KUB's board of commissioners considered two proposals meant to help the local utility accommodate TVA efforts to deal with increasing peak power demand, with one plan likely to bring changes to electric bills but with no real change in what customers actually pay, according to KUB officials.

The KUB board approved on first reading a proposal that allows its large industrial customers to take part in a TVA program encouraging them to shift their electric power demand use to non-peak hours.

The board also heard a KUB staff presentation on ways KUB can adjust its retail rate structure to accept changes TVA has approved to its wholesale rate structure. This will involve billing changes that will be complicated for KUB but of little consequence for customers, said Sherri Johnson, manager of rates for KUB.

The board also elected officers for 2011 and swore in Nikitia Thompson to her second term as a KUB commissioner. Pace Robinson was re-elected as chair, Eston Williams was re-elected vice chair and Mark Walker was elected secretary.

Ed Medford, KUB manager of key accounts, told the board that about 11 large industrial customers are eligible to join the Two-Part Real Time Pricing program that TVA has developed. This allows industrial customers to pay a fixed rate for a base level of hourly power use, and any variation in usage is charged or credited to the customer based on TVA's cost of producing the power. Participation by KUB's industrial customers would have no effect on KUB revenues, Medford said. The board approved the proposal after some commissioners received assurances that KUB would not face any hidden costs. The measure will take effect in March if also approved at the February meeting.

Johnson gave the board a presentation on a proposed new retail rate schedule that will come before the board for readings in February and March. Currently, KUB pays TVA a monthly power bill based on the total of power sales to KUB customers and that takes into account both energy and demand at rates that vary by KUB's customer classifications, Johnson said.

Under TVA's new system, KUB would be billed for its total monthly electric use and will be responsible for recovering the appropriate costs from its customers.

Also, TVA's new rate structure will include seasonal rates that will change to reflect higher costs of power generation during the summer. KUB is revising its retail rate structure to accommodate these changes, Johnson said. This includes a proposed increase in basic service charges for residential and small commercial customers to be offset by reductions to these customers' energy rates.

This should allow KUB to accommodate the new TVA rate structure without taking in additional revenue from customers, she said.

The new KUB rate schedule will take effect in May if approved on both readings.

Can Europe's atomic reactors bridge the gap to an emissions-free future?

EU Nuclear Reactor Life Extension focuses on energy security, carbon-free electricity, and safety as ageing reactors face gas shortages, high power prices, and regulatory approvals across the UK and EU amid winter supply risks.

 

Key Points

EU Nuclear Reactor Life Extension is the policy to keep ageing reactors safely generating affordable, low-carbon power.

✅ Extends reactor operation via inspections and component upgrades

✅ Addresses gas shortages, price volatility, and winter supply risks

✅ Requires national regulator approval and cost-benefit analysis

 

Shaken by the loss of Russian natural gas since the invasion of Ukraine, European countries are questioning whether they can extend the lives of their ageing nuclear reactors to maintain the supply of affordable, carbon-free electricity needed for net-zero across the bloc — but national regulators, companies and governments disagree on how long the atomic plants can be safely kept running.

Europe avoided large-scale blackouts last winter despite losing its largest supplier of natural gas, and as Germany temporarily extended nuclear operations to bolster stability, but industry is still grappling with high electricity prices and concerns about supply.

Given warnings from the International Energy Agency that the coming winters will be particularly at risk from a global gas shortage, governments have turned their attention to another major energy source — even as some officials argue nuclear would do little to solve the gas issue in the near term — that would exacerbate the problem if it too is disrupted: Europe’s ageing fleet of nuclear power plants.

Nuclear accounts for nearly 10% of energy consumed in the European Union, with transport, industry, heating and cooling traditionally relying on coal, oil and natural gas.

Historically nuclear has provided about a quarter of EU electricity and 15% of British power, even as Germany shut down its last three nuclear plants recently, underscoring diverging national paths.

