A demonstration project along the Missouri River might be one result of a study on the possibility of integrating hydroelectric power and wind-generated power, according to Sen. John Thune.

The study by the Western Area Power Administration is expected to be released soon.

The idea comes from a wind-hydro project that was conducted on the Columbia River in Washington, where Thune said managers have successfully integrated the use of river dams and wind turbines. When the wind is strong, less hydropower is used; when the wind is weak, more hydropower is employed.

"When we learned about that, we thought it made a lot of sense for South Dakota because of our mainstem dams, and the fact that 56 percent of our energy in South Dakota is generated from that hydro source," said Thune, R-S.D. "Earlier this week, I discussed that study with WAPA and they informed me that the Missouri River is a potential location for coordination and they recommended we demonstrate a project along the Missouri."

WAPA is an agency within the U.S. Department of Energy that sells electricity to cities, tribes and various agencies. When it cannot meet demand through its traditional power sources, such as the dams along the Missouri River, it is forced to purchase power elsewhere.

Thune said WAPA has been urged to conduct such a study on the Missouri River, but the process was bogged down because "it became much more complicated than they anticipated."

Along with figuring, on an hour-by-hour basis, wind potential in the state, there is the always present issue of energy transmission, Thune said. Transmission has been an ongoing roadblock to wind energy projects in South Dakota.

"I think WAPAs concern has to do with the excess capacity that would be required to transmit energy generated by wind," Thune said. "And since they're the only show in town in some parts of South Dakota that has transmission, it's always a question of if they will have to pass on additional costs to their rate payers to open up their lines."

The senator said he hopes the release of the study shows that WAPA understands the possibilities that exist with wind power in South Dakota.

"I think the time when (a wind-hydro integration) will really work is in times when you have particularly low hydro generation," he said. "When they're not generating (power) on the dam, they have to buy it someplace else and they buy it at a premium. If you can complement hydro and wind, you hopefully can figure out how to drive prices down."

Roads Need More Electricity: They Will Make It Themselves

Electrically Smart Roads integrate solar road surfaces, inductive charging, IoT sensors, AI analytics, and V2X to power lighting, deicing, and monitoring, reducing grid dependence while enabling dynamic EV charging and real-time traffic management.

 

Key Points

Electrically smart roads generate power, sense conditions, and charge EVs using solar, IoT, AI, and dynamic infrastructure.

✅ Solar surfaces, verges, and gantries generate on-site electricity

✅ Inductive lanes enable dynamic EV charging at highway speeds

✅ Embedded IoT sensors and AI deliver real-time traffic insights

 

As more and more capabilities are added to roads instead of simply covering a country with extra roads, they are starting to make their own electricity, notably as solar road surface but then with added silent wind turbines, photovoltaic verges and barriers and more.

That toll gate, street light and traffic monitoring system all need electricity. Later, roads that deice and charge vehicles at speed will need huge amounts of electricity. For now, electricity for road systems is provided by very expensive infrastructure to the grid, and grid flexibility for EVs remains a concern, except for a few solar/ wind street lights in China and Korea for example. However, as more and more capabilities are added to roads instead of simply covering a country with extra roads, they are starting to make their own electricity, notably as solar road surface but then with added silent wind turbines, photovoltaic verges and barriers and more. There is also highly speculative work in the USA and UK on garnering power from road surface movement using piezoelectrics and electrodynamics and even its heat.

China plans to create an intelligent transport system by 2030. The country hopes to build smart roads that will not only be able to charge electric cars as they drive but also monitor temperature, traffic flow and weight load using artificial intelligence. Indeed, like France, the Netherlands and the USA, where U.S. EV charging capacity is under scrutiny, it already has trials of extended lengths of solar road which cost no more than regular roads. In an alternative approach, vehicles go under tunnels of solar panels that also support lighting, light-emitting signage and monitoring equipment using the electricity made where it is needed. See the IDTechEx Research report, Electrically Smart Roads 2018-2028 for more.

Raghu Das, CEO of IDTechEx says, "The spiral vertical axis wind turbines VAWT in Asia rarely rotate because they are too low but much higher versions are planned on large UK roadside vehicle charging centres that should work well. H shaped VAWT is also gaining traction - much slower and quieter than the propeller shape which vibrates and keeps you awake at night in an urban area.

