Members of rural electric cooperatives in Colorado don't want the state regulating their power supplier.
The Colorado Public Utilities Commission recently heard from co-op members and renewable energy advocates who want state oversight of Tri-State Generation and Transmission Association.
The PUC is considering whether to regulate Tri-State's resource plan, which projects a utility's energy demands and maps out how to meet them. Tri-State submits its plan to the PUC and updates it for information purposes.
Tri-State says it's already governed by federal agencies and the elected boards of the 44 co-ops it serves in four states: Colorado, Wyoming, New Mexico and Nebraska.
Clean-energy advocates say Tri-State relies too heavily on coal and that its decisions affect all Coloradans because of climate change and other environmental effects. They point to Gov. Bill Ritter's emphasis on developing renewable energy, Colorado's efforts to reduce greenhouse gases and state laws requiring utilities to get a certain amount of their power from renewable sources.
"PUC regulation is the best way to encourage the Tri-State system to make investments that are consistent with Colorado energy policy," said Bruce Driver, who represented environmentalists in the forum.
For now, the commission is only gathering information on whether it should regulate Tri-State, which is owned by its member cooperatives.
PUC Commission Chairman Ron Binz said regulators will talk about their next step at a meeting later this year, maybe in mid- to late September. If they decide to try to regulate Tri-State, commissioners would convene a formal rulemaking process.
SaskPower-Flying Dust flare gas power deal advances a 20 MW, 20-year Power Purchase Agreement, enabling grid supply from FNPA-backed generation, supporting renewable strategy, lower carbon footprint targets, and First Nation economic development in Saskatchewan.
Key Points
A 20 MW, 20-year PPA converting flare gas to grid power, with SaskPower buying from Flying Dust First Nation via FNPA.
✅ 20 MW of flare gas generation linked to Saskatchewan's grid
✅ 20-year term; about $300M total value to SaskPower
✅ FNPA-backed project; PPA targeted in 6-12 months
An agreement signed between SaskPower, which reported $205M income in 2019-20, and Flying Dust First Nation is an important step toward a plan that could see the utility buy $300 million worth of electricity from Flying Dust First Nation, according to Flying Dust's chief.
"There's still a lot of groundwork that needs to be done before we get building but you know we're a lot closer today with this signing," Jeremy Norman told reporters Friday.
Norman's community was assisted by the First Nations Power Authority (FNPA), a non-profit that helps First Nations get into the power sector, with examples like the James Bay project showing what Indigenous ownership can achieve.
The agreement signed Friday says SaskPower will explore the possibility of buying 20 megawatts of flare gas power from FNPA, which it will look to Flying Dust to produce.

20-year plan
The proposed deal would span 20 years and cost SaskPower around $300 million over those years, as the utility also explores geothermal power to meet 2030 targets.
The exact price would be determined once a price per metawatt is brought forward.
"We won't be able to do this ourselves," Norman said.
Flare gas power generation works by converting flares from the oil and gas sector into electricity. Under this plan, SaskPower would take the electricity provided by Flying Dust and plug it into the provincial power grid, complementing a recent move to buy more power from Manitoba Hydro to support system reliability.
"This is a great opportunity as we advance our renewable strategy, including progress on doubling renewables by 2030, and try to achieve a lower carbon footprint by 2030 and beyond," Marsh said.

Norman said the business deal presents an opportunity to raise money to reinvest into the First Nation for things like more youth programming.
For the next steps, both parties will need to sign a power purchase agreement that spells out the exact prices for the power generation.
Marsh expects to do so in the next six to 12 months, with development of the required infrastructure to take place after that.
BC Fossil Fuel Phase-Out outlines a just transition to a green economy, meeting climate targets by mid-century through carbon budgets, ending subsidies for fracking, capping production, and investing in renewable energy, remediation, and resilient infrastructure.
Key Points
A strategic plan to wind down oil and gas, end subsidies, and achieve climate targets with a just transition in BC.
✅ End new leases, phase out subsidies, cap fossil production
✅ Carbon budgets and timelines to meet mid-century climate targets
✅ Just transition: income supports, retraining, site remediation jobs
Politicians in British Columbia aren't focused enough on phasing out fossil fuel industries, a new report says.
