New material makes electricity from waste heat

UK Energy Price Guarantee Cost forecasts from Cornwall Insight suggest an £89bn bill, tied to wholesale gas prices, OBR projections, and fiscal policy, to shield households amid the cost of living crisis.

Key Points

It is the projected government spend to cap household bills, driven by wholesale gas prices and OBR market forecasts.

✅ Base case: £89bn over two years, per Cornwall Insight

✅ Range: £72bn to £140bn, volatile wholesale gas costs

✅ Excludes 6-month business support estimated at £22bn-£48bn

Liz Truss’s intervention to freeze energy prices for households for two years is expected to cost the government £89bn, according to the first major costing of the policy by the sector’s leading consultancy.

The analysis from Cornwall Insight, seen exclusively by the Guardian, shows the prime minister’s plan to tackle the cost of living crisis could cost as much as £140bn in a worst-case scenario.

Truss announced in early September that the average annual bill for a typical household would be capped at £2,500 to protect consumers from the intensifying cost of living crisis amid high winter energy costs and a scheduled 80% rise in the cap to £3,549.

The ultimate cost of the policy is uncertain as it is highly dependent on the wholesale cost of gas, including UK natural gas prices which have soared since Russia’s invasion of Ukraine put a squeeze on already-volatile international markets. Ballpark projections had put the cost anywhere from £100bn to £150bn.

The Office for Budget Responsibility is expected to give its forecast for the bill when it provides its independent assessment of Kwasi Kwarteng’s medium-term fiscal plan, which the chancellor said on Tuesday would still happen on 23 November despite previous reports that it would be brought forward.

Cornwall Insight analysed projections of wholesale market moves to cost the intervention. In its base case scenario, analysts expect the policy to cost £89bn. That assumes the cost of supporting each household would be just over £1,000 in the first year, and about £2,000 in the second year.

The study’s authors said the wholesale price of gas would be influenced by energy demand, the severity of weather, “geo-political uncertainty” and prices for liquified natural gas as Europe seeks to refill storage facilities, which countries have rushed to fill up this winter but which could be relatively empty by next spring.

In the best-case outcome, the policy would cost £72bn, with some projections pointing to a 16% decrease in energy bills in April for households, while the “extreme high” outlook would see the government shell out £140bn to protect 29m UK households.

Gas prices are expected to push even higher if the Kremlin decides to completely cut off Russian gas exports into Europe.

Cornwall Insight’s projection does not include a separate six-month initiative to cap costs for companies, charities and public sector organisations, which is forecast to cost £22bn to £48bn.

The consultancy’s chief executive, Gareth Miller, said the £70bn range in its forecasts reflected “a febrile wholesale market continuing to be beset by geopolitical instability, sensitivity to demand, weather and infrastructure resilience”.

He said: “Fortune befriends the bold, but it also favours the prepared. The large uncertainties around commodity markets over the next two years means that the government could get lucky with costs coming out at the low end of the range, but the opposite could also be true.

“In each case, the government may find itself passengers to circumstances outside its control, having made policy that is a hostage to surprises, events and volatile factors. That’s a difficult position to be in.”

The government has faced criticism, as some British MPs urge tighter limits on prices, that the policy is effectively a “blank cheque” and is not targeted at the most vulnerable in society.

Concerns over how Truss and Kwarteng intend to fund a series of measures, including the price guarantee, have spooked financial markets.

The EU, which has outlined possible gas price cap strategies in recent proposals, said last week it planned to cap the revenues of low-carbon electricity generators at €180 a megawatt hour, which is less than half current market prices. Truss has so far resisted calls to extend a levy on North Sea oil and gas operators to electricity generators, who have benefited from a link between gas and electricity prices in Britain.

Truss hopes to strike voluntary long-term deals with generators including Centrica and EDF, alongside the government’s Energy Security Bill measures, to bring down wholesale prices.

The Financial Times reported on Tuesday that the government has threatened companies with legislation to cap their revenues if voluntary deals cannot be agreed.

