The effort to create a broadband-over-powerline (BPL) standard at the IEEE has passed a significant milestone. The working group for this standard, which contains major companies at all points of the BPL value chain, has developed over 400 requirements for the baseline BPL standard and issued a call for proposals to obtain technical solutions for systems that meet these requirements. Proposals are due by June 4.

The standard, IEEE P1901, “Standard for Broadband over Power Line Networks: Medium Access Control and Physical Layer Specifications”, will be a comprehensive specification needed to send high-speed digital data over the power lines between substations and homes and offices. It also will provide for digital voice, data and video signals to be carried over and accessed from electrical lines within structures.

“Gaining agreement for BPL system requirements is a major achievement and clears the way for the working group to create a solid standard,” says Jean-Philippe Faure, chair of the IEEE P1901 Working Group and vice president-standardization at Ilevo. “The agreement we’ve gotten on this detailed foundation makes me confident that we will create in 2008 a global draft standard that will enable companies worldwide to manufacture the components and systems needed to develop the BPL industry.”

The call for proposal addresses functional and technical requirements in three areas: an access cluster that provides for transmission of broadband content on the medium- and low-voltage power lines that feed homes; an in-home cluster that allows low-voltage wiring in structures to carry digital content; and a coexistence and interoperability cluster that ensures all equipment and devices used on BPL networks are compatible.

The access cluster sets requirements for bringing multimedia services to residences via power lines and for developing electric utility applications. This involves head-end hardware that extracts Internet signals from fiber-optic cables and places them on the current running through power lines, repeaters on distribution lines that keep the signal viable, and customer premise equipment that extracts the signal for use in a structure.

In-home requirements address the use of the power lines in a residence or office as a digital broadcasting medium for the spread of ISP broadband services inside the home, computer applications, whether from one computer to another or to peripherals, as well as for consumer electronics audio, video and other applications.

Coexistence and interoperability considerations are important because of the many devices that may be on a BPL network. This cluster involves protocols that govern how hardware for various applications can share the medium without interfering.

The working group will evaluate and select proposals that best meet the requirements of each cluster. “The goal is to create the best technical standard, whether from one or many sources,” says Faure. “The technologies chosen will form the baseline for the standard, which will allow the full standard to be written and companies to begin creating and testing prototypes of BPL hardware.”

In addition to land-based systems, the working group has begun to extend its efforts to include BPL capabilities for planes, ships, and trains. The goal is to give those who manufacture such transportation platforms an alternative approach to networking digital information.

A new material made from carbon nanotubes can generate electricity by scavenging energy from its environment

Carbon Nanotube Solvent Electricity enables wire-free electrochemistry as organic solvents like acetonitrile pull electrons, powering alcohol oxidation and packed bed reactors, energy harvesting, and micro- and nanoscale robots via redox-driven current.

 

Key Points

Solvent-driven electron extraction from carbon nanotube particles generates current for electrochemistry.

✅ 0.7 V per particle via solvent-induced electron flow

✅ Packed bed reactors drive alcohol oxidation without wires

✅ Scalable for micro- and nanoscale robots; energy harvesting

 

MIT engineers have discovered a new way of generating electricity, alongside advances in renewable power at night that broaden what's possible, using tiny carbon particles that can create a current simply by interacting with liquid surrounding them.

The liquid, an organic solvent, draws electrons out of the particles, generating a current, unlike devices based on a cheap thermoelectric material that rely on heat, that could be used to drive chemical reactions or to power micro- or nanoscale robots, the researchers say.

"This mechanism is new, and this way of generating energy is completely new," says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. "This technology is intriguing because all you have to do is flow a solvent through a bed of these particles. This allows you to do electrochemistry, but with no wires."

In a new study describing this phenomenon, the researchers showed that they could use this electric current to drive a reaction known as alcohol oxidation—an organic chemical reaction that is important in the chemical industry.

Strano is the senior author of the paper, which appears today in Nature Communications. The lead authors of the study are MIT graduate student Albert Tianxiang Liu and former MIT researcher Yuichiro Kunai. Other authors include former graduate student Anton Cottrill, postdocs Amir Kaplan and Hyunah Kim, graduate student Ge Zhang, and recent MIT graduates Rafid Mollah and Yannick Eatmon.

