Wind farms have been blamed for disrupting the lives of birds, bats and, most recently, the land-bound sage grouse. Now the weatherman?
The massive spinning blades affixed to towers 200 feet high can appear on Doppler radar like a violent storm or even a tornado.
The phenomenon has affected several National Weather Service radar sites in different parts the country, even leading to a false tornado alert near Dodge City, Kansas, in the heart of Tornado Alley. In Des Moines, Iowa, the weather service received a frantic warning from an emergency worker who had access to Doppler radar images.
The alert was quickly called off in Kansas and meteorologists calmed the emergency worker down, but with enough wind turbines going up last year to power more than 6 million homes and a major push toward alternative energy, more false alerts seem inevitable.
New installations are concentrated, understandably in windy states like Texas, Oklahoma, Kansas, Colorado and Iowa, all part of Tornado Alley.
Texas, which has more tornadoes than any other state, also has the most wind power capacity.
Dave Zaff, science and operations officer with the National Weather Service office in Buffalo, N.Y., describes the wind farms 20 to 35 miles to the southeast as "more of a pimple or a blotch on your face" that 99 percent of the time will not pose a problem.
But what about those busy, high-stress periods when a meteorologist is tasked with making quick decisions as storms grow violent? In a worse-case scenario, a forecaster could disregard a real storm for turbine interference, but, more likely, would err on the side of caution, Zaff said.
"If you take a glance and then all of the sudden you see red, you might issue an incorrect warning as a result," he said.
Problems began to surface about three years ago, and seem to occur where a wind farm is built within about 11 miles of a Doppler site, said Tim Crum, with the weather service's radar operations center in Norman, Oklahoma.
That could become a bigger problem because the same terrain is attractive for both weather radar and wind farms.
"They want to be out in relatively exposed areas, high terrain, those sorts of things," Crum said. "So we sometimes are looking for the same ground, although we're already there.''
Software can easily filter out buildings, cell towers and mountain ridges on radar screens. Yet because weather radar seeks motion to warn of storms, there's no way to filter out the spinning blades.
Microwave radio signals are beamed toward a particular point and meteorologists listen for the "reflection." Experts can pick out the shape of a storm, or a tornado.
The splatter of green, yellow, orange and red on Doppler screens that are caused by wind farms can look very much like a tornado or a storm.
In Kansas, it was a computer program that picked up on the pattern and issued the alert. A meteorologist who was aware of the phenomenon quickly called off the alert.
The weather service is trying to improve its technology so that meteorologists during severe weather events can more easily tell the difference between dangerous storms and wind farms.
But there are now discussions about shutting down the wind farms when bad storms roll in.
The weather service has no say in where wind farms are sited, though it has analyzed some 500 proposed wind projects in an attempt to cut down on false alarms through better siting and layouts, said Crum.
It is also meeting regularly with AWEA, the wind power trade group.
Laurie Jodziewicz, AWEA's manager of siting policy, said the association is making sure its members understand the emerging issue and that they consider their projects' potential effects sooner rather than later.
"You can move turbines around as you're planning, but once they're in the ground they're really, really difficult to move,'' Jodziewicz said.
✅ Transmission and distribution fees rise 5-10 percent annually
Calgarians should expect to be charged more for their electricity bills amid significant demand on the grid and a transition to above-average rates across Alberta.
ENMAX, one of the most-used electricity providers in the city, has sent an email to customers notifying them of higher prices for the rest of the winter months.
“Although fluctuations in electricity market prices are normal, we have seen a general trend of increasing rates over time,” the email to customers read.
“The price volatility we are forecasting is due to market factors beyond a single energy provider, including but not limited to expectations for a colder-than-normal winter and changes in electricity supply and demand in Alberta’s wholesale market. ”
Earlier this month, the province set a record for electricity usage during a bitterly cold stretch of weather.
According to energy comparison website energyrates.ca, Alberta’s energy prices have increased by 34 per cent between November 2020 and 2021.