Pinghai Bay Offshore Wind Farm MWS advances marine warranty survey best practices, risk management, and international standards in Fujian, with Haixia Goldenbridge Insurance and reinsurer-aligned audits supporting safer offshore wind construction and logistics.

Key Points

An MWS program ensuring Pinghai Bay Phase 2 meets standards via audits, risk controls, and vetted procedures.

✅ First MWS delivered in China's offshore wind market

✅ Audits, risk consultancy, and reinsurer-aligned standards

✅ Supports 250MW Phase 2 at Pinghai Bay, Fujian

LOC Renewables has announced it is to carry out marine warranty survey (MWS) services for the second phase of the Pinghai Bay Offshore Wind Farm near Putian, Fujian province, China, on behalf of Haixia Goldenbridge Insurance Co., Ltd. The agreement represents the first time MWS services have been delivered to the Chinese offshore wind market.

China’s installed offshore capacity jumped more than 60% in 2017, and its growing offshore market is aiming for a total grid-connected capacity of 5GW by 2020, as the sector globally advances toward a $1 trillion industry over the coming decades. Much of this future offshore development is slated to take place in Jiangsu, Zhejiang, Guangdong and Fujian provinces. As developers becoming increasingly aware of the need for stringent risk management and value that internationally accepted standards can bring to projects, Pinghai Bay will be the first Chinese offshore wind farm to employ MWS to ensure it meets the highest technical standards and minimise project risk. The agreement will see LOC Renewables carry out audit and risk consultancy services for the project from March until the end of 2018.

In recent years, as Chinese offshore wind projects have grown in scale and complexity the need for international expertise in the market has increased, with World Bank support for emerging markets underscoring global momentum. In response, domestic insurers are partnering with international reinsurers to manage and mitigate the associated larger risks. Applying the higher standards required by international reinsurers, LOC Renewables will draw on its extensive experience in European, US and Asian offshore wind markets to provide MWS services on the Pinghai project from its Tianjin office.

“As offshore wind technology continues to proliferate across Asia, driven by declining global costs, successful knowledge transfer based on best practices and lessons learned in the established offshore wind markets becomes ever more important,” said Ke Wan, Managing Director, LOC China.

“With a wealth of experience in Europe and the US, where UK offshore wind growth has accelerated, we’re increasingly working on projects across Asia, and are delighted to now be providing the first MWS services to China’s offshore wind market – services that bring real value in lower risk and will enable the project to achieve its full potential.”

“At 250MW, phase two of the Pinghai Bay Wind Farm represents a significant expansion on phase one, and we wanted to ensure that it met the highest technical and risk mitigation standards, informed by regional learnings such as Korean installation vessels analyses,” said Fan Ming, Business Director at Haixia Goldenbridge Insurance.

“In addition to their global experience, LOC Renewables’ familiarity with and presence in the local market was very important to us, and we’re looking forward to working closely with them to help bring this project to fruition and make a significant contribution to China’s expanding offshore wind market.”

Mercury Energy Tilt Renewables acquisition signals a trans-Tasman energy push as PowAR and Mercury split assets via a scheme of arrangement, offering $7.80 per share and a $2.96b valuation across Australia and New Zealand.

Key Points

A PowAR-Mercury deal to buy Tilt Renewables, splitting Australian and New Zealand assets via a court-approved scheme.

✅ $7.80 per share, valuing Tilt at $2.96b

✅ PowAR takes AU assets; Mercury gets NZ business

✅ Infratil and Mercury to vote for the scheme

Mercury Energy and an Australian partner appear to have won the race to buy Tilt Renewables, an Australasian wind farm developer which was spun out of TrustPower, bidding almost $3 billion, amid wider utility consolidation such as the Peterborough Distribution sale to Hydro One.

Yesterday Tilt Renewables announced that it had entered a scheme implementation agreement under which it was proposed that PowAR would acquire its Australian business and Mercury would acquire the New Zealand business, mirroring cross-border approvals where U.S. antitrust clearance shaped Hydro One's bid for Avista.

