The Egbin Thermal Power Station, a few miles outside Lagos, is Nigeria's largest generating plant, with a capacity of 1,320 megawatts. It has six units, but two have been cannibalized to repair the remaining four, and at peak hours only two turbines are functioning. On bad days, like the first week in November, when the gas supply line was sabotaged, the plant shuts down altogether.

Not surprisingly, morale is low. "We are told of massive funding, but the funding never gets here," says Akintoye, an engineer at the plant. "We don't have spare parts. The contractors who built the plant are not given the maintenance contracts, which are determined by the regime in power. Even if we are operating optimally we can't serve Lagos, with a population of ten million."

So it goes in Africa's largest city, in a country with more oil than any other on the continent. For large parts of the day, Lagos is without power. After 8 P.M., darkness reigns. At best Nigeria generates 4,000 megawatts of electricity for its 140 million people, one-tenth of what South Africa produces for a population one-third as large.

Most businesses in Nigeria, large and small, get around the problem by generating their own electricity and using the national grid only as a backup. Foreign investors are told to BYOI - bring your own infrastructure.

When MTN, a South African mobile-phone company, set up shop in Nigeria, it had to install 6,000 generators to supply its base stations for up to 19 hours a day. The company, now the largest mobile-phone provider in Nigeria, spends $5.5 million a month just on diesel fuel to run its generators. "We rely on generating plants as our primary source of power," says Wale Goodluck, MTN Nigeria's manager for regulatory affairs.

The same is true for small businesses. Barbers, welders, and bakers all rely on their own power supplies, which is three times costlier and far more polluting than getting electricity from the national supply system. "I can employ 50 more tailors, but the power outage is wrecking my business," says Okorie Idika, who owns a shop that makes babariga, traditional garments. "I can't run this operation on generating plants. I won't be competitive."

It wasn't always this bad. Nigeria used to have 79 power stations. When civilian rule was restored in 1999, only 15 were still functioning, generating just 1,500 megawatts of electricity. Olusegun Obasanjo, who became President after the military regime, spent $8.5 billion repairing and building power stations, but the output has not increased significantly. Emmanuel Adewole, an economics professor at Lagos State University, calls it "the most expensive darkness in the world."

The World Bank estimates that the country is losing about $600 million a year because of inadequate supplies of electricity. Nigeria's new President, Umaru Yar'Adua, has called the power situation "abysmal," saying it has stunted the country's economic growth, and he has pledged to make fixing it a priority of his administration.

But the task is daunting. One problem: getting gas to the plants from the Niger delta, where rebels regularly vandalize pipelines. Corruption also runs deep, and consumers, who see no need to pay their energy bills, owe billions of dollars to the state-owned Power Holding Corp. of Nigeria. (Prepaid cards are increasingly being used, but in a country where everyone is an electrician, many have figured out how to bypass the meters.) The government wants to privatize the company and is taking bids for power-generating plants from 400 local and foreign investors. Ultimately, only the transmission platform will be held in trust by the government.

Until then, Nigeria's environment will continue to take a beating. Because of power outages, most families, in both urban and rural areas, use firewood as fuel for cooking. Swaths of forests are being hacked down daily to meet this need. And millions of diesel generators only add to the environmental burden. "Even the architecture of premises and houses is designed around generating sets," says Uma Obasi, a logistics expert with British American Tobacco in Lagos. "The din from these plants is literally driving people crazy."

China's electric power woes cast clouds on U.S. solar's near-term future

China Power Rationing disrupts the solar supply chain as coal shortages, price controls, and dual-control emissions policy curb electricity, squeezing polysilicon, aluminum, and module production and raising equipment costs amid surging post-Covid industrial demand.

 

Key Points

China's electricity curbs from coal shortages, price caps, and emissions targets disrupt solar output and materials.

✅ Polysilicon and aluminum output cut by power rationing

✅ Coal price spikes and power price caps squeeze generators

✅ Dual-control emissions policy triggers provincial curbs

 

The solar manufacturing supply chain is among the industries being affected by a combination of soaring power demand, coal shortages, and carbon emission reduction measures which have seen widespread power cuts in China.

In Yunnan province, in southwest China, producers of the silicon metal which feeds polysilicon have been operating at 10% of the output they achieved in August. They are expected to continue to do so for the rest of the year as provincial authorities try to control electricity demand with a measure that is also affecting the phosphorus industry.

