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.

Manitoba Government Extends Pause on New Cryptocurrency Connections

Manitoba Crypto Mining Electricity Pause signals a moratorium to manage grid strain, Manitoba Hydro capacity, infrastructure costs, and electricity rates, while policymakers evaluate sustainable energy demand, and planning for data centers and blockchain operations.

 

Key Points

A temporary halt on mining power hookups in Manitoba to assess grid impacts, protect rates, and plan sustainable use.

✅ Applies only to new service requests; existing sites unaffected

✅ Addresses grid strain, infrastructure costs, electricity rates

✅ Enables review with Manitoba Hydro for sustainable policy

 

The Manitoba government has temporarily suspended approving new electricity service connections for cryptocurrency mining operations, a step similar to BC Hydro's suspension seen in a neighboring province.


The Original Pause

The pause was initially imposed in November 2022 due to concerns that the rapid influx of cryptocurrency mining operations could place significant strain on the province's electrical grid. Manitoba Hydro, the province's primary electric utility, which has also faced legal scrutiny in the Sycamore Energy lawsuit, warned that unregulated expansion of the industry could necessitate billions of dollars in infrastructure investments, potentially driving up electricity rates for Manitobans.


The Extended Pause Offers Time for Review

The extension of the pause is meant to provide the government and Manitoba Hydro with more time to assess the situation thoroughly and develop a long-term solution addressing the challenges and opportunities presented by cryptocurrency mining, including evaluating emerging options such as modular nuclear reactors that other jurisdictions are studying. The government has stated its commitment to ensuring that the long-term impacts of the industry are understood and don't unintentionally harm other electricity customers.


What Does the Pause Mean?

The pause does not affect existing cryptocurrency operations but prevents the establishment of new ones.  It applies specifically to requests for electricity service that haven't yet resulted in agreements to construct infrastructure or supply electricity, and it comes amid regional policy shifts like Alberta ending its renewable moratorium that also affect grid planning.


Concerns About Energy Demands

Cryptocurrency mining involves running high-powered computers around the clock to solve complex mathematical problems. This process is incredibly energy-intensive. Globally, the energy consumption of cryptocurrency networks has drawn scrutiny for its environmental impact, with examples such as Iceland's mining power use illustrating the scale. In Manitoba, concern focuses on potentially straining the electrical grid and making it difficult for Manitoba Hydro to plan for future growth.


Other Jurisdictions Taking Similar Steps

Manitoba is not alone in its cautionary approach to cryptocurrency mining. Several other regions and utilities have implemented restrictions or are exploring limitations on how cryptocurrency miners can access electricity, including moves by Russia to ban mining amid power deficits. This reflects a growing awareness among policymakers about the potentially destabilizing impact this industry could have on power grids and electricity markets.


Finding a Sustainable Path Forward

Manitoba Hydro has stated that it is open to working with cryptocurrency operations but emphasizes the need to do so in a way that protects existing ratepayers and ensures a stable and reliable electricity system for all Manitobans, while recognizing market uncertainties highlighted by Alberta wind project challenges in a neighboring province. The government's extension of the pause signifies its intention to find a responsible path forward, balancing the potential for economic development with the necessity of safeguarding the province's power supply.

Plan to End E-Vehicle Subsidies Sparks Anger in Germany

Germany EV Subsidy Cut triggers budget-crisis fallout in the automotive industry, after a constitutional court ruling; EV incentives end, threatening electromobility adoption, manufacturer competitiveness, 2030 targets, and demand amid Chinese competition and weak global growth.

 

Key Points

A sudden end to Germany's EV incentives due to a budget shortfall after a court ruling, hurting automakers and adoption.

✅ Ends buyer rebates amid budget crisis ruling

✅ Risks 2030 EV targets and industry competitiveness

✅ Weak demand and China competition intensify

 

The German government has faced a backlash after abruptly ending an electric car subsidy scheme in a blow to the already struggling automotive industry.

The scheme is one of the casualties of a budget crisis caused by a shock constitutional court ruling in November that upended the government's spending plans.

The economy ministry said Saturday that Sunday would be the last day prospective buyers could apply for the scheme, which paid out thousands of euros per customer to partially cover the cost of buying an electric car today.

A spokesman for the ministry admitted it was an "unfortunate situation" for consumers who had been hoping to take advantage of the subsidy, but it had no choice "because there is no longer enough money available."

Analyst Ferdinand Dudenhoeffer from the Center for Automotive Research warned the decision could have dramatic consequences amid a Europe EV slump already pressuring demand.

"The competitiveness of [auto] manufacturers will now be severely damaged," Dudenhoeffer told the Rheinische Post newspaper.

