GE Global Research, the technology development arm of the General Electric Company, announced a battery-free, multi-detection radio-frequency identification (RFID) sensing platform that could enable a wide range of low cost wireless sensing products in healthcare, security, food packaging, water treatment and pollution prevention.

GE's unique RFID sensors are built on traditional RFID tags.

This “first-of-its-kind” sensing platform, in which a single sensor can provide a highly selective response to multiple chemicals under variable conditions, operates without a battery. GE’s sensor technology overcomes limitations in today’s sensors such as inadequate response selectivity and the need for an on-board power source. Without a battery, new sensors can be designed to be smaller than a penny and manufactured at very low cost. This could enable many exciting product applications, including:

• New security sensors that more effectively can detect dangerous chemical and biological threats;

• In-the-field water purification monitoring, checking for water impurities;

• Food and beverage safety monitoring, measuring the freshness of goods in transport or that are stored in the refrigerator at home;

• Portable vaccine manufacturing, ensuring the purity of a vaccine manufactured on-site during an emergency response to a flu outbreak or other potential pandemic;

• Emissions monitoring at power plants.

Radislav Potyrailo, a principal scientist at GE Global Research who leads this multidisciplinary wireless sensing development team, said, “We believe GE’s battery-free wireless sensing platform will be a game-changer across many product platforms in healthcare, security, water and pollution prevention, to name a few. Without the need for batteries, we can make sensors that are much smaller in size and at substantially reduced costs. These attributes, combined with the sensors’ highly selective chemical and bio sensing capabilities, provide new breakthrough sensing opportunities that will open the door to many new, innovative applications.”

Potyrailo added, "Because these sensors can be made at such low cost, they also can be made for one-time use. Similar to how your groceries get scanned for a price, imagine pointing a handheld sensor reader at a milk carton or packaged food to see whether it has been spoiled. This is just one of the new applications you can begin to consider with disposable, low cost multi-detection RFID sensors."

These new RFID sensors use a conventional RFID tag, but are coated with a chemically or biologically sensitive film. The sensor reader can obtain several varied responses, which allows the sensor to identify and measure individual chemicals in different mixtures and variable conditions. GEÂ’s sensors can detect trace concentrations of toxic gases such as toxic industrial chemicals (TICs), volatile organic compounds (VOCs), and chemicals in liquids.

To operate without batteries, the power is obtained wirelessly from the sensor reader. The reader activates the sensor antenna and the RFID chip and collects several response data parameters. The measurement of these parameters provides the ability to selectively detect different chemicals with an individual sensor.

The development of GEÂ’s novel wireless sensing platform illustrates the power of GE technology to leverage multiple areas of technical expertise from across many disciplines represented at GEÂ’s Global Research Center. A multidisciplinary team comprised of analytical chemists, RF engineers, polymer scientists, and microfabrication engineers contributed to the development of this new platform.

Electricity Demand In The Time Of COVID-19

COVID-19 Impact on U.S. Power Demand shows falling electricity load, lower wholesale prices, and resilient utilities in competitive markets, with regional differences tied to weather, renewable energy, stay-at-home orders, and hedging strategies.

 

Key Points

It outlines reduced load and prices, while regulatory design and hedging support utility stability across regions.

✅ Load down in NY, New England, PJM; weather drives South up.

✅ Wholesale prices fall 8-10% in key markets.

✅ Decoupling, contracts, hedging support utility earnings.

 

On March 27, Bloomberg New Energy Finance (BNEF) released a report on electricity demand and wholesale market prices impact from COVID-19 fallout. The model compares expected load based largely on weather with actual observed electricity demand changes.

So far, the hardest hit power grid is New York, with load down 7 and prices off by 10 percent. That’s expected, given New York City is the current epicenter of the US health crisis.

Next is New England, with 5 percent lower demand and 8 percent reduced wholesale prices for the week from March 19-25. BNEF says the numbers could go higher following advisories and orders issued March 24 for some 70 percent of the region’s population to stay at home.