Fellow solar supply chain members from the aluminum industry in Guangxi province, in the south, have been forced to operate just two days per week, alongside peers in the concrete, steel, lime, and ceramics segments. Manufacturers in neighboring Guangdong have access to normal power supplies only on Fridays and Saturdays with electricity rationed to a 15% grid security load for the rest of the time.

pv magazine USA reported that a Tier 1 solar module manufacturer warned customers in an email that energy shortages in China have forced it to reduce or stop production at its Chinese manufacturing sites. The company warned the event will also affect output from its downstream cell and module production facilities in Southeast Asia.

The memo said that in order to recover from the effects of the “potential Force Majeure event,” it may delay or stop equipment delivery or seek to renegotiate contracts to pass through higher prices.

Raw material sourcing
With reports of drastic power shortages emerging from China in recent days, the country has actually been experiencing problems since late June, and similar pressures have seen India ration coal supplies this year, but rationing is not unusual during the peak summer hours.

What has changed this time is that the outages have continued and prompted rationing measures across 19 of the nation’s provinces for the rest of the year. The problems have been caused by a combination of rising post-Covid electricity demand at a time when the politically-motivated ban on imports of Australian coal has tightened supply; and the manner in which Beijing controls power prices, with the situation further exacerbated by carbon emissions reduction policy.

Demand
Electricity demand from industry, underscoring China’s electricity appetite, was 13.5 percentage points higher in the first eight months of the year than in the same period of 2020, at 3,585 TWh. That reflected a 13.8% year-on-year rise in total consumption, following earlier power demand drops when coronavirus shuttered plants, to 5.47 PWh, according to data from state energy industry trade body the China Electricity Council.

Figures produced by the China General Administration of Customs tell the same story: a rebound driven by the global recovery from the pandemic, as global power demand surges above pre-pandemic levels, with China recording import and export trade worth RMB2.48 trillion ($385 billion) in January-to-August. That was up 23.7% on the same period of last year and 22.8% higher than in the first eight months of 2019.

With Beijing having enforced an unofficial ban on imports of Australian coal for the last year or so – as the result of an ongoing diplomatic spat with Australia – rising demand for coal (which provided around 73% of Chinese electricity in the first half of the year) has further raised prices for the fossil fuel.

The problem for Chinese coal-fired power generators is that Beijing maintains strict controls on the price of electricity. As a result, input costs cannot be passed on to consumers. The mismatch between a liberalized coal market and centrally controlled end-user prices is illustrated by the current situation in Guangdong. There, a coal price of RMB1,560 per ton ($242) has pushed the cost of coal-fired electricity up to RMB0.472 per kilowatt-hour ($0.073). With coal power companies facing an electricity price ceiling of around RMB0.463/kWh ($0.071), generators are losing around RMB0.12 for every kilowatt-hour they generate. In that situation, rationing electricity supplies is an obvious remedy.

The crisis has been worsened by the introduction of China’s “dual control” energy policy, which aims to help meet President Xi Jinping’s climate change pledge of hitting peak carbon emissions this decade and a net zero economy by 2060, and to reduce coal power production over time. Dual control refers to attempts to wind down greenhouse gas emissions at both a national level and in more local areas, such as provinces and cities.

Red status
With the finer details of the carbon reduction policy yet to be ironed out, government departments and provincial and city authorities have started to set their own emission-reduction targets. In mid-August, state planning body the China National Development and Reform Commission (NDRC) published a table of the energy control situation across the nation. With nine provinces marked red for their energy consumption, and a further 10 highlighted as yellow, officials received another motivation to introduce power rationing.

The current approach of rolling blackouts seems unlikely to be a sustainable solution, as surging electricity demand strains power systems worldwide, given the damage it could inflict on industry and the resentment it would cause in parts of the nation already preparing for winter.

The choice facing China’s policymakers is whether to ramp up coal supplies to force prices down by using decommissioned domestic supplies and halting the ban on Australian imports, or to raise electricity prices to prompt generators to get the lights back on. While the drawbacks of raising household electricity bills seem obvious, the first approach of using more coal could endanger the nation’s climate change commitments on the even of the COP26 meeting in Glasgow, Scotland, in November. Sources close to the NDRC have suggested the electricity price may be set to rise soon.

GDP
What is clear is the effect the energy crisis is having on the Chinese economy and on the solar supply chain. Leading up to a  national day holiday in China, the coal price in northern China rose to around RMB2,000 per ton ($310), three times higher than at the beginning of the year.