The report, authored by the left-leaning Canadian Centre for Policy Alternatives, says the province must move away from fossil fuel industries by mid-century in order to meet its climate targets, with B.C. projected to fall short of 2050 targets according to recent analysis, but adds that the B.C. government is ill prepared to transition to a green economy.
"We are totally moving in the wrong direction," said economist Marc Lee, one of the authors of the report, on The Early Edition Wednesday.
He said most of the emphasis of B.C. government policy has been on slowing reductions in emissions from transportation or emissions from buildings, even though Canada will need more electricity to hit net-zero according to the IEA, while still subsidizing fossil fuel extraction, such as fracking projects, that Lee said should be phased out.
"What we are putting on the table is politically unthinkable right now," said Lee, adding that last month's provincial budget called for a 26 per cent increased gas production over the next three years, even though electrified LNG facilities could boost demand for clean power.
B.C.'s $830M in fossil fuel subsidies undermines efforts to fight climate crisis, report says He said B.C. needs to start thinking instead about how its going to wind down its dependence on fossil fuel industries.
'Greener' job transition needed The report said the provincial government's continued interest in expanding production and exporting fossil fuels, even as Canada's race to net-zero intensifies across the energy sector, suggests little political will to think about a plan to move away from them.
It suggests the threat of major job losses in those industries is contributing to the political inaction, but cited several examples of ways governments can help move workers into greener jobs, as many fossil-fuel workers are ready to support the transition according to recent commentary.
Lee said early retirement provisions or income replacement for transitioning workers are options to consider.
"We actually have seen a lot of real-world policy around transition starting to happen, including in Alberta, which brought in a whole transition package for coal workers producing coal for electricity generation, and regional cooperation like bridging the electricity gap between Alberta and B.C. could further support reliability," Lee said.
Give cities the power to move more quickly on the environment, say Metro Van politicians Make it easier for small businesses to go green, B.C. Chamber of Commerce urges government Lee also said well-paying jobs could be created by, for example, remediating old coal mines and gas wells and building green infrastructure and renewable electricity projects in affected areas.
The report also calls for a moratorium on new fossil fuel leases and ending fossil fuel subsidies, as well as creating carbon budgets and fossil fuel production limits.
"Change is coming," said Lee. "We need to get out ahead of it."
ITER Nuclear Fusion advances tokamak magnetic confinement, heating deuterium-tritium plasma with superconducting magnets, targeting net energy gain, tritium breeding, and steam-turbine power, while complementing laser inertial confinement milestones for grid-scale electricity and 2025 startup goals.
Key Points
ITER Nuclear Fusion is a tokamak project confining D-T plasma with magnets to achieve net energy gain and clean power.
✅ Tokamak magnetic confinement with high-temp superconducting coils
✅ Deuterium-tritium fuel cycle with on-site tritium breeding
✅ Targets net energy gain and grid-scale, low-carbon electricity
It sounds like the stuff of dreams: a virtually limitless source of energy that doesn’t produce greenhouse gases or radioactive waste. That’s the promise of nuclear fusion, often described as the holy grail of clean energy by proponents, which for decades has been nothing more than a fantasy due to insurmountable technical challenges. But things are heating up in what has turned into a race to create what amounts to an artificial sun here on Earth, one that can provide power for our kettles, cars and light bulbs.
Today’s nuclear power plants create electricity through nuclear fission, in which atoms are split, with next-gen nuclear power exploring smaller, cheaper, safer designs that remain distinct from fusion. Nuclear fusion however, involves combining atomic nuclei to release energy. It’s the same reaction that’s taking place at the Sun’s core. But overcoming the natural repulsion between atomic nuclei and maintaining the right conditions for fusion to occur isn’t straightforward. And doing so in a way that produces more energy than the reaction consumes has been beyond the grasp of the finest minds in physics for decades.
But perhaps not for much longer. Some major technical challenges have been overcome in the past few years and governments around the world have been pouring money into fusion power research as part of a broader green industrial revolution under way in several regions. There are also over 20 private ventures in the UK, US, Europe, China and Australia vying to be the first to make fusion energy production a reality.
