Iran Power Outage Protests surge as electricity blackouts, drought, and a looming heat wave spark unrest in Tehran, Shiraz, and more, with chants against leadership, strikes, and sanctions-driven economic pressures mounting.

Key Points

Protests across Iran over blackouts, drought, and economic strain challenge authorities and demand accountability.

✅ Rolling blackouts blamed on drought, heat wave, and surging demand.

✅ Chants target leadership amid strikes and wage, water shortages.

✅ Legitimacy questioned after low-turnout election and sanctions.

There have been protests in a number of cities in Iran amid rising public anger over widespread electricity blackouts.

Videos on social media appeared to show crowds in Shar-e Rey near Tehran, Shiraz, Amol and elsewhere overnight.

Some people can be heard shouting "Death to the dictator" and "Death to Khamenei" - a reference to Supreme Leader Ayatollah Ali Khamenei.

The government has apologised for the blackouts, which it has blamed on a severe drought and high demand.

Elsewhere, similar outages have had political repercussions, as a widespread power outage in Taiwan prompted a minister's resignation earlier this year.

President Hassan Rouhani explained in televised remarks on Tuesday morning that the drought meant most of the country's hydroelectric power plants were not operating, placing more pressure on thermal power plants, and that electricity consumption had surged as people used air conditioning to cope with the intense summer heat.

"I apologise to our dear people who have faced problems and suffering in the past few days and I urge them to co-operate [by cutting their electricity use]. People complain about power outages and they are right," Mr Rouhani said.

A video that has gone viral in recent days shows a woman complaining about the blackouts and corruption at a government office in the northern city of Gorgan and demanding that her comments be conveyed to "higher-ups like Mr Rouhani". "The only thing you have done is forcing hijab on us," she shouts.

The president has promised that the government will seek to resolve the problems within the next two or three weeks.

However, a power sector spokesman warned on Monday that consumption was exceeding the production capacity of Iran's power plants by 11GW, and said a "looming heat wave" could make the situation worse, as seen in Iraq's summer electricity crunch this year.

Iranians have also been complaining about water shortages and the non-payment of wages by some local authorities, while thousands of people working in Iran's oil industry have been on strike over pay and conditions, as officials discuss further energy cooperation with Iraq to ease supply pressures.

There was already widespread discontent at government corruption and the economic hardship caused by sanctions that were reinstated when the US abandoned a nuclear deal with Iran three years ago, even as Iran supplies about 40% of Iraq's electricity through cross-border sales.

Analysts say that after the historically low turnout in last month's presidential election, when more than half of the eligible voters stayed at home, the government is facing a serious challenge to its legitimacy.

Mr Rouhani will be succeeded next month by Ebrahim Raisi, a hard-line cleric close to Ayatollah Khamenei who won 62% of the vote after several prominent contenders were disqualified, while Iran finalizes power grid deals with Iraq to bolster regional ties.

The 60-year-old former judiciary chief has presented himself as the best person to combat corruption and solve Iran's economic problems, including ambitions to transmit electricity to Europe as a regional power hub.

But many Iranians and human rights activists have pointed to his human rights record, accusing him of playing a role in the executions of thousands of political prisoners in the 1980s and in the deadly crackdowns on mass anti-government protests in 2009 and 2019.

Houston Power Outage Heatwave intensifies a prolonged blackout, straining the grid and infrastructure resilience; emergency response, cooling centers, and power restoration efforts race to protect vulnerable residents amid extreme temperatures and climate risks.

Key Points

A multi-day blackout and heatwave straining Houston's grid, limiting cooling, and prompting emergency response.

✅ Fourth day without power amid dangerous heat

✅ Grid failures expose infrastructure vulnerabilities

✅ Cooling centers, aid groups support vulnerable residents

Houston is enduring significant frustration and hardship as a power outage stretches into its fourth day amid a sweltering heatwave. The extended blackout has exacerbated the challenges faced by residents in one of the nation’s largest and most dynamic cities, underscoring the critical need for reliable infrastructure and effective emergency response systems.

The power outage began early in the week, coinciding with a severe heatwave that has driven temperatures to dangerous levels. With the city experiencing some of the highest temperatures of the year, the lack of electricity has left residents without essential cooling, contributing to widespread discomfort and health risks. The heatwave has placed an added strain on Houston's already overburdened power grid, which has struggled to cope with the soaring demand for air conditioning and cooling.

The prolonged outage has led to escalating frustration among residents. Many households are grappling with sweltering indoor temperatures, leading to uncomfortable living conditions and concerns about the impact on vulnerable populations, including the elderly, young children, and individuals with pre-existing health conditions. The lack of power has also disrupted daily routines, as morning routine disruptions in London demonstrate, including access to refrigeration for food, which has led to spoilage and further complications.