Investment bank China International Capital Corp. blamed the dual control emission reduction policy for the electricity shortages. It predicted a 0.1-0.15 percentage point impact on economic growth in the last quarter of 2021.  Morgan Stanley has put that figure at 1% in the current quarter, if industrial output restrictions continue. And Japan’s Nomura Securities revised down its annual forecast on Chinese growth from 8.2% to 7.7%. It now expects GDP gains in the third and fourth quarters to cool from 5.1% to 4.7%, and from 4.4% to 3%, respectively.

UK families living close to nuclear power stations could get free electricity

UK Nuclear Free Electricity Incentive proposes community benefits near reactors, echoing France, supporting net zero goals, energy security, and streamlined planning, while addressing regulation and judicial review challenges for Sizewell C and future nuclear projects.

 

Key Points

A proposed policy to give free power to residents near reactors, supporting net zero and energy security.

✅ Free power for communities near nuclear plants

✅ Aligns with net zero and energy security goals

✅ Seeks streamlined planning and fewer approvals

 

UK Business Secretary Jacob Rees-Mogg has endorsed a French-style nuclear system that sees people living near nuclear power stations receive free electricity.

Speaking at an event organised by Policy Exchange think tank, Jacob Rees-Mogg said: “Nuclear power is just fundamental. There’s no way we can get to net zero emissions, or even have an intelligent electricity strategy and grid reform in the UK, without nuclear.”

Highlighting that this was his view and not a government policy announcement, he said: “We should copy the French. As I understand, if you live near a nuclear power station in France, you get free electricity and that’s great because then, I’ll have two in my garden if I get free electricity for my children as well.

“I think you want to recognise that things you do that are in the national interest, such as a state-owned generation company, must benefit those who make the sacrifice for the national interest.”

Earlier Mr Rees-Mogg stressed that he would like to see a simpler development consent process for new nuclear power plants to enable the next waves of reactors in the UK, amid concerns that Europe is losing nuclear power just when it really needs energy.

He said: “That’s a lot of regulation around that, as seen when nuclear plant plans collapsed in Wales and impacted the local economy. Did you know that Sizewell C will require 140 individual approvals from arms of the state, each one of which is potentially subject to judicial review.”

How the 787 uses electricity to maximise efficiency

Boeing 787 More-Electric Architecture replaces pneumatics with bleedless pressurization, VFSG starter-generators, electric brakes, and heated wing anti-ice, leveraging APU, RAT, batteries, and airport ground power for efficient, redundant electrical power distribution.

 

Key Points

An integrated, bleedless electrical system powering start, pressurization, brakes, and anti-ice via VFSGs, APU and RAT.

✅ VFSGs start engines, then generate 235Vac variable-frequency power

✅ Bleedless pressurization, electric anti-ice improve fuel efficiency

✅ Electric brakes cut hydraulic weight and simplify maintenance

 

The 787 Dreamliner is different to most commercial aircraft flying the skies today. On the surface it may seem pretty similar to the likes of the 777 and A350, but get under the skin and it’s a whole different aircraft.

When Boeing designed the 787, in order to make it as fuel efficient as possible, it had to completely shake up the way some of the normal aircraft systems operated. Traditionally, systems such as the pressurization, engine start and wing anti-ice were powered by pneumatics. The wheel brakes were powered by the hydraulics. These essential systems required a lot of physical architecture and with that comes weight and maintenance. This got engineers thinking.

What if the brakes didn’t need the hydraulics? What if the engines could be started without the pneumatic system? What if the pressurisation system didn’t need bleed air from the engines? Imagine if all these systems could be powered electrically… so that’s what they did.

 

Power sources

The 787 uses a lot of electricity. Therefore, to keep up with the demand, it has a number of sources of power, much as grid operators track supply on the GB energy dashboard to balance loads. Depending on whether the aircraft is on the ground with its engines off or in the air with both engines running, different combinations of the power sources are used.

 

Engine starter/generators

The main source of power comes from four 235Vac variable frequency engine starter/generators (VFSGs). There are two of these in each engine. These function as electrically powered starter motors for the engine start, and once the engine is running, then act as engine driven generators.

The generators in the left engine are designated as L1 and L2, the two in the right engine are R1 and R2. They are connected to their respective engine gearbox to generate electrical power directly proportional to the engine speed. With the engines running, the generators provide electrical power to all the aircraft systems.

 

APU starter/generators

In the tail of most commercial aircraft sits a small engine, the Auxiliary Power Unit (APU). While this does not provide any power for aircraft propulsion, it does provide electrics for when the engines are not running.

