A “sweet” burning odor emitted from the Ames Power Plant is non-toxic and the result of firing up a second generating unit to meet high electric demand.

Electric Services Director Donald Kom confirmed the odor as coming from cooling towers at the plant. Employees noticed the smell and immediately started investigating, he said.

A water treatment chemical consultant determined the odor was caused by a sequence of events in firing up the second generating unit. The first steps are to fill the cooling towers with well water and treat the water with a small quantity of bleach.

“While this process always creates a sweet, burnt odor, the smell was likely more noticeable this week due to the hot, humid weather,” said Susan Gwiasda, the city’s public relations officer.

The consultant determined the odor was not hazardous to people or plants, she said.

Kom said the electric service is modifying its start-up procedures to minimize the smell due to neighborhood concerns.

Solar changing shape of electricity prices in Northern Europe

EU Solar Impact on Electricity Prices highlights how rising solar PV penetration drives negative pricing, shifts peak hours, pressures wholesale markets, and challenges grid balancing, interconnection, and flexibility amid changing demand and renewables growth.

 

Key Points

Explains how rising solar PV cuts wholesale prices, shifts negative-price hours, and strains grid flexibility.

✅ Negative pricing events surge with higher solar penetration.

✅ Afternoon price dips replace night-time wind-led lows.

✅ Grid balancing, interconnectors, and flexibility become critical.

 

The latest EU electricity market report has confirmed the affect deeper penetration of solar is having on wholesale electricity prices more broadly.

The Quarterly Report on European Electricity Markets for the final three months of last year noted the number of periods of negative electricity pricing doubled from 2019, to almost 1,600 such events, as global renewables set new records in deployment across markets.

Having experienced just three negative price events in 2019, the Netherlands recorded almost 100 last year “amid a dramatic increase in solar PV capacity,” in the nation, according to the report.

Whilst stressing the exceptional nature of the Covid-19 pandemic on power consumption patterns, the quarterly update also noted a shift in the hours during which negative electric pricing occurred in renewables poster child Germany. Previously such events were most common at night, during periods of high wind speed and low demand, but 2020 saw a switch to afternoon negative pricing. “Thus,” stated the report, “solar PV became the main driver behind prices falling into negative territory in the German market in 2020, as Germany's solar boost accelerated, and also put afternoon prices under pressure generally.”

The report also highlighted two instances of scarce electricity–in mid September and on December 9–as evidence of the problems associated with accommodating a rising proportion of intermittent clean energy capacity into the grid, and called for more joined-up cross-border power networks, amid pushback from Russian oil and gas across the continent.

Rising solar generation–along with higher gas output, year on year–also helped the Netherlands generate a net surplus of electricity last year, after being a net importer “for many years.” The EU report also noted a beneficial effect of rising solar generation capacity on Hungary‘s national electricity account, and cited a solar “boom” in that country and Poland, mirroring rapid solar PV growth in China in recent years.

With Covid-19 falls in demand helping renewables generate more of Europe's electricity (39%) than fossil fuels (36%) for the first time, as renewables surpassed fossil fuels across Europe, the market report observed the 5% of the bloc's power produced from solar closed in on the 6% accounted for by hard coal. In the final three months of the year, European solar output rose 12%, year on year, to 18 TWh and “the increase was almost single-handedly driven by Spain,” the study added.

With coal and lignite-fired power plunging 22% last year across the bloc, it is estimated the European power sector reduced its carbon footprint 14% as part of Europe's green surge although the quarterly report warned cold weather, lower wind speeds and rising gas prices in the opening months of this year are likely to see carbon emissions rebound.

There was good news on the transport front, though, with the report stating the scale of the European “electrically-charged vehicle” fleet doubled in 2020, to 2 million, with almost half a million of the new registrations arriving in the final months of the year. That meant cars with plug sockets accounted for a remarkable 17% of new purchases in Q4, twice the proportion seen in China and a slice of the pie six times bigger than such products claimed in the U.S.

