Two companies will build a two-megawatt solar energy system at Denver International Airport.

WorldWater & Solar Technologies Corp. will design and build the system, which will be located at DIA's main terminal. MMA Renewable Ventures will own and operate the system and sell power to DIA under a long-term contract.

The system, which will be up and running next year, is expected to generate 3.5 million kilowatt-hours of electricity annually. The companies said that will reduce carbon emissions by more than 5 million pounds a year.

"DIA will benefit from a renewable energy system that is cost-effective from the day it becomes operational and for years to come," Matt Cheney, chief executive officer of MMA Renewable Ventures, said in a press release.

Hundreds facing hydro disconnection as bills pile up during winter ban

Ontario Hydro Disconnection Ban ends May 1, prompting utilities and Hydro One to push payment plans, address arrears, and link low-income assistance, as Sudbury officials urge customers to avoid spring electricity disconnections.

 

Key Points

A seasonal policy halting winter shutoffs in Ontario, ending May 1 as utilities emphasize payment plans and assistance.

✅ Disconnections resume after winter moratorium ends May 1.

✅ Utilities offer payment plans, arrears management, relief funds.

✅ Hydro One delays shutoffs until June 1; arrears down 60%.

 

The first of May has taken on new meaning this year in Ontario.

It's when the province's ban on hydro disconnections during the winter months comes to an end, even as Ontario considers extending moratoriums in some cases.

Wendy Watson, the director of communications at Greater Sudbury Utilities, says signs of the approaching deadline could be seen in their office of the past few weeks.

"We've had quite an active stream of people into our front office to catch up on their accounts and also we've had a lot of people calling us to make payment arrangements or pay their bill or deal with their arrears," she says.

Watson says there are 590 customers in Sudbury who could face possible disconnection this spring, compared with just 60 when the ban started in November.

"They will put off until tomorrow what they can avoid today," she says.

Watson says they are hoping to work with customers to figure payment plans with more choice and flexibility and avoid the need to cut power to certain homes and businesses. 

"As we like to say we're in the distribution of energy business, not the disconnection of energy business. We want you to be able to turn the lights on," she says.

Joseph Leblanc from the Social Planning Council of Sudbury says the winter hydro disconnection ban is one of several government measures that keep low income families on the brink of disaster. (CBC)

Hydro One executive vice-president of customer care Ferio Pugilese, whose utility later extended disconnection bans across its service area, tells a different story.

He says the company has worked hard to configure payment plans for customers over the last three years amid unchanged peak-rate policies and find ways for them to pay "that fit their lifestyle."

"The threat of a disconnection is not on its own something that's going to motivate someone to pay their bills," says Pugilese.

He says Hydro One is also sending out notices this spring, but won't begin cutting anyone off until June 1st.

He says that disconnections and the amount owing from outstanding bills to Hydro One are down 60 per cent in the last year. 

Ontario Energy Minister Glenn Thibeault says there is plenty of help from government programs and utility financing options like Hydro One's relief fund for those having trouble paying their power bills. (CBC)

Sudbury MPP and Energy Minister Glenn Thibeault says his hope is that people having trouble paying their power bills will talk to their hydro utility and look at the numerous programs the government offers to help low-income citizens.

"You know, I really want every customer to have a conversation with their local utility about getting back on track and we do have those programs in place," he says.

However, Joseph Leblanc, the executive director of the Social Planning Council of Sudbury, says the winter disconnection ban is just another government policy that keeps the poor on the brink of disaster.

"It's a feel good story for the government to say that, but it's a band-aid solution. We can stop the bleeding for a little while, make sure people aren't freezing to death in Ontario," he says. 

"People choose between rent, hydro, medicine, food, and there's an option for one of those to take some pressure off for a little while."

Instead, Leblanc would like to see the government fast track the province-wide implementation of the basic income program it's testing out in a few cities.

