Wasteful air conditioning adds $200 to summer energy bills, reveals BC Hydro

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.

Hurricane Ida New Orleans Infrastructure faced a split outcome: levees and pumps protected against storm surge, while the power grid collapsed as transmission lines failed, prompting large-scale restoration efforts across Louisiana and Mississippi.

Key Points

It summarizes Ida's impact: levees and pumps held, but the power grid failed, causing outages and slow restoration.

✅ Levees and pumps mitigated flooding and storm surge impacts.

✅ All transmission lines failed, crippling the power grid.

✅ Crews and drones assess damage; restoration may take weeks.

Infrastructure in the city of New Orleans turned in a mixed performance against the fury of Hurricane Ida, with the levees and pumps warding off catastrophic flooding even as the electrical grid, part of the broader Louisiana power grid, failed spectacularly.

Ida’s high winds, measuring 150 miles (240 kilometers) an hour at landfall, took out all eight transmissions lines that deliver power into New Orleans, ripped power poles in half and crumpled at least one steel transmission tower into a twisted metal heap, knocking out electricity to all of the city. A total of more than 1.2 million homes and businesses in Louisiana and Mississippi lost power. While about 90,000 customers were reconnected by Monday afternoon, many could face days without electricity, and frustration can mount as seen during the Houston outage after major storms.

In contrast, the New Orleans area’s elaborate flood defenses seem to have held up, a vindication of the Army Corps of Engineers’ $14.5 billion project to rebuild levees, flood gates and pumps in the wake of the devastation wrought by Hurricane Katrina in 2005. While there were reports of scattered deaths tied to Ida, the city escaped the kind of flooding that destroyed entire neighborhoods in Katrina’s wake, left parts of the city uninhabitable for months and claimed 1,800 lives. 

“The situation in New Orleans, as bad as it is today with the power, could be so much worse,” Louisiana Governor John Bel Edwards said Monday on the Today Show, praising the levee system’s performance. “All you have to do is go back 16 years to get a glimpse of what that would have been like.”

While the levees’ resiliency is no doubt due to the rebuilding effort that followed Katrina, the starkly different outcomes also stems from the storms’ different characteristics. Katrina slammed the coast with a 30-foot storm surge of ocean water, while preliminary estimates from Ida put its surge far lower. 

Ida’s winds, however, were stronger than Katrina’s, and that’s what ultimately took out so many power lines, a dynamic that also saw Texas utilities struggle during Harvey. Deanna Rodriguez, the chief executive officer of power provider Entergy New Orleans, declined to comment on when service would be restored, saying the company was using helicopters and drones to help assess the damage.

Michael Webber, an energy and engineering professor at the University of Texas at Austin, estimated power restoration will take days and possibly weeks, a pattern seen in Florida restoration timelines after major hurricanes, based on the initial damage reports from the storm. More than 25,000 workers from at least 32 states and Washington are mobilized to assist with power restoration efforts, similar to FPL's massive response after Irma, according to the Edison Electric Institute.

“The question is, how long will it take to rebuild these lines,” Webber said. The utilities will first need to complete their damage assessments before they can get a sense of repair timelines, a step that Gulf Power crews have highlighted in past recoveries, he said. “You can imagine that will take days at least, possibly weeks.”

The loss of electricity will have other affects as well, and even though grid resilience during the pandemic was strong, local systems face immediate constraints. Sewer substations, for example, need electricity to keep wastewater moving, said Ghassan Korban, executive director of the New Orleans Sewerage & Water Board. The storm knocked out power to about 80 of the city’s 84 pumping stations, he said at a Monday press conference. “Without electricity, wastewater backs up and can cause overflows,” he said, adding that residents should conserve water to lessen stress on the system.

Canadian electricity transmission enables grid resilience, long-distance power trade, and decarbonization by integrating renewables, hydroelectric storage, and HVDC links, providing backup during extreme weather and lowering costs to reach net-zero, clean energy targets.

Key Points

An interprovincial high-voltage grid that shares clean power to deliver reliable, low-cost decarbonization.

✅ Enables resilience by sharing power across weather zones

✅ Integrates renewables with hydro storage via HVDC links

✅ Lowers decarbonization costs through interprovincial trade

As the recent disaster in Texas showed, climate change requires electricity utilities to prepare for extreme events. This “global weirding” is leaving Canadian electricity grids increasingly exposed to harsh weather that leads to more intense storms, higher wind speeds, heatwaves and droughts that can threaten the performance of electricity systems.

