TVA, which has an increased emphasis on clean energy, renewable energy and energy efficiency, has two contracts for renewable energy with Waste Management in Tennessee.
TVA has just signed a 20-year contract with Waste Management to buy 4.8 megawatts of power from a landfill-biogas facility at Camden in West Tennessee. That contract is the first in TVA's new renewable standard offer initiative.
TVA pays a set price — or a "standard offer" — for renewable power based on the time of day the electricity is available to the TVA power grid. TVA's Renewable Standard Offer initially will be limited to a total of 100 megawatts from all participants, with no single renewable technology representing more than 50 megawatts of the total.
The Chestnut Ridge facility along the Knox-Anderson county line has been providing electricity for about 1,600 homes that are KUB customers. TVA and Waste Management have been partners in the Chestnut Ridge power contract for nearly 20 years.
TVA also buys power — 3 megawatts — from methane facilities at Middle Point Landfill in Murfreesboro, Tenn., and 8 megawatts from the city of Memphis wastewater treatment plant.
TVA spokesman Mike Bradley said the agency does not discuss pricing for the renewable energy contracts, citing the information as "business sensitive."
TVA, which also gets renewable energy from wind, solar and biomass and customers, has an agreement with the state of Tennessee to buy up to 5 megawatts of electricity from a solar farm being built in Haywood County in West Tennessee. The University of Tennessee and the state are developing that facility.
The agency has added 1,625 megawatts of wind energy — 300 megawatts from an Illinois company and 29 megawatts from the Buffalo Mountain turbines near Oliver Springs.
TVA's Generation Partners program — for very small power producers — includes more than 560 participants that produce about 65 megawatts of power from solar biomass, wind and low-impact hydro generation.
Sustainable Marine tidal energy delivers in-stream power to Nova Scotia's grid from Grand Passage, proving low-impact, renewable generation and advancing a floating tidal array at FORCE and Minas Passage in the Bay of Fundy.
Key Points
The first in-stream tidal project supplying clean power to Nova Scotia's grid, proven at Grand Passage.
✅ First to deliver in-stream tidal power to Canada's grid
✅ Demonstration at Grand Passage informs FORCE deployments
✅ Low-impact design and environmental monitoring validated
Sustainable Marine has officially powered up its tidal energy operation in Canada and is delivering clean electricity to the power system in Nova Scotia, on the country’s Atlantic coast, as the province moves to increase wind and solar projects in the years ahead. The company’s system in Grand Passage is the first to deliver in-stream tidal power to the grid in Canada, following provincial approval to harness Bay of Fundy tides that is spurring further development.
The system start-up is the culmination of more than a decade of research, development and testing, including lessons from Scottish tidal projects in recent years and a powerful tidal turbine feeding onshore grids, managing the technical challenges associated with operating in highly energetic environments and proving the ultra-low environmental impact of the tidal technology.
Sustainable Marine is striving to deliver the world’s first floating tidal array at FORCE (Fundy Ocean Research Centre for Energy). This project will be delivered in phases, drawing upon the knowledge gained and lessons learned in Grand Passage, and insights from offshore wind pilots like France’s first offshore wind turbine in Europe. In the coming months the company will continue to operate the platform at its demonstration site at Grand Passage, gradually building up power production, while New York and New England clean energy demand continues to rise, to further prove the technology and environmental monitoring systems, before commencing deployments in the Minas Passage – renowned as the Everest of tidal energy.
The Bay of Fundy’s huge tidal energy resource contains more than four times the combined flow of every freshwater river in the world, with the potential to generate approximately 2,500 MW of green energy, underscoring why independent electricity planning will be important for integrating marine renewables.
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.”
Toronto Hydro Scam Warning urges customers to spot phishing emails, fraudulent texts, fake bills, and door-to-door threats demanding bitcoin or prepaid cards, with disconnection threats; report scams to the Canadian Anti-Fraud Centre.
Key Points
Advisory on phishing, fake bills, and payment scams posing as Toronto Hydro, with steps to avoid fraud and report.
✅ Hang up suspicious calls; never pay via bitcoin or prepaid cards.
✅ Do not click links in emails or texts; compare bills and account numbers.
✅ Report fraud to the Canadian Anti-Fraud Centre: 1-888-495-8501.
Toronto Hydro has sent out a notice that criminals posing as Toronto Hydro are sending out fraudulent texts, letters and emails, similar to a recent BC Hydro scam reported in British Columbia.