Unique properties
The new discovery grew out of Strano's research on carbon nanotubes—hollow tubes made of a lattice of carbon atoms, which have unique electrical properties. In 2010, Strano demonstrated, for the first time, that carbon nanotubes can generate "thermopower waves." When a carbon nanotube is coated with layer of fuel, moving pulses of heat, or thermopower waves, travel along the tube, creating an electrical current that exemplifies turning thermal energy into electricity in nanoscale systems.

That work led Strano and his students to uncover a related feature of carbon nanotubes. They found that when part of a nanotube is coated with a Teflon-like polymer, it creates an asymmetry, distinct from conventional thermoelectric materials approaches, that makes it possible for electrons to flow from the coated to the uncoated part of the tube, generating an electrical current. Those electrons can be drawn out by submerging the particles in a solvent that is hungry for electrons.

To harness this special capability, the researchers created electricity-generating particles by grinding up carbon nanotubes and forming them into a sheet of paper-like material. One side of each sheet was coated with a Teflon-like polymer, and the researchers then cut out small particles, which can be any shape or size. For this study, they made particles that were 250 microns by 250 microns.

When these particles are submerged in an organic solvent such as acetonitrile, the solvent adheres to the uncoated surface of the particles and begins pulling electrons out of them.

"The solvent takes electrons away, and the system tries to equilibrate by moving electrons," Strano says. "There's no sophisticated battery chemistry inside. It's just a particle and you put it into solvent and it starts generating an electric field."

Particle power
The current version of the particles can generate about 0.7 volts of electricity per particle. In this study, the researchers also showed that they can form arrays of hundreds of particles in a small test tube. This "packed bed" reactor, unlike thin-film waste-heat harvesters for electronics, generates enough energy to power a chemical reaction called an alcohol oxidation, in which an alcohol is converted to an aldehyde or a ketone. Usually, this reaction is not performed using electrochemistry because it would require too much external current.

"Because the packed bed reactor is compact, it has more flexibility in terms of applications than a large electrochemical reactor," Zhang says. "The particles can be made very small, and they don't require any external wires in order to drive the electrochemical reaction."

In future work, Strano hopes to use this kind of energy generation to build polymers using only carbon dioxide as a starting material. In a related project, he has already created polymers that can regenerate themselves using carbon dioxide as a building material, in a process powered by solar energy and informed by devices that generate electricity at night as a complement. This work is inspired by carbon fixation, the set of chemical reactions that plants use to build sugars from carbon dioxide, using energy from the sun.

In the longer term, this approach could also be used to power micro- or nanoscale robots. Strano's lab has already begun building robots at that scale, which could one day be used as diagnostic or environmental sensors. The idea of being able to scavenge energy from the environment, including approaches that produce electricity 'out of thin air' in ambient conditions, to power these kinds of robots is appealing, he says.

"It means you don't have to put the energy storage on board," he says. "What we like about this mechanism is that you can take the energy, at least in part, from the environment."

Aging U.S. power grid threatens progress on renewables, EVs

U.S. Grid Modernization is critical for renewable energy integration, EV adoption, climate resilience, and reliability, requiring transmission upgrades, inter-regional links, hardened substations, and smart grid investments to handle extreme weather and decarbonization targets.

 

Key Points

U.S. Grid Modernization upgrades power networks to improve reliability, integrate renewables, and support EV demand.

✅ $2T+ investment needed for transmission upgrades

✅ Extreme weather doubling outages since 2017

✅ Regulatory fragmentation slows inter-regional lines

 

After decades of struggle, the U.S. clean-energy business is booming, with soaring electric-car sales and fast growth in wind and solar power. That’s raising hopes for the fight against climate change.

All this progress, however, could be derailed, as the green revolution stalls without a massive overhaul of America’s antiquated electric infrastructure – a task some industry experts say requires more than $2 trillion. The current network of transmission wires, substations and transformers is decaying with age and underinvestment, a condition highlighted by catastrophic failures during increasingly frequent and severe weather events.

