Zimbabwe's already dim electricity supply faces a new threat, as the country's main power plant says it needs to dig for new coal reserves under a river inside a national park to keep running.
Hwange Colliery says it only has enough coal to power its 940 megawatt plant for three more years.
Shortages of coal and working capital, as well as ageing and broken equipment, have already forced the shutdown of three smaller power stations across Zimbabwe, causing daily blackouts that have plagued the country for years.
The company says its only viable new deposits of coal suitable for power generation lie in the heart of the Hwange national park, under a river that supplies nearby towns — including the world-famous Victoria Falls — as well as thousands of endangered animals.
Accessing the new coal would mean strip mining one of the environmentally delicate region's few water supplies.
"The coal is submerged under water, so we have to find ways of de-watering the adjacent rivers in the area," Fred Moyo, the company's managing director, told AFP.
"We only have three years left of power coal although initial indications were that we have power coal that would take us at least another 15 years."
De-watering would shift the flow of rivers to allow access to the coal, but in the process will create huge pools of polluted water.
Hwange national park covers an area half the size of Switzerland on the edge of the Kalahari, where every drop of water is valuable. It's also home to all of Zimbabwe's endangered species, including 45,000 elephants.
Existing mines still have plenty of industrial-grade coal, but that variety burns so hot that it would overheat the generators, Moyo said.
Lovemore Mungwashu, operations coordinator for WWF, said mining the new coal reserves would pose huge problems for the region.
"Our greatest concern is how Hwange will put in place measures that will affect not only the wildlife, but communities within town," he told AFP.
"Hwange Colliery should first address how it going to handle the issue of contaminated water before it starts any underground mining and de-watering plans," he said.
Zimbabwe also has the 750 megawatt Kariba hydro-power dam, but it suffers chronic breakdowns due to a lack of spare parts and expertise, adding to pressure on Hwange.
"Hwange Colliery's role in the economy of Zimbabwe is of great strategic importance, as coal is a vital source of energy in a country where hydro-electrical power generation has perennially broken down," Moyo said.
Since President Robert Mugabe and his rival Prime Minister Morgan Tsvangirai formed a unity government in February, the economy has slowly started to mend after a decade of collapse.
Industrial activity has been rising since the local currency was abandoned in January, but growth is limited by the scant power supply, and many industries are operating at only 10 percent of their capacity.
Zimbabwe spends millions of dollars importing electricity from its neighbours, just to keep the lights on some of the time in parts of the country, which at times goes for 15 to 20 hours without electricity.
Hwange Colliery is looking at other options, including setting up a methane gas plant that would burn fewer carbon emissions than coal and prevent the need for more mining, Moyo said.
But that would require a 10 million dollar investment, money which Zimbabwe doesn't have. Moyo said the company has lined up possible partners, but is still waiting for government approval for the project.
Alberta Energy Price Spike signals rising electricity and natural gas costs; lock in fixed rates as storage is low, demand surged in heat waves, and exports rose after Hurricane Ida, driving volatility and higher futures.
Key Points
An anticipated surge in Alberta electricity and natural gas prices, urging consumers to lock fixed rates to reduce risk.
✅ Fixed-rate gas near $3.79/GJ vs futures approaching $6/GJ
✅ Low storage after heat waves and U.S. export demand
✅ Switch providers or plans; UCA comparison tool helps
Energy economists are warning Albertans to review their gas and electricity bills and lock in a fixed rate if they haven't already done so because prices are expected to spike in the coming months.
"I have been urging anyone who will listen that every single Albertan should be on a fixed rate for this winter," University of Calgary energy economist Blake Shaffer said Monday. "And I say that for both natural gas and power."
Shaffer said people will rightly point out energy costs make up only roughly a third of their monthly bill. The rest of the costs for such things as delivery fees can't be avoided.
But, he said, "there is an energy component and it is meaningful in terms of savings."
For example, Shaffer said, when he checked last week, a consumer could sign a fixed rate gas contract for $3.79 a gigajoule and the current future price for gas is nearly $6 a gigajoule.
A typical household would use about 15 gigajoules a month, he said, so a consumer could save $30 to $45 a month for five months. For people on lower or fixed incomes, "that is a pretty significant saving."
Comparable savings can also be achieved with electricity, he said.
Shaffer said research has shown households that are least able to afford sharp increases in gas and electrical bills are less likely to pick up the phone and call their energy provider and either negotiate a lower fixed rate contract or jump to a new provider.
But, he said, it is definitely worth the time and effort, particularly as Calgary electricity bills are rising across the city. Alberta's Utilities Consumer Advocate has a handy cost comparison tool on its website that allows consumers to conduct regional price comparisons that will assist in making an informed decision.
"Folks should know that for most providers you can change back to a floating rate any time you want," Shaffer said.
Summer heat wave affected natural gas supply Why are energy prices set to spike in Alberta, which is a major producer of natural gas?
