Germany's Merck KGaA expects televisions based on organic light-emitting diodes (OLED) to complement but not replace liquid crystal technology in an $82 billion market dominated by LCD and plasma.
Energy-efficient OLED panels make for thin and light displays. They offer crisp pictures and are good at showing fast-moving images common in sports events and action movies.
But making large OLED screens has proved difficult.
Proponents have hoped they could potentially replace liquid crystal display (LCD) and plasma TVs.
"The reality is that OLED will come one day as an additional technology for flat displays. I say this with a lot of confidence," the head of Merck's chemicals business, Walter Zywottek, told Reuters in an interview.
Merck, the world's largest supplier of liquid crystals for use in TVs, notebook and mobile phones, dominates the high-tech niche industry with about two thirds of the liquid crystal market.
Top LCD makers such as Samsung Electronics, LG Philips LCD, Sharp Corp. and AU Optronics are its customers.
The LCD makers have invested about $82 billion in plant capacity over the past 11 years. In 2008, some $28 billion in new investments has been announced. In contrast, plasma screen makers invested about $12 billion over the last decade.
"Forget replacement. Delete replacement from your vocabulary, it's not going to happen. Would you be spending so much money if you were thinking about replacement?" he asked.
He said any serious commercial OLED application would not arrive before 2010.
Zywottek said Merck is also boosting its investment in OLED but is not expecting it to play the role that liquid crystals now have at the company.
"It will not be one dominating supplier in OLED. Not a single supplier will have such a strong position as we have in liquid crystals," he said.
"There will be different companies with different materials and we will be one of them," he added.
Zywottek said more than 100 researchers have been working on OLED technology for a couple of years at Merck.
Merck announced it is investing 47 million euros in a new research and development centre at its Darmstadt headquarters for the chemicals business, including for OLED.
This is its largest single investment to date in chemicals research and development.
Sony Corp. showcased its OLED TVs this year and will start selling an 11-inch version of the 3-millimeter thick TV for about $2,000.
NuScale SMR Design Certification marks NRC Phase 6 FSER approval, validating small modular reactor safety and design review, enabling UAMPS deployment at Idaho National Laboratory and advancing DOE partnerships and Canadian vendor assessments.
Key Points
It is the NRC FSER approval confirming NuScale SMR safety design, enabling licensed deployment and vendor reviews.
✅ 60 MW modules, up to 12 per plant; UAMPS project at Idaho National Laboratory
US-based NuScale Power announced on 28 August that the US Nuclear Regulatory Commission (NRC) had completed Phase 6 review—the last and final phase—of the Design Certification Application (DCA) for its small modular reactor (SMR) with the issuance of the Final Safety Evaluation Report (FSER).
The FSER represents completion of the technical review and approval of the NuScale SMR design. With this final phase of NuScale’s DCA now complete, customers can proceed with plans to develop NuScale power plants as Ontario breaks ground on first SMR projects advance, with the understanding that the NRC has approved the safety aspects of the NuScale design.
“This is a significant milestone not only for NuScale, but also for the entire US nuclear sector and the other advanced nuclear technologies that will follow,” said NuScale chairman and CEO John Hopkins.
“The approval of NuScale’s design is an incredible accomplishment and we would like to extend our deepest thanks to the NRC for their comprehensive review, to the US Department of Energy (DOE) for its continued commitment to our successful private-public partnership to bring the country’s first SMR to market, and to the many other individuals who have dedicated countless hours to make this extraordinary moment a reality,” he added. “Additionally, the cost-shared funding provided by Congress over the past several years has accelerated NuScale’s advancement through the NRC Design Certification process.”
NuScale’s design certification application was accepted by the NRC in March 2017. NuScale spent over $500 million, with the backing of Fluor, and over 2 million hours to develop the information needed to prepare its DCA application, an effort that, similar to Rolls-Royce’s MoU with Exelon, underscores private-sector engagement to advance nuclear innovation. The company also submitted 14 separate Topical Reports in addition to the over 12,000 pages for its DCA application and provided more than 2 million pages of supporting information for NRC audits.
NuScale’s SMR is a fully factory-fabricated, 60MW power module based on pressurised water reactor technology. The scalable design means a power plant can house up to 12 individual power modules, and jurisdictions like Ontario have announced plans for four SMRs at Darlington to leverage modularity.
