Colorado's rural electric cooperatives surrendered on the issue of renewable energy standards this year. But they claim they're not going to give in on another bill mandating much more "net metering."

That's a system that allows customers to generate their own electricity - using windmills or solar panels - and sell what they don't use back to their REA.

Under House Bill 1169, to the extent their meter spins backward, they would in most cases be paid the retail price of electricity. That's what drives the REAs crazy.

The REAs argue that if they have to pay retail for this electricity, while paying wholesale to Tri-State G&T (which generates power for 18 of Colorado's 22 REAs) and Xcel Energy (which supplies the other four), it would force the rest of their customers to pay more for their power.

"This bill allows huge subsidies for large agricultural producers and big box stores, and the subsidies have to be picked up by the remaining customers," argues Ray Clifton, executive director of the Colorado Rural Electric Association.

Net metering isn't new to the REAs. Legislation authorizing it was passed in 2002. But they had to offer only up to 25 kilowatts to a customer and the law didn't specify the price that the REAs must pay for the electricity. They were free to work out all sorts of different contracts with their net-metering customers.

But 1169 requires the smallest REAs to accommodate up to 500 kw (20 times the current law) of net metering per customer. REAs with 10,000 to 40,000 retail meters would have to offer up to 1 megawatt per customer and the five REAs with 40,000 or more meters would have to offer 2 MW.

Clifton was last seen standing behind Gov. Bill Ritter when he signed House Bill 1281 last month. That measure requires investor-owned utilities such as Xcel to generate 20 percent of their electricity from renewable sources by 2020 - twice what the voters demanded in 2004's Amendment 37. More to the point, HB 1281 requires the REAs to generate 10 percent of their power by renewables.

The REAs had managed to exempt themselves from Amendment 37's mandates. But when the Democrats took over the governorship as well as the legislature, most of the REAs saw what was coming and climbed, albeit reluctantly, on board the renewable energy train.

But they're fighting HB 1169, which has passed the House and is now before a Senate committee. It's being pushed by the wind and solar energy promoters and environmental groups who don't want Tri- State or Xcel building more coal plants. They figure if subsidizing net-metering forces some customers to pay more for power, too bad. You can't turn the planet into a better omelet without breaking eggs.

Still, there's a touch of irony in the fact that 1169 puts the enviros on the same side as Wal-Mart and the other large stores who want to appear "green" by generating their own power.

The REAs aren't controlled by the Public Utilities Commission. They are owned by their members and their net earnings are returned to them. What's more, the customers can run for election to their co-op's board and change policies they don't like.

Indeed Intermountain REA, the largest and most recalcitrant of the state's REAs, is being targeted by enviros who want to serve on the board.

Nothing wrong with that. With such democratic management REAs don't need legislative mandates. The new net-metering bill violates the ancient rule of "If it ain't broke don't fix it." The REAs, if left to themselves, would figure out their own ways to handle net metering.

Meanwhile, passions are running high. Clifton was hauled in and lectured by House leadership because sponsoring Rep. Judy Solano, D-Brighton, complained his fact sheet understated the amount of negotiating she was willing to do with the REAs.

N.L., Ottawa agree to shield ratepayers from Muskrat Falls cost overruns

Muskrat Falls Financing Restructuring redirects megadam benefits to ratepayers, stabilizes electricity rates, and overhauls federal provincial loan guarantees for the hydro project, addressing cost overruns flagged by the Public Utilities Board in Newfoundland and Labrador.

 

Key Points

A revised funding model shifting benefits to ratepayers to curb rate hikes linked to Muskrat Falls cost overruns.

✅ Shields ratepayers from megadam cost overruns

✅ Revises federal provincial loan guarantees

✅ Targets stable electricity rates by 2021 and beyond

 

Ottawa and Newfoundland and Labrador say they will rewrite the financial structure of the Muskrat Falls hydro project to shield ratepayers from paying for the megadam's cost overruns.

Federal Natural Resources Minister Seamus O'Regan and Premier Dwight Ball announced Monday that their two governments would scrap the financial structure agreed upon in past federal-provincial loan agreements, moving to a model that redirects benefits, such as a lump sum credit, to ratepayers.

Both politicians called the announcement, which was light on dollar figures, a major milestone in easing residents' fears that electricity rates will spike sharply, as seen with Nova Scotia's debated 14% hike, when the over-budget dam comes fully online next year.
"We are in a far better place today thanks to this comprehensive plan," Ball said.

Ball has said the issue of electricity rates is a top priority for his government, and he has pledged to keep rates near existing levels, but rate mitigation talks with Ottawa have dragged on since April.