The APU of the 787 has the same generators as each of the engines — two 235Vac VFSGs, designated L and R. They act as starter motors to get the APU going and once running, then act as generators. The power generated is once again directly proportional to the APU speed.

The APU not only provides power to the aircraft on the ground when the engines are switched off, but it can also provide power in flight should there be a problem with one of the engine generators.

 

Battery power

The aircraft has one main battery and one APU battery. The latter is quite basic, providing power to start the APU and for some of the external aircraft lighting.

The main battery is there to power the aircraft up when everything has been switched off and also in cases of extreme electrical failure in flight, and in the grid context, alternatives such as gravity power storage are being explored for long-duration resilience. It provides power to start the APU, acts as a back-up for the brakes and also feeds the captain’s flight instruments until the Ram Air Turbine deploys.

 

Ram air turbine (RAT) generator

When you need this, you’re really not having a great day. The RAT is a small propeller which automatically drops out of the underside of the aircraft in the event of a double engine failure (or when all three hydraulics system pressures are low). It can also be deployed manually by pressing a switch in the flight deck.

Once deployed into the airflow, the RAT spins up and turns the RAT generator. This provides enough electrical power to operate the captain’s flight instruments and other essentials items for communication, navigation and flight controls.

 

External power

Using the APU on the ground for electrics is fine, but they do tend to be quite noisy. Not great for airports wishing to keep their noise footprint down. To enable aircraft to be powered without the APU, most big airports will have a ground power system drawing from national grids, including output from facilities such as Barakah Unit 1 as part of the mix. Large cables from the airport power supply connect 115Vac to the aircraft and allow pilots to shut down the APU. This not only keeps the noise down but also saves on the fuel which the APU would use.

The 787 has three external power inputs — two at the front and one at the rear. The forward system is used to power systems required for ground operations such as lighting, cargo door operation and some cabin systems. If only one forward power source is connected, only very limited functions will be available.

The aft external power is only used when the ground power is required for engine start.

 

Circuit breakers

Most flight decks you visit will have the back wall covered in circuit breakers — CBs. If there is a problem with a system, the circuit breaker may “pop” to preserve the aircraft electrical system. If a particular system is not working, part of the engineers procedure may require them to pull and “collar” a CB — placing a small ring around the CB to stop it from being pushed back in. However, on the 787 there are no physical circuit breakers. You’ve guessed it, they’re electric.

Within the Multi Function Display screen is the Circuit Breaker Indication and Control (CBIC). From here, engineers and pilots are able to access all the “CBs” which would normally be on the back wall of the flight deck. If an operational procedure requires it, engineers are able to electrically pull and collar a CB giving the same result as a conventional CB.

Not only does this mean that the there are no physical CBs which may need replacing, it also creates space behind the flight deck which can be utilised for the galley area and cabin.


 

 

A normal flight

While it’s useful to have all these systems, they are never all used at the same time, and, as the power sector’s COVID-19 mitigation strategies showed, resilience planning matters across operations. Depending on the stage of the flight, different power sources will be used, sometimes in conjunction with others, to supply the required power.

 

On the ground

When we arrive at the aircraft, more often than not the aircraft is plugged into the external power with the APU off. Electricity is the blood of the 787 and it doesn’t like to be without a good supply constantly pumping through its system, and, as seen in NYC electric rhythms during COVID-19, demand patterns can shift quickly. Ground staff will connect two forward external power sources, as this enables us to operate the maximum number of systems as we prepare the aircraft for departure.

Whilst connected to the external source, there is not enough power to run the air conditioning system. As a result, whilst the APU is off, air conditioning is provided by Preconditioned Air (PCA) units on the ground. These connect to the aircraft by a pipe and pump cool air into the cabin to keep the temperature at a comfortable level.

 

APU start

As we near departure time, we need to start making some changes to the configuration of the electrical system. Before we can push back , the external power needs to be disconnected — the airports don’t take too kindly to us taking their cables with us — and since that supply ultimately comes from the grid, projects like the Bruce Power upgrade increase available capacity during peaks, but we need to generate our own power before we start the engines so to do this, we use the APU.

The APU, like any engine, takes a little time to start up, around 90 seconds or so. If you remember from before, the external power only supplies 115Vac whereas the two VFSGs in the APU each provide 235Vac. As a result, as soon as the APU is running, it automatically takes over the running of the electrical systems. The ground staff are then clear to disconnect the ground power.