Power outages over the last six years have more than doubled in number compared to the previous six years, according to a Reuters examination of federal data. In the past two years, power systems have collapsed in Gulf Coast hurricanes, West Coast wildfires, Midwest heat waves and a Texas deep freeze and recurring Texas grid crisis risks, causing long and sometimes deadly outages.

Compounding the problem, the seven regional grid operators in the United States are underestimating the growing threat of severe weather caused by climate change, Reuters found in a review of more than 10,000 pages of regulatory documents and operators’ public disclosures. Their risk models, used to guide transmission-network investments, consider historical weather patterns extending as far back as the 1970s. None account for scientific research documenting today’s more extreme weather and how it can disrupt grid generation, transmission and fuel supplies simultaneously.

The decrepit power infrastructure of the world’s largest economy is among the biggest obstacles to expanding clean energy and combating climate change on the ambitious schedule laid out by U.S. President Joe Biden. His administration promises to eliminate or offset carbon emissions from the power sector by 2035 and from the entire U.S. economy by 2050. Such rapid clean-energy growth would pressure the nation’s grid in two ways: Widespread EV adoption will spark a huge surge in power demand; and increasing dependence on renewable power creates reliability problems on days with less sun or wind, as seen in Texas, where experts have outlined reliability improvements that address these challenges.

The U.S. transmission network has seen outages double in recent years amid more frequent and severe weather events, driven by climate change and a utility supply-chain crunch that slows critical repairs. The system needs a massive upgrade to handle expected growth in clean energy and electric cars. 

“Competition from renewables is being strangled without adequate and necessary upgrades to the transmission network,” said Simon Mahan, executive director of the Southern Renewable Energy Association, which represents solar and wind companies.

The federal government, however, lacks the authority to push through the massive grid expansion and modernization needed to withstand wilder weather and accommodate EVs and renewable power. Under the current regulatory regime, and amid contentious electricity pricing proposals in recent years, the needed infrastructure investments are instead controlled by a Byzantine web of local, state and regional regulators who have strong political incentives to hold down spending, according to Reuters interviews with grid operators, federal and state regulators, and executives from utilities and construction firms.

“Competition from renewables is being strangled without adequate and necessary upgrades to the transmission network.”

Paying for major grid upgrades would require these regulators to sign off on rate increases likely to spark strong opposition from consumers and local and state politicians, who are keen to keep utility bills low. In addition, utility companies often fight investments in transmission-network improvements because they can result in new connections to other regional grids that could allow rival companies to compete on their turf, even as coal and nuclear disruptions raise brownout risks in some regions. With the advance of green energy, those inter-regional connections will become ever more essential to move power from far-flung solar and wind installations to population centers.

The power-sharing among states and regions with often conflicting interests makes it extremely challenging to coordinate any national strategy to modernize the grid, said Alison Silverstein, an independent industry consultant and former senior adviser to the U.S. Federal Energy Regulatory Commission (FERC).

“The politics are a freakin’ nightmare,” she said.

The FERC declined to comment for this story. FERC Commissioner Mark Christie, a Republican, acknowledged the limitations of the agency’s power over the U.S. grid in an April 21 agency meeting involving transmission planning and costs.

“We can’t force states to do anything,” Christie said.

The White House and Energy Department did not comment in response to detailed questions from Reuters on the Biden administration’s plans to tackle U.S. grid problems and their impact on green-energy expansion.

The administration said in an April news release that it plans to offer $2.5 billion in grants for grid-modernization projects as part of Biden’s $1 trillion infrastructure package, complementing a proposed clean electricity standard to accelerate decarbonization over the next decade. A modernized grid, the release said, is the “linchpin” of Biden’s clean-energy agenda.

Idaho Power Settlement Could Close Coal Plant, Raise Rates

Idaho Power Valmy Settlement outlines early closure of the North Valmy coal-fired plant in Nevada, accelerated depreciation recovery, a 1.17% base-rate increase, and impacts for customers, NV Energy co-ownership, and Idaho Public Utilities Commission review.