“People are saying, ‘If it really is the ultimate solution, let’s find out whether it works or not,’” says Dr Tim Luce, head of science and operation at the International Thermonuclear Experimental Reactor (ITER), being built in southeast France. ITER is the biggest throw of the fusion dice yet.
Its $22bn (£15.9bn) build cost is being met by the governments of two-thirds of the world’s population, including the EU, the US, China and Russia, at a time when Europe is losing nuclear power and needs energy, and when it’s fired up in 2025 it’ll be the world’s largest fusion reactor. If it works, ITER will transform fusion power from being the stuff of dreams into a viable energy source.
Constructing a nuclear fusion reactor ITER will be a tokamak reactor – thought to be the best hope for fusion power. Inside a tokamak, a gas, often a hydrogen isotope called deuterium, is subjected to intense heat and pressure, forcing electrons out of the atoms. This creates a plasma – a superheated, ionised gas – that has to be contained by intense magnetic fields.
The containment is vital, as no material on Earth could withstand the intense heat (100,000,000°C and above) that the plasma has to reach so that fusion can begin. It’s close to 10 times the heat at the Sun’s core, and temperatures like that are needed in a tokamak because the gravitational pressure within the Sun can’t be recreated.
When atomic nuclei do start to fuse, vast amounts of energy are released. While the experimental reactors currently in operation release that energy as heat, in a fusion reactor power plant, the heat would be used to produce steam that would drive turbines to generate electricity, even as some envision nuclear beyond electricity for industrial heat and fuels.
Tokamaks aren’t the only fusion reactors being tried. Another type of reactor uses lasers to heat and compress a hydrogen fuel to initiate fusion. In August 2021, one such device at the National Ignition Facility, at the Lawrence Livermore National Laboratory in California, generated 1.35 megajoules of energy. This record-breaking figure brings fusion power a step closer to net energy gain, but most hopes are still pinned on tokamak reactors rather than lasers.
In June 2021, China’s Experimental Advanced Superconducting Tokamak (EAST) reactor maintained a plasma for 101 seconds at 120,000,000°C. Before that, the record was 20 seconds. Ultimately, a fusion reactor would need to sustain the plasma indefinitely – or at least for eight-hour ‘pulses’ during periods of peak electricity demand.
A real game-changer for tokamaks has been the magnets used to produce the magnetic field. “We know how to make magnets that generate a very high magnetic field from copper or other kinds of metal, but you would pay a fortune for the electricity. It wouldn’t be a net energy gain from the plant,” says Luce.
One route for nuclear fusion is to use atoms of deuterium and tritium, both isotopes of hydrogen. They fuse under incredible heat and pressure, and the resulting products release energy as heat
The solution is to use high-temperature, superconducting magnets made from superconducting wire, or ‘tape’, that has no electrical resistance. These magnets can create intense magnetic fields and don’t lose energy as heat.
“High temperature superconductivity has been known about for 35 years. But the manufacturing capability to make tape in the lengths that would be required to make a reasonable fusion coil has just recently been developed,” says Luce. One of ITER’s magnets, the central solenoid, will produce a field of 13 tesla – 280,000 times Earth’s magnetic field.
The inner walls of ITER’s vacuum vessel, where the fusion will occur, will be lined with beryllium, a metal that won’t contaminate the plasma much if they touch. At the bottom is the divertor that will keep the temperature inside the reactor under control.
“The heat load on the divertor can be as large as in a rocket nozzle,” says Luce. “Rocket nozzles work because you can get into orbit within minutes and in space it’s really cold.” In a fusion reactor, a divertor would need to withstand this heat indefinitely and at ITER they’ll be testing one made out of tungsten.
Meanwhile, in the US, the National Spherical Torus Experiment – Upgrade (NSTX-U) fusion reactor will be fired up in the autumn of 2022, while efforts in advanced fission such as a mini-reactor design are also progressing. One of its priorities will be to see whether lining the reactor with lithium helps to keep the plasma stable.
Choosing a fuel Instead of just using deuterium as the fusion fuel, ITER will use deuterium mixed with tritium, another hydrogen isotope. The deuterium-tritium blend offers the best chance of getting significantly more power out than is put in. Proponents of fusion power say one reason the technology is safe is that the fuel needs to be constantly fed into the reactor to keep fusion happening, making a runaway reaction impossible.
