SaskPower Encourages response for green power

Cloud Data Centers Environmental Impact highlights massive electricity use, carbon emissions, and cooling demands, with coal-heavy grids in China; big tech shifts to renewable energy, green data centers, and cooler climates to boost sustainability.

Key Points

Energy use, emissions, and cooling load of cloud systems, and shifts to renewables to reduce climate impact.

✅ Global data centers use 3-5% of electricity, akin to airlines

✅ Cooling drives energy demand; siting in cool climates saves power

✅ Shift from coal to renewables lowers CO2 and improves PUE

A hidden environmental price makes storing data in the cloud a costly convenience.

Between 3 to 5% of all electricity used globally comes from data centers that house massive computer systems, with computing power forecasts warning consumption could climb, an amount comparable to the airline industry, says Ben Brock Johnson, Here & Now’s tech analyst.

Instead of stashing information locally on our own personal devices, the cloud allows users to free up storage space by sending photos and files to data centers via the internet.

The cloud can also use large data sets to solve problems and host innovative technologies that make cities and homes smarter, but storing information at data centers uses energy — a lot of it.

"Ironically, the phrase 'moving everything to the cloud' is a problem for our actual climate right now," Johnson says.

A new study from Greenpeace and North China Electric Power University reports that in five years, China's data centers alone will consume as much power as the total amount used in Australia in 2018. The industry's electricity consumption is set to increase by 66% over that time.

Buildings storing data produced 99 million metric tons of carbon last year in China, the study finds, with SF6 in electrical equipment compounding warming impacts, which is equivalent to 21 million cars.

The amount of electricity required to run a data center is a global problem, but in China, 73% of these data centers run on coal, even as coal-fired electricity is projected to fall globally this year.

The Chinese government started a pilot program for green data centers in 2015, which Johnson says signals the country is thinking about the environmental consequences of the cloud.

"Beijing’s environmental awareness in the last decade has really come from a visible impact of its reliance on fossil fuels," he says. "The smog of Chinese cities is now legendary and super dangerous."

The country's solar power innovations have allowed the country to surpass the U.S. in cleantech, he says.

Chinese conglomerate Alibaba Group has launched data centers powered by solar and hydroelectric power.

"While I don't know how committed the government is necessarily to making data centers run on clean technology," Johnson says. "I do think it is possible that a larger evolution of the government's feelings on environmental responsibility might impact this newer tech sector."

In the U.S., there has been a big push to make data centers more sustainable amid warnings that the electric grid is not designed for mounting climate impacts.

Canada has made notable progress decarbonizing power, with nationwide electricity gains supporting cleaner data workloads.

Apple now says all of its data centers use clean energy. Microsoft is aiming for 70% renewable energy by 2023, aligning with declining power-sector emissions as producers move away from coal.

Amazon is behind the curve, for once, with about 50%, Johnson says. Around 1,000 employees are planning to walk out on Sept. 20 in protest of the company’s failure to address environmental issues.

"Environmental responsibility fits the brand identities these companies want to project," he says. "And as large tech companies become more competitive with each other, as Apple becomes more of a service company and Google becomes a device company, they want to convince users more and more to think of them as somehow different even if they aren't."

Google and Facebook are talking about building data centers in cooler places like Finland and Sweden instead of hot deserts like Nevada, he says.

In Canada, cleaning up electricity is critical to meeting climate pledges, according to recent analysis.

Computer systems heat up and need to be cooled down by air conditioning units, so putting a data center in a warm climate will require greater cooling efforts and use more energy.

In China, 40% of the electricity used at data centers goes toward cooling equipment, according to the study.

The more data centers consolidate, Johnson says they can rely on fewer servers and focus on larger cooling efforts.

But storing data in the cloud isn't the only way tech users are unknowingly using large amounts of energy: One Google search requires an amount of electricity equivalent to powering a 60-watt light bulb for 17 seconds, magazine Yale Environment 360 reports.

"In some ways, we're making strides even as we are creating a bigger problem," he says. "Which is like, humanity's MO, I guess."