 

Key Points

A proposed agreement to close North Valmy early, recover costs via a 1.17% rate hike, and seek PUC approval.

✅ Unit 1 closes 2019; Unit 2 closes 2025 in Nevada.

✅ 1.17% base-rate hike; about $1.20 per 1,000 kWh monthly bill.

✅ Idaho PUC comment deadline May 25; NV Energy co-owner.

 

State regulators have set a May 25 deadline for public comment on a proposed settlement related to the early closure of a coal-fired plant co-owned by Idaho Power, even as some utilities plan to keep a U.S. coal plant running indefinitely in other jurisdictions.

The settlement calls for shuttering Unit 1 of the North Valmy Power Plant in Nevada in 2019, with Unit 2 closing in 2025, amid regional coal unit retirements debates. The units had been slated for closure in 2031 and 2035, respectively.

If approved by the Idaho Public Utilities Commission, the settlement would increase base rates by approximately $13.3 million, or 1.17 percent, in order to allow the company to recover its investment in the plant on an accelerated basis.

That equates to an additional $1.20 on the monthly bill of the typical residential customer using 1,000 kilowatt-hours of energy per month.

Idaho Power, which co-owns the plant with NV Energy, maintains that closing Valmy early rather than continuing to operate it until it is fully depreciated in 2035, will ultimately save customers $103 million in today's dollars.

The company said a significant decrease in market prices for electricity has made it uneconomic to operate the plant except during extremely cold or hot weather, when the demand for energy peaks, a trend underscored by transactions involving the San Juan Generating Station deal elsewhere. The company also said plant balances have increased by approximately $70 million since its last general rate case in 2011, due to routine maintenance and repairs, as well as investments required to meet environmental regulations.

The proposed settlement reflects a number of changes to Idaho Power's original proposal regarding Valmy, and comes in the wake of discussions with interested parties in February and April, against the backdrop of a broader energy debate over plant closures and reliability.

In its initial application, filed in October, Idaho Power proposed closing both units in 2025. The original proposal would have increased base rates by $28.5 million, or about 2.5 percent, in order to allow the company to recover its costs associated with the plant's accelerated depreciation, decommissioning and anticipated investments, with cautionary examples such as the Kemper power plant costs illustrating potential risks.

Concurrently, Idaho Power asked for commission approval to adjust depreciation rates for its other plants and equipment based on the result of a study it conducts every five years, as outlined in Case IPC-E-16-23. The adjustment would have led to a $6.7 million increase to base rates.

The two requests filed in October would have increased customer costs by a total of $35.2 million or 3.1 percent, leading to a $3.08 increase on the bills of the typical residential customer who uses 1,000 kilowatt-hours per month.

The proposed settlement submitted to the Commission on May 4 calls for $13,285,285 to be recovered from all customer classes through base rates until 2028, all related to the Valmy shutdown. That is an increase of 1.17 percent and would result in a $1.20 increase on the bills of the typical residential customer who uses 1,000 kilowatt-hours per month.

Solar PV and wind power in the US continue to grow amid favourable government plans

US Renewable Power Outlook 2030 projects surging capacity, solar PV and wind growth, grid modernization, and favorable tax credits, detailing market trends, CAGR, transmission expansion, and policy drivers shaping clean energy generation and consumption.

 

Key Points

A forecast of US power capacity, generation, and consumption, highlighting solar, wind, tax credits, and grid modernization.

✅ Targets 48.4% renewable capacity share by 2030

✅ Strong growth in solar PV and onshore wind installations

✅ Investment and tax credits drive grid and transmission upgrades

 

GlobalData’s latest report, ‘United States Power Market Outlook to 2030, Update 2021 – Market Trends, Regulations, and Competitive Landscape’ discusses the power market structure of the United States and provides historical and forecast numbers for capacity, generation and consumption up to 2030. Detailed analysis of the country’s power market regulatory structure, competitive landscape and a list of major power plants are provided. The report also gives a snapshot of the power sector in the country on broad parameters of macroeconomics, supply security, generation infrastructure, transmission and distribution infrastructure, about a quarter of U.S. electricity from renewables in recent years, electricity import and export scenario, degree of competition, regulatory scenario, and future potential. An analysis of the deals in the country’s power sector is also included in the report.