Taken together, the UK and EU have 109 nuclear reactors running, even as Europe is losing nuclear power in several markets, most of which were built in the 1970s and 1980s and were commissioned to last about 30 years.

That means 95 of those reactors — nearly 90% of the fleet — have passed or are nearing the end of their original lifespan, igniting debates over how long they can safely continue to be granted operating extensions, with some arguing it remains a needed nuclear option for climate goals despite age-related concerns.

Regulations differ across borders, with some countries such as Germany turning its back on nuclear despite an ongoing energy crisis, but life extension discussions are usually a once-a-decade affair involving physical inspections, cost/benefit estimates for replacing major worn-out parts, legislative amendments, and approval from the national nuclear safety authority.

City of Vancouver named Clean Energy Champion for Bloedel upgrades

BC Hydro Clean Energy Champions highlights Vancouver's Bloedel Conservatory electrification with a massive heat pump, clean electricity, LED lighting, deep energy efficiency, and 90% greenhouse gas reductions advancing climate action across buildings and industry.

 

Key Points

A BC Hydro program honoring clean electricity adoption in homes, transport, and industry to replace fossil fuels.

✅ Vancouver's Bloedel Conservatory cut GHGs by 90% with a heat pump

✅ LEDs and electrification boost efficiency, comfort, and reliability

✅ Nominations open for residents, businesses, and Indigenous groups

 

The City of Vancouver has been selected as BC Hydro’s first Clean Energy Champion for energy efficient upgrades made at the Bloedel Conservatory that cut greenhouse gas emissions by 90 per cent, a meaningful step given concerns about 2050 greenhouse gas targets in B.C.

BC Hydro’s Clean Energy Champions program is officially being launched today to recognize residents, businesses, municipalities, Indigenous and community groups across B.C. that have made the choice to switch from using fossil fuels to using clean electricity in three primary areas: homes and buildings, transportation, and industry, even as drought challenges power generation in B.C. The City of Vancouver is being recognized as the first champion for demonstrating its commitment to using clean energy, including power from projects like Site C's electricity, to fight climate change at its landmark Bloedel Conservatory.

Earlier this year, the City of Vancouver installed a large air source heat pump at Bloedel Conservatory – more than 50 times the size of a heat pump used in a typical B.C. home – that uses electricity instead of natural gas to heat and cool the dome's interior, which is home to more than 500 exotic plants and flowers, and 100 exotic birds, aligning with citywide debates such as Vancouver’s reversal on gas appliances policy. It is the biggest heat pump the City of Vancouver has ever installed, with 210 tonnes of cooling capacity.

A heat pump that provides cooling in the summer and heating in the winter, helping reduce reliance on wasteful air conditioning that can drive up energy bills, is ideal for the conservatory, as its dome is completely made of glass, which can be challenging for temperature regulation. While the dome experiences a lot of heat loss in the colder months, its need for cooling in warmer weather is even greater to ensure the safety of the wildlife and plants that call it home.

The clean energy upgrades do not end there though. All lighting in the building has been upgraded to energy-efficient LEDs, reflecting conservation themes highlighted by 2018 Earth Hour electricity use discussions, and outside colour-changing LEDs now surround the perimeter and light up the dome at night.

BC Hydro is calling for nominations from B.C. residents, businesses, municipalities or Indigenous and community groups that have taken steps to lower their carbon footprint and adopt new clean energy technologies, and continues to support customers through programs like its winter payment plan during colder months. If you or someone you know is a Clean Energy Champion, nominate them at bchydro.com/cleanenergychampions.

Federal net-zero electricity regulations will permit some natural gas power generation

Canada Clean Electricity Regulations allow flexible, technology-neutral pathways to a 2035 net-zero grid, permitting limited natural gas with carbon capture, strict emissions standards, and exemptions for emergencies and peak demand across provinces and territories.

 

Key Points

Federal draft rules for a 2035 net-zero grid, allowing limited gas with CCS under strict performance and compliance standards.