The NuScale design is so far the only small modular reactor to undergo a design certification review by the NRC, while in the UK UK approval for Rolls-Royce SMR is expected by mid-2024, signaling parallel regulatory progress. The design certification process addresses the various safety issues associated with the proposed nuclear power plant design, independent of a specific site and is valid for 15 years from the date of issuance.
NuScale's first customer, Utah Associated Municipal Power Systems (UAMPS), is planning a 12-module SMR plant at a site at the Idaho National Laboratory as efforts like TerraPower's molten-salt mini-reactor advance in parallel. Construction was scheduled to start in 2023, with the first module expected to begin operation in 2026. However, UAMPS has informed NuScale it needs to push back the timeline for operation of the first module from 2026 to 2029, the Washington Examiner reported on 24 August.
The NuScale SMR is also undergoing a vendor design review with the Canadian Nuclear Safety Commission, amid provincial activity such as New Brunswick's SMR debate that highlights domestic interest. NuScale has signed agreements with entities in the USA, Canada, Romania, the Czech Republic, and Jordan.
✅ Stronger oversight sought to curb waste and boost transparency.
California residents and consumer groups are demanding relief as their electricity bills continue to climb, putting increasing pressure on state regulators to intervene. A recent op-ed in the San Francisco Chronicle highlights the growing frustration, emphasizing that California already has some of the highest electricity rates in the country, as coverage on why prices are soaring underscores, and these costs are only getting more burdensome.
Factors Driving High Bills
The rising electricity bills are attributed to several factors:
Wildfire Mitigation and Liability: Utility companies are investing heavily in wildfire prevention measures, such as vegetation management and infrastructure hardening. The costs of these initiatives, along with the increasing financial liabilities associated with wildfire risk, are being passed on to consumers.
Transmission Costs: California's vast geography and move towards renewable energy sources necessitate significant investments in transmission lines to deliver electricity from remote locations. These infrastructure costs also contribute to higher bills.
Aging Infrastructure: California's electricity grid is aging and requires upgrades and maintenance, and the expenses associated with these efforts are reflected in consumer rates.
Proposed Solutions and Debates
Consumer advocates and some lawmakers are calling for various actions to address the issue, including a potential revamp of electricity rates to clean the grid:
Fixed Charge Proposal: The California Public Utilities Commission (CPUC) is considering a proposal to introduce an income-based fixed charge on electricity bills. This change aims to make rates more predictable and encourage investment in renewable energy sources. However, opponents argue that it could disproportionately impact low-income households and discourage conservation.
Utility Profit Caps: Some advocate for capping utility companies' profits. They believe excessive profits should be returned to customers in the form of lower rates. However, utility companies counter that they need a certain level of profit to invest in infrastructure and maintain a reliable grid.
Increased Oversight: Consumer groups are calling for stricter oversight of utility company spending, and legislators are preparing to crack down on utility spending through upcoming votes as well. They demand transparency and want to ensure that funds collected from customers are being used for necessary investments and not for lobbying or excessive executive compensation.
Comparisons and National Implications
Similar concerns about rising utility bills are emerging in other parts of the country as more states transition to renewable energy and invest in infrastructure upgrades.
A report by the Energy Information Administration (EIA) shows that average residential electricity rates across the country have been on the rise for the past decade. While California currently ranks amongst the highest, major changes to electric bills are being debated, and other states are following suit, demonstrating the nationwide challenge of balancing affordability with necessary investments.
Uncertain Future
The California Public Utilities Commission is reviewing the fixed charge proposal and is expected to make a decision later this year, with income-based flat-fee utility bills moving closer in the process. The outcome of this decision and potential additional regulatory changes will have significant ramifications for California residents, and some lawmakers plan to overturn income-based charges if adopted, which could set a precedent for how other states handle the rising costs associated with the energy transition.
Hydrogen Fuel Cell Crane Port of Vancouver showcases zero-emission RTG technology by DP World, TCA Electric, and partners, using hydrogen-electric fuel cells, battery energy storage, and regenerative capture to decarbonize container handling operations.
Key Points
A retrofitted RTG crane powered by hydrogen fuel cells, batteries, and regeneration to cut diesel use and CO2 emissions.
