Otter Tail Power Co.'s North Dakota customers will see higher electric bills as the utility adds more wind power to its energy sources, state regulators say.

Beginning September 1, a separate charge assessed to ratepayers to pay for Otter Tail wind energy projects will increase the monthly bill by almost $1.40 for a residential customer who uses 750 kilowatt-hours of electricity, state Public Service Commission filings say.

For that customer, the wind energy charge would rise from $2.76 monthly to $4.13, an increase of almost 50 percent. The "renewable energy rider" is listed separately on customers' bills.

Commissioner Tony Clark said the charge is intended to allow Otter Tail Power to begin recouping development costs for wind projects. But it does have its drawbacks, Clark said.

"It makes wind perhaps look a little boutique, or that we're treating it a little different," he said. "It's certainly not intended to be that way."

Fergus Falls, Minn.-based Otter Tail Power has about 57,000 North Dakota electric customers. It serves the cities of Wahpeton, Devils Lake and Jamestown, as well as a number of rural communities.

About 18 percent of the utility's electricity comes from wind turbines, including power that Otter Tail buys from other sources, company spokeswoman Cris Kling said Thursday. Almost three-quarters of its power is generated by coal-fueled plants.

Otter Tail owns part of wind energy projects that were recently built near Langdon, in North Dakota's northeast corner, and Lake Ashtabula, near Valley City in Barnes County. The utility owns 40.5 megawatts of the Langdon wind farm's generating capacity, and 48 megawatts from the Lake Ashtabula project.

The completion of a third wind project, six miles north of Luverne in Griggs County, in east-central North Dakota, made another increase in the wind-energy charge necessary, Kling said.

Otter Tail owns 49.5 megawatts of the Luverne development, which is capable of generating 169.5 megawatts and began operating almost a year ago. Its majority owner is NextEra Energy Resources of Juno Beach, Fla., a company formerly known as FPL Energy.

Clark said the separate renewable energy charge may give customers a misleading picture about their electricity costs.

If Otter Tail did not develop wind energy supplies, the utility would probably have to buy power on the open market during times of high demand, Clark said. However, the savings it realizes from wind power are lumped with a general monthly adjustment on fuel costs that are part of customers' electric bills and are not specifically listed, he said.

OPINION Rewiring Indian electricity

India Power Sector Crisis: a tangled market of underused plants, coal shortages, cross-subsidies, high transmission losses, and weak PPAs, requiring deregulation, power exchanges, and cost-reflective tariffs to fix insolvency and outages.

 

Key Points

India power market failure from subsidies, coal shortages, and losses, needing deregulation and reflective pricing.

✅ Deregulate to enable spot trading on power exchanges

✅ End cross-subsidies; charge cost-reflective tariffs

✅ Secure coal supply; cut T&D losses and theft

 

India's electricity industry is in a financial and political tangle.

Power producers sit on thousands of megawatts of underutilized plant, while consumers face frequent power cuts, both planned and unplanned.

Financially troubled generators struggle to escape insolvency proceedings. The state-owned banks that have mostly financed power utilities fear that debts of troubled utilities totaling 1.74 trillion rupees will soon go bad.

Aggressive bidding for supply contracts and slower-than-expected demand growth, including a recent demand slump in electricity use, is the root cause. The problems are compounded by difficulties in securing coal and other fuels, high transmission losses, electricity theft and cash-starved distribution companies.

But India's 36 state and union territory governments are contributing mightily to this financial and economic mess. They persist with populist cross-subsidies -- reducing charges for farmers and households at the cost of nonagricultural businesses, especially energy-intensive manufacturing sectors such as steel.

The states refuse to let go of their control over how electricity is produced, distributed and consumed. And they are adamant that true markets, with freedom for large industrial users to buy power at market-determined rates from whichever utility they want at power exchanges -- will not become a reality in India.

State politicians are driven mainly by the electoral need to appease farmers, India's most important vote bank, who have grown used to decades of nearly-free power.

