It was only when Stephen Fopiano noticed the morning's newspapers were missing that he looked around and saw something unusual, even for Harvard Square.

"There was some serious flames coming out of there," Fopiano said as he pointed to the intersection of Dunster Street and Massachusetts Avenue. "There was a lot of flames."

Fopiano was one of dozens who witnessed a persistent fire that sent flames up to 15 feet in the air, following a string of manhole explosions early May 2.

In all, four NStar manholes exploded beginning around 2:30 a.m., forcing partial closure of one of Cambridge's most famous pieces of real estate for about eight hours to both pedestrian and car traffic. MBTA Red Line service continued without interruption, and some bus service was rerouted.

Caroline Allen, an NStar spokeswoman, said crews were working to repair the burned and soaked wiring all weekend, hoping to avoid disruptions of the 24th annual Mayfair, which was held in Harvard Square May 4.

Allen said the cause of the blaze remains under investigation.

Deputy Fire Chief James F. Burns, a department spokesman, said the explosions occurred in three manholes running along the red brick sidewalk in the square and in a fourth at the corner of Dunster and Massachusetts Avenue.

He said that after the initial explosion, lubricating oil used in electrical transmissions caught fire, causing the heavy flames that poured out of the manhole.

Once certain that the problem was limited to the four manholes in the square, Burns said, firefighters allowed the blaze to burn itself out and then sprayed water to cool down the electrical conduit tunnel, so utility workers could begin repairs.

Harvard University classes were not disrupted, but Holyoke Center was closed. Harvard's infirmary was evacuated, and one student was transferred to a Cambridge hospital by ambulance, a Harvard spokesman said.

There were no injuries from the fire, and no substantial damage was reported to businesses in Harvard Square, officials said.

The cable malfunction was akin to a house blowing a fuse, but on a much larger scale, NStar's Allen said. The initial blast knocked out power to 700 customers, but service was fully restored by 12:30 p.m.

Texas Utilities back out of deal to create smart home electricity networks

Smart Meter Texas real-time pricing faces rollback as utilities limit on-demand reads, impacting demand response, home area networks, ERCOT wholesale tracking, and thermostat automation, reducing efficiency gains promised through deregulation and smart meter investments.

 

Key Points

A plan linking smart meters to ERCOT prices, enabling near real-time usage alignment and automated demand response.

✅ Twice-hourly reads miss 15-minute ERCOT price spikes.

✅ Less than 1% of 7.3M meters use HAN real-time features.

✅ Limits hinder automation for HVAC, EV charging, and pool pumps.

 

Utilities made a promise several years ago when they built Smart Meter Texas that they’d come up with a way for consumers to monitor their electricity use in real time. But now they’re backing out of the deal with the approval of state regulators, leaving in the lurch retail power companies that are building their business model on the promise of real time pricing and denying consumers another option for managing their electricity costs.

Texas utilities collected higher rates to finance the building of a statewide smart meter network that would allow customers to track their electricity use and the quickly changing prices on wholesale power markets almost as they happened. Some retailers are building electricity plans around this promise, providing customers with in-home devices that would eventually track pricing minute-by-minute and allow them to automatically turn down or shut off air conditioners, pool pumps and energy sucking appliances when prices spiked on hot summer afternoons and turn them back on when they prices fell again.

The idea is to help save consumers money by allowing them to shift their electricity consumption to periods when power is cheaper, typically nights and weekends, even as utility revenue in a free-power era remains a debated topic.

“We’re throwing away a large part of (what) ratepayers paid for,” said John Werner, CEO of GridPlus Texas, one of the companies offering consumers a real-time pricing plan that is scheduled to begin testing next month. “They made the smart meters dumb meters.”

When Smart Meter Texas was launched a decade ago by a consortium of the state’s biggest utilities, it was considered an important part of deregulation. The competitive market for electricity held the promise that consumers would eventually have the technology to control their electricity use through a home area network and cut their power bills.

Regulators and legislators also were enticed by the possibility of making the electric system more efficient and relieving pressure on the power grid as consumers responded to high prices and cut consumption when temperatures soared, with ongoing discussions about Texas grid reliability informing policy choices.

One study found that smart meters coupled with smart real time consumption monitors could reduce electricity use between 3 percent and 5 percent, according to Call Me Power, a website sponsored by the European electricity price shopping service Selectra.