Sophie Simmonds, managing director of the brokerage firm Anova Energy, said Alberta is now generating the majority of its power using natural gas.
The heat wave in June and July created record electrical demand. Normally, natural gas is stored in the summer for use in the winter. But this year, there was much greater gas consumption in the summer and so less was stored.
On top of that, Alberta has been exporting much more natural gas to the United States since August and September because Hurricane Ida knocked out natural gas assets in the Gulf of Mexico.
"So what this means is we are actually going into winter with very, very low storage numbers," Simmonds said.
Why natural gas prices have surged to some of their highest levels in years Canadians to remain among world's top energy users even as government strives for net zero Consultant Matt Ayres said he believes rising electricity prices also are being affected by Alberta's transition from carbon-intensive fuel sources to less carbon-intensive fuel sources.
"That transition is not always smooth," said Ayres, who is also an adjunct assistant professor at the University of Calgary's School of Public Policy.
"It is my view that at least some of the price increases we are seeing on electricity comes down to difficulties imposed by that transition and also by a reduction in competition amongst generators, as well as power market overhaul debates shaping policy."
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.
India Solar Slowdown and Coal Surge highlights policy uncertainty, grid stability concerns, financing gaps, and land acquisition issues affecting renewable energy, emissions targets, energy security, storage deployment, and tendering delays across the solar value chain.
Key Points
Analysis of slowed solar growth and rising coal in India, examining policy, grid, finance, and emissions tradeoffs.
✅ Policy uncertainty and tender delays stall solar pipelines
✅ Grid bottlenecks, storage gaps, and curtailment risks persist
✅ Financing strains and DISCOM payment delays dampen investment
India, a global leader in renewable energy adoption where renewables surpassed coal in capacity recently, faces a pivotal moment as the growth of solar power output decelerates while coal generation sees an unexpected surge. This article examines the factors contributing to this shift, its implications for India's energy transition, and the challenges and opportunities it presents.
India's Renewable Energy Ambitions
India has set ambitious targets to expand its renewable energy capacity, including a goal to achieve 175 gigawatts (GW) of renewable energy by 2022, with a significant portion from solar power. Solar energy has been a focal point of India's renewable energy strategy, as documented in on-grid solar development studies, driven by falling costs, technological advancements, and environmental imperatives to reduce greenhouse gas emissions.
Factors Contributing to Slowdown in Solar Power Growth
Despite initial momentum, India's solar power growth has encountered several challenges that have contributed to a slowdown. These include policy uncertainties, regulatory hurdles, land acquisition issues, and financial constraints affecting project development and implementation, even as China's solar PV growth surged in recent years. Delays in tendering processes, grid connectivity issues, and payment delays from utilities have also hindered the expansion of solar capacity.
Surge in Coal Generation
Concurrently, India has witnessed an unexpected increase in coal generation in recent years. Coal continues to dominate India's energy mix, accounting for a significant portion of electricity generation due to its reliability, affordability, and existing infrastructure, even as wind and solar surpassed coal in the U.S. in recent periods. The surge in coal generation reflects the challenges in scaling up renewable energy quickly enough to meet growing energy demand and address grid stability concerns.
Implications for India's Energy Transition
The slowdown in solar power growth and the rise in coal generation pose significant implications for India's energy transition and climate goals. While renewable energy remains central to India's long-term energy strategy, and as global renewables top 30% of electricity generation worldwide, the persistence of coal-fired power plants complicates efforts to reduce carbon emissions and mitigate climate change impacts. Balancing economic development, energy security, and environmental sustainability remains a complex challenge for policymakers.
Challenges and Opportunities
Addressing the challenges facing India's solar sector requires concerted efforts to streamline regulatory processes, improve grid infrastructure, and enhance financial mechanisms to attract investment. Encouraging greater private sector participation, promoting technology innovation, and expanding renewable energy storage capacity are essential to overcoming barriers and accelerating solar power deployment, as wind and solar have doubled their global share in recent years, demonstrating the pace possible.
Policy and Regulatory Framework
India's government plays a crucial role in fostering a conducive policy and regulatory framework to support renewable energy growth and phase out coal dependence, particularly as renewable power is set to shatter records worldwide. This includes implementing renewable energy targets, providing incentives for solar and other clean energy technologies, and addressing systemic barriers that hinder renewable energy adoption.

PJM and MISO Electricity-Market Reforms promise consumer savings by enabling renewables, wind, solar, and storage participation in wholesale markets, enhancing grid flexibility, reliability services, and real-time pricing across the Midwest, Great Lakes, and Mid-Atlantic.
Key Points
Market rule updates enabling renewables and storage, improving reliability and lowering consumer costs.
✅ Removes barriers to renewables, storage, demand response
✅ Improves intermarket links and real-time price signals
✅ Rewards flexible resources and reliability services
Electricity-market reforms to enable more renewables generation and storage in the Midwest, Great Lakes, and Mid-Atlantic could save consumers in the US and Canada more than $6.9 billion a year, according to a new report.