Emergency services and utility companies have been working around the clock to restore power, but progress has been slow, echoing how Texas utilities struggled to restore power during Hurricane Harvey, as crews contended with access constraints. The complexity of the situation, combined with the high demand for repairs and the challenging weather conditions, has made it difficult to address the widespread outages efficiently. As the days pass, the situation has become increasingly dire, with residents growing more impatient and anxious about when they might see a resolution.

Local officials and utility providers have been actively communicating with the public, providing updates on the status of repairs and efforts to restore power. However, the communication has not always been timely or clear, leading to further frustration among those affected. The sense of uncertainty and lack of reliable information has compounded the difficulties faced by residents, who are left to manage the impacts of the outage with limited guidance.

The situation has also raised questions about the resilience of Houston’s power infrastructure. The outage has highlighted vulnerabilities in the city's energy grid, similar to how a recent windstorm caused significant outages elsewhere, which has faced previous challenges but has not experienced an extended failure of this magnitude in recent years. The inability of the grid to withstand the extreme heat and maintain service during a critical time underscores the need for infrastructure improvements and upgrades to better handle similar situations in the future.

In response to the crisis, community organizations and local businesses have stepped up to provide support to those in need, much like Toronto's cleanup after severe flooding mobilized volunteers and services, in order to aid affected residents. Cooling centers have been established to offer relief from the heat, providing a respite for individuals who are struggling to stay cool at home. Additionally, local food banks and charitable organizations are distributing essential supplies to those affected by food spoilage and other challenges caused by the power outage.

The power outage and heatwave have also sparked broader discussions about climate resilience and preparedness. Extreme weather events and prolonged heatwaves are becoming increasingly common due to climate change, as strong winds knocked out power across the Miami Valley recently, raising concerns about how cities and infrastructure systems can adapt to these new realities. The current situation in Houston serves as a stark reminder of the importance of investing in resilient infrastructure and developing comprehensive emergency response plans to mitigate the impacts of such events.

As the outage continues, there is a growing call for improved strategies to manage power grid failures, with examples like the North Seattle outage affecting 13,000 underscoring the need, and better support for residents during crises. Advocates are urging for a reevaluation of emergency response protocols, increased investment in infrastructure upgrades, and enhanced communication systems to ensure that the public receives timely and accurate information during emergencies.

In summary, Houston's power outage, now extending into its fourth day amid extreme heat, has caused significant frustration and hardship for residents. The prolonged disruption has underscored the need for more resilient energy infrastructure, as seen when power outages persisted for hundreds in Toronto, and effective emergency response measures. With temperatures soaring and the situation continuing to unfold, the city faces a critical challenge in restoring power, managing the impacts on its residents, and preparing for future emergencies. The crisis highlights broader issues related to infrastructure resilience and climate adaptation, emphasizing the need for comprehensive strategies to address and mitigate the effects of extreme weather events.

California Blackouts expose grid reliability risks as PG&E deenergizes lines during high winds. Mandated solar and wind displace dispatchable natural gas, straining ISO load balancing, transmission maintenance, and battery storage planning amid escalating wildfire liability.

Key Points

California grid shutoffs stem from wildfire risk, renewables, and deferred transmission maintenance under mandates.

✅ PG&E deenergizes lines to reduce wildfire ignition during high winds.

✅ Mandated solar and wind displace dispatchable gas, raising balancing costs.

✅ Storage, reliability pricing, and grid upgrades are needed to stabilize supply.

California is again facing widespread blackouts this season. Politicians are scrambling to assign blame to Pacific Gas & Electric (PG&E) a heavily regulated utility that can only do what the politically appointed regulators say it can do. In recent years this has meant building a bunch of solar and wind projects, while decommissioning reliable sources of power and scrimping on power line maintenance and upgrades.

The blackouts are connected with the legal liability from old and improperly maintained power lines being blamed for sparking fires—in hopes that deenergizing the grid during high winds reduces the likelihood of fires. 

How did the land of Silicon Valley and Hollywood come to have developing world electricity?

California’s Democratic majority, from Gov. Gavin Newsom to the solidly progressive legislature, to the regulators they appoint, have demanded huge increases in renewable energy. Renewable electricity targets have been pushed up, and policymakers are weighing a revamp of electricity rates to clean the grid, with the state expected to reach a goal of 33% of its power from renewable sources, mostly solar and wind, by next year, and 60% of its electricity from renewables by 2030.