The price gap between the ubiquitous polycrystalline silicon solar cell and the much more efficient single crystal silicon is narrowing. That means that road furniture such as bus shelters and smart gantries will likely go for more solar rather than adding wind power in many cases, a shift mirrored by connected solar tech in homes, because wind power needs a lot of maintenance and its price is not dropping as rapidly."

The IDTechEx Research report, Off Grid Electric Vehicle Charging: Zero Emission 2018-2028 analyses that aspect, while vehicle-to-grid strategies may complement grid resources. The prototype of a smart road is already in place on an expressway outside of Jinan, providing better traffic updates as well as more accurate mapping. Verizon's IoT division has launched a project around intelligent asphalt, which it thinks has the potential to significantly reduce fossil fuel emissions and save time by reducing up to 44% of traffic backups. It has partnered with Sacramento, California, to test this theory.

"By embedding sensors into the pavement as well as installing cameras on traffic lights, we will be able to study and analyze the flow of traffic. Then, we will take all of that data and use it to optimize the timing of lights so that traffic flows easier and travel times are shorter," explains Sean Harrington, vice president of Verizon Smart Communities.

Colorado's Department of Transportation has recently announced its intention to be the first state to pilot smart roads by striking a five-year deal with a smart road company to test the technology. Like planned auto-deicing roads elsewhere, the aim of this project is, first and foremost, to save lives. The technology will detect when a car suddenly leaves a road and send emergency assistance to the area. The IDTechEx Research report Electrically Smart Roads 2018-2028 describes how others work on real time structural monitoring of roads and embedded interactive lighting and road surface signage.

"Smart pavement can make that determination and send that information directly into a vehicle," Peter Kozinski, director of CDOT's RoadX division, tells the Denver Post. "Data is the new asphalt of transportation."   Sensors, processors and other technology are embedded in the Colorado road to extend capability beyond accidents and reach into better road maintenance. Fast adoption relies on the ability to rapidly install sensor-laden pavement or lay concrete slabs. Attention therefore turns to fast adaptation of existing roads. Indeed, even for the heavy coil arrays used for dynamic vehicle charging, even as state power grids face new challenges, in Israel there are machines that can retrofit into the road surface at a remarkable two kilometres of cut and insert in a day.

"It's hard to imagine that these things are inexpensive, with all the electronics in them," Charles Schwartz, a professor of civil and environmental engineering at the University of Maryland, tells the Denver Post concerning the vehicle sensing project, "but CDOT is a fairly sophisticated agency, and this is an interesting pilot project. We can learn a lot, even if the test is only partially successful."

Two-thirds of the U.S. is at risk of power outages this summer

Home Energy Independence reduces electricity costs and outage risks with solar panels, EV charging, battery storage, net metering, and smart inverters, helping homeowners offset tiered rates and improve grid resilience and reliability.

 

Key Points

Home Energy Independence pairs solar, batteries, and smart EV charging to lower bills and keep power on during outages.

✅ Offset rising electricity rates via solar and net metering

✅ Add battery storage for backup power and peak shaving

✅ Optimize EV charging to avoid tiered rate penalties

 

The Department of Energy recently warned that two-thirds of the U.S. is at risk of losing power this summer. It’s an increasingly common refrain: Homeowners want to be less reliant on the aging power grid and don’t want to be at the mercy of electric utilities due to rising energy costs and dwindling faith in the power grid’s reliability.

And it makes sense. While the inflated price of eggs and butter made headlines earlier this year, electricity prices quietly increased at twice the rate of overall inflation in 2022, even as studies indicate renewables aren’t making power more expensive overall, and homeowners have taken notice. In fact, according to Aurora Solar’s Industry Snapshot, 62% expect energy prices will continue to rise.

Homeowners aren’t just frustrated that electricity is pricey when they need it, they’re also worried it won’t be available at all when they feel the most vulnerable. Nearly half (48%) of homeowners are concerned about power outages stemming from weather events, or grid imbalances from excess solar in some regions, followed closely by outages due to cyberattacks on the power grid.