The electricity sector must adapt to this changing climate while also playing a central role in mitigating climate change. Greenhouse gas emissions can be reduced a number of ways, but the electricity sector is expected to play a central role in decarbonization, including powering a net-zero grid by 2050 across Canada. Zero-emissions electricity can be used to electrify transportation, heating and industry and help achieve emissions reduction in these sectors.

Enhancing long-distance transmission is viewed as a cost-effective way to enable a clean and reliable power grid, and to lower the cost of meeting our climate targets. Now is the time to strengthen transmission links in Canada, with concepts like a western Canadian electricity grid gaining traction.

Insurance for climate extremes
An early lesson from the Texas power outages is that extreme conditions can lead to failures across all forms of power supply. The state lost the capacity to generate electricity from natural gas, coal, nuclear and wind simultaneously. But it also lacked cross-border transmission to other electricity systems that could have bolstered supply.

Long-distance transmission offers the opportunity to escape the correlative clutch of extreme weather, by accessing energy and spare capacity in areas not beset by the same weather patterns. For example, while Texas was in its deep freeze, relatively balmy conditions in California meant there was a surplus of electricity generation capability in that region — but no means to get it to Texas. Building new transmission lines and connections across broader regions, including projects like a hydropower line to New York that expand access, can act as an insurance policy, providing a back-up for regions hit by the crippling effects of climate change.

Transmission is also vulnerable to climate disruptions, such as crippling ice storms that leave wires temporarily inoperable. This may mean using stronger poles when building transmission, or burying major high-voltage transmission links, or deploying superconducting cables to reduce losses.

In any event, more transmission links between regions can improve resilience by co-ordinating supply across larger regions. Well-connected grids that are larger than the areas disrupted by weather systems can be more resilient to climate extremes.

Lowering the cost of clean power
Adding more transmission can also play a role in mitigating climate change. Numerous studies have found that building a larger transmission grid allows for greater shares of renewables onto the grid, ultimately lowering the overall cost of electricity.

In a recent study, two of us looked at the role transmission could play in lowering greenhouse gas emissions in Canada’s electricity sector. We found the cost of reducing greenhouse gas emissions is lower when new or enhanced transmission links can be built between provinces.

Much of the value of transmission in these scenarios comes from linking high-quality wind and solar resources with flexible zero-emission generation that can produce electricity on demand. In Canada, our system is dominated by hydroelectricity, but most of this hydro capacity is located in five provinces: British Columbia, Manitoba, Ontario, Québec and Newfoundland and Labrador.

In the west, Alberta and Saskatchewan are great locations for building low-cost wind and solar farms. Enhanced interprovincial transmission would allow Alberta and Saskatchewan to build more variable wind and solar, with the assurance that they could receive backup power from B.C. and Manitoba when the wind isn’t blowing and the sun isn’t shining.

When wind and solar are plentiful, the flow of low cost energy can reverse to allow B.C. and Manitoba the opportunity to better manage their hydro reservoir levels. Provinces can only benefit from trading with each other if we have the infrastructure to make that trade possible.

A recent working paper examined the role that new transmission links could play in decarbonizing the B.C. and Alberta electricity systems. We again found that enabling greater electricity trade between B.C. and Alberta can reduce the cost of deep cuts to greenhouse gas emissions by billions of dollars a year. Although we focused on the value of the Site C project, in the context of B.C.'s clean energy shift, the analysis showed that new transmission would offer benefits of much greater value than a single hydroelectric project.

Getting transmission built
With the benefits that enhanced electricity transmission links can provide, one might think new projects would be a slam dunk. But there are barriers to getting projects built.

First, electricity grids in Canada are managed at the provincial level, most often by Crown corporations. Decisions by the Crowns are influenced not simply by economics, but also by political considerations. If a transmission project enables greater imports of electricity to Saskatchewan from Manitoba, it raises a flag about lost economic development opportunity within Saskatchewan. Successful transmission agreements need to ensure a two-way flow of benefits.

Second, transmission can be expensive. On this front, the Canadian government could open up the purse strings to fund new transmission links between provinces. It has already shown a willingness to do so.

Lastly, transmission lines are long linear projects, not unlike pipelines. Siting transmission lines can be contentious, even when they are delivering zero-emissions electricity. Using infrastructure corridors, such as existing railway right of ways or the proposed Canadian Northern Corridor, could help better facilitate co-operation between regions and reduce the risks of siting transmission lines.

