Solar Decathlon games begin

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.

UK Offshore Wind Expansion will make wind the main power source, driving renewable energy, offshore projects, smart grids, battery storage, and interconnectors to cut carbon emissions, boost exports, and attract global investment.

Key Points

A UK strategy to scale offshore wind, integrate smart grids and storage, cut emissions and drive investment and exports

✅ 30% energy target by 2030, backed by CfD support

✅ 250m industry investment and smart grid build-out

✅ Battery storage and interconnectors balance intermittency

Plans are afoot to make wind the UKs main power source for the first time in history amid ambitious targets to generate 30 percent of its total energy supply by 2030, up from 8 percent at present.

A recently inked deal will see the offshore wind industry invest 250 million into technology and infrastructure over the next 11 years, with the government committing up to 557 million in support, under a renewable energy auction that boosts wind and tidal projects, as part of its bid to lower carbon emissions to 80 percent of 1990 levels by 2050.

Offshore wind investment is crucial for meeting decarbonisation targets while increasing energy production, says Dominic Szanto, Director, Energy and Infrastructure at JLL. The governments approach over the last seven years has been to promise support to the industry, provided that cost reduction targets were met. This certainty has led to the development of larger, more efficient wind turbines which means the cost of offshore wind energy is a third of what it was in 2012.

Boosting the wind industry

Offshore wind power has been gathering pace in the UK and has grown despite COVID-19 disruptions in recent years. Earlier this year, the Hornsea One wind farm, the worlds largest offshore generator which is located off the Yorkshire coast, started producing electricity. When fully operational in 2020, the project will supply energy to over a million homes, and a further two phases are planned over the coming decade.

Over 10 gigawatts of offshore wind either already has government support or is eligible to apply for it in the near future, following a 10 GW contract award that underscores momentum, representing over 30 billion of likely investment opportunities.

Capital is coming from European utility firms and increasingly from Asian strategic investors looking to learn from the UKs experience. The attractive government support mechanism means banks are keen to lend into the sector, says Szanto.

New investment in the UKs offshore wind sector will also help to counter the growing influence of China. The UK is currently the worlds largest offshore wind market, but by 2021 it will be outstripped by China.

Through its new deal, the government hopes to increase wind power exports fivefold to 2.6 billion per year by 2030, with the UKs manufacturing and engineering skills driving projects in growth markets in Europe and Asia and in developing countries supported by the World Bank support through financing and advisory programs.

Over the next two decades, theres a massive opportunity for the UK to maintain its industry leading position by designing, constructing, operating and financing offshore wind projects, says Szanto. Building on projects such as the Hywind project in Scotland, it could become a major export to countries like the USA and Japan, where U.S. lessons from the U.K. are informing policy and coastal waters are much deeper.

Wind-powered smart grids

As wind power becomes a major contributor to the UKs energy supply, which will be increasingly made up of renewable sources in coming decades, there are key infrastructure challenges to overcome.

A real challenge is that the UKs power generation is becoming far more decentralised, with smaller power stations such as onshore wind farms and solar parks and more prosumers residential houses with rooftop solar coupled with a significant rise in intermittent generation, says Szanto. The grid was never designed to manage energy use like that.

One potential part of the solution is to use offshore wind farms in other sites in European waters.

By developing connections between wind projects from neighbouring countries, it will create super-grids that will help mitigate intermittency issues, says Szanto.

More advanced energy storage batteries will also be key for when less energy is generated on still days. There is a growing need for batteries that can store large amounts of energy and smart technology to discharge that energy. Were going through a revolution where new technology companies are working to enable a much smarter grid.

Future smart grids, based on developing technology such as blockchain, might enable the direct trading of energy between generators and consumers, with algorithms that can manage many localised sources and, critically, ensure a smooth power supply.

Investors seeking a higher-yield market are increasingly turning to battery technology, Szanto says. In a future smart grid, for example, batteries could store electricity bought cheaply at low-usage times then sold at peak usage prices or be used to provide backup energy services to other companies.

Majors investing in the transition

Its not just new energy technology companies driving change; established oil and gas companies are accelerating spending on renewable energy. Shell has committed to $1-2 billion per year on clean energy technologies out of a $25-30 billion budget, while Equinor plans to spend 15-20 percent of its budget on renewables by 2030.

The oil and gas majors have the global footprint to deliver offshore wind projects in every country, says Szanto. This could also create co-investment opportunities for other investors in the sector especially as nascent wind markets such as the U.S., where the U.S. offshore wind timeline is still developing, and Japan evolve.

European energy giants, for example, have bid to build New Yorks first offshore wind project.

As offshore wind becomes a globalised sector, with a trillion-dollar market outlook emerging, the major fuel companies will have increasingly large roles. They have the resources to undertake the years-long, cost-intensive developments of wind projects, driven by a need for new business models as the world looks beyond carbon-based fuels, says Szanto.