A report by the province's Public Utilities Board released Friday forecast an "unprecedented" 75 per cent increase in average domestic rates for island residents in 2021, while Nova Scotia's regulator approved a 14% hike, and reported concerns from industrial customers about their ability to remain competitive.

Costs of the Muskrat Falls megadam on Labrador's Lower Churchill River have ballooned to more than $12.7 billion since the project was approved in 2012, according to the latest estimate of Crown corporation Nalcor Energy.

The dam is set to produce more power than the province can sell. Its existing financial structure would have left electricity ratepayers paying for Muskrat Falls to make up the difference starting in 2021, an issue both governments said Monday has been resolved with the relaunch of financing talks.

"Essentially, you won't pay this on your monthly light bills," Ball said.

But details of how the project will meet financing requirements in coming decades to make up the gap in funds are still to be worked out.

Both Ball and O'Regan criticized previous governments for sanctioning the poorly planned development and again pledged their commitment to easing the burden on residents.

"We promised we would be there to help, and we will be," O'Regan said before announcing a "relaunch" of negotiations around the project's financial structure.

He did not say how much the new setup might cost the federal government, despite earlier federal funding commitments, stressing that the new focus will be on the project's long-term sustainability. "There's no single piece of policy ... that can resolve such a large and complicated mess," O'Regan said.

The two governments also said they will work towards electrifying federal buildings to reduce an anticipated power surplus in the province.

In the short term, the federal government said it would allow for "flexibility" in upcoming cash requirements related to debt servicing, allowing deferral of payments if necessary.

Ball said that flexibility was built in to ensure the plan would still be applicable if costs continue to rise before Muskrat Falls is commissioned.

Political opponents criticized Monday's plan as lacking detail.

"What I heard talked about was an agreement that in the future, there's going to be an agreement," said Progressive Conservative Leader Ches Crosbie. "This was an occasion to reassure people that there's a plan in place to make life here affordable, and I didn't see that happen today."

Others addressed the lingering questions about the project's final cost.

Nalcor's latest financial update has remained unchanged since 2017, though the Muskrat Falls project has seen additional delays related to staffing and software issues.

Dennis Browne, the province's consumer advocate, said the switch to a cost of service model is a significant move that will benefit ratepayers, but he said it's impossible to truly restructure the project while it's a work in progress. "We need to know what the figures are, and we don't have them," he said.

Britain got its cleanest electricity ever during lockdown

UK Clean Electricity Record as wind, solar, and biomass boost renewable energy output, slashing carbon emissions and wholesale power prices during lockdown, while lower demand challenges grid balancing and drives a drop to 153 g/kWh.

 

Key Points

A milestone where wind, solar and biomass lifted renewables, cutting carbon intensity to 153 g/kWh during lockdown.

✅ Carbon intensity averaged 153 g/kWh in Q2 2020.

✅ Renewables output rose 32% via wind, solar, biomass.

✅ Wholesale power prices slumped 42% amid lower demand.

 

U.K electricity has never been cleaner. As wind, solar and biomass plants produced more power than ever in the second quarter, with a new wind generation record set, carbon emissions fell by a third from a year earlier, according to Drax Electric Insight’s quarterly report. Power prices slumped 42 per cent as demand plunged during lockdown. Total renewable energy output jumped 32 per cent in the period, as wind became the main source of electricity at times.

“The past few months have given the country a glimpse into the future for our power system, with higher levels of renewable energy, as wind led the power mix, and lower demand making for a difficult balancing act,”said  Iain Staffell, from Imperial College London and lead author of the report.

The findings of the report point to the impact energy efficiency can have on reducing emissions, as coal's share fell to record lows across the electricity system. Millions of people furloughed or working from home and shuttered shops up and down the country resulted in daily electricity demand dropping about 10% and being about four gigawatts lower than expected in the three months through June.

Average carbon emissions fell to a new low of 153 grams per kWh of electricity consumed over the quarter, as coal-free generation records were extended, even though low-carbon generation stalled in 2019, according to the report.

ETP 2017 maps major transformations in energy technologies

Global Energy Electrification drives IEA targets as smart grids, storage, EVs, and demand-side management scale. Paris Agreement-aligned policies and innovation accelerate decarbonization, enabling flexible, low-carbon power systems and net-zero pathways by 2060.

 

Key Points

A shift to electricity across sectors via smart grids, storage, EVs, and policy to cut CO2 and improve energy security.

✅ Smart grids, storage, DSM enable flexible, resilient power.

✅ Aligns with IEA pathways and Paris Agreement goals.

✅ Drives EV adoption, building efficiency, and net-zero by 2060.

 

The global energy system is changing, with European electricity market trends highlighting rapid shifts. More people are connecting to the grid as living standards improve around the world. Demand for consumer appliances and electronic devices is rising. New and innovative transportation technologies, such as electric vehicles and autonomous cars are also boosting power demand.