✅ Dual fuel cell system charges high-voltage battery
✅ Regenerative capture reduces energy demand and cost
✅ Pilot targets zero-emission RTG fleets by 2040
In a groundbreaking move toward sustainable logistics, TCA Electric, a Chilliwack-based industrial electrical contractor, is at the forefront of a pioneering hydrogen fuel cell crane project at the Port of Vancouver. This initiative, led by DP World in collaboration with TCA Electric and other partners, marks a significant step in decarbonizing port operations and showcases the potential of hydrogen technology in heavy-duty industrial applications.
A Vision for Zero-Emission Ports
The Port of Vancouver, Canada's largest port, has long been a hub for international trade. However, its operations have also contributed to substantial greenhouse gas emissions, even as DP World advances an all-electric berth in the U.K., primarily from diesel-powered Rubber-Tired Gantry (RTG) cranes. These cranes are essential for container handling but are significant sources of CO₂ emissions. At DP World’s Vancouver terminal, 19 RTG cranes account for 50% of diesel consumption and generate over 4,200 tonnes of CO₂ annually.
To address this, the Vancouver Fraser Port Authority and the Province of British Columbia have committed to transforming the port into a zero-emission facility by 2050, supported by provincial hydrogen investments that accelerate clean energy infrastructure across B.C. This ambitious goal has spurred several innovative projects, including the hydrogen fuel cell crane pilot.
TCA Electric’s Role in the Hydrogen Revolution
TCA Electric's involvement in this project underscores its expertise in industrial electrification and commitment to sustainable energy solutions. The company has been instrumental in designing and implementing the electrical systems that power the hydrogen fuel cell crane. This includes integrating the Hydrogen-Electric Generator (HEG), battery energy storage system, and regenerative energy capture technologies. The crane operates using compressed gaseous hydrogen stored in 15 pressurized tanks, which feed a dual fuel cell system developed by TYCROP Manufacturing and H2 Portable. This system charges a high-voltage battery that powers the crane's electric drive, significantly reducing its carbon footprint.
The collaboration between TCA Electric, TYCROP, H2 Portable, and HTEC represents a convergence of local expertise and innovation. These companies, all based in British Columbia, have leveraged their collective knowledge to develop a world-first solution in the industrial sector, while regional pioneers like Harbour Air's electric aircraft illustrate parallel progress in aviation. TCA Electric's leadership in this project highlights its role as a key enabler of the province's clean energy transition.
Demonstrating Real-World Impact
The pilot project began in October 2023 with the retrofitting of a diesel-powered RTG crane. The first phase included integrating the hydrogen-electric system, followed by a one-year field trial to assess performance metrics such as hydrogen consumption, energy generation, and regenerative energy capture rates. Early results have been promising, with the crane operating efficiently and emitting only steam, compared to the 400 kilograms of CO₂ produced by a comparable diesel unit.
If successful, this project could serve as a model for decarbonizing port operations worldwide, mirroring investments in electric trucks at California ports that target landside emissions. DP World plans to consider converting its fleet of RTG cranes in Vancouver and Prince Rupert to hydrogen power, aligning with its global commitment to achieve carbon neutrality by 2040.
Broader Implications for the Industry
The success of the hydrogen fuel cell crane pilot at the Port of Vancouver has broader implications for the shipping and logistics industry. It demonstrates the feasibility of transitioning from diesel to hydrogen-powered equipment in challenging environments, and aligns with advances in electric ships on the B.C. coast. The project's success could accelerate the adoption of hydrogen technology in other ports and industries, contributing to global efforts to reduce carbon emissions and combat climate change.
Moreover, the collaboration between public and private sectors in this initiative sets a precedent for future partnerships aimed at advancing clean energy solutions. The support from the Province of British Columbia, coupled with the expertise of companies like TCA Electric and utility initiatives such as BC Hydro's vehicle-to-grid pilot underscore the importance of coordinated efforts in achieving sustainability goals.
Looking Ahead
As the field trial progresses, stakeholders are closely monitoring the performance of the hydrogen fuel cell crane. The data collected will inform decisions on scaling the technology and integrating it into broader port operations. The success of this project could pave the way for similar initiatives in other regions, complementing the province's move to electric ferries with CIB support, promoting the widespread adoption of hydrogen as a clean energy source in industrial applications.
TCA Electric's leadership in this project exemplifies the critical role of skilled industrial electricians in driving the transition to sustainable energy solutions. Their expertise ensures the safe and efficient implementation of complex systems, making them indispensable partners in the journey toward a zero-emission future.
