GE Hitachi Nuclear Energy said it has submitted the revised design documents for its Economic Simplified Boiling Water Reactor (ESBWR) to the U.S. Nuclear Regulatory Commission.

GE Hitachi said the submission marks a milestone in the company's effort to move forward with the 1,520-megawatt design which two U.S. utilities have selected to use for two new nuclear plants, some of the first reactors proposed after a three-decade lapse in U.S. nuclear expansion.

Two other U.S. utilities dropped the ESBWR design fearing that the time needed to obtain NRC certification would slow their efforts to pursue construction of new reactors.

GE Hitachi, a venture of General Electric Co and Hitachi Ltd, said that the ESBWR design's advanced safety features and cost-saving advantages "are key in delivering the next generation of nuclear reactors worldwide."

Nuclear reactors generate about 20 percent of U.S. electricity and proponents say nuclear power is attractive because it emits none of the heat-trapping carbon dioxide that comes from power plants that burn coal and natural gas.

"As the United States debates energy policy, nuclear power should play a pivotal role, as nuclear generates virtually carbon-free electricity," said Jack Fuller, chief executive of the GE Hitachi alliance.

Detroit Edison of Michigan and Dominion Energy of Virginia have submitted construction license applications using the ESBWR technology. NuStart Energy, a U.S. Energy Department-supported consortium, also supported the ESBWR design.

Exelon Corp, the largest U.S. nuclear operator, dropped the ESBWR technology last year for a proposed new reactor in Texas while Entergy Corp suspended its NRC license application after being unable to reach agreement with GE Hitachi Nuclear on commercial terms for a proposed new plant in the Southeast.

Exelon called the ESBWR design "promising," while Entergy said its decision was not a criticism of the design.

Wilmington, North Carolina-based GE Hitachi Nuclear has two nuclear designs, the ESBWR and the 1,350-MW Advanced Boiling Water Reactor (ABWR) design which was certified by the NRC in 1997 and is operating in Japan.

Compared with typical U.S. nuclear reactors operating now, GE Hitachi said the ABWR and ESBWR designs are expected to have 30 to 40 percent lower operating and maintenance costs per kilowatt-hour thanks to an increased capacity factor and simpler systems.

Tube Strikes Disrupt London Economy

London Tube Strikes Economic Impact highlights transport disruption reducing foot traffic, commuter flows, and tourism, squeezing small businesses, hospitality revenue, and citywide growth while business leaders urge negotiations, resolution, and policy responses to stabilize operations.

 

Key Points

Reduced transport options cut foot traffic and sales, straining small businesses and slowing London-wide growth.

✅ Hospitality venues report lower revenue and temporary closures

✅ Commuter and tourism declines reduce daily sales and bookings

✅ Business groups urge swift negotiations to restore services

 

London's economy is facing significant challenges due to ongoing tube strikes, challenges that are compounded by scrutiny of UK energy network profits and broader cost pressures across sectors, with businesses across the city experiencing disruptions that are impacting their operations and bottom lines.

Impact on Small Businesses

Small businesses, particularly those in the hospitality sector, are bearing the brunt of the disruptions caused by the strikes. Many establishments rely on the steady flow of commuters and tourists that the tube system facilitates, while also hoping for measures like temporary electricity bill relief that can ease operating costs during downturns. With reduced transportation options, foot traffic has dwindled, leading to decreased sales and, in some cases, temporary closures.

Economic Consequences

The strikes are not only affecting individual businesses but are also having a ripple effect on the broader economy, a dynamic seen when commercial electricity consumption plummeted in B.C. during the pandemic. The reduced activity in key sectors is contributing to a slowdown in economic growth, echoing periods when BC Hydro demand fell 10% and prompting policy responses such as Ontario electricity rate reductions for businesses, with potential long-term consequences if the disruptions continue.

Calls for Resolution

Business leaders and industry groups are urging for a swift resolution to the strikes. They emphasize the need for dialogue between the involved parties to reach an agreement that minimizes further economic damage and restores normalcy to the city's transportation system.

The ongoing tube strikes in London are causing significant disruptions to the city's economy, particularly affecting small businesses that depend on the efficient movement of people. Immediate action is needed to address the issues, drawing on tools like a subsidized hydro plan used elsewhere to spur recovery, to prevent further economic downturn.