“One of the reasons that this increase seems so significant is we’re actually coming off of a low period in the market,” the site’s founder Joel MacDonald told Global News. “You’re seeing rates well below average transitioning to well above average.”
According to ENMAX’s rate in January, the price of electricity currently sits at 15.9 cents per kilowatt-hour, with an electricity price spike from 7.9 cents per kilowatt-hour last year.
MacDonald said prices for electricity have been relatively low since 2018 but a swing in the price of oil has created more activity in the province’s industrial sector, and in turn more demand on the power grid.
According to MacDonald, the price increase can also be attributed to the removal of a consumer price cap that limited regulated rates to 6.8 cents per kilowatt-hour for households and small businesses with lower demand, which, after the carbon tax was repealed, initially remained in place.
Although the cap was scrapped by the UCP three years ago, he said energy bills now depend on the rate set by the market.
“What’s increased now recently is actually the price per kilowatt, and the (transmission and distribution) charges have only increased, but annually they increase between five and 10 per cent,” MacDonald said. “So the portion of your bill that’s increasing is different than what Albertans are typically used to, or at least in recent memory.”
But Albertans do have options, MacDonald said.
As part of its email to customers, ENMAX sent a list of energy saving tips to reduce energy consumption in people’s homes, including using cold water for laundry and avoiding dryer use, energy-efficient lightbulbs and unplugging electronics when they are not in use.
Retailers also offer contracts with floating or fixed rates for consumers.
“Fixed rates, obviously, you’re going to pick your price. It’s going to be the same each and every single month,” MacDonald said. “Floating rate is based off the wholesale spot market, and that has been exceptionally high the last few months.”
He said consumers looking to save money when electricity prices are high should look into a fixed rate.
Toyota and Honda Moving e delivers hydrogen backup power via a fuel cell bus, portable batteries, and power exporters for disaster relief, emergency electricity, and grid outage support near charging stations and microgrids.
Key Points
A hydrogen mobile power system using a fuel cell bus and batteries to supply emergency electricity during disasters.
✅ Fuel cell bus outputs up to 18 kW, 454 kWh capacity
✅ Portable batteries and power exporter deliver site power
✅ Supports disaster relief near hydrogen charging stations
Without the uninterrupted supply of power and electricity, modern economies would be unable to function. A blackout can impact everything from transport to health care, communication, and even water supplies, as seen in a near-blackout in Japan that strained the grid. It is one of the key security concerns for every government on earth, a point underscored by Fatih Birol on electricity options during the pandemic, and the growth in the market for backup power reflects that fact. In 2018, the global Backup Power market was $14.9 billion and is expected to reach $22 billion by the end of 2025, growing at a CAGR of 5.0 percent between 2019 and 2025.
It is against this backdrop that Toyota and Honda have come up with a new and innovative solution to providing electricity during disasters. The two transport giants have launched a mobile power generation system that consists of a fuel cell bus that can carry a large amount of hydrogen, aligned with Japan's hydrogen energy system efforts underway, portable external power output devices, and portable batteries to disaster zones. The system, which is called ‘Moving e’ includes Toyota’s charging station fuel cell bus, Honda’s power exporter 9000 portable external power output device, two types of Honda’s portable batteries, and a Honda Mobile Power Pack Charge & Supply Concept charger/discharger for MPP.
In simple terms, the bus would drive to a disaster zone, and while other approaches such as gravity energy storage are advancing, the portable batteries and power output devices would be used to extract electricity from the fuel cell bus and provide it wherever it is needed. The bus itself can generate 454kWh and has a maximum output of 18kW. That is more than enough energy to supply electricity for large indoor areas such as an evacuation area. The bus is also fitted with space for people to nap or rest during a disaster.
The two companies plan to test the effectiveness of the Moving e at multiple municipalities and businesses. These locations will have to be within 100km of a hydrogen station that is capable of refueling the bus. If the bus has to drive 200km, then its electricity supply to the disaster zone would drop from 490kwh to 240kWh. While there aren’t currently enough hydrogen stations to make this a realistic scenario for all disaster zones, especially as countries push for hydrogen-ready power plants in Germany and related infrastructure, hydrogen is growing increasingly competitive with gasoline and diesel.