The Handelsblatt business daily had already warned that scrapping the scheme risked jeopardizing Germany's plans to get 15 million electric cars on the road by 2030, even though the EU EV share grew during lockdowns earlier in the pandemic.

"This goal was already considered extremely unrealistic. Now it seems completely illusory," it wrote.

In the UK, analysts warn that electric cars could cost more if a post-Brexit deal is not reached, underscoring wider market uncertainties.

A total of around 10 billion euros ($1.1 billion) has been paid out since 2016 under the scheme for around 2.1 million electric vehicles, according to the economy ministry.

Germany's flagship automotive industry, including Volkswagen, has been struggling with the transition to electromobility due to a weak global economy and low levels of demand.

In addition, it is facing a serious challenge from homegrown rivals in China, one of its most important markets, as France moves to discourage Chinese EVs with new rules.

"The Chinese are massively expanding their car industry because they have customers. Our manufacturers no longer have any," Dudenhoeffer said, as France's incentive rules make the market tougher for Chinese brands.

Germany's highest court decided last month that the government had broken a constitutional debt rule when it transferred 60 billion euros earmarked for pandemic support to a climate fund.

The bombshell ruling blew a huge hole in spending plans and plunged Chancellor Olaf Scholz's three-way coalition into turmoil.

After adopting an emergency budget for 2023, Scholz and his junior coalition partners battled for weeks before finally finding an agreement for 2024.

U.S. Residents Averaged Fewer Power Outages in 2022

2022 U.S. Power Outage Statistics show lower SAIDI as fewer major events hit, with SAIFI trends, electric reliability, outage duration and frequency shaped by hurricanes, winter storms, vegetation, and utility practices across states.

 

Key Points

They report SAIDI and SAIFI for 2022, showing outage duration, frequency, and impacts of major weather events.

✅ 2022 SAIDI averaged 5.6 hours; SAIFI averaged 1.4 interruptions.

✅ Fewer major events lowered outage duration versus 2021.

✅ Hurricanes and winter storms drove long outages in several states.

 

In 2022, U.S. electricity consumers on average experienced about 5.5 hours of power disruptions, a decrease from nearly two hours compared to 2021. This information comes from the latest Annual Electric Power Industry Report. The reduction in yearly power interruptions primarily resulted from fewer significant events in 2022 compared to the previous year, and utility disaster planning continues to support grid resilience as severe weather persists.

Since 2013, excluding major events, the annual average duration of power interruptions has consistently hovered around two hours. Factors contributing to major power disruptions include weather-related incidents, vegetation interference near power lines, and specific utility practices, while pandemic-related grid operations influenced workforce planning more than outage frequency. To assess the reliability of U.S. electric utilities, two key indexes are utilized:

  • The System Average Interruption Duration Index (SAIDI) calculates the total length (in hours) an average customer endures non-brief power interruptions over a year.
  • The System Average Interruption Frequency Index (SAIFI) tracks the number of times interruptions occur.

The influence of major events on electrical reliability is gauged by comparing affected states' SAIDI and SAIFI values against the U.S. average, which was 5.6 hours of outages and 1.4 outages per customer in 2022. The year witnessed 18 weather-related disasters in the U.S., each resulting in over $1 billion in damages, and COVID-19 grid assessments indicated the electricity system was largely safe from pandemic impacts. Noteworthy major events include:

  • Hurricane Ian in September 2022, leaving over 2.6 million Floridian customers without electricity, with restoration in some areas taking weeks rather than days.
  • Hurricane Nicole in November 2022, causing over 300,000 Florida customers to lose power.
  • Winter Storm Elliott in December 2022, affecting over 1.5 million customers in multiple states including Texas where utilities struggled after Hurricane Harvey to restore service, and Florida, and bringing up to four feet of snow in parts of New York.

In 2022, states like Florida, West Virginia, Maine, Vermont, and New Hampshire experienced the most prolonged power interruptions, with New Hampshire averaging 10.3 hours and Florida 19.1 hours, and FPL's Irma storm response illustrates how restoration can take days or weeks in severe cases. Conversely, the District of Columbia, Delaware, Rhode Island, Nebraska, and Iowa had the shortest total interruptions, with the District of Columbia averaging just 34 minutes and Iowa 85 minutes.

The frequency of outages, unlike their duration, is more often linked to non-major events. Across the nation, Alaska recorded the highest number of power disruptions per customer (averaging 3.5), followed by several heavily forested states like Tennessee and Maine. Power outages due to falling tree branches are common, particularly during winter storms that burden tree limbs and power lines, as seen in a North Seattle outage affecting 13,000 customers. The District of Columbia stood out with the shortest and fewest outages per customer.

Biden administration pushes to revitalize coal communities with clean energy projects

Coal-to-Clean Energy Hubs leverage Bipartisan Infrastructure Law and Inflation Reduction Act funding to repurpose mine lands with microgrids, advanced nuclear, carbon capture, and rare earth processing, boosting energy security, jobs, and grid modernization.

