When the sun has just set and the day's winds have died down, most people welcome the start of a peaceful evening.

But for people living in sustainable energy homes and relying on solar energy or wind power, it could be the beginning of a tense night. For them, falling back on the power grid to heat and light their homes could cost them money they didn't plan to spend.

Energy storage in most people's lives is simple. We hardly give a second thought to the batteries in flashlights, smartphones, laptops and hybrid cars.

The goal of total home energy sustainability, however — running your entire home on a battery for hours or days at a time — remains a dream. It's neither cheap nor subsidized, as solar energy-equipped homes often are. The eco-home industry has won a niche in the marketplace using smart design, sophisticated power use and backup fuel cells, but it still relies on the traditional power grid for some of its power.

But countless dreamers are working to transform the dream of total sustainability into reality. In Japan, for instance, at Sanyo's Kasai Green Energy Park, the company has showcased cutting-edge technology storing and managing solar energy on a grand scale.

Sanyo, now a member of the Panasonic Group, has connected 310,000 cylindrical lithium-ion batteries, each twice the size of an AA battery, to run as one huge battery. It has a 1.5 megawatt storage capacity, equivalent to the energy consumption of 150 homes for a day.

Sanyo's energy management system controls how much live solar panel or stored power the plant's administration office uses. This includes combining these power sources against the available outside power grid, offsetting the costs of using paid-for electricity during peak hours. “It's like getting the best out of your rechargeable batteries on a laptop, only on a much larger scale,” says Hiroshi Hanafusa, deputy general manager for Sanyo's smart energy systems division.

The storage system is charged by one megawatt one thousand watts of Sanyo HIT photovoltaic solar panels, which cover the sides and roofs of the entire plant. There are also 24/7 charging stations for Sanyo electric bikes and cellphones as well as a hybrid car charge station. The plant's Panasonic-developed LED lights also draw from the park. Sanyo says the park will reduce CO2 emissions by 2,480 tonnes per year and plans to incorporate the storage system as backup for the entire plant.

But what does a setup like this cost and who can afford it? Sanyo won't say what its Kasai battery storage component cost but hinted that a typical house energy storage installation would be double the cost of a solar panel home installation.

Even large Canadian solar panel installations such as those on the three IKEA Ontario stores in North York, Etobicoke and Vaughan would find it cost-prohibitive to install large-scale energy storage. Totaling 960,000 kilowatt hours generated per year, the three IKEA installations can actually profit by selling back their generated energy to the Ontario feed-in tariff rate of 71.3 cents per kilowatt. IKEA's $4.6-million solar power investment could be paid back in less than seven years.

“The benefit for a retail location like IKEA to invest in a system similar to the Kasai production plant could work if Ontario adapted ‘peak-tie’ options like Japan,” said David Thurgood, general manager of Sanyo Canada's Smart Energy Solutions Group. Sanyo officials added that IKEA could also benefit from selling its stored power anytime to future customers, such as hybrid car charging stations.

Sanyo envisions its current energy storage technology used commercially home use could be a decade away. But the technology is not without its own environmental concerns — the safe disposal of millions of end-of-life batteries would not be a simple task. It's estimated it would take more than 600 million of Sanyo's Kasai “big battery” to store the collected energy of the sun's rays that reach the earth's atmosphere.

A resilient Germany is weathering the energy crunch

German Energy Price Brakes harness price signals in a market-based policy, cutting gas consumption, preserving industrial output, and supporting CO2 reduction, showcasing Germany's resilience and adaptation while protecting households and businesses across Europe.

 

Key Points

Fixed-amount subsidies preserving price signals to curb gas use, shield consumers, and sustain industrial output.

✅ Maintains incentives via market-based price signals

✅ Cuts gas consumption without distorting EU markets

✅ Protects households and industry while curbing CO2

 

German industry and society are once again proving much more resilient and adaptable than certain people feared. Horror scenarios of a dangerous energy rationing or a massive slump in our economy have often been bandied about. But we are nowhere near that. With a challenging year just behind us, this is good news — not only for Germany, but also for Europe, where France-Germany energy cooperation has strengthened solidarity.