Demand on the biggest grid in the US, the PJM (Pennsylvania/Jersey/Maryland), is 4 percent lower, with prices dropping 8 percent, as recent capacity auction payouts fell sharply. BNEF believes there will be more impact as stay at home orders are ramped up in several states.

California’s power demand for March 19-25 was 5 percent below what BNEF’s model expects without COVID-19 impact. That reflects a full week of stay-at-home orders from Governor Newsom issued March 19.

Health officials in Los Angeles and elsewhere expect a spike in COVID-19 cases in coming weeks. But BNEF’s model now actually projects rising electricity load for the state, due to what it calls "freakishly mild weather a year ago."

Rounding out the report, power demand is up for a band of southern states stretching from Florida to the desert Southwest, with weather more than offsetting public response to COVID-19 so far. BNEF says the Northwest’s grid "has not yet been highly impacted," while the Southeast is "generally in line" with pre-virus expectations.

Clearly, all of this data can change quickly and radically. Only California and New York are currently in full shutdown mode. Following them are New England (70 percent), the Midwest (65 percent), Texas (50 percent), PJM (50 percent) and the Northwest (50 percent).

In contrast, only small parts of Florida, the Southeast and Southwest are restricting movement. That could mean a big future increase for shut-ins, with heightened risks of electricity shut-offs that burden households and a corresponding impact on power demand.

Also, weather will play a major role on what happens to actual electricity demand, just as it always does. A very hot summer, for example, could offset virus-related shut-ins, just as it apparently is now in states like Texas. And it should be pointed out that regions vary widely by exposure to recession-sensitive sources of demand, such as heavy industry.

Most important for investors, however, is the built in protection US utility earnings enjoy from declining power demand, even amid broader energy crisis pressures facing the sector. For one thing, US power grids in California, ERCOT (Texas), MISO (Midwest), New England, New York and PJM have wholesale power markets, where producers compete for sales and the lowest bidder sets the price.

In those states, most regulated utilities don’t produce power at all. In fact, companies’ revenue is decoupled entirely from demand in California, as well as much of New England. In the roughly three-dozen states where utilities still operate as integrated monopolies, demand does affect revenue, and in many regions flat electricity demand already persists. But the cost of electricity is passed through directly to customers, whether produced or purchased.

A number of US electric companies have invested in renewable energy facilities as part of broader electrification trends nationwide. These sell their output under long-term contracts primarily with other utilities and government entities.

This isn’t a risk free business: For the past year, generators selling electricity to bankrupt PG&E Corp (PCG) have had their cash trapped at the power plant level as surety for lenders. But even PG&E has honored its contracts. And with states continuing aggressive mandates for renewable energy adoption, growth doesn’t appear at risk to COVID-19 fallout either.

The wholesale price of power from natural gas, coal and many nuclear plants was already sliding before COVID-19, due to renewables adoption and low natural gas prices, even as coal and nuclear disruptions raise reliability concerns. But here too, big producers like Exelon Corp (EXC) and Vistra Energy (VST) have employed aggressive price hedging near term, with regulated utilities and retail businesses protecting long-term health, respectively.

Bottom line: It’s early days for the COVID-19 crisis and much can still change. But so far at least, the US power industry is absorbing the blow of reduced demand, just as it’s done in previous crises.

That means future selloffs in the ongoing bear market are buying opportunities for best in class electric utilities, not a reason to sell. For top candidates, see the Conrad’s Utility Investor Portfolios and Dream Buy List in the March issue.

BC Hydro completes major milestone on Site C transmission line work

Site C 500 kV transmission lines strengthen the BC Hydro grid, linking the new substation and Peace Canyon via a 75 kilometre right-of-way to deliver clean energy, with 400 towers built and both circuits energized.

 

Key Points

High-voltage lines connecting Site C substation to the BC Hydro grid, delivering clean energy via Peace Canyon.