Restrict price charged for gas and electricity - British MPs

UK Energy Price Cap aims to protect consumers on gas and electricity bills, tackling Big Six overcharging on default and standard variable tariffs, with Ofgem and MPs pushing urgent reforms to the broken market.

 

Key Points

A temporary absolute limit on default energy tariffs to shield consumers from overcharging on gas and electricity bills.

✅ Caps standard variable and default tariffs to protect loyalty.

✅ Targets Big Six pricing; oversight by Ofgem and BEIS MPs.

✅ Aims for winter protection while maintaining competition.

 

MPs are calling for a cap on the price of gas and electricity, with questions over the expected cost of a UK price cap amid fears consumers are being ripped off.

The Business, Energy and Industrial Strategy (BEIS) Select Committee says the Big Six energy companies have been overcharging for years.

MPs on the committee backed plans for a temporary absolute cap, noting debates over EU gas price cap strategies to fix what they called a "broken" energy market.

Labour's Rachel Reeves, who chairs the committee, said: "The energy market is broken. Energy is an essential good and yet millions of customers are ripped off for staying loyal to their energy provider.

"An energy price cap is now necessary and the Government must act urgently to ensure it is in place to protect customers next winter.

"The Big Six energy companies might whine and wail about the introduction of a price cap but they've been overcharging their customers on default and SVTs (standard variable tariffs) for years and their recent feeble efforts to move consumers off these tariffs has only served to highlight the need for this intervention."

The Committee also criticised Ofgem for failing to protect customers, especially the most vulnerable.

Draft legislation for an absolute cap on energy tariffs was published by the Government last year, and later developments like the Energy Security Bill have kept reform on the agenda.

But Business Secretary Greg Clark refused to guarantee that the flagship plans would be in place by next winter, despite warnings about high winter energy costs for households.

Committee members said there was a "clear lack of will" on the part of the Big Six to do what was necessary, including exploring decoupling gas and electricity prices, to deal with pricing problems.

A report from the committee found that customers are paying £1.4bn a year more than they should be under the current system.

Around 12 million households are stuck on poor-value tariffs, according to the report.

National assistance charity Citizens Advice said "loyal and vulnerable" customers had been "ripped off" for too long.

Chief executive Gillian Guy said: "An absolute cap, as recommended by the committee, is crucial to securing protection for the largest number of customers while continuing to provide competition in the market. This should apply to all default tariffs."

Mexican president's contentious electricity overhaul defeated in Congress

Mexico Energy Reform Defeat underscores opposition unity as CFE-first rules, state regulators, and lithium nationalization falter amid USMCA concerns, investment risks, and clean energy transition impacts in Congress over power generation policy.

 

Key Points

The failed push to expand CFE control, flagged for USMCA risks, higher costs, regulator shifts, and slower clean energy transition.

✅ Bill to mandate 54% CFE generation and priority dispatch failed.

✅ Opposition cited USMCA breaches, higher prices, slower clean energy.

✅ Lithium nationalization to return via separate legislation.

 

Mexican President Andres Manuel Lopez Obrador's plan to increase state control of power generation was defeated in parliament on Sunday, as opposition parties united in the face of a bill they said would hurt investment and breach international obligations, concerns mirrored by rulings such as the Florida court on electricity monopolies that scrutinize market concentration.

His National Regeneration Movement (MORENA) and its allies fell nearly 60 votes short of the two-thirds majority needed in the 500-seat lower house of Congress, mustering just 275 votes after a raucous session that lasted more than 12 hours.

Seeking to roll back previous constitutional reforms that liberalized the electricity market, Lopez Obrador's proposed changes would have done away with a requirement that state-owned Comision Federal de Electricidad (CFE) sell the cheapest electricity first, a move reminiscent of debates when energy groups warned on pricing changes under federal proposals, allowing it to sell its own electricity ahead of other power companies.

Under the bill, the CFE would also have been set to generate a minimum of 54% of the country's total electricity, and energy regulation would have been shifted from independent bodies to state regulators, paralleling concerns raised when a Calgary retailer opposed a market overhaul over regulatory impacts.