Deuterium can be extracted from seawater, so there’s a virtually limitless supply of it. But only 20kg of tritium are thought to exist worldwide, so fusion power plants will have to produce it (ITER will develop technology to ‘breed’ tritium). While some radioactive waste will be produced in a fusion plant, it’ll have a lifetime of around 100 years, rather than the thousands of years from fission.
At the time of writing in September, researchers at the Joint European Torus (JET) fusion reactor in Oxfordshire were due to start their deuterium-tritium fusion reactions. “JET will help ITER prepare a choice of machine parameters to optimise the fusion power,” says Dr Joelle Mailloux, one of the scientific programme leaders at JET. These parameters will include finding the best combination of deuterium and tritium, and establishing how the current is increased in the magnets before fusion starts.
The groundwork laid down at JET should accelerate ITER’s efforts to accomplish net energy gain. ITER will produce ‘first plasma’ in December 2025 and be cranked up to full power over the following decade. Its plasma temperature will reach 150,000,000°C and its target is to produce 500 megawatts of fusion power for every 50 megawatts of input heating power.
“If ITER is successful, it’ll eliminate most, if not all, doubts about the science and liberate money for technology development,” says Luce. That technology development will be demonstration fusion power plants that actually produce electricity, where advanced reactors can build on decades of expertise. “ITER is opening the door and saying, yeah, this works – the science is there.”
Raindrop Triboelectric Energy Harvesting converts falling water into electricity using Teflon (PTFE) on indium tin oxide and an aluminum electrode, forming a transient water bridge; a low frequency nanogenerator for renewable, static electricity harvesting.
Key Points
A method using PTFE, ITO, and an aluminum electrode to turn raindrop impacts into low frequency electrical power.
✅ PTFE on ITO boosts charge transfer efficiency.
✅ Water bridge links electrodes for rapid discharge.
✅ Low frequency output suits continuous energy harvesting.
Scientists at the City University of Hong Kong have used a Teflon-coated surface and a phenomenon called triboelectricity to generate a charge from raindrops. “Here we develop a device to harvest energy from impinging water droplets by using an architecture that comprises a polytetrafluoroethylene [Teflon] film on an indium tin oxide substrate plus an aluminium electrode,” they explain in their new paper in Nature as a step toward cheap, abundant electricity in the long term.
Triboelectricity itself is an old concept. The word means “friction electricity”—from the Greek tribo, to rub or wear down, which is why a diatribe tires you out—and dates back a long, long time. Static electricity is the most famous kind of triboelectric, and related work has shown electricity from the night sky can be harvested as well in niche setups. In most naturally occurring kinds, scientists have studied triboelectric in order to avoid its effects, like explosions inside of grain silos or hospital workers touching off pure oxygen. (Blowing sand causes an electric field, and NASA even worries about static when astronauts eventually land on Mars.)
One of the most studied forms of intentional and useful triboelectric is in systems such as ocean wave generators where the natural friction of waves meets nanogenerators of triboelectric energy. These even already use Teflon, which has natural conductivity that makes it ideal for this job. But triboelectricity is chaotic, and harnessing it generally involves a bunch of complicated, intersecting variables that can vary with the hourly weather. Promises of static electricity charging devices have often been, well, so much hot, sandy wind.
The scientists at City University of Hong Kong used triboelectric ideas to turn falling raindrops into energy. They say previous versions of the same idea were not very efficient, with materials that didn’t allow for high-fidelity transfer of electrical charge. (Many sources of renewable energy aren’t yet as efficient to turn into power, both because of developing technology and because their renewability means even less efficient use could be better than, for example, fossil fuels, and advances in renewable energy storage could help.)
“[A]chieving a high density of electrical power generation is challenging,” the team explains in its paper. “Traditional hydraulic power generation mainly uses electromagnetic generators that are heavy, bulky, and become inefficient with low water supply.” Diversifying how power is generated by water sources such as oceans and rivers is good for the existing infrastructure as well as new installations.
The research team found that as simulated raindrops fell on their device, the way the water accumulated and spread created a link between their two electrodes, one Teflon-coated and the other aluminum. This watery de facto wire link closes the loop and allows accumulated energy to move through the system. Because it’s a mechanical setup, it’s not limited to salty seawater, and because the medium is already water, its potential isn’t affected by ambient humidity either.