✅ Two 75 km circuits between Site C and Peace Canyon

✅ Connect new 500 kV substation to BC Hydro grid

✅ Over 400 towers built along existing right-of-way

 

The second and final 500 kilovolt, 75 kilometre transmission line on the Site C project, which has faced stability questions in recent years, has been completed and energized.

With this milestone, the work to connect the new Site C substation to the BC Hydro grid, amid treaty rights litigation that has at times shaped schedules, is complete. Once the Site C project begins generating electricity, much like when the Maritime Link first power flowed between Newfoundland and Nova Scotia, the transmission lines will help deliver clean energy to the rest of the province.

The two 75 kilometre transmission lines run along an existing right-of-way between Site C and the Peace Canyon generating station, a route that has seen community concerns from some northerners. The project’s first 500 kilovolt, 75 kilometre transmission line – along with the Site C substation – were both completed and energized in the fall of 2020.

BC Hydro awarded the Site C transmission line construction contract to Allteck Line Contractors Inc. (now Allteck Limited Partnership) in 2018. Since construction started on this part of the project in summer 2018, crews have built more than 400 towers and strung lines, even as other interties like the Manitoba-Minnesota line have faced scheduling uncertainty, over a total of 150 kilometres.

The two transmission lines are a major component of the Site C project, comparable to initiatives such as the New England Clean Power Link in scale, which also consists of the new 500 kilovolt substation and expanding the existing Peace Canyon 500 kilovolt gas-insulated switchgear to incorporate the two new 500 kilovolt transmission line terminals.

Work to complete three other 500 kilovolt transmission lines that will span one kilometre between the Site C generating station and Site C substation, similar to milestones on the Maritime Link project, is still underway. This work is expected to be complete in 2023.

Georgia Power warns customers of scams during pandemic

Georgia Power Scam Alert cautions customers about phone scams, phishing, and fraud during COVID-19, urging identity verification, refusal of prepaid card payments, use of Authorized Payment Locations, and customer service contact to avoid disconnection threats.

 

Key Points

A warning initiative on fraud, phone scams, and safe payments to protect Georgia Power customers during COVID-19.

✅ Never pay by phone with prepaid cards or credit card numbers.

✅ Verify employee ID, badge, and marked vehicle before opening.

✅ Call 888-660-5890 or use Authorized Payment Locations only.

 

With continued reports of attempted scams and fraud, including holiday scam warnings in other regions, by criminals posing as Georgia Power employees during the COVID-19 pandemic, the company reminds customers to be aware and follow simple tips to avoid becoming a victim.

Customers should beware of phone calls demanding payment via phone to avoid pandemic-related electricity shut-offs and penalties.

In other regions, Texas utilities waived fees to support customers during the pandemic.

Last month, Georgia Power and the Georgia Public Service Commission extended the suspension of disconnections due to the impact of the pandemic on customers. In addition, the company will never ask for a credit card or pre-paid debit card number over the phone. The company will also never send employees into the field to collect payment in person or ask a customer to pay anywhere other than an Authorized Payment Location.

Similarly, Gulf Power offered a one-time bill decrease to ease customer costs.

If an account becomes past due, Georgia Power will contact the customer via a pre-recorded message to the primary account telephone number or by letter requesting that the customer call to discuss the account, including available June bill reductions where applicable.

If a customer receives a suspicious call from someone claiming to be from Georgia Power and demanding payment to avoid disconnection despite utility moratoriums on shutoffs, the customer should hang up and contact the company's customer service line at 888-660-5890.

If an employee needs to visit a customer's home or business for a service-related issue, they will be in uniform and present a badge with a photo, their name and the company's name and logo. They will also be in a vehicle marked with the company's logo.

During the pandemic, visiting a customer's home or business will be even less likely, so identity verification should be completed before opening the door to anyone.

Georgia Power continues to work with law enforcement agencies throughout the state to identify and prosecute criminals who pose as Georgia Power employees to defraud customers.