New Delhi is therefore relying on short-term fixes instead of attempting to overhaul a defunct system. Users must pay the real cost of their electricity, as determined by a properly integrated national market free of state-level interference if India's power mess is to be really addressed.

As of Aug. 31, the country's total installed production capacity was 344,689 MW, underscoring its status as the third-largest electricity producer globally by output. Out of that, thermal power comprising coal, gas and diesel accounted for 64%, hydropower 13% and renewables accounted for 20%. Commercial and industrial users accounted for 55% of consumption followed by households on 25% and the remaining 20% by agriculture.

Coal-fired power generation, which contributes roughly 90% of thermal output and the bulk of the financially distressed generators, is the most troubled segment as it faces a secular decline in tariffs due to increasing competition from highly subsidized renewables (which also benefit from falling solar panel costs), coal shortages and weak demand.

The Central Electricity Act (CEA) 2003 opened the gates of the country's power sector for private players, who now account for 45% of generating capacity.

But easy credit, combined with an overconfident estimation of the risks involved, emboldened too many investors to pile in, without securing power purchase agreements (PPAs) with distribution companies.

As a result, power capacity grew at an annual compound rate of 11% compared to demand at 6% in the last decade leading to oversupply.

This does not mean that the electricity market is saturated. Merely that there are not enough paying customers. Distributors have plenty of consumers who will not or cannot pay, even though they have connections. There is huge unmet demand for power. There are 32 million Indian homes -- roughly 13% of the total -- mostly rural and poor with no access to electricity.

Moreover, consumption by those big commercial and industrial users which do not enjoy privileged rates is curbed by high prices, driven up by the cost of subsidizing others, extra charges on exchange-traded power and transmission and distribution losses (including theft) of 20-30%.

With renewables increasingly becoming cheaper, financially stressed distributors are avoiding long-term power purchase agreements, preferring spot markets. Meanwhile, coal shortages force generators to buy expensive imported coal supplies or cut output. The operating load for most private generators, which suffer particularly acute coal shortages in compared to state-owned utilities, has fallen from 84% in 2009-2010 to 55% now.

Smoothing coal supplies should be the top priority. Often coal is denied to power generators without long-term purchase contracts. Such discrimination in coal allocation prevails -- because the seller (state-run Coal India and its numerous subsidiaries) is an inefficient monopolist which cannot produce enough and rations coal supplies, favoring state-run generators over private.

To help power producers, New Delhi plans measures including auctioning power sales contracts with assured access to coal. However, even though coal and electricity shortages eased recently, such short-term fixes won't solve the problem. With electricity prices in secular decline, distributors are not seeking long-term supply contracts -- rather they are often looking for excuses to get out of existing agreements.

India needs a fundamental two-step reform. First, the market must be deregulated to allow most bulk suppliers and users to move to power trading exchanges, which currently account for just 10% of the market.

This would lead to genuine price discovery in a spot market and, in time, lead to the trading of electricity futures contracts. That would help in consumers and producers hedge their respective costs and revenues and safeguard their economic positions without any need for government intervention.

The second step to a healthy electricity industry is for consumers to pay the real cost of power. Cross-subsidization must end. That would promote optimal electricity use, innovation and environmental protection. Farmers enjoying nearly-free power create ecological problems by investing in water-guzzling crops such as rice and sugar cane.

Most industrial consumers, who do not have power supply privileges, have their businesses distorted and delayed by high prices. Lowering their costs would encourage power-intensive manufacturing to expand, and in the process, boost electricity demand and improve capacity utilization.

Of course, cutting theft is central to making consumers pay their way. Government officials must stop turning a blind eye to theft, especially when such transmission and distribution losses average 20%.

Politicians who want to continue subsidizing farmers or assist the poor can do so by paying cash out directly to their bank accounts, instead of wrongly relying on the power sector.