Renewable power held a 19% share of the US’s total power capacity in 2020, and in that year renewables became the second-most prevalent source in the U.S. electricity mix by generation; this share is expected to increase significantly to 48.4% by 2030. Favourable policies introduced by the US Government will continue to drive the country’s renewable sector, particularly solar photovoltaics (PV) and wind power, with wind now the most-used renewable source in the U.S. generation mix. Installed renewable capacity* increased from 16.5GW in 2000 to 239.2GW in 2020, growing at a compound annual growth rate (CAGR) of 14.3%. By 2030, the cumulative renewable capacity is expected to rise to 884.6GW, growing at a CAGR of 14% from 2020 to 2030. Despite increase in prices of renewable equipment, such as solar modules, in 2021, the US renewable sector will show strong growth during the 2021 to 2030 period as this increase in equipment prices are short term due to supply chain disruptions caused by the Covid-19 pandemic.

The expansion of renewable power capacity during the 2000 to 2020 period has been possible due to the introduction of federal schemes, such as Production Tax Credits, Investment Tax Credits and Manufacturing Tax Credits. These have massively aided renewable installations by bringing down the cost of renewable power generation and making it at par with power generated from conventional sources. Over the last few years, the cost of solar PV and wind power installations has declined sharply, and by 2023 wind, solar, and batteries made up most of the utility-scale pipeline across the US, highlighting investor confidence. Since 2010, the cost of utility-scale solar PV projects decreased by around 82% while onshore wind installations decreased by around 39%. This has supported the rapid expansion of the renewable market. However, the price of solar equipment has risen due to an increase in raw material prices and supply shortages. This may slightly delay the financing of some solar projects that are already in the pipeline.

The US will continue to add significant renewable capacity additions during the forecast period as industry outlooks point to record solar and storage installations over the coming years, to meet its target of reaching 80% clean energy by 2030. In November 2021, President Biden signed a $1tr Infrastructure Bill, within which $73bn is designated to renewables. This includes not just renewable capacity building, but also strengthening the country’s power grid and laying new high voltage transmission lines, both of which will be key to driving solar and wind power capacity additions as wind power surges in the U.S. electricity mix nationwide.

The US was one of the worst hit countries in the world due to the Covid-19 pandemic in 2020. With respect to the power sector, the electricity consumption in the country declined by 2.5% in 2020 as compared to 2019, even as renewable electricity surpassed coal in 2022 in the generation mix, highlighting continued structural change. Power plants that were under construction faced delays due to unavailability of components due to supply chain disruptions and unavailability of labour due to travel restrictions.

According to the US Energy Information Administration, 61 power projects, having a total capacity of 2.4GWm which were under construction during March and April 2020 were delayed because of the Covid-19 pandemic. Among renewable power technologies, solar PV and wind power projects were the most badly affected due to the pandemic.

In March and April 2020, 53 solar PV projects, having a total capacity of 1.3GW, and wind power projects, having a total capacity of 1.2GW, were delayed due to the Covid-19 pandemic. Moreover, several states suspended renewable energy auctions due to the pandemic.

For instance, New York State Energy Research and Development Authority (NYSERDA) had issued a new offshore wind solicitation for 1GW and up to 2.5GW in April 2020, but this was suspended due to the Covid-19 pandemic. In July 2020, the authority relaunched the tender for 2.5GW of offshore wind capacity, with a submission deadline in October 2020.

To ease the financial burden on consumers during the pandemic, more than 1,000 utilities in the country announced disconnection moratoria and implemented flexible payment plans. Duke Energy, American Electric Power, Dominion Power and Southern California Edison were among the major utilities that voluntarily suspended disconnections.

Opinion: Germany's drive for renewable energy is a cautionary tale

Germany Energiewende Lessons highlight climate policy tradeoffs, as renewables, wind and solar face grid constraints, coal phase-out delays, rising electricity prices, and public opposition, informing Canada on diversification, hydro, oil and gas, and balanced transition.