Imported coal volumes up 17% during Apr-Oct as domestic supplies shrink

India Thermal Power Coal Imports surged 17.6% as CEA-monitored plants offset weaker CIL and SCCL supplies, driven by Saubhagya-led electricity demand, regional power deficits, and varied consumption across Uttar Pradesh, Bihar, Maharashtra, and Gujarat.

 

Key Points

Fuel volumes imported for Indian thermal plants, tracked by CEA, reflecting shifts in CIL/SCCL supply, demand, and regional power deficits.

✅ Imports up 17.6% as domestic CIL/SCCL deliveries lag targets

✅ Saubhagya-driven demand lifts generation in key beneficiary states

✅ Industrial slowdowns cut usage in Maharashtra, Tamil Nadu, Gujarat

 

The receipt of imported coal by thermal power plants, where plant load factors have risen, has shot up by 17.6 per cent during April-October. The coal import volumes refer to the power plants monitored by the Central Electricity Authority (CEA), and come amid moves to ration coal supplies as electricity demand surges, a power update report from CARE Ratings showed.

Imports escalated as domestic supplies by Coal India Ltd (CIL) and another state run producer- Singareni Collieries Company Ltd (SCCL) dipped in the period, after earlier shortages that have since eased in later months. Rate of supplies by the two coal companies to the CEA monitored power stations stood at 80.4 per cent, indicating a shortfall of 19.6 per cent against the allocated quantity.

According to the study by CARE Ratings, total coal supplied by CIL and SCCL to the power sector stood at 315.9 million tonnes (mt) during April-October as against 328.5 mt in the comparable period of last fiscal year.

The study noted that growth in power generation during the April-October 2019, with India now the third-largest electricity producer globally, was on account of higher demand from Pradhan Mantri Sahaj Bijli Har Ghar Yojana or Saubhagya Scheme beneficiary states. Providing connection to households in order to achieve 100% per cent electrification has in part helped the sector avert de-growth, as part of efforts to rewire Indian electricity and expand access.

Large states namely Uttar Pradesh, Bihar, Punjab, West Bengal and Rajasthan have recorded over five per cent growth in consumption of power. These states along with Odisha, Madhya Pradesh and Assam accounted for 75 per cent of the beneficiaries under the Saubhagya Scheme (Household Electrification Scheme). The ongoing economic downturn has led to a sharp fall in electricity demand from industrialised states. Maharashtra, which is also the largest power consuming state in India, recorded a decline in consumption of 5.6 per cent.

Other states namely Tamil Nadu, Telangana, Gujarat and Odisha too recorded fall in power consumed, echoing global dips in daily electricity demand seen later during the pandemic. These states house large clusters of mining, automobile, cement and other manufacturing industries, and a decline in these sectors led to fall in demand for power across these states. - The demand-supply gap or power deficit has remained at 0.6 per cent during the April-October 2019. North-East reported 4.8 per cent of power deficit followed by Northern Region at 1.3 per cent. Within Northern Region, Jammu & Kashmir and Uttar Pradesh accounted for 65 per cent and 30 per cent respectively of the regions power supply deficit.

West Coast consumers won't benefit if Trump privatizes the electrical grid

BPA Privatization would sell the Bonneville Power Administration's transmission lines, raising FERC-regulated grid rates for ratepayers, impacting hydropower and the California-Oregon Intertie under the Trump 2018 budget proposal in the Pacific Northwest region.

 

Key Points

Selling Bonneville's transmission grid to private owners, raising rates and returns, shifting costs to ratepayers.

✅ Trump 2018 budget targets BPA transmission assets for sale.

✅ Higher capital costs, taxes, and profit would raise transmission rates.

✅ California-Oregon Intertie and hydropower flows face price impacts.

 

President Trump's 2018 budget proposal is so chock-full of noxious elements — replacing food stamps with "food boxes," drastically cutting Medicaid and Medicare, for a start — that it's unsurprising that one of its most misguided pieces has slipped under the radar.