These concerns around reliability and cost are creating a deep lack of confidence in the power grid. Yet, despite these growing concerns, homeowners are increasingly using electricity to displace other fuel sources.

The electrification of everything
From electric heat pumps to electric stoves and clothes dryers, homeowners are accelerating the electrification of their homes. Perhaps the most exciting example is electric vehicle (EV) adoption and the need for home charging. With major vehicle makers committing to ambitious electric vehicle targets and even going all-electric in the future, EVs are primed to make an even bigger splash in the years to come.

The by-product of this electrification movement is, of course, higher electric bills because of increased consumption. Homeowners also risk paying more for every unit of energy they use if they’re part of a tiered pricing utility structure, where energy-insecure households often pay 27% more on electricity because customers are charged different rates based on the total amount of energy they use. Many new electric vehicle owners don’t realize this until they are deep into purchasing their new vehicle, or even when they open that first electric bill after the car is in their driveway.

Sure, this electrification movement can feel counterintuitive given the power grid concerns. But it’s actually the first step toward energy independence, and emerging models like peer-to-peer energy sharing could amplify that over time.

Balancing conflicting movements
The fact is that electrification is moving forward quickly, even among homeowners who are concerned about electricity prices and power grid reliability, and about why the grid isn’t yet 100% renewable in the U.S. This has the potential to lead to even more discontent with electric utilities and growing anxiety over access to electricity in extreme situations. There is a third trend, though, that can help reconcile these two conflicting movements: the growth of solar.

The popularity of solar is likely higher than you think: Nearly 77% of homeowners either have solar panels on their homes or are interested in purchasing solar. The Aurora Solar Industry Snapshot report also showed a nearly 40% year-over-year increase in residential solar projects across the U.S. in 2022, as the country moves toward 30% power from wind and solar overall, aligning with the Solar Energy Industries Association’s (SEIA) Solar Market Insight Report, which found, “Residential solar had a record year [in 2022] with nearly 6 GWdc of installations, representing 40% growth over 2021.”

It makes sense that finding ways to tamp down—even eliminate—growing bills caused by the electrification of homes is accelerating interest in solar, as more households weigh whether residential solar is worth it for their budgets, and residential solar installers are seeing this firsthand. The link between EVs and solar is a great proof point: Almost 80% of solar professionals said EV adoption often drives new interest in solar.

Metering Pilot projects may be good example for Ontario utilities

Ontario Electricity Pricing Pilot Projects explore alternative rates beyond time-of-use, with LDCs and the Ontario Energy Board testing dynamic pricing, demand management, smart-meter billing, and residential customer choice to enhance service and energy efficiency.

 

Key Points

Ontario LDC trials testing alternatives to time-of-use rates to improve billing, demand response, and efficiency.

✅ Data shared across LDCs and Ontario Energy Board provincewide

✅ Tests dynamic pricing, peak/off-peak plans, demand management

✅ Insights to enhance customer choice, bills, and energy savings

 

The results from three electricity pilot projects being offered in southern Ontario will be valuable to utility companies across the province.

Ontario Energy Minister Glenn Thibeault was in Barrie on Tuesday to announce the pilot projects, which will explore alternative pricing plans for electricity customers from three different utility companies, informed by the electricity cost allocation framework guiding rate design.

"Everyone in the industry is watching to see how the pilots deliver.", said Wendy Watson, director of communications for Greater Sudbury Utilities.

"The data will be shared will all the LDCs [local distribution companies] in the province, and probably beyond...because the industry tends to share that kind of information."

Most electricity customers in the province are billed using time-of-use rates, including options like the ultra-low overnight rates that lower costs during off-peak periods, where the cost of electricity varies depending on demand.

The Ontario Energy Board said in a media release that the projects will give residential customers more choice in how much they pay for electricity at different times, reflecting changes for Ontario electricity consumers that expand plan options.

Pilot projects can help improve service

Watson says these kinds of projects give LDCs the chance to experiment and explore new ways of delivering their service, including demand-response initiatives like the Peak Perks program that encourage conservation.

"Any pilot project is a great way to see if in practice if the theory proves out, so I think it's great that the province is supporting these LDCs," she says.

