Bennie Phillips' employer makes money every time TVA is struggling to keep air conditioners humming during the hottest days of summer.

The grocery distribution company near Nashville gets paid essentially to unplug its 53,000-square-foot freezer for a couple of hours on short notice during peak hours for power demand.

"They actually give us a payment for how much (electricity) we curtail," said Phillips, facilities manager for the 350-employee Associated Wholesale Grocers Inc.

Similar programs are being tested by utilities nationwide as they try to reduce energy use and the costs of buying extra emergency power from other providers.

TVA, the nation's largest public utility, began testing its "demand response" conservation program last summer with smaller companies. AWG was one of about 20 businesses that participated, totaling about 4 megawatts of short-term reserve capacity.

Pleased with the performance, TVA has expanded the program this year to customers of distributors in Nashville, Memphis, Knoxville and Huntsville, Ala. The initial goal is 50 megawatts of energy reserve, growing to 110 to 125 megawatts in three years - about the output of one combustion unit at a small peak-power plant.

The advantage of demand response is that it delivers extra capacity immediately without having to build a new power plant or creating a new source of pollution.

TVA has hired Boston-based energy supplier EnerNOC Inc. to run the program for an undisclosed amount. EnerNOC manages similar programs for utilities from New England to Florida to California.

TVA executive Joe Hoagland says the program fits with the agency's new energy-efficiency and conservation initiative aimed at saving 1,400 megawatts by 2012 - roughly one new nuclear reactor - while also reducing the $1 billion TVA is spending annually to buy extra power from outside suppliers to meet peak needs.

AWG and other participants were called on six times last year, averaging outages of 5 hours each.

"I think it is an area where there is a lot of low-hanging fruit," Hoagland said of the potential reserves among smaller commercial operators - from grocery stores to office buildings.

The U.S. Department of Energy estimates the nation's demand response potential in 2004 was about 20,500 megawatts, or about 3 percent of U.S. peak demand. But the actual delivered reductions were about 9,000 megawatts, or 1.3 percent of peak demand.

PJM Interconnection, a Pennsylvania-based power grid manager serving utilities in 13 states, has developed a program similar to TVA's that has some 600 megawatts of demand response capacity under contract.

"It is good for everybody," PJM spokesman Ray Dotter said. "All of this just makes sense for economics, for reliability and for the environment."

TVA's program is seeking companies willing to accept outages of up to eight hours at a time on a 30-minute notice, with a total of 40 or 80 hours of outages during the June 1-Sept. 1 program period. Companies will be paid to be on-call and for actual energy savings during outages. A 1-megawatt commitment can earn the participating company $18,000 to $40,000 a year.

"If it is successful, my goal is to make it bigger," Hoagland said. "But we want to make sure that it really works right first."

Saskatchewan to credit solar panel owners, but not as much as old program did

Saskatchewan Solar Net Metering Program lets rooftop solar users offset at retail rate while earning 7.5 cents/kWh credits for excess energy; rebates are removed, SaskPower balances grid costs with a 100 kW cap.

 

Key Points

An updated SaskPower plan crediting rooftop solar at 7.5 cents/kWh, offsetting usage at retail rate, without rebates.

✅ Excess energy credited at 7.5 cents/kWh

✅ Offsets on-site use at retail electricity rates

✅ Up to 100 kW generation; no program capacity cap

 

Saskatchewan has unveiled a new program that credits electricity customers for generating their own solar power, but it won’t pay as much as an older program did or reimburse them with rebates for their costs to buy and install equipment.

The new net metering program takes effect Nov. 1, and customers will be able to use solar to offset their own power use at the retail rate, similar to UK households' right to sell power in comparable schemes, though program details differ.

But they will only get 7.5 cents per kilowatt hour credit on their bills for excess energy they put back into the grid, as seen in Duke Energy payment changes in other jurisdictions, rather than the 14 cents in the previous program.