That's the proposal to privatize the government-owned Bonneville Power Administration, which owns about three-quarters of the high-voltage electric transmission lines in a region that includes California, Washington state and Oregon, serving more than 13.5 million customers. By one authoritative estimate, any such sale would drive up the cost of transmission by 26%-44%.

The $5.2-billon price cited by the Trump administration, moreover, is nearly 20% below the actual value of the Bonneville grid — meaning that a private buyer would pocket an immediate windfall of $1.2 billion, at the expense of federal taxpayers and Bonneville customers.

Trump's plan for Portland, Ore.-based Bonneville is part of a larger proposal to sell off other government-owned electricity bodies, including the Colorado-based Western Area Power Administration and the Oklahoma-based Southwestern Power Administration. But Bonneville is by far the largest of the three, accounting for nearly 90% of the total $5.8 billion the budget anticipates collecting from the sales. The proposal is also part of the administration's

Both plans are said to be politically dead-on-arrival in Washington. But they offer a window into the thinking in the Trump White House.

"The word 'muddle' comes to mind," says Robert McCullough, a respected Portland energy consultant, referring to the justification for the privatization sale included in the Trump budget.

The White House suggests that selling the Bonneville grid would result in lower costs. But that narrative, McCullough wrote in a blistering assessment of the proposal, "displays a severe lack of understanding about the process of setting transmission rates."

McCullough's assessment is an update of a similar analysis he performed when the privatization scheme was first raised by the Trump administration last year. In that analysis issued in June, McCullough said the proposal "raises the question of why these valuable assets would be sold at a discount — and who would get the benefit of the discounted price."

The implications of a sale could be dire for Californians. Bonneville is the majority owner of the California-Oregon Intertie, an electrical transmission system that carries power, including Columbia River-generated hydropower and other clean-energy generation in British Columbia that supports the regional exchange, south to California in the summer and excess California generation to the Pacific Northwest in the winter.

But the idea has drawn fire throughout the region. When it was first broached last year, the Public Power Council, an association of utilities in the Northwest, assailed it as an apparent "transfer of value from the people of the Northwest to the U.S. Treasury," drawing parallels to Manitoba Hydro governance issues elsewhere.

The region's political leaders had especially harsh words for the idea this time around. "Oregonians raised hell last year when Trump tried to raise power bills for Pacific Northwesterners by selling off Bonneville Power, and yet his administration is back at it again," Sen. Ron Wyden (D-Ore.) said after the idea reappeared. "Our investment shouldn't be put up for sale to free up money for runaway military spending or tax cuts for billionaires." Sen. Maria Cantwell (D-Wash.) promised in a statement to work to "stop this bad idea in its tracks."

The notion of privatizing Bonneville predates the Trump administration; it was raised by Bill Clinton and again by George W. Bush, who thought the public would gain if the administration could sell its power at market rates. Both initiatives failed.

The same free-enterprise ideology underlies the Trump proposal. Privatizing the transmission lines "encourages a more efficient allocation of economic resources and mitigates unnecessary risk to taxpayers," the budget asserts. "Ownership of transmission assets is best carried out by the private sector where there are appropriate market and regulatory incentives."

But that's based on a misunderstanding of how transmission rates are set, McCullough says. Transmission is essentially a monopoly enterprise, with rates overseen by the Federal Energy Regulatory Commission based on the grid's costs, and with federal scrutiny of public utilities such as the TVA underscoring that oversight. There's very little in the way of market "incentives" involved in transmission, since no one has come forward to build a competing grid.

Those include the owners' cost of capital — which would be much higher for a private owner than a government agency, McCullough observes, as Hydro One investor uncertainty demonstrates in practice. A private owner, unlike the government-owned Bonneville, also would owe federal income taxes, which would be passed on to consumers.

Then there's the profit motive. Bonneville "currently sells and delivers its power at cost," McCullough wrote last year. "Under a private regime, an investor-owned utility would likely charge a higher rate of return, a pattern seen when UK network profits drew regulatory rebukes."

