Hitachi UK Nuclear Project Freeze reflects Horizon Nuclear Power's suspended Anglesey plant amid Brexit uncertainty, investor funding gaps, rising safety regulation costs, and a 300 billion yen write-down, impacting Britain's low-carbon electricity plans.

Key Points

Hitachi halted Horizon's Anglesey nuclear plant over funding and Brexit risks, recording a 300 billion yen write-down.

✅ 3 trillion yen UK nuclear project funding stalled

✅ 300 billion yen impairment wipes Horizon asset value

✅ Brexit, safety rules raised costs and investor risk

Japan’s Hitachi Ltd said on Thursday it has decided to freeze a 3 trillion yen ($28 billion) British nuclear power project and will consequently book a write down of 300 billion yen.

The suspension comes as Hitachi’s Horizon Nuclear Power failed to find private investors for its plans to build a plant in Anglesey, Wales, where local economic concerns have been raised, which promised to provide about 6 percent of Britain’s electricity.

“We’ve made the decision to freeze the project from the economic standpoint as a private company,” Hitachi said in a statement.

Hitachi had called on the British government to boost financial support for the project to appease investor anxiety, but turmoil over the country’s impending exit from the European Union limited the government’s capacity to compile plans, people close to the matter previously said.

Hitachi had called on the British government to boost financial support for the project to appease investor anxiety, but turmoil over the country’s impending exit from the European Union and setbacks at Hinkley Point C limited the government’s capacity to compile plans, people close to the matter previously said.

Hitachi had banked on a group of Japanese investors and the British government each taking a one-third stake in the equity portion of the project, the people said. The project would be financed one-third by equity and rest by debt.

The nuclear writedown wipes off the Horizon unit’s asset value, which stood at 296 billion yen as of September-end.

Hitachi stopped short of scrapping the northern Wales project. The company will continue to discuss with the British government on nuclear power, it said.

However, industry sources said hurdles to proceed with the project are high considering tighter safety regulations since a meltdown at Japan’s Fukushima nuclear power plant in 2011 drove up costs, even as Europe’s nuclear decline strains energy planning.

Analysts and investors viewed the suspension as an effective withdrawal and saw the decision as a positive step that has removed uncertainties for the Japanese conglomerate.

Hitachi bought Horizon in 2012 for 696 million pounds ($1.12 billion), fromE.ON and RWE as the German utilities decided to sell their joint venture following Germany’s nuclear exit after the Fukushima accident.

Hitachi’s latest decision further dims Japan’s export prospects, even as some peers pursue UK offshore wind investments to diversify.

Toshiba Corp last year scrapped its British NuGen project after its US reactor unit Westinghouse went bankrupt, while Westinghouse in China reported no major impact, and it failed to sell NuGen to South Korea’s KEPCO.

Mitsubishi Heavy Industries Ltd has effectively abandoned its Sinop nuclear project in Turkey, a person involved in the project previously told Reuters, as cost estimates had nearly doubled to around 5 trillion yen.

Great Britain electricity generation spans renewables and baseload: wind, solar, nuclear, gas, and biomass, supported by National Grid interconnectors, embedded energy estimates, and BMRS data for dynamic imports and exports across Europe.

Key Points

A diverse, weather-driven mix of renewables, gas, nuclear, and imports coordinated by National Grid.

✅ Baseload from nuclear and biomass; intermittent wind and solar

✅ Interconnectors trade zero carbon imports via subsea cables

✅ Data from BMRS and ESO covers embedded energy estimates

Great Britain has one of the most diverse ranges of electricity generation in Europe, with everything from windfarms off the coast of Scotland to a nuclear power station in Suffolk tasked with keeping the lights on. The increasing reliance on renewable energy sources, as part of the country’s green ambitions, also means there can be rapid shifts in the main source of electricity generation. On windy days, most electricity generation comes from record wind generation across onshore and offshore windfarms. When conditions are cold and still, gas-fired power stations known as peaking plants are called into action.

The electricity system in Great Britain relies on a combination of “baseload” power – from stable generators such as nuclear and biomass plants – and “intermittent” sources, such as wind and solar farms that need the right weather conditions to feed energy into the grid. National Grid also imports energy from overseas, through subsea cables known as interconnectors that link to France, Belgium, Norway and the Netherlands. They allow companies to trade excess power, such as renewable energy created by the sun, wind and water, between different countries. By 2030 it is hoped that 90% of the energy imported by interconnectors will be from zero carbon energy sources, though low-carbon electricity generation stalled in 2019 for the UK.