Conducted through a scheme of arrangement, Tilt shareholders will be offered $7.80 a share, valuing Tilt at $2.96b.

Yesterday morning shares in Tilt opened about 18 per cent up at $7.65, though regulatory outcomes can swing valuations as seen when Hydro One-Avista reconsideration of a U.S. order came into play.

In early December Infratil, which owns around two thirds of Tilt's shares, announced it was undertaking a review of its investment after receiving approaches, with investor sentiment sensitive to governance shifts as when Hydro One shares fell after leadership changes in Ontario.

According to a report in the Australian Financial Review, the transtasman bid beat out other parties including ASX-listed APA Group, Canadian pension fund CDPQ and Australian fund manager Infrastructure Capital Group, as Canadian investors like Ontario Teachers' Plan pursue similar infrastructure deals.

“This compelling acquisition proposal is a result of Tilt Renewables’ constant focus on delivering long-term value for shareholders and the board is pleased that, with these new owners, the transition to renewables in Australia and New Zealand will continue to accelerate,” Tilt’s chairman Bruce Harker said.

Comparable community-led clean energy partnerships, such as initiatives with British Columbia First Nations highlighted in clean-energy generation, underscore the broader momentum.

Just prior to the announcement, Tilt shares had been trading for less than $4. Such repricing reflects how utilities can face perceived uncertainties, as one investor argued too many unknowns at the time.

Mercury is already Tilt’s second largest shareholder, at just under 20 per cent. Both Infratil and Mercury have agreed to vote in favour of the scheme. The deal values Tilt’s New Zealand business at $770m, however the value of Mercury’s existing shareholding is around $585m, meaning the company will increase debt by around $185m.

Cement-Based Conductive Composite transforms concrete into power by energy harvesting via triboelectric nanogenerator action, carbon fibers, and built-in capacitors, enabling net-zero buildings and self-sensing structural health monitoring from footsteps, wind, rain, and waves.

Key Points

A carbon fiber cement that harvests and stores energy as electricity, enabling net-zero, self-sensing concrete.

✅ Uses carbon fibers to create a conductive concrete matrix

✅ Acts as a triboelectric nanogenerator and capacitor

✅ Enables net-zero, self-sensing structural health monitoring

Engineers from South Korea have invented a cement-based composite that can be used in concrete to make structures that generate and store electricity through exposure to external mechanical energy sources like footsteps, wind, rain and waves, and even self-powering roads concepts.

By turning structures into power sources, the cement will crack the problem of the built environment consuming 40% of the world’s energy, complementing vehicle-to-building energy strategies across the sector, they believe.

Building users need not worry about getting electrocuted. Tests showed that a 1% volume of conductive carbon fibres in a cement mixture was enough to give the cement the desired electrical properties without compromising structural performance, complementing grid-scale vanadium flow batteries in the broader storage landscape, and the current generated was far lower than the maximum allowable level for the human body.

Researchers in mechanical and civil engineering from from Incheon National University, Kyung Hee University and Korea University developed a cement-based conductive composite (CBC) with carbon fibres that can also act as a triboelectric nanogenerator (TENG), a type of mechanical energy harvester.

They designed a lab-scale structure and a CBC-based capacitor using the developed material to test its energy harvesting and storage capabilities, similar in ambition to gravity storage approaches being scaled.

“We wanted to develop a structural energy material that could be used to build net-zero energy structures that use and produce their own electricity,” said Seung-Jung Lee, a professor in Incheon National University’s Department of Civil and Environmental Engineering, noting parallels with low-income housing microgrids in urban settings.

“Since cement is an indispensable construction material, we decided to use it with conductive fillers as the core conductive element for our CBC-TENG system,” he added.

The results of their research were published this month in the journal Nano Energy.

Apart from energy storage and harvesting, the material could also be used to design self-sensing systems that monitor the structural health and predict the remaining service life of concrete structures without any external power, which is valuable in industrial settings where hydrogen-powered port equipment is being deployed.