Companies and households reacted swiftly to the sharp increases in energy prices, in line with momentum in the global energy transition seen across markets. They installed more efficient heating or production facilities, switched to alternatives and imported intermediate products. The results are encouraging: German households and businesses have reduced gas consumption significantly, despite recent cold weather. From the start of the war in Ukraine to mid-December industrial gas consumption in Germany was (temperature-adjusted) around 20 per cent lower than the average level for the preceding three years. Even if some firms have cut back production, especially in energy-intensive sectors, industrial output as a whole has only fallen by about 1 per cent since the start of 2022. Added to this, in a survey released by the Ifo institute in November, over a third of German companies saw the potential to reduce gas consumption further without endangering output.

Instead of imposing excessive laws and regulations, we have relied on price signals and the prudence of market participants to create the right incentives and reduce gas consumption, as falling costs like record-low solar power prices continue to reinforce those signals across sectors.

We will follow this approach in coming months, when energy savings will remain important, even as the EU electricity outlook anticipates sharply higher demand by 2050. Our latest relief measures will not distort price signals. To this end, the Bundestag approved gas and electricity price brakes in its final session in 2022. They are designed to function without any intervention in markets or prices. This system will pay out a fixed amount relative to previous years’ consumption and the current difference to a reference price — regardless of current consumption.

Energy price brakes are the main component of Germany’s “protective shield”, which makes up to €200bn available for measures in 2022 to 2024. Seen in relation to the German economy’s size, its past heavy reliance on Russian energy imports and the fact that the measures will expire in 2024, these are balanced and expedient mechanisms. In contrast to instruments used in other countries, our new arrangements will not affect the price formation process driven by supply and demand, or on incentives to save gas. Companies and households will continue to save the full market price when they reduce consumption by a unit of gas or electricity. In this way, the price brakes also avoid the creation of additional demand for gas at the expense of consumers in other European countries, even as Europe’s Big Oil turning electric signals broader structural shifts in energy markets. No one need fear that competition will be distorted or that gas will be bought up. Indeed, a recent IMF working paper on cushioning the impact of high energy prices on households explicitly praises the German energy price brakes.

Current developments confirm the effectiveness of a market-based approach — and show that we should also rely on price signals when it comes to reducing CO₂ emissions, as suggested by IEA CO2 trends in recent years. Last year, households and companies had only a few weeks to adapt, yet we have already seen a strong response. The effect of CO₂ prices can be even stronger, as adaptation is possible over a much longer time and they additionally affect expectations and long-term decisions. Regulatory interventions and subsidy schemes, even if well targeted, cannot compete with market co-ordination and incentives that support individual decision-making and promote innovation.

Europe and Germany can weather this crisis without a collapse in industrial production. We also have an opportunity to deal efficiently with the move to climate neutrality, aligned with Germany’s hydrogen strategy for imported low-carbon fuels. In both cases, we should have confidence in price signals as well as in the power of people and business to innovate and adapt.

The Phillipines wants nuclear power to be included in the country's energy mix as the demand for electricity is expected to rise.

Philippines Nuclear Energy Policy aims to add nuclear power to the energy mix via executive order, meeting rising electricity demand with 24/7 baseload while balancing safety, renewables, and imported fuel dependence in the Philippines.

 

Key Points

A government plan to include nuclear power in the energy mix to meet demand, ensure baseload, and uphold safety.

✅ Executive order proposed by Energy Secretary Alfonso Cusi

✅ Targets 24/7 baseload, rising electricity demand

✅ Balances safety, renewables, and energy security

 

Phillipines Presidential spokesman Salvador Panelo said Energy Secretary Alfonso Cusi made the proposal during last Monday's Cabinet meeting in Malacaaang. "Secretary Cusi likewise sought the approval of the issuance of a proposed executive order for the inclusion of nuclear power, including next-gen nuclear options in the country's energy mix as the Philippines is expected to the rapid growth in electricity and electricity demand, in which, 24/7 power is essential and necessary," Panelo said in a statement.

Panelo said Duterte would study the energy chief's proposal, as China's nuclear development underscores regional momentum. In the 1960s until the mid 80s, the late president Ferdinand Marcos adopted a nuclear energy program and built the Bataan Nuclear Plant.

The nuclear plant was mothballed after Corazon Aquino became president in 1986. There have been calls to revive the nuclear plant, saying it would help address the Philippines' energy supply issues. Some groups, however, said such move would be expensive and would endanger the lives of people living near the facility, citing Three Mile Island as a cautionary example.

Panelo said proposals to revive the Bataan Nuclear Plant were not discussed during the Cabinet meeting, even as debates like California's renewable classification continue to shape perceptions. Indigenous energy sources natural gas, hydro, coal, oil, geothermal, wind, solar, biomassand ethanol constitute more than half or 59.6%of the Philippines' energy mix.