Such market-oriented reforms have long been blocked by state-level politicians, who now enjoy the influence born of operating subsidies and interfering in the sector. New Delhi must address this opposition. Narendra Modi, as a self-styled reforming prime minister, should have the courage to bite this bullet and convince state governments (starting with those ruled by his Bharatiya Janata Party) to reform. To encourage cooperation, he could offer states securing real improvements an increased share of centrally collected taxes.

Ritesh Kumar Singh is to be the chief economist of the new policy research and advocacy company Indonomics Consulting. He is former assistant director of the Finance Commission of India.

TransAlta Poised to Finalize Alberta Data Centre Agreement in 2025 

TransAlta Alberta Data Centre integrates AI, cloud computing, and renewable energy, tackling electricity demand, grid capacity, decarbonization, and energy storage with clean power, cooling efficiency, and PPA-backed supply for hyperscale workloads.

 

Key Points

TransAlta Alberta Data Centre is a planned AI facility powered mostly by renewables to meet high electricity demand.

✅ Targets partner exclusivity mid-year; ops 18-24 months post-contract.

✅ Supplies ~90% power via TransAlta; balance from market.

✅ Anchors $3.5B clean energy growth and storage in Alberta.

 

TransAlta Corp., one of Alberta’s leading power producers, is moving toward finalizing agreements with partners to establish a data centre in the province, aligned with AI data center grid integration efforts nationally, aiming to have definitive contracts signed before the end of the year.

CEO John Kousinioris stated during an analyst conference that the company seeks to secure exclusivity with key partners by mid-year, with detailed design plans and final agreements expected by late 2025. Once the contracts are signed, the data centre is anticipated to be operational within 18 to 24 months, a horizon mirrored by Medicine Hat AI grid upgrades initiatives that aim to modernize local systems.

Data centres, which are critical for high-tech industries such as artificial intelligence, consume large amounts of electricity to run and cool servers, a trend reflected in U.S. utility power challenges reporting, underscoring the scale of energy demand. In this context, TransAlta plans to supply around 90% of its partner's energy needs for the facility, with the remainder coming from the broader electricity market.

Alberta has identified data centres as a strategic priority, aiming to see $100 billion in AI-related data centre construction over the next five years. However, the rapid growth of this sector presents challenges for the region’s energy infrastructure. Electricity demand from data centres has already outpaced the available capacity in Alberta’s power grid, intensifying discussions about a western Canadian electricity grid to improve regional reliability, potentially impacting the province’s decarbonization goals.

To address these challenges, TransAlta has adopted a renewable energy investment strategy. The company announced a $3.5 billion growth plan focused primarily on clean electricity generation and storage, as British Columbia's clean energy shift advances across the region, through 2028. By then, more than two-thirds of TransAlta’s earnings are expected to come from renewable power generation, supporting progress toward a net-zero electricity grid by 2050 nationally.

The collaboration between TransAlta and data centre developers represents an opportunity to balance growing energy demand with sustainability goals. By integrating renewable energy generation into data centre operations and broader macrogrid investments, Alberta could move toward a cleaner and more resilient energy future.

✅ Upgrade transmission, distribution, and adopt liquid cooling efficiency

 

Artificial intelligence (AI) is revolutionizing various sectors, driving demand for data centers that support AI applications. In Canada, this surge in data center development presents both economic opportunities and challenges for the electricity grid, where utilities using AI to adapt to evolving demand dynamics. Integrating AI-focused data centers into Canada's electricity infrastructure requires strategic planning to balance economic growth with sustainable energy practices.​

Economic and Technological Incentives

Canada has been at the forefront of AI research for over three decades, establishing itself as a global leader in the field. The federal government has invested significantly in AI initiatives, with over $2 billion allocated in 2024 to maintain Canada's competitive edge and to align with a net-zero grid by 2050 target nationwide. Provincial governments are also actively courting data center investments, recognizing the economic and technological benefits these facilities bring. Data centers not only create jobs and stimulate local economies but also enhance technological infrastructure, supporting advancements in AI and related fields.​