Sierra Club: Governor Abbott's Demands Would Leave Texas More Polluted and Texans in the Dark

Texas Energy Policy Debate centers on ERCOT and PUC directives, fossil fuels vs renewables, grid reliability, energy efficiency, battery storage, and blackout risks, shaping Texas power market rules, conservation alerts, and capacity planning.

 

Key Points

Policy fight over ERCOT/PUC rules weighing fossil fuels vs renewables and storage to bolster Texas grid reliability.

✅ ERCOT and PUC directives under political scrutiny

✅ Fossil fuel subsidies vs renewable incentives and storage

✅ Focus on grid reliability, efficiency, and blackout prevention

 

Earlier this week, Governor Abbott released a letter to the Public Utility Commission of Texas (PUC) and the Electric Reliability Council of Texas (ERCOT), demanding electricity market reforms that Abbott falsely claims will "increase power generation capacity and to ensure the reliability of the Texas power grid."

Unfortunately, Abbott's letter promotes polluting, unreliable fossil fuels, attacks safer clean energy options, and ignores solutions that would actually benefit everyday Texans.

"Governor Abbott, in a blatant effort to politicize Texans' energy security, wants to double down on fossil fuels, even though they were the single largest point of failure during both February's blackouts and June's energy conservation alerts," said Cyrus Reed, Interim Director & Conservation Director of the Lone Star Chapter of the Sierra Club.

"Many of these so-called solutions were considered and rejected most recently by the Texas Legislature. Texas must focus on expanding clean and reliable renewable energy, energy efficiency, and storage capacity, as voters consider funding to modernize generation in the months ahead.

"We can little afford to repeat the same mistakes that have failed to provide enough electricity where it is needed most and cost Texans billions of dollars. Instead of advocating for evidence-based solutions, Abbott wants to be a culture warrior for coal and gas, even as he touts grid readiness amid election season, even when it results in blackouts across Texas."

Ukraine Leans on Imports to Keep the Lights On

Ukraine Electricity Imports surge to record levels as EU neighbors bolster grid stability amid Russian strikes, supporting energy security, preventing blackouts, and straining cross-border transmission capacity while Ukraine rebuilds damaged infrastructure and diversifies with renewables.

 

Key Points

Emergency EU power purchases stabilizing Ukraine’s grid after war damage.

✅ Record 19,000 MWh per day from EU interconnectors

✅ Supports grid stability and blackout prevention

✅ Cost and transmission upgrades challenge sustainability

 

Russia's ongoing war in Ukraine has extended far beyond the battlefield, with critical infrastructure becoming a target. Ukraine's once-robust energy system has sustained significant damage amid energy ceasefire violations and Russian missile and drone strikes. To cope with these disruptions and maintain power supplies for Ukrainian citizens, the country is turning to record-breaking electricity imports from neighboring European nations.

Prior to the war, Ukraine enjoyed a self-sufficient energy sector, even exporting electricity to neighboring countries. However, targeted attacks on power plants and transmission lines have crippled generation capacity. The situation is particularly dire in eastern and southern Ukraine, where ongoing fighting has caused extensive damage.

Faced with this energy crisis, Ukraine is looking to Europe for a lifeline. The country's energy ministry has announced plans to import a staggering amount of electricity – exceeding 19,000 megawatt-hours (MWh) per day – to prepare for winter and stabilize supplies. This surpasses the previous record set in March 2024 and represents a significant increase in Ukraine's reliance on external power sources.

Several European nations are stepping up to support Ukraine. Countries like Poland, Slovakia, Romania, Hungary, which maintains quiet energy ties with Russia today, and Moldova have agreed to provide emergency electricity supplies. These imports will help stabilize Ukraine's power grid and prevent widespread blackouts, especially during peak consumption hours.

The reliance on imports, however, presents its own set of challenges. Firstly, the sheer volume of electricity needed puts a strain on the capacity of neighboring grids. Upgrading and expanding transmission infrastructure will be crucial to ensure a smooth flow of electricity. Secondly, the cost of imported electricity can be higher than domestically generated power amid price hikes and instability globally, placing additional pressure on Ukraine's already strained finances.