Imported oil make up 31.7% while imported coal, reflecting the country's coal dependency, contribute about 8.7%.

Imported ethanol make up 0.1% of the energy mix, even as interest in atomic energy rises globally.

In 2018, Duterte said safety should be the priority when deciding whether to tap nuclear energy for the country's power needs, as countries like India's nuclear restart proceed with their own safeguards.

BC announces grid development, job creation

BC Hydro Power Pathway accelerates electrification with clean energy investments, new transmission lines, upgraded substations, and renewable projects like wind and solar, strengthening the grid, supporting decarbonization, and creating jobs across British Columbia's growing economy.

 

Key Points

A $36B, 10-year BC Hydro plan to expand clean power infrastructure, accelerate electrification, and support jobs.

✅ $36B for new lines, substations, dam upgrades, and distribution

✅ Supports 10,500-12,500 jobs per year across B.C.

✅ Adds wind and solar, leveraging hydro to balance renewables

 

BC Hydro is gearing up for a decade of extensive construction to enhance British Columbia's electrical system, supporting a burgeoning clean economy and community growth while generating new employment opportunities.

Premier David Eby emphasized the necessity of expanding the electrical system for industrial growth, residential needs, and future advancements. He highlighted the role of clean, affordable energy in reducing pollution, securing well-paying jobs, and fostering economic growth.

At the B.C. Natural Resources Forum in Prince George, Premier Eby unveiled a $36-billion investment plan for infrastructure projects in communities and regions and green energy solutions to provide clean, affordable electricity for future generations.

The Power Pathway: Building BC’s Energy Future, BC Hydro’s revised 10-year capital plan, involves nearly $36 billion in investments across the province from 2024-25 to 2033-34. This marks a 50% increase from the previous plan of $24 billion and includes a substantial rise in electrification and emissions-reduction projects (nearly $10 billion, up from $1 billion).

These upcoming construction projects are expected to support approximately 10,500 to 12,500 jobs annually. The plan is set to bolster and sustain BC Hydro’s capital investments as significant projects like Site C are near completion.

The plan addresses the increasing demand for electricity due to population and housing growth, industrial development, such as a major hydrogen project, and the transition from fossil fuels to clean electricity. Key projects include constructing new high-voltage transmission lines from Prince George to Terrace, building or expanding substations in high-growth areas, and upgrading dams and generating facilities for enhanced safety and efficiency.

Minister of Energy, Mines, and Low Carbon Innovation Josie Osborne stated that this plan aims to build a clean energy future and support EV charging expansion while creating construction jobs. With BC Hydro’s capital plan allocating almost $4 billion annually for the next decade, it will drive economic growth and ensure access to clean, affordable electricity.

BC Hydro aims to add new clean, renewable energy sources like wind and solar, while acknowledging power supply challenges that must be managed as capacity grows. B.C.’s hydroelectric dams, functioning as batteries, enable the integration of intermittent renewables into the grid, providing reliable backup.

Chris O’Riley, president and CEO of BC Hydro, said the grid is one of the world’s cleanest. The new $36 billion capital plan encompasses investments in generation assets, large transmission infrastructure, and local distribution networks.

In partnership with BC Hydro, Premier Eby also announced a new streamlined approval process to expedite electrification for high-demand industries and support job creation, complementing measures like the BC Hydro rebate and B.C. Affordability Credit that help households.

Minister of Environment and Climate Change Strategy George Heyman highlighted the importance of rapid electrification in collaboration with the private sector to achieve CleanBC climate goals by 2030, including corridor charging via the BC's Electric Highway, and maintain the competitiveness of B.C. industries. The new process will streamline approvals for industrial electrification projects, enhancing efficiency and funding certainty.

Millions at Risk of Electricity Shut-Offs Amid Summer Heat

Summer Heatwave Electricity Shut-offs strain power grids as peak demand surges, prompting load shedding, customer alerts, and energy conservation. Vulnerable populations face higher risks, while cooling centers, efficiency upgrades, and renewables bolster resilience.

 

Key Points

Episodic power cuts during extreme heat to balance grid load, protect infrastructure, and manage peak demand.

✅ Causes: peak demand, heatwaves, aging grid, AC load spikes.

✅ Impacts: vulnerable households, health risks, economic losses.

✅ Solutions: load shedding, cooling centers, efficiency, renewables.

