Iberdrola to install Spain's first smart grid in Castellon

UK Coal-Free Electricity Record highlights rapid growth in renewables as National Grid phases out coal; wind, solar, and offshore projects surge, green tariffs expand, and energy comparison helps consumers switch to cheaper, cleaner deals.

Key Points

Britain's longest coal-free run, enabled by renewables, lower demand, and grid shifts for cheaper, greener tariffs.

✅ Record set after two months without coal-fired generation

✅ Renewables outpace fossil fuels; wind and solar dominate

✅ Green tariffs expand; prices at three-year lows

On Wednesday 10 June, Britain hit a significant landmark: the UK went for two full months without burning coal to generate power – that's the longest period since the 1880s, following earlier milestones such as a full week without coal power in the recent past.

According to the National Grid, Britain has now run its electricity network without burning coal since midnight on the 9 April. This coal-free period has beaten the country’s previous record of 18 days, six hours and 10 minutes, which was set in June 2019, even though low-carbon generation stalled in 2019 according to analyses.

With such a shift in Britain’s drive for renewables and lower electricity demand following the coronavirus lockdown, as Britain recorded its cleanest electricity during lockdown to date, now may be the perfect time to do an online energy comparison and switch to a cheaper, greener deal.

Only a decade ago, around 40 per cent of Britain’s electricity came from coal generation, but since then the country has gradually shifted towards renewable energy, with the coal share at record lows in the system today. When Britain was forced into lockdown in response to the coronavirus pandemic, electricity demand dropped sharply, and the National Grid took the four remaining coal-fired plants off the network.

Over the past 10 years, Britain has invested heavily in renewable energy. Back in 2010, only 3 per cent of the country's electricity came from wind and solar, and many people remained sceptical. However, now, the UK has the biggest offshore wind industry in the world. Plus, last year, construction of the world’s single largest wind farm was completed off the coast of Yorkshire.

At the same time, Drax – Britain’s biggest power plant – has started to switch from burning coal to burning compressed wooden pellets instead, reflecting the UK's progress as it keeps breaking its coal-free energy record again across the grid. By this time next year, the plant hopes to have phased out coal entirely.

So far this year, renewables have generated more power than all fossil fuels put together, the BBC reports, and the energy dashboard shows the current mix in real time. Renewables have been responsible for 37 per cent of electricity supplied to the network, with wind and solar surpassing nuclear for the first time, while fossil fuels have accounted for 35 per cent. During the same period, nuclear accounted for 18 per cent and imports made up the remaining 10 per cent.

What does this mean for consumers?

As the country’s electricity supply moves more towards renewables, customers have more choice than ever before. Most of the ‘Big Six’ energy companies now have tariffs that offer 100 per cent green electricity. On top of this, specialist green energy suppliers such as Bulb, Octopus and Green Energy UK make it easier than ever to find a green energy tariff.

The good news is that our energy comparison research suggests that green energy doesn’t have to cost you more than a traditional fixed-price energy contract would. In fact, some of the cheapest energy suppliers are actually green companies.

At present, energy bills are at three-year lows, which means that now is the perfect time to switch supplier. As prices remain low and renewables begin to dominate the marketplace, more switchers will be drawn to green energy deals than ever before.

However, if you’re interested in choosing a green energy supplier, make sure that you look at the company's fuel mix. This way, you’ll be able to see whether they are guaranteeing the usage of green energy, or whether they’re just offsetting your usage. All suppliers must report how their energy is generated to Ofgem, so you’ll easily be able to compare providers.

You may find that you pay more for a supplier that generates its own energy from renewables, or pay less if the supplier simply matches your usage by buying green energy. You can decide which option is right for you after comparing the prices.

Russia-Ukraine Energy War disrupts infrastructure, oil, gas, and electricity, triggering supply shocks, price spikes, and inflation. Global markets face volatility, import risks, and cybersecurity threats, underscoring energy security, grid resilience, and diversified supply.

Key Points

It is Russia's strategic targeting of Ukraine's energy system to disrupt supplies, raise prices, and hit global markets.

✅ Attacks weaponize energy to strain Ukraine and allies

✅ Supply shocks risk oil, gas, and electricity price spikes

✅ Urgent need for cybersecurity, grid resilience, diversification

Russia's targeting of Ukraine's energy infrastructure has unleashed an "energy war" that could lead to widespread price increases, supply disruptions, and ripple effects throughout the global energy market, felt across the continent, with warnings of Europe's energy nightmare taking shape.

This highlights the unprecedented scale and severity of the attacks on Ukrainian energy infrastructure. These attacks have disrupted power supplies, prompting increased electricity imports to keep the lights on, hindered oil and gas production, and damaged refineries, impacting Ukraine and the broader global energy system.

Energy as a Weapon

Experts claim that Russia's deliberate attacks on Ukraine's energy infrastructure represent a strategic escalation, amid energy ceasefire violations alleged by both sides, demonstrating the Kremlin's willingness to weaponize energy as part of its war effort. By crippling Ukraine's energy system, Russia aims to destabilize the country, inflict suffering on civilians, and undermine Western support for Ukraine.

Impacts on Global Oil and Gas Markets

The ongoing attacks on Ukraine's energy infrastructure could significantly impact global oil and gas markets, leading to supply shortages and dramatic price increases, even as European gas prices briefly returned to pre-war levels earlier this year, underscoring extreme volatility. Ukraine's oil and gas production, while not massive in global terms, is still significant, and its disruption feeds into existing anxieties about global energy supplies already affected by the war.