Beyond these immediate concerns, the long-term implications of relying on external energy sources need to be considered. Ukraine's long-term goal is to rebuild its own energy infrastructure and regain energy independence. International assistance, including energy security support measures, will be crucial in this endeavor. Financial aid and technical expertise can help Ukraine repair damaged power plants, diversify its energy mix through further investment in renewables, and develop more resilient grid infrastructure.

The war in Ukraine has underscored the importance of energy security. A nation's dependence on a single source of energy, be it domestic or foreign, leaves it vulnerable to disruption, as others consider national security and fossil fuels in their own policies. For Ukraine, diversification and building a more resilient energy infrastructure are key takeaways from this crisis.

The international community also has a role to play. Supporting Ukraine's energy sector not only helps the nation weather the current crisis but also strengthens European energy security as a whole, where concerns over Europe's energy nightmare remain pronounced. A stable and independent Ukraine, less reliant on Russian energy, contributes to a more secure and prosperous Europe.

As the war in Ukraine continues, the battle for energy security rages on. While the immediate focus is on keeping the lights on through imports, the long-term goal for Ukraine is to rebuild a stronger, more resilient energy sector that can power the nation's future. The international community's support will be crucial in helping Ukraine achieve this goal.

Sustainable Marine now delivering electricity to Nova Scotia grid from tidal energy

Sustainable Marine tidal energy delivers in-stream power to Nova Scotia's grid from Grand Passage, proving low-impact, renewable generation and advancing a floating tidal array at FORCE and Minas Passage in the Bay of Fundy.

 

Key Points

The first in-stream tidal project supplying clean power to Nova Scotia's grid, proven at Grand Passage.

✅ First to deliver in-stream tidal power to Canada's grid

✅ Demonstration at Grand Passage informs FORCE deployments

✅ Low-impact design and environmental monitoring validated

 

Sustainable Marine has officially powered up its tidal energy operation in Canada and is delivering clean electricity to the power system in Nova Scotia, on the country’s Atlantic coast, as the province moves to increase wind and solar projects in the years ahead. The company’s system in Grand Passage is the first to deliver in-stream tidal power to the grid in Canada, following provincial approval to harness Bay of Fundy tides that is spurring further development.

The system start-up is the culmination of more than a decade of research, development and testing, including lessons from Scottish tidal projects in recent years and a powerful tidal turbine feeding onshore grids, managing the technical challenges associated with operating in highly energetic environments and proving the ultra-low environmental impact of the tidal technology.

Sustainable Marine is striving to deliver the world’s first floating tidal array at FORCE (Fundy Ocean Research Centre for Energy). This project will be delivered in phases, drawing upon the knowledge gained and lessons learned in Grand Passage, and insights from offshore wind pilots like France’s first offshore wind turbine in Europe. In the coming months the company will continue to operate the platform at its demonstration site at Grand Passage, gradually building up power production, while New York and New England clean energy demand continues to rise, to further prove the technology and environmental monitoring systems, before commencing deployments in the Minas Passage – renowned as the Everest of tidal energy.

The Bay of Fundy’s huge tidal energy resource contains more than four times the combined flow of every freshwater river in the world, with the potential to generate approximately 2,500 MW of green energy, underscoring why independent electricity planning will be important for integrating marine renewables.

BC Hydro activates "winter payment plan"

BC Hydro Winter Payment Plan lets customers spread electricity bills over six months during cold weather, easing costs amid colder-than-average temperatures in British Columbia, with low-income conservation support, energy-saving kits, and insulation upgrades.

 

Key Points

Allows BC Hydro customers to spread winter electricity bills over six months, with added low-income efficiency support.

✅ Spread Dec-Mar bills across six months

✅ Eases costs during colder-than-average temperatures

✅ Includes low-income conservation and energy-saving kits

 

As colder temperatures set in across the province again this weekend, BC Hydro says it is activating its winter payment plan to give customers the opportunity to spread out their electricity bills as demand can reach record levels during extreme cold periods.

"Our meteorologists are predicting colder-than-average temperatures will continue over the next of couple of months and we want to provide customers with help to manage their payments," said Chris O'Riley, BC Hydro's president.