 

As temperatures soar across various regions, millions of households are facing the threat of U.S. blackouts due to strain on power grids and heightened demand for cooling during summer heatwaves. This article delves into the causes behind these potential shut-offs, the impact on affected communities, and strategies to mitigate such risks in the future.

Summer Heatwave Challenges

Summer heatwaves bring not only discomfort but also significant challenges to electrical grids, particularly in densely populated urban areas where air conditioning units and cooling systems, along with the data center demand boom, strain the capacity of infrastructure designed to meet peak demand. As temperatures rise, the demand for electricity peaks, pushing power grids to their limits and increasing the likelihood of disruptions.

Vulnerable Populations

The risk of electricity shut-offs disproportionately affects vulnerable populations, including low-income households, seniors, and individuals with medical conditions that require continuous access to electricity for cooling or medical devices. These groups are particularly susceptible to heat-related illnesses and discomfort when faced with more frequent outages during extreme heat events.

Utility Response and Management

Utility companies play a critical role in managing electricity demand and mitigating the risk of shut-offs during summer heatwaves. Strategies such as load shedding, where electricity is temporarily reduced in specific areas to balance supply and demand, and deploying AI for demand forecasting are often employed to prevent widespread outages. Additionally, utilities communicate with customers to provide updates on potential shut-offs and offer advice on energy conservation measures.

Community Resilience

Community resilience efforts are crucial in addressing the challenges posed by summer heatwaves and electricity shut-offs, especially as Canadian grids face harsher weather that heightens outage risks. Local governments, non-profit organizations, and community groups collaborate to establish cooling centers, distribute fans, and provide support services for vulnerable populations during heat emergencies. These initiatives help mitigate the health impacts of extreme heat and ensure that all residents have access to relief from oppressive temperatures.

Long-term Solutions

Investing in resilient infrastructure, enhancing energy efficiency, and promoting renewable energy sources are long-term solutions to reduce the risk of electricity shut-offs during summer heatwaves by addressing grid vulnerabilities that persist. By modernizing electrical grids, integrating smart technologies, and diversifying energy sources, communities can enhance their capacity to withstand extreme weather events and ensure reliable electricity supply year-round.

Public Awareness and Preparedness

Public awareness and preparedness are essential components of mitigating the impact of electricity shut-offs during summer heatwaves. Educating residents about energy conservation practices, encouraging the use of programmable thermostats, and promoting the importance of emergency preparedness plans empower individuals and families to navigate heat emergencies safely and effectively.

Conclusion

As summer heatwaves become more frequent and intense due to climate change impacts on the grid, the risk of electricity shut-offs poses significant challenges to communities across the globe. By implementing proactive measures, enhancing infrastructure resilience, and fostering community collaboration, stakeholders can mitigate the impact of extreme heat events and ensure that all residents have access to safe and reliable electricity during the hottest months of the year.

Oil crash only a foretaste of what awaits energy industry

Oil and Gas Profitability Decline reflects shale-driven oversupply, OPEC-Russia dynamics, LNG exports, renewables growth, and weak demand, signaling compressed margins for producers, stressed petrodollar budgets, and shifting energy markets post-Covid.

 

Key Points

A sustained squeeze on hydrocarbon margins from agile shale supply, weaker OPEC leverage, and expanding renewables.

✅ Shale responsiveness caps prices and erodes industry rents

✅ OPEC-Russia cuts face limited impact versus US supply

✅ Renewables and EVs slow long-term oil and gas demand

 

The oil-price crash of March 2020 will probably not last long. As in 2014, when the oil price dropped below $50 from $110 in a few weeks, this one will trigger a temporary collapse of the US shale industry. Unless the coronavirus outbreak causes Armageddon, cheap oil will also support policymakers’ efforts to help the global economy.

But there will be at least one important and lasting difference this time round — and it has major market and geopolitical implications.

The oil price crash is a foretaste of where the whole energy sector was going anyway — and that is down.

It may not look that way at first. Saudi Arabia will soon realise, as it did in 2015, that its lethal decision to pump more oil is not only killing US shale but its public finances as well. Riyadh will soon knock on Moscow’s door again. Once American shale supplies collapse, Russia will resume co-operation with Saudi Arabia.

With the world economy recovering from the Covid-19 crisis by then, and with electricity demand during COVID-19 shifting, moderate supply cuts by both countries will accelerate oil market recovery. In time, US shale producers will return too.