While gas generators are still considered more reliable and generally cheaper than backup batteries for home use, cleaner backup power is growing increasingly popular, and novel storage like power-to-gas in Europe is also advancing across grids. This latest development by Toyota and Honda is another step forward for the battery and fuel cell industry, with initiatives like PEM hydrogen R&D in China accelerating progress, – especially considering the meteoric rise of hydrogen energy in recent years.
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.
Saskatchewan COVID-19 economic impact: real-time data shows drops in electricity demand, oil well licensing, traffic and tickets, plus spikes in internet usage, government site visits, remote work, and alcohol wholesale volumes.
Key Points
COVID-19 reduced energy use, drilling and traffic, while pushing activity online; jobs, rents and sales show strain.
✅ Electricity demand down 6.7%; residential usage up
✅ Oil well license applications fell 15-fold in April
✅ Internet traffic up 16%-46%; wireless LTE up 34%
We’re only just beginning to grasp how COVID-19 has upended Saskatchewan’s economy, its government and all of our lives.
The numbers that usually make headlines — job losses, economic contraction, bankruptcies — are still well behind the pace of the virus and its toll.
But other numbers change more quickly. Saskatchewan people are using less power, and the power industry is adopting on-site staffing plans to ensure reliability as conditions evolve. We’re racking up fewer speeding tickets. And as new restrictions come, we’re clicking onto Saskatchewan.ca as much as 10,000 times per minute.
Here’s some data that provides a first glimpse into how much our province has changed in just six weeks.
Electricity use tends to rise and fall in tandem with the health of the economy, and the most recent data from SaskPower suggests businesses are powering down, while regional utilities such as Manitoba Hydro seek unpaid days off to trim costs.
Peak load requirements between March 15 and April 26 were 220 MW lower than during the same period in 2019, and elsewhere BC Hydro is posting COVID-19 updates at Site C as it manages project impacts. That’s a decrease of 6.7 per cent, with total load on April 29 at 2,551 MW. A megawatt is enough electricity to power about 1,000 homes.
But it’s not homes that are turning off the lights. SaskPower spokesman Joel Cherry said commercial and industrial usage is down, while residential demand is up, with household electricity bills rising as more people stay home.
The timing of power demand has also shifted, a pattern seen as residential electricity use rises during work-from-home routines. Peak load would usually come around 8 or 9 p.m. in April. Now it’s coming earlier, typically between 5 and 6 p.m.
Oil well applications fall 15-fold Oil prices have cratered since late February, and producers in Saskatchewan have reacted by pulling back on drilling plans, while neighbouring Alberta provides transition support for coal workers amid broader energy shifts.
Applications for well licences fell from 242 in January to 203 in February (including nine potash and one helium operations), before dropping to 84 in March. April, the month benchmark oil prices went negative for one day, producers submitted just 15 applications.
That’s 15 times fewer than the 231 applications the Ministry of Energy and Resources received in April 2019.
Well licences are needed for drilling, operating, injecting, producing or exploring an oil and gas or potash well in the province.
There has been no clear trend in well abandonment, however. There were 176 applications for abandonment in March and 155 in April, roughly in line with figures from the year before.
SGI spokesman Tyler McMurchy believes the lower numbers might stem from a combination of lower traffic volumes during part of the month, possibly combined with a shift in police priorities. The March 2020 numbers are also well below January and February figures.
Indeed, the Ministry of Highways and infrastructure reported a 16 per cent decrease in average daily traffic last month compared to March 2019, through its traffic counts at 11 different spots on highways across the province.
In Regina, traffic counts at 16 locations dropped from a high of 2.1 million in the first week of March to a low of 1.3 million during the week of March 22. That’s a 44 per cent decrease.
Counts have gradually recovered to 1.6 million in the weeks since. The data was fairly consistent at all 16 spots, which are largely major intersections, though the city cautioned they may not be representative of Regina as a whole.