If you read my article on how the 787 is pressurised, you’ll know that it’s powered by the electrical system. As soon as the APU is supplying the electricity, there is enough power to run the aircraft air conditioning. The PCA can then be removed.


 

 

Engine start

Once all doors and hatches are closed, external cables and pipes have been removed and the APU is running, we’re ready to push back from the gate and start our engines. Both engines are normally started at the same time, unless the outside air temperature is  below 5°C.

On other aircraft types, the engines require high pressure air from the APU to turn the starter in the engine. This requires a lot of power from the APU and is also quite noisy. On the 787, the engine start is entirely electrical.

Power is drawn from the APU and feeds the VFSGs in the engines. If you remember from earlier, these fist act as starter motors. The starter motor starts the turn the turbines in the middle of the engine. These in turn start to turn the forward stages of the engine. Once there is enough airflow through the engine, and the fuel is igniting, there is enough energy to continue running itself.


 

 

After start

Once the engine is running, the VFSGs stop acting as starter motors and revert to acting as generators. As these generators are the preferred power source, they automatically take over the running of the electrical systems from the APU, which can then be switched off. The aircraft is now in the desired configuration for flight, with the 4 VFSGs in both engines providing all the power the aircraft needs.

As the aircraft moves away towards the runway, another electrically powered system is used — the brakes. On other aircraft types, the brakes are powered by the hydraulics system. This requires extra pipe work and the associated weight that goes with that. Hydraulically powered brake units can also be time consuming to replace.

By having electric brakes, the 787 is able to reduce the weight of the hydraulics system and it also makes it easier to change brake units. “Plug in and play” brakes are far quicker to change, keeping maintenance costs down and reducing flight delays.

 

In-flight

Another system which is powered electrically on the 787 is the anti-ice system. As aircraft fly though clouds in cold temperatures, ice can build up along the leading edge of the wing. As this reduces the efficiency of the the wing, we need to get rid of this.

Other aircraft types use hot air from the engines to melt it. On the 787, we have electrically powered pads along the leading edge which heat up to melt the ice.

Not only does this keep more power in the engines, but it also reduces the drag created as the hot air leaves the structure of the wing. A double win for fuel savings.

Once on the ground at the destination, it’s time to start thinking about the electrical configuration again. As we make our way to the gate, we start the APU in preparation for the engine shut down. However, because the engine generators have a high priority than the APU generators, the APU does not automatically take over. Instead, an indication on the EICAS shows APU RUNNING, to inform us that the APU is ready to take the electrical load.


 

 

Shutdown

With the park brake set, it’s time to shut the engines down. A final check that the APU is indeed running is made before moving the engine control switches to shut off. Plunging the cabin into darkness isn’t a smooth move. As the engines are shut down, the APU automatically takes over the power supply for the aircraft. Once the ground staff have connected the external power, we then have the option to also shut down the APU.

However, before doing this, we consider the cabin environment. If there is no PCA available and it’s hot outside, without the APU the cabin temperature will rise pretty quickly. In situations like this we’ll wait until all the passengers are off the aircraft until we shut down the APU.

Once on external power, the full flight cycle is complete. The aircraft can now be cleaned and catered, ready for the next crew to take over.

 

Bottom line

Electricity is a fundamental part of operating the 787. Even when there are no passengers on board, some power is required to keep the systems running, ready for the arrival of the next crew. As we prepare the aircraft for departure and start the engines, various methods of powering the aircraft are used.

The aircraft has six electrical generators, of which only four are used in normal flights. Should one fail, there are back-ups available. Should these back-ups fail, there are back-ups for the back-ups in the form of the battery. Should this back-up fail, there is yet another layer of contingency in the form of the RAT. A highly unlikely event.

The 787 was built around improving efficiency and lowering carbon emissions whilst ensuring unrivalled levels safety, and, in the wider energy landscape, perspectives like nuclear beyond electricity highlight complementary paths to decarbonization — a mission it’s able to achieve on hundreds of flights every single day.

Fire in manhole leaves thousands of Hydro-Québec customers without power

Montreal Power Outage linked to Hydro-Que9bec infrastructure after an underground explosion and manhole fire in Rosemont–La Petite–Patrie, disrupting the STM Blue Line and forcing strategic, cold-weather grid restoration on Be9langer Street.

 

Key Points

Outage from an underground blast and manhole fire disrupted STM service; Hydro-Que9bec restored the grid in cold weather.