None of these considerations appears to have been factored into the White House budget proposal. "Either there's an unsophisticated person at the Office of Management and Budget thinking up these numbers himself," McCullough told me, "or there would seem to be ongoing negotiations with an unidentified third party." No such buyer has emerged in the past, however.

What's left is a blind faith in the magic of the market, compounded by ignorance about how the transmission market operates. Put it together, and there's reason to wonder if Trump is even serious about this plan.

Diesel Prices Return to Pre-Ukrainian Conflict Levels

France Diesel Prices at Pre-Ukraine Levels reflect energy market stabilization as supply chains adapt and subsidies help; easing fuel costs, inflation, and logistics burdens for households, transport firms, and the wider economy.

 

Key Points

They mark normalization as oil supply stabilizes, easing fuel costs and logistics expenses for consumers and firms.

✅ Lower transport and logistics operating costs

✅ Softer inflation and improved household budgets

✅ Market stabilization amid adjusted oil supply chains

 

In a significant development for French consumers and businesses alike, diesel prices in France have recently fallen back to levels last seen before the Ukrainian conflict began, mirroring European gas prices returning to pre-war levels across the region. This drop comes as a relief to many who have been grappling with volatile energy costs and their impact on the cost of living and business operations. The return to lower diesel prices is a noteworthy shift in the energy landscape, with implications for the French economy, transportation sector, and broader European market.

Context of Rising Diesel Prices

The onset of the Ukrainian conflict in early 2022 triggered a dramatic increase in global energy prices, including diesel. The conflict's disruption of supply chains, coupled with sanctions on Russian oil and gas exports, contributed to a steep rise in fuel prices across Europe, prompting the EU to weigh emergency electricity price measures to shield consumers. For France, this meant that diesel prices soared to unprecedented levels, putting significant pressure on consumers and businesses that rely heavily on diesel for transportation and logistics.

The impact was felt across various sectors. Transportation companies faced higher operational costs, which were often passed down to consumers in the form of increased prices for goods and services. Additionally, higher fuel costs contributed to broader inflationary pressures, with EU inflation hitting lower-income households hardest, affecting household budgets and overall economic stability.

Recent Price Trends and Market Adjustments

The recent decline in diesel prices in France is a welcome reversal from the peak levels experienced during the height of the conflict. Several factors have contributed to this price reduction. Firstly, there has been a stabilization of global oil markets as geopolitical tensions have somewhat eased and supply chains have adjusted to new realities. The gradual return of Russian oil to global markets, albeit under complex sanctions and trading arrangements, has also played a role in moderating prices.

Moreover, France's strategic reserves and diversified energy sources have helped cushion the impact of global price fluctuations. The French government has also implemented measures to stabilize energy prices, including subsidies and tax adjustments, and a new electricity pricing scheme to satisfy EU concerns, which have helped alleviate some of the financial pressure on consumers.

Implications for the French Economy

The return to pre-conflict diesel price levels brings several positive implications for the French economy. For consumers, the decrease in fuel prices means lower transportation costs, which can ease inflationary pressures and improve disposable income, and, alongside the EDF electricity price deal, reduce overall utility burdens for households. This is particularly beneficial for households with long commutes or those relying on diesel-powered vehicles.

For businesses, especially those in the transportation and logistics sectors, the drop in diesel prices translates into reduced operational costs. This can help lower the cost of goods and services, potentially leading to lower prices for consumers and improved profitability for businesses. In a broader sense, stabilized fuel prices can contribute to overall economic stability and growth, as lower energy costs can support consumer spending and business investment.

Environmental and Policy Considerations

While the decrease in diesel prices is advantageous in the short term, it also raises questions about long-term energy policy and environmental impact, with the recent crisis framed as a wake-up call for Europe to accelerate the shift away from fossil fuels. Diesel, as a fossil fuel, continues to pose environmental challenges, including greenhouse gas emissions and air pollution. The drop in prices might inadvertently discourage investments in cleaner energy alternatives, such as electric and hybrid vehicles, which are crucial for achieving long-term sustainability goals.