Oil and gas heavyweights are also making wind, solar and energy storage acquisitions BP acquired solar developer Lightsource and car-charging network Chargemaster, while Shell spent $400 million on solar and battery companies.

The public perception is that renewable energy is niche, but its now a mainstream form of energy generation., concludes Szanto.

Every nation in the world is aligned in wanting a decarbonised future. In terms of electricity, that means renewable energy and for offshore wind energy, the outlook is extremely positive.

Ontario Renewable Energy Cancellations highlight Doug Ford's move to scrap wind turbine contracts, citing electricity rate relief and taxpayer savings, while critics, the NDP, and industry warn of job losses, termination fees, and auditor scrutiny.

Key Points

Ontario's termination of renewable contracts, defended as cost and rate relief, faces disputes over savings and jobs.

✅ PCs cite electricity rate relief and taxpayer savings.

✅ Critics warn of job losses and termination fees.

✅ Auditor inquiry sought into contract cancellation costs.

Ontario Premier Doug Ford, whose new stance on wind power has drawn attention, said Thursday he is “proud” of his decision to tear up hundreds of renewable energy deals, a move that his government acknowledges could cost taxpayers more than $230 million.

Ford dismissed criticism that his Progressive Conservatives are wasting public money, telling a news conference that the cancellation of 750 contracts signed by the previous Liberal government will save cash, even as Ontario moves to reintroduce renewable energy projects in the coming years.

“I’m so proud of that,” Ford said of his decision. “I’m proud that we actually saved the taxpayers $790 million when we cancelled those terrible, terrible, terrible wind turbines that really for the last 15 years have destroyed our energy file.”

Later Thursday, Ford went further in defending the cancelled contracts, saying “if we had the chance to get rid of all the wind mills we would,” though a court ruling near Cornwall challenged such cancellations.

The NDP first reported the cost of the cancellations Tuesday, saying the $231 million figure was listed as “other transactions”, buried in government documents detailing spending in the 2018-2019 fiscal year.

The Progressive Conservatives have said the final cost of the cancellations, which include the decommissioning of a wind farm already under construction in Prince Edward County, Ont., has yet to be established, amid warnings about wind project cancellation costs from developers.

The government has said it tore up the deals because the province didn’t need the power and it was driving up electricity rates, and the decision will save millions over the life of the contracts. Industry officials have disputed those savings, saying the cancellations will just mean job losses for small business, and ignore wind power’s growing competitiveness in electricity markets.

NDP Leader Andrea Horwath has asked Ontario’s auditor general to investigate the contracts and their termination fees, amid debates over Ontario’s electricity future among leadership contenders. She called Ford’s remarks on Thursday “ridiculous.”

“Every jurisdiction around the world is trying to figure out how to bring more renewables onto their electricity grids,” she said. “This government is taking us backwards and costing us at the very least $231 million in tearing these energy contracts.”

At the federal level, a recent green electricity contract with an Edmonton company underscores that shift.

Urban Piezoelectric Energy Textiles capture wind-driven motion on tunnels, bridges, and facades, enabling renewable microgeneration for smart cities with decentralized power, resilient infrastructure, and flexible lamellae sheets that harvest airflow vibrations.

Key Points

Flexible piezoelectric sheets that convert urban wind and vibration into electricity on tunnels, bridges, and facades.

✅ Installed on London Crossrail to test airflow energy capture

✅ Flexible lamellae panels retrofit tunnels, bridges, facades

✅ Supports decentralized, resilient urban microgrids

Charlotte Slingsby and her startup Moya Power are researching piezo-electric textiles that gain energy from movement, similar to advances like a carbon nanotube energy harvester being explored by materials researchers. It seems logical that Slingsby originally came from a city with a reputation for being windy: “In Cape Town, wind is an energy source that you cannot ignore,” says the 27-year-old, who now lives in London.

Thanks to her home city, she also knows about power failures. That’s why she came up with the idea of not only harnessing wind as an alternative energy source by setting up wind farms in the countryside or at sea, but also for capturing it in cities using existing infrastructure.

The problem

The United Nations estimates that by 2050, two thirds of the world’s population will live in cities. As a result, the demand for energy in urban areas will increase dramatically, spurring interest in nighttime renewable technology that can operate when solar and wind are variable. Can the old infrastructure grow fast enough to meet demand? How might we decentralise power generation, moving it closer to the residents who need it?

For a pilot project, she has already installed grids of lamellae-covered plastic sheets in tunnels on London Crossrail routes; the draft in the tube causes the protrusions to flutter, which then generates electricity.

“If we all live in cities that need electricity, we need to look for new, creative ways to generate it, including nighttime solar cells that harvest radiative cooling,” says Slingsby, who studied design and engineering at Imperial College and the Royal College of Art. “I wanted to create something that works in different situations and that can be flexibly adapted, whether you live in an urban hut or a high-rise.”