The findings may have major implications for consumer groups, large industrial companies, businesses, and homeowners in those regions, said the Wind-Solar Alliance, (WSA), which commissioned the Customer Focused and Clean report.
The WSA is a non-profit organisation supporting the growth of renewables. American Wind Energy Association CEO Tom Kiernan is listed as WSA secretary, amid ongoing debates about the US wind market today.
"Consumers are looking for clean energy, affordable and reliable energy that will keep their monthly electricity bills low," said Kristin Munsch, president of the Board of the Consumer Advocates of the PJM States, which represents over 65 million consumers in 13 states.
"There is great potential to achieve those goals with the cost-effective integration of wind, solar and battery storage plants into our wholesale power markets."
The report found the average residential customer in the PJM and Midcontinent Independent System Operator (MISO) regions, covering 29 US states and the Canadian province of Manitoba, could each save up to $48 a year as lower wholesale electricity prices materialize with significantly more wind, solar and storage on the grid.
The average annual home electricity, for example in New Jersey, in the PJM region, was just over $106 in 2018, according to the US Energy Information Administration.
The latest report quantifies the findings of a previous one for the WSA, published in November 2018, which found that outdated wholesale market rules in the US were preventing full participation by renewable energy, including wind power.
Outdated rules
"The existing wholesale power market rules were largely developed for slower-to-react conventional generators, such as coal and nuclear plants," said Michael Milligan, president of Milligan Grid Solutions and co-author of the new report.
"This report demonstrates the benefits of updating the rules to better accommodate the characteristics and potential contributions of wind and solar and other newer sources of low-cost generation."
With more renewables generation on the grid, customers would benefit the most from increasing power-system flexibility through market structures, the new report concluded. It called for the removal of artificial barriers preventing renewables, storage and demand response from participating in markets.
The report also advocated improving the connections between markets, thereby lowering transaction costs of imports and exports between neighbouring systems.
"There are currently artificial barriers that are preventing the full participation of renewables, storage and other new technologies in the PJM and MISO markets," said Michael Goggin, vice president of Grid Strategies and co-author of the report.
"Providing consumers with a real-time price signal that allows them to adjust their demand, rewarding flexible resources for their capabilities through improved market design, and allowing renewable and storage resources to participate in reliability-services markets would yield the greatest consumer benefits," he said.
PJM and MISO, which incorporate some of the windiest areas of the country, are currently reviewing their market designs as part of a broader grid overhaul underway.
Advanced Nuclear Reactors drive U.S. clean energy with small modular reactors, a new test facility at Idaho National Laboratory, and public-private partnerships accelerating nuclear innovation, safety, and cost reductions through DOE-backed programs and university simulators.
Key Points
Advanced nuclear reactors are next-gen designs, including SMRs, offering safer, cheaper, low-carbon power.
✅ DOE test facility at Idaho National Laboratory
✅ Small modular reactors with passive safety systems
✅ University simulators train next-gen nuclear operators
Energy Secretary Rick Perry is advancing plans to shift the United States towards next-gen nuclear power reactors.
The Energy Department announced this week it has launched a new test facility at the Idaho National Laboratory where private companies can work on advanced nuclear technologies, as the first new U.S. reactor in nearly seven years starts up, to avoid the high costs and waste and safety concerns facing traditional nuclear power plants.
“[The National Reactor Innovation Center] will enable the demonstration and deployment of advanced reactors that will define the future of nuclear energy,” Perry said.
With climate change concerns growing and net-zero emissions targets emerging, some Republicans and Democrats are arguing for the need for more nuclear reactors to feed the nation’s electricity demand. But despite nuclear plants’ absence of carbon emissions, the high cost of construction, questions around what to do with the spent nuclear rods and the possibility of meltdown have stymied efforts.
A new generation of firms, including Microsoft founder Bill Gates’ Terra Power venture, are working on developing smaller, less expensive reactors that do not carry a risk of meltdown.
“The U.S. is on the verge of commercializing groundbreaking nuclear innovation, and we must keep advancing the public-private partnerships needed to traverse the dreaded valley of death that all too often stifles progress,” said Rich Powell, executive director of ClearPath, a non-profit advocating for clean energy and green industrial strategies worldwide.
The new Idaho facility is budgeted at $5 million under next year’s federal budget, even as the cost of U.S. nuclear generation has fallen to a ten-year low, which remains under negotiation in Congress.
On Thursday another advanced nuclear developer working on small modular systems, Oregon-based NuScale Power, announced it was building three virtual nuclear control rooms at Texas A&M University, Oregon State University and the University of Idaho, with funding from the Energy Department.
The simulators will be open to researchers and students, to train on the operation of smaller, modular reactors, as well as the general public.
NuScale CEO John Hopkins said the simulators would “help ensure that we educate future generations about the important role nuclear power and small modular reactor technology will play in attaining a safe, clean and secure energy future for our country.”