 

Key Points

Insights from Germany's renewable shift on costs, grid limits, and emissions to guide Canada's balanced energy policy.

✅ Evidence: high power prices, delayed coal exit, limited grid buildout

✅ Land, materials, and wildlife impacts challenge wind and solar scale-up

✅ Diversification: hydro, nuclear, gas, and storage balance reliability

 

News that Greta Thunberg is visiting Alberta should be welcomed by all Canadians.

The teenaged Swedish environmentalist has focused global attention on the climate change debate like never before. So as she tours our province, where selling renewable energy could be Alberta's next big thing, what better time for a reality check than to look at a country that is furthest ahead in already adapting steps that Greta is advocating.

That country is Germany. And it’s not a pretty sight.

Germany embraced the shift toward renewable energy before anyone else, and did so with gusto. The result?

Germany’s largest newsmagazine Der Spiegel published an article on May 3 of this year entitled “A Botched Job in Germany.” The cover showed broken wind turbines and half-finished transition towers against a dark silhouette of Berlin.

Germany’s renewable energy transition, Energiewende, is a bust. After spending and committing a total of US$580 billion to it from 2000 to 2025.

Why is that? Because it’s been a nightmare of foolish dreams based on hope rather than fact, resulting in stalled projects and dreadfully poor returns.

Last year Germany admitted it had to delay its phase-out of coal and would not meet its 2020 greenhouse gas emissions reduction commitment. Only eight per cent of the transmission lines needed to support this new approach to powering Germany have been built.

Opposition to renewables is growing due to electricity prices rising to the point they are now among the highest in the world. Wind energy projects in Germany are now facing the same opposition that pipelines are here in Canada. 

Opposition to renewables in Germany, reports Forbes, is coming from people who live in rural or suburban areas, in opposition to the “urbane, cosmopolitan elites who fetishize their solar roofs and Teslas as a sign of virtue.” Sound familiar?

So, if renewables cannot successfully power Germany, one of the richest and most technologically advanced countries in the world, who can do it better?

The biggest problem with using wind and solar power on a large scale is that the physics just don’t work. They need too much land and equipment to produce sufficient amounts of electricity.

Solar farms take 450 times more land than nuclear power plants to produce the same amount of electricity. Wind farms take 700 times more land than natural gas wells.

The amount of metal required to build these sites is enormous, requiring new mines. Wind farms are killing hundreds of endangered birds.

No amount of marketing or spin can change the poor physics of resource-intensive and land-intensive renewables.

But, wait. Isn’t Norway, Greta’s neighbour, dumping its energy investments and moving into alternative energy like wind farms in a big way?

No, not really. Fact is only 0.8 per cent of Norway’s power comes from wind turbines. The country is blessed with a lot of hydroelectric power, but that’s a historical strength owing to the country’s geography, nothing new.

And yet we’re being told the US$1-trillion Oslo-based Government Pension Fund Global is moving out of the energy sector to instead invest in wind, solar and other alternative energy technologies. According to 350.org activist Nicolo Wojewoda this is “yet another nail in the coffin of the coal, oil, and gas industry.”

Well, no.

Norway’s pension fund is indeed investing in new energy forms, but not while pulling out of traditional investments in oil and gas. Rather, as any prudent fund manager will, they are diversifying by making modest investments in emerging industries such as Alberta's renewable energy surge that will likely pay off down the road while maintaining existing investments, spreading their investments around to reduce risk. Unfortunately for climate alarmists, the reality is far more nuanced and not nearly as explosive as they’d like us to think.

Yet, that’s enough for them to spin this tale to argue Canada should exit oil and gas investment and put all of our money into wind and solar, even as Canada remains a solar power laggard according to experts.

That is not to say renewable energy projects like wind and solar don’t have a place. They do, and we must continue to innovate and research lower-polluting ways to power our societies on the path to zero-emissions electricity by 2035 in Canada.