Tickets for cellphone use while driving also fell, dropping from 562 in February to 314 in March. McMurchy noted that distracted driving numbers in general have been falling since November as stiffer penalties were announced. Impaired driving tickets were up, by contrast, but still within a typical range.
Internet traffic shoots up 16 per cent, far more for rural high speed You may be spending a lot more time on Netflix and Facebook in the age of social distancing, and SaskTel has noticed.
From late February to late April, SaskTel has seen “very significant increases in provincial data traffic.” DSL and fibre optic networks have handled a 16 per cent increase in traffic, while demand on the wireless LTE network is up 34 per cent.
Usage on the Fusion network up 46 per cent. That network serves rural areas that don’t have access to other high-speed options.
The specific reference dates for comparison were February 24 and April 27.
“We attribute these changes in data usage to the pandemic and not expected seasonal or yearly shifts in usage patterns,” said spokesman Greg Jacobs.
Saskatchewan.ca was attracting just 70 page views per minute on average in February. But page views jumped over 10,000 per minute at 2:38 p.m. on March 18, as Moe was still announcing the new measures.
That’s a 14,000 per cent increase.
For all of March, visitor sessions on the site clocked in at 3,905,061, almost four times the 944,904 recorded for February.
Bureaucracy has increasingly migrated to cyberspace, with 62 per cent of civil servants now working from home. Government Skype calls, both audio and video, have tripled from 12,000 sessions per day to 35,000.Telephone conference calls increased by a factor of 14 from the first week of February to the second full week of April, with 25 times more weekly call participants.
The Ministry of Central Services reported a 17 per cent jump in emails received by government over the past two months, excluding the Ministry of Health.
But as civil servants spend more time on their computers, the government’s fleet is spending a lot less time on the road. The ministry has purchased 40 per cent fewer litres of fuel for its vehicles over the past four weeks, compared to the same time last year.
Alcohol wholesale volumes up 22 per cent, then fall back to normal Retailers bought more alcohol from the Saskatchewan Liquor and Gaming Authority (SLGA) last month, just as the government began tightening pandemic restrictions.
Wholesale sales volumes were up 22 per cent over March 15 to 28, compared to the same period in 2019. SLGA spokesman David Morris said the additional demand “was likely the result of retailers stocking-up as restrictions related to COVID-19 took effect.”
But the jump didn’t last. Wholesale volumes were back to normal for the first two weeks of April. SLGA did notice a very slight uptick last week, however, with volumes out of its distribution centre up three per cent. The numbers do not include Brewer’s Distributors Ltd.
It’s unclear how much more alcohol consumers actually purchased, since province-wide retail numbers were not available.
There was no discernible trend in March for anti-anxiety medication, however. The number of prescriptions filled for benzodiazepines like Valium, Xanax and Ativan see-sawed over March, according to data provided by the College of Physicians and Surgeons, but its associate registrar does not believe the trends are statistically relevant.
One-fifth of tenants miss April rent About 20 per cent of residential rent went totally unpaid in the first six days of April, according to the Saskatchewan Landlord Association (SLA).
The precise number is 19.7 per cent, but there’s some uncertainty due to the survey method, which is based on responses from 300 residential landlords with 14,000 units. An additional 12 per cent of tenants paid a portion of their rent, but not the full amount. The figures do not include social housing.
Cameron Choquette, the association’s executive officer, partly blames the province’s decision to suspend most landlord tenant board hearings for evictions, saying it “allows more people to take advantage of landlords by not paying their rent and not facing any consequences.”
The government has defended the suspension by saying it’s needed to ensure everyone has a safe place to self-isolate if needed during the pandemic.
March’s jobs numbers were bad, with almost 21,000 fewer Saskatchewan people employed compared to February.
April’s labour force survey is expected on Friday. But new April numbers released Wednesday show that two-thirds of the province’s businesses managed to avoid laying off staff almost entirely.
According to Statistics Canada, 66.2 per cent of businesses reported laying off between zero and one per cent of their employees due to COVID-19. That was better than any other province. Just 7.6 per cent laid off all of their employees, again the best number outside the territories. The survey period was April 3 to 24.