Dustin Duncan, the minister responsible for Crown-owned SaskPower, says the utility had to consider the interests of people wanting to use rooftop solar and everyone else who doesn’t have or can’t afford the panels, who he says would have to make up for the lost revenue.

Duncan says the idea is to create a green energy option, with wind power gains highlighting broader competitiveness, while also avoiding passing on more of the cost of the system to people who just cannot afford solar panels of their own.

Customers with solar panels will be allowed to generate up to 100 kilowatts of power against their bills.

“It’s certainly my hope that this is going to provide sustainability for the industry, as illustrated by Alberta's renewable surge creating jobs, that they have a program that they can take forward to their potential customers, while at the same time ensuring that we’re not passing onto customers that don’t have solar panels more cost to upkeep the grid,” Duncan said Tuesday.

Saskatchewan NDP leader Ryan Meili said he believes eliminating the rebate and cutting the excess power credit will kill the province’s solar energy, a concern consistent with lagging solar demand in Canada in recent national reports, he said.

“(Duncan) essentially made it so that any homeowner who wants to put up panels would take up to twice as long to pay it back, which effectively prices everybody in the small part of the solar production industry — the homeowners, the farms, the small businesses, the small towns — out of the market,” Meili said.

The province’s old net metering program hit its 16 megawatt capacity ahead of schedule, forcing the program to shut down, while disputes like the Manitoba Hydro solar lawsuit have raised questions about program management elsewhere. It also had a rebate of 20 per cent of the cost of the system, but that rebate has been discontinued.

The new net metering program won’t have any limit on program capacity, or an end date.

According to Duncan, the old program would have had a net negative impact to SaskPower of about $54 million by 2025, but this program will be much less — between $4 million and $5 million.

Duncan said other provinces either have already or are in the process of moving away from rebates for solar equipment, including Nova Scotia's proposed solar charge and similar reforms, and away from the one-to-one credits for power generation.

Iran turning thermal power plants to combined cycle to save energy

Iran Combined-Cycle Power Plants drive energy efficiency, cut greenhouse gases, and expand megawatt capacity by converting thermal units; MAPNA-led upgrades boost grid reliability, reduce fuel use, and accelerate electricity generation growth nationwide.

 

Key Points

Upgraded thermal plants that reuse waste heat to boost efficiency, cut emissions, and add capacity to Iran's grid.

✅ 27 thermal plants converted; 160 more viable units identified

✅ Adds 12,600 MW capacity via heat recovery steam generators

✅ Combined-cycle share: 31.2% of 80.509 GW capacity

 

Iran has turned six percent of its thermal power plans into combined cycle plants in order to reduce greenhouse gases and save energy, with potential to lift thermal plants' PLF under rising demand, IRNA reported, quoting an energy official.

According to the MAPNA Group’s Managing Director Abbas Aliabadi, so far 27 thermal power plants have been converted to combined-cycle ones, aligning with Iran’s push to transmit power to Europe as a regional hub.

“The conversion of a thermal power plant to a combined cycle one takes about one to two years, however, it is possible for us to convert all the country’s thermal power plants into combined cycle plants over a five-year period.

Currently, a total of 478 thermal power plants are operating throughout Iran, of which 160 units could be turned into combined cycle plants. In doing so, 12,600 megawatts will be added to the country’s power capacity, supporting ongoing exports such as supplying a large share of Iraq's electricity under existing arrangements.

Related cross-border work includes deals to rehabilitate Iraq's power grid that support future exchanges.

As reported by IRNA on Wednesday, Iran’s Nominal electricity generation capacity has reached 80,509 megawatts (80.509 gigawatts), and it is deepening energy cooperation with Iraq to bolster regional reliability. The country increased its electricity generation capacity by 500 megawatts (MW) compared to the last year (ended on March 20).

Currently, with a total generation capacity of 25,083 MW (31.2 percent) combined cycle power plants account for the biggest share in the country’s total power generation capacity followed by gas power plants generating 29.9 percent, amid global trends where renewables are set to eclipse coal and regional moves such as Israel's coal reduction signal accelerating shifts.