GSU recently completed its own pilot project, the Home Energy Assessment and Retrofit (HEAR) program, which focused on customers who use electric baseboards to heat their homes, amid broader provincial support for electric bills to ease costs."We installed some measures, like programmable thermostats and a few other pieces of equipment into their house," Watson says. "We also made some recommendations about other things that they could do to make their homes more energy efficient."

At the end of the program, GSU provided customers with a report so that they could the see the overall impact on their energy consumption.

Watson says a report on the results of the HEAR program will be released in the near future, for other LDCs interested in new ways to improve their service.

"We think it's incumbent on every LDC...to see what ideas that they can come up with and get approved so they can best serve their customers."

Nord Stream: Norway and Denmark tighten energy infrastructure security after gas pipeline 'attack'

Nord Stream Pipeline Sabotage triggers Baltic Sea gas leaks as Norway and Denmark tighten energy infrastructure security, offshore surveillance, and exclusion zones, after drone sightings near platforms and explosions reported by experts.

 

Key Points

An alleged attack causing Baltic gas leaks and heightened energy security measures in Norway and Denmark.

✅ Norway boosts offshore and onshore site security

✅ Denmark enforces 5 nm exclusion zone near leaks

✅ Drones spotted; police probe sabotage and safety breaches

 

Norway and Denmark will increase security and surveillance around their energy infrastructure sites after the alleged sabotage of Russia's Nord Stream gas pipeline in the Baltic Sea, as the EU pursues a plan to dump Russian energy to safeguard supplies. 

Major leaks struck two underwater natural gas pipelines running from Russia to Germany, which has moved to a 200 billion-euro energy shield amid surging prices, with experts reporting that explosions rattled the Baltic Sea beforehand.

Norway -- an oil-rich nation and Europe's biggest supplier of gas -- will strengthen security at its land and offshore installations, even as it weighs curbing electricity exports to avoid shortages, the country's energy minister said.

The Scandinavian country's Petroleum Safety Authority also urged vigilance on Monday after unidentified drones were seen flying near Norway's offshore oil and gas platforms.

"The PSA has received a number of warnings/notifications from operator companies on the Norwegian Continental Shelf concerning the observation of unidentified drones/aircraft close to offshore facilities" the agency said in a statement.

"Cases where drones have infringed the safety zone around facilities are now being investigated by the Norwegian police."

Meanwhile Denmark will increase security across its energy sector after the Nord Stream incident, as wider market strains, including Germany's struggling local utilities, ripple across Europe, a spokesperson for gas transmission operator Energinet told Upstream.

The Danish Maritime Agency has also imposed an exclusion zone for five nautical miles around the leaks, warning ships of a danger they could lose buoyancy, and stating there is a risk of the escaping gas igniting "above the water and in the air," even as Europe weighs emergency electricity measures to limit prices.

Denmark's defence minister said there was no cause for security concerns in the Baltic Sea region.

"Russia has a significant military presence in the Baltic Sea region and we expect them to continue their sabre-rattling," Morten Bodskov said in a statement.

Video taken by a Danish military plane on Tuesday afternoon showed the extent of one of gas pipeline leaks, with the surface of the Baltic bubbling up as gas escapes, highlighting Europe's energy crisis for global audiences:

Meanwhile police in Sweden have opened a criminal investigation into "gross sabotage" of the Nord Stream 1 and Nord Stream 2 pipelines, and Sweden's crisis management unit was activated to monitor the situation. The unit brings together representatives from different government agencies. 

Swedish Foreign Minister Ann Linde had a call with her Danish counterpart Jeppe Kofod on Tuesday evening, and the pair also spoke with Norwegian Foreign Minister Anniken Huitfeldt on Wednesday, as the bloc debates gas price cap strategies to address the crisis, with Kofod saying there should be a "clear and unambiguous EU statement about the explosions in the Baltic Sea." 

"Focus now on uncovering exactly what has happened - and why. Any sabotage against European energy infrastructure will be met with a robust and coordinated response," said Kofod.