Challenges to the Electricity Grid

However, the energy demands of AI data centers pose significant challenges to Canada's electricity grid, mirroring the power challenge for utilities seen in the U.S., as demand rises. The North American Electric Reliability Corporation (NERC) has raised concerns about the growing electricity consumption driven by AI, noting that the current power generation capacity may struggle to meet this increasing demand, while grids are increasingly exposed to harsh weather conditions that threaten reliability as well. This situation could lead to reliability issues, including potential blackouts during peak demand periods, jeopardizing both economic activities and the progress of AI initiatives.​

Strategic Integration Approaches

To effectively integrate AI data centers into Canada's electricity grids, a multifaceted approach is essential:

  1. Diversifying Energy Sources: Relying solely on traditional energy sources may not suffice to meet the heightened demands of AI data centers. Incorporating renewable energy sources, such as wind, solar, and hydroelectric power, can provide sustainable alternatives. For instance, Alberta has emerged as a proactive player in supporting AI-enabled data centers, with the TransAlta data centre agreement expected to advance this momentum, leveraging its renewable energy potential to attract such investments.
     

  2. Implementing Energy Storage Solutions: Integrating large-scale battery storage systems can help manage the intermittent nature of renewable energy. These systems store excess energy generated during low-demand periods, releasing it during peak times to stabilize the grid. In some communities, AI-driven grid upgrades complement storage deployments to optimize operations, which supports data center needs and community reliability.
     

  3. Enhancing Grid Infrastructure: Upgrading transmission and distribution networks is crucial to handle the increased load from AI data centers. Strategic investments in grid infrastructure can prevent bottlenecks and ensure efficient energy delivery, including exploration of macrogrids in Canada to improve regional transfers, supporting both existing and new data center operations.​
     

  4. Adopting Energy-Efficient Data Center Designs: Designing data centers with energy efficiency in mind can significantly reduce their power consumption. Innovations such as liquid cooling systems are being explored to manage the heat generated by high-density AI workloads, offering more efficient alternatives to traditional air cooling methods.

  5. Establishing Collaborative Policies: Collaboration among government entities, utility providers, and data center operators is vital to align energy policies with technological advancements. Developing regulatory frameworks that incentivize sustainable practices can guide the growth of AI data centers in harmony with grid capabilities.​
     

Integrating AI data centers into Canada's electricity grids presents both significant opportunities and challenges. By adopting a comprehensive strategy that includes diversifying energy sources, implementing advanced energy storage, enhancing grid infrastructure, promoting energy-efficient designs, and fostering collaborative policies, Canada can harness the benefits of AI while ensuring a reliable and sustainable energy future. This balanced approach will position Canada as a leader in both AI innovation and sustainable energy practices.

Switch from fossil fuels to electricity could cost $1.4 trillion, Canadian Gas Association warns

Canada Electrification Costs: report estimates $580B-$1.4T to scale renewable energy, wind, solar, and storage capacity to 2050, shifting from natural gas toward net-zero emissions and raising average household energy spending by $1,300-$3,200 annually.

 

Key Points

Projected national expense to expand renewables and electrify energy systems by 2050, impacting household energy bills.

✅ $580B-$1.4T forecast for 2020-2050 energy transition

✅ 278-422 GW wind, solar, storage capacity by 2050

✅ Household costs up $1,300-$3,200 per year on average

 

The Canadian Gas Association says building renewable electricity capacity to replace just half of Canada's current fossil fuel-generated energy, a shift with significant policy implications for grids across provinces, could increase national costs by as much as $1.4 trillion over the next 30 years.

In a report, it contends, echoing an IEA report on net-zero, that growing electricity's contribution to Canada's energy mix from its current 19 per cent to about 60 per cent, a step critical to meeting climate pledges that policymakers emphasize, will require an expansion from 141 gigawatts today to between 278 and 422 GW of renewable wind, solar and storage capacity by 2050.

It says that will increase national energy costs by between $580 billion and $1.4 trillion between 2020 and 2050, a projection consistent with recent reports of higher electricity prices in Alberta amid policy shifts, translating into an average increase in Canadian household spending of $1,300 to $3,200 per year.