Utility Pandemic Preparedness strengthens grid resilience through continuity planning, critical infrastructure protection, DOE-DHS coordination, onsite sequestration, skeleton crews, and deferred maintenance to ensure reliable electric and gas service for commercial and industrial customers.

Key Points

Plans that sustain grid operations during outbreaks using staffing limits, access controls, and deferred maintenance.

✅ Deferred maintenance and restricted site access

✅ Onsite sequestering and skeleton crew operations

✅ DOE-DHS coordination and control center staffing

Commercial and industrial businesses can rest assured that the current pandemic poses no real threat to our utilities, with the U.S. grid remaining reliable for now, as disaster planning has been key to electric and gas utilities in recent years, writes Forbes. Beginning a decade ago, the utility and energy industries evolved detailed pandemic plans, outlining what to know about the U.S. grid during outbreaks, which include putting off maintenance and routine activities until the worst of the pandemic has passed, restricting site access to essential personnel, and being able to run on a skeleton crew as more and more people become ill, a capability underscored by FPL's massive Irma response when crews faced prolonged outages.

One possible outcome of the current situation is that the US electric industry may require essential staff to live onsite at power plants and control centers, similar to Ontario work-site lockdown plans under consideration, if the outbreak worsens; bedding, food and other supplies are being stockpiled, reflecting local response preparations many utilities practice, Reuters reported. The Great River Energy cooperative, for example, has had a plan to sequester essential staff in place since the H1N1 bird flu crisis in 2009. The cooperative, which runs 10 power plants in Minnesota, says its disaster planning ensured it has enough cots, blankets and other necessities on site to keep staff healthy.

Electricity providers are now taking part in twice-weekly phone calls with officials at the DOE, the Department of Homeland Security, and other agencies, as Ontario demand shifts are monitored, according to the Los Angeles Times. By planning for a variety of worst case scenarios, including weeks-long restorations after major storms, “I have confidence that the sector will be prepared to respond no matter how this evolves,” says Scott Aaronson, VP of security and preparedness for the Edison Electric Institute.

Freedom Cannabis solar array powers an Acheson cannabis facility with 4,574 rooftop panels, a 1,830-kilowatt system by Enmax, cutting greenhouse gas emissions, lowering energy costs, and advancing renewable energy, sustainability, and operational efficiency in Edmonton.

Key Points

A 1,830-kW rooftop solar system with 4,574 panels, cutting GHG emissions and energy costs at the Acheson facility.

✅ 1,830-kW array offsets 1,000+ tonnes GHG annually

✅ Supplies ~8% of annual power; saves $200k-$300k per year

✅ 4,574 rooftop panels installed by Enmax in Acheson

Electricity consumption is one of the biggest barriers to going green in the cannabis industry, where the energy demands of cannabis cultivation often complicate sustainability, but an Edmonton-area pot producer has come up with a sunny solution.

Freedom Cannabis unveiled the largest rooftop solar system used by a cannabis facility in Canada at its 126,000-square foot Acheson location, 20 kilometres west of Edmonton, as solar power in Alberta continues to surge, on Tuesday.

The "state-of-the-art" 1,830-kilowatt solar array—made up of 4,574 panels—was supplied by Enmax and will offset more than 1,000 tonnes of greenhouse gas emissions each year, reflecting how new Alberta solar facilities are undercutting natural gas on price, the company said.

That will supply roughly eight per cent of the building's annual power consumption and reduce costs by $200,000 to $300,000 annually.

"This strategy will supplement our operating costs for power by up to eight to 10 per cent, so it is something that in time will save us costs on power requirements," said Troy Dezwart, co-founder of Freedom Cannabis.

Dezwart said sustainability was an important issue to the company from its outset, aligning with an Alberta renewable energy surge that is expected to power thousands of jobs.

"We're fortunate enough to be able to have these types of options and pursue them," said Dezwart.

The entire system cost Freedom Cannabis $2.6 million to build, but nearly a million of that came from a provincial rebate program that has since been cancelled by the UCP government, even as a federal green electricity deal with an Edmonton company signals ongoing support.