The technology behind Great Britain’s power generation has evolved significantly over the last century, and at times wind has been the main source of electricity. The first integrated national grid in the world was formed in 1935 linking seven regions of the UK. In the aftermath of industrialisation, coal provided the vast majority of power, before oil began to play an increasingly important part in the 1950s. In 1956, the world’s first commercial nuclear reactor, Calder Hall 1 at Windscale (later Sellafield), was opened by Queen Elizabeth II. Coal use fell significantly in the 1990s while the use of combined cycle gas turbines grew, and in 2016 wind generated more electricity than coal for the first time. Now a combination of gas, wind, nuclear and biomass provide the bulk of Great Britain’s energy, with smaller sources such as solar and hydroelectric power also used. From October 2024, coal will no longer be used to generate electricity, following coal-free power records set in recent years.

Energy generation data is fetched from the Balancing Mechanism Reporting Service public feed, provided by Elexon – which runs the wholesale energy market – and is updated every five minutes, covering periods when wind led the power mix as well.

Elexon’s data does not include embedded energy, which is unmetered and therefore invisible to Great Britain’s National Grid. Embedded energy comprises all solar energy and wind energy generated from non-metered turbines. To account for these figures we use embedded energy estimates from the National Grid electricity system operator, which are published every 30 minutes.

Import figures refer to the net flow of electricity from the interconnectors with Europe and with Northern Ireland. A positive value represents import into the GB transmission system, while a negative value represents an export.

Hydro figures combine renewable run-of-the-river hydropower and pumped storage.

Biomass figures include Elexon’s “other” category, which comprises coal-to-biomass conversions and biomass combined heat and power plants.

AI-Powered Utility Customer Experience enables transparency, real-time pricing, smart thermostats, demand response, and billing optimization, helping utilities integrate distributed energy resources, battery storage, and microgrids while boosting customer satisfaction and reducing costs.

Key Points

An approach where utilities use AI and real-time data to personalize service, optimize billing, and cut energy costs.

✅ Real-time pricing aligns retail and wholesale market signals

✅ Device control via smart thermostats and home energy management

✅ Analytics reveal appliance-level usage and personalized savings

The latest electric utility customer satisfaction survey results from the American Customer Satisfaction Index (ACSI) Energy Utilities report reveal that nearly every investor-owned utility saw customer satisfaction go down from 2018 to 2019. Residential customers are sending a clear message in the report: They want more transparency and control over energy usage, billing and ways to reduce costs.

With both customer satisfaction and utility revenues on the decline, utilities are facing daunting challenges to their traditional business models amid flat electricity demand across many markets today. That said, it is the utilities that see these changing times as an opportunity to evolve that will become the energy leaders of tomorrow, where the customer relationship is no longer defined by sales volume but instead by a utility company's ability to optimize service and deliver meaningful customer solutions.

We have seen how the proliferation of centralized and distributed renewables on the grid has already dramatically changed the cost profile of traditional generation and variability of wholesale energy prices. This signals the real cost drivers in the future will come from optimizing energy service with things like batteries, microgrids and peer-to-peer trading networks. In the foreseeable future, flat electricity rates may be the norm, or electricity might even become entirely free as services become the primary source of utility revenue.

The key to this future is technological innovation that allows utilities to better understand a customer’s unique needs and priorities and then deliver personalized, well-timed solutions that make customers feel valued and appreciated as their utility helps them save and alleviates their greatest pain points.

I predict utilities that adopt new technologies focused on customer experience, aligned with key utility trends shaping the sector, and deliver continual service improvements and optimization will earn the most satisfied, most loyal customers.

To illustrate this, look at how fixed pricing today is applied for most residential customers. Unless you live in one of the states with deregulated utilities where most customers are free to choose a service provider in a competitive marketplace, as consumers in power markets increasingly reshape offerings, fixed-rate tariffs or time-of-use tariffs might be the only rate structures you have ever known, though new utility rate designs are being tested nationwide today. These tariffs are often market distortions, bearing little relation to the real-time price that the utility pays on the wholesale market.

It can be easy enough to compare the rate you pay as a consumer and the market rate that utilities pay. The California ISO has a public dashboard -- as do other grid operators -- that shows the real-time marginal cost of energy. On a recent Friday, for example, a buyer in San Francisco could go to the real-time market and procure electricity at a rate of around 9.5 cents per kilowatt-hour (kWh), yet a residential customer can pay the utility PG&E between 22 cents and 49 cents per kWh amid major changes to electric bills being debated, depending on usage.