The warning comes in a tweet, along with suggestions on how to protect yourself from fraud, especially as policy debates like an NDP public hydro plan can generate confusing messages.
According to Toronto Hydro, fraudsters are contacting people by phone, text, email, fake electricity bills, and even travelling door-to-door.
They threaten to disconnect the power unless an immediate payment is made, even though legitimate utilities must follow proper disconnection notices processes. The website states that in some cases, criminals request payment via pre-paid credit card or bitcoin.
It’s written on the website that Toronto Hydro does not accept these methods of payment, and they do not threaten to immediately disconnect power, a reminder that stories about power theft abroad are not a model for local billing.
If you suspect you are being targeted, you should immediately hang up any suspicious phone calls. Don’t click on any links in emails or texts asking you to accept electronic transfers, as scammers may impersonate well-known utilities during high-profile news such as Hydro One profit changes to appear credible.
Avoid sharing any personal information over the phone or in-person, and do not make any payments related to Smart Meter Deposits, as this fee does not exist and rate-setting is overseen by the Ontario Energy Board in Ontario.
And remember to always compare bills to previous ones, including the amount and account number, since major accounting decisions like a BC Hydro deferral report can fuel confusing narratives.

Ontario electricity pricing consultations will gather business input on OEB rate design, Industrial Conservation Initiative, dynamic pricing, global adjustment, and system costs through online feedback and sector-specific in-person sessions province-wide.
Key Points
Consultations gathering business input on rates, programs, and OEB policy to improve fairness and reduce system costs.
✅ Consults on ICI, GA, dynamic pricing structures
✅ Seeks views on OEB C&I rate design changes
✅ In-person sessions across key industrial sectors
The Ontario government has announced plans to hold consultations to seek input from businesses about industrial electricity pricing and programs. This will be done through Ontario's online consultations directory and though in-person sector-specific consultation sessions across the province. The in-person sessions will be held in all areas of Ontario, and will target "key industries," including automotive and the build-out of electric vehicle charging stations infrastructure, forestry, mining, agriculture, steel, manufacturing and chemicals.
On April 1, 2019, the Ontario government published a consultation notice for this process, confirming that it is looking for input on "electricity rate design, existing tax-based incentives, reducing system costs and regulatory and delivery costs," including related proposals such as the hydrogen rate reduction proposal under discussion. The consultation process includes a list of nine questions for respondents (and presumably participants in the in-person sessions) to address. These include questions about:
The benefits of the Industrial Conservation Initiative (described below), including how it could be changed to improve fairness and industrial competitiveness, and how it could complement programs like the Hydrogen Innovation Fund that support industrial innovation.
Dynamic pricing structures that allow for lower rates in return for responding to price signals versus a flat rate structure that potentially costs more, but is more stable and predictable, as Ontario's energy storage expansion accelerates.
Interest in an all-in commodity contract with an electricity retailer, even if it involves a risk premium.
Interested parties are invited to submit their comments before May 31, 2019.
The government's consultation announcement follows recent developments in the Ontario Energy Board's (OEB) review of electricity ratemaking for commercial and industrial customers, and intertie projects such as the Lake Erie Connector that could affect market dynamics.
In December 2018, the OEB published a paper from its Market Surveillance Panel (MSP) examining the Industrial Conservation Initiative (ICI), and potential alternative approaches. The ICI is a program that allows qualifying large industrial customers to base their global adjustment (GA) payments on their consumption during five peak demand hours in a year. Customers who find ways to reduce consumption at those times, perhaps through DERs and enabling energy storage options, will reduce their electricity costs. This shifts GA costs to other customers. The MSP found that the ICI does not fairly allocate costs to those who cause them and/or benefit from them, and recommends that a better approach should be developed.
In February 2019, the OEB released its Staff Report to the Board on Rate Design for Commercial and Industrial Electricity Customers, setting out recommendations for new rate designs for electricity commercial and industrial (C&I) rate classes as Ontario increasingly turns to battery storage to meet rising demand. As described in an earlier post, the Staff Report includes recommendations to: (i) establish a fixed distribution charge for commercial customers with demands under 10 kW; (ii) implement a demand charge (rather than the current volumetric charge) for C&I customers with demands between 10kW and 50kW; and (iii) introduce a "capacity reserve charge" for customers with load displacement generation to replace stand-by charges and provide for recognition of the benefits of this generation on the system. The OEB held a stakeholder information session in mid-March on this initiative, and interested parties are now filing submissions in response to the Staff Report.