The company cited a 2017 report that found cannabis growers in the U.S. used enough electricity to power 1.7-million homes, and said cannabis-related power consumption is expected to increase by 1,250 per cent in Ontario over the next five years, even though Canadian solar demand has been lagging overall.

“It’s more important than ever for businesses to manage their energy footprint, and solar is an important part of that solution,” Enmax director Jason Atkinson, said. “This solar installation will help reduce operating costs and offset a significant portion of GHG emissions for decades to come.”

Freedom says it has other initiatives underway to reduce its footprint, in a region planning the Edmonton airport solar farm among other projects, including water remediation and offering 100 per cent recyclable cannabis packaging tins.

The company's first crops are expected to go to market in December.

California Electricity Reserve Mandate requires 3.3 GW of new capacity to bolster grid reliability amid solar power volatility, peak demand, and wildfire-driven blackouts, as CPUC directs PG&E, Edison, and Sempra to procure resource adequacy.

Key Points

A CPUC order for utilities to add 3.3 GW of reserves, safeguarding grid reliability during variable renewables and peaks

✅ 3.3 GW procurement to meet resource adequacy targets

✅ Focus on grid reliability during peak evening demand

✅ Prioritizes renewables, storage; limits new fossil builds

As if California doesn’t have enough problems with its electric service, now state regulators warn the state may be short on power supplies by 2021 if utilities don’t start lining up new resources now.

In the hopes of heading off a shortfall as America goes electric, the California Public Utilities Commission has ordered the state’s electricity providers to secure 3.3 additional gigawatts of reserve supplies. That’s enough to power roughly 2.5 million homes. Half of it must be in place by 2021 and the rest by August 2023.

The move comes as California is already struggling to accommodate increasingly large amounts of solar power that regularly send electricity prices plunging below zero and force other generators offline so the region’s grid doesn’t overload. The state is also still reeling from a series of deliberate mass blackouts that utilities imposed last month to keep their power lines from sparking wildfires amid strong winds. And its largest power company, PG&E Corp., went bankrupt in January.

Now as natural gas-fired power plants retire under the state’s climate policies, officials are warning the state could run short on electricity on hot evenings, when solar production fades and commuters get home and crank up their air conditioners. “We have fewer resources that can be quickly turned on that can meet those peaks,” utilities commission member Liane Randolph said Thursday before the panel approved the order to beef up reserves.

The 3.3 gigawatts that utilities must line up is in addition to a state rule requiring them to sign contracts for 15% more electricity than they expect to need. Some critics question the need for added supplies, particularly after the state went on a plant-building boom in the 2000s.

But California’s grid managers say the risk of a shortfall is real and could be as high as 4.7 gigawatts, especially during heat waves that test the grid again. Mark Rothleder, with the California Independent System Operator, said the 15% cushion is a holdover from the days before big solar and wind farms made the grid more volatile. Now it may need to be increased, he said.

“We’re not in that world anymore,” said Rothleder, the operator’s vice president of state regulatory affairs. “The complexity of the system and the resources we have now are much different.”

The state’s three major utilities, PG&E, Edison International and Sempra Energy, will be largely responsible for securing new supplies. The commission banned fossil fuels from being used at any new power generators built to meet the requirement — though it left the door open for expansions at existing ones.

Some analysts argue California is exporting its energy policies to Western states, making electricity more costly and less reliable.

PG&E said in an emailed statement that it was pleased the commission didn’t adopt an earlier proposal to require 4 gigawatts of additional resources. Edison similarly said it was “supportive.” Sempra didn’t immediately respond with comment.

Extending Deadlines

The pending plant closures are being hastened by a 2020 deadline requiring California’s coastal generators to stop using aging seawater-cooling systems. Some gas-fired power plants have said they’ll simply close instead of installing costly new cooling systems. So the commission on Thursday also asked California water regulators to extend the deadline for five plants.

The Sierra Club, meanwhile, called on regulators to turn away from fossil fuels altogether, saying their decision Thursday “sets California back on its progress toward a clean energy future.”

The move to push back the deadline also faces opposition from neighboring towns. Redondo Beach Mayor Bill Brand, whose city is home to one of the plants in line for an extension, told the commission it wasn’t necessary, since California utilities already have plenty of electricity reserves.