In 2018, 31% of the electricity Californians purchased at the retail level came from approved renewables. But when rooftop solar is added to the mix, about 34% of California’s electricity came from renewables in 2018. Solar photovoltaic (PV) systems installed “behind-the-meter” (BTM) displace utility-supplied generation, but still affect the grid at large, as electricity must be generated at the moment it is consumed. PV installations in California grew 20% from 2017 to 2018, benefiting from the state’s Self-Generation Incentive Program that offers hefty rebates through 2025, as well as a 30% federal tax credit.

Increasingly large amounts of periodic, renewable power comes at a price—the more there is, the more difficult it is to keep the power grid stable and energized. Since electricity must be consumed the instant it is generated, and because wind and solar produce what they will whenever they do, the rest of the grid’s power producers—mostly natural gas plants—have to make up any differences between supply and immediate demand. This load balancing is vital, because without it, the grid will crash and widespread blackouts will ensue.

California often produces a surplus of mandated solar and wind power, generated for 5 to 8 cents per kilowatt hour. This power displaces dispatchable power from natural gas, coal and nuclear plants, resulting in reliable power plants spending less time online and driving up electricity prices as the plants operate for fewer hours of the day. Subsidized and mandated solar power, along with a law passed in California in 2006 (SB 1638) that bans the renewal of coal-fired power contracts, has placed enormous economic pressure on the Western region’s coal power plants—among them, the nation’s largest, Navajo Generating Station. As these plants go off line, the Western power grid will become increasingly unstable. Eventually, the states that share their electric power in the Western Interconnect may have to act to either subsidize dispatchable power or place a value on reliability—something that was taken for granted in the growth of the America’s electrical system and its regulatory scheme.

California law regarding electricity explicitly states that “a violation of the Public Utilities Act is a crime” and that it is “…the intent of the Legislature to provide for the evolution of the ISO (California’s Independent System Operator—the entity that manages California’s grid) into a regional organization to promote the development of regional electricity transmission markets in the western states.” In other words, California expects to dictate how the Western grid operates.

One last note as to what drives much of California’s energy policy: politics. California State Senator Kevin de León (the author served with him in the State Assembly) drafted SB 350, the Clean Energy and Pollution Reduction Act. It became law in 2015. Sen. de León followed up with SB 100 in 2018, signed into law weeks before the 2018 election. SB 100 increased California’s renewable portfolio standard to 60% by 2030 and further requires all the state’s electricity to come from carbon-free sources by 2045, a capstone of the state’s climate policies that factor into the blackout debate.  

Sen. de León used his environmental credentials to burnish his run for the U.S. Senate against Sen. Dianne Feinstein, eventually capturing the endorsements of the California Democratic Party and billionaire environmentalist Tom Steyer, now running for president. Feinstein and de León advanced to the general in California’s jungle primary, where Feinstein won reelection 54.2% to 45.8%.

De León may have lost his race for the U.S. Senate, but his legacy will live on in increasingly unaffordable electricity and blackouts, not only in California, but in the rest of the Western United States—unless federal or state regulators begin to place a value on reliability. This could be done by requiring utility scale renewable power providers to guarantee dispatchable power, as policymakers try to avert a looming shortage of firm capacity, either through purchase agreements with thermal power plants or through the installation of giant and costly battery farms or other energy storage means.

Great Northern Transmission Line delivers 250 MW of carbon-free hydropower from Manitoba Hydro, strengthening Midwest grid reliability, enabling wind storage balancing, and advancing Minnesota Power's EnergyForward strategy for cleaner, renewable energy across the region.

Key Points

A 500 kV cross-border line delivering 250 MW of carbon-free hydropower, strengthening reliability and enabling renewables.

✅ 500 kV, 224-mile line from Manitoba to Minnesota

✅ Delivers 250 MW hydropower via ALLETE-Minnesota Power

✅ Enables wind storage and grid balancing with Manitoba Hydro

Minnesota Power, a utility division of ALLETE Inc. (NYSE:ALE), has energized its Great Northern Transmission Line, bringing online an innovative delivery and storage system for renewable energy that spans two states and one Canadian province, similar to the Maritime Link project in Atlantic Canada.

The 500 kV line is now delivering 250 megawatts of carbon-free hydropower from Manitoba, Canada, to Minnesota Power customers.

Minnesota Power completed the Great Northern Transmission Line (GNTL) in February 2020, ahead of schedule and under budget. The 224-mile line runs from the Canadian border in Roseau County to a substation near Grand Rapids, Minnesota. It consists of 800 tower structures which were fabricated in the United States and used 10,000 tons of North American steel. About 2,200 miles of wire were required to install the line's conductors. The GNTL also is contributing significant property tax revenue to local communities along the route.