The study, prepared by consulting firm ICF for the association, assumes electrification begins in 2020 and is applied in all feasible applications by 2050, with investments in the electricity system, guided by the implications of decarbonizing the grid for reliability and cost, proceeding as existing natural gas and electric end use equipment reaches normal end of life.

Association CEO Tim Egan says the numbers are "pretty daunting" and support the integration of natural gas with electric, amid Canada's race to net-zero commitments, instead of using an electric-only option as the most cost-efficient way for Canada to reach environmental policy goals.

But Keith Stewart, senior energy strategist with Greenpeace Canada, says scientists are calling for the world to get to net-zero emissions by 2050, and Canada's net-zero by 2050 target underscores that urgency to avoid "catastrophic" levels of warming, so investing in natural gas infrastructure to then shut it down seems a "very expensive option."

Hydro One: No cut in peak hydro rates yet for self-isolating customers

Hydro One COVID-19 Rate Relief responds to time-of-use pricing, peak rates, and Ontario Energy Board rules as residents stay home, offering a Pandemic Relief Fund, flexible payments, and support for electricity bills amid off-peak adjustments.

 

Key Points

Hydro One's COVID-19 rate relief includes payment flexibility and hardship aid to ease time-of-use bill burdens.

✅ Advocates flexibility on time-of-use and peak rate impacts

✅ Pandemic Relief Fund offers aid and payment options

✅ OEB sets prices; utilities relay concerns and support

 

Hydro One says it is listening to requests by self-isolating residents for reduced kilowatt hour peak rates during the day when most people are home riding out the COVID-19 pandemic.

Peak rates of 20.8 cents per kw/h are twice as high from 7 a.m. to 7 p.m. – except weekends – than off-peak rates of 10.1 cents per kw/h and set by the Ontario Energy Board and not electricity providers such as Hydro One and Elexicon (formerly Veridian).

Frustrated electrical customers have signed their John Henry’s more than 50,000 times to a change.org petition demanding Hydro One temporarily slash rates for those already struggling with work closures and loss of income amid concerns about a potential recovery rate that could raise bills.

Alex Stewart, media relations spokesman for Hydro One, said the corporation is working toward a solution.

“While we are regulated to adhere to time-of-use pricing by the Ontario Energy Board, we’ve heard the concerns about time-of-use pricing and the idea of a fixed COVID-19 hydro rate as many of our customers will stay home to stop the spread of COVID-19,” Stewart told The Intelligencer.

“We continue to advocate for greater choice during this difficult time and are working with everyone in the electricity sector to ensure our customers are heard.”

Stewart said the electricity provider is reaching out to customers to help them during a difficult self-isolating and social distancing period in other ways to bring financial relief.

For example, new hardship measures are now in play by Hydro One to give customers some relief from ballooning electricity bills.

“This is a difficult time for everyone. Hydro One has launched a new Pandemic Relief Fund to support customers affected by the novel coronavirus COVID-19. As part of our commitment to customers, we will offer financial assistance, as well as increased payment flexibility, to customers experiencing hardship,” Stewart said.

“Hydro One is also extending its Winter Relief program to halt disconnections and reconnections to customers experiencing hardship during the coldest months of the year. This is about doing the right thing and offering flexibility to our customers so they have peace of mind and can concentrate on what matters most – keeping their loved ones safe.”

Stewart said customers having difficult times can visit the company’s website for more details at www.HydroOne.com/ReliefFund.

Elexicon Energy, meanwhile, said earlier the former Veridian company is passing along concerns to the OEB but otherwise can’t lower the rates unless directed to do so, as occurred when the province set off-peak pricing temporarily.

Chris Mace, Elexicon corporate communications spokesperson, said, “We don’t have the authority to do that.