Some businesses are even hiring. Walmart, for instance, has hired 300 people in Saskatchewan since mid-March.
Trade and Export Development Minister Jeremy Harrison chalked the data up to a relatively more optimistic business outlook in Saskatchewan, combined with “very targeted” restrictions and a support program for small and medium businesses.
That support program, which provides $5,000 grants to qualifying businesses affected by government restrictions, has only been around for three weeks. But it’s already been bombarded with 6,317 applications.
The total value of those applications would be $24,178,000, according to Harrison. Of them, 3,586 have been approved with a value of $11,755,000.
Businesses are coming to Harrison’s ministry with thousands of questions. Since it opened in March, the Business Response Team has received 4,125 calls and 1,758 emails.
The kinds of questions have changed over the course of the pandemic. Many are now asking when they can open their doors, according to Harrison, as they wonder about “grey areas” in the Re-Open Saskatchewan plan.
CO2 Tax for UK Offshore Energy Efficiency can accelerate adoption of aero-derivative gas turbines, flare gas recovery, and combined cycle power, reducing emissions on platforms like Equinor's Mariner and supporting net zero goals.
Key Points
A carbon price pushing operators to adopt efficient turbines, flare recovery, and combined cycle to cut emissions.
✅ Aero-derivative turbines beat industrial units on efficiency
✅ Flare gas recovery cuts routine flaring and fuel waste
✅ Combined cycle raises efficiency and lowers emissions
By Tom Baxter
The recent Energy Voice article from the Equinor chairman concerning the Mariner project heralding a ‘significant point of reference’ for growth highlighted the energy efficiency achievements associated with the platform.
I view energy efficiency as a key enabler to net zero, and alongside this the UK must start large-scale storage to meet system needs; it is a topic I have been involved with for many years.
As part of my energy efficiency work, I investigated Norwegian practices and compared them with the UK.
There were many differences, here are three;
1. Power for offshore installations is usually supplied from gas turbines burning fuel from the oil and gas processing plant, and even as the UK's offshore wind supply accelerates, installations convert that to electricity or couple the gas turbine to a machine such as a gas compressor.
There are two main generic types of gas turbine – aero-derivative and industrial. As the name implies aero-derivatives are aviation engines used in a static environment. Aero-derivative turbines are designed to be energy efficient as that is very import for the aviation industry.
Not so with industrial type gas turbines; they are typically 5-10% less efficient than a comparable aero-derivative.
Industrial machines do have some advantages – they can be cheaper, require less frequent maintenance, they have a wide fuel composition tolerance and they can be procured within a shorter time frame.
My comparison showed that aero-derivative machines prevailed in Norway because of the energy efficiency advantages – not the case in the UK where there are many more offshore industrial gas turbines.

2. Offshore gas flaring is probably the most obvious source of inefficient use of energy with consequent greenhouse gas emissions.
On UK installations gas is always flared due to the design of the oil and gas processing plant.
Though not a large quantity of gas, a continuous flow of gas is routinely sent to flare from some of the process plant.
In addition the flare requires pilot flames to be maintained burning at all times and, while Europe explores electricity storage in gas pipes, a purge of hydrocarbon gas is introduced into the pipes to prevent unsafe air ingress that could lead to an explosive mixture.
On many Norwegian installations the flare system is designed differently. Flare gas recovery systems are deployed which results in no flaring during continuous operations.
Flare gas recovery systems improve energy efficiency but they are costly and add additional operational complexity.
3. Returning to gas turbines, all UK offshore gas turbines are open cycle – gas is burned to produce energy and the very hot exhaust gases are vented to the atmosphere. Around 60 -70% of the energy is lost in the exhaust gases.
Some UK fields use this hot gas as a heat source for some of the oil and gas treatment operations hence improving energy efficiency.
There is another option for gas turbines that will significantly improve energy efficiency – combined cycle, and in parallel plans for nuclear power under the green industrial revolution aim to decarbonise supply.