"This is such an incredible achievement for Minnesota Power, ALLETE, and our region, and is the culmination of a decade-long vision brought to life by our talented and dedicated employees," said ALLETE President and CEO Bethany Owen. "The GNTL will help Minnesota Power to provide our customers with 50 percent renewable energy less than a year from now. As part of our EnergyForward strategy, it also strengthens the grid across the Midwest and in Canada, enhancing reliability for all of our customers."

With the GNTL energized and connected to Manitoba Hydro's recently completed Manitoba-Minnesota Transmission Project at the border, the companies now have a unique "wind storage" mechanism that quickly balances energy supply and demand in Minnesota and Manitoba, and enables a larger role for renewables in the North American energy grid.

The GNTL and its delivery of carbon-free hydropower are important components of Minnesota Power's EnergyForward strategy to transition away from coal and add renewable power sources while maintaining reliable and affordable service for customers, echoing interties like the Maritime Link that facilitate regional power flows. It also is part of a broader ALLETE strategy to advance and invest in critical regional transmission and distribution infrastructure, such as the TransWest Express transmission project, to ensure grid integrity and enable cleaner energy to reduce carbon emissions.

"The seed for this renewable energy initiative was planted in 2008 when Minnesota Power proposed purchasing 250 megawatts of hydropower from Manitoba Hydro. Beyond the transmission line, it also included a creative asset swap to move wind power from North Dakota to Minnesota, innovative power purchase agreements, and a remarkable advocacy process to find an acceptable route for the GNTL," said ALLETE Executive Chairman Al Hodnik. "It marries wind and water in a unique connection that will help transform the energy landscape of North America and reduce carbon emissions related to the existential threat of climate change."

Minnesota Power and Manitoba Hydro, a provincial Crown Corporation, coordinated on the project from the beginning, navigating National Energy Board reviews along the way. It is based on the companies' shared values of integrity, environmental stewardship and community engagement.

"The completion of Minnesota Power's Great Northern Transmission Line and our Manitoba-Minnesota Transmission Project is a testament to the creativity, perseverance, cooperation and skills of hundreds of people over so many years on both sides of the border," said Jay Grewal, president and CEO of Manitoba Hydro. "Perhaps even more importantly, it is a testament to the wonderful, longstanding relationship between our two companies and two countries. It shows just how much we can accomplish when we all work together toward a common goal."

Minnesota Power engaged federal, state and local agencies; the sovereign Red Lake Nation and other tribes, reflecting First Nations involvement in major transmission planning; and landowners along the proposed routes beginning in 2012. Through 75 voluntary meetings and other outreach forums, a preferred route was selected with strong support from stakeholders that was approved by the Minnesota Public Utilities Commission in April 2016.

A four-year state and federal regulatory process culminated in late 2016 when the federal Department of Energy approved a Presidential Permit for the GNTL, similar to the New England Clean Power Link process, needed because of the international border crossing. Construction of the line began in early 2017.

"A robust stakeholder process is essential to the success of any project, but especially when building a project of this scope," Owen said. "We appreciated the early engagement and support from stakeholders, local communities and tribes, agencies and regulators through the many approval milestones to the completion of the GNTL."

Courtyard by Marriott Lancaster Solar Array delivers 100% renewable electricity via photovoltaic panels at Greenfield Corporate Center, Pennsylvania, a High Hotels and Marriott sustainability initiative reducing grid demand and selling excess power for efficient operations.

Key Points

A $1.5M PV installation powering the 133-room hotel with 100% renewable electricity in Greenfield Center, Lancaster.

✅ 2,700 PV panels generate 1,239,000 kWh annually

✅ First Marriott in the US with 100% solar electricity

✅ $504,900 CFA grant; excess power sold to the utility

High Hotels Ltd., a hotel developer and operator, recently announced it is installing a $1.5 million solar array that will generate 100% of the electrical power required to operate one of its existing hotels in Greenfield Corporate Center. The completed installation will make the 133-room Courtyard by Marriott-Lancaster the first Marriott-branded hotel in the United States with 100% of its electricity needs generated from solar power. It is also believed to be the first solar array in the country installed for the sole purpose of generating 100% of the electricity needs of a hotel, mirroring how other firms are commissioning their first solar power plant to meet sustainability goals.

“This is an exciting approach to addressing our energy needs that aligns very well with High’s commitment to environmental stewardship,”

“We’ve been advancing many environmentally responsible practices across our hotel portfolio, including converting the interior and exterior lighting at the Lancaster Courtyard to LED, which will lower electricity demand by 15%,” said Russ Urban, president of High Hotels. “Installing solar is another important step in this progression, and we will look to apply lessons from this as we expand our portfolio of premium select-service hotels.”