Hydropower Plants to Support Solar and Wind Energy

Solar-Wind-Water West Africa integrates hydropower with solar and wind to boost grid flexibility, clean electricity, and decarbonization, leveraging the West African Power Pool and climate data modeling reported in Nature Sustainability.

 

Key Points

A strategy using hydropower to balance solar and wind, enabling reliable, low-carbon electricity across West Africa.

✅ Hydropower dispatch covers solar and wind shortfalls.

✅ Regional interconnection via West African Power Pool.

✅ Cuts CO2 versus gas while limiting new dam projects.

 

Hydropower plants can support solar and wind power, rather unpredictable by nature, in a climate-friendly manner. A new study in the scientific journal Nature Sustainability has now mapped the potential for such "solar-wind-water" strategies for West Africa: an important region where the power sector is still under development, amid IEA investment needs for universal access, and where generation capacity and power grids will be greatly expanded in the coming years. "Countries in West Africa therefore now have the opportunity to plan this expansion according to strategies that rely on modern, climate-friendly energy generation," says Sebastian Sterl, energy and climate scientist at Vrije Universiteit Brussel and KU Leuven and lead author of the study. "A completely different situation from Europe, where power supply has been dependent on polluting power plants for many decades - which many countries now want to rid themselves of."

Solar and wind power generation is increasing worldwide and becoming cheaper and cheaper. This helps to keep climate targets in sight, but also poses challenges. For instance, critics often argue that these energy sources are too unpredictable and variable to be part of a reliable electricity mix on a large scale, though combining multiple resources can enhance project performance.

"Indeed, our electricity systems will have to become much more flexible if we are to feed large amounts of solar and wind power into the grid. Flexibility is currently mostly provided by gas power plants. Unfortunately, these cause a lot of CO2 emissions," says Sebastian Sterl, energy and climate expert at Vrije Universiteit Brussel (VUB) and KU Leuven. "But in many countries, hydropower plants can be a fossil fuel-free alternative to support solar and wind energy. After all, hydropower plants can be dispatched at times when insufficient solar and wind power is available."

The research team, composed of experts from VUB, KU Leuven, the International Renewable Energy Agency (IRENA), and Climate Analytics, designed a new computer model for their study, running on detailed water, weather and climate data. They used this model to investigate how renewable power sources in West Africa could be exploited as effectively as possible for a reliable power supply, even without large-scale storage, in line with World Bank support for wind in developing countries. All this without losing sight of the environmental impact of large hydropower plants.

"This is far from trivial to calculate," says Prof. Wim Thiery, climate scientist at the VUB, who was also involved in the study. "Hydroelectric power stations in West Africa depend on the monsoon; in the dry season they run on their reserves. Both sun and wind, as well as power requirements, have their own typical hourly, daily and seasonal patterns. Solar, wind and hydropower all vary from year to year and may be impacted by climate change, including projections that wind resources shift southward in coming years. In addition, their potential is spatially very unevenly distributed."

West African Power Pool

The study demonstrates that it will be particularly important to create a "West African Power Pool", a regional interconnection of national power grids to serve as a path to universal electricity access across the region. Countries with a tropical climate, such as Ghana and the Ivory Coast, typically have a lot of potential for hydropower and quite high solar radiation, but hardly any wind. The drier and more desert-like countries, such as Senegal and Niger, hardly have any opportunities for hydropower, but receive more sunlight and more wind. The potential for reliable, clean power generation based on solar and wind power, supported by flexibly dispatched hydropower, increases by more than 30% when countries can share their potential regionally, the researchers discovered.

All measures taken together would allow roughly 60% of the current electricity demand in West Africa to be met with complementary renewable sources, despite concerns about slow greening of Africa's electricity, of which roughly half would be solar and wind power and the other half hydropower - without the need for large-scale battery or other storage plants. According to the study, within a few years, the cost of solar and wind power generation in West Africa is also expected to drop to such an extent that the proposed solar-wind-water strategies will provide cheaper electricity than gas-fired power plants, which currently still account for more than half of all electricity supply in West Africa.