The hydrogen fuel cell crane pilot at the Port of Vancouver represents a significant milestone in the decarbonization of port operations. Through innovative partnerships and local expertise, this project is setting the stage for a cleaner, more sustainable future in global trade and logistics.
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.
SaskPower Summer Power Demand Record hits 3,520 MW as heat waves drive electricity consumption; grid capacity, renewables expansion, and energy efficiency tips highlight efforts to curb greenhouse gas emissions while meeting Saskatchewan's growing load.
Key Points
The latest summer peak load in Saskatchewan: 3,520 MW, driven by heat, with plans to expand capacity and lower emissions.
✅ New peak surpasses last August by 50 MW to 3,520 MW.
✅ Capacity target: 7,000 MW by 2030 with more renewables.
✅ Tips: AC settings, close blinds, delay heat-producing chores.
As the mercury continues to climb in Saskatchewan, where Alberta's summer electricity record offers a regional comparison, SaskPower says the province has set a new summer power demand record.
The Crown says the new record is 3,520 megawatts. It’s an increase of 50 megawatts over the previous record, or enough electricity for 50,000 homes.
“We’ve seen both summer and winter records set every year for a good while now. And if last summer is any indication, we could very well see another record before temperatures cool off heading into the fall,” said SaskPower Vice President of Transmission and Industrial Services Kory Hayko in a written release. “It’s not impossible we’ll break this record again in the coming days. It’s SaskPower’s responsibility to ensure that Saskatchewan people and businesses have the power they need to thrive. That’s what drives our investment of $1 billion every year, as outlined in our annual report, to modernize and grow the province’s electrical system.”
The previous summer consumption record of 3,740 megawatts was set last August, and similar extremes in the Yukon electricity demand highlight broader demand pressures this year. The winter demand record remains higher at 3,792 megawatts, set on Dec. 29, 2017.
SaskPower says it plans to expand its generation capacity from 4,500 megawatts now to 7,000 megawatts in 2030, with a focus on decreasing greenhouse gas emissions and doubling renewable electricity by 2030 as part of its strategy.
To reduce power bills, the Crown suggests turning down or programming air conditioning when residents aren’t home, inspecting the air conditioner to make sure it is operating efficiently, keeping blinds closed to keep out direct sunlight, delaying chores that produce heat and making sure electronics are turned off when people leave the room.
The new record beats the previous summer peak of 3,470 MW, set last August after also being broken twice in July. The winter demand record is still higher at 3,792 MW, which was set on December 29, 2017. To meet growing power demand, and amid projections that Manitoba's electrical demand could double in the next 20 years, SaskPower is expanding its generation capacity from approximately 4,500 MW now to 7,000 MW by 2030 while also reducing greenhouse gas emissions by 40 per cent from 2005 levels. To accomplish this, we will be significantly increasing the amount of renewables on our system.
Cooling and heating represents approximately a quarter of residential power bills. To reduce consumption and power bills during heat waves, SaskPower’s customers can:
Turn down or program the air conditioning when no one is home (for every degree that air conditioning is lowered for an eight-hour period, customers can save up to two per cent on their power costs);
Consider having their air conditioning unit inspected to make sure it is operating efficiently;
Keep the heat out by closing blinds and drapes, especially those with direct sunlight;
Delay chores that produce heat and moisture, like dishwashing and laundering, until the cooler parts of the day or evening; and
As with any time of the year, make sure lights, televisions and other electronics are turned off when no one's in the room. For example, a modern gaming console can use as much power as a refrigerator.
Hourly Electricity Emissions Tracking maps grid balancing areas, embodied emissions, and imports/exports, revealing carbon intensity shifts across PJM, ERCOT, and California ISO, and clarifying renewable energy versus coal impacts on health and climate.
Key Points
An hourly method tracing generation, flows, and embodied emissions to quantify carbon intensity across US balancing areas.
✅ Hourly traces of imports/exports and generation mix
✅ Consumption-based carbon intensity by balancing area
✅ Policy insights for renewables, coal, health costs
In the United States, electricity generation accounts for nearly 30% of our carbon emissions. Some states have responded to that by setting aggressive renewable energy standards; others are hoping to see coal propped up even as its economics get worse. Complicating matters further is the fact that many regional grids are integrated, and as America goes electric the stakes grow, meaning power generated in one location may be exported and used in a different state entirely.