Here the exhaust gases from an open cycle machine are taken to a separate turbine. This additional turbine utilises exhaust heat to produce steam with the steam used to drive a second turbine to generate supplementary electricity. It is the system used in most UK power stations, even as UK low-carbon generation stalled in 2019 across the grid.
Open cycle gas turbines are around 30 – 40% efficient whereas combined cycle turbines are typically 50 – 60%. Clearly deploying a combined cycle will result in a huge greenhouse gas saving.
I have worked on the development of many UK oil and gas fields and combined cycle has rarely been considered.
The reason being is that, despite the clear energy saving, they are too costly and complex to justify deploying offshore.
However that is not the case in Norway where combined cycle is used on Oseberg, Snorre and Eldfisk.
What makes the improved Norwegian energy efficiency practices different from the UK – the answer is clear; the Norwegian CO2 tax.
A tax that makes CO2 a significant part of offshore operating costs.
The consequence being that deploying energy efficient technology is much easier to justify in Norway when compared to the UK.
Do we need a CO2 tax in the UK to meet net zero – I am convinced we do. I am in good company. BP, Shell, ExxonMobil and Total are supporting a carbon tax.
Not without justification there has been much criticism of Labour’s recent oil tax plans, alongside proposals for state-owned electricity generation that aim to reshape the power market.
To my mind Labour’s laudable aims to tackle the Climate Emergency would be much better served by supporting a CO2 tax that complements the UK's coal-free energy record by strengthening renewable investment.
Texas PUC Spanish Power to Choose mandates bilingual parity in deregulated electricity markets, ensuring equal access to plans, transparent pricing, consumer protection, and provider listings for Spanish speakers, mirroring the English site offerings statewide.
Key Points
PUC mandate requiring identical Spanish and English plan listings for fair access in the deregulated power market.
✅ Orders parity across English and Spanish plan listings
✅ Increases transparency in a deregulated electricity market
✅ Deadline set for providers to post on both sites
The state’s Public Utility Commission has ordered that the Spanish-language version of the Power to Choose website provide the same options available on the English version of the site, a move that comes as shopping for electricity is getting cheaper statewide.
Texas is one of a handful of states with a deregulated electricity market, with ongoing market reforms under consideration to avoid blackouts. The idea is to give consumers the option to pick power plans that they think best fit their needs. Customers can find available plans on the state’s Power To Choose website, or its Spanish-language counterpart, Poder de Escoger. In theory, those two sites should have the exact same offerings, so no one is disadvantaged. But the Texas Public Utility Commission found that wasn’t the case.
Houston Chronicle business reporter Lynn Sixel has been covering this story. She says the Power to Choose website is important for consumers facing the difficult task of choosing an electric provider in a deregulated state, where electricity complaints have recently reached a three-year high for Texans.
“There are about 57 providers listed on the [English] Power to Choose website, and news about retailers like Griddy underscores how varied the offerings can be across providers. [Last week] there were only 23 plans on the Spanish Power to Choose site,” Sixel says. “If you speak Spanish and you’re looking for a low-cost plan, as of last week, it would have been difficult to find some of the really great offers.”
Mustafa Tameez, managing director of Outreach Strategists, a Houston firm that consults with companies and nonprofits on diversity, described this issue as a type of redlining.
“He’s referring to a practice that banks would use to circle areas on maps in which the bank decided they did not want to lend money or would charge higher rates,” Sixel says. “Typically it was poor minority neighborhoods. Those folks would not get the same great deals that their Anglo neighbors would get.”
DeAnn Walker, chairman of the Public Utility Commission, said she was not at all happy about the plans listings in a meeting Friday, against a backdrop where Texas utilities have recently backed out of a plan to create smart home electricity networks.
“She gave a deadline of 8 a.m. Monday morning for any providers who wanted to put their plans on the Power to Choose website, must put them on both the Spanish language and the English language versions,” Sixel says. “All the folks that I talked to really had no idea that there were different plans on both sites and I think that there was sort of an assumption.”