“It’s just piling on to that reserve margin,” Brand said.

U.S. Residential Electricity Bills rose on stronger demand, inflation, and fuel costs, with higher retail prices, kWh consumption, and extreme weather driving 2022 spikes; forecasts point to stable summer usage and slight price increases.

Key Points

They are average household power costs shaped by prices, kWh use, weather, and upstream fuel costs.

✅ 2022 bills up 13% nominal, 5% real vs. 2021

✅ Retail price rose 11%; consumption up 2% to 907 kWh

✅ Fuel costs to plants up 34%, pressuring rates

In nominal terms, the average monthly electricity bill for residential customers in the United States increased 13% from 2021 to 2022, rising from $121 a month to $137 a month. After adjusting for inflation—which reached 8% in 2022, a 40-year high—electricity bills increased 5%. Last year had the largest annual increase in average residential electricity spending since we began calculating it in 1984. The increase was driven by a combination of more extreme temperatures, which increased U.S. consumption of electricity for both heating and cooling, and higher fuel costs for power plants, which drove up retail electricity prices nationwide.

Residential electricity customers’ monthly electricity bills are based on the amount of electricity consumed and the retail electricity price. Average U.S. monthly electricity consumption per residential customer increased from 886 kilowatthours (kWh) in 2021 to 907 kWh in 2022, even as U.S. electricity sales have declined over the past seven years. Both a colder winter and a hotter summer contributed to the 2% increase in average monthly electricity consumption per residential customer in 2022 because customers used more space heating during the winter and more air conditioning during the summer, with some states, such as Pennsylvania, facing sharp winter rate increases.

Although we don’t directly collect retail electricity prices, we do collect revenues from electricity providers that allow us to determine prices by dividing by consumption, and industry reports show major utilities spending more on electricity delivery than on power production. In 2022, the average U.S. residential retail electricity price was 15.12 cents/kWh, an 11% increase from 13.66 cents/kWh in 2021. After adjusting for inflation, U.S. residential electricity prices went up by 2.5%.

Higher fuel costs for power plants drove the increase in residential retail electricity prices. The cost of fossil fuels—including natural gas prices, coal, and petroleum—delivered to U.S. power plants increased 34%, from $3.82 per million British thermal units (MMBtu) in 2021 to $5.13/MMBtu in 2022. The higher fuel costs were passed along to residential customers and contributed to higher retail electricity prices, and Germany power prices nearly doubled over a year in a related trend.

In the first three months of 2023, the average U.S. residential monthly electricity bill was $133, or 5% higher than for the same time last year, according to data from our Electric Power Monthly. The increase was driven by a 13% increase in the average U.S. residential retail electricity price, which was partly offset by a 7% decrease in average monthly electricity consumption per residential customer, and industry outlooks also see U.S. power demand sliding 1% on milder weather. This summer, we expect that typical household electricity bills will be similar to last year’s, with customers paying about 2% more on average. The slight increase in electricity costs forecast for this summer stems from higher retail electricity prices but similar consumption levels as last summer.

Canada Power Grid Climate Resilience integrates extreme weather planning, microgrids, battery storage, renewable energy, vegetation management, and undergrounding to reduce outages, harden infrastructure, modernize utilities, and safeguard reliability during storms, ice events, and wildfires.

Key Points

Canada's grid resilience hardens utilities against extreme weather using microgrids, storage, renewables, and upgrades.

✅ Grid hardening: microgrids, storage, renewable integration

✅ Vegetation management reduces storm-related line contact

✅ Selective undergrounding where risk and cost justify

The increasing intensity of storms that lead to massive power outages highlights the need for Canada’s electrical utilities to be more robust and innovative, climate change scientists say.

“We need to plan to be more resilient in the face of the increasing chances of these events occurring,” University of New Brunswick climate change scientist Louise Comeau said in a recent interview.

The East Coast was walloped this week by the third storm in as many days, with high winds toppling trees and even part of a Halifax church steeple, underscoring the value of storm-season electrical safety tips for residents.