Yet this inevitable bounceback should not distract from two fundamental factors that were already remaking oil and gas markets. First, the shale revolution has fundamentally eroded industry profitability. Second, the renewables’ revolution will continue to depress growth in demand.

The combined result has put the profitability of the entire global hydrocarbon industry under pressure. That means fewer petrodollars to support oil-producing countries’ national budgets, including Canada's oil sector exposures. It also means less profitable oil companies, which traditionally make up a large segment of stock markets, an important component of so many western pension funds.

Start with the first factor to see why this is so. Historically, the geological advantages that made oil from countries such as Saudi Arabia so cheap to produce were unique. Because oil and gas were produced at costs far below the market price, the excess profits, or “rent”, enjoyed by the industry were very large.

Furthermore, collusion among low-cost producers has been a winning strategy. The loss of market share through output cuts was more than compensated by immediately higher prices. It was the raison d’être of Opec.

The US shale revolution changed all this, exposing the limits of U.S. energy dominance narratives. A large oil-producing region emerged with a remarkable ability to respond quickly to price changes and shrink its costs over time. Cutting back cheap Opec oil now only increases US supplies, with little effect on world prices.

That is why Russia refused to cut production this month. Even if its cuts did boost world prices — doubtful given the coronavirus outbreak’s huge shock to demand — that would slow the shrinkage of US shale that Moscow wants.

Shale has affected the natural gas industry even more. Exports of US liquefied natural gas now put an effective ceiling on global prices, and debates over a clean electricity push have intensified when gas prices spike.

On top of all this, there is also the renewables’ revolution, though a green revolution has not been guaranteed in the near term. Around the world, wind and solar have become ever-cheaper options to generate electricity. Storage costs have also dropped and network management improved. Even in the US, renewables are displacing coal and gas. Electrification of vehicle fleets will damp demand further, as U.S. electricity, gas, and EVs face evolving pressures.

Eliminating fossil fuel consumption completely would require sustained and costly government intervention, and reliability challenges such as coal and nuclear disruptions add to the complexity. That is far from certain. Meanwhile, though, market forces are depressing the sector’s usual profitability.

The end of oil and gas is not immediately around the corner. Still, the end of hydrocarbons as a lucrative industry is a distinct possibility. We are seeing that in dramatic form in the current oil price crash. But this collapse is merely a message from the future.

Cal ISO Warns Rolling Blackouts Possible, Calls For Conservation As Power Grid Strains

Cal ISO Flex Alert urges Southern California energy conservation as a Stage 2 emergency strains the power grid, with potential rolling blackouts during peak hours from 3 to 10 p.m., if demand exceeds supply.

 

Key Points

A statewide call to conserve power during high demand, issued by the grid operator to prevent rolling blackouts.

✅ Stage 2 emergency signals severe grid strain

✅ Peak Flex Alert hours: 3 to 10 p.m. statewide

✅ Set thermostats to 78 and avoid major appliances

 

Residents and businesses across Southern California were urged to conserve power Tuesday afternoon amid ongoing electricity inequities across the state as the manager of the state’s power grid warned rolling blackouts could be imminent for some power customers.

The California Independent System Operator (Cal ISO), which manages the state power grid, declared a Stage 2 emergency as of 2:30 p.m., indicating severe strain on the electrical system, similar to a recent grid alert in Alberta that relied on reserves.

ADVERTISING

Rolling blackouts for some customers could occur in a Stage 3 emergency, distinct from the intentional shut-offs some utilities use to reduce wildfire risk.

Cal ISO issued a statewide Flex Alert in effect from 3 to 10 p.m. Tuesday and Wednesday, with conservation considered especially critical during those hours, a concern heightened by pandemic-era grid operations this year.

Officials told reporters rolling blackouts might be avoided Tuesday evening if residents repeat the level of conservation seen Monday.
“If we can get the same sort of response we got yesterday, we can minimize this, or perhaps avoid it altogether,” Cal-ISO President/CEO Steve Berberich said, noting that some operators have even planned staff lockdowns during COVID-19 to maintain reliability.

Cal-ISO controls roughly 80% of the state’s power grid through Southern California Edison, Pacific Gas and Electric Co., with the utility recently restoring power after shut-offs in affected communities, and San Diego Gas & Electric.

Residents are urged to set thermostats at 78 in the afternoon and evening hours and avoiding the use of air conditioning and major appliances during the Flex Alert hours, as utilities like PG&E prepare for winter storms to improve resilience.