But utilities complained that the home area network devices were expensive to install and not used very often, and, with flat electricity demand weighing on growth, they questioned further investment. CenterPoint manager Esther Floyd Kent filed an affidavit with the commission in May that it costs the utility about $30,000 annually to support the network devices, plus maintenance.

Over a six-year period, CenterPoint paid $124,500, or about $20,000 a year, to maintain the system. As of April, there were only 4,067 network devices in CenterPoint’s service area, meaning the utility pays about $30.70 each year to maintain each device.

Centerpoint last year generated $9.6 billion in revenues and earned a $1.8 billion profit, according to its financial filings. CenterPoint officials did not respond to requests for comment.

Other utilities that are part of the Smart Meter consortium also complained to the Public Utility Commission that, up to now, the system hasn’t developed. All told, Texas has 7.3 million meters connected to Smart Meter Texas, but less than 1 percent are using the networking functions to track real-time prices and consumption, according to the testimony of Donny R. Helm, director of technology strategy and architecture for the state’s largest utility Oncor Electric Delivery Co. in Dallas.

The isssue was resolved recently through a settlement agreement that limits on-demand readings to twice an hour that Smart Meter Texas must provide customers. The price of power changes every 15 minutes, so a twice an hour reading may miss some price spikes.

The Public Utility Commission signed off on the deal, and so did several other groups including several retail electricity providers and the Office of Public Utility Counsel which represents residential customers and small businesses.

Michele Gregg, spokeswoman for the Public Utility Counsel, testified in December that the consumer advocate supported the change because widespread use of the networks never materialized. Catherine Webking, an Austin lawyer who represents the Texas Energy Association for Marketers, a group of retail electric providers, said she believes the deal was a reasonable resolution of providing the benefits of Smart Meter Texas while not incurring too much cost.

But Griddy, an electricity provider that offers customers the opportunity to pay wholesale power prices, which also issued a plea to customers during a price surge, said the state hasn’t given the smart-meter networks a chance and could miss out on its potential. Griddy was counting on the continued adoption of real time pricing as the next step for customers wanting to control their electricity costs.

Right now, Griddy sends out price alerts from the grid operator Electric Reliability Council of Texas so businesses like hotels can run washers and dryers when electricity prices are cheapest. But the company was counting on a smart-meter program that would allow customers to track wholesale prices and manage consumption themselves, making Griddy’s offerings attractive to more people.

Wholesale prices are generally cheaper than retail prices, but they can fluctuate widely, especially when the Texas power grid faces another crisis during extreme weather. Last year, wholesale prices averaged less than 3 cents per kilowatt hour, much lower than than retail rates that now are running above 11 cents, but they can spike at times of high demand to as much as $9 a kilowatt hour.

What customers want is to be able to use energy when it’s cheapest, said Greg Craig, Griddy’s CEO, and they want to do it automatically. They want to be able to program their thermostat so that if the price rises they can shut off their air conditioning and if the price falls, they can charge their electric-powered vehicle.

Griddy customers may still save money even without real time data, he said. But they won’t be able to see their usage in real time or see how much they’re spending.

“The big utilities have big investments in the existing way and going to real time and more transparency isn’t really in their best interest,” said Craig.

DOE Announces $28M Award for Wind Energy

DOE Wind Energy Funding backs 13 R&D projects advancing offshore wind, distributed energy, and utility-scale turbines, including microgrids, battery storage, nacelle and blade testing, tall towers, and rural grid integration across the United States.

 

Key Points

DOE Wind Energy Funding is a $28M R&D effort in offshore, distributed, and utility-scale wind to lower cost and risk.

✅ $6M for rural microgrids, storage, and grid integration.

✅ $7M for offshore R&D, nacelle and long-blade testing.

✅ Up to $10M demos; $5M for tall tower technology.

 

The U.S. Department of Energy announced that in order to advance wind energy in the U.S., 13 projects have been selected to receive $28 million. Project topics focus on technology development while covering distributed, offshore wind growth and utility-scale wind found on land.

The selections were announced by the DOE’s Assistant Secretary for the Office of Energy Efficiency and Renewable Energy, Daniel R. Simmons, at the American Wind Energy Association Offshore Windpower Conference in Boston, as New York's offshore project momentum grows nationwide.

 

Wind Project Awards

According to the DOE, four Wind Innovations for Rural Economic Development projects will receive a total of $6 million to go toward supporting rural utilities via facilitating research drawing on U.K. wind lessons for deployment that will allow wind projects to integrate with other distributed energy resources.

