHN ↗

Albania, Argentina, Bangladesh, Brazil, Estonia, India, Kenya, Pakistan, Sri Lanka, Uganda, and Venezuela

Even if Estonia does have stated electricity distribution loss, it still looks so way out of place in this group of countries by so many criteria. I wonder why not pick Egypt or Libya given that they have the same distribution loss.

Edit: this could be the reason - when you click on "Map" above the graph, for some reason Estonia is one of the blue countries shown on the map. Argentina, Brazil, and Kenya are there too (but not others).

1h agoHN ↗

Interestingly, this page seems to contain data only until year 2014, but the graph next to Estonia in the grandparent link does show an increase on the right side. Maybe Estonia did indeed experience some changes in overall distribution loss in recent years?

1h agoHN ↗

The article also says Brazil's "problems look like Delhi’s 25 years ago", which is very incorrect from what they're describing. Almost none of what is described in the article happened in Brazil 20 years ago, let alone today. Energy theft, for instance, happens here but at a minuscule scale compared to what's on the article.

I also doubt Estonia has any of these issues whatsoever, like energy theft.

It really seems like a vibecoded article with numbers informing incorrect conclusions. Perhaps with a dash of nationalistic pride. Unfortunate from IEEE.

2h agoHN ↗

It may be that they over-generate currently to account for the excess losses, which would be very costly given current fuel prices unless most of it is from environmental sources.

1h agoHN ↗

In Estonia we def do not over generate by that amount.

1h agoHN ↗

It doesn't need to be that amount, just a significant amount, to be worth mentioning. Though even if that much were true, you would have unusually high electricity bills at home [much like we do in the UK, but that is because our national grid is a privatised mess effectively run by external concerns (EDF have their fingers in the pie, for one example) charging us much more than they can get away with in their home markets].

2h agoHN ↗

As far as I can tell, that number comes from the World Bank and it defines electricity loss as a percentage of domestic production. But Estonia imports a lot of its electricity, and that imported electricity is not included on the generation side of the equation.

tldr; they passed the administration of power from the corrupt government officials to Tata power (part of the Tata conglomerate) and BSES (part of another conglomerate Reliance). They modernized the setup and closed loopholes and avenues of corruption and also made stealing of power by the corrupt sections of public difficult.

A well functioning government that regulates things is so crucial to everything in a technological life.

India has one thing going for it, sunlight all the time.

India can adopt plug-in standards, solar and batteries. I guess most people use some form of battery (UPS/Inverter) anyways, so the idea is familiar.

Rooftop is known and it can continue to grow. Next, add vertical solar. This will add ~4 hours of solar production.

Required gated communities to be self sufficient or net producers. Cover the surfaces of all high rises with vertical panels. Require these communities to have BESS and EV charging for all car parking. This adds two layers of storage. BESS instead of diesel generators. Add outlet for induction stove. No need of piped gas. I've seen villa communities where most homes are net producers, these ideas are happening, need to be standardized as regulation. Easiest thing is to create standards for the gated communities, which can be enforced.

Don't build rural transmission infrastructure. They can be offgrid, using solar and batteries. It is not worth the cost to build and maintain transmission and distribution infrastructure to millions of small villages.

Work towards regulating uber/rapido to require EV cars. These drive the most miles in cities and would do wonders.

Lots of scope for growth.

Great, sounds like youve planned for the 1/3 of the electrical load that residential usage represents.

How did you get that number? Is this just a quip about batteries?

Most of India has a solar capacity factor >0.2 and low seasonality. That means even 5kW peak rooftop panels and a 10 kWh battery will get you over 95% almost always. And panels+labor is so cheap in India, there's really no reason not to just tile the roof in panels.

Things get more difficult in dense cities, if you have multi story apartment blocks going 90+% locally is impossible. But then just transmit power from lower density rooftops, or actual solar farms.

And this already assumes widespread AC (really no way to increase electrification this much and not add AC in that climate).

Ember Energy: Battery storage is now cheap enough to unleash India’s full solar potential - https://ember-energy.org/latest-insights/battery-storage-is-... - April 7th, 2026 ("Ember’s analysis shows how solar and battery storage can meet as much as 90% of India’s electricity demand at lower LCOE than the average power purchase costs in most states.")

- Solar and batteries could supply 90% of India’s electricity demand at a competitive LCOE of around INR 5.06/kWh ($56/MWh).

- 4.9 GW of solar and 13.5 GWh of battery capacity for every 1 GW average demand load is enough to meet 83-92% of annual electricity demand in the ten largest states.

- 7 of India’s largest states by electricity demand can meet 90-92% of their demand with solar and batteries at an LCOE between INR 4.96–5.09/kWh ($55–56/MWh).

- 27% of India’s electricity was generated from clean sources in 2025. It was the 3rd largest country by electricity demand.

- As of March 2026, India was one of only ten countries planning to triple non-fossil generation capacity from 2022 levels by 2030. By December 2025, the country had achieved 258 GW of installed renewables capacity, making progress towards its 2030 goal of 500 GW. Ember analysis suggests that, under current plans, renewables would reach 42% of generation by 2030.

Rooftop solar use had and continues to explode in most tier 2 cites where its seen as a great way to save on electricity bills by feeding that power back to the grid. Its one of the few bright spots in a country with relentless expenses and price pressures.

I grew up in Delhi during the 90s. We used to have daily power cuts but starting around year 2000 (can't pin exact year), we started having less outages. Since around 2006, we had almost no outages throughout the year. Now, I haven't experienced a power outage in a long time in Delhi

I was curious if the price per unit of electricity has also changed over this time period, looks like that's been pretty much flat: https://ibb.co/8DLPn25D

(I assume consumption per customer has probably gone up)

Very difficult to raise electricity prices in retail areas in INdia. Political protests follow quickly. Also IIRC 30-40% waste in some places is almost always politically sanctioned theft. This is in addition to a lot more money lost as some entities that are politically controlled (e.g. Sugar factories in my state) purposely do not pay or delay. It is a miracle that the DISCOMs do not end up like neighboring Pakistan. It is like an invisible bargain with a lot of voting population and especially farmers (where no distinction is made between large land holding 1% vs others) who are routinely given free electricity. Cross subsidy is in the DNA of India.

Well written. It describes the problem at a fairly high level for engineers to understand and for lay people to see how public policy works when it does.

The next 25 years will see another revolution, the solar residential (and hopefully commercial one) https://pmsuryaghar.gov.in/#/

The government is actively encouraging solar residential and net metering is on...

Since the topic is linked to Delhi..

In dino, garche dakkan mein hain kadre sukhan bahut,

Kaun jaye Zauq, par dilli ki galiya chodd ke

The poet acknowledges that the Deccan region (South India) currently offers better patronage and respect for poets than the declining Delhi. However, he rhetorically asks who could possibly bear to leave Delhi....

The effort to reduce electricity theft has had an interesting side effect. One of the ways to prevent theft is to insulate the power lines going into neighborhoods. This also makes them safe for monkeys to use as 'roads' with the result that roving gangs of monkeys move from neighborhood to neighborhood with ease and also have access to the upper floor of apartment buildings because of the proximity of the power lines. I saw this in person a few years ago.

This is going to get a lot of press and it does not mention any ministers or government services. The guy who wrote it is getting transferred in a week.