The contentious proposals faced much criticism from business groups and the United States, Mexico's top trade partner as well as other allies who argued it would violate the regional trade deal, the United States-Mexico-Canada Agreement (USMCA), even as the USA looks to Canada for green power to deepen cross-border energy ties.

Lopez Obrador had argued the bill would have protected consumers and made the country more energy independent, echoing how Texas weighs market reforms to avoid blackouts to bolster reliability, saying the legislation was vital to his plans to "transform" Mexico.

Although the odds were against his party, he came into the vote seeking to leverage his victory in last weekend's referendum on his leadership.

Speaking ahead of the vote, Jorge Alvarez Maynez, a lawmaker from the opposition Citizens' Movement party, said the proposals, if enacted, would damage Mexico, pointing to experiences like the Texas electricity market bailout after a severe winter storm as cautionary examples.

"There isn't a specialist, academic, environmentalist or activist with a smidgen of doubt - this bill would increase electricity prices, slow the transition to (clean) energy in our country and violate international agreements," he added.

Supporters of clean-energy goals noted that subnational shifts, such as the New Mexico 100% clean electricity bill can illustrate alternative pathways to reform.

The bill also contained a provision to nationalize lithium resources.

Lopez Obrador said this week that if the bill was defeated, he would send another bill to Congress on Monday aiming to have at least the lithium portion of the proposed legislation passed.

Wind and solar make more electricity than nuclear for first time in UK

UK Renewables Surpass Nuclear Milestone as wind farms and solar panels outpace atomic output, cutting greenhouse gas emissions. BEIS data show low-carbon power generation rising while onshore wind subsidies and auction timelines face policy debate.

 

Key Points

It is the quarter when UK wind and solar generated more electricity than nuclear, signaling cleaner, low-carbon growth.

✅ BEIS reports wind and solar at 18.33 TWh vs nuclear 16.69 TWh

✅ Energy sector emissions fell 8% as coal use dropped

✅ Calls grow to reopen onshore wind support via CFD auctions

 

Wind farms and solar panels, with wind leading the power mix during key periods, produced more electricity than the UK’s eight nuclear power stations for the first time at the end of last year, official figures show.

Britain’s greenhouse gas emissions also continued to fall, dropping 3% in 2017, as coal use fell and the use of renewables climbed, though low-carbon generation stalled in 2019 according to later data.

Energy experienced the biggest drop in emissions of any UK sector, of 8%, while pollution from transport and businesses stayed flat.

Energy industry chiefs said the figures showed that the government should rethink its ban on onshore wind subsidies, a move that ministers have hinted could happen soon.

Lawrence Slade, chief executive of the big six lobby group Energy UK, said: “We need to keep up the pace ... by ensuring that the lowest cost renewables are no longer excluded from the market.”

Across the whole year, low-carbon sources of power – wind, solar, biomass and nuclear – provided a record 50.4% of electricity, up from 45.7% in 2016, when wind beat coal for the first time.

But in the fourth quarter of 2017, high wind speeds, new renewables installations and lower nuclear output saw wind and solar becoming the second biggest source of power for the first time.

Wind and solar generated 18.33 terawatt hours (TWh), with nuclear on 16.69TWh, and the UK later set a new record for wind power during 2019, the figures published by the Department for Business, Energy and Industrial Strategy show.

But renewables still have a long way to go to catch up with gas, the UK’s top source of electricity at 36.12TWh, which saw its share of generation fall slightly, though at times wind became the main source as capacity expanded.

Greenpeace said the figures showed the government should capitalise on its lead in renewables and “stop wasting time and money propping up nuclear power”.

Horizon Nuclear Power, a subsidiary of the Japanese conglomerate Hitachi, is in talks with Whitehall officials for a financial support package from the government, which it says it needs by midsummer.

By contrast, large-scale solar and onshore wind projects are not eligible for support, after the Conservative government cut subsidies in 2015.