If Canada can address these barriers to transmission, we should find ourselves in an advantageous position, where we are more resilient to climate extremes and have achieved a lower-cost, zero-emissions electricity grid.

Electric mining equipment enables zero-emission, diesel-free operations at Goldcorp's Borden mine, using Sandvik battery-electric drills and LHD trucks to cut ventilation costs, noise, and maintenance while improving underground air quality.

Key Points

Battery-powered mining equipment replaces diesel, cutting emissions and ventilation costs in underground operations.

✅ Cuts diesel use, heat load, and noise in underground headings.

✅ Reduces ventilation infrastructure and operating expense.

✅ Improves air quality, worker health, and equipment uptime.

Mining operations get a lot of flack for creating environmental problems around the world. Yet they provide much of the basic material that keeps the global economy humming. Some mining companies are drilling down in their efforts to clean up their acts, exploring solutions such as recovering mine heat for power to reduce environmental impact.

As the world’s fourth-largest gold mining company Goldcorp has received its share of criticism about the impact it has on the environment.

In 2016, the Canadian company decided to do something about it. It partnered with mining-equipment company Sandvik and began to convert one of its mines into an all-electric operation, a process that is expected to take until 2021.

The efforts to build an all-electric mine began with the Sandvik DD422iE in Goldcorp’s Borden mine in Ontario, Canada.

The machine weighs 60,000 pounds and runs non-stop on a giant cord. It has a 75-kwh sodium nickel chloride battery to buffer power demands, a crucial consideration as power-hungry Bitcoin facilities can trigger curtailments during heat waves, and to move the drill from one part of the mine to another.

This electric rock-chewing machine removes the need for the immense ventilation systems needed to clean the emissions that diesel engines normally spew beneath the surface in a conventional mining operation, though the overall footprint depends on electricity sources, as regions with Clean B.C. power imports illustrate in practice.

These electric devices improve air quality, dramatically reduce noise pollution, and remove costly maintenance of internal combustion engines, Goldcorp says.

More importantly, when these electric boring machines are used across the board, it will eliminate the negative health effects those diesel drills have on miners.

“It would be a challenge to go back,” says big drill operator Adam Ladouceur.

Mining with electric equipment also removes second- or third-highest expenditure in mining, the diesel fuel used to power the drills, said Goldcorp spokesman Pierre Noel, even as industries pursue dedicated energy deals like Bitcoin mining in Medicine Hat to manage power costs. (The biggest expense is the cost of labor.)

Aside from initial cost, the electric Borden mine will save approximately $7 million ($9 million Canadian) annually just on diesel, propane and electricity.

Along with various sizes of electric drills and excavating tools, Goldcorp has started using electric powered LHD (load, haul, dump) trucks to crush and remove the ore it extracts, and Sandvik is working to increase the charging speed for battery packs in the 40-ton electric trucks which transport the ore out of the mines, while utilities add capacity with new BC generating stations coming online.

The agreement will enable the two sides to initiate technical and financial feasibility studies for the project, which aims to enhance the stability and reliability of electricity networks in both countries, aligning with measures to secure power such as Ireland's electricity supply plan pursued internationally.

The initial feasibility studies, which came as part of the comprehensive Arab electricity linkage issued by the Arab League in 2014, had shown the possibility of implementing the Jordanian-Saudi linkage, as electricity markets evolve in places like Alberta electricity market changes toward new designs.

Regional developments, including a Lebanon electricity goodwill gesture that sowed discord, underscore the complexities of power-sector reform.

Also on Wednesday, the Government approved the third amendment to the grant agreement provided by the EU for a programme of financial inclusion through improving the governance and the spread of micro-financing in Jordan.

Jordan and the EU signed the grant agreement on December 14, 2014 to support the general budget.

The Cabinet also approved the recommendations of the ministerial team tasked with overseeing the annual and financial plans of public credit funds in the Kingdom.

The recommendations included establishing a guidance office to introduce the governmental lending programmes and windows within Iradah centres affiliated with the Planning and International Cooperation Ministry.

The Council of Ministers decided to oblige the government institutions to execute all of their correspondences to the Jordan Customs Department (JCD) electronically.

The decision also includes cancelling the provision of 55 JCD services by conventional paper works and to be provided only online.

The council also approved the outcomes of the study to restructure the governmental body.

The outcomes proposed activating the Higher Health Council, cancelling the independence of the Vocational and Technical Employment Training Fund transferring its functions to the Employment and Development Fund, and activating the National ICT Centre.

The government has cancelled the National Fund to Support Sports and the Scientific Support Fund.