Ripple Effects Beyond Ukraine

The impacts of the "energy war" won't be limited to Ukraine or its immediate neighbours. Price increases for oil, gas, and electricity are expected worldwide, further fueling inflation and exacerbating the global cost of living crisis.  Additionally, supply disruptions could disproportionately affect developing nations and regions heavily dependent on energy imports, making targeted energy security support to Ukraine and other vulnerable importers vital.

Vulnerability of Energy Infrastructure

The attacks on Ukraine highlight the vulnerability of critical energy infrastructure worldwide, as the country prepares for winter under persistent threats. The potential for other state or non-state actors to use similar tactics raises concerns about security and long-term stability in the global energy sector.

Strengthening Resilience

Experts emphasize the urgent need for global cooperation in strengthening the resilience of energy infrastructure. Investments in cybersecurity, diverse energy sources, and decentralized grids are crucial for mitigating the risks of future attacks, with some arguing that stepping away from fossil fuels would improve US energy security over time. International cooperation will be key in identifying vulnerable areas and providing aid to nations whose infrastructure is under threat.

The Unpredictable Future of Energy

The "energy war" unleashed by Russia has injected a new level of uncertainty into the global energy market. In addition to short-term price fluctuations and supply issues, the conflict could accelerate the long-term transition towards renewable energy sources and reshape how nations approach energy security.

National Grid power supply warning highlights electricity shortage risks amid low wind output, generator outages, and cold weather, reducing capacity margins and grid stability; considering demand response and reserve power to avoid blackout risk.

Key Points

An alert that reduced capacity from low wind and outages requires actions to maintain UK grid stability.

✅ Low wind output and generator outages reduce capacity margins

✅ ESO exploring demand response and reserve generation options

✅ Aim: maintain grid stability and avoid blackout risk

National Grid has warned that Britain’s electricity will be in short supply over the next few days after a string of unplanned power plant outages and unusually low wind speeds this week, as cheap wind power wanes across the system.

The electricity system operator said it will take action to “make sure there is enough generation” during the cold weather spell, including virtual power plants and other demand-side measures, to prevent a second major blackout in as many years.

“Unusually low wind output coinciding with a number of generator outages means the cushion of spare capacity we operate the system with has been reduced,” the company told its Twitter followers.

“We’re exploring measures and actions to make sure there is enough generation available to increase our buffer of capacity.”

A spokeswoman for National Grid said the latest electricity supply squeeze was not expected to be as severe as recorded last month, following reports that the government’s emergency energy plan was not going ahead, and added that the company did not expect to issue an official warning in the next 24 hours.

“We’re monitoring how the situation develops,” she said.

The warning is the second from the electricity system operator in recent weeks. In mid-September the company issued an official warning to the electricity market as peak power prices climbed, that its ‘buffer’ of power reserves had fallen below 500MW and it may need to call on more power plants to help prevent a blackout. The notice was later withdrawn.

Concerns over National Grid’s electricity supplies have been relatively rare in recent years. It was forced in November 2015 to ask businesses to cut their demand as a “last resort” measure to keep the lights on after a string of coal plant breakdowns.

But since then, National Grid’s greater challenge has been an oversupply of electricity, partly due to record wind generation, which has threatened to overwhelm the grid during times of low electricity demand.

National Grid has already spent almost £1bn on extra measures to prevent blackouts over the first half of the year by paying generators to produce less electricity during the coronavirus lockdown, as daily demand fell.

The company paid wind farms to turn off, and EDF Energy to halve the nuclear generation from its Sizewell B nuclear plant, to avoid overwhelming the grid when demand for electricity fell by almost a quarter from last year.

The electricity supply squeeze comes a little over a year after National Grid left large parts of England and Wales without electricity after the biggest blackout in a decade left a million homes in the dark. National Grid blamed a lightning strike for the widespread power failure.

Similar supply strains have recently caused power cuts in China, underscoring how weather and generation mix can trigger blackouts.

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.

Hydro-Qubec Electricity Theft Ring exposed after a utility investigation into identity theft, rental property fraud, and conspiracies using stolen customer data; arrests, charges, and a tip line highlight ongoing enforcement.

Key Points

A five-year identity-theft scheme defrauding Hydro-Qubec through utility accounts leading to arrests and fraud charges.

✅ Five arrests; 25 counts: fraud, conspiracy, identity theft

✅ Losses up to $300,000 in electricity, 2014-2019

✅ Tip line: 1-877-816-1212 for suspected Hydro-Qubec fraud

Five people have been arrested in connection with an electricity theft ring alleged to have operated for five years, a pattern seen in India electricity theft arrests as well.

The thefts were allegedly committed by the owners of rental properties who used stolen personal information to create accounts with Hydro-Québec, which also recently dealt with a manhole fire outage affecting thousands.

The utility alleges that between 2014 and 2019, Mario Brousseau, Simon Brousseau-Ouellette and their accomplices defrauded Hydro-Québec of up to $300,000 worth of electricity, highlighting concerns about consumption trends as residential electricity use rose during the pandemic. It was impossible for Hydro-Québec’s customer service section to detect the fraud because the information on the accounts, while stolen, was also genuine, even as the utility reported pandemic-related losses later on.

The suspects are expected to face 25 counts of fraud, conspiracy and identity theft, issues that Ontario utilities warn about regularly.

Hydro-Québec noted the thefts were detected through an investigation by the utility into 10 fraud cases, a process that can lead to retroactive charges for affected accounts.

Anyone concerned that a fraud is being committed against Hydro-Québec, or wary of scammers threatening shutoffs, is urged to call 1-877-816-1212.