Hydro wants B.C. residents to pay an extra $2 a month for electricity

BC Hydro Rate Increase proposes a 2.3% hike from April, with BCUC review, aligning below inflation and funding clean energy, electrification, and grid upgrades across British Columbia while keeping electricity prices among North America's lowest.

 

Key Points

A proposed 2.3% BC Hydro hike from April, under BCUC review, funds clean energy and keeps average bills below inflation.

✅ Adds about $2 per month to average residential bill

✅ Sixth straight increase below inflation since 2018

✅ Supports renewable projects and grid modernization

 

The British Columbia government says the province’s Crown power utility is applying for a 2.3-per-cent rate increase starting in April, with higher BC Hydro rates previously outlined, adding about $2 a month to the average residential bill.

A statement from the Energy Ministry says it’s the sixth year in a row that BC Hydro has applied for an increase below the rate of inflation, similar to a 3 per cent rise noted in a separate approval, which still trailed inflation.

It says rates are currently 15.6 per cent lower than the cumulative rate of inflation over the last seven years, starting in 2017-2018, with a provincial rate freeze among past measures, and 12.4 per cent lower than the 10-year rates plan established by the previous government in 2013.

The ministry says the “modest” rate increase application comes after consideration of a variety of options and their long-term impacts, including scenarios like a 3.75% two-year path evaluated alongside others, and the B.C. Utilities Commission is expected to decide on the plan by the end of February.

Chris O’Riley, president of BC Hydro, says the rates application would keep electricity costs in the province among the lowest in North America, even as a BC Hydro fund surplus prompted calls for changes, while supporting investments in clean energy to power vehicles, homes and businesses.

Energy Minister Josie Osborne says it’s more important than ever to keep electricity bills down, especially as Ontario hydro rates increase in a separate jurisdiction, as the cost of living rises at rates that are unsustainable for many.

“Affordable, stable BC Hydro rates are good for people, businesses and climate as we work together to power our growing economy with renewable energy instead of fossil fuels,” Osborne says in a statement issued Monday.

Earlier this year, the ministry said BC Hydro provided $315 million in cost-of-living bill credits, while in another province Manitoba Hydro scaled back an increase to ease pressure, to families and small businesses in the province, including those who receive their electricity service from FortisBC or a municipal utility.

COVID-19 crisis shows need to keep electricity options open, says Birol

Electricity Security and Firm Capacity underpin reliable supply, balancing variable renewables with grid flexibility via gas plants, nuclear power, hydropower, battery storage, and demand response, safeguarding telework, e-commerce, and critical healthcare operations.

 

Key Points

Ability to meet demand by combining firm generation and flexible resources, keeping grids stable as renewables grow.

✅ Balances variable renewables with dispatchable generation

✅ Rewards flexibility via capacity markets and ancillary services

✅ Enhances grid stability for critical loads during low demand

 

The huge disruption caused by the coronavirus crisis, and the low-carbon electricity lessons drawn from it, has highlighted how much modern societies rely on electricity and how firm capacity, such as that provided by nuclear power, is a crucial element in ensuring supply, International Energy Agency (IEA) Executive Director Fatih Birol said.

In a commentary posted on LinkedIn, Birol said: "The coronavirus crisis reminds us of electricity's indispensable role in our lives. It's also providing insights into how that role is set to expand and evolve in the years and decades ahead."

Reliable electricity supply is crucial for teleworking, e-commerce, operating ventilators and other medical equipment, among all its other uses, he said, adding that the hundreds of millions of people who live without any access to electricity are far more vulnerable to disease and other dangers.

"Although new forms of short-term flexibility such as battery storage are on the rise, and initiatives like UK home virtual power plants are emerging, most electricity systems rely on natural gas power plants - which can quickly ramp generation up or down at short notice - to provide flexibility, underlining the critical role of gas in clean energy transitions," Birol said.