Connect the Grid Act links ERCOT to neighboring grids via high-voltage interconnections, enhancing reliability, resilience, and renewables integration. It enables power imports and exports with SPP, MISO, and the Western Interconnection under FERC oversight.

Key Points

A plan to link ERCOT with neighboring grids, improving reliability, enabling energy trade, and integrating renewables.

✅ High-voltage ties with SPP, MISO, and the Western Interconnection

✅ Enables imports during crises and exports of surplus power

✅ Brings ERCOT under FERC oversight; DoE to study Mexico links

In the aftermath of the devastating 2021 Texas blackouts, which exposed the vulnerabilities of the state's energy infrastructure, a significant legislative effort is underway to transform Texas from an energy island into a connected component of the broader U.S. power grid. Spearheaded by U.S. Representative Greg Casar, D-Austin, the proposed Connect the Grid Act is part of a push for smarter electricity infrastructure that seeks to remedy the isolation of the Electric Reliability Council of Texas (ERCOT) from neighboring power grids, a condition that significantly contributed to the crisis during Winter Storm Uri.

The blackouts, which left millions without power and resulted in significant loss of life and economic damage, underscored the inherent risks of Texas's unique energy infrastructure. Unlike the rest of the continental U.S., Texas's grid operates independently, limiting its ability to import electricity during emergencies. This isolation was a critical factor in the state's inability to respond effectively to the increased demand for power during the storm.

Recognizing the urgent need for a more resilient and integrated energy system, Rep. Casar's legislation aims to establish high-voltage connections between ERCOT and adjacent grid-operating organizations, including the Southern Power Pool, MISO, and the Western Interconnection. This would not only improve the reliability of Texas's power supply by enabling energy imports during crises but also allow the state to export surplus energy, thereby enhancing the economic efficiency and sustainability of its energy market.

The Connect the Grid Act proposes a range for the new connections' transfer capabilities, aiming to significantly boost the amount of power that can be shared between Texas and its neighbors. Such interconnectivity is anticipated to reduce energy costs for consumers by mitigating scarcity and enabling access to Texas's vast renewable energy resources, even as grid modernization affordability remains a point of debate among stakeholders. However, the bill faces opposition due to concerns over federal oversight, as it would bring ERCOT under the jurisdiction of the Federal Energy Regulatory Commission (FERC).

Some analysts note that policies such as later school start dates can ease late-summer peak demand as well.

At a press conference held at the IBEW Local 520 headquarters, Rep. Casar, along with environmental groups, labor unions, and frontline workers, highlighted the benefits of the proposed legislation. The bill also includes provisions for a Department of Energy study on the potential benefits of interconnecting with Mexico, and parallels proposals for macrogrids in Canada that seek greater reliability across borders.

The Connect the Grid Act reflects a broader national trend towards increasing the interconnectivity of regional power grids, a move deemed essential for the transition to renewable energy and combating climate change risks to the U.S. grid through expanded interconnection. By enabling the flow of clean energy from renewable-rich areas like Texas to energy-hungry urban centers, the legislation supports a more sustainable and resilient national energy infrastructure.

Critics of Texas's grid independence, including energy experts and federal regulators, have long advocated for such interconnections. They argue that increased access to neighboring grids could have mitigated the effects of the 2021 blackouts and emphasize the importance of a grid that can withstand extreme weather events. The Federal Energy Regulatory Commission and the North American Electric Reliability Corp. have both explored mandates and studies to promote electricity transfer between regional grids, while states like California grid upgrades are investing to modernize networks as well, highlighting the national importance of grid interconnectivity.

Despite the potential challenges of increased federal regulation, proponents of the Connect the Grid Act argue that the benefits of interconnection far outweigh the drawbacks. By reducing energy costs, enhancing grid reliability, and promoting renewable energy, the legislation aims to secure a more sustainable and equitable energy future for Texas and the nation.

If passed, the Connect the Grid Act would mark a historic shift in Texas's energy policy, ending the state's long-standing isolation and positioning it as a key player in the national and potentially international energy landscape, and echoes calls for a western Canadian electricity grid to strengthen regional ties. The bill sets a completion deadline of January 1, 2035, for the construction of the new connections, with other projects, like the one by Pattern Energy, potentially connecting ERCOT to parts of the Southeastern grid even earlier, by 2029. This legislative effort represents a critical step towards ensuring that Texas can meet its energy needs reliably and sustainably, while also contributing to the broader goal of transitioning to a cleaner, more resilient power system.
