US Senate stimulus bill opens nuclear loan-guarantee door

Wisconsin Solar and Wind Energy advances as rooftop solar, utility-scale farms, and NREL perovskite solar cells improve efficiency; wind turbines gain via wake modeling, yaw control, and grid-scale battery storage to cut carbon emissions.

Key Points

It is Wisconsin's growth in rooftop and utility-scale solar plus optimized wind turbines to cut carbon emissions.

✅ Perovskite solar cells promise higher efficiency, need longevity

✅ Wake modeling and yaw control optimize wind farm output

✅ Batteries and bids can offset reliance on natural gas

Solar energy in Wisconsin continued to grow in 2019, as more homeowners had rooftop panels installed and big utilities started building multi-panel solar farms.

Wind power is increasing more slowly in the state. However, renewable power developers are again coming forward with proposals for multiple turbines.

Nationally, researchers are working on ways to get even more energy from solar and wind, with the U.S. moving toward 30% electricity from wind and solar in coming years, as states like Wisconsin aim to reduce their carbon emissions over the next few decades.

One reason solar energy is growing in Wisconsin is due to the silicon panels becoming more efficient. But scientists haven't finished trying to improve panel efficiency. The National Renewable Energy Laboratory (NREL) in Golden, Col., is one of the research facilities experimenting with brushing a lab-made solution called perovskite onto a portion of a panel called a solar cell.

In a demonstration video supplied by NREL, senior scientist Maikel van Hest said that, in the lab anyway, the painted cell and its electrical connections called contacts, produce more energy:

"There you go! That's how you paint a perovskite solar cell. And you imagine that ultimately what you could do is you could see a company come in with a truck in front of your house and they would basically paint on the contacts first, dry those, and paint the perovskite over it. That you would have photovoltaic cells on the side of your house, put protective coating on it, and we're done."

Another NREL scientist, David Moore, says the new solar cells could be made faster and help meet what's expected to be a growing global demand for energy. However, Moore says the problem has been lack of stability.

"A solar cell with perovskites will last a couple years. We need to get that to 20-25 years, and that's the big forefront in perovskite research, is getting them to last longer," Moore told members of the Society of Environmental Journalists during a recent tour of NREL.

Another part of improving renewable energy is making wind turbines more productive. At NREL's Insight Center, a large screen showing energy model simulations dominates an otherwise darkened room. Visualization scientist Nicholas Brunhart-Lupo points to a display on the screen that shows how spinning turbines at one edge of a wind farm can cause an airflow called a wake, which curtails the power generation of other turbines.

"So what we find in these simulations is these four turbines back here, since they have this used air, this low-velocity wake being blown to their faces, they're only generating about 20% of the energy they should be generating," he explains.

Brunhart-Lupo says the simulations can help wind farm developers with placement of turbines as well as adjustments to the rotor and blades called the yaw system.

Continued progress with renewables may be vital to any state or national pledges to reduce use of fossil fuels and carbon emissions linked to climate change, including Biden's solar expansion plan as a potential pathway. Some scientists say to limit a rise in global temperature, there must be a big decline in emissions by 2050.

But even utilities that say they support use of more renewables, as why the grid isn't 100% renewable yet makes clear, aren't ready to let go of some energy sources. Jonathan Adelman of Xcel Energy, which serves part of Western Wisconsin, says Xcel is on track to close its last two coal-fired power plants in Minnesota. But he says the company will need more natural gas plants, even though they wouldn't run as often.

"It's not perfect. And it is in conflict with our ultimate goal of being carbon-free," says Adelman. "But if we want to facilitate the transition, we still need resources to help that happen."

Some in the solar industry would like utilities that say they need more natural gas plants to put out competitive bids to see what else might be possible. Solar advocates also note that in some states, energy regulators still favor the utilities.

Meanwhile, solar slowly marches ahead, including here in southeastern Wisconsin, as Germany's solar power boost underscores global momentum.

On the roof of a ranch-style home in River Hills, a work crew from the major solar firm Sunrun recently installed mounting brackets for solar panels.

Sunrun Public Policy Director Amy Heart says she supports research into more efficient renewables. But she says another innovation may have to come in the way regulators think.

"Instead of allowing and thinking about from the perspective of the utility builds the power plant, they replace one plant with another one, they invest in the infrastructure; is really thinking about how can these distributed solutions like rooftop solar, peer-to-peer energy sharing, and especially rooftop solar paired with batteries how can that actually reduce some of what the utility needs?

Large-scale energy storage batteries are already being used in some limited cases. But energy researchers continue to make improvements to them, too, with cheap solar batteries beginning to make widespread adoption more feasible as scientists race to reduce the expected additional harm of climate change.