The problem is that utility customers do not usually see this data or know how to interpret it in a way that helps add value to their service or drive down the cost.

This is a scenario ripe for innovation. Artificial intelligence (AI) technologies are beginning to be applied to give customers the transparency and control over the energy they desire, and a new type of utility is emerging using real-time pricing signals from wholesale markets to give households hassle-free energy savings. Evolve Energy in Texas is developing a utility service model, even as Texas utilities revisit smart home network strategies, that delivers electricity to consumers at real-time market prices and connects to smart thermostats and other connected devices in the home for simple monitoring and control -- all managed via an intuitive consumer app.

My company, Bidgely, partners with utilities and energy retailers all over the world to apply artificial intelligence and machine learning algorithms to customer data in order to bring transparency to their electricity bills, showing exactly where the customers’ money is going down to the appliance and offering personalized, actionable advice on how to save.

Another example is from energy management company Keewi. Its wireless outlet adaptors are revealing real-time energy usage information to Texas A&M dorm residents as well as providing students the ability to conserve energy through controlling items in their rooms from their smartphones.

These are but a few examples of innovations among many in play that answer the consumer demand for increased transparency and control over energy usage.

Electric service providers will be closely watching how consumers respond to AI-driven innovation, including providers in traditionally regulated markets that are exploring equitable regulation approaches now, to stay aligned with policy and customer expectations. While regulated utilities have no reason to fear that their customers might sign up with a competitor, they understand that the revenues from electricity sales are going down and the deployment of distributed energy resources is going up. Both trends were reflected in a March report from Bloomberg New Energy Finance (via ThinkProgress) that claimed unsubsidized storage projects co-located with solar or wind are starting to compete with coal and gas for dispatchable power. Change is coming to regulated markets, and some of that change can be attributed to customer dissatisfaction with utility service.

Like so many industries before, the utility-customer relationship is on track to become less about measuring unit sales and more about driving revenue through services and delivering the best customer value. Loyal customers are most likely to listen and follow through on the utility’s advice and to trust the utility for a wide range of energy-related products and services. Utilities that make customer experience the highest priority today will emerge tomorrow as the leaders of a new energy service era.

India Nuclear Generation Shortfall highlights missed five-year plan targets due to uranium fuel scarcity, commissioning delays at Kudankulam, PFBR slippage, and PHWR equipment bottlenecks under IAEA safeguards and domestic supply constraints.

Key Points

A gap between planned and actual nuclear output due to fuel shortages, reactor delays, and first-of-a-kind hurdles.

✅ Fuel scarcity pre-2009-10 constrained unsafeguarded reactors.

✅ Kudankulam delays from protests, litigation, and remobilisation.

✅ FOAK PHWR equipment bottlenecks and PFBR slippage.

A lack of available domestically produced nuclear fuel and delays in constructing and commissioning nuclear power plants, including first-of-a-kind plants and the Prototype Fast Breeder Reactor (PFBR), meant that India failed to meet its nuclear generation targets under the governmental plans over the decade to 2017, even as global project milestones were being recorded elsewhere.

India's nuclear generation target under its 11th five-year plan, covering the period 2007-2012, was 163,395 million units (MUs) and the 12th five-year Plan (2012-17) was 241,748 MUs, Minister of state for the Department of Atomic Energy and the Prime Minister's Office Jitendra Singh told parliament on 6 February. Actual nuclear generation in those periods was 109,642 MUs and 183,488 MUs respectively, Singh said in a written answer to questions in the Lok Sabah.

Singh attributed the shortfall in generation to a lack of availability of the necessary quantities of domestically produced fuel during the three years before 2009-2010; delays to the commissioning of two 1000 MWe nuclear power plants at Kudankulam due to local protests and legal challenges; and delays in the completion of two indigenously designed pressurised heavy water reactors and the PFBR.

Kudankulam 1 and 2 are VVER-1000 pressurised water reactors (PWRs) supplied by Russia's Atomstroyexport under a Russian-financed contract. The units were built by Nuclear Power Corporation of India Ltd (NPCIL) and were commissioned and are operated by NPCIL under International Atomic Energy Agency (IAEA) safeguards, with supervision from Russian specialists, while China's nuclear program advanced on a steady development track in the same period. Construction of the units - the first PWRs to enter operation in India - began in 2002.

Singh said local protests resulted in the halt of commissioning work at Kudankulam for nine months from September 2011 to March 2012, when he said project commissioning had been at its peak. As a consequence, additional time was needed to remobilise the workforce and contractors, he said. Litigation by anti-nuclear groups, and compliance with supreme court directives, impacted commissioning in 2013, he said. Unit 1 entered commercial operation in December 2014 and unit 2 in April 2017.