“Our ultimate goal was to develop materials that made the lives of people better and did not need any extra energy to save the planet. And we expect that the findings from this study can be used to expand the applicability of CBC as an all-in-one energy material for net-zero energy structures,” said Prof. Lee, pointing to emerging circular battery recycling pathways for net-zero supply chains.

Publicising the research, Incheon National University quipped: “Seems like a jolting start to a brighter and greener tomorrow!”

Ontario Global Adjustment Appeal spotlights Ontario's electricity fee, regulatory charge vs tax debate, FIT contracts, green energy policy, and constitutional challenge as National Steel Car contests soaring power costs before the Ontario Superior Court.

Key Points

Court challenge over Ontario's global adjustment fee, disputing its status as a regulatory charge instead of a tax.

✅ Challenges classification of global adjustment as tax vs regulatory charge.

✅ Focuses on FIT contracts, renewable energy payments, power cost impacts.

✅ Appeals Ontario ruling; implications for ratepayers and policy.

A manufacturer of steel rail cars is pursuing an appeal after its lawsuit challenging the constitutionality of a major Ontario electricity fee was struck down earlier this year.

Lawyers for Hamilton, Ont.-based National Steel Car Ltd. filed a notice of appeal in July after Ontario Superior Court Justice Wendy Matheson ruled in June that an electricity fee known as the global adjustment charge was a regulatory charge, and not an unconstitutional tax used to finance policy goals, as National Steel Car alleges.

The company, the decision noted, began its legal crusade last year after seeing its electricity bills had “increased dramatically” since the Ontario government passed green energy legislation nearly a decade ago, and amid concerns that high electricity rates are hurting Ontario manufacturers.

Under that legislation, the judge wrote, “private suppliers of renewable energy were paid to ’feed in’ energy into Ontario’s electricity grid.” The contracts for these so-called “feed-in tariff” contracts, or FIT contracts, were the “primary focus” of the lawsuit.

“The applicant seeks a declaration that part of the amount it has paid for electricity is an unconstitutional tax rather than a valid regulatory charge,” the judge added. “More specifically, it challenges part of the Global Adjustment, which is a component of electricity pricing and incorporates obligations under FIT contracts.”

Chiefly representing the difference between Ontario’s market price for power and the guaranteed price owed to generators, global adjustment now makes up the bulk of the commodity cost of electricity in the province. The fee has risen over the past decade, amid calls to reject steep Nova Scotia rate hikes as well — costing electricity customers $37 billion in global adjustment from 2006 to 2014, according to the province’s auditor general — because of investments in the electricity grid and green-energy contracts, among other reasons.

National Steel Car argued the global adjustment is a tax, and an unconstitutional one at that because it violated a section of the Constitution Act requiring taxes to be authorized by the legislature. The company also said the imposition of the global adjustment broke an Ontario law requiring a referendum to be held for new taxes.

The province, Justice Matheson wrote, had argued “that it is plain and obvious that these applications will fail.” In a decision released in June, the judge granted motions to strike out National Steel Car’s applications.

“The Global Adjustment,” she added, “is not a tax because its purpose, in pith and substance, is not to tax, and it is a regulatory charge and therefore, again, not a tax.”

Now, National Steel Car is arguing that the judge erred in several ways, including in fact, “by finding that the FIT contracts must be paid, when they can be cancelled.”

There has been a change in government at Queen’s Park since National Steel Car first filed its lawsuit last year, and that change has put green energy contracts under fire. The Progressive Conservative government of new Premier Doug Ford has already made a number of decisions on the electricity file, such as moving to cancel and wind down more than 750 renewable energy contracts, as well as repealing the province’s Green Energy Act.

The Tories also struck a commission of inquiry into the province’s finances that warned the global adjustment “may be struck down as unconstitutional,” a warning delivered amid cases where Nova Scotia's regulator approved a 14% rate hike in a high-profile decision.

“There is a risk that a court may find the global adjustment is not a valid regulatory charge if shifting costs over a longer period of time inadvertently results in future ratepayers cross-subsidizing today’s ratepayers,” the commission’s report said.