Transmission constraints impede incremental Quebec-to-US power deliveries

Hydro-Québec Northeast Clean Energy Transmission delivers surplus hydropower via HVDC interconnections to New York and New England, leveraging long-term contracts and projects like CHPE and NECEC to support carbon-free goals, GHG cuts, and grid reliability.

 

Key Points

An initiative to expand HVDC links for Quebec hydropower exports, aiding New York and New England decarbonization.

✅ 37,000 MW hydro capacity enables firm, low-carbon exports

✅ Targets NY and NE via CHPE, NECEC, and upgraded interfaces

✅ Backed by long-term PPAs to reduce merchant transmission risk

 

With roughly 37,000 MW of installed hydro power capacity, Quebec has ample spare capacity that it would like to deliver into Northeastern US markets where ambitious clean energy goals have been announced, but expanding transmission infrastructure is challenging.

Register Now New York recently announced a goal of receiving 100% carbon-free energy by 2040 and the New England states all have ambitious greenhouse gas reduction goals, including a Massachusetts law requiring GHG emissions be 80% below 1990 levels by 2050.

The province-owned company, Hydro Quebec, supplies power to the provinces of Quebec, Ontario and New Brunswick in particular, as well as sending electricity directly into New York and New England. The power transmission interconnections between New York and New England have reached capacity and in order to increase export volumes into the US, "we need to build more transmission infrastructure," Gary Sutherland, relationship manager in business development, recently said during a presentation to reporters in Montreal.

 

TRANSMISSION OPTIONS

Hydro Quebec is working with US transmission developers, electric distribution companies, independent system operators and state government agencies to expand that transmission capacity in order to delivery more power from its hydro system to the US, as the province has closed the door on nuclear power and continues to prioritize hydropower, Sutherland said.

The company is looking to sign long-term power supply contracts that could help alleviate some of the investment risk associated with these large infrastructure projects.

"It`s interesting to recall that in the 1980s, two decade-long contracts paved the way for construction of Phase II of the multi-terminal direct-current system (MTDCS), a cross-border line that delivers up to 2,000 MW from northern Quebec to New England," Hydro Quebec spokeswoman Lynn St-Laurent said in an email.

Long-term prices have been persistently low since 2012, following the shale gas boom and the economic decline in 2008-2009, St-Laurent said. "As such, investment risks are too high for merchant transmission projects," she said.

Northeast power market fundamentals "remain strong for long-term contracts," on transmission projects or equipment upgrades that can deliver clean power from Quebec and "help our neighbors reach their ambitious clean energy goals," St-Laurent said.

 

NEW ENGLAND

In March 2017 an HQ proposal was selected by Massachusetts regulators to supply 9.45 TWh of firm energy to be delivered for 20 years. HQ`s proposal consisted of hydro power supply and possible transmission scenarios developed in conjunction with US partners.

The two leading options include a route through New Hampshire called Northern Pass and New England Clean Energy Connect through Maine.

The New Hampshire Site Evaluation Committee in March 2018 voted unanimously to deny approval of the $1.6 billion Northern Pass Transmission project, which is a joint venture between HQ and Eversource Energy`s transmission business. Eversource has been fighting the decision, with the New Hampshire Supreme Court accepting the company`s appeal of the NHSEC decision in October.

Briefs are being filed and oral arguments are likely to begin late spring or early summer, spokesman William Hinkle said in an email Tuesday.

After the Northern Pass permitting delay, Massachusetts chose the New England Clean Energy Connect project, which is a projected 1,200 MW transmission line, with 1,090 MW contracted to Massachusetts, leaving 110 MW for use on a merchant basis, according to St-Laurent.

NECEC is a joint venture between HQ and Central Maine Power, which is a subsidiary of Avangrid, a company affiliated with Spain`s Iberdrola. The NECEC project has received opposition from some environmental groups and still needs several state and federal permits.