The International Energy Agency's latest report on energy technologies outlines how these and other trends as well as technological advances play out in the next four decades to reshape the global energy sector.

Energy Technology Perspectives 2017 (ETP) highlights that decisive policy actions and market signals will be needed to drive technological development and benefit from higher electrification around the world. Investments in stronger and smarter infrastructure, including transmission capacity, storage capacity and demand side management technologies such as demand response programs are necessary to build efficient, low-carbon, integrated, flexible and robust energy system. 

Still, current government policies are not sufficient to achieve long-term global climate goals, according to the IEA analysis, and warnings about falling global energy investment suggest potential supply risks as well. Only 3 out of 26 assessed technologies remain “on track” to meet climate objectives, according to the ETP’s Tracking Clean Energy Progress report. Where policies have provided clean signals, progress has been substantial. However, many technology areas suffer from inadequate policy support. 

"As costs decline, we will need a sustained focus on all energy technologies to reach long-term climate targets," said IEA Executive Director Dr Fatih Birol. "Some are progressing, but too few are on track, and this puts pressure on others. It is important to remember that speeding the rate of technological progress can help strengthen economies, boost energy security while also improving energy sustainability."

ETP 2017’s base case scenario, known as the Reference Technology Scenario (RTS), takes into account existing energy and climate commitments, including those made under the Paris Agreement. Another scenario, called 2DS, shows a pathway to limit the rise of global temperature to 2ºC, and finds the global power sector could reach net-zero CO2 emissions by 2060.

A second decarbonisation scenario explores how much available technologies and those in the innovation pipeline could be pushed to put the energy sector on a trajectory beyond 2DS. It shows how the energy sector could become carbon neutral by 2060 if known technology innovations were pushed to the limit. But to do so would require an unprecedented level of policy action and effort from all stakeholders.

Looking at specific sectors, ETP 2017 finds that buildings could play a major role in supporting the energy system transformation. High-efficiency lighting, cooling and appliances could save nearly three-quarters of today’s global electricity demand between now and 2030 if deployed quickly. Doing so would allow a greater electrification of the energy system that would not add burdens on the system. In the transportation system, electrification also emerges as a major low-carbon pathway, with clean grids and batteries becoming key areas to watch in deployment.

The report finds that regardless of the pathway chosen, policies to support energy technology innovation at all stages, from research to full deployment, alongside evolving utility trends that operators need to watch, will be critical to reap energy security, environmental and economic benefits of energy system transformations. It also suggests that the most important challenge for energy policy makers will be to move away from a siloed perspective towards one that enables systems integration.

Why Nuclear Fusion Is Still The Holy Grail Of Clean Energy

Nuclear fusion breakthrough signals progress toward clean energy as NIF lasers near ignition and net energy gain, while tokamak designs like ITER advance magnetic confinement, plasma stability, and self-sustaining chain reactions for commercial reactors.

 

Key Points

A milestone as lab fusion nears ignition and net gain, indicating clean energy via lasers and tokamak confinement.

✅ NIF laser shot approached ignition and triggered self-heating

✅ Tokamak path advances with ITER and stronger magnetic confinement

✅ Net energy gain remains the critical milestone for power plants

 

Just 100 years ago, when English mathematician and astronomer Arthur Eddington suggested that the stars power themselves through a process of merging atoms to create energy, heat, and light, the idea was an unthinkable novelty. Now, in 2021, we’re getting remarkably close to recreating the process of nuclear fusion here on Earth. Over the last century, scientists have been steadily chasing commercial nuclear fusion, ‘the holy grail of clean energy.’ The first direct demonstration of fusion in a lab took place just 12 years after it was conceptualized, at Cambridge University in 1932, followed by the world’s first attempt to build a fusion reactor in 1938. In 1950, Soviet scientists Andrei Sakharov and Igor Tamm propelled the pursuit forward with their development of the tokamak, a fusion device involving massive magnets which is still at the heart of many major fusion pursuits today, including the world’s biggest nuclear fusion experiment ITER in France.

Since that breakthrough, scientists have been getting closer and closer to achieving nuclear fusion. While fusion has indeed been achieved in labs throughout this timeline, it has always required far more energy than it emits, defeating the purpose of the commercial fusion initiative, and elsewhere in nuclear a new U.S. reactor start-up highlights ongoing progress. If unlocked, commercial nuclear fusion would change life as we know it. It would provide an infinite source of clean energy requiring no fossil fuels and leaving behind no hazardous waste products, and many analysts argue that net-zero emissions may be out of reach without nuclear power, underscoring fusion’s promise.