All BC Hydro customers will be able to spread payments from the billing period spanning Dec. 1, 2017 to March 31, 2018 over a six-month period.

Cold weather in the second half of December 2017 led to surging electricity demand that was higher than the previous 10-year average and has at times hit all-time highs during peak usage periods, according to BC Hydro.

Hydro operations also respond to summer conditions, as drought and low rainfall can force adjustments in power generation strategies.

People who heat their homes with electricity — about 40 per cent of British Columbians —  have the highest overall bills in the province, $197 more in December than in July, when air conditioning use can affect energy costs.

This is the second year the Crown corporation has activated a cold-weather payment plan, part of broader customer assistance programs it offers.  

BC Hydro has also increased funding for its low-income conservation programs by $2.2 million for a total of $10 million over the next three years. 

The low-income program provides energy-saving kits that include things like free energy assessments, insulation upgrades and weather stripping.

Nord Stream: Norway and Denmark tighten energy infrastructure security after gas pipeline 'attack'

Nord Stream Pipeline Sabotage triggers Baltic Sea gas leaks as Norway and Denmark tighten energy infrastructure security, offshore surveillance, and exclusion zones, after drone sightings near platforms and explosions reported by experts.

 

Key Points

An alleged attack causing Baltic gas leaks and heightened energy security measures in Norway and Denmark.

✅ Norway boosts offshore and onshore site security

✅ Denmark enforces 5 nm exclusion zone near leaks

✅ Drones spotted; police probe sabotage and safety breaches

 

Norway and Denmark will increase security and surveillance around their energy infrastructure sites after the alleged sabotage of Russia's Nord Stream gas pipeline in the Baltic Sea, as the EU pursues a plan to dump Russian energy to safeguard supplies. 

Major leaks struck two underwater natural gas pipelines running from Russia to Germany, which has moved to a 200 billion-euro energy shield amid surging prices, with experts reporting that explosions rattled the Baltic Sea beforehand.

Norway -- an oil-rich nation and Europe's biggest supplier of gas -- will strengthen security at its land and offshore installations, even as it weighs curbing electricity exports to avoid shortages, the country's energy minister said.

The Scandinavian country's Petroleum Safety Authority also urged vigilance on Monday after unidentified drones were seen flying near Norway's offshore oil and gas platforms.

"The PSA has received a number of warnings/notifications from operator companies on the Norwegian Continental Shelf concerning the observation of unidentified drones/aircraft close to offshore facilities" the agency said in a statement.

"Cases where drones have infringed the safety zone around facilities are now being investigated by the Norwegian police."

Meanwhile Denmark will increase security across its energy sector after the Nord Stream incident, as wider market strains, including Germany's struggling local utilities, ripple across Europe, a spokesperson for gas transmission operator Energinet told Upstream.

The Danish Maritime Agency has also imposed an exclusion zone for five nautical miles around the leaks, warning ships of a danger they could lose buoyancy, and stating there is a risk of the escaping gas igniting "above the water and in the air," even as Europe weighs emergency electricity measures to limit prices.

Denmark's defence minister said there was no cause for security concerns in the Baltic Sea region.

"Russia has a significant military presence in the Baltic Sea region and we expect them to continue their sabre-rattling," Morten Bodskov said in a statement.

Video taken by a Danish military plane on Tuesday afternoon showed the extent of one of gas pipeline leaks, with the surface of the Baltic bubbling up as gas escapes, highlighting Europe's energy crisis for global audiences:

Meanwhile police in Sweden have opened a criminal investigation into "gross sabotage" of the Nord Stream 1 and Nord Stream 2 pipelines, and Sweden's crisis management unit was activated to monitor the situation. The unit brings together representatives from different government agencies. 

Swedish Foreign Minister Ann Linde had a call with her Danish counterpart Jeppe Kofod on Tuesday evening, and the pair also spoke with Norwegian Foreign Minister Anniken Huitfeldt on Wednesday, as the bloc debates gas price cap strategies to address the crisis, with Kofod saying there should be a "clear and unambiguous EU statement about the explosions in the Baltic Sea." 

"Focus now on uncovering exactly what has happened - and why. Any sabotage against European energy infrastructure will be met with a robust and coordinated response," said Kofod.