✅ Peak impact: 41,000 customers; 10,981 still without power by 7:00 p.m.

✅ STM Blue Line restored after afternoon shutdown; Be9langer Street reopened.

✅ Hydro-Que9bec pacing restoration to avoid grid overload in cold weather.

 

Hydro-Québec says a power outage affecting Montreal is connected to an underground explosion and a fire in a manhole in Rosemont—La Petite–Patrie. 

The fire started in underground pipes belonging to Hydro-Québec on Bélanger Street between Boyer and Saint-André streets, according to Montreal firefighters, who arrived on the scene at 12:18 p.m.

The electricity had to be cut so that firefighters could get into the manhole where the equipment was located.

At the peak of the shutdown, nearly 41,000 customers were without power across Montreal.  As of 7:00 p.m., 10,981 clients still had no power.

In similar storms, Toronto power outages have persisted for hundreds, underscoring restoration challenges.

Hydro-Québec spokesperson Louis-Olivier Batty said the utility is being strategic about how it restores power across the grid. 

Because of the cold, and patterns seen during freezing rain outages, it anticipates that people will crank up the heat as soon as they get their electricity back, and that could trigger an overload somewhere else on the network, Batty said.

The Metro's Blue line was down much of the afternoon, but the STM announced the line was back up and running just after 4:30 p.m.

Bélanger Street was blocked to traffic much of the afternoon, however, it has now been reopened.

Batty said once the smoke clears, Hydro-Québec workers will take a look at the equipment to see what failed.

Adani Electricity's Power Supply Cuts in Mumbai

Adani Electricity Mumbai Power Cuts follow non-payment rules, reflecting billing disputes, regulatory compliance, consumer impact, and affordability concerns, while prompting mitigation measures like flexible payment plans, assistance programs, and clearer communication for residents.

 

Key Points

AEML cutoffs for unpaid bills per rules, raising affordability worries, billing issues, and calls for flexible aid.

✅ Triggered by unpaid bills under regulatory guidelines

✅ Affordability and billing transparency concerns raised

✅ Mitigation: flexible plans, aid for low-income users

 

Adani Electricity Mumbai Limited (AEML) recently made headlines by cutting power supply to around 100 homes in Mumbai, sparking discussions about the reasons behind this action and its implications for consumers, especially as reports like the Northeast D.C. outage continue to surface.

Background of the Incident

The power supply disconnections by AEML were reportedly due to non-payment of electricity bills by the affected households. This action, although necessary under AEML's policies and in accordance with regulatory guidelines, has raised concerns about the impact on residents, particularly during challenging economic times when pandemic electricity shut-offs highlighted energy insecurity.

Reasons for Non-Payment

Non-payment of electricity bills can stem from various reasons, including financial hardships, disputes over billing accuracy, or unforeseen circumstances affecting household finances. In Mumbai, where the cost of living is high, utility bills constitute a significant portion of monthly expenses for many households, mirroring trends of rising electricity bills seen elsewhere.

Regulatory and Legal Framework

AEML's decision to disconnect power supply aligns with regulatory provisions governing utility services, which may include emergency disconnection moratoriums in other jurisdictions. Utility companies are mandated to enforce bill payments to maintain operational sustainability and ensure fair distribution of resources among consumers.

Consumer Impact and Response

The power disconnections have prompted reactions from affected residents and consumer advocacy groups, highlighting issues related to affordability, transparency in billing practices, and the need for supportive measures during times of economic distress amid heat-related electricity struggles that pressure vulnerable households.

Mitigation Measures

In response to such incidents, utility companies and regulatory authorities often implement mitigation measures. These may include flexible payment options, financial assistance programs for low-income households, and enhanced communication about billing procedures and payment deadlines, along with policy scrutiny such as utility spending oversight to curb unnecessary costs.

Future Considerations

As cities like Mumbai continue to grow and face challenges related to urbanization and infrastructure development, ensuring reliable and affordable access to essential services like electricity, including efforts to prevent summer power outages, remains a priority. Balancing the operational needs of utility providers with consumer welfare concerns requires ongoing dialogue and proactive measures from all stakeholders.

Conclusion

The power supply cuts by Adani Electricity in Mumbai underscore the complexities of managing utility services in urban centers. While necessary for financial viability and regulatory compliance, such actions also highlight broader issues of affordability and consumer protection. Moving forward, collaborative efforts between utility companies, regulatory authorities, and community stakeholders are essential in addressing these challenges and ensuring equitable access to essential services for all residents.