Raindrop energy is very low frequency, which means this tech joins many other existing pushes to harvest continuously available, low frequency natural energy, including underwater 'kites' that exploit steady currents. To make an interface that increases “instantaneous power density by several orders of magnitude over equivalent devices,” as the researchers say they’ve done here, could represent a major step toward feasibility in triboelectric generation.
Ireland Coal-Free Electricity Record: EirGrid reports 25 days without coal on the all-island grid, as wind power, renewables, and natural gas dominated generation, cutting CO2 emissions, with Moneypoint sidelined by market competitiveness.
Key Points
It is a 25-day period when the grid used no coal, relying on gas and renewables to reduce CO2 emissions.
✅ 25 days coal-free between April 11 and May 7
✅ Gas 60%, renewables 30% of generation mix
✅ Eurostat: 6.8% drop in Ireland's CO2 emissions
The island of Ireland has gone a record length of time without using coal-fired electricity generation on its power system, Britain's week-long coal-free run providing a recent comparator, Eirgrid has confirmed.
The all-island grid operated without coal between April 11th and May 7th – a total of 25 days, it confirmed. This is the longest period of time the grid has operated without coal since the all-island electricity market was introduced in 2007, echoing Britain's record coal-free stretch seen recently.
Ireland’s largest generating station, Moneypoint in Co Clare, uses coal, with recent price spikes in Ireland fueling concerns about dispatchable capacity, as do some of the larger generation sites in Northern Ireland.
The analysis coincides with the European statistics agency, Eurostat publishing figures showing annual CO2 emissions in Ireland fell by 6.8 per cent last year; partly due to technical problems at Moneypoint.
Over the 25-day period, gas made up 60 per cent of the fuel mix, while renewable energy, mainly wind, accounted for 30 per cent, echoing UK wind surpassing coal in 2016 across the market. Coal-fired generation was available during this period but was not as competitive as other methods.
EirGrid group chief executive Mark Foley said this was “a really positive development” as coal was the most carbon intense of all electricity sources, with its share hitting record lows in the UK in recent years.
“We are acutely aware of the challenges facing the island in terms of meeting our greenhouse gas emission targets, mindful that low-carbon generation stalled in the UK in 2019, through the deployment of more renewable energy on the grid,” he added.
Last year 33 per cent of the island’s electricity came from renewable energy sources, German renewables surpassing coal and nuclear offering a parallel milestone, a new record. Coal accounted for 9 per cent of electricity generation, down from 12.9 per cent in 2017.
Alberta Coal Community Transition Fund backs renewables, natural gas, and economic diversification, offering grants, workforce retraining, and community development to municipalities and First Nations as Alberta phases out coal-fired power by 2030.
Key Points
A provincial grant helping coal-impacted communities diversify, retrain workers, and transition to renewables by 2030.
✅ Grants for municipalities and First Nations
✅ Supports diversification and job retraining
✅ Focus on renewables, natural gas, and new sectors
The Coal Community Transition Fund is open to municipalities and First Nations affected as Alberta phases out coal-fired electricity by 2030 under the federal coal plan to focus on renewables and natural gas.
Economic Development Minister Deron Bilous says the government wants to ensure these communities thrive through the transition, aligning with views that fossil-fuel workers support the energy transition across the economy.
“Residents in our communities have concerns about the transition away from coal, even as discussions about phasing out fossil fuels in B.C. unfold nationally,” Rod Shaigec, mayor of Parkland County, said.
“They also have ideas on how we can mitigate the impacts on workers and diversify our economy, including clean energy partnerships to create new employment opportunities for affected workers. We are working to address those concerns and support their ideas. This funding means we can make those ideas a reality in various economic sectors of opportunity.”
The coal-mining town of Hanna, northeast of Calgary, has already received $450,000 through the program to work on economic diversification, exploring options like bridging the Alberta-B.C. electricity gap that could support new industries.
The application deadline for the coal transition fund is the end of November.
A provincial advisory panel is also expected to report back this fall on ways to create new jobs and retrain workers during the coal phase-out.