However the energy minister, Claire Perry, recently told House Magazine that “we will have another auction that brings forward wind and solar, we just haven’t yet said when”.

Ontario to seek new wind, solar power to help ease coming electricity supply crunch

Ontario Clean Grid Plan outlines emissions-free electricity growth, renewable energy procurement, nuclear expansion at Bruce and Darlington, reduced natural gas, grid reliability, and net-zero alignment to meet IESO demand forecasts and EV manufacturing loads.

 

Key Points

A plan to expand emissions-free power via renewables and nuclear, cut natural gas use, and meet growing demand.

✅ Targets renewables, hydro, and nuclear capacity growth

✅ Aims to reduce reliance on gas for grid reliability

✅ Aligns with IESO demand forecasts and EV manufacturing loads

 

Ontario is working toward filling all of the province’s quickly growing electricity needs with emissions-free sources, including a plan to secure new renewable generation and clean power options, but isn’t quite ready to commit to a moratorium on natural gas.

Energy Minister Todd Smith announced Monday a plan to address growing energy needs for 2030 to 2050 — the Independent Electricity System Operator projects Ontario’s electricity demand could double by mid-century — and next steps involve looking for new wind, solar and hydroelectric power.

“While we may not need to start building today, government and those in the energy sector need to start planning immediately, so we have new clean, zero-emissions projects ready to go when we need them,” Smith said in Windsor, Ont.

The strategy also includes two nuclear projects announced last week — a new large-scale nuclear plant at Bruce Power on the shore of Lake Huron and three new small modular reactors at the site of the Darlington nuclear plant east of Toronto.

Those projects, enough to power six million homes, will help Ontario end its reliance on natural gas to generate electricity, said Smith, but committing to a natural gas moratorium in 2027 and eliminating natural gas by 2050 is contingent on the federal government helping to speed up the new nuclear facilities.

“Today’s report, the Powering Ontario’s Growth plan, commits us to working towards a 100 per cent clean grid,” Smith said in an interview.

“Hopefully the federal government can get on board with our intentions to build this clean generation as quickly as possible … That will put us in a much better position to use our natural gas facilities less in the future, if we can get those new projects online.”

The IESO has said that natural gas is required to ensure supply and stability in the short to medium term, as Ontario works on balancing demand and emissions across the grid, but that it will also increase greenhouse gas emissions from the electricity sector.

The province is expected to face increased demand for electricity from expanded electric vehicle use and manufacturing in the coming years, even as a $400-billion cost estimate for greening the grid is debated.

Keith Brooks, programs director for Environmental Defence, said the provincial plan could have been much more robust, containing firm timelines and commitments.

“This plan does not commit to getting emissions out of the system,” he said.

“It doesn’t commit to net zero, doesn’t set a timeline for a net zero goal or have any projection around emissions from Ontario’s electricity sector going forward. In fact, it’s not really a plan. It doesn’t set out any real goals and it doesn’t it doesn’t project what Ontario’s supply mix might look like.”

The Canadian Climate Institute applauded the plan’s focus on reducing reliance on gas-fired generation and emphasizing non-emitting generation, but also said there are still some question marks.

“The plan is silent on whether the province intends to construct new gas-fired generation facilities,” even as new gas plant expansions are proposed, senior research director Jason Dion wrote in a statement.

“The province should avoid building new gas plants since cost-effective alternatives are available, and such facilities are likely to end up as stranded assets. The province’s timeline for reaching net zero generation is also unclear. Canada and other G7 countries have set a target for 2035, something Ontario will need to address if it wants to remain competitive.”

Electricity Prices in France Turn Negative

Negative Electricity Prices in France signal oversupply from wind and solar, stressing the wholesale market and grid. Better storage, demand response, and interconnections help balance renewables and stabilize prices today.

 

Key Points

They occur when renewable output exceeds demand, pushing power prices below zero as excess energy strains the grid.