Eletrobras Privatization Strike sparks a 72-hour CNE walkout by Brazil's electricity workers, opposing asset sell-offs and grid privatization while pledging essential services; unions target President Wilson Ferreira Jr. over energy-sector reforms.

Key Points

A 72-hour CNE walkout by Brazil's electricity workers opposing Eletrobras sell-offs, while keeping essential services.

✅ 72-hour strike led by CNE unions and federations

✅ Targets privatization plans and leadership at Eletrobras

✅ Essential services maintained to avoid consumer impact

Brazil's national electricity workers' collective (CNE) has called for a 72-hour strike to protest the privatization of state-run electric company Eletrobras and its subsidiaries.

The CNE, which gathers the electricity workers' confederation, federations, unions and associations, said the strike is to begin at Monday midnight (0300 GMT) and last through midnight Wednesday, even as some utilities elsewhere have considered asking staff to live on site to maintain operations.

Workers are demanding the ouster of Eletrobras President Wilson Ferreira Jr., who they say is the leading promoter of the privatization move.

Some 24,000 workers are expected to take part in the strike. However, the CNE said it will not affect consumers by ensuring essential services, a pledge echoed by utilities managing costs elsewhere such as Manitoba Hydro's unpaid days off during the pandemic.

Quebec EV transition plan aims for 2 million electric vehicles by 2030 and bans new gas cars by 2035, stressing charging infrastructure, incentives, emissions cuts, and industry impacts, with debate over feasibility and economic risks.

Key Points

A provincial policy targeting 2M EVs by 2030 and a 2035 gas-car sales ban, backed by charging buildout and incentives.

✅ Requires major charging infrastructure and grid upgrades

✅ Balances incentives with economic impacts and industry readiness

✅ Gas stations persist while EV adoption accelerates cautiously

Quebec's ambitious push to dominate the electric vehicle (EV) market, echoing Canada's EV goals in its plan, by setting a target of two million EVs on the road by 2030 and planning to ban the sale of new gas-powered vehicles by 2035 has sparked significant debate among industry experts. While the government's objectives aim to reduce greenhouse gas emissions and promote sustainable transportation, some experts question the feasibility and potential economic impacts of such rapid transitions.

Current Landscape of Gas Stations in Quebec

Contrary to Environment Minister Benoit Charette's assertion that gas stations may become scarce within the next decade, industry experts suggest that the number of gas stations in Quebec is unlikely to decline drastically. Carol Montreuil, Vice President of the Canadian Fuels Association, describes the minister's statement as "wishful thinking," emphasizing that the number of gas stations has remained relatively stable over the past decade. Statistics indicate that in 2023, Quebec residents purchased more gasoline than ever before, and EV shortages and wait times further underscore the continued demand for traditional fuel sources.

Challenges in Accelerating EV Adoption

The government's goal of having two million EVs on Quebec roads by 2030 presents several challenges. Currently, there are approximately 200,000 fully electric cars in the province. Achieving a tenfold increase in less than a decade requires substantial investments in charging infrastructure, consumer incentives, and public education to address concerns such as range anxiety and charging accessibility, especially amid electricity shortage warnings across Quebec and other provinces.

Economic Considerations and Industry Concerns

Industry stakeholders express concerns about the economic implications of rapidly phasing out gas-powered vehicles. Montreuil warns that the industry is already struggling and that attempting to transition too quickly could lead to economic challenges, a view echoed by critics who label the 2035 EV mandate delusional. He suggests that the government may be spending excessive public funds on subsidies for technologies that are still expensive and not yet widely adopted.

Public Sentiment and Adoption Rates

Public sentiment towards EVs is mixed, and experiences in Manitoba suggest the road to targets is not smooth. While some consumers, like Montreal resident Alex Rajabi, have made the switch to electric vehicles and are satisfied with their decision, others remain hesitant due to concerns about vehicle cost, charging infrastructure, and the availability of incentives. Rajabi, who transitioned to an EV nine months ago, notes that while he did not take advantage of the incentive program, he is happy with his decision and suggests that adding charging ports at gas stations could facilitate the transition.

The Need for a Balanced Approach

Experts advocate for a balanced approach that considers the pace of technological advancements, consumer readiness, and economic impacts. While the transition to electric vehicles is essential for environmental sustainability, it is crucial to ensure that the infrastructure, market conditions, and public acceptance are adequately addressed, and to recognize that a share of Canada's electricity still comes from fossil fuels, to make the shift both feasible and beneficial for all stakeholders.

In summary, Quebec's ambitious EV targets reflect a strong commitment to environmental sustainability. However, industry experts caution that achieving these goals requires careful planning, substantial investment, and a realistic assessment of the challenges involved as federal EV sales regulations take shape, in transitioning from traditional vehicles to electric mobility.