Significant weather events have consistently increased over the last five years, according to the Canadian Electricity Association (CEA), which has tracked such events since 2003.

Nearly a quarter of total outage hours nationally in 2016 – 22 per cent – were caused by two ice storms, a lightning storm, and the Fort McMurray fires, which the CEA said may or may not be classified as a climate event.

“It (climate change) is putting quite a lot of pressure on electricity companies coast to coast to coast to improve their processes and look for ways to strengthen their systems in the face of this evolving threat,” said Devin McCarthy, vice president of public affairs and U.S. policy for the CEA, which represents 40 utilities serving 14 million customers.

The 2016 figures – the most recent available – indicate the average Canadian customer experienced 3.1 outages and 5.66 hours of outage time.

McCarthy said electricity companies can’t just build their systems to withstand the worst storm they’d dealt with over the previous 30 years. They must prepare for worse, and address risks highlighted by Site C dam stability concerns as part of long-term planning.

“There needs to be a more forward looking approach, climate science led, that looks at what do we expect our system to be up against in the next 20, 30 or 50 years,” he said.

Toronto Hydro is either looking at or installing equipment with extreme weather in mind, Elias Lyberogiannis, the utility’s general manager of engineering, said in an email.

That includes stainless steel transformers that are more resistant to corrosion, and breakaway links for overhead service connections, which allow service wires to safely disconnect from poles and prevents damage to service masts.

Comeau said smaller grids, tied to electrical systems operated by larger utilities, often utilize renewable energy sources such as solar and wind as well as battery storage technology to power collections of buildings, homes, schools and hospitals.

“Capacity to do that means we are less vulnerable when the central systems break down,” Comeau said.

Nova Scotia Power recently announced an “intelligent feeder” pilot project, which involves the installation of Tesla Powerwall storage batteries in 10 homes in Elmsdale, N.S., and a large grid-sized battery at the local substation. The batteries are connected to an electrical line powered in part by nearby wind turbines.

The idea is to test the capability of providing customers with back-up power, while collecting data that will be useful for planning future energy needs.

Tony O’Hara, NB Power’s vice-president of engineering, said the utility, which recently sounded an alarm on copper theft, was in the late planning stages of a micro-grid for the western part of the province, and is also studying the use of large battery storage banks.

“Those things are coming, that will be an evolution over time for sure,” said O’Hara.

Some solutions may be simpler. Smaller utilities, like Nova Scotia Power, are focusing on strengthening overhead systems, mainly through vegetation management, while in Ontario, Hydro One and Alectra are making major investments to strengthen infrastructure in the Hamilton area.

“The number one cause of outages during storms, particularly those with high winds and heavy snow, is trees making contact with power lines,” said N.S. Power’s Tiffany Chase.

The company has an annual budget of $20 million for tree trimming and removal.

“But the reality is with overhead infrastructure, trees are going to cause damage no matter how robust the infrastructure is,” said Matt Drover, the utility’s director for regional operations.

“We are looking at things like battery storage and a variety of other reliability programs to help with that.”

NB Power also has an increased emphasis on tree trimming and removal, and now spends $14 million a year on it, up from $6 million prior to 2014.

O’Hara said the vegetation program has helped drive the average duration of power outages down since 2014 from about three hours to two hours and 45 minutes.

Some power cables are buried in both Nova Scotia and New Brunswick, mostly in urban areas. But both utilities maintain it’s too expensive to bury entire systems – estimated at $1 million per kilometre by Nova Scotia Power.

The issue of burying more lines was top of mind in Toronto following a 2013 ice storm, but that’s city’s utility also rejected the idea of a large-scale underground system as too expensive – estimating the cost at around $15 billion, while Ontario customers have seen Hydro One delivery rates rise in recent adjustments.

“Having said that, it is prudent to do so for some installations depending on site specific conditions and the risks that exist,” Lyberogiannis said.

Comeau said lowering risks will both save money and disruption to people’s lives.

“We can’t just do what we used to do,” said Xuebin Zhang, a senior climate change scientist at Environment and Climate Change Canada.

“We have to build in management risk … this has to be a new norm.”