Nuclear fission, the process which powers all of our nuclear energy production now, including next-gen nuclear designs in development, requires the use of radioactive isotopes to achieve the splitting of atoms, and leaves behind waste products which remain hazardous to human and ecological health for up to tens of thousands of years. Not only does nuclear fusion leave nothing behind, it is many times more powerful. Yet, it has remained elusive despite decades of attempts and considerable investment and collaboration from both public and private entities, such as the Gates-backed mini-reactor concept, around the world.

But just this month there was an incredible breakthrough that may indicate that we are getting close. “For an almost imperceptible fraction of a second on Aug. 8, massive lasers at a government facility in Northern California re-created the power of the sun in a tiny hot spot no wider than a human hair,” CNET reported in August. This breakthrough occurred at the National Ignition Facility, where scientists used lasers to set off a fusion reaction that emitted a stunning 10 quadrillion watts of power. Although the experiment lasted for just 100 trillionths of a second, the amount of energy it produced was equal to about “6% of the total energy of all the sunshine striking Earth’s surface at any given moment.”

“This phenomenal breakthrough brings us tantalizingly close to a demonstration of ‘net energy gain’ from fusion reactions — just when the planet needs it,” said Arthur Turrell, physicist and nuclear fusion expert. What’s more, scientists and experts are hopeful that the rate of fusion breakthroughs will continue to speed up, as interest in atomic energy is heating up again across markets, and commercial nuclear fusion could be achieved sooner than ever seemed possible before. At a time when it has never been more important or more urgent to find a powerful and affordable means of producing clean energy, and as policies like the U.K.’s green industrial revolution guide the next waves of reactors, commercial nuclear fusion can’t come fast enough.

Tesla updates Supercharger billing to add cost of electricity use for other than charging

Tesla Supercharger Billing Update details kWh-based pricing that now includes HVAC, battery thermal management, and other HV loads during charging sessions, improving cost transparency across pay-per-use markets and extreme climate scenarios.

 

Key Points

Tesla's update bills for kWh used by HVAC, battery heating, and HV loads during charging, reflecting true energy costs.

✅ kWh charges now include HVAC and battery thermal management

✅ Expect 10-25 kWh increases in extreme climates during sessions

✅ Some regions still bill per minute due to regulations

 

Tesla has updated its Supercharger billing policy to add the cost of electricity use for things other than charging, like HVAC, battery thermal management, etc, while charging at a Supercharger station, a shift that impacts overall EV charging costs for drivers. 

For a long time, Tesla’s Superchargers were free to use, or rather the use was included in the price of its vehicles. But the automaker has been moving to a pay-to-use model over the last two years in order to finance the growth of the charging network amid the Biden-era charging expansion in the United States.

Not charging owners for the electricity enabled Tesla to wait on developing a payment system for its Supercharger network.

It didn’t need one for the first five years of the network, and now the automaker has been fine-tuning its approach to charge owners for the electricity they consume as part of building better charging networks across markets.

At first, it meant fluctuating prices, and now Tesla is also adjusting how it calculates the total power consumption.

Last weekend, Tesla sent a memo to its staff to inform them that they are updating the calculation used to bill Supercharging sessions in order to take into account all the electricity used:

The calculation used to bill for Supercharging has been updated. Owners will also be billed for kWhs consumed by the car going toward the HVAC system, battery heater, and other HV loads during the session. Previously, owners were only billed for the energy used to charge the battery during the charging session.

Tesla says that the new method should more “accurately reflect the value delivered to the customer and the cost incurred by Tesla,” which mirrors recent moves in its solar and home battery pricing strategy as well.

The automaker says that customers in “extreme climates” could see a difference of 10 to 25 kWh for the energy consumed during a charging session:

Owners may see a noticeable increase in billed kWh if they are using energy-consuming features while charging, e.g., air conditioning, heating etc. This is more likely in extreme climates and could be a 10-25 kWh difference from what a customer experienced previously, as states like California explore grid-stability uses for EVs during peak events.

Of course, this is applicable where Tesla is able to charge by the kWh for charging sessions. In some markets, regulations push Tesla to charge by the minute amid ongoing fights over charging control between utilities and private operators.

Electrek’s Take
It actually looks like an oversight from Tesla in the first place. It’s fair to charge for the total electricity used during a session, and not just what was used to charge your battery pack, since Tesla is paying for both, even as some states add EV ownership fees like the Texas EV fee that further shape costs.

However, I wish Tesla would have a clearer way to break down the charging sessions and their costs.

There have been some complaints about Tesla wrongly billing owners for charging sessions, and this is bound to create more confusion if people see a difference between the kWhs gained during charging and what is shown on the bill.