“The Ontario Energy Board sets the energy prices. This is in the Ministry of Energy’s hands. We at Elexicon, along with other local distribution companies (LDC), have shared this feedback with the ministry and OEB to come up with some sort of solution or alternative. But this is out of our hands. We can’t shift anything.”

He suggested residents can shift the use of higher-drawing electrical appliances to early morning before 7 or in the evening after 7 p.m. when ultra-low overnight rates may apply.

Families may want to be “mindful whether it be cooking or laundry and so on and holding off on doing those until off-peak hours take effect. We are hearing customers and we have passed along those concerns to the ministry and the OEB.”

Hydro One power tips

Certain electrical uses in the home consumer more power than others, as reflected in Ontario’s electricity cost allocation approach:

62 per cent goes to space heating
19 per cent goes to water heaters
13 per cent goes to appliances
2 per cent goes to space cooling

Michigan utilities propose more than $20M in EV charging programs

Michigan EV time-of-use charging helps DTE Energy and Consumers Energy manage off-peak demand, expand smart charger rebates, and build DC fast charging infrastructure, lowering grid costs, emissions, and peak load impacts across Michigan's distribution networks.

 

Key Points

Michigan utility programs using time-based EV rates to shift charging off-peak and ease grid load via charger rebates.

✅ Off-peak rates cut peak load and distribution transformer stress.

✅ Rebates support home smart chargers and DC fast charging sites.

✅ DTE Energy and Consumers Energy invest to expand EV infrastructure.

 

The two largest utilities in the state of Michigan, DTE Energy and Consumers Energy, are looking at time-of-use charging rates in two proposed electric vehicle (EV) charging programs, aligned with broader EV charging infrastructure trends among utilities, worth a combined $20.5 million of investments.

DTE Energy last month proposed a $13 million electric vehicle (EV) charging program, which would include transformer upgrades/additions, service drops, labor and contractor costs, materials, hardware and new meters to provide time-of-use charging rates amid evolving charging control dynamics in the market. The Charging Forward program aims to address customer education and outreach, residential smart charger support and charging infrastructure enablement, DTE told regulators in its 1,100-page filing. The utility requested that rebates provided through the program be deferred as a regulatory asset.

Consumers Energy in 2017 withdrew a proposal to install 800 electric vehicle charging ports in its Michigan service territory after questions were raised over how to pay for the $15 million plan. According to Energy News Network, the utility has filed a modified proposal building on the former plan and conversations over the last year that calls for approximately half of the original investment.

Utilities across the country are viewing new demand from EVs as a potential boon to their systems, a shift accelerated by the Model 3's impact on utility planning, potentially allowing greater utilization and lower costs. But that will require the vehicles to be plugged in when other demand is low, to avoid the need for extensive upgrades and more expensive power purchases. Michigan utilities' proposal focuses on off-peak EV charging, as well as on developing new EV infrastructure.

While adoption has remained relatively low nationally, last year the Edison Electric Institute and the Institute for Electric Innovation forecast 7 million EVs on United States' roads by the end of 2025. But unless those EVs can be coordinated, state power grids could face increased stress, the National Renewable Energy Laboratory has said distribution transformers may need to be replaced more frequently and peak load could push system limits — even with just one or two EVs on a neighborhood circuit. 

In its application, DTE told regulators that electrification of transportation offers a range of benefits including "reduced operating costs for EV drivers and affordability benefits for utility customers."

"Most EV charging takes place overnight at home, effectively utilizing distribution and generation capacity in the system during a low load period," the utility said. "Therefore, increased EV adoption puts downward pressure on rates by spreading fixed costs over a greater volume of electric sales."

DTE added that other benefits include reduced carbon emissions, improved air quality, increased expenditures in local economies and reduced dependency on foreign oil for the public at large.

A previous proposal from Consumers Energy included 60 fast charging DC stations along major highways in the Lower Peninsula and 750 240-volt AC stations in metropolitan areas. Consumers' new plan will offer rebates for charger installation, as U.S. charging networks jostle for position amid federal electrification efforts, including residential and DC fast-charging stations.