The Lancaster-based hotel developer, owner and operator is working in partnership with Marriott International Inc. to realize this vision, in step with major brands announcing new clean energy projects across their portfolios.

The installation of more than 2,700 ballasted photovoltaic panels will fill an area more than two football fields in size. After evaluating several on-site and near-site alternatives, High Hotels decided to install the solar array on the roof of a nearby building in Greenfield Corporate Center. Using the existing roof saves more than three acres of open land and has additional aesthetic benefits, aligning with recommendations for solar farms under consideration by local planners. The solar array will produce 1,239,000 kWh of power for the hotel, which consumes 1,177,000 kWh. Any excess power will be sold to the utility, though affordable solar batteries are making on-site storage increasingly feasible.

High Hotels received a grant of $504,900 from the Commonwealth Financing Authority (CFA) through the Solar Energy Program to complete the project. An independent agency of the Department of Community and Economic Development (DCED), the CFA is responsible for evaluating projects and awarding funds for a variety of economic development programs, including the Solar Energy Program and statewide initiatives like solar-power subscriptions that broaden access. The project will receive a solar renewable energy credit which will be conveyed to the CFA to provide the agency with more funds to offer grants in the future.

“This is a cutting-edge project that is exactly the kind we are looking for to promote the generation and use of solar energy,” said DCED Secretary Dennis Davin. “I am very pleased that the first Marriott in the US to receive 100% of its electric needs through renewable solar energy is located right here in Central Pennsylvania.” Secretary Davin also serves as chairman of the CFA’s board.

Panels for the solar array will be Q Cells manufactured by Hanwha Cells Co., Ltd., headquartered in Seoul, South Korea. Ephrata, Pa.-based Meadow Valley Electric Inc. will install the array in the second and third quarters of 2018 with commissioning targeted for September 2018.

UK Smart Export Guarantee enables households to sell surplus solar energy to suppliers, with dynamic export tariffs, grid payments, and battery-friendly incentives, boosting local renewable generation, microgeneration uptake, and decarbonisation across Britain.

Key Points

UK Smart Export Guarantee pays homes for exporting surplus solar power to the grid via supplier tariffs.

✅ Suppliers must pay households for exported kWh.

✅ Dynamic tariffs incentivize daytime solar generation.

✅ Batteries boost self-consumption and grid flexibility.

Britain’s biggest energy companies will have to buy renewable energy from their own customers through community-generated green electricity models under new laws to be introduced this week.

Homeowners who install new rooftop solar panels from 1 January 2020 will be able to lower their bills as many seek to cut soaring bills by selling the energy they do not need to their supplier.

A record was set at noon on a Friday in May 2017, when solar energy supplied around a quarter of the UK’s electricity, and a recent award that adds 10 GW of renewables indicates further growth.

However, solar panel owners are not always at home on sunny days to reap the benefit. The new rules will allow them to make money if they generate electricity for the grid.

Some 800,000 householders with solar panels already benefit from payments under a previous scheme. However, the subsidies were controversially scrapped by the government in April, with similar reduced credits for solar owners seen in other regions, causing the number of new installations to fall by 94% in May from the month before.

Labour accused the government last week of “actively dismantling” the solar industry. The sector will still struggle this summer as the change does not come in for another seven months, so homeowners have no incentive to buy panels this year.

Chris Skidmore, the minister for energy and clean growth, said the government wanted to increase the number of small-scale generators without adding the cost of subsidies to energy bills. “The future of energy is local and the new smart export guarantee will ensure households that choose to become green energy generators will be guaranteed a payment for electricity supplied to the grid,” he said. The government also hopes to encourage homes with solar panels to install batteries to help manage excess solar power on networks.

Greg Jackson, the founder of Octopus Energy, said: “These smart export tariffs are game-changing when it comes to harnessing the power of citizens to tackle climate change”.

A few suppliers, including Octopus, already offer to buy solar power from their customers, often setting terms for how solar owners are paid that reflect market conditions.

“They mean homes and businesses can be paid for producing clean electricity just like traditional generators, replacing old dirty power stations and pumping more renewable energy into the grid. This will help bring down prices for everyone as we use cheaper power generated locally by our neighbours,” Jackson said.

Léonie Greene, a director at the Solar Trade Association, said it was “vital” that even “very small players” were paid a fair price. “We will be watching the market like a hawk to see if competitive offers come forward that properly value the power that smart solar homes can contribute to the decarbonising electricity grid,” she said.