These endeavors include:

Bergey WindPower (Norman, Oklahoma) working on developing a standardized distributed wind/battery/generator micro-grid system for rural utilities;

Electric Power Research Institute (Palo Alto, California) working on developing modeling and operations for wind energy and battery storage technologies, as large-scale projects in New York progress, that can both help boost wind energy and facilitate rural grid stability;

Iowa State University (Ames, Iowa) working on optimization models and control algorithms to help rural utilities balance wind and other energy resources; and

The National Rural Electric Cooperative Association (Arlington, Virginia) providing the development of standardized wind engineering options to help rural-area adoption of wind.

Another six projects are to receive a total of $7 million to facilitate research and development in offshore wind, as New York site investigations advance, with these projects including:

Clemson University (North Charleston, South Carolina) improving offshore-scale wind turbine nacelle testing via a “hardware-in-the-loop capability enabling concurrent mechanical, electrical and controller testing on the 7.5-megawatt dynamometer at its Wind Turbine Drivetrain Testing Facility to accelerate 1 GW on the grid progress”; and

The Massachusetts Clean Energy Center (Boston) upgrading its Wind Technology Testing Center to facilitate structural testing of 85- to 120-meter-long (roughly 278- to 393-foot-long) blades, as BOEM lease requests expand, among other projects.

Additionally, two offshore wind technology demonstration projects will receive up to $10 million for developing initiatives connected to reducing wind energy risk and cost. One last project will also be granted $5 million for the development of tall tower technology that can help overcome restrictions associated with transportation.

“These projects will be instrumental in driving down technology costs and increasing consumer options for wind across the United States as part of our comprehensive energy portfolio,” said Simmons.

British Columbia Halts Further Expansion of Self-Driving Vehicles

BC Autonomous Vehicle Ban freezes new driverless testing and deployment as BC develops a regulatory framework, prioritizing safety, liability clarity, and road sharing with pedestrians and cyclists while existing pilot projects continue.

 

Key Points

A moratorium pausing new driverless testing until a safety-first regulatory framework and clear liability rules exist.

✅ Freezes new AV testing and deployment provincewide

✅ Current pilot shuttles continue under existing approvals

✅ Focus on safety, liability, and road-user integration

 

British Columbia has halted the expansion of fully autonomous vehicles on its roads. The province has announced it will not approve any new applications for testing or deployment of vehicles that operate without a human driver until it develops a new regulatory framework, even as it expands EV charging across the province.


Safety Concerns and Public Questions

The decision follows concerns about the safety of self-driving vehicles and questions about who would be liable in the event of an accident. The BC government emphasizes the need for robust regulations to ensure that self-driving cars and trucks can safely share the road with traditional vehicles, pedestrians, and cyclists, and to plan for infrastructure and power supply challenges associated with electrified fleets.

"We want to make sure that British Columbians are safe on our roads, and that means putting the proper safety guidelines in place," said Rob Fleming, Minister of Transportation and Infrastructure. "As technology evolves, we're committed to developing a comprehensive framework to address the issues surrounding self-driving technology."


What Does the Ban Mean?

The ban does not affect current pilot projects involving self-driving vehicles that already operate in BC, such as limited shuttle services and segments of the province's Electric Highway that support charging and operations.


Industry Reaction

The response from industry players working on autonomous vehicle technology has been mixed, amid warnings of a potential EV demand bottleneck as adoption ramps up. While some acknowledge the need for clear regulations, others express concern that the ban could stifle innovation in the province.

"We understand the government's desire to ensure safety, but a blanket ban risks putting British Columbia behind in the development of this important technology," says a spokesperson for a self-driving vehicle start-up.


Debate Over Self-Driving Technology

The BC ban highlights a larger debate about the future of autonomous vehicles. While proponents point to potential benefits such as improved safety, reduced traffic congestion, and increased accessibility, and national policies like Canada's EV goals aim to accelerate adoption, critics raise concerns about liability, potential job losses in the transportation sector, and the ability of self-driving technology to handle complex driving situations.


BC Not Alone

British Columbia is not the only jurisdiction grappling with the regulation of self-driving vehicles. Several other provinces and states in both Canada and the U.S. are also working to develop clear legal and regulatory frameworks for this rapidly evolving technology, even as studies suggest B.C. may need to double its power output to fully electrify road transport.