"Today, most gas power plants lose money if they are used only from time to time to help the system adjust to shifts in demand. The lower levels of electricity demand during the current crisis are adding to these pressures. Hydropower, an often forgotten workhorse of electricity generation, remains an essential source of flexibility.

"Firm capacity, including nuclear power in countries that have chosen to retain it as an option, is a crucial element in ensuring a secure electricity supply even as soaring electricity and coal use complicate transitions. Policy makers need to design markets that reward different sources for their contributions to electricity security, which can enable them to establish viable business models."

In most economies that have taken strong confinement measures in response to the coronavirus - and for which the IEA has available data - electricity demand has declined by around 15%, largely as a result of factories and businesses halting operations, and in New York City load patterns were notably reshaped during lockdowns. If electricity demand falls quickly while weather conditions remain the same, the share of variable renewables like wind and solar can become higher than normal, and low-emissions sources are set to cover almost all near-term growth.

"With weaker electricity demand, power generation capacity is abundant. However, electricity system operators have to constantly balance demand and supply in real time. People typically think of power outages as happening when surging electricity demand overwhelms supply. But in fact, some of the most high-profile blackouts in recent times took place during periods of low demand," Birol said.

"When electricity from wind and solar is satisfying the majority of demand, and renewables poised to eclipse coal by 2025 are reshaping the mix, systems need to maintain flexibility in order to be able to ramp up other sources of generation quickly when the pattern of supply shifts, such as when the sun sets. A very high share of wind and solar in a given moment also makes the maintenance of grid stability more challenging."

Let’s make post-COVID Canada a manufacturing hub again

Canada Manufacturing Policy prioritizes affordable energy, trims carbon taxes, aligns with Buy America, and supports the resource sector, PPE and plastics supply, nearshoring, and resilient supply chains amid COVID-19, correcting costly green energy policies.

 

Key Points

A policy to boost industry with affordable energy, lower carbon taxes, resource ties, and aligned U.S. trade.

✅ Cuts energy costs and carbon tax burdens for competitiveness

✅ Rebuilds resource-sector linkages and domestic supply chains

✅ Seeks Buy America relief and clarity on plastics regulation

 

By Jocelyn Bamford

Since its inception in 2017, the Coalition of Concerned Manufacturers and Businesses has warned all levels of government that there would be catastrophic effects if policies that drove both the manufacturing and natural resources sectors out of the country were adopted.

The very origins of our coalition was in the fight for a competitive landscape in Ontario, a cornerstone of which is affordable energy and sounding the alarm that the Green Energy Policy in Ontario pushed many manufacturers out of the province.


The Green Energy Policy made electricity in Ontario four times the average North American rate. These unjust prices were largely there to subsidize the construction of expensive and inefficient wind and solar energy infrastructure, even as cleaning up Canada's grid is cited as critical to meeting climate pledges.

My company’s November hydro bill was $55,000 and $36,500 of that was the so-called global adjustment charge, the name given to these green energy costs.

Unaffordable electricity, illustrated by higher Alberta power costs in recent years, coupled with ever-more burdensome carbon taxes, have pushed Canadian manufacturing into the open arms of other countries that see the importance of affordable energy to attract business.

One can’t help but ask the question: If Canada had policies that attracted and maintained a robust manufacturing sector, would we be in the same situation with a lack of personal protective equipment and medical supplies for our front-line medical workers and our patients during this pandemic?  If our manufacturing sector wasn’t crippled by taxes and regulation, would it be more nimble and able to respond to a national emergency?

It seems that the federal government’s policies are designed to push manufacturing out, stifle our resource sector, and kill the very plastics industry that is so essential to keeping our front-line medical staff, patients, and citizens safe, even as the net-zero race accelerates federally.

As the federal government chased its obsession with a new green economy – a strange obsession given our country’s small contribution to global GHGs – including proposals for a fully renewable grid by 2030 advocated by some leaders, it has been blinded from the real threats to our country, threats that became very, very real with COVID-19.