A spokesperson for Ontario’s Ministry of Energy, Northern Development and Mines said in an email that it would be “inappropriate to comment about the specifics of any case before the courts or currently under arbitration.”

National Steel Car is also prepared to fight its case all the way up to the Supreme Court of Canada, according to its lawyer.

“What is clear from our proceeding with the appeal is National Steel Car has every intention of seeing that lawsuit through to its conclusion if this government isn’t interested or prepared to reasonably settle it,” Jerome Morse said.

Alberta Electricity Price Surge reflects soaring wholesale rates, natural gas spikes, carbon tax pressures, and grid decarbonization challenges amid cold-weather demand, constrained supply, and Europe-style energy crisis impacts across the province.

Key Points

An exceptional jump in Alberta's power costs driven by gas price spikes, high demand, policy costs, and tight supply.

✅ Wholesale prices averaged $123/MWh in December

✅ Gas costs surged; supply constraints and outages

✅ Carbon tax and decarbonization policies raised costs

Albertans just endured the highest electricity prices in 21 years. Wholesale prices averaged $123 per megawatt-hour in December, more than triple the level from the previous year and highest for December since 2000.

The situation in Alberta mirrors the energy crisis striking Europe where electricity prices are also surging, largely due to a shocking five-fold increase in natural gas prices in 2021 compared to the prior year.

The situation should give pause to Albertans when they consider aggressive plans to “decarbonize” the electric grid, including proposals for a fully renewable grid by 2030 from some policymakers.

The explanation for skyrocketing energy prices is simple: increased demand (because of Calgary's frigid February demand and a slowly-reviving post-pandemic economy) coupled with constrained supply.

In the nitty gritty details, there are always particular transitory causes, such as disputes with Russian gas companies (in the case of Europe) or plant outages (in the case of Alberta).

But beyond these fleeting factors, there are more permanent systemic constraints on natural gas (and even more so, coal-fired) power plants.

I refer of course to the climate change policies of the Trudeau government at the federal level and some of the more aggressive provincial governments, which have notable implications for electricity grids across Canada.

The most obvious example is the carbon tax, the repeal of which Premier Jason Kenney made a staple of his government.

Putting aside the constitutional issues (on which the Supreme Court ruled in March of last year that the federal government could impose a carbon tax on Alberta), the obvious economic impact will be to make carbon-sourced electricity more expensive.

This isn’t a bug or undesired side-effect, it’s the explicit purpose of a carbon tax.

Right now, the federal carbon tax is $40 per tonne, is scheduled to increase to $50 in April, and will ultimately max out at a whopping $170 per tonne in 2030.

Again, the conscious rationale of the tax, aligned with goals for cleaning up Canada's electricity, is to make coal, oil and natural gas more expensive to induce consumers and businesses to use alternative energy sources.

As Albertans experience sticker shock this winter, they should ask themselves — do we want the government intentionally making electricity and heating oil more expensive?

Of course, the proponent of a carbon tax (and other measures designed to shift Canadians away from carbon-based fuels) would respond that it’s a necessary measure in the fight against climate change, and that Canada will need more electricity to hit net-zero according to the IEA.

Yet the reality is that Canada is a bit player on the world stage when it comes to carbon dioxide, responsible for only 1.5% of global emissions (as of 2018).

As reported at this “climate tracker” website, if we look at the actual policies put in place by governments around the world, they’re collectively on track for the Earth to warm 2.7 degrees Celsius by 2100, far above the official target codified in the Paris Agreement.

Canadians can’t do much to alter the global temperature, but federal and provincial governments can make energy more expensive if policymakers so choose, and large-scale electrification could be costly—the Canadian Gas Association warns of $1.4 trillion— if pursued rapidly.

As renewable technologies become more reliable and affordable, business and consumers will naturally adopt them; it didn’t take a “manure tax” to force people to use cars rather than horses.

As official policy continues to make electricity more expensive, Albertans should ask if this approach is really worth it, or whether options like bridging the Alberta-B.C. electricity gap could better balance costs.