 

Key Points

They are federal projects converting coal communities and mine lands into clean energy hubs, repurposing infrastructure.

✅ DOE demos on mine lands: microgrids, nuclear, carbon capture.

✅ Funding from BIL, CHIPS and IRA targets energy communities.

✅ Rare earths from coal waste bolster EV supply chains.

 

The Biden administration is channeling hundreds of millions of dollars in clean energy funding from recent legislation into its efforts to turn coal communities into clean energy hubs, the White House said.

The administration gave an update on its push across agencies to kick-start projects nationwide with funding Congress approved during Biden’s first two years in office. The effort includes $450 million from the Bipartisan Infrastructure Law that the Department of Energy will allocate to an array of new clean energy demonstration projects on former mine lands.

“These projects could focus on a range of technologies from microgrids to advanced nuclear to power plans with carbon capture,” Energy Secretary Jennifer Granholm said on a call with reporters Monday. “They’ll prove out the potential to reactivate or repurpose existing infrastructure like transmission lines and substations across an aging U.S. power grid, and these projects could spur new economic development in these communities.”

Among the projects the White House highlighted, it said $16 million from the infrastructure law will go to the University of North Dakota and West Virginia University to create design studies for the first-ever full-scale refinery facility in the U.S. that could extract and separate rare earth elements and minerals from coal mine waste streams. The materials are critical for electric vehicle-battery components that are currently heavily sourced from outside the U.S.

“Those efforts will pave the way toward building a first of its kind facility that produces essential materials for solar panels, wind turbines, EVs and more while cleaning up polluted land and water and creating good-paying jobs for local workers,” Granholm said.

Biden created an interagency working group focused on revitalizing coal-power communities through federal investments when he took office. In 2021, the group selected 25 priority areas ranging from West Virginia to Wyoming to focus on development, as high natural gas prices strengthened the case for clean electricity. There are nearly 18,000 identified mine sites across 1.5 million acres in the United States, according to the White House.

The massive effort fits into a broader Biden administration push to both fight climate change and support communities that have lost economic activity during a transition away from fossil fuel sources such as coal. While Biden’s most ambitious clean energy plans fell flat in Congress in the face of opposition from Republicans and some Democrats after the previous administration’s power plant overhaul, three major laws still unlocked funding for his administration to deploy.

Many of the initiatives are made possible through the Bipartisan Infrastructure Law, Chips and Science Act and the Inflation Reduction Act, even without a clean electricity standard on the books. The task force aims to make sure communities most affected by the changing energy landscape are taking maximum advantage of the federal benefits.

“Those new and expanded operations are coming to energy communities and creating good paying jobs,” Biden’s senior advisor for clean energy innovation and implementation John Podesta said on the call. “These laws can provide substantial federal support to energy communities like capping abandoned oil and gas wells, extracting critical minerals, building battery factories and launching demonstration projects in carbon capture or green hydrogen.”

The administration touted the potential benefits of the Inflation Reduction Act, a bill passed by Democrats to spur clean energy investments last year, even as early assessments show mixed results to date. At the time, U.S. consumers were dealing with decades-high inflation fueled in part by an energy crisis and high gas prices that drove debate — a point Republicans emphasized as the plan moved through Congress.

Deputy Treasury Secretary Wally Adeyemo said the Inflation Reduction Act aims to both “lower the deficit, as well as promote our energy security, lowering energy costs for consumers and combatting climate change.”

“As the Treasury works to implement the law, we’re focused on ensuring that all Americans benefit from the growth of the clean energy economy, particularly those who live in communities that have been dependent on the energy sector for job for a long time,” Adeyemo told reporters. “Economic growth and productivity are higher when all communities are able to reach their full potential.”

Germany's Energy Crisis Deepens as Local Utilities Cry for Help

Germany energy liquidity crisis is straining municipal utilities as gas and power prices surge, margin calls rise, and Russian supply cuts bite, forcing state support, interventions, and emergency financing to stabilize households and businesses.

 

Key Points

A cash squeeze on German municipal utilities as soaring gas and power prices trigger margin calls and funding gaps.

✅ Margin calls and spot-market purchases strain cash flow

✅ State liquidity lines and EU collateral support proposed

✅ Gazprom cuts, Uniper distress heighten default risks

 

Germany’s fears that soaring power prices and gas prices could trigger a deeper crisis is starting to get real. 

Several hundred local utilities are coming under strain and need support, according to the head of Germany’s largest energy lobby group. The companies, generally owned by municipalities, supply households and small businesses directly and are a key part of the country’s power and gas network.