The Road Ahead

The path forward for fully autonomous vehicles in BC depends on the government's ability to create a regulatory framework that balances safety considerations with fostering innovation, and align with clean-fuel investments like the province's hydrogen project to support zero-emission mobility.  When and how that framework will materialize remains unclear, leaving the future of self-driving cars in the province temporarily uncertain.

NL Consumer Advocate says 18% electricity rate hike 'unacceptable'

Newfoundland and Labrador electricity rate hike examines a proposed 18.6% increase under the PUB's Rate Stabilization Plan, driven by oil prices at Holyrood, with Consumer Advocate concerns over rate shock and use of RSP balances.

 

Key Points

A proposed 18.6% July 2017 increase under the RSP, driven by oil prices, now under PUB review for potential mitigation.

✅ PUB flags potential rate shock from proposed adjustment

✅ RSP balances cited to offset increases without depleting fund

✅ Oil-fired Holyrood volatility drives fuel cost uncertainty

 

How much of a rate hike is reasonable for users of electricity in Newfoundland and Labrador?

That's a question before the Public Utilities Board (PUB) as it examines an application by Newfoundland and Labrador Hydro, which could see consumers pay up to 18.6 per cent more as of July 1, reflecting regional pressures seen in Nova Scotia, where regulators approved a 14% rate hike earlier this year.

"The estimated rate increase for July 2017 is such a significant increase that it may be argued that it would cause rate shock," said the PUB, asking the company to revise its application.

NL Hydro said the price adjustment is part of what happens every year through the Rate Stabilization Plan (RSP), which is used to offset the ups and downs of oil prices.

"The cost of fuel is volatile and as long as we rely on oil-fired generation at Holyrood, customers will continue to be impacted by this electricity price uncertainty," said the company in a statement to CBC News.

It noted that customers received a break from RSP adjustments in 2015 and 2016, even as costs from the Muskrat Falls project begin to be reflected.

The PUB noted that under the rate stabilization plan, prices have gone up or down by about 10 per cent in the past.

The regulatory board said the impact of the latest request would be a 27.6 per cent hike to Newfoundland Power, with "an estimated average end customer impact of 18.6 per cent."

Hydro's estimates are based on an average price for oil of $81.40 per barrel from July 2017 to June 2018, according to the PUB.

 

'Unacceptable' burden: Consumer Advocate

"To burden ratepayers with an 18 per cent rate increase is unacceptable," said Consumer Advocate Dennis Browne, echoing pushback in Nova Scotia, where the premier urged regulators to reject a 14% hike at the time.

Browne is arguing that there is money in the RSP to reduce the proposed increase, including the possibility of a lump-sum bill credit for customers.

"These ratepayer balances — which, according to NL Power, totals $77.4 million — are not the property of Hydro," he wrote in a letter to the PUB.

"No utility has the right to squirrel away ratepayers' money to be used by that utility for some future purpose. The Board has jurisdiction over those balances," Browne said.

Browne also wants the RSP overhauled so that it can be applied to price fluctuations every quarter, as opposed to annually.

Hydro has expressed concern that depleting the rate stabilization fund would lead to other, more significant, rate increases in the future.

It said several alternatives to mitigate high rates have been provided to the PUB, which has final say, similar to how Manitoba Hydro scaled back a planned increase in the next year.

Quebec shatters record for electricity consumption once again

Hydro Quebec Power Consumption Record surges amid extreme cold, peak demand, and grid stress, as Hydro-Quebec urges energy conservation, load management, and reduced heating during morning and evening peaks across Montreal and southern Quebec.

 

Key Points

Quebec's grid hit 40,300 MW during an extreme cold snap, setting a new record and prompting conservation appeals.

✅ Lower thermostats 1-2 C in unused rooms during peak hours

✅ Delay dishwashers, dryers, and hot water use to off-peak

✅ Peak windows: 6-9 a.m. and 4-8 p.m.; import power if needed

 

Hydro Quebec says it has once again set a new record for power consumption, echoing record-breaking demand in B.C. in 2021 as extreme cold grips much of the province.

An extreme cold warning has been in effect across southern Quebec since Friday morning, straining the system, just as Calgary's electricity use soared during a frigid February, as Quebecers juggle staying warm and working from home.