Delays in the manufacture and supply by domestic industry of critical equipment for first-of-a-kind 700 MWe pressurised heavy water reactors -  Kakrapar units 3 and 4, and Rajasthan units 7 and 8 - has led to delays in the completion of those units, the minister said, as well as noting the delay in completion of the PFBR, which is being built at Kalpakkam by Bhavini. In answer to a separate question, Singh said the PFBR is in an "advance stage of integrated commissioning" and is "expected to approach first criticality by the year 2020."

Eight of India's operating nuclear power plants are not under IAEA safeguards and can therefore only use indigenously-sourced uranium. The other 14 units operate under IAEA safeguards and can use imported uranium. The Indian government has taken several measures to secure fuel supplies for reactors in operation and under construction, amid coal supply rationing pressures elsewhere in the power sector, concluding fuel supply contracts with several countries for existing and future reactors under IAEA Safeguards and by "augmentation" of fuel supplies from domestic sources, Singh said.

Kakrapar 3 and 4, with Kakrapar 3 criticality already reported, and Rajasthan 7 and 8 are all currently expected to enter service in 2022, according to World Nuclear Association information.

Joint venture discussions

In February 2016 the government amended the Atomic Energy Act to allow NPCIL to form joint venture companies with other public sector undertakings (PSUs) for involvement in nuclear power generation and possibly other aspects of the fuel cycle, reflecting green industrial strategies shaping future reactor waves globally. In answer to another question, Singh confirmed that NPCIL has entered into joint ventures with NTPC Limited (National Thermal Power Corporation, India's largest power company) and Indian Oil Corporation Limited. Two joint venture companies - Anushakti Vidhyut Nigam Limited and NPCIL-Indian Oil Nuclear Energy Corporation Limited - have been incorporated, and discussions on possible projects to be set up by the joint venture companies are in progress.

An exploratory discussion had also been held with Oil & Natural Gas Corporation, Singh said. Indian Railways - which has in the past been identified as a potential joint venture partner for NPCIL - had "conveyed that they were not contemplating entering into an MoU for setting up of nuclear power plants," Singh said.

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.

Bruce Power Capacity Uprate boosts nuclear output through generator stator upgrades, turbine and transformer enhancements, and cooling pump improvements at Bruce A and B, unlocking megawatts and efficiency gains from legacy heavy water design capacity.

Key Points

Upgrades that raise Bruce Power capacity via stator, turbine, transformer, and cooling enhancements.

✅ Generator stator replacement increases electrical conversion efficiency

✅ Turbine and transformer upgrades enable higher MW output

✅ Cooling pump enhancements optimize plant thermal performance

Bruce Power’s Unit 3 nuclear reactor will squeeze out an extra 22 megawatts of electricity, thanks to upgrades during its recent planned outage for refurbishment.

Similar gains are anticipated at its three sister reactors at Bruce A generating station, which presents the opportunity for the biggest efficiency gains and broader economic benefits for Ontario, due to a design difference over Bruce B’s four reactors, Bruce Power spokesman John Peevers said.

Bruce A reactor efficiency gains stem mainly from the fact Bruce A’s non-nuclear side, including turbines and the generator, was sized at 88 per cent of the nuclear capacity, Peevers said, while early Bruce C exploration work advances.

This allowed 12 per cent of the energy, in the form of steam, to be used for heavy water production, which was discontinued at the plant years ago. Heavy water, or deuterium, is used to moderate the reactors.

That design difference left a potential excess capacity that Bruce Power is making use of through various non-nuclear enhancements. But the nuclear operator, which also made major PPE donations during the pandemic, will be looking at enhancements at Bruce B as well, Peevers said.

Bruce Power’s efficiency gain came from “technology advancements,” including a “generator-stator improvement project that was integral to the uprate,” and contributed to an operating record at the site, a Bruce Power news release said July 11.

Peevers said the stationary coils and the associated iron cores inside the generator are referred to as the stator. The stator acts as a conductor for the main generator current, while the turbine provides the mechanical torque on the shaft of the generator.

“Some of the other things we’re working on are transformer replacement and cooling pump enhancements, backed by recent manufacturing contracts, which also help efficiency and contribute to greater megawatt output,” Peevers said.

The added efficiency improvements raised the nuclear operator’s peak generating capacity to 6,430 MW, as projects like Pickering life extensions continue across Ontario.