✅ Driven by wind and solar surges with low demand

✅ Challenges thermal plants; erodes margins at negative prices

✅ Needs storage, demand response, and cross-border interties

 

France has recently experienced an unusual and unprecedented situation in its electricity market: negative electricity prices. This development, driven by a significant influx of renewable energy sources, highlights the evolving dynamics of energy markets as countries increasingly rely on clean energy technologies. The phenomenon of negative pricing reflects both the opportunities and renewable curtailment challenges associated with the integration of renewable energy into national grids.

Negative electricity prices occur when the supply of electricity exceeds demand to such an extent that producers are willing to pay consumers to take the excess energy off their hands. This situation typically arises during periods of high renewable energy generation coupled with low energy demand. In France, this has been driven primarily by a surge in wind and solar power production, which has overwhelmed the grid and created an oversupply of electricity.

The recent surge in renewable energy generation can be attributed to a combination of favorable weather conditions and increased capacity from new renewable energy installations. France has been investing heavily in wind and solar energy as part of its commitment to reducing greenhouse gas emissions and transitioning towards a more sustainable energy system, in line with renewables surpassing fossil fuels in Europe in recent years. While these investments are essential for achieving long-term climate goals, they have also led to challenges in managing energy supply and demand in the short term.

One of the key factors contributing to the negative prices is the variability of renewable energy sources. Wind and solar power are intermittent by nature, meaning their output can fluctuate significantly depending on weather conditions, with solar reshaping price patterns in Northern Europe as deployment grows. During times of high wind or intense sunshine, the electricity generated can far exceed the immediate demand, leading to an oversupply. When the grid is unable to store or export this excess energy, prices can drop below zero as producers seek to offload the surplus.

The impact of negative prices on the energy market is multifaceted. For consumers, negative prices can lead to lower energy costs as wholesale electricity prices fall during oversupply, and even potential credits or payments from energy providers. This can be a welcome relief for households and businesses facing high energy bills. However, negative prices can also create financial challenges for energy producers, particularly those relying on conventional power generation methods. Fossil fuel and nuclear power plants, which have higher operating costs, may struggle to compete when prices are negative, potentially affecting their profitability and operational stability.

The phenomenon also underscores the need for enhanced energy storage and grid management solutions. Excess energy generated from renewable sources needs to be stored or redirected to maintain grid stability and avoid negative pricing situations. Advances in battery storage technology, such as France's largest battery storage platform, and improvements in grid infrastructure are essential to addressing these challenges and optimizing the integration of renewable energy into the grid. By developing more efficient storage solutions and expanding grid capacity, France can better manage fluctuations in renewable energy production and reduce the likelihood of negative prices.

France's experience with negative electricity prices is part of a broader trend observed in other countries with high levels of renewable energy penetration. Similar situations have occurred in Germany, where solar plus storage is now cheaper than conventional power, the United States, and other regions where renewable energy capacity is rapidly expanding. These instances highlight the growing pains associated with transitioning to a cleaner energy system and the need for innovative solutions to balance supply and demand.

The French government and energy regulators are closely monitoring the situation and exploring measures to mitigate the impact of negative prices. Policy adjustments, market reforms, and investments in energy infrastructure are all potential strategies to address the challenges posed by high renewable energy generation. Additionally, encouraging the development of flexible demand response programs and enhancing grid interconnections with neighboring countries can help manage excess energy and stabilize prices.

In the long term, the rise of renewable energy and the occurrence of negative prices represent a positive development for the energy transition. They indicate progress towards cleaner energy sources and a more sustainable energy system. However, managing the associated challenges is crucial for ensuring that the transition is smooth and economically viable for all stakeholders involved.

In conclusion, the recent instance of negative electricity prices in France highlights the complexities of integrating renewable energy into the national grid. While the phenomenon reflects the success of France’s efforts to expand its renewable energy capacity, it also underscores the need for advanced grid management and storage solutions. As the country continues to navigate the transition to a more sustainable energy system, addressing these challenges will be essential for maintaining a stable and efficient energy market. The experience serves as a valuable lesson for other nations undergoing similar transitions and reinforces the importance of innovation and adaptability in the evolving energy landscape.