✅ Performance cap: 30 tCO2 per GWh annually for gas plants

✅ CCS must sequester 95% of emissions to comply

✅ Emergency and peak demand exemptions permitted

 

After facing pushback from Alberta and Saskatchewan, and amid looming power challenges nationwide, Canada's draft net-zero electricity regulations — released today — will permit some natural gas power generation. 

Environment Minister Steven Guilbeault released Ottawa's proposed Clean Electricity Regulations on Thursday.

Provinces and territories will have a minimum 75-day window to comment on the draft regulations. The final rules are intended to pave the way to a net-zero power grid in Canada, aligning with 2035 clean electricity goals established nationally. 

Calling the regulations "technology neutral," Guilbeault said the federal government believes there's enough flexibility to accommodate the different energy needs of Canada's diverse provinces and territories, including how Ontario is embracing clean power in its planning. 

"What we're talking about is not a fossil fuel-free grid by 2035; it's a net zero grid by 2035," Guilbeault said. 

"We understand there will be some fossil fuels remaining … but we're working to minimize those, and the fossil fuels that will be used in 2035 will have to comply with rigorous environmental and emission standards," he added. 

Some analysts argue that scrapping coal-fired electricity can be costly and ineffective, underscoring the trade-offs in transition planning.

While non-emitting sources of electricity — hydroelectricity, wind and solar and nuclear — should not have any issues complying with the regulations, natural gas plants will have to meet specific criteria.

Those operations, the government said, will need to emit the equivalent of 30 tonnes of carbon dioxide per gigawatt hour or less annually to help balance demand and emissions across the grid.

Federal officials said existing natural gas power plants could comply with that performance standard with the help of carbon capture and storage systems, which would be required to sequester 95 per cent of their emissions.

"In other words, it's achievable, and it is achievable by existing technology," said a government official speaking to reporters Thursday on background and not for attribution.

The regulations will also allow a certain level of natural gas power production without the need to capture emissions. Capturing emissions will be exempted during emergencies and peak periods when renewables cannot keep up with demand. 

Some newer plants might not have to comply with the rules until the 2040s, because the regulations apply to plants 20 years after they are commissioned, which dovetails with net-zero by 2050 commitments from electricity associations. 

The two-decade grace period does not apply to plants that open after the regulations are expected to be finalized in 2025.

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.

New clean energy investment in developing nations slipped sharply last year: report

Developing Countries Clean Energy investment fell as renewable energy financing slowed in China; solar and wind growth lagged while coal power hit new highs, raising emissions risks for emerging markets and complicating climate change goals.

 

Key Points

Renewables investment and power trends in emerging nations: solar, wind, coal shifts, and steps toward decarbonization.

✅ Investment fell to $133b; China dropped to $86b

✅ Coal power rose to 6,900 TWh; 47% generation share

✅ New coal builds declined to 39 GW, decade low

 

New clean energy investment slid by more than a fifth in developing countries last year due to a slowdown in China, while the amount of coal-fired power generation jumped to a new high, reflecting global power demand trends, a recent annual survey showed.

Bloomberg New Energy Finance (BNEF) surveyed 104 emerging markets and found that developing nations were moving towards cleaner, low-emissions sources in many regions, but not fast enough to limit carbon dioxide emissions or the effects of climate change.

New investment in wind, solar and other clean energy projects dropped to $133 billion last year from $169 billion a year earlier, mainly due to a slump in Chinese investment, even as electricity investment globally surpasses oil and gas for the first time, the research showed.

China’s clean energy investment fell to $86 billion from $122 billion a year earlier, with dynamics in China's electricity sector also in focus. Investment by India and Brazil also declined, mainly due to lower costs for solar and wind.

However, the volume of coal-fired power generation produced and consumed in developing countries increased to a new high of 6,900 terrawatt hours (TWh) last year, even as renewables are poised to eclipse coal globally, from 6,400 TWh in 2017.