Whether and how the OEB's processes will fit together with the government's consultation process remains to be seen.
Puerto Rico Earthquakes continue as a seismic swarm with aftershocks, landslides near Pe f1uelas, damage in Ponce and Guayanilla, grid outages from Costa Sur Plant, PREPA recovery, vulnerable buildings post-Hurricane Maria raising safety concerns.
Key Points
Recurring seismic events impacting Puerto Rico, causing damage, aftershocks, outages, and displacement.
✅ Seismic swarm with 6.4 and 5.9 magnitude quakes and ongoing aftershocks
✅ Costa Sur Plant offline; PREPA urges conservation amid grid repairs
✅ Older, code-deficient buildings and landslides raise safety risks
Some in Puerto Rico are beginning to fear the ground will never stop shaking. The island has been pummeled by hundreds of earthquakes in recent weeks, including the recent 5.9 magnitude temblor, where there were reports of landslides in the town of Peñuelas along the southern coast, rattling residents already on edge from the massive 6.4 magnitude quake, and raising wider concerns about climate risks to the grid in disaster-prone regions.
That was the largest to strike the island in more than a century causing hundreds of structures to crumble, forcing thousands from their homes and leaving millions without power, a scenario echoed by Texas power outages during winter storms too. One person was killed and several others injured.
Utility says 99% of customers have electricity
Puerto Rico's public utility, PREPA, tweeted some welcome news Monday: that nearly all of the homes and businesses it serves have had electric power restored. Still it is urging customers to conserve energy amid utility supply-chain shortages that can slow critical repairs.
Reporting from the port city of Ponce, NPR's Adrian Florido said the Costa Sur Plant, which produces more than 40% of Puerto Rico's electricity, was badly damaged in last week's quake. It remains offline indefinitely, even as grid operators elsewhere have faced California blackout warnings during extreme heat.
He also reports many residents are still reeling from the devastation caused by Hurricane Maria, a deadly Category 4 storm that battered the island in September 2017. The storm exposed the fact that buildings across the island were not up to code, similar to how aging systems have contributed to PG&E power line fires in California. The series of earthquakes are only amplifying fears that structures have been further weakened.
"People aren't coping terribly well," Florido said on NPR's Morning Edition Monday, noting that households elsewhere have endured pandemic power shutoffs and burdensome bills.
Many earthquake victims sleeping outdoors
Florido spoke to one displaced resident, Leticia Espada, who said more than 50 homes in her town of Guayanilla, about an hour drive east of the port city of Ponce, had collapsed.
After sleeping outside for days on her patio following Tuesday's quake, she eventually came to her town's baseball stadium where she's been sleeping on one of hundreds of government-issued cots.
She's like so many others sleeping in open-air shelters, many unwilling to go back to their homes until they've been deemed safe, while even far from disaster zones, brief events like a Northeast D.C. outage show how fragile service can be.
"Thousands of people across several towns sleeping in tents or under tarps, or out in the open, protected by nothing but the shade of a tree with no sense of when these quakes are going to stop," Florido reports.
Trump NEPA Overhaul streamlines environmental reviews, tightening 'reasonably foreseeable' effects, curbing cumulative impacts, codifying CEQ greenhouse gas guidance, expediting permits for pipelines, highways, and wind projects with two-year EIS limits and one lead agency.
✅ Limits cumulative and indirect impacts; emphasizes foreseeable effects
✅ Caps EIS at two years; one-year environmental assessments
✅ One lead agency; narrower NEPA triggers for low federal funding
President Trump has announced plans for overhauling rules surrounding the nation’s bedrock environmental law, and administration officials refuted claims they were downplaying greenhouse gas emissions, as the administration also pursues replacement power plant rules in related areas.
The president, during remarks at the White House with supporters and Cabinet officials, said he wanted to fix the nation’s “regulatory nightmare” through new guidelines for implementing the National Environmental Policy Act.
“America is a nation of builders,” he said. But it takes too long to get a permit, and that’s “big government at its absolute worst.”
The president said, “We’re maintaining America’s world-class standards of environmental protection.” He added, “We’re going to have very strong regulation, but it’s going to go very quickly.”
NEPA says the federal government must consider alternatives to major projects like oil pipelines, highways and bridges that could inflict environmental harm. The law also gives communities input.