The yield is low compared to traditional wind power plants and is not able to power whole cities, but Slingsby sees Moya Power as just a single element in a mixture of urban energy sources, alongside approaches like gravity power that aid grid decarbonization.

In the future, Slingsby’s invention could hang on skyscrapers, in tunnels or on bridges – capturing power in the windiest parts of the city, alongside emerging air-powered generators that draw energy from humidity. The grey concrete of tunnels and urban railway cuttings could become our cities’ most visually appealing surfaces...

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.

Texas Power Grid Blackouts loom as ERCOT forecasts record air conditioning load, tight reserve margins, peak demand spikes, and rising natural gas prices; heatwaves could trigger brownouts without added solar, storage, and demand response.

Key Points

Texas Power Grid Blackouts are outages when AC-driven peak demand and ERCOT reserves outstrip supply during heatwaves.

✅ ERCOT forecasts record AC load and tight reserve margins.

✅ Coal retirements cut capacity; gas and solar additions lag.

✅ Peak prices, brownouts likely without storage and demand response.

U.S. Air conditioning related electricity usage will break records and may cause blackouts across the U.S. and in Texas this summer. Power grid operators are forecasting that electricity supplies will exceed demands during the summer months.

Most of Texas will face severe electricity shortages because of hot temperatures, air conditioning, and a strong economy, with millions at risk of electricity shut-offs during extreme heat, Bill Magness the president of the Electric Reliability Council of Texas (ERCOT) told the Associated Press. Magness thinks the large numbers people moving to Texas for retirement will increase the demand for air conditioning and electricity use. Retired people are more likely to be home during the day when temperatures are high – so they are more likely to turn up the air conditioner.

Around 50% of all electricity in Texas is used for air conditioning and 100% of homes in Texas have air conditioners, Forbes reported. That means just a few hot days can strain the grid and a heatwave can trigger brownouts and blackouts, in a system with more blackouts than other developed countries on average.

The situation was made worse by Vistra Energy’s decision to close more coal-fired power plants last year, The Austin American Statesman reported. The closed plants; Big Brown, Sadow, and Monticello, generated around 4,100 megawatts (4.1 million watts) of electricity, enough generation capacity to power two million homes, The Waco Herald-Tribune reported.

Texas Electric Grid Might Not Meet Demand

Texas’s grid has never operated without those plants will make this summer a test of its capacity. Texas only has a 6% reserve of electricity that might fall will because of problems like downed lines or a power plant going offline.

A Vistra subsidiary called Luminant has added around 8,000 megawatts of generation capacity from natural-gas burning plants, The Herald-Tribune reported. Luminant also plans to open a giant solar power plant in Texas to increase grid capacity.

The Texas grid already reached peak capacity in May because of unexpectedly high demand and technical problems that reflect more frequent outages in many states, Houston Public Media reported. Grid capacity fell because portions of the system were offline for maintenance.

Some analysts have suggested starting schools after Labor Day to shift peak August demand, potentially easing stress on the grid.

Electricity Reserves are Tight in Texas

Electricity reserves will be very tight on hot summer days in Texas this summer, Magness predicted. When the thermometer rises, people crank up the air conditioner which burns more electricity.

The grid operator ERCOT anticipates that Texas will need an additional 1,600 megawatts of electricity this summer, but record-high temperatures can significantly increase the demand. If everything is running correctly, Texas’s grid can produce up to 78,184 megawatts of electricity.

“The margin between absolute peak power usage and available peak supply is tighter than in years past,” Andrew Barlow, a spokesman for Texas’s Public Utility Commission admitted.

Around 90% of Texas’s grid has enough generating capacity, ERCOT estimated. That means 10% of Texas’s power grid lacks sufficient generating capacity which increases the possibility of blackouts.

Even if the electricity supply is adequate electricity prices can go up in Texas because of higher natural gas prices, Forbes reported. Natural gas prices might go up over the summer because of increased electricity demands. Texas uses between 8% and 9% of America’s natural gas supply to generate electricity for air conditioning in the summer.

Be Prepared For Blackouts This Summer.

Texas’s problems might affect other regions including neighboring states such as Oklahoma, Arkansas, Louisiana, and New Mexico and parts of Mexico, as lawmakers push to connect Texas’s grid to the rest of the nation to improve resilience because those areas are connected to the same grid. Electricity from states like Colorado might be diverted to Texas in case of power shortages there.

Beyond the U.S., Canadian electricity grids are increasingly exposed to harsh weather that can ripple across markets as well.

Home and business owners can avoid summer blackouts by tapping sources of Off-Grid electricity. The two best sources are backup battery storage and solar panels which can run your home or business if the grid runs dry.

If you have family members with health problems who need air conditioning, or you rely on a business or freelance work that requires electricity for income, backup power is vital. Those who need backup electricity for their business should be able to use the expense of installing it as a tax deduction.

Having backup electricity available might be the only way for Texans to keep cool this summer.