 

NEW YORK

"The 5% of New York`s load that we furnish year in and year out ... is mostly going into the north of the state, it`s not coming down here," Sutherland said during a discussion at Pace University in New York City in 2017.

One potential project moving through the permitting phase, is the $2.2 billion, 1,000-MW Champlain Hudson Power Express transmission line being pursued by Transmission Developers -- a Blackstone portfolio company -- that would transport power from Quebec to Queens, New York.

Under New York`s proposed Climate Leadership Act which calls for the 100% carbon-free energy goal, renewable generation eligibility would be determined by the Public Service Commission. The PSC did not respond to a question about whether hydro power from Quebec is being considered as a potential option for meeting the state`s clean energy goal.

BNEF Report: Wind and Solar Will Provide 50% of Electricity in 2050

BNEF 2019 New Energy Outlook projects surging renewable energy demand, aggressive decarbonization, wind and solar cost declines, battery storage growth, coal phase-out, and power market reform to meet Paris Agreement targets through 2050.

 

Key Points

Bloomberg's NEO 2019 forecasts power demand, renewables growth, and decarbonization pathways through 2050.

✅ Predicts wind/solar to ~50% of global electricity by 2050

✅ Foresees coal decline; Asia transitions slower than Europe

✅ Calls for power market reform and battery integration

 

In a report that examines the ways in which renewable energy demand is expected to increase, Bloomberg New Energy Finance (BNEF) finds that “aggressive decarbonization” will be required beyond 2030 to meet the temperature goals of the Paris Agreement on climate change.

Focusing on electricity, BNEF’s 2019 New Energy Outlook (NEO) predicts a 62% increase in global power demand, leading to global generating capacity tripling between now and 2050, when wind and solar are expected to make up almost 50% of world electricity, as wind and solar gains indicate, due to decreasing costs.

The report concludes that coal will collapse everywhere except Asia, and, by 2032, there will be more wind and solar electricity than coal-fired electricity. It forecasts that coal’s role in the global power mix will decrease from 37% today, as renewables surpass 30% globally, to 12% by 2050 with the virtual elimination of oil as a power-generating source.

Highlighting regional differences, the report finds that:

Western European economies are already on a strong decarbonization path due to carbon pricing and strong policy support, with offshore wind costs dropping bolstering progress;

by 2040, renewables will comprise 90% of the electricity mix in Europe, with wind and solar accounting for 80%;

the US, with low-priced natural gas, and China, with its coal-fired plants, will transition more slowly even as 30% from wind and solar becomes feasible; and

China’s power sector emissions will peak in 2026 and then fall by more than half over the next 20 years, as solar PV growth accelerates, with wind and solar increasing from 8% to 48% of total electricity generation by 2050.

Power markets must be reformed to ensure wind, solar and batteries are properly remunerated for their contributions to the grid.

The 2019 report finds that wind and solar now represent the cheapest option for adding new power-generating capacity in much of the world, amid record-setting momentum, which is expected to attract USD 13.3 trillion in new investment. While solar, wind, batteries and other renewables are expected to attract USD 10 trillion in investment by 2050, the report warns that curbing emissions will require other technologies as well.

Speaking about the report, Matthias Kimmel, NEO 2019 lead analyst, said solar photovoltaic modules, wind turbines and lithium-ion batteries are set to continue on aggressive cost reduction curves of 28%, 14% and 18%, respectively, for every doubling in global installed capacity. He explained that by 2030, energy generated or stored and dispatched by these technologies will undercut electricity generated by existing coal and gas plants.

To achieve this level of transition and decarbonization, the report stresses, power markets must be reformed to ensure wind, solar and batteries are “properly remunerated for their contributions to the grid.”