Duke Energy Carolinas Solar RFP draws 3.9 GW of utility-scale bids, oversubscribed in DEP and DEC, below avoided cost rates, minimal battery storage, strict PPA terms, and interconnection challenges across North and South Carolina.

Key Points

Utility-scale solar procurement in DEC and DEP, evaluated against avoided cost, with few storage bids and PPA terms.

✅ 3.9 GW bids for 680 MW; DEP most oversubscribed

✅ Most projects 7-80 MWac; few include battery storage

✅ Bids must price below 20-year avoided cost estimate

Last week the independent administrator for Duke’s 680 MW solar solicitation revealed data about the projects which have bid in response to the offer, showing a massive amount of interest in the opportunity.

Overall, 18 individuals submitted bids for projects in Duke Energy Carolinas (DEC) territory and 10 in Duke Energy Progress (DEP), with a total of more than 3.9 GW of proposals – more nearly 6x the available volume. DEP was relatively more over-subscribed, with 1.2 GWac of projects vying for only 80 MW of available capacity.

This is despite a requirement that such projects come in below the estimate of Duke’s avoided cost for the next 20 years, and amid changes in solar compensation that could affect project economics. Individual projects varied in capacity from 7-80 MWac, with most coming within the upper portion of that range.

These bids will be evaluated in the spring of 2019, and as Duke Energy Renewables continues to expand its portfolio, Duke Energy Communications Manager Randy Wheeless says he expects the plants to come online in a year or two.

Lack of storage

Despite recent trends in affordable batteries, of the 78 bids that came in only four included integrated battery storage. Tyler Norris, Cypress Creek Renewables’ market lead for North Carolina, says that this reflects that the methodology used is not properly valuing storage.

“The lack of storage in these bids is a missed opportunity for the state, and it reflects a poorly designed avoided cost rate structure that improperly values storage resources, commercially unreasonable PPA provisions, and unfavorable interconnection treatment toward independent storage,” Norris told pv magazine.

“We’re hopeful that these issues will be addressed in the second RFP tranche and in the current regulatory proceedings on avoided cost and state interconnection standards and grid upgrades across the region.”

Limited volume for North Carolina?

Another curious feature of the bids is that nearly the same volume of solar has been proposed for South Carolina as North Carolina – despite this solicitation being in response to a North Carolina law and ongoing legal disputes such as a church solar case that challenged the state’s monopoly model.

SOO Green Underground Transmission Line proposes an HVDC corridor buried along Canadian Pacific railroad rights-of-way to deliver Iowa wind energy to Chicago, enhance grid interconnection, and reduce landowner disruption from new overhead lines.

Key Points

A proposed HVDC project burying lines along a railroad to move Iowa wind power to Chicago and link two grids.

✅ HVDC link from Mason City, IA, to Plano, IL

✅ Buried in Canadian Pacific railroad right-of-way

✅ Connects MISO and PJM grids for renewable exchange

The company behind a proposed underground transmission line that would carry electricity generated mostly by wind turbines in Iowa to the Chicago area said Monday that the $2.5 billion project could be operational in 2024 if regulators approve it, reflecting federal transmission funding trends seen recently.

Direct Connect Development Co. said it has lined up three major investors to back the project. It plans to bury the transmission line in land that runs along existing Canadian Pacific railroad tracks, hopefully reducing the disruption to landowners. It's not unusual for pipelines or fiber optic lines to be buried along railroad tracks in the land the railroad controls.

CEO Trey Ward said he "believes that the SOO Green project will set the standard regarding how transmission lines are developed and constructed in the U.S."

A similar proposal from a different company for an overhead transmission line was withdrawn in 2016 after landowners raised concerns, even as projects like the Great Northern Transmission Line advanced in the region. That $2 billion Rock Island Clean Line was supposed to run from northwest Iowa into Illinois.

The new proposed line, which was first announced in 2017, would run from Mason City, Iowa, to Plano, Ill., a trend echoed by Canadian hydropower to New York projects. The investors announced Monday were Copenhagen Infrastructure Partners, Jingoli Power and Siemens Financial Services.

The underground line would also connect two different regional power operating grids, as seen with U.S.-Canada cross-border transmission approvals in recent years, which would allow the transfer of renewable energy back and forth between customers and producers in the two regions.

More than 36 percent of Iowa's electricity comes from wind turbines across the state.

Jingoli Power CEO Karl Miller said the line would improve the reliability of regional power operators and benefit utilities and corporate customers in Chicago, even amid debates such as Hydro-Quebec line opposition in the Northeast.