In response, there is a growing call for continued investment in renewable energy and energy efficiency measures. France has been actively pursuing policies to reduce its reliance on fossil fuels and increase the adoption of cleaner technologies, amid ongoing EU electricity reform debates with Germany. The government’s support for green energy initiatives and incentives for low-emission vehicles will be essential in balancing short-term benefits with long-term environmental objectives.

Conclusion

The recent return of French diesel prices to pre-Ukrainian conflict levels marks a significant shift in the energy market, offering relief to both consumers and businesses. While this decline brings immediate financial benefits and supports economic stability, it also underscores the ongoing need for a strategic approach to energy policy and environmental sustainability. As France navigates the evolving energy landscape, the focus will need to remain on fostering a transition towards cleaner energy sources while managing the economic and environmental impacts of fuel price fluctuations.

'Unlayering' peak demand could accelerate energy storage adoption

Duration Portfolio Energy Storage aligns layered peak demand with right-sized batteries, enabling peak shaving, gas peaker replacement, and solar-plus-storage synergy while improving grid flexibility, reliability, and T&D deferral through two- to four-hour battery durations.

 

Key Points

An approach that layers battery durations to match peaks, cut costs, replace peakers, and boost grid reliability.

✅ Layers 2- to 4-hour batteries by peak duration

✅ Enables solar-plus-storage and peak shaving

✅ Cuts T&D upgrades, emissions, and fuel costs

 

The debate over energy storage replacing gas-fired peakers has raged for years, but a new approach that shifts the terms of the argument could lead to an acceleration of storage deployments.

Rather than looking at peak demand as a single mountainous peak, some analysts now advocate a layered approach that allows energy storage to better match peak needs and complement ongoing efforts to improve solar and wind power across the grid.

"You don’t have to have batteries that run to infinity."

Some developers of solar-plus-storage projects, bolstered by cheap batteries, say they can already compete head-to-head with gas-fired peakers. "I can beat a gas peaker anywhere in the country today with a solar-plus-storage power plant," Tom Buttgenbach, president and CEO of developer 8minutenergy Renewables, recently told S&P Global.

Customers are very busy these days and rebate programs need to fit the speed of their life. Participation should be quick, easy, and accessible anywhere.

Others disagree. Storage is not disruptive for generation, but will be disruptive for transmission and distribution, Kris Zadlo, executive vice president and chief development officer at Invenergy, told the audience at a Bloomberg New Energy Finance conference last spring. Invenergy, like many renewable power developers, develops generation, energy storage and transmission projects.

But there is another path that avoids the pitfalls of positions on either end of the all-or-none approach. "Do the analysis of the need itself," Ray Hohenstein, market applications director at Fluence, told Utility Dive. If the need is only two hours in duration, it may be best served by a two-hour battery. "You don’t have to have batteries that run to infinity."

 

Storage vs. fossil fuel peakers

Energy storage has several benefits over traditional fossil fuel peaking plants, Hohenstein said. It is instantaneous, it has no emissions and requires no fuel, and has limited infrastructure needs. It can also help the grid absorb higher levels of renewable generation by soaking up excess output, such as solar power at noon, and many planned storage additions will be paired with solar in the next few years. But the one thing energy storage cannot do, he said, is provide limitless energy.

So, instead of looking at replacing an individual peaker, Hohenstein advocated a "duration portfolio" approach that uses energy storage to shave peak load.

If the need is for 150 MW of resources that will never need to run for more than two hours at a time, then a battery is "quite cheap," significantly less than a four or eight-hour battery, said Hohenstein. "If you fill up your peak by duration layer, it could be more cost effective."

 

NREL research driver

Fluence’s approach is informed by research by Paul Denholm and Robert Margolis at the National Renewable Energy Laboratory (NREL), released last spring.