“The next step from the government and federal states must be to secure liquidity for these municipal companies,” Kerstin Andreae, chairwoman of the German Association of Energy and Water Industries, told Bloomberg in Berlin. “Prices are rising, and they have no more money to pay the suppliers. This is a big problem.”

Germany’s energy crunch intensified over the weekend after Russia’s Gazprom PJSC halted its key gas pipeline indefinitely, a stark wake-up call for policymakers to reduce fossil fuel dependence. European energy prices have surged again amid concerns over shortages this winter and fears of a worst-case energy scenario across the bloc. 

Many utilities are running into financial issues as they’re forced to cover missing Russian deliveries with expensive supplies on the spot market. German energy giant Uniper SE, which supplies local utilities, warned it will likely burn through a 7 billion-euro ($7 billion) government safety net and will need more help already this month.

Some German local utilities have already sought help, according to a government official, who asked not to be identified in line with briefing rules.  

With Europe’s largest economy already bracing for recession, Chancellor Olaf Scholz’s administration is battling on several fronts, testing the government’s financial capacity. The ruling coalition agreed Sunday on a relief plan worth about 65 billion euros -- part of an emerging energy shield package to contain the fallout of surging costs for households and businesses. 

Starting in October, local utilities will have to pay a levy for the gas acquired, which will further increase their financial burden, Andreae said.

Margin Calls
European gas prices are more than four times higher than usual for this time of year, underscoring why rolling back electricity prices is tougher than it appears for policymakers, as Russia cuts supplies in retaliation for sanctions related to its invasion of Ukraine. When prices peak, energy companies have to pay margin calls, extra collateral required to back their trades.

The problem has hit local utilities in other countries as well. In Austria, the government approved a 2 billion-euro loan for Vienna’s municipal utility last month. 

The European Union is also planning help, floating gas price cap strategies among other tools. The bloc’s emergency measures will include support for electricity producers struggling to find enough cash to guarantee trades, according to European Commission President Ursula von der Leyen.

The situation has worsened in Germany as some of the country’s big gas importers are reluctant to sell more supplies to some of municipal companies amid fears they could default on payments, Andreae said.

New EPA power plant rules will put carbon capture to the test

CCUS in the U.S. Power Sector drives investments as DOE grants, 45Q tax credits, and EPA carbon rules spur carbon capture, geologic storage, and utilization, while debates persist over costs, transparency, reliability, and emissions safeguards.

 

Key Points

CCUS captures CO2 from power plants for storage or use, backed by 45Q tax credits, DOE funding, and EPA carbon rules.

✅ DOE grants and 45Q credits aim to de-risk project economics.

✅ EPA rules may require capture rates to meet emissions limits.

✅ Transparency and MRV guard against tax credit abuse.

 

New public and private funding, including DOE $110M for CCUS announced recently, and expected strong federal power plant emissions reduction standards have accelerated electricity sector investments in carbon capture, utilization and storage,’ or CCUS, projects but some worry it is good money thrown after bad.

CCUS separates carbon from a fossil fuel-burning power plant’s exhaust through carbon capture methods for geologic storage or use in industrial and other applications, according to the Department of Energy. Fossil fuel industry giants like Calpine and Chevron are looking to take advantage of new federal tax credits and grant funding for CCUS to manage potentially high costs in meeting power plant performance requirements, amid growing investor pressure for climate reporting, including new rules, expected from EPA soon, on reducing greenhouse gas emissions from existing power plants.

Power companies have “ambitious plans” to add CCUS to power plants, estimated to cause 25% of U.S. CO2 emissions. As a result, the power sector “needs CCUS in its toolkit,” said DOE Office of Fossil Energy and Carbon Management Assistant Secretary Brad Crabtree. Successful pilots and demonstrations “will add to investor confidence and lead to more deployment” to provide dispatchable clean energy, including emerging CO2-to-electricity approaches for power system reliability after 2030,| he added.

But environmentalists and others insist potentially cost-prohibitive CCUS infrastructure, including CO2 storage hub initiatives, must still prove itself effective under rigorous and transparent federal oversight.

“The vast majority of long-term U.S. power sector needs can be met without fossil generation, and better options are being deployed and in development,” Sierra Club Senior Advisor, Strategic Research and Development, Jeremy Fisher, said, pointing to carbon-free electricity investments gaining momentum in the market. CCUS “may be needed, but without better guardrails, power sector abuses of federal funding could lead to increased emissions and stranded fossil assets,” he added.

New DOE CCUS project grants, an increased $85 per metric ton, or tonne, federal 45Q tax credit, and the forthcoming EPA power plant carbon rules and the federal coal plan will do for CCUS what similar policies did for renewables, advocates and opponents agreed. But controversial past CCUS performance and tax credit abuses must be avoided with transparent reporting requirements for CO2 capture, opponents added.