Hydro Québec recorded consumption levels reaching 40,300 megawatts as of 8 a.m. Friday, breaking a previous record of 39,000 MW (with B.C. electricity demand hit an all-time high during a similar cold snap) that was broken during another cold snap on Jan 11. 

The publicly owned utility is now asking Quebecers to reduce their electricity consumption as much as possible today and tomorrow, a move consistent with clean electricity goals under federal climate pledges, predicting earlier in the morning the province would again reach an all-time high.

Reducing heating by just one or two degrees, especially in rooms that aren't being used, is one step that people can take to limit their consumption. They can also avoid using large appliances like the dishwasher and clothing dryer as often, and shortening the use of hot water. 

"They're small actions, but across millions of clients, it makes a difference," said Cendrix Bouchard, a spokesperson with Hydro Québec, while speaking with Tout un matin.

"We understand that asking this may pose challenges for some who are home throughout the day because they are working remotely, but if people are able to contribute, we appreciate it."

The best time to try and limit electricity usage is in the morning and evening, when electricity usage tends to peak, Bouchard said.

The province can import electricity from other regions if Quebec's system reaches its limits, even as the utility pursues selling to the United States as part of its long-term strategy, he added.

Temperatures dropped to –24 C in Montreal at 7 a.m., with a wind chill of –29 C. 

It will get colder across the south of the province through the evening and wind chills are expected to make it feel as cold as – 40 until Saturday morning, Environment Canada warned.

Those spending time outdoors are at a higher risk of frostbite and hypothermia.

"Frostbite can develop within minutes on exposed skin, especially with wind chill," Environment Canada said.

Conserving energy
Hydro-Québec has signed up 160,000 clients to a flexible billing plan similar to BC Hydro's winter payment plan that allows them to pay less for energy — as long as they use it during non-peak periods.

Quebec's energy regulator, the Régie de l'énergie, also forces crypto-currency mining operations to shut down for some hours  on peak-demand days, a topic where BC Hydro's approach to crypto mining has also drawn attention, Bouchard said.

Hydro-Québec says the highest consumption periods are usually between 6 a.m.-9 a.m. and 4 p.m.-8 p.m.

Rolls-Royce expecting UK approval for mini nuclear reactor by mid-2024

Rolls-Royce SMR UK Approval underscores nuclear innovation as regulators review a 470 MW factory-built modular reactor, aiming for grid power by 2029 to boost energy security, cut fossil fuels, and accelerate decarbonization.

 

Key Points

UK regulatory clearance for Rolls-Royce's 470 MW modular reactor, targeting grid power by 2029 to support clean energy.

✅ UK design approval expected by mid 2024

✅ First 470 MW unit aims for grid power by 2029

✅ Modular, factory-built; est. £1.8b per 10-acre site

 

A Rolls-Royce (RR.L) design for a small modular nuclear reactor (SMR) will likely receive UK regulatory approval by mid-2024, reflecting progress seen in the US NRC safety evaluation for NuScale as a regulatory benchmark, and be able to produce grid power by 2029, Paul Stein, chairman of Rolls-Royce Small Modular Reactors.

The British government asked its nuclear regulator to start the approval process in March, in line with the UK's green industrial revolution agenda, having backed Rolls-Royce’s $546 million funding round in November to develop the country’s first SMR reactor.

Policymakers hope SMRs will help cut dependence on fossil fuels and lower carbon emissions, as projects like Ontario's first SMR move ahead in Canada, showing momentum.

Speaking to Reuters in an interview conducted virtually, Stein said the regulatory “process has been kicked off, amid broader moves such as a Canadian SMR initiative to coordinate development, and will likely be complete in the middle of 2024.

“We are trying to work with the UK Government, and others to get going now placing orders, echoing expansions like Darlington SMR plans in Ontario, so we can get power on grid by 2029.”

In the meantime, Rolls-Royce will start manufacturing parts of the design that are most unlikely to change, while advancing partnerships like a MoU with Exelon to support deployment, Stein added.

Each 470 megawatt (MW) SMR unit costs 1.8 billion pounds ($2.34 billion) and would be built on a 10-acre site, the size of around 10 football fields, though projects in New Brunswick SMR debate have prompted questions about costs and timelines.

Unlike traditional reactors, SMRs are cheaper and quicker to build and can also be deployed on ships and aircraft. Their “modular” format means they can be shipped by container from the factory and installed relatively quickly on any proposed site.