But like it actually is in Norway, investment in renewables should supplement — not replace — fossil fuel energy systems if we aim for zero-emission electricity in Canada by 2035 without undermining reliability. We need both.

And that’s the message that Greta should hear when she arrives in Canada.

Rick Peterson is the Edmonton-based founder and Beth Bailey is a Calgary-based supporter of Suits and Boots, a national not-for-profit group of investment industry professionals that supports resource sector workers and their families.

UK electricity and gas networks making ‘unjustified’ profits

UK Energy Network Profits are under scrutiny as Ofgem price controls, Citizens Advice claims, and National Grid margins spark debate over monopolies, allowed returns, consumer bills, rebates, and future investment under tougher regulation.

 

Key Points

UK Energy Network Profits are returns set by Ofgem for regulated grid operators, shaping consumer bills and investment

✅ Ofgem sets allowed returns for monopoly networks via price controls

✅ Dispute over interest rates, bond yields, and risk premiums

✅ Reforms proposed: shorter controls, tougher investor incentives

 

Companies that run Britain’s electricity and gas networks, including National Grid, are making “eye-watering” profits at the expense of households, according to a well-known consumer group.

Citizens Advice believes £7.5bn in “unjustified” profits should be returned to consumers who pay for network costs via their electricity and gas bills, with parallels seen in a deferred BC Hydro costs report abroad, although its figures have been contested by the energy industry and regulator.

Ownership of electricity and gas networks came under the spotlight in the run-up to June’s general election, after the Labour party said in its manifesto it would bring both national and regional grid infrastructure to back into public ownership, amid wider debates about grid privatization concerns elsewhere, over time.

Electricity sector privatisation began in 1990 and the gas industry was privatised in 1986. Energy network companies — which own and operate the cables and wires that help deliver electricity and gas to homes and businesses — are in effect monopolies that are regulated by Ofgem. Ofgem evaluates what their costs, including the cost of capital to finance investments, might be over an eight-year “price control” period, similar to determinations like the OEB decision on Hydro One rates in Ontario, Canada. Citizens Advice claims many of the regulator’s calculations for the most recent price control went “considerably in networks’ financial favour”.

It believes assumptions Ofgem made about factors such as the future path of interest rates and returns on government bonds were too generous, with international contrasts like power theft challenges in India illustrating different risk contexts, as was the regulator’s assessment of the risk associated with operating a network company. 

These “generous” assumptions will lead to network companies making average profit margins of 19 per cent and an average return of 10 per cent for their investors at the expense of consumers, Citizens Advice claims in a report published on Wednesday, which recommends a shorter price control period to allow for more accurate forecasting.

“Decisions made by Ofgem have allowed gas and electricity network companies to make sky-high profits that we’ve found are not justified by their performance,” said Gillian Guy, chief executive of Citizens Advice. Ofgem defended its regulatory regime, saying it helped to cut costs, improve reliability and customer satisfaction. 

“Ofgem has already cut costs to consumers by 6 per cent in the current price control and secured a rebate of over £4.5bn from network companies and is engaging with the industry to deliver further savings, with some regions seeing Ontario electricity rate reductions for businesses as well,” said Dermot Nolan, chief executive of the energy regulator.

Mr Nolan insisted the next price controls would be “tougher for investors”. The current price controls for the gas and electricity transmission networks, plus gas distribution, run until 2021 and until 2023 for local electricity distribution networks.

“While we don’t agree with its modelling and the figures it has produced, the Citizens Advice report raises some important issues about network regulation which will be addressed in the next control,” Mr Nolan said.

The Energy Networks Association, a trade body, refuted the claims of Citizens Advice, insisting that costs had fallen by 17 per cent in real terms since privatisation. The current regulatory framework was established after a public consultation, it said, adding that today’s report repeated several old claims that had previously been rejected by the Competition and Markets Authority.

“Our energy networks are among the most reliable and lowest cost in the world and their performance has never been better. In the next six years energy network companies are forecasted to deliver £45bn of investment in the UK economy,” a spokesman for the networks association added. National Grid said that since 2013 it had generated savings of £460m for bill payers.