Additionally, the 2019 NEO includes a number of updates such as:

  • new scenarios on global warming of 2°C above preindustrial levels, electrified heat and road transport, and an updated coal phase-out scenario;
  • new sections on coal and gas power technology, the future grid, energy access, and costs related to decarbonization technology such as carbon capture and storage (CCS), biogas, hydrogen fuel cells, nuclear and solar thermal;
  • sub-national results for China;
  • the addition of commercial electric vehicles;
  • an expanded air-conditioning analysis; and
  • modeling of Brazil, Mexico, Chile, Turkey and Southeast Asia in greater detail.

Every year, the NEO compares the costs of competing energy technologies, informing projections like US renewables at one-fourth in the near term. The 2019 report brought together 65 market and technology experts from 12 countries to provide their views on how the market might evolve.

Washington AG Leads Legal Challenge Against Trump’s Energy Emergency

Washington-Led Lawsuit Against Energy Emergency challenges President Trump's executive order, citing state rights, environmental reviews, permitting, and federal overreach; coalition argues record energy output undermines emergency claims in Seattle federal court.

 

Key Points

Multistate suit to void Trump's energy emergency, alleging federal overreach and weakened environmental safeguards.

? Challenges executive order's legal basis and scope

? Claims expedited permitting skirts environmental reviews

? Seeks to halt emergency permits for non-emergencies

 

In a significant legal move, Washington State Attorney General Nick Brown has spearheaded a coalition of 15 states in filing a lawsuit against President Donald Trump's executive order declaring a national energy emergency. The lawsuit, filed in federal court in Seattle on May 9, 2025, challenges the legality of the emergency declaration, which aims to expedite permitting processes for fossil fuel projects in pursuit of an energy dominance vision by bypassing key environmental reviews.

Background of the Energy Emergency Declaration

President Trump's executive order, issued on January 20, 2025, asserts that the United States faces an inadequate and unreliable energy grid, particularly affecting the Northeast and West Coast regions. The order directs federal agencies, including the Army Corps of Engineers and the Department of the Interior, to utilize "any lawful emergency authorities" to facilitate the development of domestic energy resources, with a focus on oil, gas, and coal projects. This includes expediting reviews under the Clean Water Act, Endangered Species Act, the National Environmental Policy Act, and the National Historic Preservation Act, potentially reducing public input and environmental oversight.

Legal Grounds for the Lawsuit

The coalition of states, led by Washington and California, argues that the emergency declaration is an overreach of presidential authority, echoing disputes over the Affordable Clean Energy rule in federal courts. They contend that U.S. energy production is already at record levels, and the declaration undermines state rights and environmental protections. The lawsuit seeks to have the executive order declared unlawful and to halt the issuance of emergency permits for non-emergency projects. 

Implications for Environmental Protections

Critics of the energy emergency declaration express concern that it could lead to significant environmental degradation. By expediting permitting processes, including geothermal permitting, and reducing public participation, the order may allow projects to proceed without adequate consideration of their impact on water quality, wildlife habitats, and cultural resources. Environmental advocates argue that such actions could set a dangerous precedent, enabling future administrations to bypass essential environmental safeguards under the guise of national emergencies, even as the EPA advances new pollution limits for coal and gas plants to address the climate crisis.

Political and Legal Reactions

The Trump administration defends the executive order, asserting that the president has the authority to declare national emergencies and that the energy emergency is necessary to address perceived deficiencies in the nation's energy infrastructure and potential electricity pricing changes debated by industry groups. However, legal experts suggest that the broad application of emergency powers in this context may face challenges in court. The outcome of the lawsuit could have significant implications for the balance of power between state and federal authorities, as well as the future of environmental regulations in the United States.

The legal challenge led by Washington State Attorney General Nick Brown represents a critical juncture in the ongoing debate over energy policy and environmental protection. As the lawsuit progresses through the courts, it will likely serve as a bellwether for future conflicts between state and federal governments regarding the scope of executive authority and the preservation of environmental standards, amid ongoing efforts to expand uranium and nuclear energy programs nationwide. The outcome may set a precedent for how national emergencies are declared and managed, particularly concerning their impact on state governance and environmental laws.