Tracking these electricity exports is critical for understanding how to lower our national carbon emissions. In addition, power from a dirty source like coal has health and environment impacts where it's produced, and the costs of these aren't always paid by the parties using the electricity. Unfortunately, getting reliable figures on how electricity is produced and where it's used is challenging, even for consumers trying to find where their electricity comes from in the first place, leaving some of the best estimates with a time resolution of only a month.
Now, three Stanford researchers—Jacques A. de Chalendar, John Taggart, and Sally M. Benson—have greatly improved on that standard, and they have managed to track power generation and use on an hourly basis. The researchers found that, of the 66 grid balancing areas within the United States, only three have carbon emissions equivalent to our national average, and they have found that imports and exports of electricity have both seasonal and daily changes. de Chalendar et al. discovered that the net results can be substantial, with imported electricity increasing California's emissions/power by 20%.
Hour by hour To figure out the US energy trading landscape, the researchers obtained 2016 data for grid features called balancing areas. The continental US has 66 of these, providing much better spatial resolution on the data than the larger grid subdivisions. This doesn't cover everything—several balancing areas in Canada and Mexico are tied in to the US grid—and some of these balancing areas are much larger than others. The PJM grid, serving Pennsylvania, New Jersey, and Maryland, for example, is more than twice as large as Texas' ERCOT, in a state that produces and consumes the most electricity in the US.
Despite these limitations, it's possible to get hourly figures on how much electricity was generated, what was used to produce it, and whether it was used locally or exported to another balancing area. Information on the generating sources allowed the researchers to attach an emissions figure to each unit of electricity produced. Coal, for example, produces double the emissions of natural gas, which in turn produces more than an order of magnitude more carbon dioxide than the manufacturing of solar, wind, or hydro facilities. These figures were turned into what the authors call "embodied emissions" that can be traced to where they're eventually used.
Similar figures were also generated for sulfur dioxide and nitrogen oxides. Released by the burning of fossil fuels, these can both influence the global climate and produce local health problems.
Huge variation The results were striking. "The consumption-based carbon intensity of electricity varies by almost an order of magnitude across the different regions in the US electricity system," the authors conclude. The low is the Bonneville Power grid region, which is largely supplied by hydropower; it has typical emissions below 100kg of carbon dioxide per megawatt-hour. The highest emissions come in the Ohio Valley Electric region, where emissions clear 900kg/MW-hr. Only three regional grids match the overall grid emissions intensity, although that includes the very large PJM (where capacity auction payouts recently fell), ERCOT, and Southern Co balancing areas.
Most of the low-emissions power that's exported comes from the Pacific Northwest's abundant hydropower, while the Rocky Mountains area exports electricity with the highest associated emissions. That leads to some striking asymmetries. Local generation in the hydro-rich Idaho Power Company has embodied emissions of only 71kg/MW-hr, while its imports, coming primarily from Rocky Mountain states, have a carbon content of 625kg/MW-hr.
The reliance on hydropower also makes the asymmetry seasonal. Local generation is highest in the spring as snow melts, but imports become a larger source outside this time of year. As solar and wind can also have pronounced seasonal shifts, similar changes will likely be seen as these become larger contributors to many of these regional grids. Similar things occur daily, as both demand and solar production (and, to a lesser extent, wind) have distinct daily profiles.
The Golden State California's CISO provides another instructive case. Imports represent less than 30% of its total electric use in 2016, yet California electricity imports provided 40% of its embodied emissions. Some of these, however, come internally from California, provided by the Los Angeles Department of Water and Power. The state itself, however, has only had limited tracking of imported emissions, lumping many of its sources as "other," and has been exporting its energy policies to Western states in ways that shape regional markets.
Overall, the 2016 inventory provides a narrow picture of the US grid, as plenty of trends are rapidly changing our country's emissions profile, including the rise of renewables and the widespread adoption of efficiency measures and other utility trends in 2017 that continue to evolve. The method developed here can, however, allow for annual updates, providing us with a much better picture of trends. That could be quite valuable to track things like how the rapid rise in solar power is altering the daily production of clean power.
More significantly, it provides a basis for more informed policymaking. States that wish to promote low-emissions power can use the information here to either alter the source of their imports or to encourage the sites where they're produced to adopt more renewable power. And those states that are exporting electricity produced primarily through fossil fuels could ensure that the locations where the power is used pay a price that includes the health costs of its production.