After the pandemic has passed, the federal government must work to make Canada manufacturing and resource friendly again, recognizing that the IEA net-zero electricity report projects the need for more power. COVID-19 proves that Canada relies on a robust resource economy and manufacturing sector to survive. We need to ensure that we are prepared for future crises like the one we are facing now.

Here are five things our government can do now to meet that end:

1. End all carbon taxes immediately.

2. Create a mandate to bring manufacturing back to Canada through competitive offerings and favourable tax regimes.

3. Recognize the interconnections between the resource sector and manufacturing, including how fossil-fuel workers support the transition across supply chains. Many manufacturers supply parts and pieces to the resource sector, and they rely on affordable energy to compete globally.

4. Stop the current federal government initiative to label plastic as toxic. At a time when the government is appealing to manufacturers to re-tool and produce needed plastic products for the health care sector, labelling plastics as toxic is counterproductive.

5. Work to secure a Canadian exemption to Buy America. This crisis has clearly shown us that dependency on China is dangerous. We must forge closer ties with America and work as a trading block in order to be more self-sufficient.

These are troubling times. Many businesses will not survive.

We need to take back our manufacturing sector.  We need to take back our resource sector.

We need to understand the interconnected nature of these two important segments of our gross domestic production, and opportunities like an Alberta–B.C. grid link to strengthen reliability.
If we do not, in the next pandemic we may find ourselves not only without ventilators, masks and gowns but also without energy to operate our hospitals.

Jocelyn Bamford is a Toronto business executive and President of the Coalition of Concerned Manufacturers and Businesses of Canada

Perry presses ahead on advanced nuclear reactors

Advanced Nuclear Reactors drive U.S. clean energy with small modular reactors, a new test facility at Idaho National Laboratory, and public-private partnerships accelerating nuclear innovation, safety, and cost reductions through DOE-backed programs and university simulators.

 

Key Points

Advanced nuclear reactors are next-gen designs, including SMRs, offering safer, cheaper, low-carbon power.

✅ DOE test facility at Idaho National Laboratory

✅ Small modular reactors with passive safety systems

✅ University simulators train next-gen nuclear operators

 

Energy Secretary Rick Perry is advancing plans to shift the United States towards next-gen nuclear power reactors.

The Energy Department announced this week it has launched a new test facility at the Idaho National Laboratory where private companies can work on advanced nuclear technologies, as the first new U.S. reactor in nearly seven years starts up, to avoid the high costs and waste and safety concerns facing traditional nuclear power plants.

“[The National Reactor Innovation Center] will enable the demonstration and deployment of advanced reactors that will define the future of nuclear energy,” Perry said.

With climate change concerns growing and net-zero emissions targets emerging, some Republicans and Democrats are arguing for the need for more nuclear reactors to feed the nation’s electricity demand. But despite nuclear plants’ absence of carbon emissions, the high cost of construction, questions around what to do with the spent nuclear rods and the possibility of meltdown have stymied efforts.

A new generation of firms, including Microsoft founder Bill Gates’ Terra Power venture, are working on developing smaller, less expensive reactors that do not carry a risk of meltdown.

“The U.S. is on the verge of commercializing groundbreaking nuclear innovation, and we must keep advancing the public-private partnerships needed to traverse the dreaded valley of death that all too often stifles progress,” said Rich Powell, executive director of ClearPath, a non-profit advocating for clean energy and green industrial strategies worldwide.

The new Idaho facility is budgeted at $5 million under next year’s federal budget, even as the cost of U.S. nuclear generation has fallen to a ten-year low, which remains under negotiation in Congress.

On Thursday another advanced nuclear developer working on small modular systems, Oregon-based NuScale Power, announced it was building three virtual nuclear control rooms at Texas A&M University, Oregon State University and the University of Idaho, with funding from the Energy Department.

The simulators will be open to researchers and students, to train on the operation of smaller, modular reactors, as well as the general public.

NuScale CEO John Hopkins said the simulators would “help ensure that we educate future generations about the important role nuclear power and small modular reactor technology will play in attaining a safe, clean and secure energy future for our country.”