The increase of 500 TWh is equivalent to the power consumed in the U.S. state of Texas in one year, underscoring how surging electricity demand is putting power systems under strain. Coal accounted for 47% of all power generation across the 104 countries.

“The transition from coal toward cleaner sources in developing nations is underway,” said Ethan Zindler, head of Americas at BNEF. “But like trying to turn a massive oil tanker, it takes time.”

Despite the spike in coal-fired generation, the amount of new coal capacity which was added to the grid in developing countries declined, with Europe's renewables crowding out gas offering a contrasting pathway. New construction of coal plants fell to its lowest level in a decade last year of 39 gigawatts (GW).

The report comes a week ahead of United Nations climate talks in Madrid, Spain, where more than 190 countries will flesh out the details of an accord to limit global warming.

BloombergNEF: World offshore wind costs 'drop 32% per cent'

Global Renewable LCOE Trends reveal offshore wind costs down 32%, with 10MW turbines, lower CAPEX and OPEX, and parity for solar PV and onshore wind in Europe, China, and California, per BloombergNEF analysis.

 

Key Points

Benchmarks showing falling LCOE for offshore wind, onshore wind, and solar PV, driven by larger turbines and lower CAPEX

✅ Offshore wind LCOE $78/MWh; $53-64/MWh in DK/NL excl. transmission

✅ Onshore wind $47/MWh; solar PV $51/MWh, best $26-36/MWh

✅ Cost drivers: 10MW turbines, lower CAPEX/OPEX, weak China demand

 

World offshore wind costs have fallen 32% from just a year ago and 12% compared with the first half of 2019, according to a BNEF long-term outlook from BloombergNEF.

In its latest Levelized Cost of Electricity (LCOE) Update, BloombergNEF said its current global benchmark LCOE estimate for offshore wind is $78 a megawatt-hour.

“New offshore wind projects throughout Europe, including the UK's build-out, now deploy turbines with power ratings up to 10MW, unlocking CAPEX and OPEX savings,” BloombergNEF said.

In Denmark and the Netherlands, it expects the most recent projects financed to achieve $53-64/MWh excluding transmission.

New solar and onshore wind projects have reached parity with average wholesale power prices in California and parts of Europe, while in China levelised costs are below the benchmark average regulated coal price, according to BloombergNEF.

The company's global benchmark levelized cost figures for onshore wind and PV projects financed in the last six months are at $47 and $51 a megawatt-hours, underscoring that renewables are now the cheapest new electricity option in many regions, down 6% and 11% respectively compared with the first half of 2019.

BloombergNEF said for wind this is mainly down to a fall in the price of turbines – 7% lower on average globally compared with the end of 2018.

In China, the world’s largest solar market, the CAPEX of utility-scale PV plants has dropped 11% in the last six months, reaching $0.57m per MW.

“Weak demand for new plants in China has left developers and engineering, procurement and construction firms eager for business, and this has put pressure on CAPEX,” BloombergNEF said.

It added that estimates of the cheapest PV projects financed recently – in India, Chile and Australia – will be able to achieve an LCOE of $27-36/MWh, assuming competitive returns for their equity investors.

Best-in-class onshore wind farms in Brazil, India, Mexico and Texas can reach levelized costs as low as $26-31/MWh already, the research said.

Programs such as the World Bank wind program are helping developing countries accelerate wind deployment as costs continue to drop.

BloombergNEF associate in the energy economics team Tifenn Brandily said: “This is a three- stage process. In phase one, new solar and wind get cheaper than new gas and coal plants on a cost-of- energy basis.

“In phase two, renewables reach parity with power prices. In phase three, they become even cheaper than running existing thermal plants.

“Our analysis shows that phase one has now been reached for two-thirds of the global population.

“Phase two started with California, China and parts of Europe. We expect phase three to be reached on a global scale by 2030.

“As this all plays out, thermal power plants will increasingly be relegated to a balancing role, looking for opportunities to generate when the sun doesn’t shine or the wind doesn’t blow.”