The NREL researchers looked at the California market where they said 11 GW of fossil fuel capacity is expected to be retired by 2029 because of new once-through-cooling requirements that are taking effect. A lot of that capacity is peaking capacity and, according to NREL’s analysis, a large fraction could be replaced with four-hour energy storage, assuming continued storage cost reductions and growth in solar installations.

The key in NREL’s research was the level of solar power penetration. There is a "synergistic" relationship between solar penetration and storage deployment, the researchers wrote, and other studies suggest wind and solar could meet 80% of U.S. demand as these trends continue.

✅ Enhances sustainability and lowers operating costs

 

In a significant step towards sustainable mining practices, Rio Tinto has completed the largest off-grid solar power plant in Canada’s Northwest Territories. This groundbreaking achievement not only highlights the company's commitment to renewable energy, as Canada nears 5 GW of solar capacity nationwide, but also sets a new standard for the mining industry in remote and off-grid locations.

Located in the remote Diavik Diamond Mine, approximately 220 kilometers south of the Arctic Circle, Rio Tinto's off-grid solar power plant represents a technological feat in harnessing renewable energy in challenging environments. The plant is designed to reduce reliance on diesel fuel, traditionally used to power the mine's operations, and mitigate carbon emissions associated with mining activities.

The decision to build the solar power plant aligns with Rio Tinto's broader sustainability goals and commitment to reducing its environmental footprint. By integrating renewable energy sources like solar power, a strategy that renewable developers say leads to better, more resilient projects, the company aims to enhance energy efficiency, lower operational costs, and contribute to global efforts to combat climate change.

The Diavik Diamond Mine, jointly owned by Rio Tinto and Dominion Diamond Mines, operates in a remote region where access to traditional energy infrastructure is limited, and where, despite lagging solar demand in Canada, off-grid solutions are increasingly vital for reliability. Historically, diesel generators have been the primary source of power for the mine's operations, posing logistical challenges and environmental impacts due to fuel transportation and combustion.

Rio Tinto's investment in the off-grid solar power plant addresses these challenges by leveraging abundant sunlight in the Northwest Territories to generate clean electricity directly at the mine site. The solar array, equipped with advanced photovoltaic technology, which mirrors deployments such as Arvato's first solar plant in other sectors, is capable of producing a significant portion of the mine's electricity needs during peak solar hours, reducing reliance on diesel generators and lowering overall carbon emissions.

Moreover, the completion of the largest off-grid solar power plant in Canada's Northwest Territories underscores the feasibility and scalability of renewable energy solutions, from rooftop arrays like Edmonton's largest rooftop solar to off-grid systems in remote and resource-intensive industries like mining. The success of this project serves as a model for other mining companies seeking to enhance sustainability practices and operational resilience in challenging geographical locations.

Beyond environmental benefits, Rio Tinto's initiative is expected to have positive economic and social impacts on the local community. By reducing diesel consumption, the company mitigates air pollution and noise levels associated with mining operations, improving environmental quality and contributing to the well-being of nearby residents and wildlife.

Looking ahead, Rio Tinto's investment in renewable energy at the Diavik Diamond Mine sets a precedent for responsible resource development and sustainable mining practices in Canada, where solar growth in Alberta is accelerating, and globally. As the mining industry continues to evolve, integrating renewable energy solutions like off-grid solar power plants will play a crucial role in achieving long-term environmental sustainability and operational efficiency.

In conclusion, Rio Tinto's completion of the largest off-grid solar power plant in Canada's Northwest Territories marks a significant milestone in the mining industry's transition towards renewable energy. By harnessing solar power to reduce reliance on diesel generators, the company not only improves operational efficiency and environmental stewardship but also adds to momentum from corporate power purchase agreements like RBC's Alberta solar deal, setting a positive example for sustainable development in remote regions. As global demand for responsible mining practices grows, initiatives like Rio Tinto's off-grid solar project demonstrate the potential of renewable energy to drive positive change in resource-intensive industries.