Better ecological footprint

Hydropower plants can have a considerable negative impact on local ecology. In many developing countries, piles of controversial plans for new hydropower plants have been proposed. The study can help to make future investments in hydropower more sustainable. "By using existing and planned hydropower plants as optimally as possible to massively support solar and wind energy, one can at the same time make certain new dams superfluous," says Sterl. "This way two birds can be caught with one stone. Simultaneously, one avoids CO2 emissions from gas-fired power stations and the environmental impact of hydropower overexploitation."

Global relevance

The methods developed for the study are easily transferable to other regions, and the research has worldwide relevance, as shown by a US 80% study on high variable renewable shares. Sterl: "Nearly all regions with a lot of hydropower, or hydropower potential, could use it to compensate shortfalls in solar and wind power." Various European countries, with Norway at the front, have shown increased interest in recent years to deploy their hydropower to support solar and wind power in EU countries. Exporting Norwegian hydropower during times when other countries undergo solar and wind power shortfalls, the European energy transition can be advanced.

Manitoba Hydro scales back rate increase next year

Manitoba Hydro 3.5 Percent Rate Increase proposes a smaller electricity rate hike under Public Utilities Board oversight to bolster financial reserves, address debt and Bipole III costs, amid shifting export sales and water flow conditions.

 

Key Points

It is Manitoba Hydro's proposed 3.5% electricity rate hike for 2019-20 to shore up finances under PUB oversight.

✅ PUB review sought without lengthy hearing

✅ Revenue boost forecast at 59 million dollars

✅ Natural gas rates flat; class shifts adjust bills

 

Manitoba Hydro is scaling back its rate hike request for next year, instead of the annual 7.9 per cent hikes the Crown corporation previously said it would need until 2023-24 to address debt. 

Hydro is asking the Public Utilities Board for a 3.5 per cent rate increase next year, which would take effect on April 1.

In last week's application, Hydro said its new board is reviewing the corporation's financial picture. Once that is complete, the utility expects to submit a new multi-year rate plan in late 2019 that addresses the organization's long-term future.

"It's too speculative at this point to discuss any possible future rate increases," spokesperson Bruce Owen said in an email.

The proposed increase next year is similar to other jurisdictions and nearly in line with the Public Utilities Board's decision to allow an average 3.6 per cent jump in electricity rates in 2018-19, which began this summer.

"The requested 3.5 per cent rate increase … generates a modest level of net income under average water flow conditions that will assist in gradually building the revenue base and reduce the risk of the corporation incurring a loss" in 2019-20, the rate application said.

If approved, consumers would face their second rate increase from Hydro in under a year.

Crown Services Minister Colleen Mayer said she's sympathetic to customers bracing for another rate increase amid NL rate hike concerns that far exceeds the rate of inflation.

"I hear that, very clearly," she said. "The NDP left us with an insurmountable problem — we're trying to fix that."

Hydro goes to court over special rate class for First Nations residents in Manitoba

National Energy Board OK's Manitoba-Minnesota Transmission Project

Next year's rate increase is projected to bring in $59 million of revenue, boosting the Crown corporation's financial reserves by $31 million.

Without it, the utility would deal with a net loss, it said.

This time, Hydro officials are asking PUB to forgo a rate hearing, suggesting neither itself nor the board has the resources for a lengthy six- to nine-month process to review an application where not much has changed financially and would generate a "minimum level of net income," Hydro said in a letter to the board.

The short-term rate relief, the letter recommends, should be "awarded in a timely and cost-effective manner, recognizing that the corporation's long-term financial forecasts will be finalized and available for review" in late 2019.

Hydro's net income next year will be lower than projected, the rate application said, due to a reduction in export sales and increases in depreciation and financing costs from Bipole III.

"Even though they had a total implosion of their previous board, on this very issue, they haven't learned lessons and they continue to be cheerleaders for these rapid rate increases," Kinew said, referring to the exodus of every board member but one earlier this year.

Manitoba Hydro's burgeoning debt surpasses $19 billion

On natural gas, Manitoba Hydro is asking PUB for no rate increase for the next two years.

There will, however, be some changes in rates in different customer classes, Owen said, resulting in modest rate reductions for mainly residential customers and increases for customers who use a lot of natural gas.

The corporation also wants to stop collecting fees to support the furnace replacement program. The initiative will continue with existing fees.