The Council on Environmental Quality has not updated the implementing rules in decades, and both energy companies and environmentalists want them reworked, even as some industry groups warned against rushing electricity pricing changes under related policy debates.
But they patently disagree on how to change the rules.
A central fight surrounds whether the government considers climate change concerns when analyzing a project.
Environmentalists want agencies to look more at “cumulative” or “indirect” impacts of projects. The Trump plan shuts the door on that.
“Analysis of cumulative effects is not required,” the plan states, adding that CEQ “proposes to make amendments to simplify the definition of effects by consolidating the definition into a single paragraph.”
CEQ Chairwoman Mary Neumayr told reporters during a conference call that definitions in the current rules were the “subject of confusion.”
The proposed changes, she said, do in fact eliminate the terms “cumulative” and “indirect,” in favor of more simplified language.
Effects must be “reasonably foreseeable” and require a “reasonably close causal relationship” to the proposed action, she added. “It does not exclude considerations of greenhouse gas emissions,” she said, pointing to parallel EPA proposals for new pollution limits on coal and gas power plants as context.
Last summer, CEQ issued proposed guidance on greenhouse gas reviews in project permitting. The nonbinding document gave agencies broad authority when considering emissions (Greenwire, June 21, 2019).
Environmentalists scoffed and said the proposed guidance failed to incorporate the latest climate science and look at how projects could be more resilient in the face of severe weather and sea-level rise.
The proposed NEPA rules released today include provisions to codify the proposed guidance, which has also been years in the making.
Other provisions
Senior administration officials sought to downplay the effect of the proposed NEPA rules by noting the underlying statute will remain the same.
“If it required NEPA yesterday, it will require NEPA under the new proposal,” an official said when asked how the changes might apply to pipelines like Keystone XL.
And yet the proposed changes could alter the “threshold consideration” that triggers NEPA review. The proposal would exclude projects with minimal federal funding or “participation.”
The Trump plan also proposes restricting an environmental impact statement to two years and an environmental assessment to one.
Neumayr said the average EIS takes 4 ½ years and in some cases longer. Democrats have disputed those timelines. Further, just 1% of all federal actions require an EIS, they argue.
The proposal would also require one agency to take the lead on permitting and require agency officials to “timely resolve disputes that may result in delays.”
In general, the plan calls for environmental documents to be “concise” and “serve their purpose of informing decision makers.”
Both Interior Secretary David Bernhardt and EPA Administrator Andrew Wheeler, whose agency moved to rewrite coal power plant wastewater limits in separate actions, were at the White House for the announcement.
Reaction
An onslaught of critics have said changes to NEPA rules could be the administration’s most far-reaching environmental rollback, and state attorneys general have mounted a legal challenge to related energy actions as well.
The League of Conservation Voters declared the administration was again trying to “sell out the health and well-being of our children and families to corporate polluters.”
On Capitol Hill, House Speaker Nancy Pelosi (D-Calif.) said during a news conference the administration would “no longer enforce NEPA.”
“This means more polluters will be right there, next to the water supply of our children,” she said. “That’s a public health issue. Their denial of climate, they are going to not use the climate issue as anything to do with environmental decisionmaking.”
Sen. Sheldon Whitehouse (D-R.I.) echoed the sentiment, saying he didn’t need any more proof that the fossil fuel industry had hardwired the Trump administration “but we got it anyway.”
Energy companies, including firms focused on renewable energy development, are welcoming the “clarity” of the proposed NEPA rules, even as debates continue over a clean electricity standard in federal climate policy.
“The lack of clarity in the existing NEPA regulations has led courts to fill the gaps, spurring costly litigation across the sector, and has led to unclear expectations, which has caused significant and unnecessary delays for infrastructure projects across the country,” the Interstate Natural Gas Association of America said in a statement.
Last night, the American Wind Energy Association said NEPA rules have caused “unreasonable and unnecessary costs and long project delays” for land-based and offshore wind energy and transmission development.
Trump has famously attacked the wind energy industry for decades, dating back to his opposition to a Scottish wind turbine near his golf course.
The president today said he won’t stop until “gleaming new infrastructure has made America the envy of the world again.”
When asked whether he thought climate change was a “hoax,” as he once tweeted, he said no. “Nothing’s a hoax about that,” he said.
The president said there’s a book about climate he’s planning to read. He said, “It’s a very serious subject.”
